DansGuardian or ClamAV issue?


Hi all,

I am new to the forum and only know the basics of linux. I just started a new job and here we use DansGuardian on our lab machines to regulate usage. I know absolutely nothing about DansGuardian other than to check the status and start/restart services.

A strange thing is happening on the lab computers: users can access some websites but not others. For instance, yahoo is accessible but google is not. This screen displays on the unavailable websites:

DansGuardian Antivirus Patch - Error during scanning

Error message: 'Error connecting to clamav daemon'
-------------

I have tried refreshing by running the 'freshclam' command, and the following output appears:

Executing /etc/rc.d/init.d/freshclam start ..

did you read the ClamAV FAQ as it told you to ?
http://www.clamav.net/support/faq/

First thing it's asking you to do is update your clamav install because you are running an old version.


is clamd running ? if not then it wouldn't be able to connect to it.. that could account for the error at the end..
ps aux | grep clamd

yes, i've read the faq and the wiki as to how i would install the new version, however i don't know how i could access the terminal to do so. what i am accessing is the Webmin GUI for DansGuardian. i am also a newbie and i truly only know the basics of linux.

and yes, clamd is running. i also tried restarting the service but i still keep getting the 'cannot connect' error

is there a way i can just temporarily stop dansguardian so the users can access the internet until i can figure out how to update clamav in the meantime?

thanks for replying!

What OS is Dansguardian installed on ?

What how-to did you follow to install and configure dansguardian ?

I think it's installed on Windows. (I just have a link to an IP address that is the GUI for it)

I really have no idea how it was installed or configured.. I just started at the company a week ago and they guy I replaced left and I have no contact with him. Also the place is a non-profit with no technology budget so I can't hire a consultant for help..

Thanks so much for the quick response!

well... when you log into the dansguardian box with webmin the page should be displaying the OS information, that is the first page that is displayed in webmin, system information.


example
Code:
System hostname 	mail
Operating system 	Debian Linux 3.1



I don't think dansguardian can be installed on a Windows box.. Although I could be mistaken.

On the Operating System and Environment page it says the "Operating system according to Webmin" is CentOS Linux 4.4", and the internal code used by Webmin is redhat-linux 12.0

You should see if you can ssh into the centos machine and update clamav, use putty on a windows machine if that' all you have available

yum update clamav

you should also setup a Linux box of your own so ytou can learn it if you are going to be managing this system.

Concur with that last suggestion. Here's a very good Linux tutorial (free): http://rute.2038bug.com/index.html.gz
