Bridge
Bridge is a TCP proxy tool Support http(s)-connect socks4/4a/5/5h ssh proxycommand
Supported protocols
Example
Mapping example.org:80 TCP port to 8080 port of the local machines.
bridge -b :8080 -p example.org:80
# `curl -H 'Host: example.org' 127.0.0.1:8080` will return to the target page
Proxy that can go through various protocols.
bridge -b :8080 -p example.org:80 -p ssh://username:password@my_server:22
bridge -b :8080 -p example.org:80 -p ssh://username@my_server:22?identity_file=~/.ssh/id_rsa
bridge -b :8080 -p example.org:80 -p socks5://username:password@my_server:1080
bridge -b :8080 -p example.org:80 -p http://username:password@my_server:8080
bridge -b :8080 -p example.org:80 -p 'cmd:nc %h %p'
bridge -b :8080 -p example.org:80 -p 'cmd:ssh sshserver nc %h %p'
It can also go through multi-level proxy.
bridge -b :8080 -p example.org:80 -p http://username:password@my_server2:8080 -p http://username:password@my_server1:8080
Using proxy protocol(http/socks4/socks5) instead of direct TCP forwarding.
bridge -b :8080 -p -
bridge -b :8080 -p - -p http://username:password@my_server1:8080
# `http_proxy=http://127.0.0.1:8080 curl example.org` Will be the proxy
You can also use ssh to listen for port mapping from local port to server port,
due to the limitation of sshd, only 127.0.0.1 ports can be monitored.
if you want to provide external services,
you need to change the 'GatewayPorts no' in /etc/ssh/sshd_config to yes
and then reload sshd.
bridge -b :8080 -b ssh://username:password@my_server:22 -p 127.0.0.1:80
More of the time I'm acting as a ssh proxy.
# in ~/.ssh/config
ProxyCommand bridge -p %h:%p -p "ssh://username@my_server?identity_file=~/.ssh/id_rsa"
Usage
Usage: bridge [-d] \
[-b=[[tcp://]bind_address]:bind_port \
[-b=ssh://bridge_bind_address:bridge_bind_port [-b=(socks4://|socks4a://|socks5://|socks5h://|https://|http://|ssh://|cmd:)bridge_bind_address:bridge_bind_port ...]]] \ //
-p=([tcp://]proxy_address:proxy_port|-) \
[-p=(socks4://|socks4a://|socks5://|socks5h://|https://|http://|ssh://|cmd:)bridge_proxy_address:bridge_proxy_port ...]
-b, --bind strings The first is the listening address, and then the proxy through which the listening address passes.
If it is not filled in, it is redirected to the pipeline.
only SSH and local support listening, so the last proxy must be ssh.
-d, --debug Output the communication data.
-p, --proxy strings The first is the dial-up address, followed by the proxy through which the dial-up address passes.
