'ping' error

[Amod Phadke]

Here is some background. One of our non-production servers became suddenly inaccessible. No one was able to ping or telnet to the server. I managed to login at the console and checked the 'routing table' entries. They were all perfect. But the server was not able to ping any other server on the network. When I tried to ping the server's own IP address I got the following error.

# ping sihp8001
PING sihp8001.ap.pg.com: 64 byte packets
ping: sendto: No buffer space available
ping: wrote sihp8001.ap.pg.com 64 chars, ret=-1
ping: sendto: No buffer space available

Does anybody know what this error means ? Which buffer space it is talking about ? I checked the memory/swap usage and it was normal.

I got the problem resolved by rebooting the server but am afraid I will not be able to do so on our production servers.

Hi,

Make sure your 'inetd' daemon is running. The other thing you might like to do from your console is make sure that your lan card is still working.

Using 'lanadmin' is a good place for this.

You could also look at stopping and re-starting your network services.

# /sbin/init.d/net stop
# /sbin/init.d/net start

I would first check that the lan card is enabled. And how many lan cards you may have. If the card is lan0 then type:
$> ifconfig lan0
and see if the status is "up". You should see something like this:

#> ifconfig lan0
lan0: flags=843
inet 192.168.0.24 netmask ffffff00 broadcast 192.168.0.255

Notice the if not up then you can enable it with:

#> ifconfig lan0 up

also a look at the output from netstat:
#> netstat -rn

Hi,
This message can be generated when network interface send buffers are full. So try resetting the card once. If the Problem persists , change the network card because some
memory chips on the network interface might have gone bad.
