http://NedaNet.org:You can help by adding bandwidth and computing power to our network. It is still forming and growing; the more widely dispersed it gets, the less vulnerable it will be to denial-of-service attacks, blacklisting, or physical action by the Iranian government and its terrorist allies.

If you are a Linux or *BSD or Mac OS/X user, we have a detailed recipe for setting up and registering a Squid proxy for the revolutionaries’ use. Update: We are no longer recommending people set up plaintext squid proxies. The Iranian regime appears to be doing deep-packet inspection on all traffic now.

To help support safe communications that are immune to deep-packet inspection, you can set up a Tor relay; this will help dissidents to communicate in and out of Iran without being traceable by the regime. See these directions.

Squid instructions for Windows users are under development.

Alternatively, there’s a bootable CD called rbox that sets up a NedaNet site in a box. I’m told it’s usable but still being polished. Windows users (especially) may want to go that route to avoid security issues.

We have an IRC channel, #irantech on freenode.net, where we gather to help each other help the Iranians.

Other people are pursuing different approaches. Anonymous Iran supports anonymized chat communication and offers advice on secure communications.

Iranians can now get free untraceable IP addresses from IP Rental.

Security warning
If you are an Iranian, be aware of these facts:

The regime appears to be using deep packet inspection on all traffic in and out of Iran. Do not use unencrypted communications for anything sensitive unless you want to be jailed, tortured, and killed!
A source in Iran tells us all IM (Instant Messenger) traffic in Iran was already being monitored or logged 4 years before this crisis. We think it’s safe to aassume they have not stopped.
Doing the right thing
Core members of NedaNet have already received death threats from persons plausibly believed to be agents of the Iranian regime or allied terrorist organizations such as Hezbollah. We expect more of us to be targets of threats, intimidations, and possibly actual violence before the crisis resolves. Be aware of that risk if you choose to join us.

But today in Iran, thousands of people are putting their lives on the line every day in direct confrontation with the Iranian regime’s thugs, facing danger that reduces any risks we run to a triviality. They’re not running away. We won’t either.

Public contact and operational security
I’m Eric S. Raymond. Some of you will know me from the open-source movement as “ESR”. Because of the real threat of terrorist action against us, most of NedaNet is keeping a low profile. I have volunteered to be a visible public contact because (a) I’ve done this sort of public-face work before, (b) I already got my jihadi death threat from Iran in 2006 before NedaNet, and (c) I’m not easily intimidated.

Think of me as a cut-out. I have very carefully not asked who our contacts in Iran are. I don’t even know who most of the rest of the NedaNet people are, and don’t intend to try to find out; they’re basically just handles on an IRC channel from whom I get URLs and files. And for any agent or proxy of the regime interested in asking me questions face to face, I’ve got some bullets slathered in pork fat to make you feel extra special welcome.

Due to agitation by blowhards with too much time on their hands, I add the following disclaimer: I do not necessarily speak for the entirety of NedaNet. (Now maybe they’ll stop yattering on the channel so we can get more work done.)
