Let’s talk about network. Chinese version.

1
ssh -v -N -C -D 8089 -o ServerAliveInterval=60 -o ServerAliveCountMax=2048 rankun.org

One step further.

Before long, your will see a lot of error messages like this:

1

debug1: Connection to port 8089 forwarding to socks port 0 requested.
debug1: channel 24: new [dynamic-tcpip]
debug1: channel 24: free: dynamic-tcpip, nchannels 35
debug1: Connection to port 8089 forwarding to socks port 0 requested.
debug1: channel 24: new [dynamic-tcpip]
debug1: channel 24: free: dynamic-tcpip, nchannels 35

Which means your just lost the connection to remote server, but you can use autossh to monitor and restart it.

1
autossh -M 2000 -v -N -C -D 8089 -o ServerAliveInterval=60 -o ServerAliveCountMax=2048 rkus.rankun.org

3-tier forwarding

Idea: shadowsocks + port forwarding (ssh tunnel)

# Start a ssserver in a server outside of China (here: listen on oversea:993)
ssserver -c /path/to/config.json

# Setup a Chinese Cloud server, connect to that ssserver (rkus.json pointing to oversea:993 and listen on cloud:993)
sslocal -c rkus.json

# Finally, connect to cloud server at local (socks on local:8089, local forwarding to cloud:993)
ssh -v -C -N -L 8089:localhost:993 cloud

# If you want the local ssh port forwarding to be auto restart, try autossh
autossh -M 2000 -v -C -N -L 8089:localhost:993 -o ServerAliveInterval=60 -o ServerAliveCountMax=2048 sax.mindfine.com

The result?

Might surprise you :-)

OK, attached the video ;)

Notes:

  • You will need 2 servers or at least ¥50 in your pocket to rent one.
  • Some Internet are bad enough, in such condition, you will need to use a AUTOSSH_POLL env to force autossh check the connection health more frequent. Let’s do a checking every 5 seconds!
    1
    export AUTOSSH_POLL=5 &&  autossh -M 2000 -v -g -C -N -L 8089:localhost:993 -o ServerAliveInterval=60 -o ServerAliveCountMax=2048 hz.youdar.net
