ANNOUNCE: SURBL TTLs optimized at 15 minutes
by Jeff Chan 17 Sep '04

17 Sep '04

After trying DNS TTLs at 1 hour, 25, 20, 15 and 10 minutes, it appears that 15 minute TTLs optimizes both name server traffic and the quickness of records being added or deleted from the lists. Therefore, we are standardizing on 15 minute TTLs for all SURBLs. Note that this result applies to SURBL data and uses of it. It may or may not apply to other types of RBLs.

ANOUNCE: Welcoming new public name server, misc name server news
by Jeff Chan 17 Sep '04

17 Sep '04

We'd like to welcome and thank the addition of a new public SURBL name server administered by: Chris Stone of AxisInternet, Inc. Without all of our public nameservers and the help of their administrators, SURBLs would not be possible. Our thanks to all of them! Some additional name server news: all of the name servers which we had temporarily commented out while they were being repaired have been fully returned to service. A name server status page can be found at: http://www.surbl.org/nameservers-output.html Also in case we haven't already mentioned it, the name servers are now organized into letter names like a.surbl.org, b.surbl.org, ... through n.surbl.org, and each name round robins into two or three servers. As more are added, we will try to balance them all at three servers per name, so that traffic is balanced overall. Having more than one server per name lets us comment one out without needing to change NS records in the subdomain zone files and delegations, when maintenance on a particular name server needs to be done, etc. It also keeps the SURBL DNS packets smaller to have fewer name servers listed in the NS records.

ANNOUNCE: Top SURBL DNS blocklist hits joins top whitelist hists
by Jeff Chan 17 Sep '04

17 Sep '04

To follow up on an earlier announcement, in addition to a list of the top SURBL DNS queries that hit whitelists: http://www.surbl.org/dns-queries.whitelist.counts.txt we've added a list of the top blocklist hits: http://www.surbl.org/dns-queries.blocklist.counts.txt Though the sample size is somewhat small at 32k queries over the trailing 48 hours, the data may perhaps be useful for expiring records from blocklists or checking whitelists. We can increase the sample size if anyone thinks it worthwhile. Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

ANNOUNCE: Top SURBL DNS queries and whitelist hits
by Jeff Chan 07 Sep '04

07 Sep '04

We've made a list of the top SURBL DNS queries into my name server: http://www.surbl.org/dns-queries.counts.txt and a version with only whitelist hits: http://www.surbl.org/dns-queries.whitelist.counts.txt The sample size is somewhat small at 32k queries over the last 48 trailing hours, but it's still somewhat interesting. Specifically 2000 queries are sampled every 3 hours. (Please ignore some of the junk at the end of the unwhitelisted counts. That's stuff left over from DNS packets which I haven't cleaned out yet.) I'm slightly surprised how high in the total rankings some spam domains are. That represents a huge amount of spam sent and blocked. :-) Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

Announce: GetURI 1.5 Released -- Major additions
by Jeff Chan 07 Sep '04

07 Sep '04

(forwarded:) From: Ryan Thompson <ryan(a)sasknow.com> Date: Monday, September 6, 2004, 5:50:46 PM Subject: Announce: GetURI 1.5 Released -- Major additions Web site URL: http://ry.ca/geturi/ I'm extremely pleased to announce the release of GetURI 1.5. This is a major new release that includes many new features to aid in the fight on spam. GetURI is a program designed to make identification and hand- classification of URIs easier. This new version supports spam *and* ham message directories, enabling you to include ham messages in your checks, to quickly identify domains which appear in ham. Previously, only spam messages could be fed to GetURI. Those processing spamtraps, or hand-checking submitted domains for blacklisting or whitelisting will be pleased to know that GetURI now supports two new options: --hamdomains, and --spamdomains, which accept filenames containing simple lists of domains that appear in ham and spam. If fed any kind of ham domains, GetURI will look for and produce a list of false positives: domains listed in SURBL that appear in ham. New experimental code has been added to automatically determine the age of domains being checked, which has so far been a huge help for hand-classifying domains. This is done in the nicest way possible, but it uses public whois, and, as such, may violate some whois servers' terms of service, so --age must be specified explicitly. A new utility, uricat, has been added to produce simple lists of URIs found in one or more text files. Full change history: http://ry.ca/geturi/CHANGELOG Updated Sample results: http://ry.ca/geturi/results.html Documentation and download: http://ry.ca/geturi/ As always, your feedback is most welcome! - Ryan -- Ryan Thompson <ryan(a)sasknow.com> SaskNow Technologies - http://www.sasknow.com 901-1st Avenue North - Saskatoon, SK - S7K 1Y4 Tel: 306-664-3600 Fax: 306-244-7037 Saskatoon Toll-Free: 877-727-5669 (877-SASKNOW) North America -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

PROBLEM: WS.SURBL.ORG frozen
by Raymond Dijkxhoorn 04 Sep '04

04 Sep '04

Hello! Currently we are running with a somehow frozen ws.surbl.org list. We are experiencing hardware trouble with one of the SURBL machines. New updates will be processed, but most likely activated after we restore full functionality. The main SURBL site is not afffected, its only related to the WS updates. We are working hard to get the processing box back online. Bye, Raymond Dijkxhoorn - WS SURBL.
