We had a problem with our server last week (Power supply), After fixing it the server is not getting connected to its static ip anymore.

I tried both methods (1) Using Interfaces (2) Using Network Manager

In both cases it gets connected, however it cannot ping any ip.

Since I cannot post more than 2 links ...

Here is the link to the album http://imgur.com/a/1ECiN in which the following commands are bottom to top.


route -n

arp -n




Network manager trial settings

Connection established

However, the ping always fails

I removed dhcp3-client just to see if it was interfering, did not work.

According to this image

network configuration

you disabled automatic network configuration via DHCP (note that the method is “Manual”) and didn't configure a working gateway to the internet manually.

You should fix either of those issues. I recommend re-enabling DHCP by selecting it in the “Method“ combo box of the network configuration dialogue window.
