Hi,
I've been asked to clarify the topology of my system.
Very simple setup. All I have is my home box connected to my ISP
thru cable-modem. My NIC is a PCI NE2000 clone using the ed driver.
My ISP uses DHCP to assign my IP, so I run dhclient at boot time
from my rc.conf file. This setup has been running fine for me for over
a year now. Even after my last cvsup/buildworld everything was
still perfectly working.
A few days ago, I started getting a situation where after a few
minutes of operation (after boot), I can't reach anything, not even
my default gateway (assigned by my ISP as part of DHCP).
I've talked to my ISP's tech support rep, and he told me he could
ping my box just fine ( 0% packet loss ), while I couldn't ping
anything ( 100% packet loss ). I also noticed that even though
I can't reach the outside world, I still see some syslogd messages
about failed attempt to connect to my box (I have log_in_vain="YES"
in rc.conf).
Please see attached file for specifics of my system (kernel config
file, dmesg output, uname -a, ps -ax etc...)
I hope this clarifies the situation :-)
Many thanks,
Luc Morin
