Only able to ping local interface

Big Ant — Fri, 15 Jan 2010 21:25:06 GMT

I have a customer that changed the Ip address of an existing server to the same Ip as his HP-UX server. I gave instructions on how to change the Ip on the HP-UX server and once he did this he could not communicate with any server on the network. I asked him to verify the network and the subnetmask and everything is good. Any suggestions on what to check next ?

ping localhost but not router on that network ?

maybe wrong interface ?

correct IP for vlan on switch ?

have we waited long enought ( minute + ) for arp caches to flush ?

if you post the following we can save some time.

lanscan
netstat -in
netstat -rvn
ifconfig lanx

HI

a) ping the interface - if it responds then nic is good

b) ping the gateway - cable is connected to nic and you're on the network

See set_parms command to redo any network configuration.

Thanks for your replies . However the customer has gone home for today and since it's Friday I guess I will pick up on Monday. But I had him do all of the suggestions already and everything looks fine. I tried to connect to the management port to troubleshoot myself but I just discovered that the vlan I created on their router for the Management LAN has been disabled.

Hi,
Check /etc/rc.config.d/lanconf file
#lancscan
#ifconfig lanx (x=0,1..)
check /etc/hosts file
