After that maybe try an ssh to localhost from the console. How is the network configured, from /etc/network/interfaces, or with NetworkManager (if you say you installed ubuntu-desktop on it) ? -- Imre Gergely Yahoo!: gergelyimre ICQ#: 101510959 MSN: gergely_imre GoogleTalk: gergelyimre gpg --keyserver <a href="http://subkeys.pgp.net" target="_blank">subkeys.pgp.net</a> --recv-keys 0x34525305 </blockquote><div>Hi Imre, I will try ssh to localhost. I can not ssh into it from an other pc after it stops accepting connection. I removed NetworkManager and installed wicd. All my other servers have the same setup.( I need gnome for nomachine ssh client) The IP is static, after every reboot ifconfig shows the correct IP and it has internet access. Thank you for the advise I will try the ssh into localhost. lzantal - Laszlo Antal </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> -- ubuntu-server mailing list <a href="mailto:ubuntu-server@lists.ubuntu.com">ubuntu-server@lists.ubuntu.com</a> <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-server" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-server</a> More info: <a href="https://wiki.ubuntu.com/ServerTeam" target="_blank">https://wiki.ubuntu.com/ServerTeam</a> </blockquote></div>
