Full duplex is what happens when you remove CSMA/CD. I'm sure 99% of people out there have absolutily no need or desire for half duplex gige or 10gige, and I'm also sure 99% of people out there would be far better served by a larger MTU. Unfortunantly it's the other 1% at IEEE who write the spec. -- Richard A Steenbergen <ras(a)e-gerbil.net> http://www.e-gerbil.net/ras PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)

Sadmind/IIS hack from AS9800
by Erik Antelman 10 May '01

10 May '01

Our IIS/4 site was hacked early this morning by a Sadmind/IIS coming in from 211.96.252.251 Normally I would hesitate to admit publicly we practice unsafe systems management, but if the data helps others my ego will survive. for(;;); /* erik(a)cycletraders.com */

10 gige experience
by Mike Leber 10 May '01

10 May '01

Anybody out there have any experience with 10 gigabit ethernet? I'm looking for switches and routers that actually exist (heh, as opposed to the kind found in marketing literature). I've heard extreme is shipping 10 gige stuff. Any news when cisco or juniper will have something? +------------------- H U R R I C A N E - E L E C T R I C -------------------+ | Mike Leber Direct Internet Connections Voice 510 580 4100 | | Hurricane Electric Web Hosting Colocation Fax 510 580 4151 | | mleber(a)he.net http://www.he.net | +---------------------------------------------------------------------------+

Sadmind/IIS Worm Defaces IIS Websites via Solaris.
by Petri Stephen 10 May '01

10 May '01

A number of Websites were defaced by this worm. Check your patches. http://www.securitywatch.com/newsforward/default.asp?AID=7476 ....Sadmind/IIS, which automatically slithers into Solaris and Microsoft IIS machines, has claimed a site associated with British TV news gang ITN. As per its payload, the worm revamped the site's home page to curse hacker PoizonBOx and the American government.......... According to The Register, it is the first major reported hack that uses the worm.........is programmed to sneak into a Solaris 7 based system, using an old sadmind buffer overflow trick. Having root access, it automatically uses a folder traversal hole to take over IIS machines. Read the CERT advisory: http://www.cert.org/advisories/CA-2001-11.html.

Which is why I said 'default' MTU of 1500. I think it should have been a requirement of all 100TX devices to be able to accept FDDI sized packets, a requirement of GIGE to switch FDDI sized packets, etc.. Thats not what happened. The problem is that there is no graceful way to handle mixed MTU's at that layer. As a result, the default is to use legacy sized MTUs, which results in new equpment which can not handle the larger MTUs, resulting in the further delay of end-to-end jumbogram support. At some point, they need to draw a line and say that reception and switching of large >1500 byte packets must be supported and generation of such packets should be an option. This will finally make is possible for people to jumbogram enable their networks.

GB2312 is working on my system (not on your quoted text, but on the original as it came back to me posted to the list). I know nearly nothing about encoding, so I check with the translator and she confirmed that it was done in that. If that's not working for everyone, somebody give me a better idea of how to post it.

Mind you that this is from the tail-end of the haze-daze and the memory isn't quite clear. But, when I was writing ISO/OSI protocol stacks (a brain damn-aging activity in [and of] itself), ISO stood for "International Standards Organization". It was an acronym like GNU is an acronym, with multiple connotations and meaning. However, it was ALSO an acronym. This comes from around 83-84 when DOD decided to stop waiting and go with TCP/IP (a hack around layer 6 and 7 politics). > As for CCITT, well, what do you expect.
