Re: [Clamav-users] Idea for more timely virusdb updates
OK, here's my pitch I like the DNS idea as a way to push out just the version number of the update. This "pattern serial number" would be the current version of the CVD file. A record like this in tinydns: 'dbversion.clamav.net:447:600 would create a DNS TXT record for "dbversion.clamav.net" with a value of "447" with a TTL of 600 sec (10 minutes). I see no point in any more information being recorded. If freshclam were to initially do that DNS lookup, it could afford to look every 10 minutes instead of hourly, and would dramatically cut down on the amount of HTTP (or any other TCP) transactions required. I think all the comments about using SMTP or NNTP suffer the same problem as HTTP - they are no where near as fast or as natively "multicast" as DNS is - oh yeah - and it's UDP too. DNS natively "shares the load", whereas all other "load sharing" solutions would have to be created. So I'd envisage freshclam doing the DNS lookup, and if the "pattern number" TXT record returned is *different* (not smaller! DNS cache poisoning can affect this solution, so just choose DIFFERENT) than the current "pattern number", then it should check for an update. This has the advantage that it could just be a new bit of code added in front of the existing freshclam code. The TTL > 0 allows you to even cut down the load on the primary DNS servers. The ClamAV team should make a "policy" saying people aren't allowed to check for updates more often than every "TTL" seconds and this within freshclam would enforce it.

Then the clamav server doesn't Why use such an old protocol that isn't suited to binary transfers. I've already mentioned this jokingly, but I was half serious: I think setting up a bittorrent would solve a lot of the bandwidth problems. You would need some place to get the daily.cvd.torrent file, which seems to be about 170 bytes when I tried creating one yesterday (Small enough to fit base64-encoded in a DNS TXT record, if you insist, but I doubt that that is prudent to rely upon). Then you'd need a decent tracker, or a bunch of trackers, and at least one seeder per tracker. I guess that the current db.*.clamav.net hosts can easily host both a tracker and a seeder. If you then distribute a downloading clients that keeps seeding for just 1 hour (or until a preset share ratio was reached, say, 10x), you would very quickly take a HUGE load off the download servers... and everyone using clamav would automatically help the project by donating bandwidth for the updates.

That's one of the things that seems to be driving the size of daily.cvd up - updating main.cvd entails a massive distribution of files to the world. Perhaps a tiered approach to the update files, with main.cvd, monthly.cvd, weekly.cvd, daily.cvd, and hot.cvd The advantage there is that the really big update could be distributed very seldom - perhaps only with new code (the code generally has to be upgraded every few months to deal with a new threat anyway). If you had overlapping signatures between the files, you could add a fuzzy-factor into freshclam that it might not bring down the latest weekly/monthly if the other files overlap completely. That would distribute the load on the freshclam servers for the larger updates, and there would just be the very small daily.cvd (and perhaps hot.cvd) downloads. I like the idea of using DNS to signal the change - maybe just for hot.cvd. so, whenever a major virus breakout occurs, the new sig would be added to hot.cvd and the DNS TXT record changed. 10,000 users pulling down a 2-3K file is not terribly hard for a server with decent bandwidth -- Daniel J McDonald, CCIE 2495, CNX Austin Energy --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 ___ Clamav-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/clamav-users

Most MTAs I'm aware of (at least on the > unix side) can do this, I know qmail can for sure. Good idea. Taking it out of the milter allows for qmail/exim/postfix compatibility, and sending to a dedicated address saves the effort of processing every message (though presumably you're doing that anyway). With sendmail, you could add to /etc/aliases something like: clamav-updates | sigtool --add Before people get too excited about this idea, though, there are some issues that need to be fixed. Anyone know if it's really feasible for us to obtain a mailserver that can send out 2k emails to all (100,000?) users in a short (5-10 mins) time? Assuming those numbers are reasonable, that means 200 meg of data. Combined with SMTP overhead, it seems like it would be troublesome. Additionally, there are potential bandwidth issues if you consider we'd need to do that several times/day. Updating the "main" database is one concern. Sending out a 2-meg email to everyone seems like it might be too much load, but sending out the 1K email telling everyone to get it means the mirrors will get swamped. I can't think of a way around this, but hopefully someone else can? Also, this doesn't give much provision for removing "bad" signatures (that cause false positives) since it really just appends rules. We'd need to figure out a way to delete signatures also. I could imagine doing this by including a "null" signature, or using some other flag. Finally, there's the whole issue of multiplying your points of failure. If your current database is screwed, appending more to it will leave it screwed. And if you add stuff to it a few times a day, chances are it will get screwed up at some point. At least this issue has a simple fix: include an MD5 sum with the update which must match your MD5 sum after applying the update. If they don't match, you know something went wrong, either with this update or a previous one. (This has the danger that if the developers send an email with an incorrect MD5 hash, everyone will thrash the mirrors.) Note to the developers: please don't feel like you have to code up any of our random ideas. I'm just having fun brainstorming about how to optimize this process. I expect in another few days of discussion we'll have converged on a fairly sane idea. Damian Menscher -- -=#| Physics Grad Student & SysAdmin @ U Illinois Urbana-Champaign |#=- -=#| 488 LLP, 1110 W.

