NODE.PERMS(5)

NAME
node.perms - AWZNode 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 and FlexNet.

    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 AWZNode 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.

    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 and Flexnet connections. (See HiddenPorts command in node.conf(5).)
