Configueration

Config file

Default path is $HOME/.config/mallory.json, can be set when start program

mallory -config path/to/config.json

Content:

• id_rsa is the path to our private key file, can be generated by ssh-keygen
• local_smart is the local address to serve HTTP proxy with smart detection of destination host
• local_normal is similar to local_smart but send all traffic through remote SSH server without destination host detection
• remote is the remote address of SSH server
• blocked is a list of domains that need use proxy, any other domains will connect to their server directly

{
  "id_rsa": "$HOME/.ssh/id_rsa",
  "local_smart": ":1315",
  "local_normal": ":1316",
  "remote": "ssh://user@vm.me:22",
  "blocked": [
    "angularjs.org",
    "golang.org",
    "google.com",
    "google.co.jp",
    "googleapis.com",
    "googleusercontent.com",
    "google-analytics.com",
    "gstatic.com",
    "twitter.com",
    "youtube.com"
  ]
}

Blocked list in config file will be reloaded automatically when updated, and you can do it manually:

# send signal to reload
kill -USR2 <pid of mallory>

# or use reload command by sending http request
mallory -reload

System config

• Set both HTTP and HTTPS proxy to localhost with port 1315 to use with block list
• Set env var http_proxy and https_proxy to localhost:1316 for terminal usage

Get the right suffix name for a domain

mallory -suffix www.google.com

A simple command to forward all traffic for the given port

# install it: go get github.com/justmao945/mallory/cmd/forward

# all traffic through port 20022 will be forwarded to destination.com:22
forward -network tcp -listen :20022 -forward destination.com:22

# you can ssh to destination:22 through localhost:20022
ssh root@localhost -p 20022

TODO

• return http error when unable to dial
• add host to list automatically when unable to dial
• support multiple remote servers
