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
