Tips

ssh-keygen

# key generate
ssh-keygen -t ed25519 -C {comment}
# change password
ssh-keygen -f {private-key-path} -p

SSH

# basic usage
ssh -i {pub-key-path} -l {user} -p {port} {host-ip}
# multi-stage ssh
ssh -i {pub-key-path} -o ProxyCommand="ssh -W %h:%p -i {pub-key-path} -l {user} -p {port1} {host1-ip}" -l {user} -p {port2} {host2-ip}
# ssh over https
# 1. open port 443 of sshd
# 2. install corkscrew
ssh -i {pub-key-path} -o ProxyCommand="corkscrew {proxy-ip} {proxy-port} [authfile] %h %p" -l {user} -p 443 {host2-ip}
vim [authfile]
{user}:{passwd}
# only ssh local port forwarding
ssh -i {pub-key-path} -N -b {host1-nic-ip or 127.0.0.1} -L {port1}:{host2}:{port2} -l {user} -p {port} {host-ip}
# only ssh remote port forwarding
ssh -i {pub-key-path} -N -b {host1-nic-ip or 127.0.0.1} -R {port1}:{host2}:{port2} -l {user} -p {port} {host-ip}
# SSH dynamic port forwarding
# connect to socks://127.0.0.1:{port}
# can com via ssh server
ssh -i {pub-key-path} -D {port} -l {user} -p {port} {host-ip}
