Computer crashes when using ip masquerading (ipchains)
Last modified: 2007-04-18 12:38:51 EDT
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):
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
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)
