The backup listhosts command displays the Backup Database record of the
port offset numbers defined for Tape Coordinator machines. A Tape
Coordinator must have an entry in the list to be available for backup
The existence of an entry does not necessarily indicate that the Tape
Coordinator process (butc) is currently running at that port offset. To

Constructs a server ticket using a key from the local

The Tape Coordinator's port offset number.
The Tape Coordinators appear in the order in which they were added to the
The following example shows the result of the command in the ABC
% backup listhosts
Host backup1.abc.com, port offset 0
Host backup1.abc.com, port offset 1
Host backup3.abc.com, port offset 4
Host backup2.abc.com, port offset 3
The issuer must be listed in the /etc/openafs/server/UserList file on every
machine where the Backup Server is running, or must be logged onto a
server machine as the local superuser "root" if the -localauth flag is
