David,
Freshclam has a daemon mode, and can be run explicitly from the command
line or from a cron job. In your case the cron entry appears to be
commented out so it's probably running in daemon mode. It will likely do
the same thing in either case.
Looks like you have some decisions. Whether or not to upgrade clamav,
and whether or not to upgrade the rest of the system too. Perhaps
someone who has more experience with Fedora that I can comment on this
given the systems you have and your [limited] experience with Linux.

Karl,
Ran "freshclam -v" on both. Here's the shortened:
Warning: ClamAV OUTDATED, Local Version 0.88.7, Recommended 0.93
Main.cvd is up to date, Version 46, sigs 231834
Warning: Current functionality level =10, recommended = 26
Daily.cvd is up to date, Version 7269, sigs 70227
When I ran "crontab -l" there is a freshclam line:
#33 * * * * /usr/bin/freshclam --quiet -l /var/spool/amavisd/clam-update.log
Looks like I need to upgrade ClamAV? Looking in the FAQ for the upgrade
instructions - no idea if it was installed from Sources or Packages.
**And I am fairly a big NOOB!! I recognized the "#" from the command line (familiar from some DOS and Cisco work), but if you didn't tell me that I'd probably have typed it...

Hi David,
You should see the file index.html in the directory where you typed the
command, and you can delete that file.
Next thing to try is to type:
# freshclam -v
at a command prompt (and see * below). You probably will need to be root
to do this. The -v switch means verbose output. See if any errors show up.
Another thing to do is type (as root):
# crontab -l
This will list all the "cron jobs" run as root. These are jobs run on
the specified schedule. See if there is anything having to do with the
clamav database update. If the system uses freshclam it will not show up
there, but if it's using another updating technique you may see it.
* I don't know how noob you are, but in case you aren't aware the '#' in
the above command represents the last character of a root command prompt
(and you don't type the pound sign when entering the command). If I had
used a '$' instead of '#' it would have represented a non-root command
prompt.

Thanks Karl! I typed the command and (shortened) it says it connected OK - to 64.142.100.50:80. Another line listed it at 100% in 87.5 MB/s and save 1163/1163.

Please bear with me - I'm a Linux WAY newbie and basically don't know jack... I inherited 2 email gateway (Postfix) servers (primary and backup) running Fedora 6 and ClamAV. Recently both started reporting daily errors:
ERROR: Error while reading database from db.US.clamav.net
ERROR: Can't download daily.cvd from db.US.clamav.net (IP: 199.239.233.95)
The IP address varies - guess that's the pool of servers it's connecting to thru clamav.net. From all indications, both servers can connect to the internet - email is still getting thru.
So is this something I should be concerned about? Or does ClamAV, if it fails
on one server, go to the next one and download the CVD? I tried reading the
ClamAV manual, but with not knowing how to really use Linux (via command
line)...it's almost Greek to me... J I did find (in the manual) where I can
change how and where they try to download the CVD from, but I can't for the
life of me (time and all limiting this) how to get to that point. And yes,
trying to get a Linux class to be my next goal!!!
Any ideas, easier "How To" reading, help, etc. would be greatly appreciated!
Thanks!
David,
It's a concern only because your anti-virus database is not being updated.
Since you have two systems and neither one can get the database, it
sounds like it may be a firewall issue. Freshclam is probably the
program used to downloads updates. It uses http so that needs to be open
in your firewall(s). It's possible outgoing port 80 connections aren't
being allowed since that's not usually required for a mail server. At a
command prompt in one of your mail systems, type:
wget db.US.clamav.net
Then hit return and see what happens. It should download index.html from
that site and put it in the directory where you ran the command from. If
this doesn't work, look for a firewall issue.
Post the results if you want.
Karl
