Name

Internal Server

Description

The HS need to be tidy in his IT, centralized everything

Goal

Provide a server internal to the hackerspace.

Obstacle

Requirements

The services that would be nice to have are listed below.

Maybe find a mini rack to put the switch on it and keep everything clean.

Services available only from inside the HS

• MPD Daemon
• ssh key updater (put the key on a single machine which then upload the key on guest1, guest2)
• OpenLDAP Server for personal identification (wifi and login into guest1 and guest2, wiki, ftp)
• radius server for the wpa
• Sync guest1 and guest2 to be the same and to share all the software installed (sync the key too)
• screen session for share coding
• Samba shares
• NFS share
• A pulse server to output the sound of Guest1 and Guest2 on the big speaker (easy conference tool, easy way to look at vids :))

• other ideas : http://hackerspaces.org/wiki/Hackerspace_Software

Services available from anywhere

• FTPServer on ssl or ssh
• Git server (gitolite ?)
• IP over DNS server (http://thomer.com/howtos/nstx.html, http://code.kryo.se/iodine/ seems better as it support authentication)
• SSH or openvpn to access the hackerspace for ctf or other event
• virtualisation for testing stuff
• bug tracker

The internal requirement for the server

• Less than 40 Watt on load
• RAID for fallback
• Easy backup
• Encryption of some directory would be nice to have
• at least 8 Go of ram

Propositions

Gcmalloc can provide simple atx cases and the power supplies are legion around, so I'm not counting them in the price The first try is :

Cheap
	Motherboard
		Intel D525MW, Atom D525 Dual Core, Mini-ITX
		85 CHF
	HDD
		1 * 1 To
			Hitachi green
			50 CHF

	TOTAL
		135 CHF

Middle 
	Motherboard
		Jetway JNC9C-550
                http://www.jetway.com.tw/jw/ipcboard_view.asp?productid=781&proname=NC9C-550-LF
	        109£
	HDD
		Similar to High
	TOTAL
		160+100+120=380 CHF
	without the raid
		160+100+60=320
	without the ssd 
		160+60=220
		

High
	Motherboard 
		JNF81-T56N
		http://www.mini-itx.com/store/~JNF81-T56N 
		139£
	HDD
		40 Gb ssd
			http://digitec.ch/ProdukteAuswahl2.aspx?knr=2075
			100 CHF
		2 * 2To Hard drive
			60 CHF per piece  120 for both

	TOTAL
		160+100+120=380 CHF
	without the raid
		160+100+60=320
	without the ssd 
		160+60=220

On the month of november, A 2 To HDD cost around two time my arm (around 240 CHF). All that is caused by the flood in Thailand. We should wait for the price to calm down a bit Freestorm proposed to give freely 160Go Sata HDD. so:

Cheap
	Motherboard
		Intel D525MW, Atom D525 Dual Core, Mini-ITX
		85 CHF
	HDD
	TOTAL
		85 CHF

Middle 
	Motherboard
		Jetway JNC9C-550
                http://www.jetway.com.tw/jw/ipcboard_view.asp?productid=781&proname=NC9C-550-LF
			109£
	TOTAL
		160+100=260 CHF
	without the raid
		160+100=260
	without the ssd 
		160=160
		

High
	Motherboard 
		JNF81-T56N
		http://www.mini-itx.com/store/~JNF81-T56N 
		139£
	HDD
		40 Gb ssd
			http://digitec.ch/ProdukteAuswahl2.aspx?knr=2075
			100 CHF

	TOTAL
		160+100=260CHF

We can then easily go to the JNF81-T56N motherboard. the resulted prices are as following:

• JNF81-T56N 139GBP + 40GBP livraison --> 257.457 CHF
• TVA + douane --> ~50 CHF (estimation)

• Corsair ValueSelect 4GB SO-DIMM, DDR3-1333, CL9 --> 24 CHF

We need around 186 CHF to end this project.

Schedule

The goal is to have it before the beginning of january 2012

• 09 november 2011 : we made some benchmark on a atom N270, with heavy load on an apache server, sshd daemon, mpd and vsftp. Everything is working flawlessly :) so we can go for the dual core atom. The ftp connexion were around 15 MByte per connexion. We need at least 8 Go of ram for that.
• 01 december 2011 : The motherboard JNF81-T56N was ordered, should be there 6 days later.
