For a service that can optionally listen on a local (Unix) socket, I want to implement detection of a "stale" socket, so it can startup without user intervention in this case by just unlinking the stale socket. As my service is designed around an event loop using pselect, I put all sockets into...

vpnjail: this jail hosts rtorrent, and connects to the outside world over a persistent openvpn connection on tun0.
webjail: this jail hosts standard webservices such as...
I'm a little all over the place with this question so please read to the end. This is a program that connects to the database but really wasn't as I just found out.
I have a program in C that talks to nginx, locally, to serve web pages via FastCGI and this works well. I use spawn-fcgi for the...
From ftp server code, we are limiting the connections to1024 (s.listen (1024) call), but when I do the sockstress tool test it overflowing the listen backlog limit to 12000+ connection. So my system reaching the kern.maxfile limit.
Overflow scenario is Vulnerable to the system with sockstress...
Before www/apache24 was running on this jail. Removed it and restarted the jail after installing www/lighttpd
