Small Tests (already done)

• FTP
• Fccn (PT) Cesga (ES)
• using ftp//ftpuipv6/ftp.ipv6.cesga.es
• Upload and Download
• Mput/Mget (anybody still using command line?)
• 100Mb Random Generated File
• dd bs1 countsize if/dev/urandom of./testfile

RTTs

• Setup of one Loopback Address to serve as a test
  beacon for other NRENs
• FCCN 20016901
• DNS integrated
• Objective
• To measure Roundtrip Times between all native
  members
• easily
• anytime

ServicesTesting Methodology

• Distributed testing isnt easy to coordinate
• Need to decide who wants to participate
• Need to decide if participation is total or
  parcial (some people may not want to take part in
  all tests)
• Gather as much data as possible today
• Discuss each test, trying to improve them
• Philosophy is each participant does both the
  server and the client side

7
Services

• DNS
• FTP
• WEB
• NTP
• EMAIL
• VIDEOCONFERENCING
• ... ??? (suggestions please)

8
DNS

• Everybody
• Setups a Zone on a DNS Server
• With Zone Transfer Permission
• Transfers other NRENs Zones, using DIG _at_server
  zone axfr
• Needed Data
• DNS Server Address/Name
• Zone to transfer

9
FTP

• Rediris ftp.ipv6.cesga.es (ftpu/ipv6)
• Fccn ftp6.ip6.fccn.pt (anonymous)
• More??? Each new NREN needs to
• broadcast authentication data for its own
  server
• broadcast which directory has writeon
• generate own 100Mb Testfile
• Checksum mechanism?
• The idea is
• get all the testfiles from each testfile source
• uploads his own testfile everywhere

10
WEB

• Everybody
• Setup of an AAAA record (www) on a zone
• Insertion of a Keyword on the index page
• Broadcast of the address
• Access all participants servers and retrieve
  all keywords
• Alternative
• no keywords, people just give out an existent
  http// URL on their network

11
NTP

• Everybody
• Setups their server
• Synchronizes it to some dantes server? (lower
  stratum)
• Broadcasts the address
• Uses a client to run ntpdate and ntptrace (ipv6
  versions)

12
EMAIL

• Everybody
• setups MX record on a zone pointing to a name
  with only a AAAA record
• setups a mailbox called geant-test on that
  server
• broadcasts its own domain
• sends a message to everyones address,
  containing text and an attached image.
• Suggestions sendmail/postfix

13
VIDEOCONFERENCING

• Maximum Setup 2-person call
• Linux Gnomemeeting
• http//www.gnomemeeting.org
• http//www.join.uni-muenster.de
• Windows Netmeeting
• http//www.microsoft.com
• On IPv6 (still unavailable!)
• MCU
• Directory Services / Gatekeeper

14
Traffic Generation

• MGEN6 (over Unix/Linux)
• http//matrix.it.uc3m.es/long/software/mgen6
• Easy and Quick Way to Generate Traffic
• Boost your traffic graphs ?
• Generator/Analyzer Hardware
• FCCN has a STM-1 capable SPIRENT box
• GARR has something similar? (mentioned in 3rd
  meeting)
• Anybody else...?
