The downside of all this is that until now SecureCRT has only been available on Windows, and months of begging the devs to come up with a Linux version haven't helped at all. Attempts to install it on WINE have either failed till now or been very buggy.
Apparently this has all been fixed recently and SecureCRT now works fine with the latest version of WINE available at Sourceforge. You must use that version because using "apt-get wine" or whatever you use to connect to repositories install the buggy versions.
More info is avalable here.
BTW, there is also an open source product called SecureGRT for Linux but this is still in the Pre-Alpha development stage and has only 1 developer.
There are 10 kinds of people, those that understand binary, and those that don't.
