ping: sendto: Host is down

[andrewdps]

Hi,

I've installed RHEL 5.3 few days back.When I try to ping the remote server it returns


ping: sendto: No route to host
Request timeout for icmp_seq 0
ping: sendto: Host is down
Request timeout for icmp_seq 1
ping: sendto: Host is down
Request timeout for icmp_seq 2
ping: sendto: Host is down
Request timeout for icmp_seq 3
ping: sendto: Host is down
Request timeout for icmp_seq 4
ping: sendto: Host is down
Request timeout for icmp_seq 5


I can ping the local host from the remote mac systems and also ping the server from the server's command prompt.But when I try to ping the remote server from the PC/Mac it get the above error.


Any help would be appreciated

Please explain the setup.

- how many machines are involved?
- what is the name of each?
- what is the IP/netmask of each?
- what is the default gateway of each?
- are there static routes?
- are all links on the NICs and the switch up?
- how are the machines physically connected?

We've only one machine attached to that ip addr

When I checked for the server ip it says the inet addr is 129.174.54.177 and bcast 129.174.55.255

but when I try to ping the images.gmu.edu from a remote client machine it looks for 129.174.55.230

PING images.gmu.edu (129.174.55.230): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
ping: sendto: No route to host
Request timeout for icmp_seq 4

Is something going wrong

[Irithori]

Then ping the IP 129.174.54.177.
If this works, then the DNS setup is wrong.

[andrewdps]

that worked.

Can you look into the private message I've sent you and reply me back

Thank you.
