SSH config examples

The SSH config file (~/.ssh/config) allows you to define per-host connection settings such as identity files, jump proxies, and agent forwarding. Below are several common patterns including AWS CodeCommit access, bastion/jump host setups, and GitLab SSH key configuration.

vim ~/.ssh/config
...

Host git-codecommit.*.amazonaws.com

Host  1.2.3.4
  HostName  1.2.3.4
  ForwardAgent yes
  User ec2-user
  AddKeysToAgent yes
  IdentityFile ~/Downloads/cert-developer.pem


# Example with JUMP server
Host e2-bastion  11.22.33.44
  HostName 11.22.33.44
  ForwardAgent yes
  User ec2-user
  AddKeysToAgent yes
  IdentitiesOnly yes
  IdentityFile ~/.ssh/bastion.id_rsa

Host final-server 44.55.66.77
  HostName 44.55.66.77
  ForwardAgent yes
  User ec2-user
  Port 22
  AddKeysToAgent yes
  IdentitiesOnly yes
  IdentityFile ~/.ssh/bastion.id_rsa
  ProxyCommand ssh -q -W %h:%p e2-bastion


# linuxinuse account
