Yes, these are FC2 kernels, v 2.6.7 something, 494 I think. Thanks for
the idea, but for reasons of our own I need to keep these servers on
"stock" packages, updates & such from official fedora sources. company
policy and all. If it were a machine at home, I'd compile kernel source
in a heartbeat.
I'll have some tethereal output for y'all in just a minute. Test:
download webmin's tgz from the UMN mirror (or any mirror if UMN is
unreachable). Just noticed something - a bunch of DUP ACK entries from
my local box to the one I'm DL'ing from, and I noticed that the download
starts with [TCP ZeroWindow]. I'm going to test this against a local
LAN file transfer and see if the same behavior exists. Back in a bit.
On the /var/log/messages output, I'm seeing 2 things I haven't seen
before that may be relevant. Eth0 (single nic machine) keeps jumping in
& out of promiscuous mode - don't know if that's normal or not. #2 is
that many entries have a timestamp that is exactly 5 hours ahead of
local time, ie, ahead of all other entries (GMT format maybe? I'm in
CDT). All such entries are dns lookups. could be normal behavior, I
don't know.
