Networking problems

[Fabian Briseño]

Hello everyone.
Im new to unix so please be patient.

I installed HP-UX 11.i on a k-460 server, with 896 mb ram, everything went ok, when the system finished installing and I accesed my root account i had no network activity, i cant ping or do a telnet, i checked my network settings and everything looks ok,network cards seem to be up, looking at the rc.log it appears that there is a conflict with the automounter but i dont know if this is related, also sometimes when I autoboot the system hangs when it is checking DNS or NFS services, if you need more info please let me know.

if anyone can help me, i would appreciate it

hi,

It sounds like NFS variable setting problem.
NFS script runs when system is booting up.



edit /etc/rc.config.d/nfsconf

NFS_SERVER=0 (default =1)
NFS_CLIENT=0 (default =1)

if you don't need to set the varible of NFS.

Hi thanks for the reply Patrick.
But I already checked nfsconf in fact I assigned 1 to each option to make them both a server and a client, I don't now if this network problem is patch related becuase of the installation

I have j3514a network cards, also i must note (I see no relation) but I installed a CPU firmware update on this server.

Hi again,Fabian

have you ever tried to boot the system without any pheripheral devices that means there is a core lan card setting only in your box?

why don't you try this?

That's easy way to figure out step by step in what problem is

I do not understand your problem fully but if do not want to run automounter set following variable AUTOMOUNT=0 (ZERO) in /etc/rc.config.d/nfsconf
you can boot system in single user mode and go to multiuser mode by steps.
see any errors in
#dmesg
or
#more /var/adm/syslog/syslog.log
Do you have DNS server too?
do linkloop mac address of lan card, to see man address do
#lanscan
The above will verify LAN connectivity

[Steven E. Protter]

If you installed 64 bit 11i on this box certain HSC lan cards won't be picke up or usable at all.

This box should have a built in NIC card that you can plug in and use ifconfig to configure it.

If you want you add in card to work, you may have to start over with 32 HP-Ux 11i which does recognize more HSC card.

Can you post,

ifconfig -a
netstat -rn
ping 127.0.0.1 # If this does'nt work , your network services r down.
ping OWN_IP_ADDRESS #your interface is not up
ping AN_IP_ADDRESS_IN_THE_NETWORK # Cable problem or you have plugged the network cable on to the wrong interface

Hi,

Can you ping the ip address of the server itself once you are logged into the console. Can you ping the gateway. If you can ping the server ip address but not the gateway, check the default gateway configuration. Can you attach your /etc/rc.config.d/netconf and /etc/rc.log files for us to take a look.

Hope this helps.

Thankyou everyone for your help, the problem was with my network cards (I have 3)i did some config movements on them I changed network cables and disabled one of them and enabled another. and that seemed to fix my problem, again thank you to everyone, all of you were very helpfull.
