NAME

       node.perms - LinuxNode permissions file.

DESCRIPTION

       Node.perms  file  is  read at program startup with the knowledge of users username (call),
       connection type (AX.25, NET/ROM, ROSE, TCP/IP), peers IP address  (for  TCP/IP)  and  port
       name (for AX.25). The first entry matching this information is taken and user is asked for
       password and given permissions according to it.

       The lines within node.perms must either be a comment line, which starts with a  #  in  the
       first column, or a permission entry in the following format, each field being delimited by
       white space:

              username type portname password permissions

       The field descriptions are:

       username      This is matched against users username (call) without SSID. An asterisk  (*)
                     matches any username.

       type          This is matched against the type of the connection to user.  Possible values
                     for this field are:

                     *      matches any type of connection.

                     ax25   matches users coming in with AX.25.

                     netrom matches users coming in with NET/ROM.

                     rose   matches users coming in with ROSE.

                     local  matches TCP/IP connections where users host is in "local" network  as
                            defined in node.conf(5).

                     ampr   matches   TCP/IP   connections   where   users  host  is  in  amprnet
                            (44.0.0.0/8).

                     inet   matches TCP/IP connections where users host  is  neither  in  "local"
                            network nor in amprnet.

                     host   matches users starting LinuxNode from shell.

       portname      If user is coming in with AX.25 this field is matched against the local port
                     name the user is coming in via. An asterisk (*) matches any port name.

       password      If the previous tree fields match and this field is not  a  single  asterisk
                     (*)  the  user is asked for a password. The password is then matched against
                     this field.

       permissions   This field represents a a bitmask of operations the user is permitted to do.
                     It is a sum of the values listed here:

                     1      permits logging in even if no other permissions are given.

                     2      permits outgoing AX.25 connects.

                     4      permits outgoing NET/ROM connects.

                     8      permits  telneting  to  hosts  in  the  "local" network as defined in
                            node.conf(5).

                     16     permits telneting to hosts in amprnet.

                     32     permits telneting to hosts neither in  the  "local"  network  nor  in
                            amprnet.

                     64     permits  using  hidden  ports  in  outgoing  AX.25 connections.  (See
                            HiddenPorts command in node.conf(5).)

                     128    permits outgoing ROSE connects.

                     256    The no-escape flag. Disables the escape mechanism for this user.
