Also included you'll find a few words of wisdom as well as some general information for the A/UX community. This list assumes that you are familiar with Unix (to some extent) but are curious about A/UX's eccentricities. The list will concentrate on A/UX 3.0 but may also have info about previous versions. If you don't understand something in the FAQ List, and a "Point of Contact" isn't specified, then contact me and I'll attempt to help or else point you to someone who can. In any case, let me know how I can make the list more clear. This FAQ is written in a format that EasyView (for the Mac) can understand and make use of. EasyView provides a very nice front-end for viewing, browsing and reading the FAQ. EasyView is available via anon-ftp on jagubox.gsfc.nasa.gov. The list will be posted biweekly (every other Tuesday) on comp.unix.aux as well as news.answers and comp.answers. It is also available via anonymous ftp on jagubox.gsfc.nasa.gov. There is a frozen FAQ that deals with A/UX 2.0.1 which is available via anon- ftp on jagubox (FAQ.aux.201). This FAQ will be posted monthly (or so) on comp.unix.aux. A/UX 3.0.1(dt) is officially released. It's the version of 3.0.1 for the rest of us (3.0.1 is "officially" the AWS95 server-version of A/UX). It is, except for some minor cosmetics, a binary-exact copy of 3.0.1 but does not include the server-related applications of 3.0.1. Expect this FAQ to change to be more representative to 3.0.1 than to 3.0. At some point, the 3.0 FAQ will get frozen and the 3.0.1 one will be the "current and supported" FAQ. I will tend to use 3.0.1 as the name of the general version of A/UX and AWS95 3.0.1 as the version for the AWS95 even though this is kinda confusing. This may change depending on the actual release name of 3.0.1... 3.0.x will be used to mean 3.0, 3.0.1 and 3.0.1dt. This FAQ is "copyrighted" in the same sense that all other FAQs are copy- righted: the FAQ may be freely redistributed as long as the author's/editor's name and this notice is included.

Does that mean I'll miss out on all the neat Gnu-stuff like gcc? 10) I have an EtherNet card that works fine under the Macintosh operating system but not under A/UX. Why? 11) Can I use my scanner under A/UX? 12a) How come my Login screen is gray, not color? 12b) How come my screensaver only works on my main Login screen and not my other ones? 13) Even though I have lot's of swap space and only a little bit is being used, I STILL get a lot of messages saying that my swap space is running low. What the buzz? 14) How can I copy a complete file system from one disk|partition to another? 15) What's with UUCP? + 16) How can I log anonymous ftp entries? in.ftpd has a -l option, + but it doesn't work. 17) I'm trying to use a SyQuest drive under A/UX but it refuses to work.

When I use 'setport' to enable the port, I get a "no such device" error. Configuring /etc/inittab to respawn getty on the port has no effect. 19) I am using and depending on /etc/hosts to do all my hostname resolving (i.e. not using named or /etc/resolv.conf). How come I can't mail to other hosts, but I can ping|ftp|etc... them? 20) My MacOS partition mounts fine under MacOS but it doesn't show up under A/UX... Why? 21) I've ported Elm (or other mail reader) and it doesn't seem to work. Why? 22) What 3-button mice work under A/UX (and X)? 23) How come when I do a 'df' as a regular user, it shows me a different number of free blocks compared to when I run it as 'root'? 24) Does A/UX LocalTalk support IP? 25) How do I get MPW 3.1 to work? It hangs my system... 26) Can I refer to a file on my Mac system from within A/UX? 27) How can I adjust the amount of virtual memory Finder uses? 28) Is it worth getting a cache card for the IIci? 29) How do I keep command lines that I edit with "backspace" from erasing the prompt? 30) When I try to mail something, I get the following error message: "Cannot read frozen config file: not a typewriter". What's wrong? 31a) I have MacsBug installed. How can I trigger it? 31b) Sometimes my MultiFinder environment (and/or CommandShell) freezes up; how can I unfreeze it? Should I hit the Interrupt switch? 32) Is there an archive of comp.unix.aux out there somewhere? 33) My site is not upgraded to EtherTalk Phase 2 yet... can I use Phase 1 under A/UX? 34) What languages are available for A/UX? 35) How can I figure out the /etc/disktab entry for my hard disk? 36) How come I can't use color under X? 37) What are Right-To-Copy and Right-To-Upgrade licenses? 38) How do I set up my Mac and A/UX to enable remote logins via a modem on tty0? 39) How come I can't used 'talk' with some of the other Unix boxes out there, and they can't talk to me? 40) I'm having trouble transfering files between A/UX and my MacOS disk... Also, sometimes things get transfered fine, othertimes not. What's going on? 41) Using the command shell interface, I'm trying to access some Mac files (that have strange names) but I can't; the program returns an error and I can't access the file. What's going on? 42) How can I reports bugs that I find? 43) Which serial cards work under A/UX? 44) I heard the the Installer for 3.0.x works on "any" 3rd party hard disk. Well, it doesn't on mine! 45) I'm using a LaserWriter IIg with A/UX 3.0 and whenever I print some- thing to it through 'lpr', the first line of the page is cut off. Why? 46) Whenever I try to run xinit (or startx) from the CommandShell I get a fatal server error. Why? 47) I'm trying to access my tape drive using 'tc' (with something like "find . -print | cpio -o > /dev/rmt/tc1") but it doesn't work... 48) What CD-ROM drives are compatible with A/UX 3.0.x? 49) Do I install CDEVs and Extensions in the System Folder on MacPartition or on the "/" A/UX disk. 50) I heard that A/UX requires a special version of System 7 to boot... Is this true? 51) I've tried to install the CD Remote extension to A/UX so that I can play audio CD's, but it doesn't work... 52) What CD-ROM formats does A/UX support? 