Red Hat Bugzilla – Bug 199806
TCP connections to RH9 machines fail to complete initial transaction
Last modified: 2015-01-04 17:28:02 EST
Description of problem:
Version-Release number of selected component (if applicable):
Network TCP for kernel 2.6.17-1.2142
from a FC4 with the latest (as of 20060722) update kernel.
Steps to Reproduce:
1. http://www.nlzero.com or ssh nlzero.com or telnet nlzero.com
2. Grow old and die waiting for the initial transactions to complete.
Website or login prompt or login prompt, respectively.
tcpdump can be generated if needed. (I'd have to reboot to 2142. I am using
2.6.16-1.2115 quite successfully at the moment.)

I have the same problem trying to connect to "http://www.valleyfirst.com". We
tried to telnet to port 80 to check if it is an application issue.
I've downgraded to the same version as the OP and it works properly.

toast is my firewall/nat box, dionysus is my workstation.
[This comment added as part of a mass-update to all open FC4 kernel bugs]
FC4 has now transitioned to the Fedora legacy project, which will continue to
release security related updates for the kernel. As this bug is not security
related, it is unlikely to be fixed in an update for FC4, and has been migrated
Please retest with Fedora Core 5.
FWIW with a recent FC5 install the telnet negotiation seems to complete. I
can't test the ssh because I gave up the account on the old machine for
