I installed Ubuntu 12.04.desktop on VMware. I'm connecting to the Internet through a proxy.

I can browse with Firefox, but when I try to ping any domain, I get this message:

12 packets transmitted, 0 received, 100% packet loss, time 11089ms

I put my proxy in network settings, but that didn't solve the problem.

Maybe your firewall filters out icmp packets. Proxy is for http/ftp/https protocols, not for icmp.

how can i check this ? – medo9971 Feb 11 '14 at 21:37
Try to ping from your host os, or try to set VMWare networking to bridged mode (if ping is working from the host), or you can review vmware network setup (is this a vmware workstation or server, esx?) – zilahu Feb 11 '14 at 21:44

Pinging localhost: it is work because the packet doesn't leave the host this will work on ubuntu guest too :) if you use NAT networking in vmware, then the host os firewall can cause troubles. If you use Windows you can enable icmp on the Windows Firewall control panel. E. g: – zilahu Feb 11 '14 at 22:06
