tcp

I have a program that sometime misses to close a tcp connection.

After the program has ended I can see that the port is taken. TCPViewer shows "non-existent" in the "Process" column.

If i try to "End process" or "Close connection" nothing happens.

If i reboot the server the port is released. But how can I tell Windows to release this port without a reboot?

SOLUTION: It was dw20.exe (Microsoft Error Reporting) that was holding it back.

I'm suspecting an attack, but not sure. Intermittently, the web server will stop responding. When this happens… >>> More

(Why can/How are) blocked IPs (get/getting) through my iptables? Hello and thanks for your consideration...

I'm trying to adjust my iptables firewall to increase the security of my server, and I found something a bit problematic here : I have to set INPUT policy to ACCEPT and, in addition, to have a rule saying iptables -I INPUT -i eth0 -j ACCEPT. Here comes my script (launched manually for tests) : #… >>> More
