Hi List(s) For a firewall setup I need to know in which range applications like rsh, or better yet the rresvport() libc function allocate reserved ports. Do I have to expect ports in the whole 1..1024 range (maybe omitting those already in use by other servers) or is only a limited range used (like 512-1023). Thanks in advance, Michael. P.S. Yes, I know I shouldn't allow such things through a firewall, but I have to (at least for now) and it's also not into the internet but only between internal departments. -- Michael Weller: eowmob@exp-math.uni-essen.de, eowmob@ms.exp-math.uni-essen.de, or even mat42b@spi.power.uni-essen.de. If you encounter an eowmob account on any machine in the net, it's very likely it's me. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
