RunCommand() hangs in FreeBSD

[dca00]

With the help of password prompt event suggested by @darkoperator, I was able to connect to FreeBSD and run a bunch of commands. However, once I make a 2nd connection to the same host and call 1 RunCommand(), the 2nd RunCommand() hangs.

I cannot reproduce this behavior in any Linux distro or version (RHEL, openSUSE, SLES, Debian, Fedora), so it is probably FreeBSD-specific.

So, scratch false-positives of the 2nd connection and 2nd command. I narrowed this down to the actual command: grep -v ^# {0}.
This perfectly legitimate command executes fine on the physical FreeBSD console with the standard csh shell or through PuTTY but hangs through RunCommand(). It also executes fine on any Linux host.

Test with Plink, since plink uses the same API on the server side as ssh command(executes directly the binary and returns the stdout with no concept of a session), if the results are the same I would say it could be because it requires a full shell like, in that case you will need to use a ShellStream, that would be the same way Putty works since it creates a Console Shel sessionl for you to enter the commands. That is why when SSHCommand() is used and one does cd to a folder and then pwd you see it does not changes because it does not interact with an actual console session but uses the same sshexec api as Plink, a ShellStream should work like Putty on that regard where you would write and read from the stream created.

Turns out that I won't be allowed to do as much R&D as this library requires :(
They already have a legacy wrapper for OpenSSH and will have to live with it.
