NameServer Monitoring System
by joe＠vpop.net 11 Nov '98

11 Nov '98

Howdy folks, I am looking for BETA testers for our "NameServer Monitoring System". (no this does not check the roots to see if they are operational ;-) ) Basically, it watches the roots for changes to the nameservers you monitor and emails you those changes on a daily basis. A sample output is at: http://www.domainwatch.com/monitor/example.html You can monitor up to 10 nameservers. Anyways, if you're interested, do the form bit at: http://www.domainwatch.com/monitor/ and we'll get the instructions out to you. Send bug reports, flames and kudos to admin(a)domainwatch.com Thanks, -joe -- NewsHub: http://www.NewsHub.com/tech/ | DomainSurfer: http://www.DomainSurfer.com/ | Explore Your Net!

Many thanks to my friend & cow-orker Tristan Horn for this idea...in BIND 8 you can define servers as bogus (meaning "don't ever trust these") as follows: // [fjkl].root-servers.net server 192.5.5.241 { bogus yes; }; server 198.41.0.10 { bogus yes; }; server 193.0.14.129 { bogus yes; }; server 198.32.64.12 { bogus yes; }; -- J.D. Falk <jdfalk(a)cp.net> "A name indicates what we seek. Special Agent In Charge (Abuse Issues) An address indicates where it is. Critical Path, Inc. A route indicates how we get there." -- Jon Postel (1943-1998)

gateway failover.
by spam＠eek.org 11 Nov '98

11 Nov '98

i've a situation where the network we're building is very low-traffic, but requires maximum uptime. the budget is for all components to be duplicated to allow for failover. i've figured out various ways to do load-balancing and failover at the router/nat level, and at L2, but have run into a bit of a problem figuring how to use two solaris boxes (firewalls) as gateways for all servers/clients behind them in some kind of HA/failover configuration. i'd like to minimize the client/server side configuration as much as possible (and the environment may include NT, Macs, or other such ilk which will not easily supporting a useful routing protocol), so something like installing gated on all of the boxes, and implementing an ospf environment is an unsavory proposition. i'd like something like HSRP, but for solaris/unix, and preferably free. i'm aware of several vendor HA solutions, but they are mostly overkill for our application. i've looked into IRDP (rfc1256), but i cant find any information about vendor support. any pointers to relevant info would be appreciated, including any general resources for HA/network redundancy/failover stuff (preferably non-commercial). -foo

Cisco IOS 12.0 x 11.1CC
by Rubens Kuhl Jr. 11 Nov '98

11 Nov '98

Have anyone here upgraded a 7500 router from IOS 11.1CC to IOS 12.0 ? If you upgraded, are you happy with it ? ( ) Yes, it supports all the features I was using in 11.1CC ( ) Yes, it supports new features that I'm using now or intend to use ( ) Yes, it supports all cards and/or port adapters ( ) If you upgraded and you are you unhappy with it, why ? ( ) Because it lacks support of features I need ( ) Because it lacks support of card and/or port adapter I have ( ) Because it makes CPU go 100% ( ) Because it doesn't work at all ( ) If you have not upgraded, why ? ( ) Have no support contract, costs money ( ) Cisco told me not to do so ( ) My Cisco representative told me not to do so ( ) 11.1CC works very well, why should I risk ( ) I've seen no reason to upgrade (till last week security notice) ( ) Downtime concerns ( ) Rubens Kuhl Jr.

gateway failover.
by foo 11 Nov '98

11 Nov '98

i'm looking for pointers to any resources for doing failover on solaris boxes. i have an environment in which i'd like a pool of servers to use one of two solaris boxes as their gateway, the other box being in hot standby until a failure of the primary box occurs, at which time it would failover. something like HSRP for unix would work nicely, though i've not found anything similar, except for IRDP (rfc1285), however it doesnt seem to be supported by anyone, in so far as i've been able to tell. i'm aware of commercial solutions, but i'm hoping to find something in the public domain as most of them are overkill and/or expensive. i'd like to avoid doing something with gated/ospf (or another suitably featured routing daemon/protocol), as the environment may include NT, 95, and other boxes that dont easily listen to any sufficiently useful routing protocol, as far as i know. i'm open to just about any suggestion, including an L2 solution, except for something that would depend on clientside software, because of the OS limitations. respond privately, and i'll summarize to the list if necessary. -foo

I was quoting someone else and merely replaced the word "network" with "address_allocation."
