ssh to Listen 443 on Snow Leopard

Surf everywhere as if you were at home

In order to bypass evil company firewall and to surf safely on unsafe wifi. I keep an ssh server listening on the port 443.

Then from my laptop or my local computer I just have to launch the marvelous

ssh -f -p 443 -ND 9050 username@host

and a local socks proxy listening on port 9050 is launched. The socks proxy will transfer local requests via the ssh tunnel. Therefore I can surf locally as if I was on my own computer. I can put password and card number without fear the local wifi network to be sniffed. I simply need to configure my web browser to user the socks proxy on localhost and port 9050.

I get this information from this post.

Ssh and Snow Leopard(c)

Here I don’t want to talk about how great socks proxy via ssh tunneling is but how to configure my local server.

I have Mac with Snow Leopard(c) at home and it is far from enough to modify the /etc/sshd.config file. The system use launchd to launch starting daemons.

I posted the question on Apple Discussions in this discussion thread. Thanks to all guys who helped me. And the solution is:

Create the file /Library/LaunchDaemons/ssh-443.plist containing:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "">
<plist version="1.0">

It is a copy of /System/Library/LaunchDaemons/ssh.plist with some modifications:

  • the SockServiceName from ssh to https.
  • the Label from com.openssh.sshd to something not existing as local.sshd

Tell me if it was helpfull or if you have any question.
