Can Not Connect to Network After Cold Installation

Hi Unix Gurus,
I have done HPUX 11iv1 cold installation (3 DVD Installer + Support Plus) on V Class Server and configured nic card for network connection, but very strange fact happened, this V Class can only connect to one of my Unix Servers and can't connect to rest of my servers and clients.These are the output of ioscan:
## ioscan -kfn|grep lan
lan 0 3/0/0 btlan CLAIMED INTERFACE HP A3738A PCI 10/100Base-TX Ultimate Combo
/dev/diag/lan0 /dev/ether0 /dev/lan0
lan 1 5/1/0 btlan CLAIMED INTERFACE HP A3738A PCI 10/100Base-TX Ultimate Combo
/dev/diag/lan1 /dev/ether1 /dev/lan1
lan 2 7/2/0 btlan CLAIMED INTERFACE HP A3738A PCI 10/100Base-TX Ultimate Combo
/dev/diag/lan2 /dev/ether2 /dev/lan2


## lanscan

3/0/0 0x0060B0B2643E 0 UP lan0 snap0 3 ETHER Yes 119

Check /etc/hosts, /etc/nsswitch.conf, /etc/resolv.conf. Did u check your routing tables ?

Re: Can Not Connect to Network After Cold Installation

If i had this problem I would first:

1. Check the entries in /etc/rc.config.d/netconf
2. See if I can ping the default gateway
3. See if I can ping each IP for the lan cards
4. Ping the loop back address
5. check subnetmask and netmask

I can ping my ip, loopback, and broadcast ip but can not ping to default gateway.

Re: Can Not Connect to Network After Cold Installation

Then you can not send packets through gateway. Try to check,

1) physical connectivity
2) Are others machine using default gateway able to ping to that?
3) Is gateway on?
4) If you have any other gateway then change routing setting to that gateway and try out.
5) Add temporary routing setting to local machines in the subnet and check ping connectivity to those machines.

Easy to suggest when don't know about the problem!

Can you put the output of netstat -rn.
Maybe your default gateway isn;t configured correctly.
