free network monitoring/management tools
by Joshua Smith 13 Nov '02

13 Nov '02

hello to all, i would appreciate your your knowledge and experiences regarding freely available tools for network monitoring and management (all cisco now, some other stuff later). i would prefer free tools as i have no budget :) i am looking for the following (it will be running on either freebsd or redhat): AAA - i have been trying to find a tacacs+ daemon/program that doesn't require me to also learn *sql to set up the backend database (if this is the only choice, then i can learn it) config monitoring/management - rancid or rtrmon are the two that i have found. any preferences on one over the other in terms of ease of use, ability to modify/improve, efficiency, etc? network/syslog monitoring - some of the likely candidates i have found are nagios or netsaint, jffnms, nmis, opennms, or maybe snip (formerly nocol) - i need something that is fairly easy to setup and use, and it doesn't have to do a whole lot (just some basic notifications for now). decent documentation is also necessary, and a pretty map would be nice for my noc, but this isn't a prereq. my scripting/programming skills are rudimentary, so it would be ideal if it was at least partially plug-and-play (i know i know, sorry). i would appreciate any input (i am still reading through the archives for useful tidbits), and i, of course, will gladly summarize for the list. thanks in advance joshua "Walk with me through the Universe, And along the way see how all of us are Connected.

There was no indication about when CERT itself was going to issue an advisory, but clearly someone said something a day earlier than had been expected. --Steve Bellovin, http://www.research.att.com/~smb (me) http://www.wilyhacker.com ("Firewalls" book)

Haven't seen mention of this yet today and DNS affects most everyone in some way. The advisory was released a day early according to FreeBSD security officer. http://bvlive01.iss.net/issEn/delivery/xforce/alertdetail.jsp?oid=21469 & http://marc.theaimsgroup.com/?l=freebsd-security&m=103712312402461&w=2 G

Equinix -- Good High Bandwidth Providers -- Verio??
by Flint Barber 12 Nov '02

12 Nov '02

Does anyone know how well Verio is connected in the Equinix sites? Would they recommend them for GigE capacity links, there or in general. I haven't explored Verio in a couple of years, but they seem to be a stable company with a good network. I know they had a change when NTT took the reigns. Thoughts? Comments? on doing business with them? Mostly from a technical standpoint please. Reachability, latency, loss, burst capacity in regards to Verio specifically. We do > 1GB regularly on diverse links and have seen gig links burst to 70-80% for a particular site. Commentary on Williams WCG would be a bonus. -flint

None
by Harsha Narayan 12 Nov '02

12 Nov '02

Hi, Can anyone please tell me the answer to the following question? How do ISPs manage the allocations they get from the RIRs? More specifically, do they make the assignments from this sequentially or not? Are multihoming assignments to customers amidst non-multihoming assignments? I ask this because /23s and /24s seem to be scattered over a wide area - they are not adjacent to each other. Harsha.

Distinguishing multihoming from traffic engg.
by Harsha Narayan 12 Nov '02

12 Nov '02

Hi, How does one find out if a prefix is due to multihoming or traffic engineering if the Origin AS is different from that of the parent prefix and there is no Origin AS path-prepending? (apart from looking up whois) Even if there is Origin AS path-prepending how do we know that the prefix is due to traffic engineering and not due to multihoming? Roughly what percentage of prefixes which are holes that have an Origin AS different from that of the parent would be due to due to multihoming? Harsha.
