Maybe it'll be done in two weeks, maybe not. But whenever it's done, I'm sure it'll be great. BTW, I'm curious why some people don't seem to like the idea. At the speed of modern systems, I suspect that loading uncompressed off flopy isn't much faster (if at all) than loading compressed off floppy and decompressing. In fact it may be slower. I'd test it right now but my arms aren't 4 miles long, which they'd have to be to reach the closest floppy drive on one of my NetBSDs... Heh. I can just see it. gzip becomes a kernel function. Although that's not really a joke- compressing filesystems aren't far off that mark... /a

I'd like to point out that 1 ns of latency equivalent to 1 ft of wire (more-less), so 1 ms of latency is 190 miles of wire. It is not a serious delay, when compared with typical thousand-mile backbone links. (1 ms is a _lot_ of time to route a packet). --vadim

I beieve my troubles with cisco flash were due to the relatively frequent updates (once a week or so) and somewhat high ambient temperatures (there wasn't adequate air flow). Solid-state nonvolatile memories age rather eapidly in those conditions. --vadim

The environment wasn't especially dusty, but it wasn't a clean room. I'd hesitate to use any floppy-booted device intended for use out of arm's reach. -- Robert

At one time I used them in firewalls, and every now and then, tripwire would report random changed bits on the disk, and then the next time I ran tripwire, the problem would just go away. Now I use low end SCSI drives for these kind of applications cause I prefer to have all my data parity checked. Rob

GigaRouter Latency?
by Deepak Jain 20 Oct '96

20 Oct '96

Now I know a lot of people are going to jump on me for raising the latency question here, and I don't want to inflate its importance at all. Latency in a router is only somewhat important for most network applications but on some applications it has a very serious effect. If anyone would like to flame me, please do it in private email and I am sure I will find the time to get back to you :). How does the latency through a Gigarouter compare to the latency of say a NetBSD or FreeBSD box with (say) FDDI interfaces. [Ignoring the fact that most BSD boxes are running on a single PCI bus]. Basically I am curious how much advantage/disadvantage one gets by going from a Cisco to a Gigarouter solution based on issues like latency. I am sure the difference we are talking about is very slight and <2ms total, I just want to get an idea and I don't trust most of the technical sales personnel I have talked to to get a straight answer. I am very familiar with the latency of BSD (typical) boxes and those of Cisco Routers. Thanks, -Deepak.

One of the reasons that cisco has earned its place as Number One is that, to my knowledge, cisco has never terminally screwed a client. No other contender can make that claim with me. I've been screwed by all of them, except cisco. They don't always give me what I want when I want it, but they don't do fundamentally bad things like walking away from the ISP market as Proteon did or wiping out their upper management team as Wellfleet did from time to time. cisco is no longer easy to work with in many respects, there is so much management for a large company. But in the early days, cisco was one of the first companies to turn their customer support inside out on the Net. You could (still can) talk to anyone in the company about almost anything. Not as easy as it was, but it can happen. But you can't get one engineer to hack something into the router code for you on just his say-so anymore. But once you could. I dunno maybe you still can, but I think you have to have megabucks behind you to do it. --Kent

Re: Cyberpromo.com spam snuffed?

cyberpromo may have had their own site disconnected -- but they're still practicing their arrogant ways. They surreptiously used our system on Thursday to spam compuserve and aol, as well as prodigy. The plethora of bad email addresses brought our server to its knees for some time. We're planning on seeking damages and taking them to court if they don't compensate us for the trouble that they caused. I believe that we're also going to name the original client of cyberpromo as well -- a hardware house in california, as well as carnival cruises -- just to make the pain felt and spread to the business community the news of what's going on. Not sure on that one. If anyone else here was a victim of cyber, let me know. > From owner-nanog(a)merit.edu Fri Oct 18 20:26:56 1996 > Date: Fri, 18 Oct 1996 20:02:17 -0400 (EDT) > From: "Todd R.
