Flush ARP cache

Recently one of my vps is not responded to the out side internet. This issue was resolved after clearing my arp cache in the main node.

 Please check the commands I have issued

[root@server.ajeesh.com]# ip neigh flush all;arp -n

After this I could able to ping the server and Internet is active on my vps.

Issue with yum

Please check how i have fixed my yum issue on my vps.
