I can not bind (using C or python sockets) to any port in the range: 59969-60000

Using lsof, netstat and fuser I do not see any processes using these ports.

Other ports such as 59900-59968 and 60001-60009 I can bind to them.

My OS: is CentOS release 5.5 (Final) 2.6.18-194.3.1.el5

There must be something missing? Anyone have any idea how to debug why this port range is not usable?

Cheers, Ivan
