socket problem


hello. I have some strange problem with socket connection.
I cannot make connection to localhost (127.0.0.1). Every time I have "connection refused". But i can connect to 22 port where sshd is running. I've tested it under Java and python. In python i have code:

Code:
from socket import socket
s = socket()
s1 = socket()
s.bind(('127.0.0.1', 10)) #used various ports
s1.connect(('127.0.0.1', 10))
error comes in 5th line.
Please note that i have no problems with sshd.
I use Gentoo Linux with 2.6.7 kernel (gentoo-dev-kernel).

I thought that problem is because of lack xinetd. But starting the deamon did not make me happy. Using of tcpd brought same results.

You can only connect to a port if a process is actually listening to it, unless you're connecting to listen to it yourself.

Ports below 1024 are privilaged; you need root permissions in order to start listening to them, so you won't normally be able to listen on those ports anyway (this is why inetd starts running as root).

Also, you won't be able to connect to a port at all if a firewall is blocking your access to it.

Hope that's of some help,

No idea about python. Sorry! But try from both sides. ie listen to socket on both m/cs one at a time. Try many times. Hope u'll get it.
