Log File Rotation

If this is not done the log files will keep growing indefinitely.

Edit /etc/logrotate.d/asterisk

/var/spool/mail/asterisk
/var/log/asterisk/*log
/var/log/asterisk/full
/var/log/asterisk/dtmf
/var/log/asterisk/freepbx_dbug
/var/log/asterisk/fail2ban {
        weekly
        missingok
        rotate 4
        #compress
        notifempty
        sharedscripts
        create 0640 asterisk asterisk
        postrotate
        /usr/sbin/asterisk -rx 'logger reload' > /dev/null 2> /dev/null || true
        endscript
        su root root
}

TFTP

If you plan to use hardware SIP phones you will probably want to set up TFTP.

yum -y install tftp-server
nano /etc/xinetd.d/tftp

change server_args = -s /var/lib/tftpboot
to server_args = -s /tftpboot

change disable=yes
to disable=no

mkdir /tftpboot
chmod 777 /tftpboot
systemctl restart xinetd

firewall-cmd --permanent --zone=public --add-port=69/udp
firewall-cmd --reload

MPG123

This is used in combination with sox to convert uploaded mp3 files to Asterisk compatible wav files.

cd /usr/src
wget http://ufpr.dl.sourceforge.net/project/mpg123/mpg123/1.22.4/mpg123-1.22.4.tar.bz2
tar -xjvf mpg123*

cd mpg123*/
./configure --prefix=/usr --libdir=/usr/lib64 && make && make install && ldconfig

Digum addons

Password protect http access

A simple way to block scanners looking for exploits on apache web servers.

mkdir -p /usr/local/apache/passwd
htpasswd -c /usr/local/apache/passwd/wwwpasswd someusername
htpasswd -c /usr/local/apache/passwd/wwwpasswd someotherusername

nano /var/www/html/.htaccess

# .htaccess files require AllowOverride On in /etc/httpd/conf/httpd.conf
AuthType Basic
AuthName "Restricted Access"
AuthUserFile /usr/local/apache/passwd/wwwpasswd
Require valid-user

Alternatively, the above .htaccess config can be added to /etc/httpd/conf/httpd.conf or as a separate file in /etc/httpd/conf.d/  as follows.

<Directory /var/www/html>
AuthType Basic
AuthName "Restricted Area"
AuthUserFile /usr/local/apache/passwd/wwwpasswd
Require valid-user
</Directory>

Whitelist protect http access

If http access is only required from certain IP addresses.
NOTE: Apache 2.4 以後才支援這功能

Edit /etc/httpd/conf.d/whitelist.conf

<Location />
  <RequireAny>
  ## Uncomment the following line to disable the whitelist
  #Require all granted

  Require ip x.x.x.x
  Require ip x.x.x.x x.x.x.x x.x.x.x
  Require ip x.x
  Require ip x.x.x.0/255.255.255.0
  Require host somedomain.com
  #
  ## See http://httpd.apache.org/docs/2.4/mod/mod_authz_host.html for more examples
  #
  </RequireAny>
</Location>

舊版 Apache 設定
NOTE：確定網站目錄有 AllowOverride All 設定

.htaccess：

order deny,allow
deny from all
# Alang's IPs
allow from 123.123.123.1
allow from 111.222.222.2
allow from 192.168.99.
