Wikipedia has a nice listing here; I'd recommend looking at the " Technical" section for one which is for windows which has SCP support (file transfers over SSH)

Okay thats nice. I was searching for ssh not ssh clients. Much more info there.

Well, SSH is a server; and theres a 99% chance your provider will be using OpenSSH as a server (as it is what everyone uses lol); the CLIENTS are what you'll be using to communicate

Something new for me that I am not sure how to address.
Case sensitive issues with users bookmarks.

On a windows server this was not a issue.
Looking at the server logs I get a lot of missing file errors some are due to malware bots( non legit urls). But some are due to users that used upper and lower case in their bookmarks. They are legitimate urls just the wrong case.

One of many examples is Ubbthreads instead of ubbthreads.
Or Index.html not index.html

For now I just added another file Ubbthreads.
Also some still use classic paths like Ultimatebb instead of ultimatebb. Did the same thing with them added duplicate redirectors.
This is just one of many many case examples depending on what the user has.

Is there some type of rewrite rule that would correct this problem? If not what is the best resolution?
