UUCP truncates system names to seven characters
By default, UUCP truncates system names to seven
characters to ensure compatibility with all versions of
UUCP. Although disabling this feature is not
recommended, it can be done.
In the file /usr/lib/uucp/Permissions, add the variable MYNAME=name to each entry in this file, where name is the actual system name that contains more than seven characters. Also, add a new entry in /usr/lib/uucp/Permissions as follows:
MACHINE=OTHER \ READ=/usr/spool/uucppublic:/usr/tmp \ WRITE=/usr/spool/uucpppublic:/usr/tmp \ COMMANDS=rmail:rnews:uucp \ SENDFILES=yes REQUEST=yes \ MYNAME=namewhere name is the actual system name.
The MYNAME variable supersedes the truncated name. This procedure should be done on every machine in the UUCP network that has a name more than seven characters long.
