I’m trying to troubleshoot my uncooperating 12.04 ubuntu server. (noob warning here)

Setup:

  • Server has a dhcp assigned route of 192.168.1.20 from the router.
  • Server appears in the router ‘attached devices list’ under that IP as well.

Here’s the problem:

  • Pinging from server results in ‘unknown host’ and ‘destination host unreachable’ respectively.
  • I can’t connect directly from the laptop to the server either (SSH, browser).
    Any ideas what I can do here? What’s confusing me here is that seems to be a connection, but it won’t transmit anything.

Server has worked previously, although that was over a WIFI network due to space constraints and with another router. I think it could be either the router or the server but I suspect the latter is at fault.

Update: Even pinging the server dosen’t work:

--- 192.168.1.20 ping statistics ---
8 packets transmitted, 0 packets received, 100.0% packet loss
