[edit] Overview

Every hackerspace has a network to connect to the Internets, so does syn₂cat

Bring your laptop or use one of the available PCs, plug it in and off you go. There's also wireless LAN available.

[edit] Layout

Here's the current layout in fancy ASCII art.

[edit] IP

We provide both IPv4 and IPv6 connectivity in the hackerspace.

[edit] Wireless

There are several access points (APs) available for people to use. The APs do require authentication though some events feature a temporary open AP for visitors.

syn2cat is part of the spacefed project thus if you have an account with some other participating hackerspace, you may transparently connect using your account to the syn2cat wireless infrastructure.

Our main access points use WPA2-Enterprise meaning that you do have to authenticate using your syn2cat (or spacefed roaming profile) credentials.

Use the following settings:
Security: WPA2 Enterprise
Authentication: PEAP
Inner authentication: MSCHAPv2
Anonymous username/identity: anonymous@syn2cat.lu
Username/Identity: <syn2cat login>@syn2cat.lu
Password: <syn2cat password>

Be sure to use exactly those settings, else it will not work.

Tutorials can be found here.

[edit] SSL certificates

There are a total of three certificates of interest.
We use a chained CA, making for a total of two CA certificates:
rootCA (PEM)
subCA (PEM)

And lastly for your convenience, a bundle of both in one file:
rootCA-subCA bundle (PEM)

For completeness, but you probably don't need it, the certificate of the internal server at the space:
lusitania-certificate (PEM)

You should use the CA certificates when connecting to the WiFi network (see below, your software manual or ask somebody at the space how-to), but this is not a requirement.

[edit] OS compatibility

Linux works out of the box

in some versions end of 2013, eg ubuntu 13.04, was/is a bug where you need to remove the line system-ca-certs=true from to the relevant Network Manager config file (e.g. /etc/NetworkManager/system-connections/spacenet-kali).

Windows works out of the box
OSX works out of the box
iphone works out of the box
Android works out of the box
Symbian works fine (need to install CA certificates!, see earlier)
Maemo OS works out of the box

[edit] OS specific hints

[edit] Arch Linux

Howto: H4x0roam with netcfg and encrypted wpa supplicant config

[edit] Linux - WICD template

Save this as "/etc/wicd/encryption/templates/peap-mschapv2" and add the filename to "/etc/wicd/encryption/templates/active".

Note: outdated configuration, needs anonymous identity

name = PEAP with MSCHAPv2
author = syn<sub>2</sub>cat version = 1
require identity *Identity password *Password
optional ca_cert *Path_to_CA_Cert
-----
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="$_ESSID"
scan_ssid=$_SCAN
proto=RSN
key_mgmt=WPA-EAP
pairwise=CCMP
eap=PEAP
phase1="peaplabel=0"
phase2="auth=MSCHAPV2"
identity="$_IDENTITY"
password="$_PASSWORD"
ca_cert="$_CA_CERT"
}

After saving and activating the template, make sure to restart the wicd daemon and client. Next do a WiFi scan and configure an AP from the space, while using the newly created template !
You may specify a path to the CA certificate (see above)....you should do this actually, but still it's optional.

[edit] Linux - wpasupplicant

First install the H4x0roam SSL certificate chain:

mkdir -p /etc/ssl/h4x0roam
wget http://www.hackerspace.lu/certs/syn2catCA.crt -O /etc/ssl/h4x0roam/syn2catCA.crt
wget http://www.hackerspace.lu/certs/syn2catInfr.crt -O /etc/ssl/h4x0roam/syn2catInfr.crt
wget http://www.hackerspace.lu/certs/lusitania.lan.crt -O /etc/ssl/h4x0roam/lusitania.lan.crt
cat /etc/ssl/h4x0roam/syn2catInfr.crt /etc/ssl/h4x0roam/syn2catCA.crt > /etc/ssl/h4x0roam/combined-ca.pem
chmod 0644 /etc/ssl/h4x0roam/*

Please note that the 2 CA certificates have to be concatenated into a single file (this does only work with PEM certificated and not with DER certificates) to make wpa_supplicant accept tier 2 certifiactes (aka "certificates issued by a sub CA or intermediate CA").

Now add the following section to your /etc/wpa_supplicant.conf (you'll obviously have to fill in your own username and password):

network={
	ssid="h4x0roam-kali"
	key_mgmt=WPA-EAP
	eap=PEAP
	identity="YOUR HACKERSPACE USERNAME"
	password="YOUR HACKERSPACE PASSWORD"
	phase2="auth=MSCHAPV2"
	ca_cert="/etc/ssl/h4x0roam/combined-ca.pem"
	client_cert="/etc/ssl/h4x0roam/lusitania.lan.crt"
}
network={
	ssid="h4x0roam-pussy"
	key_mgmt=WPA-EAP
	eap=PEAP
	identity="YOUR HACKERSPACE USERNAME"
	password="YOUR HACKERSPACE PASSWORD"
	phase2="auth=MSCHAPV2"
	ca_cert="/etc/ssl/h4x0roam/combined-ca.pem"
	client_cert="/etc/ssl/h4x0roam/lusitania.lan.crt"
}

Note: outdated configuration, needs anonymous identity

Also make sure permissions are set correctly for wpa_supplicant:

chmod 0600 /etc/wpa_supplicant.conf

Warning: Please note that your syn₂cat credentials are stored in cleartext on the hard disk unless you are using an encrypted hard disk.

If wpa_supplicant throws error messages like

Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory

add the following line before the network={} section in your /etc/wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant

[edit] Nokia/Symbian phones and foo

Nokia/Symbian phones require you to install the CA certificates before they let you connect to a WPA-Enterprise network. They also mostly only support certificates in DER format.
So here go the CA certificate from above in DER format:
rootCA (DER)
subCA (DER)

[edit] Backend

Most of our services run on an LDAP backend. We have some information on our OID Registry.
