Subject: [100all] IETF 100 Network Information

From: Jim Martin <[email-masked]>
Date: Fri, 10 Nov 2017 13:51:31 +0800

Gentlepeople,
	Welcome to Singapore! Below you will find the usual Network Information documentation. As always, it’s a render of the wiki page the NOC keeps at https://tickets.meeting.ietf.org/wiki/IETF100network <https://tickets.meeting.ietf.org/wiki/IETF100network> … please reference that as it’s MUCH more readable.

	This meeting we’re trying very hard to help NAT64 mature enough that it could potentially be viable as the primary way people access the Internet. To that end, Jen Linkova ([email-masked] <mailto:[email-masked]>) and Randy Bush ([email-masked] <mailto:[email-masked]>) have put forth the following request:

——
The IPv6-only SSID 'ietf-nat64' has been available at IETF meetings for
years; but unfortunately the number of devices using that network is
usually far lower than on the dual-stack one.  It would be highly
desirable to see more people using it (or to know why they can not) as
we should eat our own dogfood.  If you have not been using the
'ietf-nat64' SSID please try to use it instead of the dual-stack 'ietf'
one.  You may want to modify your network preferences to ensure that
'ietf-nat64' SSID is preferred over other SSIDs (MacOS instructions can be
found at https://support.apple.com/kb/PH25285?locale=en_US <https://support.apple.com/kb/PH25285?locale=en_US>

MS Windows instructions are available at
https://answers.microsoft.com/en-us/windows/forum/windows_10-networking/how-do-i-change-wireless-network-priority-in/17b30700-d710-44d9-abbf-74efda22b039?auth=1 <https://answers.microsoft.com/en-us/windows/forum/windows_10-networking/how-do-i-change-wireless-network-priority-in/17b30700-d710-44d9-abbf-74efda22b039?auth=1>)

If for some reason you'd prefer to use an unencrypted wireless SSID, the
'ietf-nat64-unencrypted' is an open SSID that drops you on the same L3
network segment as 'ietf-net64'.

Unfortunately it is possible that some applications may have problems
using the NAT64 network.  If you experience issues while using the
'ietf-nat64' SSID (or 'ietf-nat64-unencrypted') please follow these
instructions:

 - connect to the dual-stack 'ietf' (or 'ietf-legacy100') SSID. If the
   problem disappears open a ticket with NOC, either by using the
   ticketing system https://tickets.meeting.ietf.org/ <https://tickets.meeting.ietf.org/> or by sending
   email to [email-masked] <mailto:[email-masked]>. It would really help if you could
   provide the following information:
   . Operating System and the application you are using, with version
     numbers
   . The symptoms you observed;
   . Any other information you believe is relevant; (if you can provide
     a tcpdump capture it would be really appreciated).

There will be a survey sent at the end of the IETF100 week so you can
share your experience/suggestions/concerns/complains/etc.

Everyone who reported the broken application or filled out the survey
will be entered in a drawing: USD100 will be anonymously donated to a
charity of the winner's choice! (Yes, if you did both you enter twice).
—

	Again, welcome to Singapore, and have a great week!

	- Jim and the NOC Team

= IETF 100 Network Information – Singapore, Singapore =

== Terminal Room ==

The Terminal Room is located in Ord and Blundell which is adjacent to the South Atrium on the 4th Level of the Raffles City Convention Center. The Terminal Room is open 24 hours each day beginning Sunday, November 12th, 2017 at 16:00 and ending on Friday, 27 November, 2017 at 15:00. A help desk is provided and the hours are listed below.  The room itself consists of approximately 50 seats, providing some wired access and 220v power ports with type G (UK) connections. There is also an HP Officejet Pro 8710 printer available.

Please note that this terminal room has no terminals, PCs, or other user-accessible machines. It is simply a place to get power, wired and wifi Internet access, help desk support, print documents, and/or work quietly.

When using the Ethernet connections in the Terminal Room, IPv4 addressing is provided via DHCP. Please use Stateless Auto-configuration for IPv6 (SLAAC). A DHCPv6 server or RDNSS 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 staffed the following hours: 

|| Sunday || 16:00 to 19:00 ||
|| Monday ||  8:00 to 20:00 ||
|| Tuesday ||  8:00 to 19:00 ||
|| 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. 
 * Submit a new trouble ticket via the [https://tickets.meeting.ietf.org/newticket "trac web"] interface. Filling in the following fields: "My MAC Address", "My Current Location", and "My OS" expedite ticket processing. If you have an existing account on https://tools.ietf.org you can use your established credentials (email address and tools password) to [https://tickets.meeting.ietf.org/login "log in"].
 * Send an email to '''`tickets @ meeting.ietf.org`''' with as much detail regarding your issue and configuration as possible. 
 * If you're on site and need direct network assistance (i.e - you have no network) please go to the Help Desk, which is located in the Terminal Room.

