I was following an TCL SFTP example provided by this ChilKat example. The firewall of my servers are disabled and it seems that script fails at CkSFtp_Connect level and never proceeds to the authentication. I attached the chilkat log output below. The log file doesn't seem to indicate any error. Any help is appreciated! thank you.

The Connect call worked, so it must be that the TCL example code is incorrect? This is the snippet for the Connect call and checking the return value:
set hostname "www.my-ssh-server.com" set port 22 set success [CkSFtp_Connect $sftp $hostname $port] if {[expr $success != 1]} then { puts [CkSFtp_lastErrorText $sftp] delete_CkSFtp $sftp exit }
What is the value of $success that was returned? Maybe the expression in the "if" statement is not correct?
