Description of Problem: When I use ip masquerading with ipchains, I segmentation faults after a short time and then the whole system crashes Version-Release number of selected component (if applicable): How Reproducible: I have a lan and a cable modem. The cable modem is connected to the linux box and I share the internet connection with the LAN. On the lan there are two computers: the linux box and a Win Me computer. I used ip masquerading (with ipchains) and put an masq entry in the forward chain. Everything works perfect, only that after a time, the linux box crashes. Steps to Reproduce: 1. Configure ipchains (masq entry in forward chain) 2. wait for a time, starting programs will make it crash faster 3. Actual Results: Every application begins giving segmentation faults.
The original 7.1 kernel (2.4.2-2) had a bug where masquerading of gnutella and some other programs caused such behavior; it is fixed in the errata (update) kernel we released a while ago (2.4.9-12). See http://www.redhat.com/support for more info on how to install this kernel (or use up2date)
