Thanks for that Larry,
the simple script below has worked in testing so I'll tidy it up and stick it

Gary
#!/usr/bin/perl -w
$file='/var/lock/sshport';
unlink $file||warn "cannot delete '$file': $!\n";
open(FOUT,"|ssh -L 110:stan:110 stan")|| die "cannot open pipe: $!\n";
while ( ! -f $file ) {
sleep 5;
}
close(FOUT);
