network problem

[Ahmad Munawwar]

Hello,

I having a problem with my network whereby it happen intermittently. The traceroute output shows that even to traceroute it own external lan there was a delay. Sometime the ping output terminted because waited to long.
See attachment for detail.
Would great if someone can give a clue how this could happen and perhaps can provide the solution to it.

Regards,
MUN

Hi,
What is the output of this:

# lanadmin -x 0
or
# lanamdin -x lan0

and for each lan card. I suspect you have a duplexing/autonegotiate mismatch problem.

Regards
Michael

Hi MUN

When you try to ping your IP@, I saw in your log that you ping 190.254.112 from sdp2
It's not a valid IP adress.

Is it a mistake from your manip ?

>sdp2:root> ping 190.254.112 > #
PING 190.254.112: 64 byte packets

# waited for a long time, "ping" is aborted manually

>----190.254.112 PING Statistics----
>56 packets transmitted, 0 packets received, 100% packet loss

Check the following:

Wiring
Routers, ios especially.
NIC card on the HP-UX box
Drivers and software in general on the HP-UX box.

If the lanadmin tests above show discrepencies with the router do the following:

1) Hard code the router to your NIC cards optimal speed.

2) boot the hp box

3) re-run the lanadmin tests.

4) If discrepencies, hard code your optimal nic speeds in this config file, /etc/rc.config.d/hpbtlanconf

Hi,

sdp2:root> ping 190.254.112

( as in your attachment)

190.254.112 is not a valid IP,
try to do with valid IP address

It is not clear why you think this box has a problem. None of your log stuff shows anything wrong locally. One time you left off an octave in the ip address for the ping and another time the destination box seems to have had some sort of problem.

Do you see errors in lanadmin?
If you run a linkloop test on each LAN does that work OK? Does netstat -s show any problems?
