I'm configuring a local network on a server with centos on eth0 with a certain IP
192.168.1.X and a SIP configuration with given IPs by the provider on eth1. The issue is, I was working remotely
and while setting ifup eth1 the putty access is getting disconnected!! I double checked that the physical connectivity is right and checked the same using mii-tool eth1
by unplugging the cable by the onsite technician. Also, while restarting the network using /etc/init.d/network restart I couldn't connect to the server again
