thanks... got the ttyv8 off...
any idea about the temporary network loss?
not without more info...
it might be you machine or the switch it's attached to..
you may also have a clash with another machine somewhere with the
same IP address.
i forgot to mention one important thing... i can always ping the
machine from within the same network. so it seems that it's not
really the machine itself. the theory about the switch could be -
except all the other machines that are on the same network do not
have that problem. they are always pingable from the outside, even
when the machine in question is not.
and of course there is no other machine with the same ip on that
network. i did check...
so have you left tcpbump running on the machine looking at the
interface in question?
tcpdump -i XX0 -p icmp
this should tell you if it's the incoming or outgoing packets that
are getting lost.
i did similar stuff. but the thing is it's not only icmp. it's tcp
too. basically the machine is unreachable form the outside in any
given time. until i ssh into it from inside. http is not responding
either. and if i leave the dcpdump dumping - detached from the
terminal - it might run out of space....
but you didn't answer the question...
when icmp fails (ping) which packets are seen?
thanks...
thanks....

hi all..
recently i had to change the static ip on a machine here at
work. nothing wrong with that. what's happening with this new
ip (different network) is that for short periods of time
sometimes the machine is unpingable. until i try to login ssh.
as soon as i do that the ping and the rest of network activity
resumes - http.
that didn't use to happen on the previous network. the only
change was the network information. also a bunch of other
machines changed at the same time and none of the others
present the same situation.
the only entry in the log is:
init: can't exec getty '/usr/local/bin/xdm' for port
/dev/ttyv8: No such file or directory
delete or turn off the line in /etc/ttys for ttyv8
(if somebody would explain what this is, that would help too.
since xdm is not really in use and i can't find anything that
would be calling xdm.)
not sure if this has any importance but the card itself is
BCM5750A1 NetXtreme Gigabit Ethernet PCI Express according to
pciconf.
the machine is 7.2 release.
where do i look?
thanks...
