You can't. But you can use ssh directly. Same authentication to remote host,
as well as same config setup. For simplicity, put options in config file,
either user's ~/.ssh/config or global ssh_config file if many users using this
script/connection. Maybe call it tapeserver2tape and redefine Host to just
tapeserver in that machine stanza, e.g.
Host tapeserver2tape
Hostname tapeserver
User operator
Compression yes
..
[ other ssh options you want, Protocol, etc. ]
Then run command as:
cat compress_scpdb_jr.sh | ssh tapeserver2tape 'dd of=/dev/nrmt0h'
Better still is to use tar instead of cat, so tape is in std format for later
viewing.
tar compress_scpdb_jr.sh | ssh tapeserver2tape 'dd of=/dev/nrmt0h'
You could also put a small script in the programs path called scp2tape with the
following:
---------
#!/bin/sh
# scp2tape - Grab host and tape, then use tar on other opts to remote dd via
# ssh... NOTE: it only expects a list of files and as last arg remote host and
# remote tape drive. Any -opts will fail, use config file or add code to case.
rem_host=
rem_tape=
files=
# Loop args getting files and remote host and tape
for i in "$*"
do
case "$i" in
# rem_host will be user@host if sent that way. ssh understands
# this as well.
*:*) rem_host=`echo $i | cut -d: -f1`
rem_tape=`echo $i | cut -d: -f2`
;;
*) files="$files $i"
;;
esac
done
tar -cf - $files | ssh $rem_host "dd of=$rem_tape"
--------
You can then have the scripts run:
scp2tape compress_scpdb_jr.sh operator@tapeserver-tape:/dev/nrmt0h
You can modify and add command line options you want to catch to the case above.
I did it this way to keep it simple (just thrown together), relying on the
config file and the special machine name for options processing.
Hope this helps.
