ypinit/ypxfr always give "RPC: Program not registered" error (resend)

[David Trusty]

Hi,

[For some reason, my previous post is unreachable...]

I cannot get our 11.0 server to initialize
NIS. The master is a Linux machine.

Here are the diagnostics:
# ypinit -s genetics.swmed.edu

Hi David,

1) May I know, in which flavour of Linux u have tried.?

Is that NIS/NIS+?

2) morpheus.swmed.edu -- May I know what is this m/c?? (Is this same systems/other Master NIS)

check the entries in /etc/rc.config.d/namesvrs,
----
NIS_MASTER_SERVER=0
NIS_SLAVE_SERVER=1
NIS_CLIENT=1
NIS_DOMAIN="genetics-nis"
-------

3) Above NIS_DOMAIN entry assumed - the domain in which ur NIS Master Server is laying.

On the Master server, If u get output for
rpcinfo -p
then ur rpc port has been binded for nis server. (And also check 100007 port has ypbind.)

4) Restart the services (/sbin/init.d/nis.server, /sbin/init.d/nis.client)

**) If these are not solving problem, then could u please give the output of the following on the master server
*) rpcinfo
*) ypwhich
*) domainname

All the best

Hi,

It seems to me you forgot to add subnet of this machine to /var/yp/securenets file on your NIS-master machine.

HTH

[David Trusty]

Hi,

Thanks for responding. Here is the info you
requested:

1. The master is running Redhat 9
2. The machine "morpheus.swmed.edu" is another
slave server -- a HPUX 11i machine (seems
to connect to the master just fine...)
The /etc/rc.config.d/namesvrs is as you
assumed.
3. Here is rpcinfo -p from the master:
[root@genetics yp]# rpcinfo -p

100007 1 tcp 992 ypbind
100009 1 udp 722 yppasswdd
4. ypwhich on the master gives the master's
IP address
5. domainname on the master gives "genetics-nis"

I have no /var/yp/securenets file. Here is
the documentation for it on the master:
"If the /var/yp/securenets file does not exist, ypserv will allow connections from
any host."

Any ideas?

Thanks!!

David

Hi

*) To confirm that NIS Master is working fine, run ypxfr on NIS another slave server - and check. If this is going thru' v may need to check only on new server which v r going to add...

*) Please check the /etc/rpc

ypxfrd 100069

has enabled, in NIS Master and slave. this could be the possible cause that u might be getting ypxfr: RPC Program not registered.
I suspect this could be the problem, since the rpcinfo -p didnt shown that ypxfrd is running on the port 100069.

*) There could be another possiblity, the ypservers entry may not have new slave server IP.
To do that,
o) # cd /var/yp/domainname
o) # makedbm -u ypservers >/tmp/temp_file
o) Add the NIS Slave server name into that file
o) # makedbm /tmp/temp_file ypservers
o) To confirm that, #makedbm -u ypservers

On New server.
# cd /var/yp
# /usr/sbin/ypinit -s genetics.swmed.edu

Hope these all documents will help you.

ALL THE BEST!

Hi,

I think I found the problem, and it looks like
it is a bug in the ypxfr code.

Look at this system call (tusc) trace of
ypxfr:
...
stat("/var/yp/genetics-nis/passwd.byname.dir", 0x7aff1904) ................................ ERR#2 ENOENT
stat("/usr/local/tmp/AAAa06268.dir", 0x7aff2584) .......................................... = 0
stat("/usr/local/tmp/AAAa06268.pag", 0x7aff2584) .......................................... = 0
rename("/usr/local/tmp/AAAa06268.pag", "/var/yp/genetics-nis/passwd.byname.pag") .......... ERR#18 EXDEV


As you can see, the NIS file is transferred
to the slave server, but the slave server
tries to rename the temp file into the
/var/yp file system and gets an error.

Do you concur? Any ideas on how to fix it?

Thanks,

David

[Dave Johnson_1]

my guess is the direcory /var/adm/genetics-nis does not exist. ENOENT is defined as:
[ENOENT] No such file or directory. This error occurs when a file name is specified and the file should exist but does not, or when one of the directories in a path name does not exist. It also occurs with msgget(), semget(), and shmget() when key does not refer to any object and the IPC_CREAT flag is not set.

while EXDEV is defined as:
[EXDEV] Cross-device link. A link to a file on another device was attempted.

If it does exist what is the output of:
ll -d /var/adm/genetics-nis
when run on the HP that is failing. Perhaps it is a permission problem.

Later

Hi,

I found the cause. The problem is that there
was an environment variable (TMPDIR) set
to /usr/local/bin.

When I removed that variable, it works.

Thanks for helping with this problem!!

That error indicates that the source and destination for the rename() system call are not on the same filesystem.

[A. Clay Stephenson]

Ooops, I hit [Submit] too quickly.

Normally, when rename() fails with EXDEV, the code would then try what would amount to a cp command followed by a rm. It's not done like this in C but the net effect is a cp and a rm or simply a mv.

In summary, this error is probably not significant because there should be a fallback operation if the easy method (rename) fails.
