RE: MGE UPS Systems
We have 3 big Comet systems, and we're absolutely delighted with them. Their service is the best we receive from any vendor we deal with. I'll second that. We have a 50 KVA MGE Comet and it has been rock solid, and their support is excellent.
RE: one shot remote root for linux?
Cisco ASA's appear to be linux under the hood based on watching versions of ASA804-3/12/19/23/31 boot on the console They are Linux, and run two copies of IOS simultaneously in a VM each. Kind of like how VMWare ESX is Linux - technically it is, but you don't really treat it as such. Not to nit-pick, but VMware ESX uses RedHat Enterprise Linux for it's service console on versions previous to ESXi. The purpose of the service console is to provide support for booting the ESX Hypervisor which itself IS NOT Linux. It does, however, implement a Linux Driver compatability layer so that un-modified Linux drivers can be used w/ the Vmware ESX Hypervisor. The stated goal of this layer is to allow existing third party drivers to be rapidly added to the ESX Hypervisor w/out a lengthy porting process or a requirement for a company to maintain a completely separate driver source code tree for Vmware ESX. Here is a link to some info on Wikipedia: http://en.wikipedia.org/wiki/VMware_ESX_Server Specifically; VMware states that the ESX Server product runs on bare metal.[3] In contrast to other VMware products, it does not run atop a third-party operating system[4], but instead includes its own kernel. Up through the current ESX version 3.5, a Linux kernel is started first[5] and is used to load a variety of specialized virtualization components, including VMware's 'vmkernel' component. This previously-booted Linux kernel then becomes the first running virtual machine and is called the service console. Thus, at normal run-time, the vmkernel is running on the bare computer and the Linux-based service console runs as the first virtual machine (and cannot be terminated or shutdown without shutting down the entire system). It is a common misconception that the ESX Hypervisor is Linux based, but that is an urban legend.
RE: Seeking Connectivity in IRAQ
I've also had good luck with Skycasters (http://www.skycasters.com) but I'm not sure if their coverage extends to that part of the world.
Clueful BGP Engineers
Can someone with a clue from the following two carriers please contact me off list? XO - ASN 2828 Level 3 - ASN 3356 I am currently experiencing a UDP/DNS DOS originating from 165.194.27.159 in Aisia. We have attempted to blackhole the subnet using BGP communities, but the requests are being filtered out at the X/O and L3 interfaces.
RE: Documentation of switch maps
Man.. I'd love to have this for Netgear switches! :) -Original Message- From: Bielawa, Daniel W.

Had a customer come to me this morning who wanted to create a document for their switching infrastructure and thought I would bounce it off the rest of the world on how you usually do this. Typically I use a spreadsheet with outlines to define the switch and then outlines for the ports and color coding for vlan's as well as a description of the port. Curious what other people are doing, as this would be a huge undertaking for a customer who is using an entire /19 of rfc 1918 ip addresses and has well over 150 switches and 40 active vlans. The want to be able to look at this document and pull up any switch and look at the port and be able to see what vlan the port is on, as well as what device it is connected to as well as port channel membership, trunks and other fun things like that. Needless to say their documentation is lacking on the physical connectivity however their cisco infrastructure does have labels on every port that goes to a named device outside of the DHCP pools. Thoughts? Thanks, Blake Pfankuch -- This message has been scanned for viruses and dangerous content by N2Net Mailshield, and is believed to be clean.
RE: All Google Search Results: This site may harm your computer.
This morning whilest Googling, I got a bunch of Permission Denied to /interstitial?... URLs on Google. Then all my search results got listed as This site may harm your computer. Is Google broken, or is the functionality of listing sites as broken, broken? I thought I was going nuts, but yes.. same thing here. From any computer I get the same results.
[NANOG] RackMount DC to AC Inverters
Hello all, I have some equipment going into a Telco Co which only offers battery backup on it's DC power plant. Most of the equipment that is already moving into that facility is AC powered, so I am looking for advice on rackmount DC inverters. Looking for something that can accommodate inverting enough power to load a 30 AMP 110 circuit, preferably something that has N+1 redundancy.. I'm not finding a lot of options on Google, so I figured that I would ask here... ___ NANOG mailing list NANOG@nanog.org http://mailman.nanog.org/mailman/listinfo/nanog
