Hello,
I'm executing Tests on a remote machine via WebServices. The result files of the tests are located on the remote machine. I want to copy them from the remote machine via a powershell or commandshell buildstep into the working directory of my build agent. I'm using key based authentification. When I issue the command from the working dir on the build agent it works. If I'm using the command from the buildstep it doesn't.
Im using:
scp -C -r -v -p -i ./id_rsa administrator@192.19.253.28:/D:/Result.xml ./testResultLocal.xml
The interesting part in the log shows:
12:31:04][Step 7/9] debug1: identity file ./id_rsa type -1
It seems that scp is not accepting the private key, any ideas why this happens during the buildstep? Any help is appreciated, I'm kind of lost at the moment. We are using Teamcity 10 Enterprise ...
Thanks for your help.
Mark

Hi Mark,
Sorry for the delay. What kind of build step are you using? Command line? Some sort of scripting? Or SSH Upload? Any reason not to use the SSH Agent feature (https://confluence.jetbrains.com/display/TCD18/SSH+Agent)?
Judging from the end of the debug log, it seems like it's trying to open a tty to read the passphrase and it obviously can't (as teamcity's spawned processes are non-interactive). This could mean that it's actually reading the key properly (or at least some key) and trying to open it (which requires a passphrase), unless I'm misunderstanding something. Could you check that?
