LSH IS A WORK IN PROGRESS. IT WILL NOT PROVIDE ANY SECURITY ON SYSTEMS THAT LACK /dev/random. THERE MAY BE OTHER SERIOUS BUGS THAT MAKE IT TOTALLY INSECURE.

Why:

I like the Macintosh, and I needed to access Linux boxes through Internet securely.
The only SSH2 client for MacOS I could find is a commercial product that costs
more than $100, and it crashes my Mac when closing a session...
Since it's best to do things by oneself, here's MacSSH.
