Denied Error when connecting to Ubuntu SSH Server



Hello Luther,

This problem is occurring on the Ubuntu/Debian based machines. Notice that this error only occurs  when using SecureCRT; sftp through Sftepdrive works without any problem, and connecting to the machine by using other SSH clients works fine as well.

There were many ways to try, like changing the authentication methods, changing the user names, etc, But everything goes in vain. Here is another method worth trying. Follow the steps below.

  • Open SecureCRT
  • Go to options >> Global options >> SSH2 options
  • Turn off/Uncheck the option: "Enable OpenSSH agent forwarding"

Easy method to follow. Hopefully you will find this useful to fix the issue
