amavisd-new

故有って再びウイルススキャンを稼働させることにしてみる。

まずは、portsを最新にして、/usr/ports/security/amavisd-new/Makefile を

AMAVISUSER?=	clamav
AMAVISGROUP?=	clamav

としておく。で、

guard:root {131} % portupgrade amavisd-new-2.5.3,1

するが、

===>   p5-Net-DNS-SEC-0.15_1 depends on package: p5-Net-DNS>=0.64 - not found
===>   Found p5-Net-DNS-0.61, but you need to upgrade to p5-Net-DNS>=0.64.
*** Error code 1

Stop in /usr/ports/dns/p5-Net-DNS-SEC.
*** Error code 1 

Stop in /usr/ports/dns/p5-Net-DNS-SEC.

などと方々でエラー・・・・

いろいろモジュールが古いとのことで、エラーを手動で解除してゆき

*******************************************************************
To use amavisd-new, you need to install at least one virus scanner.
The following virus scanners are available in the FreeBSD ports
collection:

/usr/ports/security/vscan      McAfee VirusScan
/usr/ports/security/clamav     Clam Antivirus
/usr/ports/security/f-prot     F-Prot Antivirus
/usr/ports/security/drweb      DrWeb antivirus suite

Enable amavisd-new in /etc/rc.conf with the following line:

   amavisd_enable="YES"

You can set the pidfile, if you do not use the default path:

   amavisd_pidfile="/var/amavis/amavisd.pid"

Optionally enable amavisd tmp ram disk with: (DISCOURAGED!)

   amavisd_ram="512m"

If you have installed and want to use the amavis sendmail milter interface,
you need the following additional line in /etc/rc.conf:

   amavis_milter_enable="YES"

If you have installed and want to use the p0fanalyzer interface,
you need the following additional lines in /etc/rc.conf
(with modifications according to your needs):

   amavis_p0fanalyzer_enable="YES"
   amavis_p0fanalyzer_p0f_filter="tcp dst port 25"

You can pass another command line options to p0f daemon by setting
amavis_p0f_daemon_flags and to p0f-analyzer.pl by setting
amavis_p0fanalyzer_flags.

Configuration templates are available in /usr/local/etc
as amavisd.conf-dist, amavisd.conf-sample, amavisd.conf-default
and amavisd-custom.conf-dist.
Documentation is available in /usr/local/share/doc/amavisd-new.
