[Freerdp-devel] rdpdr plugin usage

Hello.
I have met some issue, but not sure is it bug or feature. :)
I need to redirect sound, disk, COM and LPT ports to server.
If I use command:
xfreerdp --plugin rdpsnd --plugin rdpdr --data disk:flash:/media
serial:COM1:/dev/ttyS0 serial:COM2:/dev/ttyS1 serial:COM3:/dev/ttyS2
serial:COM4:/dev/ttyS3 parallel:LPT1:/dev/lp0 -- <server>
all goes ok, all devices are redirected.

but if I use command:
xfreerdp --plugin rdpsnd --plugin rdpdr --data disk:flash:/media --
--plugin rdpdr --data serial:COM1:/dev/ttyS0 serial:COM2:/dev/ttyS1
serial:COM3:/dev/ttyS2 serial:COM4:/dev/ttyS3 parallel:LPT1:/dev/lp0
-- <server>
disk is not redirected, but com/lpt ports are.

Is the second command not valid? Or is it a parsing bug?

Thank you.

Simply say: first format is right and second one is wrong. :)

No plugin should be loaded for more than once.

Ok, I understood the concept.
But format of redirection options is rather complex and not good for
automatic command line generation. Old rdesktop format was much more
easier, you can append separate option for each redirected device, not
depending for others.

rdesktop is limited to one connection while freerdp is not.

Sorry, what do you mean?
I was speaking only about syntax, not about any kind of functionality.

New question about rdpdr plugin, now about printer subplugin.
For example, I have 5 printers configured in CUPS, and I need to
redirect 2 of them.
I am trying to use command:

xfreerdp --plugin rdpdr --data printer:printername1
printer:printername2 -- <server>

In the output of xfreerdp I see:
"1 device(s) registered
registered device: PRN1 (type=4 id=1)"

Of course, I see only one redirected printer in my session.

So, the question is:
How to redirect two or more local printers to RDP session?

Thank you very much!
I applied the changing to release 0.8.2 and it works. The patch is
very complicated. :)

Hi.
Your commandline looks correct. However I can confirm your problem using
the git sources: Only one printer-definition is currently allowed, the
rest is silently ignored
I am unsure as to WHY this was made so (it does not look as if this was
made with intent: There is a "break" in
channels/rdpdr/printer/printer_main.c#DeviceServiceEntry) but maybe
Marc-Andre or Vic know.
http://gitorious.org/~nilsa/freerdp/nilsas-freerdp-mainline/commits/MultiplePrinters
and it seems to work fine, letting me specify more than one printer
explicitly.
Yours,
Nils

Marc-Andre/Vic:
What do you think of the "patch" ?

This is definitely my mistake. :)

I pushed a slightly different patch, in which the "break" statement only
breaks when using auto printer detection (which was my original
intention). Thanks for pointing this out.
