Try checking the debug files on m254.gc.cuny.edu (default is in /tmp/amanda)
and see if there is more information there.
One possibility is a firewall blocking the estimate response, since the
response usually occurs long after most firewall connection timeouts.
Look for 'no response' errors in the client debg files.
Just so your backups don't hang forever you might want to make sure your
etimout isn't set larger than necessary. Don't forget it is multiplied by
the number of DLEs on the host, so a setting of 1 hour on your m254 host
could result in a wait of up to 7 hours. You can use a negative number
it will be the per host timeout instead of per DLE.
