[筆記] ssh config tunnel

可直接把常需要使用跳板機的機器直接寫在~/.ssh/config , 之後可直接使用alias連線

config example

~/.ssh/config

Host auto
  ProxyJump bastion
  User ubuntu
  Hostname 10.0.55.xxx
  IdentityFile /home/hccuse/.ssh/auto.pem  # the key that tunnel machine connect to target machine

Host bastion
  HostName 13.230.199.ooo
  User ubuntu
# IdentityFile:        # the key that mypc connect to tunnel machine 

• auto: remote target machine alias

• bastion: tunnel machine

• 13.230.199.ooo: tunnel machine host

• 10.0.55.xxx: remote target machine host
