Package: lpr
Version: 1:2008.05.17
Severity: wishlist
Tags: upstream patch
It would be very useful to be able to specify remote host ports in "rm", to
take advantage of tunnels (e.g. via ssh -L) and more generally to connect to
remote lpd daemons listening on ports different from the default 515.
A patch is attached to extend the syntax of the rm field in printcap to accept
expressions like
:rm=hostname%port:
in addition to the usual
:rm=hostname:
I believe that '%' is not allowed in host names, therefore this change
shouldn't break anything, but feel free to change it if I'm wrong.
Best regards,
giuseppe
