irix 6.5 nis problem
|
|
| Alexander Haas 2004-01-23, 5:02 pm |
| Hi!
We have little trouble to getting a nis client running properly on our
irix 6.5 machines (octane, indigo2, indy):
the nis server is a redhat 7.3 and is up and running, all other
clients (linux boxes, hp-ux 11, aix, solaris machines) have no
problems getting the desired data (passwd, group) from nis. all
network is up and running, the irix machines can reach (ping, telnet)
the server, and vice versa.
for the nis setup, we followed the insructions on
http://www.tu-darmstadt.de/hrz/unix...st_prot6_5.html (its a
german irix installing howto) with the following steps:
chkconfig yp on
set correct nis domain name in /var/yp/ypdomain
added +:::::: to /etc/passwd
added +::: to /etc/group
changed the passwd and group line in /etc/nsswitch.conf to: files nis
(we also tried: nis files; host is resolved via file dns)
we rebooted the machine to activate nis (we also tried killall -HUP
nsd)
so, we thought everthing should be fine, but when a nis user tries to
login, we just receive:
unknown user id: name_of_nis_user
does anybody know whats wrong??
each hint is welcome!
regards

nis dns files ?

looks like what happens when thereīs no /etc/passwd.nis file on the yp
server. Since your server runs no IRIX I canīt say whatīs going wrong.
I tried the thing vice versa once - LINUX box slave and IRIX server.
That didnīt work from scratch either (some software missing on slave),

I don't know what's wrong (of course  , but you can do a bit more
debuging:
* does "ypinit" give you the name of the NIS server?
* does "ypcat passwd" show the server's passwd map?
* does "finger find the user? if not, that's a nsswitch problem
In general, I'd first use ypinit(1M) to setup the machine as NIS client
("ypinit -c"), not touch /etc/passwd or /etc/group, and only add nis to
the "passwd" and "group" line in /etc/nsswitch.conf. Make sure shell and
home-dir from the passwd file exist so the user can log in.

well, I dont know if ypinit gives me the name of the server, but when
I use ypinit to set up the nis database, I have to enter the server
name; and when I call ypinit after this, it says
Destination directory, /var/ns/domains/name_of_our_nis_domain, already
exists.
Can we remove it? [y/n]
where name_of_our_nis_domain ist the right name of the domain which is
hosted by the server. So I think this should be ok.

> * does "ypcat passwd" show the server's passwd map?
yes. It lists all of the expected nis users (also does ypcat group)
quote:

no :-((
If its a nsswitch problem, I cant see it. We use the following
nsswitch.conf:
#automount(dynamic): nis(nis_enumerate_key)
#bootparams: files nis
capability: files
clearance: files
ethers: files
group: nis files
hosts: dns files
mac: files
mail(null_extend_key): ndbm(file=/etc/aliases)
netgroup: nis
#netid.byname: nis
networks: files
#passwd: files(compat) [notfound=return] nis
passwd nis files
protocols: files
rpc: files
services: files
shadow(mode=0700): files
#ypservers: nis
jlimits: mdbm nis
I think the passwd and group line are ok, but I am not sure about the
ypservers line: I also tried
ypservers nis
and
ypservers files nis
(followed by a killall -HUP nsd)
but nothing changes
Can you tell me whats wrong?

Are you sure that I should not touch /etc/passwd and /etc/group? I
think I have to add + (or +::::: there??

PS: I found some postings that mention that Linux NIS server -> SGI
client may have crypt problems. Does anybody know something about
this?
(we do not use md5 passwords or shadowing)

what does this mean?
I cant find this in man 4 passwd.
I tried out, but it doesnt change the behaviour ...quote:

no , we do not use nis to share hosts, all names are resolved by dns.

but ypcat passwd on the slave (SGI) lists the expected users, and so
does ypcat group. so I think the server sends the right data and the
sgi receives it - but it does not find the way to the login command
:-(
Any other ideas?

That is only used if you have files(compat).

OTOH, as it's missing the [notfound=return], that *should* be looking
up anything not found in /etc/passwd, regardless of the "+" lines in
/etc/passwd.
As for the nsswitch.conf excerpt:
#passwd: files(compat) [notfound=return] nis
passwd nis files
One line is missing a colon.

i just commented the passwd nis files out and made the original
passwd: files(compat) [notfound=return] nis
active, now it works :-))))
I think I changed this line during a time where the nis client itself
was set up wrong (thx to walter for leading me to the right way), but
caused by this wrong line in nsswitch.conf the login process was not
able to access the nis data.
thx to all who helped me solving this problem!
