access() — UTek 4319-4.0



ACCESS (dfs)(5N)        COMMAND REFERENCE        ACCESS (dfs)(5N)



NAME
     access - control remote access to local files.

SYNOPSIS
     /usr/lib/dfs/access

DESCRIPTION
     This file determines which users on which remote hosts may
     access the local file system.

     It is formatted as a host followed by an asterisk, for
     example:

          orca:*

     Lines beginning with '#' are comments.

     Remember that access determines if the daemon will attempt
     to execute the system call on behalf of the requesting host.
     However, the standard UTek owner-group-other protection
     scheme will ultimately determine the accessibility of the
     file by the remote process.

     /usr/lib/dfs/access is an ASCII file used to modify the
     access database; the actual aliasing information is placed
     into a binary format in the files /usr/lib/dfs/access.dir
     and /usr/lib/dfs/access.pag using the command
     /usr/lib/dfs/newdfs. These are dbm(3d) files.

     It is recommended that for editing access you use vidfs(8n).
     It will make a number of checks on the validity of the
     entries in the access file.  When setting up access keep two
     points in mind.  Users on the remote machine need not have
     login privileges nor do they need a home directory.  You can
     prevent them from logging on by setting their encrypted
     password to '*' or any other single letter (because no
     password encrypts to a single character).  Secondly, the
     local userid assigned to the remote user wishing to access
     the local file system must match the userid assigned to that
     remote user on the remote host.
