Subject2.1.21 bugs..
Found a few bugs in the latest....
If i compile appletalk and ipip as modules... then they are missing symbols
(so says depmod) I've had this problem since at least 2.1.5.. just wanted
to let yall know that its still there...

The other thing... this one got me bad...
i think the ipx stuff is a little screwey... heres my story.. its sad but
true..

I am living on a college campus with an extensive network... I was sitting
in my class bored to tears so I telneted over to my machine... downloaded
the best modutils and kernel.. and built them... installed em.. depmoded
them... etc.. and went ahead and rebooted thinking that if smthing went
wrong it would just lock up and I could fix it upon return to my room. this
was at 11:00 well.. after rebooting... it looked as if it came up half
way... I could ping it but couldnt telnet in, couldnt see it on the
appletalk network, or novell... it looked like my net drivers were screwey
or somthing... but no big deal.. I didnt panic and just said to myself that
I would get back to it later and fix whatever had gone nuts.  For the rest
of the day the campus net was acting very odd... the novell servers (real
servers mind you) were acting wierd... win95's network stuff was odd...
computers lost and gained their novel, and tcp/ip stuff at random and
everything was strange.. at 3 I got a call from one of the schools
sysadmins who was asking wether my machine was up... I said no, thinking I
had crashed it this morning... and he explained how every ipx router on
campus was routing to me. and that I had managed to halt a large portion of
the network single handedly.. I told him that he was mistaken... I couldnt
get to my machine at all... it must be halted. But after he told me that he
had been packet sniffing since noon, and my machine was screaming bloody
murder all over the ipx network I darted to my room too find my machine up
and happy running the new kernel with the network card blasting.  I killed
my nwserv daemon and the campus went back to normal.  Heres the wierd
part... it only effected the area immediately surrounding my machine.. and
an entire subnet it wasnt even a subnet I was in! The reason I couldnt
telnet in to my machine was b/c the network was dead in my dorm.  I had
killed it too.  As soon as nwserv died.. my dorm, the missing subnet and
all the rest of the wierdness went back to normal... 

Now I am not a novell expert at all.. but I think I found some of my
problem...  here is the /tmp/nw.routes that nwserv maintains... 

My machine is named spiff, my ether adress is 00:00:C0:31:AD:71, and my
gateway's ether address is 00:00:0C:05:95:9F...

Anyway in the end... apparently some higher up profs were very angry and
the school is thinking of having me charged criminaly and forcing me to pay
them for the time to pay all the people who doing net-debug.

Please dont ask me to turn my ipx module back on for debugging
purposes... I'm rather hesitant. :)  unless somone would like files
above from an earlier kernel that wont throttle my campus.
