NIS Problems

[Barry Lake]

Hi, I have inherited some HP-UX 11.0 systems that were left in terrible disarray. These systems are running NIS and/or NIS+, and I have no experience with these products, unfortunately. My immediate problem is that I need to gain access to the data in the passwd.org_dir file. When I try doing "niscat passwd.org_dir" while logged in as root with my current directory set to passwd.org_dir's parent directory, niscat just hangs. It gives no output, and it never returns. I have to hit ctrl-c to get out. Can someone please give me some hints as to what I need to do to get this to work? Thanks!

Shalom,

First step in an ugly process.

See if the nis daemons are running.

The start/stop scrips are in /sbin/init.d

They start with nis, there is a server or client program.

stop the client
stop the server
start the server
start the client

Take a look at the config files in /etc/rc.config.d/namesvrs and see what the intent of the setup is.

Steven, thanks for the reply. I found the following:

1) On one of the three servers the NIS_DOMAIN setting in the /etc/rc.config.d/namesvrs config file was different from the other two. I fixed that so all three servers have the same NIS_DOMAIN.

2) On all three servers I confirmed that the namesvrs config file has

NIS_MASTER_SERVER=0
NIS_SLAVE_SERVER=0
NIS_CLIENT=0
NISPLUS_SERVER=1
NISPLUS_CLIENT=1

3) ps -ef on each of the three servers showed a different set of demons running. One had rpc.nispasswdd, another had rpc.nisd and the third had nis_cachemgr. Also a couple of them had keyserv.

4) On all three servers I stopped the demons with

# /sbin/init.d/nisplus.client stop
# /sbin/init.d/nisplus.server stop

5) On all three servers I started the demons with

# /sbin/init.d/nisplus.server start
# /sbin/init.d/nisplus.client start

6) On one of the three servers ps -ef shows:

# ps -ef | grep nis
root 23889 1 210 15:01:40 ? 10:03 /usr/sbin/nis_cachemgr
root 23852 1 20 15:00:26 ? 1:52 /usr/sbin/rpc.nisd

On another I see:

# ps -ef | grep nis
root 20418 1 205 14:52:03 ? 9:55 /usr/sbin/nis_cachemgr
root 20387 1 0 14:51:01 ? 0:00 /usr/sbin/rpc.nispasswdd
root 20382 1 101 14:51:01 ? 7:28 /usr/sbin/rpc.nisd

On the third server ps -ef hangs now (didn't before) and never returns without ctrl-c. Incidentally, that's the same server where I changed the NIS_DOMAIN to match the other two.

7) On all three servers "niscat passwd.org_dir" still hangs.

Any more suggestions? :)

TIA,
Barry.

For the record, I did finally manage to gain access to the data in the passwd.org_dir file by adjusting the /etc/nsswitch.conf file. It originally had records in it like:

passwd: files
group: files
hosts: files
services: files

I changed it to look like:

passwd: files nisplus
group: files nisplus
hosts: nisplus [NOTFOUND=return] files
services: nisplus [NOTFOUND=return] files

Then I stopped and started the NIS+ servers again, and voila, niscat now works, and doesn't hang!

Thanks again to SEP, whose excellent suggestions got me going on the right track.

Regards,
Barry.

Hi,
Can you test an "nisping -C" on server, nisls org_dir on host,niscat -o paswwd.org_dir on the server ? Give me the return
