Чтобы решить эту проблему, мы попробовали следующие обходные пути, однако пока ни один из них не помог нам решить ее.

1.  ~/.ssh/id_rsa.pub key and user name verified in Gerrit GUI Settings.
2.  Permission applied like 
chmod 700 ~/.ssh
chmod 600 ~/.ssh/*
3.  Checked /etc/hosts.allow & /etc/hosts.deny files with working machine, both are identical.
4.  Executed unset https_proxy & unset http_proxy commands
5.  Checked .gitconfig file. 
6.  Created vi .ssh/config file and added below info.
Host gerrit.server.com
User git-user
Port 29418
7.  Reinstalled OpenSSL and rebooted the machine.
8.  Tried dpkg-reconfigure openssh-server
9.  Firewall not running.
10. Ifconfig shows only eth0 & lo (No problem here).
11. Verified /etc/ssh/sshd_config with working machine, no problem with this file.