53) How can I add printers other than those available in Chooser? 54) After the Mac environment crashes (or when I use MacsBug), the Desktop gets all screwed up... Argg!! 55) My MacOS partition(s) only show up on the Desktop when I login as root. Why? 56) For some reason, my CommandShell only responds to a keyboard event after it receives a second event. For example, typing "a" won't show until I type something else or click the mouse. What gives? 57) Can A/UX 3.0.x run System 7.1? 58) Is OSF/Motif available for A/UX? 59) How can I convince A/UX to forward IP packets? 60) While trying to port some software, the Makefile looks for a program called 'ranlib' and dies when it can't find it. What is it and where can I get it. 61) What 3rd party accelerators are compatible with A/UX? 62) Since A/UX 3.0.1 will no longer be bundled with RetroSpect for A/UX, how can I get it? =============================================== **** List of Contributors to A/UX FAQ List **** ----------------------------------------------- The editor would like to thank all the various people who have contributed to the A/UX FAQ List (both those that submitted questions as well as those who submitted answers).

See BNU/HDB UUCP above. /usr/include/dir.h: If entered through dirent.h and _SYSV_SOURCE is defined, rewinddir() is incorrectly "defined". It assumes that you are linking -lposix and will use the "real" rewinddir() function found there, when, in fact, you should #define rewinddir as done with _BSD_SOURCE. *** A hacked version of dir.h is available on *** *** jagubox.gsfc.nasa.gov. It only assumes -lposix will *** *** be included (and the real rewinddir() called) if *** *** _only_ _POSIX_SOURCE is defined *** /usr/include/sys/types.h: Incorrectly defines size_t as signed int when every other header file defines it as unsigned int. *** Fix is very simple... edit /usr/include/sys/types.h *** *** and change it from signed to unsigned *** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Performance related patches: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ MacOS System Heap Expansion: Not as robust as the _real_ System 7.0.1 capability, thus pre- venting you from loading lots of memory hungry Extensions and CDEVs. *** 3.0 patch is now available *** *** on aux.support.apple.com in supported/3.0 *** + inetd: + *** Unofficial replacement is available on *** + *** jagubox.gsfc.nasa.gov in pub/aux/apple.fixes. *** + *** This replacement is based on the BSD-reno inetd *** + *** and allows such nice features as rereading /etc/servers *** + *** on receiving SIGHUP and specifying options for *** + *** called daemons *** tc (tape driver device driver): Reports incorrect file number when 'mt' is used to skip files (fsf and/or bsf).

Since the ports are pretty straightforward, only a few are actually available in their ported form (please see Q&A #6): (those that have been personnally verified by the editor are marked with '#') o Cnews (Ver. ??) # Elm 2.4.21 ( use -lbsd and edit config.sh and "undef" d_locale) o Ghostscript 2.3 o GNU Stuff (all are pretty much straight-forward and compile "right out of the box"): binutils 1.9 bison 1.21 # diffutils 2.3 emacs 19.7 (diffs on jagubox) # fileutils 3.6 # find 3.8 (to allow 'find' to recognize user=nobody, compile with 'cc') flex 2.3.7 gawk 2.1.5 (use '-traditional' with gcc) # gdbm 1.5 # grep 1.6 # make 3.67 sed 1.1.6 shellutils 1.8 Smalltalk 1.1.1 # tar 1.11.2 # textutils 1.6 # gzip 1.2.2 o Gwm 1.7h # less 177 # NetHack # nn 6.4.18 # nntp 1.5.11 # perl 4.035 (use '-lm -lPW -ldbm -lbsd', get "fixed" dir.h to avoid needing -lposix for rewinddir(), use gcc if possible, make sure d_voidsig is correct ("define" if using ANSI, "undef" if not), and undef d_ndbm while defining d_dbm in config.sh). # perl 4.036 (Don't answer "aux" but instead let the configure script work it's magic) # rn 4.3.54 # rn 4.4.1 o SB Prolog 3.1 (minor changes in the builtin directory) # smail 3.1.28 (get the AUXsmail.tar.gz file on jagubox for A/UX diffs and patches) + # tcsh (compiles out of the box) # trn 3.0 ======================================================== **** Partial list of compatible shareware|freeware **** -------------------------------------------------------- ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Popular shareware|freeware: ~~~~~~~~~~~~~~~~~~~~~~~~~~~ ++++ This is by No Means a complete list!!! ++++ o BBEdit Lite (2.3) - _really_ nice and good replacement for TextEditor (see Hints and Words Of Wisdom) o CFloppy (1.0) o Disinfectant INIT (3.2) o Extension Manager (1.8) o Facade (1.x) o FMbackup 1.0.4 (prevents having to totally rebuild Desktop when A/UX crashes... See Q&A 54) o GateKeeper (1.2.5) - For some reason, "Show Log" doesn't work although log entries _are_ made. Chris Johnson knows about this and is looking into it. o Gregs Buttons (3.0) o MacsBug (6.2.x) o Maelstrom (1.03) - crashes sometimes, but heck it does that under MacOS as well :) o Moire (3.22) - even works under login screen ## kinda incompatible with FMbackup (prevents "Finishing up..." window) o NewLook (2.0) o Solarian II (1.04) o Suitcase (1.2.6) - the latest version, 1.2.12, doesn't (if you have ATM, you can use Font Porter instead which automatically installs Font suitcases) << ED: well, now I hear that 1.2.6 may not even work... I'll keep you all posted >> o Windows (2.1) ~~~~~~~~~~~~~~~~~~~ Popular commercial: ~~~~~~~~~~~~~~~~~~~ The following is a _very_ short list of some known compatible 3rd party applications, CDEVs, Extensions, etc... This is by no means a complete list since the vast majority of MacOS programs work just fine under A/UX (see Q&A # 4). But the following ones are kinda popular and they get asked about alot: o Access PC (2.0) o After Dark (2.0u and later) - some displays don't have enough memory to work so the default (low memory) one comes up o ATM 2.0.3 o ATM 3.0 o DOS Mounter (3.00) - but _boy_ does it slow down floppy disk access! o Illustrator 3.2 o Now Utilities 3.0.2 (New Menus requires that the Control Panel alias point to a Control Panel which is on a HFS partition... this means you need to copy the A/UX CP over to a HFS partition (such as MacPartition) and then make and alias and copy that over to the Apple Menu Items folder under A/UX. Super Boomerang doesn't seem to like 3.0) o PC Exchange (1.0.1) o Photoshop 2.0.1 <mostly> (Gamma, which is included, does _not_ work) o Premiere 1.0 o StrateVision 3D 2.6.1 (requires a patch from Strata) o Streamline 2.0 <mostly... not 32-bit clean> o Type Reunion 1.3 o VersaTerm Telnet (etc...) Tool ==================================== **** Hints and Words Of Wisdom: **** ------------------------------------ o By default, A/UX allocates only 10% of memory for disk buffers (that is, the value of 'NBUF' is 0... see kconfig(1M)) If you have a lot of RAM, you could greatly increase system performance by increasing the allotment. However, you cannot use kconfig to specify "20%" but you must give it an actual number to use. The way to determine the number of buffers being used, run "pstat -m". This will give you the number of buffers that are currently allocated. For example, if the value is 1000, then you know that to increase the number of buffers to 20%, you must use 'kconfig' to set 'NBUF' to 2000. Please note that if you change the amount of RAM you have, you'll need to change the value of 'NBUF.' I suggest that before you add|remove RAM, you use 'kconfig' to reset 'NBUF' to 0, then do the RAM change and see how your system performance is. If needed, you can then use the above to increase (or decrease) the number of disk buffers. To more accurately reflect the geometry of the FFS, try increasing SBUFSIZE to something like 4096 or 8192 with a corresponding decrease in NBUF by a factor of 2 or 4, respectively (to maintain the same amount of buffer memory used). o You can run A/UX on the original MacII, however the PMMU chip must be installed. You can also use one of the many 68030 upgrades for the MacII, such as the Marathon '030, but the MacII ROMs won't recognize the PMMU capabilities onboard the CPU. You'll need to get the MacII FDHD ROM Upgrade Kit. This kit replaces your ROMs with IIx ROMs, thus enabling you (and A/UX) to use the upgrade. The kit also replaces your SWIM chip (floppy controller) enabling you to use FDHD disks (if such a drive is installed) too... thus the name of the kit. This kit can be had for about $120 although some dealers also include a FDHD drive as well, bumping the price up to about $430. o You can configure the built-in serial ports for hardware handshaking (RTS & DTS) _or_ dialup security (DTR & CD) but not both, due to the lack of a sufficient number of modem control lines. o When using ftp, unless you are _sure_ that a file is, in fact, a true Text file, set the ftp mode to Binary. This is especially true when downloading GIFs and "true" Mac files. If it's a BINHEXed file or a uuencoded file, then you can specify Ascii mode (in some cases, it's required). If the file you wish to download has the ".tar" or ".Z" suffix, then you _need_ Binary; if the suffix is ".uu" or ".hqx" then use Ascii. If you are using a MacOS-ftp utility, then using MacBinary may confuse A/UX (well, the Unix side of it). If the file is a tar file (for example), compressed or not, MacBinary attaches some MacOS "information" to the file that tar can't handle. Use 'fcnvt' to change the file to Apple Double to "strip" this extra by separating the forks. o To download GIF files via anon-ftp, be sure to specify Binary mode. Then use 'setfile' to create the correct Type and Creator fields (for, example, for Giffer use 'setfile -t"GIFf" -c"Bozo"'). You can then keep this file on your A/UX disk or transfer it over to your MacOS disk (See Q#40). o If you want to rebuild the "/" desktop, be _sure_ to avoid circular symbolic links (links to "." and/or "..") or else you'll be waiting a looooong time. o The full functionality of System 7 Tuner 1.1.1 is included in A/UX 3.0 even though A/UX "only" has System 7 Tuner 1.0. Installing version 1.1.1 could cause problems running the Finder environment. Installing LaserWriter 7.1.1 (which is on the TuneUp 1.1.1 disk) causes no problems at all. o With the newest version of HDB UUCP (1.16 - see above), use the "-u" option on 'getty' to keep /dev/tty?? settings sane. Also use the "-t" option with a value like 60 or so to make getty hang up a hung login attempt. o If your A/UX setup is a true multi-user system, or, at the