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

The Secretariat also maintains a ticket system for the reporting of meeting issues. Please send 
mail to: '''`mtd @ietf.org`''' to report a problem. The Secretariat is responsible for addressing issues with:

    * A/V in meeting rooms
    * Beverage and food
    * Jabber
    * Projectors
    * Temperature fluctuation

== External Connectivity ==
 
The IETF 100 network connects to the Internet via multiple 1Gb/s uplinks donated by Starhub, NTT Communications, !ViewQuest, and Moratelindo. The IETF uses 2001:67c:370::/48 and 2001:67c:1230::/46 for IPv6 and 31.133.128.0/18 and 31.130.224.0/20 for IPv4. We are supplying bandwidth for the conference space, as well as wireless connections in the guest rooms of the Swissotel and both wired and wireless in the Fairmont hotel. 
       
== Meeting Room Wireless == 

An 802.11 a/g/n/ac wireless network is provided throughout the venue on both the 2.4 and 5 GHz bands, in conjunction with IPv4 and IPv6 addressing options. 

The main “ietf” wireless network is encrypted; make sure you enter ietf for both the username and password.

Here’s a quick summary of the network layout:

|| SSID || Description || Encrypted || Frequencies || IP Versions ||
|| ietf  || Our default network || yes || 5Ghz only || v4 and v6 || 
|| ietf-legacy100 || For legacy and unencrypted use || no || 2.4 and 5Ghz || v4 and v6 ||
|| ietf-2.4ONLY || An encrypted network for 2.4Ghz users || yes || 2.4Ghz only || v4 and v6 ||
|| ietf-v6ONLY || For users wanting pure IPv6 || yes || 5Ghz only || v6 only ||
|| ietf-nat64 || IPv6 stack with NAT64 to access IPv4 resources || yes || 5Ghz only || v6 with NAT64 & DNS64 ||
|| ietf-nat64-unencrypted || IPv6 stack with NAT64 to access IPv4 resources || no || 2.4  and 5Ghz || v6 with NAT64 & DNS64 ||
|| eduroam || educational users || yes || 2.4 and 5Ghz || v4 and v6 ||

All networks marked as encrypted will offer layer 2 security. This is done using WPA2 enterprise with 802.1X (PEAP or TTLS) authentication and AES encryption. As usual, we are all using the same credentials (user “ietf”, password “ietf”), yet each user will get unique session encryption keys. Stefan Winter has kindly provided signed profiles that will supply the appropriate SSL certs: https://802.1x-config.org/?idp=137&profile=101

Our wireless LAN infrastructure implements the following two BCP38-like filtering.
* Packets from manually configured IPv4 addresses that are not assigned by DHCP are dropped. DHCP packets are snooped by our wireless LAN controllers to perform this filtering.
* Packets from IPv4 and IPv6 addresses that cannot be resolved via ARP/NS are filtered out. Proxy ARP/ND is performed by our wireless LAN controllers for this filtering.

== Experiments ==

Experiments on the IETF network need to be approved by the IETF Chair.  For IETF 100, the following Experiment has been approved and has been implemented:
    * DNS-over-TCP (DPRIVE) 

== Guest Room and Public Space Access ==

The IETF Network is being extended to the guest rooms and public spaces throughout the Swissotel and the Fairmont.  This is being delivered via the hotel's wireless infrastructure as an additional SSID, "ietf-hotel".  In the Fairmont, the wired ethernet in the guest rooms will connect you to the IETF network. There is no wired ethernet in the Swissotel guest rooms.

**Note** If you have performance issues with this network, please let us know. Please note though, that while we are using the IETF meeting network for Internet connectivity, we are using the hotel's infrastructure for delivery to the guest rooms and public space, so there are limits to the improvements we can effect.  

== Support ==

If you have trouble using the guest room and public space SSID "ietf-hotel", please contact us in the Terminal Room (Ord and Blundell rooms) or via '''`tickets @ meeting.ietf.org`'''  and we’ll be glad to help!

=== A Note For Windows Users ===

Connecting to the ietf SSID on Windows 7 requires a few extra, non-intuitive steps. If you're struggling to get connected to an encrypted SSID on your Windows laptop, please come by the Help Desk. Alternatively, you can try yourself; Instructions are here >> https://tickets.meeting.ietf.org/attachment/wiki/WindowsInformation/IETF%20Wifi%20Instructions%20Windows.pdf

== Printing ==

There is a printer in the Terminal Room and is available to all IETF users. The printer is an HP !OfficeJet Pro 8710 and is accessible via LPD, Bonjour, standard TCP/IP on port 9100.  The hostname for it is term-printer.meeting.ietf.org.  This printer is compatible with the !OfficeJet Pro 8620 we've used in previous meetings, so if you were able to use the printers previously, this one should "just work".

|| Name || Model || Capabilities || IPv4 Address|| IPv6 Address || Notes || Drivers ||
||term-printer.meeting.ietf.org || HP Officejet Pro 8710 || Inkjet w/Duplexer || 31.133.160.18 || 2001:67c:370:160::18 || Bonjour name: // term-printer // || [https://support.hp.com/us-en/product/HP-Officejet-Pro-8610-e-All-in-One-Printer-series/5367611/drivers Printer Drivers] ||
