But, Internet access does not work this time either. The problem I see is that .SE unfortunately did trust Stockholm Waterfront when they claimed that they could provide Internet access to the participants. That was, of course, not true. At Stockholm Waterfront just like any other conference facility, one must bring Internet access if one want it.
Just look at this. This is, to me, much worse than if the access is blocked (commands I send as a client in bold):
$ telnet mail.frobbit.se 25 Trying 220.127.116.11... Connected to mail.frobbit.se. Escape character is '^]'. 220 npas.netpoint.com Microsoft ESMTP MAIL Service, Version: 6.0.2600.3680 ready at Mon, 21 Nov 2011 10:08:33 +0100 quit 250-STARTTLS 250-AUTH GSSAPI NTLM LOGIN 250-AUTH=LOGIN 221 2.0.0 npas.netpoint.com Service closing transmission channel Connection closed by foreign host.
Note that not only is TCP/25 intercepted, the software that intercept the connection is not following the SMTP standard. That is sort of three fail out of two possible.
Another thing that surprises me of Stockholm Waterfront is that there is no electricity outlet by the seats. How hard could it have been to include when building the seats? And incremental cost, about zero.
So, for next year, please .SE, do talk with your friends and we can build a working network together.
