1. (I'm running firewall software and) When I try to send or fetch the clipboard, I get a message indicating the clipboard on the other system is not reachable. What do I do?

Normally, the reason the clipboard on the other system is not reachable is due to:

• the system not being visible on the network (determine whether you can you "ping" it with a network utility? ... can you "see" it for filesharing? ... do I have a route to the system? ... etc.)
  
  
• the networking port you are trying to access is not visible on the network (this issue often appears identical to the previous issue since it's a particular case of the previous issue)

The first issue is general network setup and is beyond the scope of our products and this FAQ. The second issue will be encountered if you are running firewall software.

In addition to the firewall setup that is part of most modern operating systems, there are numerous third-party software firewalls and firewall-setup programs. Regardless of how your particular firewall software accomplishes it, you'll need to setup the following firewall entry:

• allow TCP communications via port 4889 (or the port you have set via the ClipCommControl "Networking" preferences)

If you are using firewall software that distinguishes between client and server behavior, then you should know that, technically, the system that is "receiving a sent" or "supplying a fetched" clipboard is running the ClipCommControl server software and the system that is doing the clipboard sending or fetching is running the ClipCommControl client software.

Depending upon the naming you use for the "System with which to communicate the clipboard", ClipCommControl may also make naming queries that cause access to the Domain Name resolution services and these will normally require setup for any outgoing firewalls. However, since this is not unique to ClipCommControl, it is assumed that these services would already be set up.

2. How do I setup Mac OS X firewall software to allow ClipCommControl?

On the system(s) that will be controlled:

• Open the "System Preferences" and visit the "Sharing" panel.
  
  
• Press the "New..." button
  
  
• On the drop-down, select "Other" in the pop-up menu beside "Port Name:"
  
  
• For "Port Number, Range, or Series:", enter 4889 (or the port you have set via the ClipCommControl "Networking" preferences)
  
  
• Enter "ClipCommControl" (or whatever you prefer) for the "Description:"
  
  
• Press the "OK" button

3. How do I setup Little Snitch firewall software to allow ClipCommControl?

On the system(s) that will be remote controlling other systems:

• Open the "System Preferences" and visit the "Little Snitch" panel.
  
  
• Press the lock button and supply an Administrator's password
  
  
• Depending upon your version, press the "New..." button or select the "New..." pop-up menu
  
  
• On the drop-down, press the "Choose..." button beside the "Application:" label
  
  
• For "Permission:", select the "Allow" item in the pop-up menu
  
  
• For "Server:", enter the IP address of the system you want to control
  
  
• For "Port:", enter 4889 (or the port you have set via the ClipCommControl "Networking" preferences)
  
  
• For "Protocol:", select the "tcp" (or "any") item in the pop-up menu
  
  
• Press the "Save" button

4. The product overview mentions that not all clipboard types will be supported by ClipCommControl. Which types are supported?

Clearly, we cannot test every application, but in general, applications that use well-known, clipboard types will be supported. Applications that declare their own clipboard types may or may not be supported, depending upon that application's implementation. Mac OS X provides many services that make it much easier to develop well-behaved clipboard operations, so we're finding that most applications' clipboard types are supported.

Here are a few that we have tested, at least superficially:
