Hi Rex,
Yes, tcpdump runs on the same machine. It is interesting that it is
going missing in the kernel. It almost gives more rise to what Greg was
saying about VMWare having something to do with the issue.
<runs off to check the kernel setting in VMWare Server>. I see that
VMWare's "Guest operating system" setting is reporting "Other Linux
2.6.x kernel", where we are running a 2.4.x kernel... do you think this
could have something to do with it? I normally would have thought it
wouldn't have made a difference, unless the Guest kernel was a higher
version.
The iptables line you specified gives me this output:
~# iptables -L -n
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
We are entirely firewalled by appliances, in case anyone decides to ask.
As for the dmesg output, I have attached that as a text file as it is a
little too big to be in a post.
Cheers,
Mike