least, has Guest as an active account, it is a Very Good Idea to give each user their own personal System Folder (use 'systemfolder'). This is _very_ true for root! As root, you should also avoid using the global System Folder (mac/sys/System Folder) as an alternate Sys. Folder... there's very little need to do so anyway. Oh yeah... you can't just copy /mac/sys/System Folder to something like $HOME/System Folder... you must use 'systemfolder' and add/change/delete things as required. o It's very easy to replace TextEditor as your Finder-double-click text editor. All you need to do is copy the application to /mac/bin (make sure that it's permissions are 755 bin|bin), edit /etc/profile and /etc/cshrc to change FINDER_EDITOR to point to the application. Now, A/UX text files will show up as that application's filetype. An _excellent_ replacement is BBEdit Lite (v 2.3). It is really recommened! o A/UX's 'login' supports additional dialup security. This is enabled by creating|editing two files: /etc/dialups and /etc/d_passwd. The format of /etc/dialups is a list of ports that you want to have dialup passwds. eg: /dev/tty0 /dev/tty10 The format of /etc/d_passwd is a list which associates a password with a login program (which is the last field in /etc/passwd). eg: /bin/sh:&nk7h7ak92j3H: /bin/ksh:8hw$jK4ft92jx: /bin/csh:: /usr/lib/uucp/uucico:: In this case, if anyone attempts to login on ports tty0 or tty10 and are using 'ksh' or 'sh', they'll get asked for a secondary (dialup) password. Users using 'csh' or 'uucico' will not. All other logins that use login programs not entered in /etc/d_passwd (like, for example, /usr/local/bin/bash) will _not_ be allowed to login on the "secure" port. o If you want to install a program that uses a "complex" installation procedure (like for Canvas, Word, Stuffit, etc...) then you should not try to do a fresh install under A/UX. Instead, install under the real MacOS, reboot A/UX and then install needed files to your A/UX System Folder. Programs that, when installed, hack around with the System (beyond things like Fonts) itself, most probably won't work under A/UX, since you really can't patch System (unless you are handy with ResEdit and know exactly what resources to add|change... even then, you are taking a chance...) ============== **** Q&A: **** -------------- Read on MacDuff... ================================ 0) What's A/UX? Is it any good? -------------------------------- A/UX is Apple's implementation of Unix (it's Apple's UNix) for the Macintosh computers. A/UX merges two computing environments, Unix and the Macintosh Finder OS, and provides the full functionality of both. A/UX is based on AT&T Unix System V.2.2 with numerous extensions from V.3 (such as streams) and BSD 4.2/4.3 (such as networking, the Fast File System, job control, lpr, NFS with Yellow Pages, SCCS and sendmail 5.64). It also provides full POSIX compliance. A/UX provides SYSV, BSD and POSIX compatiblity switches and libraries. A/UX is fully compiant with the System V Interface Definition (SVID). A/UX provides all three standard shells: sh, csh and ksh. X-Windows is also provided standard. A/UX 3.0.x incorporates System 7 for the Macintosh allowing for the use of the vast majority of Macintosh applications under A/UX. System7 and Unix and fully integrated under A/UX 3.0.x with the Unix file system being seen as a disk drive by the Finder. There are quite a few people who feel that A/UX is a near-perfect implemen- tation of Unix. Of course, every operating system (even AIX!) has it's share of devotees, so that's not a very valid scale of whether the system is any good. A/UX _is_ Unix... it's not some form of pseudo-Unix. It insulates the user from Unix, if required, but the System Administrator will need to become Unix-aware. Furthermore, if you want straight Unix, you can get it... it's not a chore to bypass all the "gingerbread." People may also complain that A/UX is based on an "obsolete" version of AT&T Unix (V.2.2). In many ways, Apple's extensions make A/UX very V.3-like (V.3 is in many ways an enhanced V.2... it even uses the V.2 kernel)... The list of extensions to A/UX are impressive. Compare what you get standard with other systems and you'll be shocked! On some, 'cc', 'f77', NFS, etc... are costly options. The main consideration (and opposition) to A/UX is the platform it runs on: The Macintosh. Some consider this a boon, others a bust. At present, Apple's top-level workstation is the Quadra 950, a 33MHz 68040 based system. Some consider this obsolete; others consider it overkill; others consider it, like Goldilocks, "just right." If you need super-fast state-of-the-art number crunching capability then A/UX may not be for you... the Q950 benchmarks at maybe 9-14 SPECmarks (depending on compiler used, external cache size, etc...) and you can get lots faster with other platforms. Of course, you'll have to "settle" for their operating systems, but if you need it, then that's how you'll get it. Of course, this doesn't mean that A/UX "crawls"... There are very few people who need this type of performance though. If you need (or just _want_ ) a Unix workstation with the speed and power of Unix and the user interface and application selection of the Macintosh then A/UX is the way to go. In many, many ways, A/UX is the Unix "for the rest of us"... even if we are long-time Unix junkies. If you love the Mac, you'll love A/UX; if you love Unix, you'll love A/UX... and if you want a near- perfect