SquidGuard is a URL redirector used to use blacklists with the proxysoftware Squid. There are two big advantages to squidguard: it is fast and it is free.
Maildrop
Primary tabs
Prerequisites
Maildrop requires PCRE to be installed:
cd /extra/src
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.37.tar.gz
tar zxvf pcre-8.37.tar.gz
cd pcre-8.37
./configure --enable-utf8
make
make installVersion 2.8.1 requires the Courier Unicode Library
cd /extra/src
wget http://iweb.dl.sourceforge.net/project/courier/courier-unicode/1.3/courier-unicode-1.3.tar.bz2
tar jxf courier-unicode-1.3.tar.bz2
cd courier-unicode-1.3
./configure
make
make installYou also need to add the library files to LD_LIBRARY_PATH:
echo "/usr/local/lib" > /etc/ld.so.conf.d/locallibs.conf
ldconfigMaildrop installation
Install the gdbm-devel package:
yum -y install gdbm-develThen download and install maildrop:
cd /extra/src
wget http://iweb.dl.sourceforge.net/project/courier/maildrop/2.8.3/maildrop-2.8.3.tar.bz2
tar jxvf maildrop-2.8.3.tar.bz2
cd maildrop-2.8.3
./configure --enable-maildrop-uid=vpopmail --enable-maildrop-gid=vchkpw
make
make install-stripMaildrop Logging
Patrick McDonald came up with a good way of setting up Maildrop's logging to use multilog. His Maildrop with multilog page details the installation as well as why he did it this way:
Maildrop provides a logging functionality. This functionality allows you to log what actions maildrop is taking with your messages and where you want it to write. There are a couple of problems with the maildrop logging functionality. First, there is no means to limit the size of the log file. This means the logfile could grow to fill the partition and/or filesystem. Second, it does not possess the ability to rotate files by criteria. Programs such as logrotate while capable of handling these problem, do not posses an automatic restart capability and are not OS agnostic.
Patrick's method requires creating a logger service using a named pipe and having maildrop log to the named pipe. For the purposes of this example, the named pipe will be "/tmp/log-maildrop". To create the maildrop-logger service:
mkdir -m 1755 /var/service/maildrop-logger
mkdir -m 755 /var/service/maildrop-logger/log
cd /var/service/maildrop-logger/log
wget -c --no-check-certificate http://www.antagonism.org/scripts/log-run
mv log-run run
chmod 755 run
cd ..
wget -c --no-check-certificate http://www.antagonism.org/scripts/log-maildrop
wget -c --no-check-certificate http://www.antagonism.org/scripts/pipe-watcher
wget -c --no-check-certificate http://www.antagonism.org/scripts/maildrop-logger-run
mv maildrop-logger-run run
chmod 755 pipe-watcher log-maildrop runCreate the symbolic link to start the service:
ln -s /var/service/maildrop-logger /serviceWait about 10 seconds then confirm that the service is running:
svstat /service/maildrop-loggerTo really confirm that it is running, in one shell window, watch the maildrop-logger log file:
tail -f /service/maildrop-logger/log/main/currentIn another shell window, echo some text onto the named pipe /tmp/log-maildrop. You should see the text in the service log:
echo testing > /tmp/log-maildrop- Log in to post comments
