Hello, we were using 2.2.4 wowza without any problem. Today we opened a new instance with Wowza 3.0.5 and we tried to connect with WinSCP. We filled the host name with the associated elastic ip, we filled username with root and selected the ppk file we were using successfully on our old wowza instance. The problem is that when we try to connect we get the following error: * * * Error * * * Received too large (1349281121 B) SFTP packet. Max supported packet size is 1024000 B. The error is typically caused by message printed from startup script (like .profile). The message may start with ““Plea””. * * * Cannot initialize SFTP protocol. Is the host running a SFTP server? * * * OK Reconnect (2 s) Help * * * Do you know why we can’t connect? Thank you! ---

This is caused by the root logins being disabled on the v3 images (it’s a security feature inherited from the underlying Amazon Linux image). You’ll need to use either the ec2-user account or the wowza account (default password is the instance ID). -Ian
