dxtr

Until you realized I suck? :D

RandalSchwartz

so then I decided to say something clever.

Pv1

Pv1 steers clear of the OS war.

RandalSchwartz

Uh - I'd be cheering if it was about numbers.

Pv1

Any arp folks around?

RandalSchwartz

I'm happy you have the choice of langauges. And I'm happy that you got Perl to work for you.
However, I'm about the same level of happy if you had said Python or Ruby or even csh.
since the specific language of choice doesn't matter much to me now
maybe that's me just getting old and cynical

dxtr

RandalSchwartz: You're so naive. Ofcourse the choice of language matters. I don't wanna hang out with those Python geeks
dxtr shivers

RandalSchwartz

heh

[12:01]

dxtr

They're cold

[12:01]

RandalSchwartz: http://www.dxtr.cc/~dexter/radiotjanst.pl.txt go ahead and bash it :D
I know it's in Swedish - but still!

[12:13]

RandalSchwartz

I would have just used LWP::Simple
instead of HTTP::Lite
and you need to check the return from open()

[12:18]

dxtr

Hmm.. LWP::Simple
Ahh! LWP::Simple::Mirror? :)
Seems awesome
Though saving the entire page doesn't seem that awesome

[12:20]

RandalSchwartz

no no. just LWP::Simple;
use LWP::Simple qw(get);
my $contents = get "http:...";
far easier :)

dxtr

Yeah, but for a short minute there the mirror function looked like a good idea

RandalSchwartz

shiny objects. :)

dxtr

s/looked/seemed/
Hehe

awyeah

RandalSchwartz: Suddensly it stopped working when I used LWP::Simple :D
Same content, same regex

hello all

[13:00]

dxtr

Hello
RandalSchwartz: In short: LWP::Simple doesn't seem to like UTF-8 :P
Nothing that 'use utf8;' didn't solve though
So nevermind!

up_the_irons

I installed Ubuntu, FreeBSD, and OpenBSD on my new Atom box. I think I'm sticking with OpenBSD. It was the only one where I could do the whole install over the serial port without doing anything special
and when it asks if I want to change the default console to "com0", after install, it really does it through and through. Like, it'll be sure to run a getty for you on /dev/tty00 because it figures you'd probably want that ;) everything else you have to set it up manually
s/everything else/the other OS's I tried/

[13:14]

dxtr

Call me retarded, but how do a serial console work? :)

[13:18]

fink

dxtr: there's a freebsd page on it

[13:19]

dxtr

really?

[13:19]

fink

dxtr: no, i'm totally lying

[13:20]

dxtr

Right

[13:20]

up_the_irons

dxtr: it is used a lot for out of band access, and kernel development debugging, but I only use it for the former

[13:20]

dxtr

up_the_irons: I mainly asked *HOW* it worked. But still :)

[13:21]

up_the_irons

dxtr: you can manage a server over the serial port instead of using monitor / kb (which you won't have if your server is remote). This excludes IPMI of course.

[13:21]

dxtr

I know that far

up_the_irons

dxtr: tell the system to use serial port as console instead of monitor / kb, then you connect with some terminal program
minicom, or kermit
when i connect it straight into my laptop

bob^^

it's especially good if the hardware supports it properly so you can get into the bios over serial too

up_the_irons

or conserver when it is remote
bob^^: yeah i can get bios over serial on the atom

bob^^

perfect :)

up_the_irons

yup

bob^^

supermicro tend to do a pretty good job on stuff like that :D

up_the_irons

yeah, i'm very happy

dxtr

up_the_irons: Abuot conserver
About*
How do one set that up? I've been thinking of something like that for my router

bob^^

what os are you running dxtr ?

dxtr

bob^^: obsd

bob^^

up_the_irons

i tried both CF-SATA as hard disk and WD Caviar Green 1TB. The CF-SATA was flaky, but used virtually no power. the WD green drive used about 7W when active, 2-3W when idle. so not bad for 1TB

dxtr

I mostly need to know what hardware I've gotta buy :)

bob^^

no hardware

up_the_irons

dxtr: how long is a piece of string? your question has no direct answer

bob^^

just need a serial port on the server, and a serial port on your desktop/laptop/whatever
nice power usage on that WD drive up_the_irons :D

[13:25]

fink

up_the_irons: what was the cf's capacity?