marriage of the two, then you'll love A/UX. Yes, A/UX is good... very, very good :) ===================================================================== 1) What's the minimum system I need (CPU, disk and RAM) to run A/UX? --------------------------------------------------------------------- A/UX 3.0 works on the MacII (with PMMU _or_ 68030 upgrade with FDHD ROM's installed), IIx, IIcx, IIci, IIfx, SE/30, IIsi (with 68882 chip) and the Quadra 700|900|950 computers. A/UX 3.0.1 adds support for the Q800 and Centris Machines (the Centrises _must_ have the real 68040 w/FPU - See Q&A #2b). A/UX does not support the ClassicII, PowerBook, Duo or LC families. Recall that A/UX _is_ UNIX and thus contains some very hardware specific drivers. It's for this reason (and not Apple not doing things correctly) that A/UX won't work on newly released platforms. To support a new platform, at least _some_ work (and possibly extensive work in some cases) must be done. If you really want to cut it close, 8MB RAM and an ENTIRE 80MB hard disk will just make it. You'll have little room for user files (unless you clear out some space by removing /games and maybe /catman) and depending on your workload, may suffer from low performance (due to swapping... you may even encounter the infamous swap messages :) A much better system would be 16MB of RAM and about 200MB of disk space. This would give you much more room to grow as well as sufficient RAM to increase your performance (assuming that you tune some kernel parameters). All in all, more RAM is prefered: 20MB (or more) is ideal. ================================= 2a) What's new about A/UX 3.0.x? --------------------------------- A/UX 3.0.x incorporates the full functionality of System7. It supports the QuickTime multimedia extension and the new Mac Quadra computers. A/UX 3.0.x now includes X11R4 in it's distribution, including MacX. Installation of A/UX is much easier that it was before and can be installed on any 3rd party hard disk using the "new and improved" HD Setup application (see Q#44 though). A/UX 3.0.1 adds support for the Q800 and Centris machines (as long as they have the real 68040 w/FPU - See Q&A #2b). ======================================= 2b) What's the word on A/UX 3.0.1(dt)? --------------------------------------- 3.0.1dt is the version of A/UX for the rest of us (the original version for the rest of us was to be 3.0.2). 3.0.1(dt) adds support for the Q800 and the Centris machines (650 and 610) as long as they have the _real_ 68040 chip (68RC040) installed (Support for the C650 is official; support for the C610, which _requires_ the 040 be replaced since none have the required one installed, is non-official but known and verified). 3.0.1(dt) is an exact binary-copy of 3.0.1 (which is officially the version of A/UX for the WGS 95 server) except for some minor cosmetics and the exclusion of the server-related applications. This includes RetroSpect for +A/UX. (see Q&A #63). Some of the major differences between 3.0.1 and 3.0.1dt +include: + o Buffer cacher size (default kconfig parameters) + o Packages installed during Easy Install + o Swap space size on Easy Install + o Autologin enabled in 3.0.1 (AWS95) + o lpr daemon off in 3.0.1, on in 3.0.1dt + o Partition choices in HDSC SetUp +As you can see, they are all related to how the system is setup... ========================== 3a) How can I order A/UX? -------------------------- A/UX is available preinstalled on Mac systems or on CD-ROM. To find the nearest A/UX reseller, call 1-800-538-9696. You'll need access to a compatible CD-ROM drive to install A/UX (or a friendly dealer if you go that route). +The part numbers for 3.0.1(dt) are: + M0598LL/C A/UX 3.0.1 CD-ROM product ($795) + (contains Essential Manuals) + M0597LL/C A/UX 3.0.1 Essential Manuals ($329) + M0430LL/C A/UX 3.0.1 Programmers Manuals ($329) + M0431LL/C A/UX 3.0.1 Administrators Manuals ($329) + M0599LL/C A/UX 3.0.1 Update (updates previous ($250) + versions to 3.0.1) + M0489LL/B A/UX 3.0.1 Programmers Manual Update ($285) + M0490LL/B A/UX 3.0.1 Admin. Manual Update ($285) +If you are interested in upgrading your Q950 to the Apple WGS-95 Server +(which uses A/UX 3.0.1) here are the part numbers: + M6940Z/A WGS 95 PDS Upgrade Kit ($2499) + M6945Z/A WGS 95 PDS + DAT Upgrade Kit ($4399) ============================================ 3c) What's the upgrade path for A/UX 3.0.1? -------------------------------------------- You can upgrade to 3.0.1 (from any other version of A/UX) by purchasing the A/UX 3.0 CD-ROM Product Upgrade (Apple part # MO599LL/C). The suggested price is $250. It's recommended that if you do upgrade, that you completely repartition your disk via the Installer for two reasons: 1. The default (suggested) partition sizes have changed 2. You install 3.0.1 on a "clean" system. =================================================== 4) What Mac applications are compatible with A/UX? --------------------------------------------------- It would be to list the applications that aren't compatible (the list is much, much shorter)... The _vast_ majority of applications that run under System 7 will run under A/UX 3.0.x. In fact, before System 7 was released, A/UX 2.0.x was actually a good litmus test whether the application was 32-bit clean and would run under System 7. The only applications that are _sure_ to fail are those that try to access hardware _directly_, such as HD utilities or backup applications. A/UX 3.0.x provides both 24 and 32-bit