TidBITS#247/10-Oct-94
=====================

Jonathan Hue concludes his firewalls article from last week, we
   report on another expiring program, and discover a new source
   of Internet provider information. Mark Anbinder looks at a
   potentially dangerous bug in older Hard Disk ToolKit versions;
   Apple gives Cool Tools Awards to eleven worthy individuals and
   organizations; and David Herren offers help on using System
   7.5 with the Chinese or Japanese Language Kits (and a tip on
   System 7.5 installations).

------------------

**"A" is for "Expire"** -- Bill Fleischmann
  <[e-mail]> reports that yet another company
  whose name starts with "A" has announced a problem with a shipping
  commercial program expiring. ACI US announced that 4D Calc 1.2.1
  stopped working on 01-Oct-94. ACI US has placed a fixed version
  with the name 4DCALC.121 in the 4D Modules library on CompuServe
  (GO ACIUS). No word on Internet distribution. ACI US -- 408/252-

**RSI Redux** -- A recent experience reminded me of my repetitive
  stress injuries. I participated in a Wired online conference on
  America Online, and after typing rapidly for an hour, my left hand
  hurt for several days, so much that I wore my wrist brace in bed
  for a few nights. It's more or less back to normal now, but it was
  scary to fall back so quickly, and those of you experiencing
  problems or recovering, please, be careful. There's a new Web page
  with good RSI information, along with pictures and even a few MPEG
  movies - perhaps this is a good time to check it out.

**Need more toner?** Apple has introduced the LaserWriter Pro 810
  Extended Capacity Toner Cartridge (item M3602G/A) to replace that
  printer's original cartridge, offering smaller toner particles,
  improvements in the charging area, and longer page life. (The
  cartridge prints an average of 13,000 letter size pages at five
  percent coverage, as opposed to 12,000 pages for the original.)
  When Apple took the LaserWriter Pro 810 off suspension earlier
  this year (see TidBITS-233_) the company announced plans to offer
  an improved toner cartridge at a later time; it should be
  available by the time you read this. [MHA]


**New versions of Quicken** --  Quicken 5.0 for Macintosh should
  be available on shelves on 13-Oct-94. New features noted in the
  Intuit propaganda include a Financial Calendar, which helps with
  entering repetitive expenses and scheduling recurring
  transactions, such as computer loans and car payments. Other
  emphasized features include an Iconbar (yet another program has
  become a barfly), easier account reconciliation, better online
  help, better QuickFill (automated typing), and QuickMath (a
  calculator by any other name), as well as improved tax planning
  and investment tracking.

  To run Quicken 5.0, you need a hard disk and 2 MB RAM under System
  6 or 4 MB under System 7. The new version runs on Power Macs in
  emulation, and the native version should be ready in 1995. It's
  refreshing to see a new version of a popular program which does
  not require truck loads of RAM, but I'm disappointed that the
  native version isn't out yet and that the nifty sounding Quicken
  Deluxe CD-ROM is only for Windows users. The CD includes the new
  Quicken 4.0 for Windows, Quicken video tutorials, financial
  advice, and various high-end financial tools. Quicken costs $49
  list, approximately $39 mail order, and upgrades are $29.95
  through Intuit or through a $10 rebate coupon in specially marked
  packages. Intuit -- 800/624-8742 -- 415/322-0573 [TJE]


Apple Cool Tools Awards
-----------------------
  by Adam C. Engst <[e-mail]>

  Some time ago, I was telling my grandfather about TidBITS and my
  books and all the stuff I do on the nets, and he asked, "So is
  Apple paying you for this?" I admit, I was a bit taken aback. No,
  they don't pay me, they've never sponsored TidBITS, and there's
  been little acknowledgment that the work I and every other
  Macintosh fan does is in any way appreciated, or even noticed.
  Despite Apple's general ingratitude, many of us continue to
  support the Macintosh merely because we believe it's the right
  thing to do.

