Is that the server you're accessing to or accessing from?
Which host are you trying to access?
provide netstat -rn output.
clearly explain what actually happens.

Hi Incredible ,

I am trying to access from my admin server whose ip is 150.110.221.150.

I could not ssh or ping from my admin server.

The destination machine is 159.17.70.101 sbnismwp2.nam.nsroot.net.

The output of netstat -nr

sbnismwp2# netstat -nr
Routing Table: IPv4
Destination Gateway Flags Ref Use Interface
-------------------- -------------------- ----- ----- ------ ---------
159.17.0.0 159.17.70.101 U 1 98 ce0
127.0.0.1 127.0.0.1 UH 3 1189 lo0
sbnismwp2#


Kindly do the needful.

Are you able to ping to your default router? Btw, you are in a different IP segment. Did you specify the netmasks correctly?
You must check whats the default route for the 150.x.x.x IP. Then you have to add it into your routing table. Also , no firewall should be blocking. If so, then you can access of course

Yes the router is pingable.


sbnismwp2# more defaultrouter

Im not talking about the source. eg. Is the remote machine able to ping the same gateway? It should, then only you can ping across, telnet,ssh etc.. got it?

First of all you must check if the system is up. Go direct to the system console and verify the IP and its plumbed up and is able to ping to its gateway
