I am trying to connect to a linux server from my linux machine using SSH over LAN. I don't know what the problem is but sometimes I can ping the server but can not ssh whereas at other times I am neither able to ping nor ssh. While pinging, I found that there is some packet loss as shown below.

ashutosh@ashutosh-ThinkCentre:~$ ping 172.16.5.116

What could be the reason for this?

I think that Superuser is not the right place to evaluate reasons for packet loss.... Likely this is a specific problem with your network... –  klyonrad Jun 15 '13 at 11:17
    
It can be your router. –  idavid Jun 15 '13 at 11:18
