- your ARCnet card.

-
- Since no one seems to listen to me otherwise, perhaps a poem will get your
- attention:
- This is alpha software
- If it works I DO CARE.
-
- Hmm, I think I'm allowed to call that a poem, even though it's only two
- lines. Hey, I'm in Computer Science, not English. Give me a break.
-
- The point is: I REALLY REALLY REALLY REALLY REALLY want to hear from you if
- you test this and get it working. Or if you don't. Or anything.
-
- ARCnet 0.32 ALPHA first made it into the Linux kernel 1.1.80 - this was
- nice, but after that even FEWER people started writing to me because they
- didn't even have to install the patch. <sigh>
-
- Come on, be a sport! Send me a success report!
-
- (hey, that was even better than my original poem... this is getting bad!)
-
- Anyway, enough complaining. Let's get started:
-
- ---------------------------------------------------------------------------
-
- These are the ARCnet drivers for Linux.
-
- We're now back to more ALPHA releases after the 1.01 release which made it
- into Linux 1.2.2, so please be careful, and send all possible
- success/failure reports to me. If I don't know when/if/how it works, I
- won't be able to answer people's questions. Do we want that? Of course
- not.
-
- Once again: DO send me success reports! I want to know if this is working!
- (You know, it might be argued that I'm pushing this point a little too much.
- If you think so, why not flame me in a quick little e-mail? Please also
- include the type of card(s) you're using, software, size of network, and
- whether it's working or not.)
-
- My e-mail address is:
- apenwarr@foxnet.net
-
-
- Where do I discuss these drivers?
- ---------------------------------
-
- There is a mailing list specifically for discussion of the ARCnet drivers
- for Linux, and anything you might want to interface them with (ie. DOS).
- I'll also post new versions of the Linux-ARCnet distribution to the list in
- tar-gzip-uuencode format.
-
- To subscribe to the list, send a message to listserv@807-city.on.ca
- with the following line in the BODY (not the SUBJECT) of your message:
- subscribe linux-arcnet YOUR REAL NAME
- Remember to remove your signature, or you'll get an error back.
-
- Send all bug (or success) reports to me or to the list.
-
- The people on linux-net@vger.rutgers.edu have also been known to be very
- helpful! :)
-
-
- Other Drivers and Info
- ----------------------
-
- Also, SMC (one of the companies that makes ARCnet cards) has a WorldWideWeb
- site you might be interested in, which includes several drivers for various
- cards including ARCnet. Try:
- http://www.smc.com/
-
- Performance Technologies makes various network software that supports
- ARCnet.
- http://www.perftech.com/ or ftp to ftp.perftech.com.
-
- Novell makes a networking stack for DOS which includes ARCnet drivers. Try
- ftp'ing to ftp.novell.com.
-
- You can get the Crynwr packet driver collection (including arcether.com, the
- one you'll want for arcnet cards) from oak.oakland.edu:/simtel/msdos/pktdrvr.
- It won't work perfectly on a 386+ without patches, though, and also doesn't
- like several cards. Mail me if you want a fixed version. (Ahem: I may or
- may not have a 100% fixed version by the time I get your mail!)
-
-
- Loadable Module Support
- -----------------------
-
- This is a available starting with 0.42 ALPHA.
-
- Configure and rebuild Linux. When asked, say NO to "arcnet support" if you
- want loadable module support.
-
- make config
- make dep
- make clean
- make zImage
- make modules
-
-
- Booting into your "ARCnet" Kernel
- ---------------------------------
-
- If you're using a loadable module, you need to use insmod to load the
- module, and you need to specify various characteristics of your card on the
- command line. For example:
- cd /usr/src/linux/modules
- insmod arcnet.o io=0x300 irqnum=2 shmem=0xd0000
- You can also add a num=1, num=2 etc for additional arcnet cards that will
- use arc1, arc2 etc for their device names (instead of the default, arc0).
-
- Otherwise the driver will load and probe for your card automatically.
-
- Now go read the NET-2-HOWTO and ETHERNET-HOWTO for Linux; they should be
- available where you picked up this driver. Think of your ARCnet as a
- souped-up (or down, as the case may be) ethernet card.
-
- By the way, be sure to change all references from "eth0" to "arc0" in the
- HOWTOs. Remember that ARCnet isn't a "true" ethernet, and the device name
- is DIFFERENT.
-
-
- How do I get it to work with...?
- --------------------------------
-
- NFS: Should be fine linux->linux, just pretend you're using ethernet cards.
