Howto: Building Debian Linux server with CCcam (手动)

This how-to will cover the basic installation of Debian linux and getting CCcam up and running on it.

This How-to is still WIP by CC_Share

--Todo--

---------------------------------------

First download the netinstall cd of debian linux
You can download it from the following URL:
Link http://cdimage.debian.org/debian-cd/...86-netinst.iso

This will install the basic debian linux system on you're harddisk.
Boot the computer from the CD you just created.

Just press enter here to start the installation


Select the language you prefer


Select the country you're in. Based on the language it selects a default country


Here you can choose the keyboard layout. Make sure you select the proper layout otherwise installation might prove to be quite tricky.


Set up the hostname of you're server here. I prefer to set up the first part of my DYNDNS account info here.


Here you must enter the domain name. In the example above, you can see i put dyndns.org here


Next up is the partition guide. Here you must choose



Select the right harddisk. Usually in a stand-alone server, there will just be one entry


Debian will let you choose to have everything in 1 partition, or have seperate partitions for the important directory's. One advantage of having seperate partitions, You cannot fill the root system by accident if you upload a lot to the home directory. Linux will NOT boot correct , if the root filesystem is full


In the overview, You can check to see if all is set up correct before writing the changes to harddisk. Once you press finish, it will show you the next screen if you are really sure .


Once you select yes, It will write the changes to harddisk and format all partitions.


If Debian cannot guess you're timezone by looking at the bios, it will ask you for the timezone


Next you will have to enter the root password. Do not choose an easy to guess password if you want the server to be reachable from the internet. (if you want to use SSH for example to manage the server from work)



Next is setting up an account to use for FTP transfer.


Again, do not use a simple to guess password. This account can also be used for SSH


If you have the option, allways choose a network server.
Make sure you select a fast and stable one.
Usually univercity servers prove to be fast and stable


In the software selection screen, select base system and webserver


One of the last things it needs to know, is where to place the grub bootloader. Usually it is safe to place it on the MBR


Congratulations, You just installed a fresh new DEBIAN server.


As you might have noticed, during installation, debian uses dhcp to aquire an ip adress.
For a cardserver, it's not recommened to have it's IP adress handled by DHCP.
First thing we need to do is remove the DHCP and assign a static IP to the linux server

Assigning static IP
Log in as root with the right password
then type in the following command

vim /etc/network/interfaces

now remove the following line

iface eth0 inet dhcp

and replace it with

auto eth0
iface eth0 inet static
address 192.168.1.225
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1

These IP adresses might be different for you're situation.
Remember to replace them with the numbers you need.
You can save the file with the following commands

<esc>:wq

Once the file is saved, you can restart the network and check if you're linux server is running with it's new IP adress

/etc/init.d/networking restart
ifconfig

ifconfig should now look something like this

Installing SSH
Next thing that needs to be done is install a SSH deamon.
This will allow you to log into the cardserver from you're own computer and the server does not require a keyboard and monitor if you want to change something.

apt-get install openssh-server

Once SSH is installed, you can logout of the server,remove the keyboard and monitor as we don't need it anymore.

Getting Putty
We need to download putty so we can log in with SSH
http://the.earth.li/~sgtatham/putty/.../x86/putty.exe

Remove the CD-ROM drive from the apt-get mirror list:
To make sure the server does not need the CD-ROM anymore to update or install software, we need to remove it from the mirror list of apt-get.

vim /etc/apt/sources.list

now remove the lines that point to the CD-ROM drive and save the file.

Update apt-get software list
To make sure, you locally have a good software list available, you have to update the apt-get database

apt-get update

Installing FTP server
To be able to transfer files between you're computer and the linux server, a FTP server is needed.
During the installation it will ask you one question,. Answer it with "stand-alone"
This will consume a bit more memory but will prevent linux from spawning a new process every time you log in.

apt-get install proftpd

The server is now installed and all the needed files are in place.
Now it's time to get it ready for CCcam.
First thing we need to do is make 6 directory's and adjust the parameters.

mkdir /emu
mkdir /emu/cccam
mkdir /emu/script
mkdir /emu/log
mkdir /var/etc
mkdir /var/keys
chmod 777 /emu
chmod 777 /emu/*
chown <username> /emu
chown <username> /emu/*

The username started above is the username you created during the installation. This name is going to be used for file transfer.

