Hi all,
I hope somebody can confirm this:
The last days I had some trouble with my networking (both wireless and
ethernet) in forms of high latency, strange arp behaviour etc.
Today I could not even ping anything outside. The problem seemed to be
that:
1. arp replys were ignored
2. if arp -s was used, anything else was ignored for the userspace
That means: I pinged my nameserver, and tcpdump showed request and
replys happily flowing around.
But: ping did not get any packet. It reported 100% packet loss.
That applies to any other userspace prog that uses a socket.
I also had some wireless errors (iwlagn: microcode error) in my dmesg
the days before.
Currently I am using kernel-2.6.29.6-217.2.8.fc11.i586 and the problem
arised after some minutes again. Looks like a buffer run full or
somethign...
Is there a workaround?
