Please note for Fedora and EPEL 7+ we use only systemd.
|
|
upstart and sysvinit only apply to EPEL 6.
|
|
|
|
A clamav-milter setup consists of the following three components:
|
|
|
|
* the clamav-milter itself
|
|
|
|
--> this is provided by the 'clamav-milter' package plus (alternatively)
|
|
'clamav-milter-upstart' or 'clamav-milter-sysvinit'
|
|
|
|
The main configuration is in /etc/mail/clamav-milter.conf and MUST
|
|
be changed before first use.
|
|
|
|
This can be enabled with: 'systemctl enable clamav-milter.service'
|
|
|
|
The -sysvinit package is managed by the traditional tools, but
|
|
-upstart requires modification of /etc/event.d/clamav-milter to
|
|
enable automatic startup. See comments there for more details.
|
|
|
|
* a clamav scanner daemon
|
|
|
|
--> this is in the clamd package (or on EL6:
|
|
'clamav-scanner-upstart' or 'clamav-scanner-sysvinit')
|
|
|
|
The daemon is configured by /etc/clamd.d/scan.conf (which MUST be
|
|
edited before first use).
|
|
|
|
This can be enabled with: 'systemctl enable clamd@scan.service'
|
|
|
|
The -sysvinit package is managed by the traditional tools, but
|
|
-upstart requires modification of /etc/event.d/clamd.scan to enable
|
|
automatic startup. See comments there for more details.
|
|
|
|
* the MTA (sendmail/postfix)
|
|
|
|
--> you should know how to install this...
|
|
|
|
When communicating across unix sockets with the clamav-milter, it is
|
|
suggested to use the /run/clamav-milter/clamav-milter.socket
|
|
path. You have to add something like
|
|
|
|
INPUT_MAIL_FILTER(`clamav', `S=local:/run/clamav-milter/clamav-milter.socket, F=, T=S:4m;R:4m')dnl
|
|
|
|
to your sendmail.mc.
|
|
|
|
|
|
EXAMPLE
|
|
=======
|
|
|
|
For clamav-milter, a possible setup might be created by
|
|
|
|
A) On the MTA (assumed hostname 'host-mta')
|
|
|
|
1. Add to sendmail.mc
|
|
|
|
| INPUT_MAIL_FILTER(`clamav', `S=inet:6666@host-milter, F=, T=S:4m;R:4m')dnl
|
|
|
|
2. Rebuild sendmail.cf
|
|
|
|
|
|
B) On the clamav-milter host (assumed hostname 'host-milter')
|
|
|
|
1. Install clamav-milter + clamav-milter-upstart packages
|
|
|
|
2. Set in /etc/mail/clamav-milter.conf
|
|
|
|
| MilterSocket inet:6666
|
|
| ClamdSocket tcp:host-scanner:6665
|
|
|
|
and all the other options which are required on your system
|
|
|
|
3. Enable clamav-milter.service:
|
|
|
|
| systemctl enable clamav-milter.service
|
|
|
|
Restart your system or execute
|
|
|
|
| systemctl start clamav-milter.service
|
|
|
|
4. Add something like
|
|
|
|
| iptables -N IN-cmilt
|
|
| iptables -A IN-cmilt -s host-mta -j ACCEPT
|
|
| iptables -A IN-cmilt -j DROP
|
|
|
|
| iptables -A INPUT -p tcp --dport 6666 -j IN-cmilt
|
|
|
|
to your firewall setup
|
|
|
|
C) On the clamav-scanner host (assumed hostname 'host-scanner')
|
|
|
|
1. Install clamd
|
|
|
|
2. Add to /etc/clamd.d/scan.conf
|
|
|
|
| TCPSocket 6665
|
|
| TCPAddr host-scanner
|
|
|
|
comment out possible 'LocalSocket' lines and set all the other
|
|
options which are required on your system
|
|
|
|
3. Enable clamd@scan.service:
|
|
|
|
| systemctl enable clamd@scan.service
|
|
|
|
Restart your system or execute
|
|
|
|
| systemctl start clamd@scan.service
|
|
|
|
4. Add something like
|
|
|
|
| iptables -N IN-cscan
|
|
| iptables -A IN-cscan -s host-milter -j ACCEPT
|
|
| iptables -A IN-cscan -j DROP
|
|
|
|
| iptables -A INPUT -p tcp --dport 6665 -j IN-csan
|
|
|
|
to your firewall setup
