It would be nice to be able to chain connections. Starting from one system, connection to another system, and then starting a connection from that system to a third system, etc...
Of course on each of the the systems in the chain there would be a "helper app" running to propagate the connection information necessary to connect to the next target system.
I initially thought that the sub connections are implementation of this behavior.
This would be very useful for service providers. The typical scenario in these environments is to connect to a system at the client premise from where an additional connection needs to be established to a target system.
Although they are not managed automatically at this time, you could implement a solution. I'll admit many would describe it as "poor" to "fair", but for a limited number of connections its workable.
RDM support launching sessions from the command line. If you go in the advanced settings for a session, you will see at the bottom a textbox containing a command line to launch this perticular session and a button that will create a shortcut on the desktop.
So the solution is : on your remote host, create desktop shortcuts for the second level sessions you want to easily launch.
That feature is often asked and we have a few ideas to implement it, but they require a significant time investment.
This could be a workaround we could work with. We have globally unlimited license of RDM(S), so we could install a local RDM on the "jump-in" systems under our control.
This could maybe be a suggestion how to implement it. Have a stripped down version of RDM running on all the machines in the chain and use it to propagate session infomation (hostname, username, password, connection type...) down the chain.
We have something that will help you, have a look at this:
