Install havp (HTTP Antivirus Proxy) in FreeBSD 7.1

by alamster in December 11th, 2008

Many of us still using internet explorer as main browser due to many factor, but much more related to our worksheet display. It’s in progress to make it more compliance to other browser such firefox and opera.

Another problem came up when spyware and virus spread more easier using IE. To prevent it from spread to other host I decide to install havp in junction with installed squid.

Squid already run in port 3128 and I want to install havp in recent FreeBSD 7.1 RC1

Here’s my steps :

1. Update ports to latest version using csup and install havp

cd /usr/ports/www/havp && make install

2. Install clamav

/usr/ports/security/clamav && make install

3. Edit rc.conf, add these lines :

clamav_freshclam_enable=”YES”

clamav_clamd_enable=”YES”

havp_enable=”YES”

4. Edit havp.config, My config :

USER havp
GROUP havp
DAEMON true

PIDFILE /var/run/havp/havp.pid
SERVERNUMBER 30
MAXSERVERS 100

ACCESSLOG /var/log/havp/access.log
ERRORLOG /var/log/havp/havp.log

LOG_OKS false

FORWARDED_IP true

X_FORWARDED_FOR true

PORT 8080

TEMPLATEPATH /usr/local/etc/havp/en

WHITELISTFIRST true

WHITELIST /usr/local/etc/havp/whitelist

BLACKLIST /usr/local/etc/havp/blacklist

SCANIMAGES false

ENABLECLAMLIB true
CLAMDBDIR /var/db/clamav
CLAMBLOCKMAX false
CLAMMAXFILES 1000
CLAMMAXFILESIZE 10
CLAMMAXRECURSION 8
CLAMMAXRATIO 250

ENABLECLAMD false

5. Copy havp english templates

mv /usr/ports/www/havp/work/havp-0.88/etc/havp/templates/en \

/usr/local/etc/havp

6. Update clamav, like this post.

7. Start havp

proxy# /usr/local/etc/rc.d/havp start