modes, so if the application doesn't run under 32-bit mode, try it under 24-bit. One key note: if the program uses a "complex" installation procedure (like for Canvas, Word, Stuffit, etc...) then you should not try to |do a fresh install under A/UX. See the above Hints and Words Of Wisdom ==================================================== 5) Can I use my Teac|DAT|etc tape drive under A/UX? ---------------------------------------------------- A/UX 3.0's 'tc' device driver (version 1.40) officially and totally supports the following tape drives: Qualstar 9 track Archive 4mm DAT Archive QIC Teac DCAS 600 Exabyte 8500 <<ED: no go with the 8200s>> DC2000 Please note that all the devices except for the Qualstar 9-tracks require 8k-blocking when used through 'tc'. This means you will need to use 'tcb' or 'tbb' as a filter ('dd' will also work during reading). You should also specify 8k blocking (or a multiple thereof) when using dump.bsd. Jim Jagielski has created a replacement for 'tc' to fix some of version 1.4's bugs as well as to provide support for the WangDAT 1300/2600, Cipher, SONY SDT-4000/2000, WangTEK and HP DAT drives. It also works with the Exabyte 8200s as well as having some nice features. The driver is currently at version 3.26 and is available via anon-ftp on jagubox (If needed, it can be Emailed). This version is a replacement for 'tc' (it also includes a replacement for 'mt' and some man pages as well). Tony Cooper has written a VERY nice double-buffering copier that greatly increases the speed of backups; it's called 'tbb.' It works quite nicely with 'tc' (assuming the correct blocking factors)... Craig Ruff (cruff@ncar.ucar.edu) has written a Teac device driver also, which works with both the 150 MB and 60 MB drives. You get the complete source so you may "adjust" the driver if you want for other drives. The Teac driver is available via anonymous ftp of jagubox.gsfc.nasa.gov. %%% For more information about 'teac', please contact Craig via E-mail %%% %%% For more information about 'tc', please contact Jim via E-mail %%% ============================================================== 6) How come rn|elm|less|etc... acts weird concerning signals? -------------------------------------------------------------- Well, it's not really them at all. Many people have found that more than a few ports require the addition of the 'set42sig()' call to enable BSD 4.2 signal delivery. The best place to add this is as the 1st executable statement under "main() {" Another point about porting applications: A/UX's 'cc' does provide "strict" BSD, SystemV and Posix libraries. If you are porting a BSD program, you can enable BSD "emulation" by adding the "-ZB -lbsd" options to your 'cc' command line. In fact, using just the '-lbsd' option alleviates the need for adding the 'set42sig()' call mentioned above and is, in many cases, the suggested option. Compiling with gcc also helps out a great deal. ================================================ 7) What screen-savers are compatible with A/UX? ------------------------------------------------ Moire (ver. 3.22) works quite well under A/UX (2&3), even under the Login AfterDark (2.0u and later) also works but some displays may not have enough memory under Login so the "low-memory" display will be used. Moire and FMbackup seem a bit incompatible. They both function fine together but the combination prevents FMbackup's "Finishing up..." window from displaying, although FMbackup does, in fact, finish up. Darkside is also available. Unlike other screen savers, Darkside is an application, not an INIT. This means it won't work under the Login screen. The latest version of Darkside is 4.0 and will _not_ work on Pre-System7 systems, so don't attempt to use this under A/UX 2.0.1. Moire is available via anon-ftp on jagubox. ================================ 8) Is X11R5 available for A/UX? -------------------------------- Yes! Thomas Eberhardt (thomas@mathematik.uni-Bremen.de) has ported X11R5 and the binaries (which includes full shared libraries) for A/UX are available via anon-ftp on wuarchive.wustl.edu under systems/aux/X11R5 (our overseas friends should get it from ftp.uni-stuttgart.de due to US Export regs). Patches for X11R5 compiled with gcc are also available. It looks like it results in a nice 10-20% increase in performance! Thomas has "taken over" X11R5 with his new port; John Coolidge used to do it... %%% For more information about X11R5 for A/UX, E-mail Thomas %%% ================================= 9) FSF GNU doesn't support A/UX? --------------------------------- 9) I've noticed that FSF GNU doesn't support A/UX. Does that mean I'll miss out on all the neat Gnu-stuff like gcc? Although it's true that FSF is "boycotting" Apple and A/UX (FSF doesn't like Apple's predisposition of suing to protect "look and feel"), ports of most Gnu applications are available. Of particular interest is gcc version 2.4.5 which has been ported by John Coolidge (coolidge@apple.com) and is available via anon-ftp on wuarchive.wustl.edu in systems/aux/gnu. The binaries, sources and diffs are all available. GCC version 2.4.5 for A/UX has been ported and is available... Highly recommended! As a nice compliment to using GCC, gdb (4.9) is also available. %%% For more info about gcc for A/UX, please contact John via E-mail %%% ============================ 10) EtherNet cards and A/UX ---------------------------- 10) I have an EtherNet card that works fine under the Macintosh operating system