From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041020 Firefox/0.10.1 Description of problem: With kernel 2.6.9-1.667, I can't print to my Linksys printserver with iptables enabled, although I CAN print successfully if I disable iptables. The printserver (PPSX1) is set up using the "Networked UNIX (LPD)" option. This same setup works fine with iptables enabled for earlier kernels (e.g., 2.6.8.1), but not with the fedora or vanilla 2.6.9 kernel. I've attached a file with a few relevant lines using ethereal capture. Version-Release number of selected component (if applicable): kernel-2.6.9-1.667 How reproducible: Always Steps to Reproduce: 1. Boot up with 2.6.9-1.667 kernel. 2. Try to print over network to Linksys printserver. Actual Results: Doesn't print. Expected Results: Should print as it does with earlier kernel versions.

Is that anything like the Linksys PSUS4? Bug #135502 found that the PSUS4 is really bad. In any case if this truly is a regression in upstream 2.6.9, please bring this issue to the upstream netfilter.org project. They are best able to figure this out.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
This bug has been automatically closed as part of a mass update. It had been in NEEDINFO state since July 2005. If this bug still exists in current errata kernels, please reopen this bug. There are a large number of inactive bugs in the database, and this is the only way to purge them. Thank you.
