Multiplicity Pro - copy/paste between computers broken? IE9 RC issue?

from Stardock Forums

Hi,

 

Having issues with Multiplicity Pro on two Win 7 x64 computers connected on the local giga-bit Ethernet LAN. Everything seemed to be working well until recently when I found copy/paste between computers seemed to be broken. Multiplicity works fine with moving the cursor/keyboard between computers. However whenever I copy (clipboard or file) on the primary and then move to the secondary I get a quick message on the secondary it is copying a file, but then Multiplicity disconnects on the primary, and immediately reconnects. Nothing remains in the clipboard to paste in the secondary. Both computers running v 1.24.

 
I've uninstalled and reinstalled on both computers with full reboots between. Firewall rules seem OK and probably working fine since the cursor/keyboard part is working fine. Any thoughts on how to fix this?

Hi All,

Just in case someone else gets this same problem. I found the following solution (unfortunately without any real support from Stardock):

The copy/paste problem with Multiplicity Pro kept bugging me so I did a little debugging and ran Sysinternals Procmon on Multipl.exe on both secondary and primary computers. In the copy/paste operation from primary to secondary I found Multipl.exe had a filename collision error on the secondary computer with "C:\Program Data\Multiplicity Temp". I deleted the zero size file and lo and behold, everything now works as it should.
Surprised this issue hasn't come up before. Looks like the file "Multiplicity Temp" is supposed to be deleted by Multiplicity after each copy/paste, but for some reason it wasn't on the secondary and thus the problem. 

Hope this helps future troubleshooting sessions.

Regards,

CharlesH

I opened a support ticket with Stardock about this very issue today, but while I was waiting for a reply, I found a solution. You need to have ports 30564 and 30565 open in your firewall on all involved computers. Port 30564 alone will get you mouse and keyboard control, but port 30565 is also required for file and clipboard transfers. Not sure about audio transfers, as I have not had occasion to test that yet.

I'm having the same issue here with my setup.  Copy & Paste isn't working but everything else is.  I've tried deleting the files in C:\Program Data\Multiplicity Temp and that doesn't help.  I've opened the ports, 30564 and 30565 and that doesn't work.  Even disabling Windows Firewall on both PC's doesn't work.

 

It's copying from the slave to the master but not the other way round.  It's really annoying becuase I'm so used to it and I can't live without it :)

I have placed a ticket for you.  You should have mail on the matter.

Yes, they have emailed but they haven't given any sort of answers, just questions about my setup.  No reply in over 48hrs.

I have the exact same problem here.  Did support ever help you?  I can copy/paste from secondary to primary but not primary to secondary.  Running Windows 8.1 on both systems and everything was working until recently.


Tried the whole firewall off, re-installed,  deleted any mention of multiplicity on both ends - always come back to same result.


unhappy,

Erik

If everything was working previously then it points to something changing on your setup.

For copying from the primary to secondary the primary must have port 30565 open on it.  For secondary->primary it would be the same port but on the secondary.

Typically not being able to copy one way would point to a firewall blocking it on one of the ends which will be the end you are copying from.

This is a known issue with the current version of Multiplicity (2.02).

If a secondary is more than one machine away from the primary (Primary ---> right 1 secondary ----> right 2 secondary), then the copy and paste fails if you past directly from Primary to right 2 secondary. If you paste 'along the way' to each, it does work. You could also enable this feature to wrap around the other way and it would work:

A fix in being worked on.

This thread relates to MP 1.x and the clipboard code was changed completely in later versions.

If you ever find clipboard only works one way, it means the firewall on the computer which has the clipboard contents is blocking Multiplicity.  This can happen with third party firewalls which do not use the OS firewall rules which Multiplicity will have setup.

Also if one computer believes it is on a public network vs a home/work network it will have the firewall blocking Multiplicity as Multiplicity rules are only set to be open when on a trusted network (for added security).  Occasionally a computer can set itself to public in error.
