[lug] Tape backup error

[Jason Strnad]

The man page indicates that use of the hostname argument causes tar 
(gnu tar anyway) to use 'rmt' to perform the network operations.  As an 
'r' utility, i'd expect you it would use the same facilities you might 
expect rsh (and similar) to use.  And hopefully those facilities have 
been disabled for security reasons. <grin>
