DIY linux server

I would like to share information with the Habrosociety about how I assembled a home server.



From software on the home server the following set will “spin”:

• torrent client with web muzzle
• DHCP - we distribute ip addresses and network settings
• TFTP - for network boot
• OpenVPN - for going to the network from a netbook from untrusted networks
• FTP / Samba / NFS - network balls for access from home machines
• Radius - for WPA2 authorization
• DigiTemp - home temperature monitoring

Hardware

When choosing the hardware, there were several options:

• old comp
• mini-ITX self-assembly
• HP T5000 Thin Client
• thin client based on Neoware CA2

The first option was immediately discarded due to noise, dust and power consumption. The second one was ordered, while the components were on, I managed to change my mind (I wanted to reduce noise and power consumption to a minimum). As a result, thin clients of HP t5000 and Neoware CA2 were bought on Ebay . A month later, thin clients came and from two, after much deliberation, Neoware CA2 was chosen. It perfectly fits 2.5 'HDD and a second network card.

After completing, literally, Neoware CA2, I started installing Ubuntu 9.10 on it from the office TFTP server. Installation made the most minimal. If there wasn’t a set for network installation, I would install Debian from a USB CD-ROM and netinstall disk. I myself am an ardent fan of RHEL / CentOS, but I decided to put something from the debian family on my home server to expand my horizons.

Software

Torrent client and webmord

Now let's move on to installing the torrent client and webmords. The rtorrent + rutorrent bundle was selected, the installation from the repositories was checked immediately, because The "native" package was built without xmlrpc-c which extends the rutorrent functionality. Below, in fact, the script for auto-installation is rtorrent + rutorrent + lighttpd + php.

We install everything that is necessary for compiling xmlrpc-c, libtorrent, rtorrent We compile and "wrap" the package xmlrpc-c, libtorrent, rtorrent in .deb Unfortunately, rtorrent does not know how to work in daemon mode, so we will use screen Create a config and folders for sessions and finished torrent downloads, after which we start rtorrent. Now let's do the webmord rutorrent. Rutorrent requires a web server and php interpreter.
apt-get install checkinstall subversion build-essential make autoconf autotools-dev automake libtool libcurl4-openssl-dev libsigc++-2.0-dev pkg-config libncurses5-dev
apt-get remove rtorrent libtorrent11 libxmlrpc-c3 libxmlrpc-c3-dev libxmlrpc-core-c3 libxmlrpc-core-c3-dev

The web server is ready, now we will install rutorrent and some useful plugins for it. Now you can go to server_ip / rutorrent and start using it.
cd /var/www/
svn checkout rutorrent.googlecode.com/svn/trunk/rutorrent
cd /var/www/rutorrent/plugins/
svn checkout rutorrent.googlecode.com/svn/trunk/plugins/tracklabels
svn checkout rutorrent.googlecode.com/svn/trunk/plugins/cookies
svn checkout rutorrent.googlecode.com/svn/trunk/plugins/autotools
svn checkout rutorrent.googlecode.com/svn/trunk/plugins/erasedata
chown -R www-data:www-data /var/www/


DHCP

Now install the DHCP server and create a config for it so that the clients receive:
router 192.168.1.1
dns server 8.8.8.8
time server time.nist.gov
tftp server 192.168.1.1
and, for example, a fixed issue of 192.168.1.100 to the client with MAC address 00 : 1B: FC: 33: F0: 25 lines with option-150 are needed for my Cisco 7940 VoIP phone.
aptitude install dhcp3-server
cat >> /etc/dhcp3/dhcpd.conf < ddns-update-style interim;
not authoritative;

option domain-name-servers 8.8.8.8;
option subnet-mask 255.255.255.0;
option ntp-servers 192.43.244.18;

option option-150 code 150 = ip-address;
option option-150 192.168.1.1;

subnet 192.168.1.0 netmask 255.255.255.0 {
authoritative;
range 192.168.1.110 192.168.1.254;
option routers 192.168.1.1;
allow unknown-clients;

allow bootp;
next-server 192.168.1.1;

host shakirov-home {
option host-name "shakirov-home";
hardware ethernet 00:1B:FC:33:F0:25;
fixed-address 192.168.1.100; }
}
EOF
/etc/init.d/dhcp3-server restart


TFTP and network installation

aptitude install xinetd atftpd atftp

mkdir /tftpboot

cat >> /etc/xinetd.d/tftp < service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = --tftpd-timeout 300 --retry-timeout 5 --mcast-port 1758 --mcast-addr 239.239.239.0-255 --mcast-ttl 1 --maxthread 100 --verbose=5 /tftpboot

per_source = 11
cps = 100 2
flags = IPv4
}
EOF

/etc/init.d/xinetd restart

Now let's check if the tftp server is working. Everything is fine, now we will create netinstall sets for several OSs: Ubuntu karmic, Ubuntu lucid, Debian lenny, Debian sid, Debian squeeze, Fedora 13, CentOS 5.5, Mandriva 2010.0, Suse 11.2, Slackware 13.1, Hardware Detection Tool, memtest and MHDD. For this, I suggest using a slightly modified script that I took with HowtoForge . Now add SystemRescueCd to the PXE menu. Without much effort, you can add Acronis products to this menu, install and run Windows XP, and more. This is what our menu will look like: Continued in the next part. Namely:
root@dvr:~# echo bla > /tftpboot/123
root@dvr:~# atftp 127.0.0.1
tftp> get 123
tftp>
root@dvr:~# cat 123
bla


apt-get install lftp -y

wget itblog.su/tftpboot_installs.sh
bash tftpboot_installs.sh



wget "http://downloads.sourceforge.net/project/systemrescuecd/sysresccd-x86/1.6.3/systemrescuecd-x86-1.6.3.iso?use_mirror=citylan"

• OpenVPN server for “going” to the network from untrusted networks (for example, from a hotel)
• FTP / Samba / NFS network balls
• Radius for authorization of wifi clients
• DigiTemp the beginnings of a smart home, monitoring the temperature in the apartment and outside the window
• festival - talking alarm clock
• hosting from hosting

and the article will summarize a script that will install all this in “two clicks”.

I am pleased to hear comments and additions.
