RPC.YPPASSWDD(8,C) AIX Commands Reference RPC.YPPASSWDD(8,C) ------------------------------------------------------------------------------- rpc.yppasswdd PURPOSE Server for modifying NIS password file. SYNTAX +----------------+ /etc/rpc.yppasswdd --- file ---| |---| +- -m --- arg ---+ ^ | +-------+ DESCRIPTION The rpc.yppasswdd command is an NIS server that handles password change requests from yppasswd. It changes a password entry in file, which is assumed to be in the format of passwd. An entry in file will only be changed if the password presented by yppasswd matches the encrypted password of that entry. This server is not run by default, nor can it be started up from inetd. If it is desired to enable remote password updating for NIS, an entry for rpc.yppasswdd should be put in the /etc/rc.nfs file of the host serving as the master for the NIS passwd file of the current NIS domain. Notes: 1. This can be accomplished by uncommenting (removing the leading "#" characters from) lines found in the default /etc/rc.nfs file. 2. If the NIS master host is a site in a TCF cluster, rpc.yppasswdd should only be started on that one host in the cluster which is the master. This is already accounted for in /etc/rc.nfs by a check for the existence of the file /local/yp//MASTER. You can either choose to make the NIS password input file be /etc/passwd or select another input file of the same format. You would select an alternate password input file, for instance, if you wanted to allow additional users to log on to the master NIS host beyond those permitted to log on to other hosts in your NIS domain. To select an alternate NIS password input file, for example /etc/yp/passwd, you should start up /etc/rpc.yppasswdd as follows: Processed July 12, 1991 RPC.YPPASSWDD(8,C) 1 RPC.YPPASSWDD(8,C) AIX Commands Reference RPC.YPPASSWDD(8,C) /etc/rpc.yppasswdd /etc/yp/passwd -m passwd DIR=/etc/yp FLAG -m After file is modified, a make will be performed in /etc/yp.
