I got hands on this tool … almost too late. In short words: marvellous, ingenious, gigantic.
You work with servers from a Windows Desktop? Do not go without this!
SSH, X11, Browser, Session management, Key handling all inside plus tons of others like RDP (yuck!).
The flexibility of this tools is breath-taking. For smaller environments you may be fine with the free version, but it can only store a certain number of server-records.
Licensing MobaXterm will remove this limit. It is really not a fortune, they ask.
What I really like about this tool is that X11 and SSH are integrated into one solution, even serial connections are possible. It is a really nice console to switch back and forth between many concurrent connections.
