Re: [SURBL-Discuss] Why is multi's rsync file so large?
by Rob McEwen (PowerView Systems) 11 Jan '07

Raymond Dijkxhoorn said: > In a era where you talk about gigabytes ram? Talking about this only costs > more ;) eh eh ... Excellent point. And I apologize in advance that this has now veered away from SURBL. (originally, I mistakenly thought this file size bloat might have been an SURBL problem... but it turns out there is NOT really any technical problems) ...but while we are "here"... On my server, I now have a large combination of various rsync subscriptions to various RBLs and DNSBLs that I use in my RBLDNSD. The problem is that my RBLDNSD program now uses a whopping 500MB of RAM. (again, not SURBL's fault... this is a combination of many different lists) So far, that isn't enough RAM to cause problems... but I noticed some sluggishness on my server today and, it turns out that sometimes, when RBLDNSD is "refreshing" its data, it re-builds an entire extra copy of the data in memory, along side the original copy. And this rebuilding can sometimes take several minutes to complete. Apparently, when done, it kills the old copy and start using the new copy. (again... I don't know why it has to rebuild the whole thing... but, then again, I don't know a whole lot about the inner programming of RBLDNSD) When this gigabyte of RAM is being used, I actually see a marked performance decline on my 2GB or Ram server. I know that one could argue that I ought to get more ram for my server... but I think instead I'll program a utility to periodically strip all these comments out of the records and point RBLDNSD to the stripped down versions. I'd be curious as to what the RBLDNSD performance and memory usage ends up being! Also, **getting back to SURBL** ...if you were to offer a "multi" file with comments stripped out, wouldn't this save bandwidth and rsync server resources if folks used that instead of the current offering?

>Just look inside the file and you will see? Since multi used shared lists >each comment line is added for each host seperately and not like the >seperate lists one comment field for all. OK. That makes sense... but I have a follow-up question. Does rbldnsd take up more memory by including that comment as the equivalent of a "text record" for DNS lookups that might attempt such a lookup against rbldnsd? If so, I'm thinking that, as beneficial as this might be in some scenarios, it sure probably uses a whole lot of extra ram on the server hosting the rbldnsd, correct?

Why is multi's rsync file so large?
by Rob McEwen (PowerView Systems) 10 Jan '07

Why is multi's rsync file so large? Am I doing something wrong with my rsycn? I'm thinking that multi should be, at most, the sum of the parts of the other lists... In fact, it should really probably should be **smaller** than the sum of its parts because of MUCH overlapping data getting consolidated in multi. 01/10/2007 02:03 PM 8,883 ab.surbl.org.rbldnsd 12/23/2006 11:53 AM 101,506 be.surbl.org.rbldnsd 01/10/2007 02:12 PM 5,760,311 jp.surbl.org.rbldnsd 01/10/2007 02:19 PM 75,027,410 multi.surbl.org.rbldnsd 01/10/2007 02:11 PM 6,826,763 ob.surbl.org.rbldnsd 01/10/2007 01:48 PM 330,910 ph.surbl.org.rbldnsd 01/10/2007 02:11 PM 1,435,961 sc.surbl.org.rbldnsd 07/09/2006 10:44 PM 0 sc2.surbl.org.rbldnsd 01/10/2007 01:03 PM 5,905,033 ws.surbl.org.rbldnsd 01/08/2007 03:44 AM 810 xs.surbl.org.rbldnsd 10 File(s) 95,397,587 bytes 0 Dir(s) 105,311,490,048 bytes free ...and some of these lists are no longer used in multi (or never were to begin with). Given the size of the component parts, shouldn't the multi file be somewhere around 10-20 MBs? Rob McEwen PowerView Systems rob(a)PowerViewSystems.com

Re: [SURBL-Announce] SURBL testpoint return values changed for multi.surbl.org

Maybe this should also be a test point for SURBL? -- -- Todd Vierling <tv(a)duh.org> <tv(a)pobox.com> <todd(a)vierling.name>

Dear Jeff Chan, Thank you for your answer. > The SURBL data come from many sources, as described at: Are each sources run as NPO? and Why are each sources selected?

Blacklisting 4th level domains possible? (dsl.connexus.net.au)
by Kelly Jones 24 Nov '06

24 Nov '06

Can SURBL blacklist 4th level domains? "connexus.net.au" is a perfectly valid domain, but subdomains of "dsl.connexus.net.au" are a bit suspicious. I got a spam referencing 106-147.dsl.connexus.net.au, probably someone running a webserver on their DSL connection. Reading http://www.surbl.org/implementation.html and http://spamcheck.freeapp.net/two-level-tlds makes me think only 2nd and 3rd level domains can be blacklisted. Am I wrong and/or is there any chance this will change? In theory, 3rd level domains like "connexus.net.au" could be added to two-level-tlds (ok, the name would have to change), and the implementation rule would be: 1) If the tail of your domain is listed in two-level-tlds, check one level deeper. Examples: if your domain ends in "guernsey.gg", SURBL-check "whatever.guernsey.gg"; if you domain ends in "connexus.net.au", check "whatever.connexus.net.au" 2) If the domain's not listed in two-level-tlds, check 2 levels deep (eg, "whatever.com").

Zone file snapshot?
by Kelly Jones 24 Nov '06

24 Nov '06

Does anyone have a recent snapshot of multi.surbl.org's zone file that they could email me? I don't need SURBL's rsync service or rbldnsd, just a recent snapshot.
