USERFILE(5) File Formats Manual USERFILE(5) Name USERFILE - defines uucp security Syntax /usr/lib/uucp/USERFILE Description The utility uses the USERFILE to establish what access a remote system can have to the local system. An entry should exist for each sys- tem. If no entries exist for a particular system, the default entries are used. The entries for particular systems have the following format: login-name , node-name X # path-name login-name The name with which the remote system logs in. node-name The name of the remote node. X# The execution level for the remote system. The remote system can execute commands defined in the file that have an execution level less than or equal to the number #. path-name The remote system can access anything at the local system with this prefix. Two entries must also be provided for systems not otherwise listed: remote, X# path-name ... local, X# path-name ... These entries define the execution level and access pathnames for the local system and all remote systems not defined by specific entries. Examples remote, X1 /usr/spool/uucppublic local, X9 / max,systemY /usr/sources /usr/src/share max,systemZ X3 /usr In the above example, the node named systemY with the login name max has access to anything with the pathname prefixes and The node named systemZ with the login name max can execute commands defined in with an execution level of 3 or lower. It can access anything with the pathname prefix Any other remote systems can execute commands defined in with an execution level of 1 or 0. They can access anything with the pathname prefix of Users on the local system can execute any of the commands defined in and access anything on the system.
