SFTP no authentication if any private SSH key is imported

Wed May 31, 2023 6:57 pm

Hello everyone,

I believe there is a bug in the fetch SFTP mode for ROS 7.9.1

I found out that SFTP fetch download or Upload does not work when there is a SSH Public key is present. The issue persists even if the SFTP username is different from the imported SSH key and password is provided.

Findings:
  1. According to MikroTik it states that auth failed.
    failure: authentication failure (6)
  2. According to SFTP server MikroTik requested a connection but did not provide and auth method.
    2023-05-31T15:36:09.093 DBG sender=connection_failed client_ip=xxx.xxx.xxx.xxx username= login_type=no_auth_tried protocol=SSH error=ssh: overflow reading version string
Did anyone else having the same issues?

Hello,
Same issue I am facing MikroTik indicates that authentication failure occurs, while the SFTP server reports that MikroTik requested a connection but did bot provide authentication method. The error message suggests an overflow reading the version string in the SSH protocol. Please help me to fic this issue. Thanks!
