OK, so there's an incorrectly configured something or other on my FC
machine
that dtops TCP from working but allows UDP to work just fine.
I've run through all of the rlevant tools (netstat, tcpdump, ifconfog etc
etc.), and compared it to anthother machine running FC5, but cannot
for the
life of me spot the difference.
For example, using firefox to view slashdot, I see the standard UDP
traffic
for DNS.
Then, TCP SYN from my machine to their srver, ans SYN,ACK from them
back to
me, and finally an ACK from me to them. And then.... nothing. no
traffic, no
response.
Interestingly, if I try & coinnect to the apache instance on this local
machine, I don't even get that far... there is no TCP traffic at all.
Also, if I try to use another TCP reliant app, Thunderbird, to connect
to a
local IMAP server (on the same subnet) I get the SYN/ACk/ACK setup,
but no
further traffic.
I have SeLinux set as disabled
I have no iptables rules in effect.
The only thing that changed is that I did a yum update, installed a new
video card (nvdia 7300) and the appropriate driver, and rebooted...
Running 2.6.16-1.2107_FC5smp
Nuke that kernel, it was a problem child. And then reboot to 2096 long
enough to
go get 2111 which is now released for FC5.
