I recently installed Debian etch 4.0, (only successful after reading posts on this forum!) So I thought this would be the best place to seek assistance:
I have a server running Debian etch connected to a BT Adsl modem. On the MODEM I have port forwarding on 21, 80, 3306 and 10000. I have a remote machine that I used to connect over the internet to the server ie xxxx.dynalias.org. Evertyhing was working just fine, then a power cut shut everything down. So I rebooted and discovered that I was not able to connect from the remote machine on port 80 or 10000 but still able to connect on 3306..........ARGGGGGGHHH!!!!
What else should I check? On the top right of my desktop I see an icon that states "No Network connection" Yet I am still able to connect to the internet!
So I rebooted and discovered that I was not able to connect from the remote machine on port 80 or 10000 but still able to connect on 3306..........ARGGGGGGHHH!!!!
Are you sure that these ports are listening on your box? Because if it was your route, it would also block port 3306. What is the output of:
Both ports are listening, so I guess it's your router that has lost either the port-forwarding (NAT) rules, or a firewall on the router or on your server that blocks the trafiic to these ports.
Network-manager will not manage interfaces that you have manually assigned a static IP addrss to in the configuration file, that is why network manager is telling you there is "No Network connection"
Some nvidia chipset motherboards have a BIOS option that causes the MAC address to change on every boot.. that is one possible cause of you changing MAC. If you have an option like that in the BIOS it can easily be disabled.
If your router hasd forwarding enabled the next thing i would look at is local firewall rules..
Many thanks to both of you for taking the time to help me.
So after your comments much googling was done and various fixes attempted, none successful! So I upgraded to debian lenny. Had a problem loading the video driver on reboot "vesa" does not exist, so I did some more googling and ran "aptitude remove xserver-xorg" and then "aptitude install xserver-xorg" and viola!
I rebooted a few times, HWADDRESS and IP address stayed the same, adjusted my /etc/hosts file accordingly......Job done!
