sharePrinters(1M)

NAME
     sharePrinters - share local printers with remote hosts.

SYNOPSIS
     /usr/sysadm/privbin/sharePrinters -all
     /usr/sysadm/privbin/sharePrinters -hosts host-name [ ... ]

DESCRIPTION
     sharePrinters is a privileged command that enables the sharing of local
     printers by editing the .rhosts file for the "lp" user account.  When
     "lp" on one IRIS can rlogin(1C) to the "lp" account on another IRIS, the
     first IRIS can then forward print jobs to the second IRIS.

     When the -all option is used, /var/spool/lp/.rhosts is edited to contain
     one line with the single character '+'.  This enables remote access for
     all hosts.

     When the -hosts option is used, /var/spool/lp/.rhosts is edited to
     contain one line for each host specified on the command line.  The
     canonical host name is used for each host specified.  Additionally, if
     the "lp" account has no password, '*' is written into the password field
     for the "lp" account in /etc/passwd.  This disables logins to the "lp"
     account from machines that are not mentioned in /var/spool/lp/.rhosts (or
     /etc/hosts.equiv; see below). This restricts remote access to those hosts
     specified on the sharePrinters command line.

CAVEATS
     sharePrinters -hosts will not succeed in restricting access to the hosts
     passed in on the command line if one of the files /etc/hosts.equiv or
     /etc/hosts.lpd contains entries other than "localhost".  hosts named in
     either of these files will also be able to submit print jobs.
     sharePrinters detects these cases and issues warnings to the system
     administration log, /var/sysadm/salog.

     If one of the hosts passed to sharePrinters -hosts is also sharing
     printers, it is possible that unauthorized hosts can forward jobs through
     that host.

FILES
     /var/spool/lp/.rhosts     List of hosts which can rlogin to the lp
                               account.
     /etc/passwd               Database of user accounts.
     /etc/hosts.equiv          List of equivalent hosts.
     /etc/hosts.lpd            Remote access file for the bsd spooler,
                               lpd(1M).
