Tunnelling via Skyputty

Services on the internet run on ports - like channels on TV. Many popular services run on standard ports e.g. A standard port for web traffic is 80 or 110 for POP3 e-mail. Many service providers, including Skynet, restrict access to ports (and therefore service) based on where you're connecting from.

In order to access some skynet services (such as proxy or news), you will need to "tunnel" ports. This creates a port on your machine and connects that, through skynet, to the remote service. The example below connects port 3128 on your local machine to the Squid proxy service on Skynet. If you set your browser (Internet Explorer or Firefox) to use a proxy on localhost port 3128, it will seem to any website you open as if the connection is being made from within Skynet.

Grab skyputty, or putty off [WWW] http://www.skynet.ie

  1. Go to the tunnels tab.

  2. For the source port put 3128 (The port here doesn't have to be this number. Just remember what number you set it as)

  3. For the destination put proxy.skynet.ie:3128.

  4. Hit add and login as normal.

  5. For any applications tell them to use a proxy on localhost at port 3128.

Here is a list of common ports you might want to tunnel and the skynet machines that run them

Service

Skynet machine

Proxy

3128

proxy.skynet.ie

SSH

skynet.ie

SMTP (outgoing e-mail)

25

mail.skynet.ie

E-mail (POP3)

110

mail.skynet.ie

E-mail (POP3S)

995

mail.skynet.ie

E-mail (IMAP)

143

mail.skynet.ie

E-mail (IMAPS)

993

mail.skynet.ie

News

119

news.skynet.ie

IRC

6667

irc.skynet.ie

Note: Connections to the mail server are not blocked by Skynet from anywhere. We would recommend an IMAPS connections. If you want to send e-mail through the Skynet mail server (SMTP), you will need to enable TLS for your outgoing mailserver and login with your Skynet username and password. You can connect to the IRC directly from the outside by enabling SSL, connecting to irc.skynet.ie port 9999 and logging in with your Skynet username and password.

Setting up a SOCKS relay

Grab skyputty, or putty off [WWW] http://www.skynet.ie

  1. Go to the tunnels tab.

  2. For the source port put 1080.

  3. For the destination put skynet.ie:1080.

  4. For the radial buttons select dynamic and IPv4.

  5. Then hit add and login as normal.

  6. For any applications tell them to use a socks localhost at port 1080.

Note: I believe this will only tunnel TCP traffic, which is fine for most normal applications (i.e. web) and you have to keep the putty window open for it to work.