- oak.oakland.edu:/simtel/msdos/nfs has some nice DOS clients. There
- is also a DOS-based NFS server called SOSS. It doesn't multitask
- quite the way Linux does (actually, it doesn't multitask AT ALL) but
- you never know what you might need.
-
- DOS: If you're using the freeware arcether.com, you might want to install
- the source code patch. It helps with PC/TCP, and also can get
- arcether to load if it timed out too quickly during initialization.
- Mail me if you need a precompiled version of arcether.com. (ie. you
- if don't have a DOS assembler)
-
- Windows: See DOS :) Trumpet Winsock works fine with either the Novell or
- Arcether client, assuming you remember to load winpkt of course.
-
- LAN Manager and Windows for Workgroups: These programs use protocols that
- are incompatible with the internet standard. They try to pretend
- the cards are ethernet, and confuse everyone else on the network.
- However, v1.93 ALPHA and later of the Linux ARCnet driver support
- this protocol via the 'arc0e' device. After setting up arc0 as
- usual, ifconfig and set up routes to your ethernet-encap hosts
- through arc0e. There may be non-Microsoft products that support
- this protocol as well, so it was changed in 1.93 ALPHA from arc0w
- to arc0e.
-
- Using the freeware Samba server and clients for Linux, you can now
- interface quite nicely with TCP/IP-based WfWg or Lan Manager
- networks. In addition, the Linux host can be used as a router
- between the standard and WfWg protocols, so hosts that could
- previously never talk to each other should now be able to.
-
- This feature is still in early testing, so please e-mail with any
- comments/questions you might have.
-
- OS2: Has not been tested. The "correct" solution would be to buy either of
- IBM's "TCP/IP for OS/2" or "Warp Connect" packages. However,
- ftp.microsoft.com also has a freeware Lan Manager for OS/2 client
- which should use the same protocol as WfWg does. This has not been
- tested, however. Please mail me with any results.
-
- NetBSD/AmiTCP: These use an old version of the Internet standard ARCnet
- protocol which is incompatible with the Linux driver at present.
- Work to support these is underway and should be available in a
- standard release soon.
-
-
- It works: what now?
- -------------------
-
- Send mail describing your setup, preferably including driver version, kernel
- version, ARCnet card model, CPU type, number of systems on your network, and
- list of software in use to me at the following address:
- apenwarr@foxnet.net
-
- I do send (sometimes automated) replies to all messages I receive. My email
- can be weird (and also usually gets forwarded all over the place along the
- way to me), so if you don't get a reply within a reasonable time, please
- resend.
-
-
- It doesn't work: what now?
- --------------------------
-
- Do the same as above, but also include the output of the ifconfig and route
- commands, as well as any pertinent log entries (ie: anything that starts
- with "arcnet:" and has shown up since the last reboot) in your mail.
-
- If you want to try fixing it yourself (I highly recommend that you mail me
- about the problem first, since it might already have been solved) you may
- want to try some of the debug levels available. For heavy testing on
- D_DURING or more, it would be a REALLY good idea to kill your klogd
- daemon first! D_DURING displays 4-5 lines for each packet sent or
- received. D_TX and RX actually DISPLAY each packet as it is sent or
- received, which is obviously quite big.
-
- You can run the arcdump shell script (available from me or in the full
- ARCnet package if you got it) as root to list the contents of the arcnet
- buffers at any time. To make any sense at all out of this, you should grab
- the pertinent RFC's. (some are listed near the top of arcnet.c). arcdump
- assumes your card is at 0xD0000. If it isn't, edit the script.
-
- Buffers #0 and 1 are used for receiving, and Buffers #2 and 3 are for
- sending. Ping-pong buffers are implemented both ways.
-
- If your debug level includes D_DURING, the buffers are cleared to a constant
- value of 0x42 every time the card is reset (which should only happen when
- you do an ifconfig up, or when Linux decides that the driver is broken).
- This is to make it easier to figure out which bytes are being used by a
- packet.
-
- You can change the debug level without recompiling the kernel by typing:
- ifconfig arc0 down metric 1xxx
- /etc/rc.d/rc.inet1
- where "xxx" is the debug level you want. For example, "metric 1015" would put
- you at debug level 15. Debug level 7 is currently the default.
-
- Note that the debug level is (as of v1.90 ALPHA) a binary combination of
- different debug flags; so debug level 7 is really 1+2+4 or
- D_NORMAL+D_INIT+D_EXTRA. To reach D_DURING, you would add 8 to this,
- resulting in debug level 15.
-
-
- I want to send money: what now?
- -------------------------------
-
- Go take a nap or something. You'll feel better in the morning.
