IETF 80 Network Information - Prague, Czech Republic

Terminal Room

The Terminal Room is located in Chez Louis on the Mezanine Level of the Prague Hilton and is open 24 hours a day beginning at 4pm on Sunday, March 27 and ending at 4pm on Friday, April 1st. A help desk is being provided and will be manned from 8:00 AM to 8:00 PM every day. The room itself consists of approximately 80 seats providing wired 10/100/1000 Ethernet access and 220v Schuko (round two pin circular inset with ground pin) power ports. There is also a duplex color 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. 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.

There are also two SIP phones available for use. These terminate to a server in the US, so only US and Canadian numbers are accessible. For other country codes aside from +1, you will need to use a US or Canadian calling card.

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 20:00
Wednesday 8:00 to 20:00
Thursday 8:00 to 20:00
Friday 8:00 to 16:00

NOC and Ticketing

There are several ways to communicate with the NOC staff.

  1. Submit a new trouble ticket via the trac web interface. 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) to 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 on the Mezzanine level in the Chez Louis Salon room to the left of the Café Bistro.
  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

The IETF 80 network connects to the Internet via two gigabit Ethernet links, provided by NIC.CZ and Dial Telecom. The entire event is addressed out of the 130.129.0.0/16 block for IPv4 and 2001:df8::/32 for IPv6. IPv6 is native and is supported by both providers. We are supplying bandwidth for the meeting spaces, hotel wireless and in-room wired connections. The in-room wired access has gigabit to each port, but does not support IPv6 due to lack of support by the guest room aggregation equipment.

Meeting Room Wireless

An 802.11 a/b/g/n wireless network is being provided liberally throughout the venue hotel. 802.11n is only available on the 5Ghz frequencies. Guestroom wireless access is being provided by the hotel's equipment using the "hilton" SSID and may have different functionality than the IETF gear. Please see the section on Guest Room Access.

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 adviseable, please prefer TTLS.

To use 802.1X:

  1. Associate to SSID: ietf.1x OR ietf-a.1x
  2. Use PEAP/MSCHAPv2
  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.

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.

Experimental Networks

There are two experimental SSIDs. "ietf-v6ONLY" is there to demonstrate the current state of an IPv6 only Internet. Do not expect any services to be available via IPv4 on this SSID. There is also an SSID called "ietf-nat64" which is a demonstration of nat64 services. This network has a specific DNS server for use with the demonstration located at node 2001:df8:0:7::1.

SSID Access Credentials Purpose
ietf-v6ONLY None A IPv6-only network for investigating IPv6 in the absence of IPv4
ietf-nat64 None A demonstration of NAT64
eduroam Your eduroam credentials An instance of the eduroam project. See eduroam website

Guest Room Access

The IETF Network is being extended to the guest rooms on both wired and wireless. The in-room wired access has gigabit to each port, but it does not support IPv6 due to lack of support by the guest room aggregation equipment. Guest room wireless is available through the "hilton" SSID.

Printing

There is a printer in the Terminal Room and is available to all IETF users. The printer is an HP3525dn which is Postscript capable and has the duplex option installed. The printer is accessible via LPD, Bonjour, standard TCP/IP on port 9100. The hostname for it is terminalroom-printer.meeting.ietf.org.

Name Model Capabilities IPv4 Address IPv6 Address Notes Drivers
terminalroom-printer.meeting.ietf.org HP CP3525dn Color Laser w/Duplexer 130.129.48.16 2001:df8:0:48:7aac:c0ff:fe90:b5c6 Bonjour name: IETF Terminal Room (HP CP3525) HP Support

Instructions for Mac OS X using Bonjour auto-setup (DNS-Based Service Discovery)

  1. Open System Preferences -> Print & Fax -> "+" below printer list
  2. Choose "Default" in the top-menu.
  3. You should see the printers discovered by Bonjour. Pick the right one.
  4. Enjoy hassle-free printing.

Instructions for Mac OS X using manual configuration

  1. Open System Preferences -> Print & Fax -> "+" below printer list
  2. Select the "IP" icon at the top of window
  3. Select the "HP Jetdirect - Socket" from the dropdown
  4. Enter "terminalroom-printer.meeting.ietf.org" in the Address field. Leave the Queue field blank.
  5. Print Using should autopopulate with "HP Color LaserJet CP3525" driver. If not, select it.
  6. Click Add

Instructions for Windows using Windows printig system (in Vista layout)

  1. If you haven't printed on selected printer before, download and install the driver (do not use any of "wizzard" or "automated" packages).
  2. Start -> Settings -> Printers & Faxes -> Add Printer -> Add Networked printer (and click Next) - some waiting time 3a. If you are hooked to wired network in terminal room, you are able to add all printers and you are done 3b. If you aren't hooked to wired network in terminal room, click STOP in searching printers
  3. Click "desired printer isn't in the list"
  4. "Add printer using TCP/IP address ..."
  5. Select "Type" as "TCP/IP device" and IP adrres of desired printer
  6. Select printer driver (you may need to choose it from package you installed in step 1) - Do NOT click "Windows Update"
  7. Click next (two or three times - depends on your windows version and drivers installed) and wait till the printer is added

Instructions for Windows using HP printing framework

  1. Download HP Universal Print Driver for Windows PostScript from HP Support
  2. Select "Dynamic instalation" and wait till all drivers are copied (takes about 5-10 minutes)
  3. Add printers by using their IP addresses in "control pannel" appearing when select Start -> Settings -> Printers & faxes -> "HP Universal Printing PS" -> Properties
