I am setting up jenkins and gerrit on the same host, and one thing I need is to have gerrit and jenkins communicate with each other.
When I add the ip address of the host (say 10.25.26.27) then I am not able to get the gerrit trigger to connect to 10.25.26.27. To debug, I tried:
ssh -p 29418 user@10.25.26.27 -v
Due diligence with ssh-keygen and copying the id_rsa.pub has been done.
The output of the above command is:

However, when I try the same from another ip address, say 10.24.25.29, I can connect successfully.
I need to run both gerrit and jenkins from the same host. Appreciate help on debugging this issue.
