Please don't have a go at me re: my lack of knowledge of the Linux kernel; although I've been Linuxing for quite a while, my knowledge of the kernel is fairly limited. This is how I got KISS encapsulated AX.25 TCP/IP working on Linux 0.99-pl15. Note that some of this is conjecture; i.e. it seems to work :-) 1. ftp the AX.25 patches from sunacm.swan.ac.uk:/pub/misc/Linux/Radio/AX25012 (there may be a later revision than 12). 2. Unpack the new files in the Linux source tree - there are a few in net/inet, and one in include/linux. 3. Do a 'mknod /dev/af_ax25 c 30 0' (I don't know if this is actually necessary). 4. Edit drivers/net/slip.c. Search for ax25_test, and change the callsign therein to your own. For example, for my call (G7OMZ-5): static char ax25_test[7]={'G'<<1,'7'<<1,'O'<<1,'M'<<1,'Z'<<1,' '<<1,'5'<<1}; 5. The next bit is quite hacky. There is an implementation of KISS encapsulation in slip.c, but by default it isn't enabled. I couldn't figure out how to make a SIOCSIFENCAP ioctl() call (I didn't know what to give it as a file descriptor), so I just hard-wired it to set all SLIP channels to SL_MODE_AX25 in sl_initialize(). Of course, this won't do if you use SLIP for anything else, so you'll have to hack around in slip_init(). There's a call to sl_initialize() in there, so you'll have to test for certain interfaces and set SL_MODE_AX25 accordingly. I don't know enough about the kernel to comment. 6. Edit config.in, and search for CONFIG_PLIP. Add a line above it: bool 'AX.25 (KISS) encapsulation support' CONFIG_AX25 y 7. make mrproper ; make config ; make dep ; make zImage, then install the new kernel as per usual and reboot. Fingers crossed! 8. When the system comes back up, create a file containing the following commands: port ttyS2 speed 9600 term local 44.131.1.254 remote 44.131.1.57 mode SLIP Replace ttyS2 with the port your TNC is connected to, and the local IP address should be your own. The remote IP address should be either the nearest neighbour through whom you want to route, or your local subnet (mine is 44.131.1.0). 9. Type 'dip filename'. You'll be in terminal mode with your TNC. Put it into KISS mode (usually 'kiss on') and type a ^]. This should set everything up for you. 10. If you type /etc/ifconfig, you should see two messages; one for the loopback device 'lo', and one for 'sl0'. If you type /etc/route, you should see that there is now an entry for 'sl0'. You can either make this your default router (as you would do if there is an Internet gateway nearby) with: /etc/route add default gw 44.131.1.57 ...or (more likely) you will only want to route ampr.org packets through it, which will look like: /etc/route add 44.0.0.0 gw 44.131.1.57 11. That's it! You can now add those commands to your /conf/net/rc.inet[12] files to set it up at boot time.

Ask your friendly system administrator. Using nslookup, set type to MX, and try arrl.org. You should get a response showing you who handles mail for arrl.org. Your mailer is supposed to automatically do this lookup and push the mail along. 73, Dan N1JEB -- --------------------------------------------------------------- Daniel Senie Internet: dts@world.std.com Daniel Senie Consulting n1jeb@world.std.com 508-365-5352 Compuserve: 74176,1347 ------------------------------ Date: 3 Mar 1994 17:02:40 GMT From: ihnp4.ucsd.edu!mvb.saic.com!news.cerf.net!usc!elroy.jpl.nasa.gov!sdd.hp.com!col.hp.com!news.dtc.hp.com!hpscit.sc.hp.com!icon!hpbs3591.boi.hp.com!brianm@network.ucsd.edu Subject: Email address for ARRL?

I should have this added important point to my original post 8^(. Our DNS server can't seem to make any sort of resolution about it either.

If you use nslookup like so: nslookup -query=MX arrl.org You'll find out all you need to know, including the fact that ARRL mail is handled by hosts mgate.arrl.org and uu7.psi.com, in that order of preference. If your system is for some strange reason unable to deal with standard mail addressing via DNS (i.e., MX records), you can use @mgate.arrl.org instead.

You missed where Tim was posting from, Grenoble FRANCE. He wasn't reading from part 97 at all. He was reading from Part XYZZY of the French equivalent of the FCC's rule book. Thats the problem with the Internet. You can have a nice quiet little conversation and not realize that your actually shouting around the world if your not carefull about noticing where all the participants are standing. ;^)....The above wasn't a flame, just an observation.

I tried both the pl15 kernel available on funet.fi and the pl15h I found here at school. When I boot and try to do an axattach, I get an error that looks something like: SIOC(something,something): Invalid argument. It's the same kind of error I get when it can't find the ethernet card. I haven't installed the driver for my ethernet card yet so I don't know if that will fix it. Does anyone know what kernels the ax25 patch works on, and/or what I'm doing wrong on this compilation?
