netstat out takes time to give output

[A.Vishwanath_2]

Dear Admins,

We have HP server which is being connected by DEV from otherside of the world. As you all know when you execute the "netstat -a" command it will print IP & Socket usage information. In this regard we have "Monitoring software" which uses "netstat -a" command as one of the checks and it times out as there is a delay in "netstat" coammand. I would like to know is there anyway to decrease the time it takes to give the output.

TIA,
Regards, Vishwanath

Hi,
I guess the problem may be due to hostname resolution is taking more time. Check your network setting.

Looks like it is a DNS issue and it was resolved by added the source IP to the /etc/hosts file.

Hi,

Forgot to add one point the servers IP address which are connecting remotely are from a different network domain. We don't have DNS entries configured for these IP address in our DNS Server.

Perhaps you should try doing a 'netstat -an' instead. That will output just the IP addresses and not try to resolve the IP address to a name.

Hi,
get the addresses added to your DNS!

In the meantime you could TRY whether this will work:
netstat -a = slow
netstat -an ? fast

It saves the names lookup to translate ip addresses.

If any of the suggestions were useful,please consider assigning points for the help you have been offered in this and your other threads as listed in your profile.

try netstat -an
which does not resolve host name
