SFTP and Google Cloud VM instances

Report · Dec 13, 2017

Google Cloud VM instances, like many virtual hosts, require a SSH key to log into the machine and transfer files. This seems to be too complicated for DreamWeaver to handle. I have tried every combination I can think of under the server config to get this to work and I can't. I'm trying SFTP on port 22, with a username and an identify file.

Using WinSCP or FileZilla, I can use my GoogleCloud.ppk key on port 22 and connect and transfer files just fine. Same with logging in with a terminal like Putty.

At the moment to get around this I have set up a virtual box running Linux, and I FTP my files to it, and it then SFTPs the files automatically to my Google Cloud VM instance.

If anyone has any suggestions or a solution I would appreciate it.

Have you had a look at this solution Strange SFTP error message ?

Hi,

Can you help us figure out the ciphers, MACs and KexAlgorithms supported by the hosting server that you are trying to connect to so that we can debug it from our end?

I'm happy to assist in any way I can, but really it would be easier for you to set up a Google Cloud VM and try it yourself. They give you a free server for a year.

Otherwise, I'm happy to look at SSH logs or anything else that would be helpful.

I got into the server and turned on the maximum debugging for SSHD. Here's the results (my IP is masked, but everything else is raw):

Hi,

Thanks a lot for sharing the logs with us. We are investigating into it.

Also, I see, you are trying to connect using .ppk file. As DW does not support .ppk file. Can you please convert .ppk into .pem using putty generator and try for the connection again.

Looking forward to your reply. Or you can drop an email to kudyaratadobedotcom.

Turns out that was the issue, gotta use a .pem. As soon as I converted the file and tried it it worked.
