| Posted by rcpkrc, 05-24-2012, 03:12 PM | | hello, l have one default and 4 extra ip. my default domain is working. but my extra ips are not working.
what should l do to make my extra ips work via ssh?

| Posted by Josphin, 05-25-2012, 02:22 AM | | I think there may be a firewall affect in your system.
try csf -a
Or
one of the IP can be assigned for two domains.

| Posted by gigatux, 05-25-2012, 02:28 AM | | I agree that it could be a firewall. If you're not running csf, take a look at iptables -L and iptables -t mangle -L to see if anything could be blocking your new IPs.
If you can't ping your IPs still and don't have a firewall, it might just be easiest to ask your hosting provider to confirm that the IPs are routed correctly.
I don't know if it would affect connectivity, but I noticed that your netmask on eth0 is 255.255.255.255 whereas it's 255.255.255.0 on your aliased interfaces. I would have expected them to be the same so you should check this out.

| Posted by Srv24x7, 05-25-2012, 08:29 AM | | If firewall is also not the issue and even though you are not able to ping those extra ips , Then there is obviously some sort of routing issue with the additional IPs you have on the server. Consult your DC about this.
|
| Posted by rcpkrc, 05-25-2012, 04:43 PM | | l tried both of the codes and commands, extra ips seems added already to the server but l dont kno whow to check if those ips are locked or not.
and the other advices, l can ping those ips 's from inside the server via ssh but l cant outside of the server.
there is firewall scf but l dont think soo its a firewall issue.
any1 can help me about the network issue?

| Posted by markspeed, 05-26-2012, 01:42 AM | | Have you tried contacting hetzner support since your server is with them? Also it seems silly to snip your ip when you've left the bcast/mask there and your ip(s) are easily identifiable anyway.
What is the output of:
ip addr show; ip route show
? Try the basics - 1) can you ping the aliased ips at all ? 2) Can you ping out with them as the source address ? 3) Try stopping iptables/csf if you are running a firewall temporarily to see if you are able to.
If your ips are working and just not working via SSH, it's very likely to be #3, or perhaps you have hardcoded your primary ip in /etc/ssh/sshd_config and sshd isn't listening on the others. netstat -an should help you determine this.

Can you reboot your server and see if the problem persists?

| Posted by anuja9991, 05-27-2012, 10:02 AM | | Please fire following two commands via ssh, it will help you out
/etc/init.d/ipaliases restart
/scripts/rebuildippool
