IETF 97 Network Information – Seoul, South Korea

Terminal Room

The Terminal Room is located in Studio 1 on the 5th floor. The Terminal Room is open 24 hours each day beginning Sunday, 13 November, 2016 at 16:00 and ending on Friday, 18 November, 2016 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 240v power ports. There is also an HP Officejet Pro 8610 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

NOC and Ticketing

There are several ways to communicate with the NOC staff.

  • Submit a new trouble ticket via the 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 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.
  • 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.

External Connectivity

The IETF 97 network connects to the Internet via two 1Gb/s uplinks; one graciously donated from NTT and one purchased from SK Telecom as backup. The IETF uses 2001:67c:370::/48 for IPv6 and 31.133.128.0/18 and 31.130.224.0/20 for (legacy) IPv4. We are supplying bandwidth for the conference space, as well as wireless connections in the guest rooms via the "Conrad_Seoul" SSID.

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-legacy 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
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

Guest Room and Public Space Access

The IETF Network is being extended to the guest rooms and public spaces throughout the Conrad. In the guest rooms, the IETF network is available via the "Conrad_Seoul" SSID. This network is 2.4GHz and 5GHz and delivered via the hotel's Mac Mini in each room. In the public space, the usual "ietf-hotel" SSID is available, using the hotel's wireless infrastructure to deliver the IETF network.

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 SSID "Conrad_Seoul" or the "ietf-hotel" SSID in the public space, please contact us in the Terminal Room (Studio 1) 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

Geolocation

There is a geolocation feed published here: https://noc.ietf.org/geo/google.csv Geolocation service for temporary networks is often hit or miss. Suggestions/assistance is welcomed. You can also try searching via www.google.com/ncr (no country re-direct).

Thanks

The terminal room and IETF network are made possible by the generous contributions by a number of companies and by the tireless efforts of our volunteer team. If you see any of these people in the halls, please be sure to thank them for all their work!
