>Description:

There are several problems with /etc/rmt:

open modes are not masked with 3 to make sure that no bits are used that
differ between different OS.

The answer for the 'S' command (get status) limits the size of the answer to 24 bytes.
This is not a secure decision:
	the size of the original structure has been 1 bytes

	All rmt clients - except the one found in star-1.3a7 and newer die from getting
	too much data.

	If you do not count Linux and byte order problems only the first two entries
	in struct mtget are binary portable between systems.

>How-To-Repeat:

	

>Fix:

	Try to switch to the rmt server that comes with star-1.3a7 and newer.
	NOTE: star-1.3a7 will be released in a few days.

	Also make sure that the FreeBSD rmt clients (e.g. dump ...) do not die
	from getting too much data with the get status command.
	The correct method would be to fetch as much data as available and only
	copy as much as the local struct mtget holds.
