Re: Update Spamhaus DROP list from Cisco CLI (TCL)
I made a version of Mr. Magill's script to read the dshield.org's
block list and create null routes for it. He deserves all of the
credit, but none of the blame in case it doesn't work for you. I'm not
a TCL programmer - use at your own risk.
Anyone else have any nifty TCL for Cisco scripts they can share? I'm
curious to know what's possible and what people have done.

slightly OT: wall mount UPS for demarc
I'm looking to buy several small wall mounted UPS's to power a telco's metro ethernet switches. (Yes, they should have provided some kind of protection, but won't). The closest suitable UPS I've found is this: http://www.tripplite.com/EN/products/model.cfm?txtSeriesID=419&EID=361&txtModelID=3640 Can anyone suggest a better alternative? I want something sturdy, preferably metal, that can screw to a wall and be worry free for years at a time.
