Did this: Bought a Cyclades 8-port serial board and stuffed it into a P133. Load $FreeOS and $Term_Program and go at it. Keep in mind that consoled-devices that don't deal well with a serial BREAK may not like it if/when you reboot the console server box. There are usually hardware or software ways around this.
But WTF did you put the UPD and batteries on TOP of the cabinet? They're really Heavy and should the cabinet ever become unsteady (say, while racking a server) your center of gavity is much higher.
Because they cost us money. Bandwidth, CPU, and disk space are NOT free and you, your provider, and the backbone providers are all spending money to handle SPAM. Just because you don't see it on a bill doesn't mean you're not paying for it.
So how much of the software that they used to make the prduct is GPL'd? Sounds like taking it proprietary is going to be a long road while they recreate all of the GPL's components - like the ones that they blame for insecure password storage, etc.
Get the factory service manual for your car - not the cheapie Chiltons or Haynes manuals, but the ones that the dealer uses. These go into great detail on how to fix things the right way, with very tech-like flow charts, trouble trees, etc.
A lot of the same characteristics of fixing computers applies to cars - take a methodical, structured approach to things and RTFM. Make one change at a time and see how it affects things.
You probably shouldn't run snort on RedHat anyway - they specifically mention in the docs that snort is limited on linux - specifically, it can't tell if it's dropping packets or not at the interface.
On the PtP issue: do what other groups have done: Bandwidth limit the PtP prototcols. This way they're not censoring it, and bandwidth is preserved. Many even open up the pipes during otherwise low-traffic hours.
NAILabs is actually the old TIS Labs, i.e. the guys who brought us the Firewall Toolkit (when Marcis Ranum was there). They're pretty much a separate group from what I understand. My old boss works there...
This ic already part of FreeBSD - it's called Dummynet and was built just for this purpose -to throttle bandwidth and introduce latency for testing purposes. Here's a good writeup by the guy who wrote it/maintains it.
I've seen their cage out at Exodus in Virginia. Pretty cool.. They have like 6 racks of servers there - each rack is 80 servers I believe. They use systems from Rackable. Generally in a hosting facility you pay per rackspace and bandwidth -- more servers/rack means less cost/month in space.
Main Entry: statute
Pronunciation: 'sta-(")chüt, -ch&t
Function: noun
Etymology: Middle English, from Old French statut, from Late Latin statutum law, regulation, from Latin, neuter of statutus, past participle of statuere to set up, station, from status position, state
Date: 14th century
1 : a law enacted by the legislative branch of a government
2 : an act of a corporation or of its founder intended as a permanent rule
3 : an international instrument setting up an agency and regulating its scope or authority
Of course, if we had a well-developed caching infrastructure, and people designed sites that cached well then we wouldn't have the bandwith needs in the first place.
I doubt that even the RIAA is that stupid. Any Judge would be able to see that.
It's much more likely though that their numbers are backed up by statistics that basically say that napster users, who statistically buy X cd's a month are now buying X-n CD's a month. That, and/or saying that they're now downloading Y cd's worth a month from Napster and that those downloads would correspond 1:1 to CD purchases in the absence of Napster.

RTFA - noone said it was free - just run by the county like a utility - you don't get free gas/electric/water do you?
Hell, I'm in Frederick, WITHIN THE CITY LIMITS, and can only get IDSL or one-way cable. Hell yes start repeating this.

$20k is jsut the tip of the iceberg - there's also a good revenue stream to be had in those yearly support contracts for the software.
You mean line Wpoison?

Actually, in hi-rise dorms it's much more fun to tie and end off and get in the elevator.

Liebert maked a self-contained rack with built in air conditioning and UPS. Details here.

It runs beautifully on FreeBSD.

Not-for-profit != non-profit -- they're different legal statuses.

So who else has "I'm just a Bill..." from Schoolhouse rock going thru their heads right now?

Uh, that would be statute, not statue.

WTF are you talking about? DSL is a non-switched service - there are no "dial numbers" - you get a single pipe into your chosen ISP's network.
Does anyone know if code to do this has been published anywhere?
