NAME

       changeuser, wrkey, convkeys, printnetkey, status, auth.srv, guard.srv - maintain authentication databases

SYNOPSIS

       auth/changeuser [-np] user

       auth/wrkey

       auth/convkeys [-p] keyfile

       auth/printnetkey user

       auth/status user

       auth/auth.srv

       auth/guard.srv

DESCRIPTION

       These  administrative commands run only on the authentication server.  Changeuser manipulates an authentication database file system served
       by keyfs(4) and used by file servers.  There are two authentication databases, one holding information about Plan 9 accounts and one  hold-
       ing  SecureNet  keys.   A  user need not be installed in both databases but must be installed in the Plan 9 database to connect to a Plan 9
       service.

       Changeuser installs or changes user in an authentication database.  It does not install a user on a Plan 9 file server; see fs(8) for that.

       Option -p installs user in the Plan 9 database.	Changeuser asks twice for a password for the new user.	If the responses do not  match	or
       the password is too easy to guess the user is not installed.

       Option -n installs user in the SecureNet database and prints out a key for the SecureNet box.  The key is chosen by changeuser.

       If neither option -p or option -n is given, changeuser installs the user in the Plan 9 database.

       Changeuser  prompts for biographical information such as email address, user name, sponsor and department number and appends it to the file
       /adm/netkeys.who or /adm/keys.who.

       Wrkey prompts for a machine key, host owner, and host domain and stores them in local non-volatile RAM.

       Convkeys re-encrypts the key file keyfile.  Re-encryption is performed in place.  Without the -p option convkeys uses  the  key	stored	in
       /dev/keys  to decrypt the file, and encrypts it using the new key.  By default, convkeys prompts twice for the new password.  The -p forces
       convkeys to also prompt for the old password.  The format of keyfile is described in keyfs(4).

       Printnetkey displays the network key as it should be entered into the hand-held Securenet box.

       Status is a shell script that prints out everything known about a user and the user's key status.

       Auth.srv is the program, run only on the authentication server, that handles ticket requests on IL port 566.  It is started by an  incoming
       call  to  the  server  requesting  a  conversation ticket; its standard input and output are the network connection.  Auth.srv executes the
       authentication server's end of the appropriate protocol as described in auth(6).

       Guard.srv is similar.  It is called whenever a foreign (e.g. Unix) system wants to do a SecureNet challenge/response authentication.
