IETF 87 Network Information - Berlin, Germany

Terminal Room

The Terminal Room is located in Kopenick I/II and is open 24 hours a day beginning Sunday, 28 July, 2013 at 16:00 and ending on Friday, 02 August, 2013 at 15:00. A help desk is being provided, hours are listed below.  The room itself consists of approximately 100 seats providing some wired access and 220v EU power ports. There is also an HP Officejet Pro 8600 (HP994A15) printer available. Please note that this terminal room has, in fact, no terminals, PCs or other user-accessible machines. It is simply a place to get power, wired Internet access, help desk support, or print documents.

When using the Ethernet connections in the Terminal Room, IPv4 addressing is provided via DHCP. Please use Dynamic Auto-configuration for IPv6. A stateless DHCPv6 server will provide network information.  To cut down on the mess, ethernet cables have not been installed to every seat in the Terminal Room. If you need a cable, please ask at the Help Desk.

Please note that at the request of the IETF Chair, demonstrations are no longer permitted in the Terminal Room.

Help Desk
A help desk is being provided and will be manned the following hours: 

 Sunday        || 16:00 to 19:00
 Monday        ||  8:00 to 20:00
 Tuesday       ||  8:00 to 18:00
 Wednesday     ||  8:00 to 20:00
 Thursday      ||  8:00 to 20:00
 Friday        ||  8:00 to 15:00

NOC and Ticketing
There are several ways to communicate with the NOC staff. 
1. Submit a new trouble ticket via the trac web interface at http://tickets.meeting.ietf.org/newticket . Filling in the following fields: "My MAC Address", "My Current Location", and "My OS" may expedite ticket processing. If you have an existing account on http://tools.ietf.org you can use your established credentials (email address and tools password) log in.
2. Send an email to tickets @ meeting.ietf.org with as much detail regarding your issue and configuration as possible. 
3. If you're on site and need direct network assistance (i.e - you have no network) please go to the helpdesk, which is located in the Terminal Room.
4. Use the Jabber room at noc @ jabber.ietf.org to report issues or communicate with the NOC. 

You can also use trac to review outstanding tickets before reporting an issue or to update outstanding tickets.

Network Basics

External Connectivity
The IETF 87 network connects to the Internet via two 1Gb/s links, provided by Deutsche Telekom. The entire event is addressed out of the block for IPv4 and 2001:df8::/32 for IPv6. IPv6 is native and is supported. We are supplying bandwidth for the conference space, public spaces, in-room wireless and wired connections at the Intercontinental.
Meeting Room Wireless

An 802.11 a/b/g/n wireless network is being provided liberally throughout the venue.  802.11n is available on the 5Ghz frequencies. 

To use the meeting room wireless network, associate with the beaconed SSID of "ietf" for 802.11a/b/g/n and "ietf-a" for 802.11a/n.  IPv4 addressing is provided via DHCP.  IPv6 clients should use Dynamic Auto-configuration, and may use DHCPv6 to retrieve name server information. 

For those interested in more link-layer security, WPA SSIDs with 802.1X is available.  The SSIDs are "ietf.1x" and "ietf-a.1x". Do not use WPA-PSK as that will not work.  Also, using TLS as an eap method is not advisable, please prefer TTLS or PEAP.

To use 802.1X:
 1. Associate to SSID: ietf.1x OR ietf-a.1x
 3. Do Not Verify Server Cert and we won't verify yours :)
 4. Username (case sensitive): ietf
 5. Password (case sensitive): ietf

If you have an eduroam account, we support authenticating via eduroam.  Simply select the "eduroam" SSID.  Use your eduroam credentials.

For a pure-IPv6 environment, use the ietf-v6ONLY ssid.

The proper operation of the wireless network requires the assistance of all users.  One of the most significant issues with wireless performance in past IETF meetings has been wireless clients automatically, or accidentally, initiating "ad-hoc" networks that act as the official IETF wireless network, causing other users to associate with false IETF wireless networks.  Therefore, please disable your client's ability to create an ad-hoc network and as well as the ability to automatically join an ad-hoc network. 
Public spaces like the lobby and the bar that are covered by the hotel's wireless infrastructure require using the SSID "InterContinental". Their access points are on the IETF IP network, but won't be broadcasting our SSIDs.

Intercontinental Guest Room Access

The IETF Network is being extended to the guest rooms in the Intercontinental.  Guest room network access is available via wired and wireless (SSID "InterContinental").  Both IPv4 and IPv6 are deployed. 

Note that while we are using the IETF meeting network for Internet connectivity, we are using the Hotel's wireless infrastructure for the delivery to the guest rooms and lobby, so there are limits to the improvements we can effect.  We recommend using the wired connection whenever possible in your guest room.

Pullman Guest Room Access

In preparation for the IETF meeting, the Pullman Hotel has set up a special wireless SSID ("event") for attendees in the IETF block, credentials for which are being handed out to guests in the block upon check-in.  Unfortunately, early arriving IETF attendees found its performance has ranged from passable to completely unusable. By comparison, reports were that the wired network has been performing well.

The wired network and the Pullman's normal wireless net (SSIDs "m3connect" and "pullman") use device-specific credentials, separate from the shared credential for the "event" network.  If you need one of these, they are available to IETF block guests for free by asking the hotel's front desk.

Hence, if you are staying at the Pullman Hotel, you may wish to prepare to use the wired network in your hotel room.  Specifically, you may wish to bring with you an access point and/or a long ethernet cable with an RJ45 coupler.  Note that the ethernet cables provided by the Pullman (in at least some rooms) are both quite short and non-standard (pins 1 and 2 are swapped with 4 and 5), so neither straight cables nor standard crossover cables will work on their own. Accordingly, if bringing a long network cable, it may also be wise to bring an RJ45 coupler, using the provided cable to normalize pins and your cable to add length.

As a reminder, the IETF Network team deploys a network for the meeting space and endeavors to augment the guest room and public space Internet in the headquarters hotel.  Overflow hotels such as the Pullman are un-augmented, using the hotel's normal network infrastructure.

There is a printer in the Terminal Room and is available to all IETF users. The printer is an HP Officejet Pro 8600 Plus and is accessible via LPD, Bonjour, and standard TCP/IP on port 9100.  The hostname for it is term-printer.meeting.ietf.org.  It is possible to print from email.  For the email address, see the physical label on the printer.

Drivers can be found on the NOC wiki at https://tickets.meeting.ietf.org/wiki/IETF87network

=== Instructions for Mac OS X using Bonjour auto-setup (DNS-Based Service Discovery) ===
 1. Open System Preferences -> Print & Fax -> "+" below printer list