The mirror page talkes about the need for mirrors, about exponential growth, and how at least a 10mbit pipe is needed to host a mirror. It puts March 2004 traffic at about 120gig/month Some quick calculations: daily.cvd is about 150k compressed, 334k uncompressed -- let's say 50%. Greping the virses added for updated 447 gave me about 3k uncompressed -- so let's say 2k compressed, on the outside. For 2k of update, everyone downloaded 150k. That shows (at least for that update) only 1.3% of what was downloaded was needed. If only 1.3% of every update is actually needed, and people only downloaded what they needed, the traffic on the mirrors would drop from 120gig/month to 1.6 gig/month. If I am completely off by a factor of 10 -- say only 10% of every update is actually needed, traffic on the mirrors drops from 120gig to 12gig. There are a lot of assumptions here, but I would think ever reducing the load on the virus servers by half would be significant. == Chris Candreva -- [EMAIL PROTECTED] -- (914) 967-7816 WestNet Internet Services of Westchester http://www.westnet.com/ --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 ___ Clamav-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/clamav-users

Ok, this is turning into a scary beast. But we already have several mailing lists (clamav-users, for example) which can obviously handle a bit of a load. Might be interesting to concoct a specially-formatted message that the milter (or clamd itself) could recognize as a database update, and automatically append to its list of signatures. I'd imagine a format something like: ---gpg-cleartext-signed-message--- BEGIN clamd update 24.449 Worm.bagle.zz CCCEEFEFKL.. Worm.SkyNet.zz 14445577 ...

If so, it looks at the sequence number (24.449 in this case). If that's the next one in the series, it appends the rules to its database. If not, it assumes it lost a message somewhere and contacts a mirror via HTTP to get main 24 and daily 449. Doing something like this would push a lot of the distribution load onto sourceforge (which seems to get messages out to this list in about 1/2 hour). The gpg-signature prevents spoofing. And the sequence numbers keep everyone current. The major problems I see are getting clamd to recognize a message targeted for it, and the obvious problems of DoS attacks (someone sending spoofed messages that would suck CPU time decoding the gpg signature). Anyway, just another wild-n-crazy idea to throw out there. I'm guessing we're better off with the current method for now, but this might be an interesting possibility for the future.

One server notifying 10 servers is time consuming and sure - costs a lot of bandwidth... Lets assume that each notify takes 5 seconds... we have to have SOMETHING to "measure"... 1 server notifying 10 servers takes 50 seconds.

I wasn't proposing that it had to be done for free (not that it can't be with the factor tree I explained above). It might even reduce the cost of database distribution.

Then their own internal freshclam clients can poll their local authoritative server as often as they want, or use the same procedure to distribute to them (if they are full time connected that is). > In my opinion, the existing system is fine, and if you want > better, you should > talk to the clamav folks about setting up some sort of 'priority' Yeah, we could, but I don't think it needs that. And setting up an internal mirror doesn't address the response time of the updates, unless I start hammering the main freshclam every few minutes... and I just don't think that would be friendly. With the sort of hierarchical distribution I'm talking about, you could even use an ranking system to automatically organize the distribtion (while I'm on a roll ;-)... What I mean is that everyone would contact one of the "root" mirrors initially. In the request to be notified, it would indicate the number of clients it serves. If less than a certain number, then it could be referred to a child of the root server. If that child becomes unavailable it could contact the root again (at the next hourly polling time).

