Why would I get an "Error while opening SSH session" error when checking out source code from Stash in my Bamboo plan?

mickey13

I am running Bamboo (5.7.0) and Stash (3.4.1) on the same machine.  I have set up applications links and have enabled "Trusted Applications", "OAuth", and "Basic Access" in both Outgoing Authentication and Incoming Authentication.  I have a linked a Stash repository in Bamboo.  In my Bamboo plan, my first task is "Source Code Checkout" and I reference the linked repository.  Here's part of the stack trace.  Any ideas?

 

com.atlassian.bamboo.repository.RepositoryException: java.lang.RuntimeException: com.atlassian.bamboo.plugins.stash.repository.StashRepositoryException: com.atlassian.bamboo.repository.RepositoryException: com.atlassian.bamboo.plugins.git.GitCommandException: command /usr/bin/git ls-remote ssh://bd2155f1-ceb1-ffab-87ce-870dffffb824@127.0.0.1:59645/house/myapp.git failed with code 128. Working directory was [.]., stderr:

Hello Mickey,

Thank you for your question.

Based on the information you have provided regarding Application Links, you have set them up using different authentication methods so every time a request is made the same not necessarily gets interpreted in the same way on the other end.

When using Bamboo 5.6+ and Stash 3.2+ we would suggest on creating application link with default settings, so could you remove the existent one and recreate it as per following:

• The servers have the same set of users and usernames disabled
• I am an administrator on both instances enabled

will result in application link created with:

• Trusted Apps authentication disabled
• OAuth authentication enabled:
  * Allow 2-Legged OAuth enabled
  * Allow user impersonation through 2-Legged OAuth disabled
• Basic Auth authentication disabled

Important to notice the following should be same used to access the application from your web browser.

• Hitting Bamboo from your web browser: http://bamboo.base.url

• Bamboo administration >> System >> General configuration >> Base URL (http://bamboo.base.url)

• Hitting Stash from your web browser: http://stash.base.url

• Stash administration >> Settings >> Server Settings >> Base URL (http://stash.base.url)

• Stash administration >> Settings >> Server Settings >> SSH access
• * [x] SSH enabled 
• * [x] SSH access keys enabled 
• * SSH Port: 7999

In case you continue on experiencing issues, I would suggest you on raising a Support ticket and adding this Question to the tickets description along with a Bamboo Support Zip.

If you find this answer useful, I would kindly ask you to accept it so the same will be visible to others who might be facing the same issue you have inquired.

Thank you for your understanding.
