I have configured the replication with following configurations
$cat /var/gerrit/review_site/etc/replication.config
[gerrit]
autoReload=true
[remote "bt-git"]
projects = ^vt-(.*)$
push = refs/heads/*:refs/heads/*
url = git@git.something.com:/${name}.git
My ssh config file looks like this one,
Host git
HostName git.something.com
User git
IdentityFile /var/gerrit/.ssh/id_rsa
StrictHostKeyChecking no
UserKnownHostsFile /dev/null
Although I have already added the right set of hostkeys in my ~/.ssh/known_hosts the replication plugin fails with the following stacktrace
[2017-08-02 13:08:55,194] [a6b3228d] Replication to git@git.something.com:/vt-test.git started...

However I am able to clone the repository from the same machine and it works seamlessly.
