I am periodically experiencing networking failures. I'd get on the
server after failures and try to ping the machine I had telnetted in
from. I'd get "ping: sendto: no buffer" and have to restart
networking.

I thought I had a decent install, I think, of NetBSD 1.5. 

I put on the basic system and started doing some installing, compiling
configuring. Added a 9G SCSI disk in addition to the 6G IDE internal
drive. I could connect through telnet from my iMac and was working
away setting it up for real work. Then the telnet connections would
stop dead, with no response. 

I could restart by loggin on to the machine as root and restarting
networking with /etc/rc.d/network restart. (is there a good way to
capture the output of this ? - I think the default install adds much
lot I'll never use. I can't really ask about it without capturing the
messages that are produced when networking starts so I can paste it
into a mail message.)


It was behaving well. (I haven't figured out how to get X going yet -
I want to run the server headless and use and X terminal program (MI/X
unless there is a better free Mac X out there) on my imac and most of
the instructions seem to have to do with using the NetBSD machine as
both Xclient and Xserver.) After I did the basic setup to enable
telnet and added my personal account to the wheel group, I was
telneting in to the NetBSD with Nifty Telnet. This is all on an
internal home network and I'd leave the connections up for long
periods of time. I never had more than two connections at the same
time.


If relevant or helpful:

the output of dmesg that clearly (to me ) relates to networking.
