network performance

I moved my hp9000 to another lan. I redefined my network parameters with set_parms.

But now I think something is wrong with the network environment on my machine:

- ping with ip-address is ok:
# ping 53.139.184.13
PING 53.139.184.13: 64 byte packets
64 bytes from 53.139.184.13: icmp_seq=0. time=0. m
64 bytes from 53.139.184.13: icmp_seq=1. time=0. m
64 bytes from 53.139.184.13: icmp_seq=2. time=0. m
...
...
- ping with hostname is very strange:
get the first response after about 5 min:
# ping aegon
--> waiting 5 min
PING aegon: 64 byte packets
64 bytes from 53.139.184.13: icmp_seq=0. time=0. ms
64 bytes from 53.139.184.13: icmp_seq=1. time=0. ms
...

- Boottime of the machine is 1 hour!
Long time to start network daemons for
example 'NFS client subsystem' or 'mail daemon'

What's wrong

Thanks for any help

Check all your network settings again. Look through your logs. It sounds like you missed something when you moved to the new network. Either the system still thinks it is on the old network in one of the config file or your dns is still working with the old network address.

If your network services are taking forever at boot up, then I would assume your system doesn't know itself by name anymore. Which would be dns or your /etc/host file entry.

Hi Ron

Bingo!!!

"nslookup aegon"
--> got time out with the wrong ip-address

I changed the DNS server IP address. Now the system works with no problems
