Information about the UUNet Passive UDP

Overview

There are many on the internet who feel that UUNet is a lost cause. There was an active
UDP against UUNet in August of 1997 which got UUNet's attention. As a result, UUNet finally implemented regulations against spamming by their own dial-up users.

Unfortunately, UUNet steadfastly refuses to do anything about spam from major customers. Email spam continues unabated and netnews spam has begun to rise again. It has become abundantly clear that unless there is some sort of major change at UUNet, the problem will never become resolved.

In July, 1998, UUNet abuse admin Harris Schwartz resigned, announcing his decision to do so the internet at large. This is believed by many to be caused by UUNet's refusal to deal with their spam problem.

There is an ongoing discussion about implementing a passive UDP against UUNet in the newsgroup news.admin.net-abuse.policy. Look for these threads:

The solution that has been proposed is a complete shunning of UUNet. If all sites on the internet refuse to accept any netnews or email from UUNet, an enormous amount of spam will simply disappear.

To this end, all sites currently connected to UUNet are requested to stop exchanging netnews or email with UUNet, and find other sources. Ideally, the sites currently peering with UUNet could simply start peering with each other instead.

Please discuss this with your news administrators, and bring up the subject in your site's local newsgroups.

How to alias UUNet netnews

If your site wishes to alias UUNet at the newsfeed level, here are the instructions for doing this with INN:

On the 'ME' line of newsfeeds, do something like:

ME/uunet.net\
  :*,!control,!junk\
  ::
That one will drop articles from UUNet.

If you just want to not feed them to your peer, you'd do the same sort of thing on their line in newsfeeds:

news.somepeer.net/uunet.net\
  (rest of feed stuff)
ctlinnd reload newsfeeds 'aliasing out uunet'
and that'll do it.

The above is for INN and should be true for the old Netscape news server (which is INN in disguise). It's no doubt different for other software.

How to alias UUNet email

If you have sendmail 8.9.1 or better, run the access_db feature and add the following to /etc/mail/access: # UU.Net is having a problem # These ban their dialups only, not their legit smtp servers # We won't lose any legitimate mail due to these blocks 153.36 571 Banned. See http://colorhouse.com/uunet/ for help. 153.34 571 Banned. See http://colorhouse.com/uunet/ for help. 153.35 571 Banned. See http://colorhouse.com/uunet/ for help. 208.254 571 Banned. See http://colorhouse.com/uunet/ for help. 153.37 571 Banned. See http://colorhouse.com/uunet/ for help. 210.80 571 Banned. See http://colorhouse.com/uunet/ for help. 208.255 571 Banned. See http://colorhouse.com/uunet/ for help. 195.129 571 Banned. See http://colorhouse.com/uunet/ for help. 207.108 571 Banned. See http://colorhouse.com/uunet/ for help. Note: change the sample URL above to one on your own site explaining your reason for the block.

These IP blocks still permit email from UUNet's relay systems, which presumably carry legitimate mail.

UUNet IP blocks

A list of UUNet IP addresses for Dial-Up sites is maintained at the MAPS Dial-Up-List. You should configure sendmail to refuse email connections from any site on this list.

Other connections (e.g. http) are perfectly legitimate.

This list is probably out of date. You should subscribe to the MAPS Dial-Up-List for up-to-date information.

Sites blocking UUNet

Many sites are already blocking UUNet, but they generally do it silently. Here is a list of sites which have announced so publicly.
