Some helpful troubleshooting tips for SFTP jails

Further to my previous post on SFTP jails, I've run across a few issues. When logging in via command line after first setting up the jail, you may encounter immediate disconnects with the response "Connection Closed". One possible cause of this is missing files, specifically "/lib64/ld-linux-x86-64.so.2" under the jail. There are other files that can possibly be missing, but that's a biggie if you're running a 64-bit kernel. If you're running WinSCP, you may also encounter the error message "Is the host running a SFTP server?"
