node.perms
NODE.PERMS(5) Linux Programmer's Manual NODE.PERMS(5) 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 follow- ing 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. FILES
