Re: Network Monitoring System - Recommendations?
I use http://snmpstat.sf.net for bandwidth, links monityoring, router's cpu usage, etc etc; and http://cricket.sourceforge.net/ for additional parameters. First (developed in Moscow for few ISP) monitors abd adapted here for Enterprise (and shows everuything on the single scree, with traffic bars) 300 - 600 links without any problems (using approx 5% of servers cpu); second allows to monitor non standard parameters), have tickets, reports, alerts; second is very flexible (even to flexible). Btw, we implemented per-usert view (user can open his link and see traffic, tickets, usage reports etc for HIS link only) in snmpstat. (In reality, we use portal based on snmpstat, with few different tools integrated tiogether, such as Cisco Configuration Repository, ProBIND2 , inventory database, alert alias system with archive and so on). - Original Message - From: Jonathan Nichols [EMAIL PROTECTED] To: Andy Dills [EMAIL PROTECTED] Cc: Charlie Khanna - NextWeb [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Thursday, October 28, 2004 6:31 PM Subject: Re: Network Monitoring System - Recommendations? 3) Bandwidth reporting (or integration with an MRTG-type app) http://cricket.sourceforge.net/ You can also do this with Nagios now too.. with APAN. http://apan.sourceforge.net/ It's kind of cool. :D -Jonathan

Re: Finding information about metro private line service in downtown SF
Depends on the distance and what antennas you are using. If it's a short hop (which it sounds like it is) and you have very directional antennae, you can usually avoid most of the interference, especially if engineered correctly with frequency coordination (BANC) and checking of the frequencies with a spectrum analyzer before hand using the the antennas you plan to use (like stated earlier in this thread). But of course, stear away from the 2.4 Ghz band, look at 5 Ghz and beyond. -Mike On Thu, 28 Oct 2004 21:56:37 -0700 (PDT), Tom (UnitedLayer) [EMAIL PROTECTED] wrote: On Thu, 28 Oct 2004, Jeff Rosowski wrote: The Corning, FreeLink Optical Transport System looked pretty good as well if you have the money for it.

Re: Routers for CO OOB management network
I need to select a router to install in each of our CO's to bring together a network of T-1 between our colos. Look to Ebay or similar for 2500's with dual V.35. Either find them with DC supplies or buy DC supplies as spares. The DC version has only one inlet, but it is trivial to bridge an A/B supply with a diode bridge. We do so with our boxes. Depending on availability of DC supplies this could be very cost-effective. The 2600's DC supplies are an exact mechanical fit and have a slightly heftier power rating and may be easier to find. They sometimes appear on EBAY as either 2500 or as 2600 supplies at $20 or less each. If you get stuck, the supply manufacturer sold us 20 of them at $65 each a few years ago. You may have to be persistant, and promise to never tease ci$co about it. Remember to load all 2500s with 16 meg DRAM and 8 meg of flash (or more). If you have a lot of 4 meg flash sticks, use 2 in 1/2 your routers (and say: PARTITION FLASH 1 8 - rather than 2 4 4), and new 8 megs in the rest.The DRAM is about $10 on ebay, and the FLASH is maybe $20. Try hard for Intel flash chips (or Sharp clones that ID themselves as Intel) so you won't need to chase newer boot PLCCs if you get routers with old boot code than can't do AMD flash. Load them with unix compressed .Z images or see if you can find one of the kits that used to be around on the net to convert cisco run from FLASH images into more normal for cisco -mz gzipped types buried in a self extracting wrapper so your 25xx routers will behave like most other cisco routers. Find details in old C.D.S.C news archives. You can then load newer images onto a RUNNING router without the 2500 class B/S involving Flash-Load-Helper and remote disasters when flash is erased and tftp fails.

Much, much too late. The spammers/scammers have long since gotten their hands on all of it. Whether because it was overtly sold to them, or covertly sold under-the-table by employees looking to pick up extra cash, or acquired via other means, they have it. Moreover, they're managing to get their hands on changes to it (as incidental experiments with recently-modified data indicate). Here's one example: $299 gets you a pocketful of CDROMs stuffed with data: http://www.promotionsite.net/ There are many more of these, of course, offering various compilations of data at various prices and in various formats. At this point, no purpose is served by maintaining the pretense that this data is private, in any sense. It would be better for everyone to simply publish it in a simple format (e.g. one static web page per doamin or network) so that everyone is on a level playing field. (As to the comment about registrars locking up more and more data: evidence is growing that at least a couple of registrars ARE the spammers they're registering domains for. Makes sense: if you're going to burn through thousands of domains, you might as well sell them to yourself cheaply.) ---Rsk
