aolserver4-daemon 4.5.1-18.1 / postinst

#! /bin/sh -e
# postinst script for aolserver4
#
# see: dh_installdeb(1)
# summary of how this script can be called:
#        * <postinst> `configure' <most-recently-configured-version>
#        * <old-postinst> `abort-upgrade' <new version>
#        * <conflictor's-postinst> `abort-remove' `in-favour' <package>
#          <new-version>
#        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
#          <failed-install-package> <version> `removing'
#          <conflicting-package> <version>
# for details, see /usr/doc/packaging-manual/
#
# quoting from the policy:
#     Any necessary prompting should almost always be confined to the
#     post-installation script, and should be protected with a conditional
#     so that unnecessary prompting doesn't happen if a package's
#     installation fails and the `postinst' is called with `abort-upgrade',
#     `abort-remove' or `abort-deconfigure'.

# Control port -- nscp
#
# To enable:

# 1. Define an address and port to listen on. For security
#    reasons listening on any port other then 127.0.0.1 is
#    not recommended.
#
# 2. Decided whether or not you wish to enable features such
#    as password echoing at login time, and command logging.
#
# 3. Add a list of authorized users and passwords. The entires
#    take the following format:
#
#    <user>:<encryptedPassword>:
#
#    You can use the ns_crypt Tcl command to generate an encrypted
#    password. The ns_crypt command uses the same algorithm as the
#    Unix crypt(3) command. You could also use passwords from the
#    /etc/passwd file.
#
#    The first two characters of the password are the salt - they can be
#    anything since the salt is used to simply introduce disorder into
#    the encoding algorithm.
#
#    ns_crypt <key> <salt>
#    ns_crypt x t2
#
#    The configuration example below adds the user "nsadmin" with a
#    password of "x".