Startup script for CCcam
To prevent from having to change directory all the time we're gonna place a script on the server so CCcam can be started from any directory on the server.

vim /emu/script/cccam

#!/bin/sh
CAMNAME="CCcam Server"
# end
 
# This method starts CCcam
start_cam ()
{
/emu/cccam/CCcam.x86 &
sleep 2
}
# This method stops CCcam
stop_cam ()
{
pkill CCcam.x86
}
case "$1" in
start)
echo "[SCRIPT] $1: $CAMNAME"
start_cam
;;
stop)
echo "[SCRIPT] $1: $CAMNAME"
stop_cam
;;
restart)
echo "Restaring $CAMNAME"
stop_cam
start_cam
;;
*)
"$0" stop
exit 1
;;
esac
exit 0

chmod 755 /emu/script/cccam
ln /emu/script/cccam /bin/cccam

Now you can simply start, stop or restart CCcam from any directory by simply typing

cccam start
cccam stop
cccam restart

Upload CCcam
Now use a FTP program to upload CCcam.x86 and CCcam.cfg to /emu/cccam

Making CCcam executable
Use putty again to give CCcam.x86 execution rights

chmod 755 /emu/cccam/CCcam.x86

Config update script
When you're running a big server, restoring connections can take some time then you change you're config file. I like to do my config changes once a day. I use this script to backup the old config and put the new config in place. This is done at 3am so my peers don't notice it and they don't suffer from a freezing picture every time you make a change.

vim /emu/script/configupdate.sh

#!/bin/sh
#Script to process new config and backup old one.
#Script designed and written by CC_Share
SOURCE=/emu/cccam
TARGET=/var/etc
FILE=CCcam.cfg
BACKUPDIR=/var/backup
CONFIGOLD=CCcam.old
if test -f $SOURCE/$FILE ; then
 echo "New Config Present"
 if test -d $BACKUPDIR ; then
  if test -f $BACKUPDIR/$CONFIGOLD ; then
  echo "Removing OLD config file from backup directory"
  rm $BACKUPDIR/$CONFIGOLD
  else
  echo "No OLD config to remove."
  fi
 
                if test -f $BACKUPDIR/$FILE ; then
                echo "Renaming Backup to old config"
                cp $BACKUPDIR/$FILE $BACKUPDIR/$CONFIGOLD
                rm $BACKUPDIR/$FILE
                else
                echo "No Backupfile present yet"
                fi
                if test -f $TARGET/$FILE ; then
                echo "Copying Original config to Backup directory"
                cp $TARGET/$FILE $BACKUPDIR
                rm $TARGET/$FILE
                else
                echo "No Original Config File Present!?!?"
                fi
 else
 echo "Backup directory does not exist."
 echo "making new directory"
 mkdir $BACKUPDIR
                if test -f $TARGET/$FILE ; then
                echo "Copying Original config to Backup directory"
                cp $TARGET/$FILE $BACKUPDIR
                else
                echo "No Original Config File Present!?!?"
                fi
 fi
 echo "Moving New config file to "$TARGET
 cp $SOURCE/$FILE $TARGET
 rm $SOURCE/$FILE
else
echo "No New Config present, Nothing to process"
fi
exit

chmod 755 /emu/script/configupdate.sh

Putting configupdate in crontab
To make sure the config update script will run at 3 am everynight, we can place it in the crontab.

cd /etc
vim crontab

and add the following line to it

00 3 * * * root /emu/script/./configupdate.sh >>/emu/log/configupdate.log 2>&1

This will run the script every day at 3am, and it's output will be writen in /emu/log/configupdate.log so you can check on occasion if all went well.

Putting CCcam in bootsequence

There's only one more thing to do. Add CCcam to the startup so it will start on the next reboot.

vim /etc/rc.local

and add the following line at the bottom

/bin/cccam start &

test the config update script created earlier to see if that works

/emu/script/./configupdate.sh

If it works, you can reboot the server and check if CCcam is running.
