sam kim_1 — Fri, 02 Mar 2001 18:23:39 GMT

1) we have a HP-k100(10.20) at work
2) some reasons, it cant ping from this machine to another and from another to this either.
3) are there reasons why -or- any ways to fix this problem ??
======================
i already did/checked:
- nic issue (using diff nic, updated driver)
- connectivity issue (not this problem including cable,port,switch,100/full)
- network config issue (ip,snm,dgw,dns)
======================
can anyone help??

Hi,

Are you sure it has a correct default route?

Is there any errors in /var/adm/syslog/syslog.log?
have you tried nslookup from this machine to another?

Just thoughts

Good luck

Victor

You can execute :
netstat -rn |grep default

give the IP address of default gateway

eg,
default 192.168.2.1 UG 0 0 lan0 1500
and then

execute
arp -a
192.168.2.1 (192.168.2.1) at 8:0:20:9d:96:43 ether
IF in the arp table NOT appear the address of default gateway with MAC address, then you have a prblem of connectivity with default gateway because arp can't connected.

Also check the station address,ie the mac address of the network card on both of the systems.Since this can be configured from SAM. A duplicate station address can cause such problem.

Goodluck.
