Title: Re: Re[2]: [sniffer] Sniffer Updates
I made this one, which is probably also somewhere on the sniffer site. Change directories and keys for your use:
d:
cd\Batch Files\Sniffer
 
wget http://sniffer:[EMAIL PROTECTED]/Sniffer/Updates/<key>.snf -O <key>.snf.gz --timestamping --header=Accept-Encoding:gzip
 
gzip -d -f <key>.snf.gz
 
:Check
fcom32 "c:\mdaemon\sniffer\<key>.snf" "d:\batch files\sniffer\<key>.snf"
if errorlevel 1 goto Test
goto :Done
 
:Test
snf2check.exe <key>.snf <password>
if errorlevel 1 goto Done
 
copy /y <key>.snf c:\mdaemon\sniffer
copy /y <key>.snf <key>.old
 
:Done
 
Check for wrapping by your e-mail client! I've put an empty line between every line, to make sure you see what belongs together. Next to the --timestaping feature of wget, I also use fcom32.exe to see if the file is really different than the one before. This example also uses gzip!

Does anyone have any good instructions on how to modify your update scripts to use gzip?

Automate harassment reminders to those of us not using it. :)

I think I'll go enable gzip tonight

Also, I did some incantations on the log (grep, awk, uniq etc) and
came up with just under half of our customers downloading their
rulebase between 1200 and 1300 today. That's between 2 and 3 times as
many as should have done it ;-) -- so the backlog is explainable.

This kind of thing happens for lots of reasons and there are a lot of
ways to mitigate the problem.

A big one on the list - certainly - is using the gzip capability. With
only 5% of folks using this and average compression ratios well above
50% there is plenty of room to "make a big dent" in this.
