[aswamca]

Questions:
My requirement is to deploy the artifacts (created in teamcity while compiling the code) via teamcity to dev server through ssh deployer using SFTP , my build agent is runing on windows machine and i am trying to deploy artifact on linux machine

how to get ride of the auth fail?
Please specify with some examples how each deployers are working?
I am using my credential for deployment

below is the error:

1. Select "verbose" messages level on build log tab to see exact SSH messages exchange. This will tell, why auth fails.
2. Check, that password auth type is allowed by ssh server, keyboard-interactive is not enough.

[aswamca]

Hi ,

password auth type is already allowed by ssh server.

I have enabled the "verbose" and still deployment is failing now we are getting below error

Please help , need urgently.. Thanks in advance

@aswamca

• go to build results,
• open build "Build Log" tab
• select "Verbose" in "View" combobox
• find the SSH debug messages in build log (should have appeared)
• post them here.

If no SSH debug messages are present in build log after choosing "Verbose", please update the plugin or consult the logs of SSH server

[aswamca]

Hi According you SSH server is target location ,where through winscp I am able to upload files on target location . So what message you are trying to look here ..
We have sent verbose log only to you, Please let us know why this authentication stopping ??
Thanks

[Nikita Skvortsov]

The verbose log that you sent does not contain SSH debug messages
It means, you are using old version of plugin or TeamCity server.

Please install a latest version of the plugin available here using this instruction

Then try again and look for debug messages.

I am getting the same error using teamcity 2018.2.2. I followed @nskvortsov instructions but it didn't help.
