[as112-ops] Reminder: DITL 2016

[William F Sotomayor]

All,

Two months ago we announced that we will be holding another DITL collection.
As in previous years we are looking to solicit captures primarily from the
root operators, but this need not be restricted to just them:  Any TLD
operator including AS112 operators are encouraged to participate.  Also,
those who agreed to contribute DITL data as part of their membership
agreements are warmly expected.

Testing was done during mid-March and went smoothly.

--> The actual event itself will be:  April 5 to 7 inclusive, 2016. <--

(This time slot was chosen in particular because of relocation pressures
upon DNS-OARC.)

Your settings.sh file should look like this:

START_T='2016-04-05 11:00:00'
STOP_T='2016-04-07 13:00:00'

(All times UTC)

As usual, remember to:

- Refresh your memories about what DITL is about:

         https://www.dns-oarc.net/oarc/data/ditl

- Ensure your patched NTP/clock sync software is functioning on your
   participating servers;

- To have a look at the latest 'ditl-' capture software suite located
   here:

         https://dnscap.dns-oarc.net/

   For those who like to live on the edge, there is also a Github version
   of dnscap at:

         https://github.com/verisign/dnscap

- And familiarise yourselves with the upload process which hasn't changed
   over the course of the years:

         https://www.dns-oarc.net/ditl/2011/

Note that if you do chose to participate, it's a good idea to join the
DITL mailing list where questions and discussions for the event are best
held:

         https://lists.dns-oarc.net/mailman/listinfo/ditl

Those of you who would like to do test uploads one-on-one with OARC,
please contact admin at dns-oarc.net.

(Members may also access the 'ditl' conference room on the DNS-OARC jabber 
server during the event.)

For those of you who have the HPN-SSH version of OpenSSH, you may elect to
have your SSH clients connect using that feature.  If you wish to
test this feature the capture servers are enabled for it.  The servers
will try to optimise the connection to have your transfers sped-up,
subject to network, system and stack tuning.  For more information on how
to do this, please refer to ESNet's Host Tuning web page for your
particular operating system:

          https://fasterdata.es.net/host-tuning/

For details on HPN-SSH and patches, see:

          http://www.psc.edu/index.php/hpn-ssh

An example invocation used @ DNS-OARC is:

          '/usr/local/bin/ssh -caes128'

When passed to rsync.  Those who do not wish to use HPN-SSH clients will
remain unaffected and uploads will proceed as normal.

Finally, at the participants' discretion, xz-compressed files are accepted 
in place of gzip-compressed files for those pressed on space and network 
latency.  The next release of the ditl toolsuite will support tweaking the 
settings.sh file with one option intead of making manual changes in a few.

Thank you,

William
