       conserver.passwd - user access information for conserver(8)




       The  conserver.passwd file is the user authentication and authorization
       file for conserver(8).  Upon each incoming client connection, conserver
       opens  and  reads  the conserver.passwd file, so edits to the file take
       effect immediately.  It reads only until the first username match.

       Blank lines and  comment  lines  (those  beginning  with  a  ‘‘#’’  and
       optional  leading whitespace) are ignored.  Non-ignored lines beginning
       with whitespace are considered  continuations  of  the  previous  line.
       This  allows  you to span one logical line over many physical lines and
       insert comments wherever appropriate.

       Each logical line consists of two colon-separated fields.  Leading  and
       trailing white space in each field is ignored.

              the  login  name of the authorized user, or the string ‘‘*any*’’
              to match any user.  This is compared against the  name  sent  by
              the  console  client,  based either on the user’s identity or on
              the -l option.  Since conserver only  uses  the  first  username
              match, a ‘‘*any*’’ entry will apply to any user without an entry
              earlier in the file.

              the encrypted password, or the string ‘‘*passwd*’’  to  indicate
              that  conserver should look up the user’s password in the system
              passwd (or shadow) database.  If PAM support  has  been  enabled
              (--with-pam),  PAM  lookups  will  be done instead of passwd (or
              shadow) lookups (you may need to edit  /etc/pam.conf  or  create
              /etc/pam.d/conserver).    If   this  field  is  empty,  password
              checking is bypassed for this user.


       mary:r71mXjfALB5Ak      Mary uses the password specified above; it does
                               not  matter  whether  she  has  a  login on the
                               conserver host.

       fred:*passwd*           Fred may connect only with  his  regular  login
                               password on the conserver host.

       bozo:*                  Bozo is only allowed to access a console if his
                               password isn’t used (since it’s invalid)  which
                               means he needs to come from a trusted host.

       *any*:*passwd*          Anyone  not  listed  above  uses  their regular
                               login and password.


       console(1),, conserver(8)


       There is currently no way provided by the conserver package to generate
       the  encrypted  password  strings  besides copying them from the system
       passwd database or running  crypt(3)  via  C  or  perl  or  some  other
       language that supports it.