[Clamav-users] file handles leak in ClamAV (CVS 040731) ?
I've been using ClamAV for some time and am so happy you are providing this solution, especially with the latest Bagel variant that is going around. I am using the development version from CVS on 7/31/04, and have been sticking with it because it seems to have solved all of the memory leak problems from previous versions (0.75 and so on) However this morning I logged in and my system was completely out of file handles -- I couldn't reliably run anything, apps would fail, etc. I checked /proc/sys/fs/file-nr and found that the system had almost no file handles available. So I killed clamav and freshclam and "file-nr" went back up to ~3500 available. So it appears that there is a fairly significant file handle leak in this ClamAV version I am using. Has this been fixed following 7/31? Should I upgrade to a new version? thanks ! ed --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 ___ Clamav-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/clamav-users

I don't know that putting ALL of the records in DNS is necessary. The only reason I was putting the version number there was to allow quick, more frequent checks to see if you had the current version. It's possible to run DNS with very short TTL times, even 0. In terms of load on the servers: a smaller file would certainly help. I can see the simplicity of just haveing two files to grab being attractive. However, daily.cfg is now about 150k . I don't consider this big in the scheme of things, but if we are talking about hundreds or thousands of people trying to get the file, then the difference could be significant. Suppose there was a numbered file for each version that would 'upgrade' you from the previous version. IE, if I'm at 444, and current is 445, I grab 445.cvd. If I'm at 440, I grab 441.cvd, 442.cvd, through 445.cvd. Downside -- obviously harder to maintain. Upside -- someone who is staying constantly up to date is grabbing only a few bytes off the server at a time. I think this is simpler than putting all the data into DNS. I've also thought about rsync -- if putting the cvd files on an rsync server would lighten the load at all. == Chris Candreva -- [EMAIL PROTECTED] -- (914) 967-7816 WestNet Internet Services of Westchester http://www.westnet.com/ --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 ___ Clamav-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/clamav-users

For the list of supported options one can issue 'clamdscan -h' or 'man clamdscan'. Also, --disable-summary is _temporarily_ unsupported in CVS version (--no-summary is supported instead). It's due to an oversight - sorry. But before this message is delivered by the mailing list, it will be already corrected in CVS, most probably. A general tip: all "--disable-foo" options in clamscan and clamdscan are replaced with "--no-foo" form for conciseness. The longer form is of course still supported for backward compatibility, but it's more convenient to type less :-) . -- Tomasz Papszun SysAdm @ TP S.A.

Re: [Clamav-users] Idea for more timely virusdb updates
Mitch (WebCob) wrote: What about a deeper mirroring system? Perhaps one that supports notification? One of the things I like about BIND (not enough to use it, but still an admired concept ;-) is the way zones can be distributed... notification speeds things up if it works, polling creates a failsafe in which a missing notify doesn't cause the world to end... right, but as discussed below, generally bind servers don't have 100k people waiting for notifications and updates. Hourly polls is a good thing - but if the system worked both ways, the mirror could signal the end clients that it's time to download... those notifies could be send only to clients that had registered to receive it (an option in freshclam) and would not push the data, but trigger a freshclam pull. with that option, the 'clients' would either have to remain connected the entire time, which is completely not feasable, or somehow the database mirrors would have to either 'remember' who to notify, or have some sort of registry of people to notify (I can see how one might do this with a paid mirror service), and then send out notifications (even a single UDP packet to 100k servers could be quite bandwidth intensive. The architecture could work, yes, but it doesn't scale well, and I don't think the clamav team has the resources to do this sort of ass-kissing for free. They're already providing a wonderful service to the internet community, we cannot bite the hand that feeds us. Another problem with this notification is there are still the spikes when the notifications come out that EVERYONE AND THEIR BROTHER contacts the database mirrors for updates. Your solution doesn't solve any problems imposed by Christopher's idea, and actually introduces more. In my opinion, the existing system is fine, and if you want better, you should talk to the clamav folks about setting up some sort of 'priority' mirror, in which you would pay a fee for having more enhanced services, like notification, dns update polling, etc. And of course, proceeds (or at least a major part of) would go to the clamav team for being the most kick ass anti-virus product out there. I'm not sure how the official procedure would be to roll something like this out, but now that I think of it, I may just go about working on something like this. Gotta pay for my colocation somehow :) Tomasz, et al.: Please expect to see an email from me by the end of the work day tomorrow (or rather, today, but I haven't slept yet) It could provide faster update response and smooth out the spikes in download traffic, and could be used to maintain a larger set of mirrors... without increasing polling frquency... a new "freshclam server" could allow all larger users to easily run their own mirrors for internal distribution... I would think that most 'larger users' (5+ node mail server cluster) would already have an internal mirror. It's not difficult to do, and has been discussed on this list, and in the clamav documentation many times.
