I believe the original poster was specifically requesting how to increase the File descriptor limits (ulimit -n) past 65k. This is where the limitation would come in most likely for connections he is talking about.
As someone else said, probably not the best place for this, however you can look at /etc/security/limits.conf and play with soft and hard nofile limits. Try unlimited maybe. -----Original Message----- From: Simon Perreault [mailto:simon.perrea...@viagenie.ca] Sent: Thursday, October 14, 2010 11:07 AM To: nanog@nanog.org Subject: Re: How to have open more than 65k concurrent connections?

As long as you're not connecting to the same destination IP/port pair, the same source IP/port pair can be reused. So even for outgoing connections there is virtually no limit.
