Cannot connect using a general SSH client such as PuTTY

Cannot connect using a general SSH client such as PuTTY

Secure FTP Server 2.0 supports FTP only over SSH, which is also called SFTP. Therefore, a "general" SSH client such as PuTTY does not connect to it. PuTTY is TELNET over SSH. If you use PuTTY to connect to Secure FTP Server, then:

  • If you use RAW protocol, you get trashes.
  • If you try to set the protocol to SSH, an error message Server refused to start a shell/command is displayed.
  • If you try to use the TELNET protocol, then Network error: Connection Refused message is displayed.

For example, if you use Red Hat 9 to connect to GlobalSCAPE Secure FTP Server using SSH, it fails as follows:

From the command prompt:

ssh -v -l tuser

This fails during authentication

But, if you use SFTP it succeeds.

From the command prompt:


You are prompted to accept the servers fingerprint and then prompted for your password

Additional Information

PSFTP, a freeware command line SFTP client works using the PuTTY tools.