  Thus, it gives me great pleasure to tell you that Apple has
  recognized some outstanding members of the Macintosh community. On
  03-Sep-94, Apple's Advanced Technology Group (the group chartered
  with driving long-term technology research and development)
  announced eleven "Cool Tools" awards. Rick LeFaivre, vice
  president of the Advanced Technology Group,  said, "Through the
  creation of these 'Cool Tools' awards, our goal was to recognize
  the work of some of these unsung heroes who have made very
  significant contributions in making it easier to navigate the
  Internet."

  Lest this seem like mere public relations posturing, each
  undoubtedly snazzy certificate comes with a Power Mac 7100
  attached. And, according to John Norstad, it's a loaded 7100 as
  well, with 16 MB RAM, 500 MB hard drive, Apple Adjustable
  Keyboard, and 14-inch color monitor, not to mention System 7.5 and
  SoftWindows.

Without further ado, congratulations are in order for:

* The Internet Society, Reston, Virginia, for its efforts to
  foster a global environment conducive to the easy exchange of
  information and the rapid development of standards and new

  Anarchie author Peter Lewis said in comp.sys.mac.comm, "I'd like
  to thank Apple for the Cool Tools award, and I hope they get a
  tonne of good press from it. It's great to see Apple realizing the
  importance of the Internet, and hopefully some of the cool MacTCP
  apps will make the Mac the platform of choice for connecting to
  the Internet, something that will quite possibly become a major
  factor in buying a computer - and I think we'd all like to see
  more Macs in the world, right? I also hope Apple will make eWorld
  a full Internet gateway so that their customers can use all the
  neat programs. And I'm really looking forward to getting my
  7100. :-)"

  I'd like to echo Peter's sentiments. It's fairly obvious that the
  future lies in connections between people facilitated by
  connections between computers. Apple has always recognized this
  (hence the inclusion of LocalTalk in every Mac and the ease of
  setting up Ethernet networks), but it's pleasing to see the
  company recognize the importance of the Internet in terms of
  communications and computers. From what I've seen (and I've seen a
  fair amount), the Mac is the best Internet client machine today,
  thanks in large part to the MacTCP programmers at Apple and to the
  people and organizations listed above.

  Although any finite list must exclude someone, I and many others
  were surprised not to see Dartmouth College, home of Fetch and
  InterNews, included. Although Fetch is a bit elderly, it's still
  one of the standard Internet programs everyone should have, and
  many people prefer InterNews's interface over others. And, since
  Apple gave awards to both Mosaic and MacWeb, it's not as though
  they needed to limit the awards to a single FTP client or Usenet
  newsreader. I can't give Dartmouth a Power Mac 7100, but I would
  like to extend the same congratulations to the fine programmers
  there for their contributions to the Macintosh Internet community.

ftp://ftp.tidbits.com/pub/tidbits/tisk/tcp/fetch-212.hqx
ftp://ftp.tidbits.com/pub/tidbits/tisk/tcp/inter-news-104.hqx

  Finally, as much as my cynical side wants to say that this is a
  freak occurrence, I sincerely hope that the attention and positive
  press these awards provide for Apple encourages the company to
  periodically continue in the same vein. Apple's most powerful
  allies are its loyal users and developers, and it can only help
  Apple to give them a quantifiable nod every now and then.


System 7.5 & Language Kits
--------------------------
  by David Herren <[e-mail]>

  Despite reports, we have been happily using the Japanese and
  Chinese Language Kits, as well as Arabic, Cyrillic, and Hebrew
  with System 7.5. To make them to work for you:

* Install a _clean_ version of 7.5. That is, don't install it on
  top of an older system. As a tip, press Command-Shift-K once in
  the main Installer window. If you choose Install New System
  Folder, your old one will be renamed Previous System Folder and
  you'll get a new clean one.

* Don't install QuickDraw GX.

* Remove the WorldScript Power Adapter file from the Extensions
  folder. This should be rev 7.5.1.

