RE: Network Monitoring System - Recommendations?
We actually use it now and its fine for what it does - however, I don't think it provides a real integrated solution. -Charlie _____ From: Erik Amundson [mailto:chauncy@myevilempire.net] Sent: Thursday, November 04, 2004 11:21 AM To: Richard J.

Not a lot of people seem to be using it, but at my organization, we just love WhatsUp Gold by IPSwitch. We first started using it about 4 years ago, when it was a very simple product that pretty much just did SNMP and ping-polling. Now, it's a much more advanced system that can do loads of things... Check it out....www.ipswitch.com - Erik _____ From: owner-nanog@merit.edu on behalf of Richard J. Sears Sent: Thu 11/4/2004 9:11 AM To: Charlie Khanna - NextWeb Cc: nanog@merit.edu Subject: Re: Network Monitoring System - Recommendations? Hi Charlie - We use JFFNMS here (http://www.jffnms.org/). We have it monitoring BGP with our 6 backbone providers, all of our T1's (300 or so), DSL lines, dedicated servers, backing up all of our router configs, talking to our F5s, pretty much everything you are asking for. We use it extensively to grab traps and notify my NOC of any problems. Overall I would say that it is monitoring over 15,000 connections and pieces of hardware. We have its bandwidth monitoring and tracking talking directly to our billing engine and allow our customers the ability to log into it and view all of their stats as well. We don't use it to monitor uptime as we utilize different hardware for that but my guess is that with some minor tweaking it could do that as well. Hope this helps.

Hi - I was interested in finding out what software applications other ISPs are using for network monitoring? For example:
1) Overall network health - uptime reports
2) Backup router config automatically
3) Bandwidth reporting (or integration with an MRTG-type app)
4) SNMP trap support (BGP/OSPF session drops - emails out)
5) Database back end (port info into or over to other apps)
I'm just looking for something well rounded for a small ISP. I've heard about OpenNMS and other apps but I'd like to get everyone's feedback. Thanks!

Look at the official list(tm): http://www.iana.org/assignments/ipv4-address-space
2/ Can I block it in the firewall for "255.255.255.255/32 - Broadcast"?
deny ip from any to 255.255.255.255/32 deny ip from 255.255.255.255/32 to any
You can block anything you like
3/ I got the following. ls it normail? why there is connection to the broadcast address
tcp 0 1 202.64.230.8:33397 192.168.255.255:25 SYN_SENT
255.255 or anything ending in 255 doesn't need to be a broadcast interface. Welcome to the wonderful world of CIDR :) I guess you might want to take a look at: http://www.cymru.com/Bogons/index.html Greets, Jeroen

This is probably a bounce headed toward deliberately broken MXes - anyone else seeing a lot of this lately? (tons of domains with conspicuously common nameservers, serving up unreachable A/MX and hosing queues) J. -- Jess Kitchen ^ burstfire.net[works] _25492$ | www.burstfire.net.uk
