I don't think tar is capable of transferring a directory listing without

If 'tar' is permitted by the remote 'sshd' config then I don't
see the danger of also allowing '/bin/ls', especially since
only the backuppc user on the local system would be allowed
to initiate a remote '/bin/ls'. If the right command isn't
'/bin/ls' then there could be a BPC client-specific configuration
option with the correct command.
Maybe one way to get a directory listing with tar.....
run 2 tar commands.
First....
tar -cvf /dev/null
then you can pipe the output anywhere you like.
Then run the real tar.
I do this with tape backups to get a before listing to compare with what
it writes.
/bin/tar -cvf /dev/null --totals --exclude-from "$EXCLUSIONLIST"
--ignore-failed-read . 1> ${LOGDIR}/${FULLLIST} 2> ${LOGDIR}/${TOBEDONE}
/bin/tar -cvf /dev/st0 --totals --exclude-from "$EXCLUSIONLIST"
--ignore-failed-read . 1> ${LOGDIR}/${WRITELIST} 2>> ${LOGDIR}/${BACKUPLOG}
the tar to /dev/null actually doesn't take that long at all, maybe a few
minutes depending on the size.

Les
