My problem is ... peculiar... So, I have a linux box (actually it's booted off floppies - bootdisk & rootdisk) and when I try to resolve an ip address (for instance I type: ping 188.8.131.52) nothing happens. I have put up a sniffer and I noticed that really weird arp request packets are being sent out, look at this:
eth src: 00:c0:13:14:15:16 (OK - my hw)
eth dst: FF:FF:FF:FF:FF:FF (OK - brdcst)
packet arp request (OK)
sender hw: 00:00:00:00:00:00 (?)
sender ip: 0.0.0.0 (?)
target hw: 00:00:00:00:00:00 (?)
target ip: 0.0.0.0 (?)
what the hell... ???
I usually just bring my interface up with a normal:
ifconfig eth0 184.108.40.206
the "noarp" flag is _not_ set. (even if it was no arp frames would have been sent). I have kernel version 2.2.6, and the distibution is slack 4.0. Honestly I don't know what the mechanism for resolving arp is (kernel? what syscall?). I have taken a look at /etc/nsswitch.conf - but it seems ok. I have no clue :( The worst thing is, that it was all working fine not long ago...
P.S. If I missed any important info, please let me know
PSS: I just realized at other times I get totaly random values like:
sender hw: 05 00 00 00 00 10
sender ip: 0.0.1.0
target hw: 00 00 e4 51 00 00
target ip: 220.127.116.11
I realize that something is messed up big time, if anyone can help, I'll be really glad!
