I can neither confirm nor deny that IBM's ssh-proxyc is based on BSD netcat.

Yeah, I need a ssh-proxyh, I think!

Based on the name, that seems to support SOCKS(5) proxy servers.

The (BSD) netcat (nc) `-X` means to use the HTTP(S) CONNECT protocol proxy.

I don't have convenient access to that document.  Though I should find a
copy as I hope it's as interesting as it could be.

Based on the name, that seems to support SOCKS(5) proxy servers.

The (BSD) netcat (nc) `-X` means to use the HTTP(S) CONNECT protocol proxy.


See the IBM z/OS OpenSSH User's Guide for more information.

IBM ships a command with z/OS:  "ssh-proxyc  - HTTP SOCKS-5 Proxy command for 
ssh client"
See the IBM z/OS OpenSSH User's Guide for more information.
