Hi list, I don't know if this are a iptables or a kernel or where it come from, but after this, I cannot more login on my server, so I think that it's a kernel/net problem, so I ask here :) I see that on my syslog there are a ton (milions) of: Jul 22 11:44:51 srv syslog-ng[22054]: Error accepting new connection; error='Too many open files (24)' But this is a "simple" server that do only nat and some other, simple, tasks, and there are no programs that can open so many files. cat /proc/sys/fs/file-max 202771 Where it can born? Do I have to change some /proc/* parameters? Thanks a lot! Michele
