Would using the combination of both MD5 and SHA-1 raise the computational bar enough for now, or are there other good prospects for a harder to crack hash? On Sat, Jan 3, 2009 at 9:35 AM, William Warren hescomins...@emmanuelcomputerconsulting.com wrote: Dragos Ruiu wrote: On 2-Jan-09, at

Speaking of AtlantaIX, the new business model seems less attractive for customers than the old one. Can anyone speak to why it got sold? Was it failing financially or someone just wanted to cash out? On 8/12/08, Patrick W. Gilmore [EMAIL PROTECTED] wrote: On Aug 12, 2008, at 3:37 AM, Paul

Ok, it's probably a stupid question, but given the relative ease of putting 4gb+ ram on a 64bit platform, could packet per second performance be improved by brute forcing the route lookup as an array of 1 byte destination interface indexes for a contiguous swath of /32's from bottom to top? Route

I would think that simply requiring some appropriate amount of irrevocable funds (wire transfer, etc) for a deposit that will be forfeited in the case of usage in violation of AUP/contract/etc would be both sufficient and not excessive for allowing port 25 access, etc. On Wed, May 28, 2008 at

Well, give the junky little NAT boxes their due. Grubby little home networks running windoze on one or a few computers cause a lot less trouble in the world when there is a junky little NAT box between the house LAN and the big world outside. Better ways to do it? Absolutely! Easier, cheaper
