AUTOFS not working in NIS

Hi All,

I have all CENTOS 5.5 boxes.

This is my scenario.

Code:

192.168.1.10    box1.test.com    NIS and NFS SERVER

192.168.1.20    box1.test.com    NIS CLIENT / NFS CLIENT (AUTOFS)

These are NFS exports on box1 which I am trying to Automount on box2

Code:

[root@box2 ~]# showmount -e 192.168.1.10

Export list for 192.168.1.10:

/home            *

/nishome/network1 *

I have certain users' home dir. on /home and some users' home dir of network1 in /nishome/network1

Home dirs. under /home are automounting perfectly BUT
home dirs. under /nishome/network1 are not automounting.

Code:

[root@box2 ~]# hostname

box2.example.com



[root@box2 ~]# nisdomainname

ABCD



[root@box2 ~]# getent passwd | tail -4

vicky:$1$132.5HcH$sq6UJxNpFrcUh8l1FAHlV0:502:502::/home/vicky:/bin/bash

vikas:$1$2j6jtgf5$eliQcjFhCbqi.hdZCqaEY/:501:501::/home/vikas:/bin/bash

nisuser1:$1$jejlU3CC$GYEhZl8LHGdAUqn7FXaPu0:800:800::/nishome/network1/nisuser1:/bin/bash

nisuser2:$1$hBQOEA.S$Z3.glka5imAtE6vyJxMBM1:801:801::/nishome/network1/nisuser2:/bin/bash

These are my autofs config files:

Code:

[root@box2 ~]# grep home /etc/auto.master

/home  /etc/auto.home

/nishome /etc/auto.nishome



[root@box2 ~]#  cat /etc/auto.home

*      -fstype=nfs 192.168.1.10:/home/&



[root@box2 ~]#  cat /etc/auto.nishome

*      -fstype=nfs 192.168.1.10:/nishome/network1/&

Now, this is my problem.

Quote:

[root@box2 ~]# su - vikas
[vikas@box2 ~]$ pwd
/home/vikas
[vikas@box2 ~]$ exit
logout
[root@box2 ~]# su - vicky
[vicky@box2 ~]$ exit
logout
[root@box2 ~]# su - nisuser1

logout
[root@box2 ~]# su - nisuser2
su: warning: cannot change directory to /nishome/network1/nisuser2: No such file or directory
-bash-3.2$ exit
logout

Manual mounting goes fine.

Code:

[root@box2 ~]# mount -t nfs 192.168.1.10:/nishome/network1 /nishome



[root@box2 ~]# df -hP /nishome

Filesystem            Size  Used Avail Use% Mounted on

192.168.1.10:/nishome/network1  4.8G  3.7G  857M  82% /nishome

Any help, how to dig it further. I worked fairly on NIS, but never used any other dir. other than /home for automounting.

Apologies, if this post became a little longer. Actually, I have tried to give the maximum information.

Hi vikas027
assuming oyur nis configuration is correct, can you change passwd entries in box2

Code:

nisuser1:$1$jejlU3CC$GYEhZl8LHGdAUqn7FXaPu0:800:800::/nishome/network1/nisuser1:/bin/bash

nisuser2:$1$hBQOEA.S$Z3.glka5imAtE6vyJxMBM1:801:801::/nishome/network1/nisuser2:/bin/bash

Code:

nisuser1:$1$jejlU3CC$GYEhZl8LHGdAUqn7FXaPu0:800:800::/nishome/nisuser1:/bin/bash

nisuser2:$1$hBQOEA.S$Z3.glka5imAtE6vyJxMBM1:801:801::/nishome/nisuser2:/bin/bash

Hi Fortez,

Yes, I can change passwords sitting on NIS cients.

Code:

[root@box2 ~]# su - nisuser1

su: warning: cannot change directory to /nishome/network1/nisuser1: No such file or directory

-bash-3.2$

-bash-3.2$ passwd

Changing password for user nisuser1.

Changing password for nisuser1

(current) UNIX password:

New UNIX password:

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

-bash-3.2$

Hi vikas027
in a nis architecture password is changed with yppasswd...
However i mean not to change pasword, but to change home directory from /nishome/network1/nisuser1(2) to /nishome/nisuser1(2)

This is what I do not want to do. Actually, in RHCE exam there used to be a question (around 2 years ago) to configure autofs such that /nishome/station1/nisuser1 home directory which is on NIS server gets mounted to local system at /nishome/nisuser1 (not /nishome/station1/nisuser1)

I was able to it there, but could not configure their NIS setup at my place.

