You realise of course this has very little to do with the original 
question. (-:

Take the tapes, and prefereably the drive, to the second machine, 
even the controller card if need be, and install them to the point 
of being operational.   Or make sure the network is transparent so 
you can access the drive from a shell on the target machine.  I'm 
not that great on the networking stuff, so I'd move the drive and 
controller card.  But thats just *my* personal preferences.

Make sure you have the following tools available on the second 
machine.
mt
dd
tar (or (shudder) dump)
gzip

The files on the tape are laid out like this
amanda tape ID header (32k)
{
        amanda - tar identifying header, may be 32k, I'm not sure
        tar'd file represesnting one DLE
}
repeat the {} contents till last DLE is done, at which point an 
attempted read of the next header will get you an EOT error.

then

all this assumes the use of the non-rewinding tape device alias.

1. rewind tape
2. dd if=tapedev bs=32k  # will show you the tapes name
3. dd if=tapedev bs=32k  # will tell you onscreen what the next file 
on the tape is, and whether or not you need to pipe it thru gzip, 
showing you the actual command line to use.

At this point, go make the target dir for this particular file, and 
cd to it.

4. Follow the directions you got from step 3
5. repeat from step 3 until out of data on that tape
6. eject tape and insert 2nd one
7. repeat from 1 to 5.
8. move data to where you want it if the recovery wasn't pointed 
there in the first place.

A simple concept, but lots of work.  No mistakes allowed unless you 
keep track of the file/DLE count so the tape can be rewound, and 
then repositioned to the proper starting location with an "mt -f 
device fsf filenumber"  where device is say /dev/nst0 (you MUST use 
the non-rewinding device for this) and where filenumber might be 26 
if thats where you lost track of all the trees in this here forest.
