Set up Networking after a cold install to HPUX11.00

[Belinda Dermody]

I am doing a cold install tonight on a HP9000/H50 system from 10.20 to 11.00. I have takened a lot of notes, vgexport and vgimport have saved all kinds of files, made make_recovery tapes, complete backups. My question and concern, is that I am not that familiar with networking. I have my host file, resolv.conf file. We just run the basic HP network no fancy cards or stuff. We do not use DHCP, I just wonder if I need anything else beside those two files.

Hi,

For network, take print out or soft copy of these items too:

1) /etc/rc.config.d/netconf (network config file)
2) netstat -ins
3) ifconfig lan0 ( repeat if more than one card)
4) /etc/services
5) /etc/inetd.conf
6) /etc/rc.config.d/nfsconf ( NFS file)
7) nslookup
8) ioscan -fnC lan

HTH,

Hi,

Yip,

the /etc/rc.config.d/netconf and /etc/nsswitch.conf and /etc/inetd.conf files can be off use.

Hi
The use of set_parms command is the easiestway to configure hostname and lan, dont forget /etc/nsswitch.conf if you are using DNS...

Good luck

James,

You definitely want the /etc/rc.config.d/netconf file. Contains important config info.

Hi,

Again see this document- Checklist for Update to 11.0:

HTH,

Since you say you are not big in the network department, before you do your upgrade, look at
netstat -r
and verify that you have a default route assigned and note its ip address.

Now
ping ipadressofDefaultGateway

and verify that it works before you do your upgrade. No point in tearing your hair out looking for an 11.0 problem when your network is down.

If you do not have a default that's OK. Find an ip address of something on your local LAN and ping it instead. DO NOT try to ping yourself as that proves nothing.

Now look at /etc/rc.config.d/netconf and find your IP address and net mask. You will need these handy (along with the gateway) when you do your install. You will also be asked for the hostname. It's probably best to keep the same name so as not to upset your hosts files on other computers. If you dont' know its current name do
uname -a. The name is the second field.

Hi please look at the check list.

If you are running NIS on your system the restore following files from backup

/etc/rc.config.d/namesvrs
/etc/nsswitch.conf
/etc/hosts
also the NIS map files

If running DNS
/etc/name*
/etc/named.data directory
/etc/resolv.conf

If NFS is running :

/etc/exports
/etc/rc.config.d/nfsconf

In general you will need following
/etc/netconf
/etc/hosts
/etc/resolv.conf
/etc/hosts.equiv
/etc/nsswitch.conf
/etc/namesvrs
/etc/services

MAke sure you have noted the links for different scripts under /sbin/init.d directory.

If you have not restored follwing, please do so.

/etc/passwd
/etc/group
/etc/profile/etc/shutdown.allow

This is enough as per my view.

Thanks,
