<DIV><FONT face=Arial color=#000000 size=2>I have a setup where I am running on a machine with Red Hat Enterprise Linux Release 3. I have a userland program that is attempting to attach to libipq. When I issue the 'iptables -A OUTPUT -t mangle -j QUEUE' command to attach, the machine hangs. The only way to unhang the machine is to do a hard restart.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>All the machine's filesystems are connected to an NFS server, including the /usr filesystem. So the OS is also running from the NFS server.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>The userland program works correctly on the NFS server and on other machines that are not NFS clients. Is there some way that I can configure iptables to allow the NFS commands to be performed while the '-j QUEUE' command is executing? I believe that is where the problem is occurring because the hang occurs when that command is executing.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Does anyone else have a setup similar to this one? If so, could you share your configuration information?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Any help would be</FONT> greatly appreciated.</DIV>
