I have centos server, earlier it had 1 ip [ a.b.c.d ] (external ip , eg., 141.101.114.59).

Now, I bought 2 additional ip [b.c.d.e , f.g.h.i] (external ip , e.g, 190.93.244.58 , 130.93.245.8 ). I have setup two virtual interface with those IPs.

ifcfg-eth0:0
ifcfg-eth0:1

When I am pinging from my system to my additional IPs, it says Request time out. But when I ping it locally, it works.

The two new IPs are not pingable from my system to the server. How can I fix this?

  • More information is required - are the new IP's from the same provider ? [How] have you programmed in the gateway ? The problem sounds like it could be a source-routing problem, but it could simply be that your new IP's are in a different block and the gateway is not [correctly] set up - a lot more detail of your network is required to form a cogent answer.

  • Yes, all ip from same provider. Kindly let me know what command to run for your query.

  • /sbin/ifconfig; /sbin/ip route show will print out your interfaces and routing table. How do you connect your machines together ? (We probably need similar information for the router/gateway)

  • It's not a multiple machine. It is one single machine, where i am configuring multiple ip address, all i want, that, all my IP address can pin and connect to server. for e.g, when i do SSH to a.b.c.d , i can also do SSH to d.e.f.g and do SSH to g.h.i.j
