[CentOS] can I use CentOS as a antivirus / spam filter / HTTP AV gateway?
Hi all I've been thinking about using CentOS on a Dell R200 server and turn it into a firewall / network monitor / traffic shaper in our datacentre, instead of using a dedicated firewall device. One of the devices that I have been looking at, with my limited budget, is the D-Link DFL 860 - http://www.netdefend.eu/Product.aspx?m=15&ref=DFL-860 It provides AV, SPI, VPN, DOS, P2P, etc protection. Most of this can be done with Linux as well, but I'm not 100% sure about the AV part. How will I use / setup CentOS to check all traffic coming in & out (HTTP, SMTP, POP3, IMAP, etc) for virusses and clean them? We host both Windows & Linux servers, and I'm not too worried about the Linux servers, but Windows needs a lot of extra protection. -- Kind Regards Rudi Ahlers CEO, SoftDux Web: http://www.SoftDux.com Check out my technical blog, http://blog.softdux.com for Linux or other technical stuff, or visit http://www.WebHostingTalk.co.za for Web Hosting stuff

I've never attempted this myself, so I can't give you the exact recipe.

Don't tell Trend Micro you are scanning for viruses at the gateway ... they don't like that term :-D http://www.vnunet.com/vnunet/news/2219926/breakthrough-trend-micro-patent-barracuda -------------- next part -------------- A non-text attachment was scrubbed...
