Summary:	Change (SunOS) NIS passwd error
Product:	Base System	Reporter:	wkwu <wkwu>

Description wkwu 2000-10-25 07:50:00 UTC

We have to using SunOS-4.1.3 yp_server.
patch for /usr/src/usr.bin/passwd/yp_passwd.c
line: 83
-       pw = (struct passwd *)&yp_password;
+       pw = getpwuid(uid); 

It worked well before. Now when changing passwd:
Changing NIS password for wkwu on nis-server.
Old Password: 
New password:
Retype new password:
passwd: failed to change NIS password: RPC: Server can't decode arguments

I have traced some source. But no idea ...

Fix: 

No idea.
How-To-Repeat: 
Using FreeBSD as yp_client to bind SunOS-4.1.3 yp_server.

This very problem occurs also on more up-to-date systems, that is:

 NIS-Server: Solaris 2.6 /SPARC
 NIS-Client: FreeBSD 4.2 /i386

 Changing NIS password for user on NIS-server.
 Old Password:
 New password:
 Retype new password:
 passwd: failed to change NIS password: RPC: Server can't decode arguments

Snoop output on the NIS server:

 client -> server  PORTMAP C GETPORT prog=100009 (NISPASSWD) vers=1 proto=UDP
 server -> client  PORTMAP R GETPORT port=819
 client -> server  NISPASSWD C
 server -> client  RPC R (#196) XID=861861090 Garbage arguments


It impossible for users to change their passwords. This PR should
therefore be updated from "Serious" to "Critical"!

Does this still occur on more recent releases? If so, a tcpdump 
including the full packet contents (-s 1600 -X) of the failing 
operation would be helpful.

Feedback timeout. 

Additionally, I can confirm that with a June 1st stable NIS client 
and a Solaris 8 NIS server, yppasswd works fine, with the proviso 
that you must be using the des password format for your users; this 
is understandable in my opinion.
