Description

Currently, if I want to connect to an internal server through a jump host and use it as part of the system proxy, I need to manually establish a local SOCKS5 proxy using ssh -D and then add it to mihomo proxy groups. The 2FA process can be automated with an Expect script or a modified version of sshpass, as long as the 2FA secret key is available. Of course, official software like Termius or MobaXterm doesn't allow 2FA automation, but I think Mihomo could easily support it. The ideal configuration file might look like this:

proxies:

• name: "ssh-out"
  type: ssh

  server: 127.0.0.1
  port: 22
  username: root
  password: password
  private-key: key
  private-key-passphrase: key_password
  host-key:

  • "ssh-rsa AAAAB3NzaC1yc2EAA..."
    host-key-algorithms:
  • rsa
    2fa-settings:
    2fa-TOTP-shared-secret-key: "4LSI744DKVCDCJMXBCDYA1V3QE"
    2fa-one-times-password-prompt: "verfification code:"
    2fa-password-prompt: "password:"
