Hello sherpya,

On the local db-mirror i have the *.cvd and *.cdiff. The daily.cvd is not the actual, but the *.cdiff are wgetted when there are newer versions.
This way i want to minimize the download.

freshclam.conf:
Code:
DNSDatabaseInfo current.cvd.clamav.net
ScriptedUpdates yes
DatabaseMirror local-IP
In the local net there are XP, NT 4.0 SP6a and linux-machines.
On the XP and linux all is okay: freshclam gets the *.cvd, and with the newer *.cdiff the *.cvd are translated to *.inc\.

On the NT4 there are 2 Problems:
1) the *.cvd are NOT translated, i have to do it "manual" (helper-script) with sigtool.
2) if there is an *.inc\ on the client, the scripted updates go on, but just to the version of an *.cvd on the local mirror.
Newer *.cdiff are ignored.
So the version-information of current.cvd.clamav.net seems to be ignored. (i can indeed evaluate with 'nslookup -type=TXT' on the NT4-machines)

So you see, if i set freshclam.conf to:
Code:
DatabaseMirror database.clamav.net
the scripted updates for the NT4-clients go on, but just because there is the actual daily.cvd everytime.
And not of the information from current.cvd.clamav.net.

to minimize downloads I suggest you to use only .cvd and not cdiffs since only freshclam has the ability to unpack/apply another solution
is use a proxy that caches cdiffs
I've disabled dns query on nt4 since the os does not provide facility do to txt dns query and also
there are no realable ways to detect the ip of the dns
does someone have suggestions about this?

you can look here:
http://clamwin.svn.sourceforge.net/viewvc/clamwin/trunk/clamav-release/contrib/msvc/src/dnsquery.c?revision=1400&view=markup http://clamwin.svn.sourceforge.net/viewvc/clamwin/trunk/clamav-release/contrib/msvc/src/dnsquery.c?revision=1400&view=markup
I use 2 different ways 1 using api (win2k+) the second is query directly the dns (win98) but I need to known the configured dns