* Install version 1.1 of the Japanese Language Kit (JLK). Then
  install Chinese Language Kit (CLK) 1.1. These two kits install the
  older version (7.2.1) of the WorldScript Power Adapter which seems
  not to cause any problems.

  We've done testing so far on the Quadra 650, Centris 650, Quadra
  660AV, Quadra 840AV, PowerBook 520c, and the Power Mac 6100. On
  the 6100, we're not having any difficulties even with the 7.5
  release of the Power Adapter.

  The 1.0 releases of the CLK and JLK do NOT work with 7.5, but 1.1
  works as expected. Apple recommends the 1.1.1 release, but I've
  been unable to locate those versions and they certainly haven't
  appeared on any of the developer CDs.


Older Hard Disk ToolKit Driver Buggy
------------------------------------
  by Mark H. Anbinder, News Editor <[e-mail]>

  Users of hard disks and removable cartridge drives with FWB's Hard
  Disk ToolKit (HDT) driver software version 1.3.1 or earlier should
  be aware of a potential data loss problem while using disk
  optimization software or other programs that move or access data
  in chunks larger than 32 MB. This specific problem does not occur
  with HDT 1.5.0, 1.5.1, and the current version, 1.6.0; FWB fixed
  the problem in 1.5.0 without any reports of data loss up to that
  point.

  Data loss only occurs in a limited set of circumstances, in which
  very large amounts of RAM are available to the software moving
  data. The problem cannot occur on a Mac with less than 32 MB of
  RAM, and is unlikely even on systems with considerably more than
  32 MB of RAM.

  Most programs, even when using large files, read and write them in
  small pieces. (For example, Photoshop moves data in pieces no
  bigger than 32 kilobytes, not megabytes.) It's not a good idea for
  developers to attempt to transfer 32 MB in a single pass, anyway.
  Assuming a SCSI bus could transfer data at 3 MB per second, a 32
  MB read would freeze the Mac for over ten seconds, which would
  confuse or concern most users. In addition, such freezes could
  cause network time-outs, especially if virtual memory was
  involved.

  Instances of data loss that may be attributable to this problem
  have reportedly occurred while using Symantec's Norton Speed Disk
  3.0 or 3.1, part of the Norton Utilities for Macintosh package.
  (This is NOT related to an earlier problem reported with Norton
  Speed Disk 3.0 in TidBITS-243_. The earlier problem is fixed in
  3.1.) Two other programs have been identified that might run into
  this problem - SpeedyFinder 7 users should turn off the option
  that allows the program to use all available RAM and Maxima users
  with large RAM disks should turn off the option to use the image
  transfer method and should use file-by-file instead.

  If you have a hard disk or removable cartridge drive and are
  running a version of HDT earlier than 1.5.0, I strongly recommend
  upgrading to a later version (such as 1.6.0) to avoid potential
  problems. If you have a version of Hard Disk ToolKit earlier than
  1.5.0, you must order the update directly from FWB. The price for
  the full version upgrade is $39 plus shipping and handling (and
  sales tax if in California). Shipping and handling is $4 in the
  U.S.; $10 outside. You may order by phone, fax, or email with a
  Visa, MasterCard, or American Express or by mail with a check or
  money order. Please be sure to include your serial number when
  ordering. Hard Disk ToolKit Personal Edition customers can upgrade
  for $29 plus shipping and handling, etc. If you have version 1.5.0
  or later, you can upgrade free of charge if you fax FWB a copy of
  your original invoice, with your serial number written on it.
  Finally, upgrades are free for those who purchased Hard Disk
  ToolKit or Hard Disk ToolKit Personal Edition after 01-May-94.

  If you use a hard disk or removable cartridge drive with
  formatting or driver software older than a few months, check with
  the software's developer to verify that the driver is up to date.
  According to Casa Blanca Works, their Drive7 software (and
  versions 3.0 and later of APS Power Tools, which uses the same
  code) does not suffer from this problem. Although we don't have
  specifics, other drivers may suffer from similar bugs, so to be
  safe, make sure you have the latest version of your driver
  software _and_ avoid the operations mentioned above which may
  attempt greater-than-32 MB transfers, if you have more than 32 MB
  of RAM installed in your Mac.

