How to protect your cccam s*rver with fail2ban in 4 steps installation

'' If you server slow down or have high network load or high consummation on ram or cpu. You need to jail unwanted peers.

After following modification my server stop to freeze.

My system is Ubuntu server 11.10 32bit, cccam 2.1.3

1. Prepare your system (all commands are started like normal user)

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install fail2ban nano bsd-mailx
$ sudo touch /var/log/cccam.log
$ sudo chmod 755 /var/log/cccam.log

Change cccam options in your cccam start up script to

./CCcam.x86 -d > /var/log/cccam.log &

2. Configuration

- run command:

$ sudo nano /etc/fail2ban/jail.conf

- change

backend = auto

to

backend = polling

- after

# action, port, logpath, etc) in that section within jail.local

add and change 1234 with your cccam port after save and close file.

[cccam_sign]

enabled = true
port = 1234
filter = cccam_sign
logpath = /var/log/cccam.log
maxretry = 10
bantime = 86400

[cccam_double]

enabled = true
port = 1234
filter = cccam_double
logpath = /var/log/cccam.log
maxretry = 10
bantime = 3600

[cccam_bad]

enabled = true
port = 1234
protocol = tcp
filter = cccam_bad
logpath = /var/log/cccam.log
maxretry = 10
bantime = 1800

[cccam_ill]

enabled = true
port = 1234
filter = cccam_ill
logpath = /var/log/cccam.log
maxretry = 3
bantime = 12000

[cccam_fail]

enabled = true
filter = cccam_fail
action = iptables-allports[name=cccam_fail2ban]
sendmail-whois[name=cccam_fail2ban]
logpath = /var/log/fail2ban.log
findtime = 604800
bantime = 604800

$ sudo nano /etc/fail2ban/filter.d/cccam_bad.conf

3. Reboot the system.

4. Login into system and make running checks.

- run command:

$ tail -f /var/log/cccam.log

If you see displayed content so that mean cccam log working well.

- run command:

$ tail -f /var/log/fail2ban.log

That will display banned ip addresses from fail2ban if you have any unneeded peers . ''
