DebConf9/LAN

DebConf9 LAN and WLAN

Locations

• Internet connection comes in at the room "Informática" (is the Organizers room).
• The connection then goes to the server room opposite of the hacklabs from where all other connections including wireless routers are fed.

WLAN

• The ESSID of the official wireless network are "debconf" and "debconf_wpa". The PSK for "debconf_wpa" is "debconf9".
• The ESSID "debconf9" was also official, but has been shut down when most "debconf" routers were spread out and working.

Access Points Configuration

We will use the WAN interface for managing purposes.

LAN port number 1 will be used to connect the AP to the main switch.

Technical details

• All wireless routers are configured to work as bridge between their internal switch ports (not WAN port) and the WLAN port. They're based on OpenWRT Kamikaze version 8.09.1 with kernel 2.4 (for the Broadcom-based Buffalo) and kernel 2.6 (for the Atheros-based Fonera).
• All wireless routers have a sticker with a number on it. There internal IP address is 192.168.145.$thisnumber.
• The wireless routers are Buffalo WHR-G54S and Fonera 2100/2200/2202 routers .The AP labels are composed by a letter B if it's a Buffalo router or F if it's a fon router.
• More of the newer routers are only providing debconf_wpa. If this is a problem for you come and talk to us and we might be persuaded to make more access points open.

Francisco de Sandes

Unfortunately the hostel network at Francisco de Sandes is not great, so it has been necessary to install some additional basic services. In some parts of the building there is now an open network with the essid 'dc9_fds'. In most of the rest of the building there is a network called 'fdebconf_wpa' with the PSK of 'debconf9'. Due to the nature of the provided connectivity there is also an essid of 'tdebconf_wpa' (same PSK as elsewhere) which is a completely separate connection, so if you can get onto it you should abuse that bandwidth as much as possible.

You're also able to use the hostel network, via their a captive portal, but you might need a username and password from the front desk.

==> Is there a single username/password pair which we can all use so someone can post it here or do we need our own?
