MPLS ICMP Extensions
by Leo Bicknell 18 Aug '03

18 Aug '03

I wanted to get some other opinions on some new features that have appeared in recent code from the popular vendors. It appears there is a new draft, a copy of which can be found at http://www.watersprings.org/links/mlr/id/draft-ietf-mpls-icmp-01.txt that allows MPLS enabled boxes to return some additonal information in a traceroute packet. That's all well and good, and I can see how that might be amazingly useful to someone running an MPLS network, however, it seems to expose data much further than the local network. Here's a random example from a traceroute I recently performed (on a Juniper): traceroute wcg.net [snip] 11 hrndva1wcx3-oc48.wcg.net (64.200.95.117) 91.935 ms 102.652 ms 92.960 ms MPLS Label=13198 CoS=0 TTL=1 S=1 12 hrndva1wcx2-oc48.wcg.net (64.200.95.77) 92.593 ms 92.785 ms 93.119 ms MPLS Label=12676 CoS=0 TTL=1 S=1 13 nycmny2wcx2-oc48.wcg.net (64.200.240.45) 93.273 ms 93.121 ms 93.067 ms MPLS Label=12632 CoS=0 TTL=1 S=1 14 nycmny2wcx3-oc48.wcg.net (64.200.87.78) 104.755 ms 91.949 ms 92.169 ms MPLS Label=12672 CoS=0 TTL=1 S=1 15 chcgil1wcx3-oc48.wcg.net (64.200.240.37) 92.021 ms 91.737 ms 91.684 ms MPLS Label=12592 CoS=0 TTL=1 S=1 16 chcgil1wcx3-pos5-0.wcg.net (64.200.210.114) 175.907 ms 278.144 ms 203.763 ms MPLS Label=12695 CoS=0 TTL=1 S=1 17 chcgil1wcx2-oc48.wcg.net (64.200.103.73) 93.286 ms 93.230 ms 93.593 ms MPLS Label=13506 CoS=0 TTL=1 S=1 18 stlsmo3wcf1-atm.wcg.net (64.200.210.158) 92.780 ms 92.344 ms 92.596 ms It appears both Cisco and Juniper support this new feature. The question I quickly asked both vendors is how do you turn this behavior off, so the traceroutes appear as they did before this feature was introduced. The answer, apparently, is you don't. You can either disable TTL processing on your MPLS tunnels (in effect disabling traceroute), or you can have it output all this extra information. The response I'm getting so far from each vendor is they believe this are the right two options to offer. Thus, my post here. I think there are more people out there who would like to not expose their MPLS labels, Class of Service info, or anything else this feature can provide (because, I don't know all of what it can display), but still allow traceroute to work normally. If I'm off in the deep end, please tell me so, if not, please tell your vendor rep you'd like the "icmp no mpls info" knob. -- Leo Bicknell - bicknell(a)ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request(a)tmbg.org, www.tmbg.org

Did Sean Gorman's maps show the cascading vulnerability in Ohio?
by Sean Donelan 18 Aug '03

18 Aug '03

So, the US Government wants to classify Sean Gorman's student project. The question is did Mr. Gorman's maps divulge the vulnerability in the East Coast power grid that resulted in the blackouts this week? Would it be better to know about these vulnerabilities, and do something about them; or is it better to keep them secret until they fail in a catastrophic way?

yipes! in 401
by alex＠yuriev.com 18 Aug '03

18 Aug '03

Hello, Have anyone taking IP from yipes at 401 North Broad in PHL seen any interesting "issues" with them over last two weeks? Please reply off the list. Oh, and if anyone from Yipes and Williams feels like explaining how they can stuff what it claims to be a gige on traceroutes into what behaves like an non-overloaded ATM OC3 (or hightly overloaded ATM OC-12) where Yipes is connecting to Williams, I would be all ears... Thanks, Alex

Windows update down again?
by variable＠ednet.co.uk 18 Aug '03

18 Aug '03

Hi all, I was just updating a couple of Windows machines and had been using Windows Update without any problems until about 5 mins ago (22:10 GMT) when I've started getting this: "Thank you for your interest in Windows Update Windows Update is the online extension of Windows that helps you get the most out of your computer. The latest version of Windows Update is available on computers that are running Microsoft Windows 98, Windows 98 Second Edition, Windows Millennium Edition, Windows 2000 (except Windows 2000 Datacenter Server), Windows XP, and the Windows Server 2003 family." URL is http://v4.windowsupdate.microsoft.com/default.asp which redirects to http://v4.windowsupdate.microsoft.com/en/thanks.asp. Also happens for http://windowsupdate.microsoft.com/. This is from multiple machines running Windows 2000 (Pro and Server) and Windows 2003 server. Anyone else seeing this yet? Does anyone know of an alternative URL for Windows Update in the meantime? Rich

XP pro has been shipping with a F/W for a year now, I'd say? no suits yet. In fact, I read some review (CNET, etc) that said the XP F/W in conjunction with Zone Labs ZoneAlarm was very effective, given the test parameters. I have ran mine since day 1, with both DSL and dial-up. All systems go. Jim