but not under A/UX. Why? The reason is because to access the card (which is seen as a device by A/UX), you need an A/UX device driver for it. This is NOT the same as the stuff you had to install under the MacOS for it to work. Now A/UX includes drivers for the Apple EtherNet card (they aren't installed by default though), but they don't work with most of the 3rd party cards except for the 3Com "EtherLink NB" and Asante "MacCon" cards. They are 100% register compatible with their Apple counterparts, so you can use Apple's 'ae' driver with them. Drivers for the EtherPort II cards are available via anon-ftp on jagubox. However, the drivers for the "old" EPII cards (full length) only support TCP/IP (they were written for A/UX 1.1 but will work under 2.0.x). As far as other cards are concerned, you will have to ask the vendor for A/UX drivers for it. Please note that there have been numerous reports about problems with the EtherPortII cards, A/UX and the IIfx and IIsi... you are warned :) ===================================== 11) Can I use my scanner under A/UX? ------------------------------------- A/UX 3.0.x fully supports the Apple OneScanner as well as providing better support for SCSI devices. A/UX will still use its own SCSI driver, however. =========================== 12) Login Screen questions --------------------------- 12a) How come my Login screen is gray, not color? 12b) How come my screensaver only works on my main Login screen and not my other ones? Because that's the way Apple wanted it :) Actually, the reason why is because the 'scrn' resource is missing from 'System' in /mac/sys/Login System Folder. If you're handy, you can copy 'scrn' from some other System and paste it in Login's using ResEdit. Make sure the "Is Color" field in 'scrn' is "1". ============================== 13) Swap space error messages ------------------------------ 13) Even though I have lot's of swap space and only a little bit is being used, I STILL get a lot of messages saying that my swap space is running low. What the buzz? Unix is justifyably concerned about having adequate swap space. A system crash caused by this beast is a sight to behold. However, A/UX seems EXTREMELY nervous about the amount needed before it starts getting fidgety. If you do a "/etc/swap -l" and see that you're only using a small portion of your swap space and have a "lot" left, then you can safely ignore the messages (just how much is a "lot" is hard to say, but if you have 25000 blocks and are only using 1000 or 2000, then I'd say you were fine). If you DO need more swap space, then you have a few options: a. Using 'kconfig', reduce the number and size of buffers. This isn't really a good idea since it could really degrade performance as well as possibly causing more panics. b. Add more swap space. Fine, if you have it. You could either add another disk as swap (nice) or repartition your present disk to create a larger Swap partition (Ack!). c. Add more memory. If you have more memory, then this will reduce the need to augment it with swap space... RAM's cheap too! ============================================= 14) How can I copy a complete file system... --------------------------------------------- ...from one disk|partition to another? You have three options: dd, dump.bsd and cpio (pax MAY work but tar won't since it won't handle special-type files). If the two partitions are the same size, you can use 'dd' (to copy c0d0s0 to c5d0s3, e.g.): $ dd < /dev/rdsk/c0d0s0 > /dev/rdsk/c5d0s3 To use dump.bsd, you can use the following command (this assumes that the destination disk in mounted on /mnt and you want to copy the root file system which is on SCSI 0... of course, you must be root and it would be MUCH better to do this in single-user mode): $ dump.bsd 0f - /dev/rdsk/c0d0s0 | (cd /mnt; restore xf -) To use cpio, you must use it in a pipe with find. For example, to copy /usr (let's assume it's on it's own file system) to another disk|partition (assume it's mounted on /mnt) then you can use (you can add the "-depth" flag to 'find' if you want): $ cd /usr $ find . -print | cpio -pdmuva /mnt The problem with this is that if the mount point of the destination disk falls under the file system's directory you're trying to copy, you'll load up your destination disk. For example, the following would NOT work: $ cd / $ find . -print | cpio -pdmuva /mnt because 'find' would see the stuff in /mnt (which you just put in there) and try to copy in back to /mnt! To way to avoid this is by adding a little filter: $ cd / $ find . -print | grep -v '^./mnt*' | cpio -pdmuva /mnt If you have GNU find, then you can use it with it's '-xdev' option, which prevents find from walking through other file systems: $ cd / $ find . -xdev -print | cpio -pdmuva /mnt dump.bsd creates a "truer" copy of your file system (the access and modification dates aren't mucked with... with the find/cpio pipe, at the least the directory dates are touched) but it won't backup named pipes... ====================== 15) What's with UUCP? ---------------------- UUCP under 3.0 is very improved over it's previous "incarnation" under 2.0.1. 