iptables: Unknown error 4294967295

[tripialos]

Greetings

I am facing an iptables issue which is tough to approach and solve it. I tried some Googling but didn't get much apart from some similar cases which are on VPS (not my cases since i am not on a vps but on an embedded system).

When i execute a script which performs various actions which includes rsync to a target using ssh, i am getting the bellow error:

Code: Select all

iptables: Unknown error 4294967295
iptables: Unknown error 4294967295
iptables: Unknown error 4294967295

iptables: Unknown error 4294967295
iptables: Unknown error 4294967295
iptables: Unknown error 4294967295

Any ideas how to troubleshoot this?

I am using CentOS 5.5 (Final) 32bit

I am also adding some additional info which might help:

Look in your logs, probably /var/log/messages for error messages around the time of the problem.

The one time I've seen that message is if you omit the "-p tcp" parameter from a new iptables rule but it doesn't sound like you're hitting this unless your script is adding new iptables rules.

Hi trevor

Thanks for your instant promt.

Indeed the script is adding a few rules to the iptables. I will have a look at the logs see if i can come up with something