  HDT comes with hard disks and removable cartridge drives
  manufactured by FWB. It is also sold as a retail software package
  and used to format third-party hard disks. If you are not sure
  whether HDT has been installed on your hard disk, select the icon
  for the disk and choose Get Info from the File menu in the System
  7 Finder. If HDT formatted the disk, the Where line will include
  "FWB" and the drive's SCSI ID (which is not relevant). The Where
  line will end with HDT's version number.

  Given the recent problems Symantec has had with Speed Disk 3.0, I
  would like to stress that this is not inherently a problem with
  Speed Disk, but with an older version of FWB's driver software.
  Speed Disk 3.1 is safe to use (with proper backups) in the vast
  majority of user configurations. I commend Symantec for their
  quick analysis and response to the situation.

Firewalls, Part II
------------------
  by Jonathan Hue <[e-mail]>

  In Part II of our article on firewalls, we look at some of the
  most popular Macintosh Internet applications and describe a few of
  the ways you can make them work from behind a firewall. We also
  look at how you can get through your firewall from the outside
  with your Macintosh. Many of the terms used in this article were
  explained back in Part I, so if you haven't read Part I, check out
  TidBITS-246_ first.

  Note: Always check with your network manager before you run a new
  application which accesses the Internet through your firewall.
  Your company may have a security policy in place and you might
  accidentally violate it by trying to "punch through" your firewall
  with a new program.


**Working with a packet screening router** -- Packet screening
  routers are usually the most friendly towards Macs, since they
  don't favor any particular operating system (the mechanisms
  employed by other firewall components are generally easier to work
  with from Unix clients). It is always possible to configure a
  router to permit a particular Mac client to pass its traffic
  through the router, although some network managers prefer more
  restrictive filtering on their firewall routers, and end up
  blocking the ports which your applications use. In general, if you
  have a good enough reason to pass a certain type of traffic
  through the router, your network manager can configure the router
  to allow it.

  If a firewall uses a packet screening router in conjunction with
  an application-level gateway, you need to worry first about the
  more restrictive of the two components, the application-level
  gateway. However, you may still need to open a hole through the
  router after you get your Mac client to work with the application
  gateway.


**Working with application level gateways** -- Application-level
  gateways are available for most of the popular Mac Internet
  applications. HTTP (HyperText Transfer Protocol, used by Web
  browsers such as Mosaic and MacWeb), Gopher, FTP, and Telnet are
  fairly easy to support, and free gateways are available.

  The most common HTTP gateway is the CERN HTTP server operating in
  proxy mode, which also supports FTP and Gopher. The most secure
  way to run this is to put the proxy server _inside_ your firewall,
  and have the server use SOCKS to get through the firewall. This
  method is more secure because the CERN HTTP server is a large,
  complex piece of code, and one of the basic rules of firewalls is
  that you should not run large, complex pieces of code on them.
  Mosaic 2.0a8 for the Mac supports the CERN proxy server, as does
  MacWeb 1.00A2.2 [1].

  An additional benefit of the CERN proxy server is that it can be
  configured to cache documents you retrieve, thereby reducing the
  network load on the Internet, while at the same time speeding
  future access to the files.

  FTP and Telnet can be proxied with the FTP gateway and Telnet
  gateway from Trusted Information Systems' freely available
  Firewall Toolkit. Although both require slight changes in the way
  you use FTP and Telnet clients, they do work with existing
  Macintosh FTP and Telnet clients, such as Fetch, Anarchie (the TIS
  ftp-gw FTP proxy requires a small modification to work with
  Anarchie 1.3.1), and NCSA Telnet. For instance, with Fetch,
  instead of putting the remote host name in the host field, you
  enter the name of your firewall, and instead of "anonymous" for
  the user, you enter "[e-mail]", where
  <ftphost.domain.org> is the name of the remote FTP server you are
  trying to access. Similarly, with the Telnet proxy, you always
  connect to the Telnet proxy on the firewall first, and then give
  the proxy a command to connect to the remote host. This may sound
  as though you are first logging onto the firewall, and then
  running the client, but in fact, the proxy method is much better.
  Except for making the initial connection, the proxy is transparent
  to the Macintosh client. Furthermore, actual logins onto the
  firewall do not occur (allowing users to log onto the host running
  an important part of your firewall is considered very bad).

