Re: Microsoft distributes free CDs in Japan to patch Windows

That's going to hit your bottom line. >> Ever heard of Windows 98? >> How about Windows 98 SE (Second Edition)? >Windows 98SE was only available to OEMs and wasn't on shelves in stores. >As Valdis also notes, it's an entirely different situation. Entirely!?!?!? Seems to me that Microsoft was once able to bundle up various OS updates and release an up-to-date version of their current OS. So, why can't they do the same thing today? Failing that, why can't they bundle up just the updates onto a CD that is released every few months and shipped out to all of their regular customers along with permission to copy and redistribute. That way more OEM's would ship out fully updated machines. --Michael Dillon

Networks dropping all ICMP
by Andrew Staples 09 Sep '03

09 Sep '03

A certain network last week decided to drop *all* icmp traffic across its network for an indefinate period of time. They did this to reduce the effects of Nachi. Apparently (their) Redback DSL concentrators cannot filter only 92 byte packets, it's all or none. Does anyone else care to respond publicly or privately with data about other networks filtering all icmp traffic, not just malformed icmp? I'd like to compile a list for troubleshooting, as these decisions are breaking things for some customers. Andrew Staples perl -e "print(pack('H54','616e647265772e737461706c6573406e776e6574636f6d2e636f6d')) ;" "I don't think I'm alone when I say I'd like to see more and more planets fall under the ruthless domination of our solar system."

It's 12.2 code. show ip int e0 shows that CEF is enabled on the interface. Supposedly 12.2's CEF also handles policy routing (which is not being used on this router). > -----Original Message----- > From: Jason Frisvold [mailto:friz@corp.ptd.net] > Sent: Tuesday, September 09, 2003 10:24 AM > To: Austad, Jay > Cc: nanog(a)merit.edu > Subject: Re: cef/process switching problem > > > Not sure on the MC3810 (never used one), but I know that many of the > other Cisco routers didn't do CEF on ethernet until later revisions of > code...

cef/process switching problem
by Austad, Jay 09 Sep '03

09 Sep '03

I've got a cisco MC3810 with a bunch of DSL customers on it. CEF is enabled, but when I do a show int stat, I see that almost 100% of the outbound packets on the ethernet interface are process switched, and not being matched in the route cache. The Input looks just fine, and the other interfaces are borderline (usually 50% hit rate on the cache or a little less). CPU is sitting pretty high on this box during the day, and I have strong suspicions that this is why. :) I can't seem to find any info on why this would be happening or how to figure out what's going on. Anyone have any suggestions? -jay

Cisco ONS 15454 Password Recovery
by Matthew Crocker 08 Sep '03

08 Sep '03

Dear List, I know this isn't the correct forum and for that I apologize. I have been searching Ciscos website for the past 5 hours with no luck. I need to know how I can gain access to a Cisco ONS 15454 with TCC+ running 2.2.1 software rev. If anyone knows how to accomplish this please e-mail me off list. I have physical access to the unit, I can access it via Telnet, TL1 or CTC (web). The Node isn't in service now so I can power cycle it if needed. I need to get this into service tomorrow and I have exhausted all of my ideas on where to look for the information. Ideally I would like to reset the CISCO15 password to the default ('') without deleting the database. Thanks -Matt