I think you are confusing nis configuration and nfs configuration
I do not understand your RHCE reference, but i think that your nfs configuration is wrong independently from nis use and RHCE exam experience
If you read your nfs maps

[root@box2 ~]# grep home /etc/auto.master
/home /etc/auto.home
/nishome /etc/auto.nishome

[root@box2 ~]# cat /etc/auto.home
* -fstype=nfs 192.168.1.10:/home/&

[root@box2 ~]# cat /etc/auto.nishome
* -fstype=nfs 192.168.1.10:/nishome/network1/&

you see that :
- when on client you type cd /home/vikas , you are mounting /home/vikas directoty that is on nfs server
- when on client you type cd /nishome/network1/nisuser1 , you are mounting /nishome/network1/network1/nisuser1 directoty on nfs server; this directory with double network1 do not exist on nfs server

See I want this, which works well with NFS

Code:

[root@box2 ~]# mount -t nfs 192.168.1.10:/nishome/network1 /nishome



[root@box2 ~]# df -hP /nishome

192.168.1.10:/nishome/network1  4.8G  3.7G  857M  82% /nishome

Afer this manual mount, can you make

Quote:

[root@box2 ~]# su - nisuser1

withou error?

No.

Code:

[root@box2 ~]# mount -t nfs 192.168.1.10:/nishome/network1 /nishome

It confirms that you have to change home directory in /etc/passwd file as i have suggested before....

So:
1) if you want that /nishome/nisuser1/ on client matchs /nishome/network1/nisuser1 on nfs server your autofs maps are correct and you have to change your /etc/passwd file in

Quote:

nisuser1:$1$jejlU3CC$GYEhZl8LHGdAUqn7FXaPu0:800:800::/nishome/nisuser1:/bin/bash
nisuser2:$1$hBQOEA.S$Z3.glka5imAtE6vyJxMBM1:801:801::/nishome/nisuser2:/bin/bash

in way that when you type cd /nishome/nisuser1/ on your client, you are using /nishome/network1/nisuser1 on nfs server,

2) if you want that /nishome/network1/nisuser1 on client matchs exactly /nishome/network1/nisuser1 on nfs server your /etc/passwd file is correct but you have to create network1 directory under nishome on client and to change your auto.master map in

Quote:

/home /etc/auto.home
/nishome/network1/ /etc/auto.nishome

Because you have a nis architecure, changes in /etc/passwd or /etc/auto.master have to made on nis server. From these files o nis server then you rebuild corresponding nis maps.

Hi Fortez,

I do agree about your points, but I am still confused how RHCE server builders did this.

Assuming you have clear nfs configuration as it was without nis, please can you post:

- nsswitch.conf on nis/nfs client
- auto.master,auto.home,auto.nishome on nis/nfs server
- the output of ls -l /var/yp/your_nis_domain on nis/nfs server

Hi Fortez,

I has same problem cited above.

My nsswitch.conf is:

Code:

#

# /etc/nsswitch.conf

#

# An example Name Service Switch config file. This file should be

# sorted with the most-used services at the beginning.

#

# The entry '[NOTFOUND=return]' means that the search for an

# entry should stop if the search in the previous entry turned

# up nothing. Note that if the search failed due to some other reason

# (like no NIS server responding) then the search continues with the

# next entry.

#

# Valid entries include:

#

#        nisplus                        Use NIS+ (NIS version 3)

#        nis                        Use NIS (NIS version 2), also called YP

#        dns                        Use DNS (Domain Name Service)

#        files                        Use the local files

#        db                        Use the local database (.db) files

#        compat                        Use NIS on compat mode

#        hesiod                        Use Hesiod for user lookups

#        [NOTFOUND=return]        Stop searching if not found so far

#



# To use db, put the "db" in front of "files" for entries you want to be

# looked up first in the databases

#

# Example:

#passwd:    db files nisplus nis

#shadow:    db files nisplus nis

#group:    db files nisplus nis



passwd:    files nis

shadow:    files nis

group:      files nis

initgroups: files



#hosts:    db files nisplus nis dns

hosts:      files nis dns myhostname



# Example - obey only what nisplus tells us...

#services:  nisplus [NOTFOUND=return] files

#networks:  nisplus [NOTFOUND=return] files

#protocols:  nisplus [NOTFOUND=return] files

#rpc:        nisplus [NOTFOUND=return] files

#ethers:    nisplus [NOTFOUND=return] files

#netmasks:  nisplus [NOTFOUND=return] files    



bootparams: nisplus [NOTFOUND=return] files



ethers:    files

netmasks:  files

networks:  files

protocols:  files

rpc:        files

services:  files



netgroup:  nisplus



publickey:  nisplus



automount:  files nisplus

aliases:    files nisplus

My auto.home:

Code:

* -fstype=nfs, rw, nolock 10.50.2.154:/export/home/&

My auto.master:

Code:

/home /etc/auto.home
