- NAME
- UULIB:Security
-
- SYNOPSIS
- -
-
- DESCRIPTION
- The UULIB:Security file governs readability and writability
- of directories relative to remote uucp requests. The UUSPOOL:
- directory is always readable and writable. [NOTE: THIS IS A
- KNOW SECURITY LEAK, FUTURE RELEASES OF wUUCP WILL ADDRESS IT.]
-
- This prevents other nodes from examining or overwriting
- arbitrary files in your system.
-
- The UUCICO program, which does the actual work downloading
- and uploading files, will check remote-requested paths
- against this file by comparing inodes (DOS Locks) and not
- by name. The reason for this is simply that, on the Amiga,
- several different paths may refer to the same directory.
-
- Note that you need only specify the 'parent' directory and all
- sub directories will be allowed by default. So, for example,
- if you allow UUPUB: then people would be able to access UUPUB:-
- fubar, UUPUB:mydir/abcd, etc...
-
- Example file follows:
-
- uulib:Security
- ---------------------------------------8<-------------------------------------
- # This file is used by UUCICO to determine the validity of requests.
- #
- # The directories listed here are *allowed* directories for uucp
- # transfers. The permissions field lists permissions
- # r -readable
- # w -writable
- UUPUB: r
- UUPUBW: w
- --------------------------------------->8-------------------------------------
-
- In addition to what AmigaUUCP allows, with wUUCP you can specify
- directories to be accessable only by certain systems. Just create
- for any system you wish to have additional access permissions (you
- can't remove permissions this way yet) a file uulib:Security.SYSTEM.
- For example, if you want a system called `mcd' be able to access
- more directories, simply create uulib:Security.mcd, as shown below:
-
- uulib:Security.mcd
- ---------------------------------------8<-------------------------------------
- dh1:usr/spool/adsp rw
- dh1:usr/spool/mcd rw
- dh1:usr/spool/timebase rw
- samples: r
- libs: r
- devs: r
- uucp:c r
- --------------------------------------->8-------------------------------------
-
- uulib:Security is always checked first, thus the system mcd may
- fetch files from UUPUB: although that particular directory is
- not listed in uulib:Security.mcd.
-
- Hope that answers the FAQ `Access restrictions with wUUCP'รก;)