3.0.x uses HDB (for HoneyDanBer) UUCP instead of standard UUCP. Some nice things are bidirectional getty (also known as uugetty in other Unixs) which allows both incoming and outgoing communication over serial lines as well as better performance and reliability. I hear that setting it up is _much_ easier as well. You may seriously consider getting Alexis Rosen's "sendmail.cf" file for use under UUCP sendmail. This config file has been modified to allow UUCP and sendmail to work beautifully together. You may also want to consider simply installing smail to replace sendmail. Be sure that you are running the latest version: 1.16. It can be found on aux.support.apple.com in aux.patches/supported/3.0. Be sure that you get the new dial.o on ftp.apple.com (pub/earlw/dial) to avoid breaking syslog. ========================================== +16) How can I log anonymous ftp entries? ------------------------------------------ in.ftpd has a -l option, but it doesn't work. Jim Jagielski (jim@jagubox.gsfc.nasa.gov) has hacked in.ftpd to enable logging via the syslogd daemon. It also pays extra close attention to anonymous ftp logins. It's available (as well as other ports|hacks) on jagubox. Also available on jagubox is a set of patches and files required to compile and run wuarchive's ftpd server under A/UX. This is a super- nice ftp server! +The real reason why '-l' doesn't work with in.ftpd is that there's no +real way to send this option to the daemon. A/UX 'inetd' doesn't allow +you to add options to '/etc/servers'. John Coolidge (coolidge@apple.com) +has ported the BSD-reno version of 'inetd' to overcome this limitation. +This version of 'inetd' also has some nice features, such as rereading +/etc/servers when sent SIGHUP. It's available via anon-ftp on jagubox. %%% For more info, contact Jim %%% =================================== 17) Using SyQuest disks under A/UX ----------------------------------- 17) I'm trying to use a SyQuest drive under A/UX but it refuses to work. I keep on getting a "more data than device expected" error message. What's wrong? The "problem" is with the generic SCSI disk driver under A/UX. For SCSI drives, there are certain parameters that may be adjusted by the user; these parameters are grouped in "pages." One such page concerns how the disk responds to and recovers from errors: the Error Recovery Page. A/UX expects the parameters in this page to have certain values. Now the vast majority of SCSI disks have the values set as expected, but this isn't the case with SyQuest drives. There is one parameter (PER) which is opposite than expected by A/UX. When A/UX trys to set this value to what it wants, however, the SyQuest drive reads this "request" wrong (the request is 16 bytes but the SyQuest only reads 4) so the SCSI Manager reports the error. Tony Cooper (tony@marc.cri.nz) has written a Mac application which sets the Error Page values correctly: Fix Error Page. This application must be used under the MacOS. It can be found on rascal.ics.utexas.edu as well as on aux.support.apple.com (aux.patches/unsupported/2.0). You can also use the FWB Hard Disk Toolkit - World Control Application to enable the PER bit in the recovery page (Page #1). By the by, here is the /etc/disktab entry for SyQuest: # SyQuest disk # Syquest|syquest|S45:\ :ty=winchester:ns#34:nt#2:nc#1275: ================================ 18) 'getty' problems under A/UX -------------------------------- 18) I'm unable to start a getty process on a built-in serial port. When I use 'setport' to enable the port, I get a "no such device" error. Configuring /etc/inittab to respawn getty on the port has no effect. AppleTalk is probably enabled for the port. The getty process can be started temporarily by turning off AppleTalk via A/UX's Finder Chooser and THEN using the 'setport' command. You can permanently disable AppleTalk by reconfiguring the kernel with "newconfig noappletalk". If you wish to keep the drivers installed in the kernel but still want to "permanently" disable AppleTalk, you can edit /etc/startup to prevent AppleTalk from initializing and /etc/inittab can be editted to start getty. (NOTE: /etc/startup is regenerated by newconfig so you'll have to redo this if you reconfigure the kernel). If you don't have an EtherTalk card installed, then you can also modify /etc/appletalkrc to point to "ethertalk0" instead of "localtalk0". Doing this stops AppleTalk from bothering the serial port because it tries to use the non-existant card. ====================================== 19) sendmail problems with /etc/hosts -------------------------------------- 19) I am using and depending on /etc/hosts to do all my hostname resolving (i.e. not using named or /etc/resolv.conf). How come I can't mail to other hosts, but I can ping|ftp|etc... them? Well, the problem is actually with sendmail (in /usr/lib). sendmail (under A/UX 2.0 and later) assumes the use of a nameserver. Pre-2.0 versions were "adjusted" to look in /etc/hosts if any nameserver call failed (which it would if it wasn't running, of course :). Jim Jagielski (jim@jagubox.gsfc.nasa.gov) has hacked sendmail 5.65 for A/UX to allow it to also check /etc/hosts. The source code is available via anon-ftp on jagubox. You may also want to upgrade to smail 3.1.28. smail is a very powerful yet easy to configure (and maintain) replacement for sendmail. It can both query the NameServer as well as look in /etc/hosts to "interpret" hostnames. The required A/UX-related diffs and patches, which were written by Bob Denny (denny@alisa.com) are available on jagubox. %%% For more info, contact Jim %%% ////////////////////// END OF PART 1 OF 2 \\\\\\\\\\\\\\\\\\\\\\ -- Jim Jagielski | "Supreme executive power derives from jim@jagubox.gsfc.nasa.gov | a mandate from the masses, not from NASA/GSFC, Code 734.4 | some farcical aquatic ceremony."
