Random bits from and related to 2006-06-01 BUUG meeting:

CAPTCHA - yes it's an acronym.  The long form isn't all that catchy, though:
Completely Automated Public Turing Test to Tell Computers and Humans Apart
http://en.wikipedia.org/wiki/Captcha
And some recent related article(s):
http://it.slashdot.org/article.pl?sid=06/06/01/1255215
(I'd mentioned how many CAPTCHAs were getting rather challenging for
humans to decipher ... apparently making it baffling for computers and
easier for humans is a problem that's being worked on.)
And in addition to software that solves various (arguably insufficient)
CAPTCHAs, in at least some circumstances, there are other bypass means, e.g.:
http://yro.slashdot.org/article.pl?sid=04/01/28/1344207&mode=flat
... though that's technically not a CAPTCHA shortfall.

Subject: [buug] DSL 768/768 line with 5 IP's
Message-ID: <44834486.30409@hawaiidakine.com>

Aloha,

I belong to a group of FreeBSD / Mac users who want to learn more of the 
Internet hookups for servers.

We have acquired a DSL Line 768/768 with 5 ip addresses to learn on with
66.xxx.xxx.234 .235 .236 .237 .238
a Sub netmask of 66.xxx.xxx.248

And a Gateway of 66.xxx.xxx.233

The Tech person at the providers end however did not know how I would 
connect and whether the Gateway was mine or there end.

I have a Farallon switch and a Freesco Router to connect the servers to 
the incoming/outgoing dsl modem and to the (possible) 5 Servers.

(I have an existing DSL 1.5 down and 768 up. but it is only 1 IP
(66.xxx.xxx.18) and the gateway  (66.xxx.xxx.1) is at there end not 
ours. It is a BNC lan with a Freesco Router which I have set up and 
maintain.)

I could not get any help from the telcom in how to set this new line up 
to reach them. Our telcom was sold a year ago and we have all new folks 
at there end now.

Has anyone had experience connecting one of these 5 IP DSL lines?
They did say I would not not need the CSU/DSU setup like a T1 would require.

Thanks,
Al Plant

That's a relatively common scenario for multiple static IPv4 IPs over DSL.
There's a /29 mask - 255.255.255.248
There are 8 IPv4 IPs, 5 "useable", and the remaining 3 being the IP for
the network itself, the router, and the broadcast address, respectively.
e.g.:
netmask:    255.255.255.248 (/29)                11111000
network:     66.xxx.xxx.232 (/29)                11101000
gateway:     66.xxx.xxx.233 (default route(r))   11101001
IPv4 1:      66.xxx.xxx.234                      11101010
IPv4 2:      66.xxx.xxx.235                      11101011
IPv4 3:      66.xxx.xxx.236                      11101100
IPv4 4:      66.xxx.xxx.237                      11101101
IPv4 5:      66.xxx.xxx.238                      11101110
broadcast:   66.xxx.xxx.239                      11101111
Sometimes it's a bit easier to see in binary - I included the last
octet in binary above.
The gateway is on "their" end, ... otherwise you wouldn't make it off
of your subnet.
Configuration's relatively straight-forward - set up the netmask, IP,
broadcast, default route, DNS configuration, and in some cases also
network address, for each device - or configure a DHCP server to hand
them out (or some of both).  They should also give you the IPs of DNS
server(s) to use.  Just need a hub or switch between the DSL modem
and the other devices, don't need any fancy NAT/SNAT/masquerading,
etc., unless you don't want the IPs directly reachable from The
Internet and/or need to simultaneously use more than 5 IPv4 devices.
Having the multiple static IPs is generally preferable to a single IP
and multiple devices, but the ISP will typically charge somewhat more
for that.

Subject: [buug] Missing boot loader ...
Message-ID: <448F9D25.2030607@hawaiidakine.com>

I installed FreeBSD 6.1 on 2 different HD's 3.5 GB. When the reboot is 
supposed to happen the Boot loader doesnot come up. Is there a way to 
fix this from a single user prompt or any other way? I have never had 
this happen to FreeBSD and I have been installing it on many boxes since 
  version 3.4.

This box is for a firewall on a small office  lan with only a minimal 
FreeBSD 6.1 installed to run the firewall. It is an HP box Vectra 486/66.

I have looked at several how to's in my FreeBSD reference books, but 
most say put a dos partition on the drive as maybe the bios need to see 
the parameters more clearly. Any Ideas besides that? I do have a box 
that cant run above FreeBSD 4.11 as a print server in an installation. 
But FreeBSD 5* would not install on it at all. This installs but won't boot.

Subject: [buug] WiFi under Ubuntu 6.06 on Compaq Presario M2000 laptop
Message-ID: <44909E12.10506@josephzitt.com>

Hi, folks. I've been running Ubuntu 6.06 on Compaq Presario M2000 
laptop, and almost everything is going well. However, connecting to the 
Net via WiFi is proving a challenge. I've checked a host of references, 
web pages, and manuals, but it works only intermittently, if at all. I 
think it's failing to get a DHCP connection, though I'm uncertain if 
that's just a symptom (and perhaps a misleading one). It does seem to 
behave properly when I boot into Windows, so I think that shows that the 
hardware's OK.

To complicate things, I don't have a Net connection at home, but get on 
at a variety of Internet cafes, with a variety of connections, some open 
and some with WEP and WPA.

Would anyone be willing to sit down with me sometime at one of the many 
downtown Internet joints and help me get it working? I can't afford 
appropriate consulting fees, but I can buy you lunch :-)

I'm online once or twice a day, or you can reach me at my cell phone, 
which is the phone number listed at http://www.josephzitt.com/resume/ . 
(And I should probably update the resume sometime to include what I've 
been doing since 2001 :-] ),

what type of card is it?  are you using networkmanager to deal with it?

are you having trouble with only open hot spots -- or can you even
connect to wep and wpa ones?  A little more detail in general would be
a big help

The M2000 has a built in Broadcom BCM4306 802.11b/g device. I'm using 
the Networking GUI from the Ubuntu menus to handle it -- is that 
networkmanager? I've also tried gtkwifi, but that doesn't seem to do 
anything at all that I can understand.

I'm having some trouble with each (open, WEP, and WPA). I can connect 
slightly more often to open sites, but far from consistently.

Well there's your obvious problem, you have a broadcom chip.  get a
good howto and install  ndiswrapper instead of trying to use the /very
alpha/ broadcom drivers. My personal preference would just to get a
card with decent open source (none of them are particularly Free)
driver that will be more solid.  Sorry about the bummer news.

Yeah, I forgot dapper does networkmanager by default, which is great.
I wish there was an equivalent *bsd option.
