netstat -i slow

[Luk Vandenbussche]

The result op netstat -i takes about 30 seconds? It is a server running hpux 11.00 with MC/Serviceguard A.11.12.

Hi,
Just check whether the NIC parameters are configured properly...

Apart from checking the patches for netstat, did you check the network utilization??

If you have glance, start it. (glance -l)
I am not sure about the entry about broadcast in /etc/hosts. Is it really required or not?? I dont have one and it does'nt need to be there.

Everything is configured 100FD Autoneg off.
NIC and switch port have the same settings.

netstat -i will display the output that ip-address resolved hostname's in result.

Are you having all entries of IP-Address in /etc/hosts file there?

Else, problem may be with /etc/resolv.conf file there. Try to rearrange as,

domain united.vicindo.be
nameserver 192.168.1.21
nameserver 10.163.225.12

and try there.

There is a possibility network slow there for operation.

Can you say for this,

time netstat -in
time netstat -i

there.

are all your local IPs in the /etc/hosts file? if not, then delays or retransmissions to your DNS servers may be the culprit. you could try tusc'ing the netstat command - include timestamps and make it verbose, then look for the creation of the "DGRAM" socket and the timestamps on system calls with that file descriptor.

pinging the DNS servers to make sure they are "there" is a good thing too.
