NAME

6       yppasswd - change your network password in the NIS database

SYNOPSIS

9       yppasswd [username]
10
11

DESCRIPTION

13       The  yppasswd utility changes the network password  associated with the
14       user username in the Network Information Service (NIS) database. If the
15       user  has done a keylogin(1), and a publickey/secretkey pair exists for
16       the user in the NIS publickey.byname map, yppasswd also re-encrypts the
17       secretkey with the new password. The NIS password may be different from
18       the local one on your own machine.
19
20
21       yppasswd prompts for the old  NIS password, and then for the  new  one.
22       You  must  type  in  the  old password correctly for the change to take
23       effect. The new password must be typed twice, to forestall mistakes.
24
25
26       New passwords must be at least four characters long, if they use a suf‐
27       ficiently  rich alphabet, and at least six characters long if monocase.
28       These rules are relaxed if you are insistent enough. Only the owner  of
29       the name or the super-user may change a password; superuser on the root
30       master will not be prompted for the old password, and does not need  to
31       follow password construction requirements.
32
33
34       The  NIS  password  daemon,  rpc.yppasswdd  must be running on your NIS
35       server in order for the new password to take effect.

WARNINGS

54       Even  after the user has successfully changed his or her password using
55       this command, the subsequent login(1) using the new  password  will  be
56       successful  only  if  the  user's  password  and  shadow information is
57       obtained  from  NIS.   See   getpwnam(3C),   getspnam(3C),   and   nss‐
58       witch.conf(4).

NOTES

61       The  use of yppasswd is discouraged, as it is now only a wrapper around
62       the passwd(1) command, which should be used  instead.  Using  passwd(1)
63       with the -r nis option (see NIS+(1)) will achieve the same results, and
64       will be consistent across all the different name services available.
65

BUGS

67       The update protocol passes all the information to the server in one RPC
68       call,  without  ever looking at it. Thus, if you type your old password
69       incorrectly, you will not be notified until after you have entered your
70       new password.
