NIS server migration

[Susi]

Currently, an HP-UX 10.2 box is the NIS server in our network. We want to switch, and make an HP-UX 11.0 machine the NIS master server and another HP-UX 11.0 the slave server. How do I 'unconfigure' the current server? How do I configure the new master and slave servers? Could I just copy the current NIS source files to the new master server? Are there any issues because of SUN and RedHat Linux clients in our network?

At your new NIS master server do the following commands:
domainname [domainname]
ypinit -m (follow prompts)
edit /etc/rc.config.d/namesvrs
change NIS_MASTER_SERVER variable to 1 and add the domainname. If you are going to use a NIS slave you should also set the YPSET_ADDRESS to the master's IP in the namesvrs file.

At your new NIS slave:
domainname [domainname]
ypinit -s [master_server hostname]
edit /etc/rc.config.d/namesvrs
change NIS_SLAVE_SERVER to 1
change appropriate domainname and change YPSET_ADDRESS to slave server's IP.

In the /var/yp directory there are some pretty good predefined scripts which could be entered into cron to allow the slave server to update its NIS tables on a regular basis.


To disable your original NIS master:
run /sbin/init.d/nis.server stop
edit /etc/rc.config.d/namesvrs
change NIS_MASTER_SERVER to 0

Make sure your new NIS master has all the appropriate updates to things like /etc/hosts /etc/passwd /etc/group /etc/services, etc.

Good Luck.

Hi
before doing ypinit in master server make sure that /ect/passwd, /etc/hosts, /etc/netgroups, /etc/mail/alias etc are uptodate, you can do a ypcat and get the files uptdated. thereafter you can do the ypinit