  Commercial firewalls based on application-level gateways provide
  similar functionality. Some make the gateway completely
  transparent to the user.

  The most Macintosh-unfriendly firewall is one which uses the SOCKS
  circuit-level gateway. Few Macintosh applications have been
  "socksified." NCSA Mosaic 2.0a8 supports the use of a SOCKS
  gateway, as does the latest version of Peter Lewis's Anarchie.
  SOCKS support is planned for MacWeb as well, but these are the
  only applications I know of which support a SOCKS gateway. As
  mentioned in Part I, it is easy to "socksify" a Unix application
  (source code is not even required on some platforms), but there is
  currently no easy way to support SOCKS on the Macintosh. For more
  information on SOCKS, see:

ftp://ftp.nec.com

  The only consolation in this is that the Web browsers support
  multiple protocols, so you can still get to Gopher and WAIS
  resources through a firewall via a Web browser.

  Anarchie merits special attention, since Archie clients are a bit
  different from most other Macintosh clients. Archie uses the UDP
  protocol, rather than TCP. Because of this, an Archie client
  cannot be "socksified," or relayed by a generic TCP relay program
  such as "plug-gw" from the TIS Firewall Toolkit.

ftp://ftp.tis.com

  Fortunately, there is a solution in the form of a program called
  "udprelay", which is very similar to plug-gw, except it works with
  programs that use UDP. It also provides a SOCKS-like replacement
  library, which is not terribly useful to the typical Mac user,
  although it is useful for those who wish to get Unix UDP clients
  to work from behind a firewall.


**Accessing your network from outside the firewall** -- If you
  have a firewall, you may find you want to access to your network
  from the outside. For example, you might travel to a customer site
  which has Internet access and find you need to FTP a file from
  your desktop workstation. Since the Internet is an untrusted
  network, you should not use reusable passwords when accessing your
  network from the Internet; instead, you should use a strong
  authentication method, such as a challenge/response using hand-
  held authentication tokens or single-use passwords. One way to
  incorporate these devices into a firewall is to present the user
  with the challenge before access to the gateway is allowed. If the
  user does not provide the proper response, access to the gateway
  is denied. Support for this type of authentication is not
  supported in Anarchie or Fetch, so you must use NCSA Telnet for
  Telnet and FTP access when a challenge/response system is used.


**More information about firewalls** -- There are many excellent
  sources of information on firewalls available on the Internet. Two
  of the best are the Firewalls mailing list (available in regular
  and digest format, subscribe by sending email to <firewalls-
  [e-mail]> or
  <[e-mail]>) and the Web site and
  FTP archive at:

http://www.greatcircle.com/
ftp://ftp.greatcircle.com/pub/firewalls/

  The recent book by the architects of Bellcore's firewall
  ("Firewalls and Internet Security" by Bill Cheswick and Steve
  Bellovin) should be required reading for anyone who works with
  firewalls. Trusted Information Systems also maintains Web and FTP
  servers that have good information on firewalls.

http://www.tis.com/
ftp://ftp.tis.com/pub/firewalls/

  [1] Currently, you must use ResEdit to enable MacWeb to use the
  CERN proxy HTTP server. Edit STR# resource number 803 (entitled
  "Proxy Info"). Strings are of the form:
  "<protocol>;<http_proxy_url>"; one per protocol. For example,
  using host <proxy.foo.com> for gopher would be declared as:

    gopher;http://proxy.foo.com/

  Other examples include:

    http;http://proxy.foo.com/
    ftp;http://proxy.foo.com/