[13:25]

bob^^

dxtr: not sure how relevant this will be for openbsd but it might give you an idea of how it works/how it's achieved on freebsd: http://www.freebsd.org/doc/en/books/handbook/serialconsole-setup.html

[13:26]

dxtr

Oh, nevermind me by the way! :) I'm not thinking right now

[13:28]

Ehtyar has quit IRC (Remote host closed the connection)

[13:30]

up_the_irons

bob^^: yeah, i'm impressed with the power. but unless i need the space, i want to get it < 1W

bob^^: so my buddy just lent me his 64G SSD

gonna see how that works tonight
fink: 8GB

[13:33]

fink

up_the_irons: what will you use this low power system for?

[13:34]

up_the_irons

fink: nagios, openvpn, and conserver

[13:34]

fink

ahc ool

[13:35]

up_the_irons

yeah

[13:36]

fink

i'm into domotics

[13:36]

bob^^

nice, i'd be interested to hear how the SSD is on power

[13:41]

RandalSchwartz

I wonder if a buglabs device will run non-linux?

[13:41]

up_the_irons

bob^^: i'll let you know

[13:42]

bob^^

cool :)

homosaur

so i haven't needed a mail server in awhile and when i did it was still back when sendmail was a security nightmare. any suggestion on mail software nowadays?

[14:38]

RandalSchwartz

I run postfix + dovecot
and postgrey and amavisd-new
between those, most of my spam is stopped
postfix has good security, and *sane* config files
but still more knobs than you can ever master in a lifetime

[14:39]

fink

postfix is pretty stable, but the config requires a shitload of research/reading

RandalSchwartz

only if you're doing something unusual
out of the box, it's an ok leafnode

up_the_irons

i use qmail myself, but would not wish that nightmare upon anyone else.

fink

RandalSchwartz: i guess i just need to know what everything does

RandalSchwartz

if you want to relay or something, it's a bit harder

homosaur

postfix was what i have run before, but i want to make sure that it hadn't regressed in quality

RandalSchwartz

it's very up to date
lots of recent changes

fink

up_the_irons: i love tinydns/dnscache, but qmail freaks me out

RandalSchwartz

Wietse is a good guy

up_the_irons

almost everyone i know runs postfix
fink: it's pretty scary

RandalSchwartz

I should get him on FLOSS.
we've had beers together

[14:41]

fink

RandalSchwartz: he's polish?

[14:41]

up_the_irons

fink: but stable and reliable
RandalSchwartz: yeah, you should get him on

[14:41]

homosaur

RandalSchwartz: if anyone can spend and hour interviewing someone about mail servers, it would be you, mate
RandalSchwartz: by the way, i heard about arp from you on twitter, love the service. spending almost half as much as my last vps host

[14:42]

RandalSchwartz

homosaur - good for you
see up_the_irons? they follow me. :)

[14:43]

bob^^

exim is pretty good
needs a bit of learning to configure, but it's always done everything i need (and a lot more)
and with a decent spamassassin/clamav combo it filters out most spam too

[14:43]

up_the_irons

RandalSchwartz: oh I believe it :)

[14:44]

fink

i want to do something with lamson next

[14:47]

bob^^

hmm
a mail exchanger in python :/
surely performance will suck

[14:48]

mike-burns

Python can be fast.

bob^^

no real experience for me, just assuming it'll be slow given it's interpreted

RandalSchwartz

all the mail has to be properly indented.
YAML preferred. :)

fink

bob^^: you're probably right

bob^^

if you want something where the config is pretty much a script file, exim isn't far from that

fink

bob^^: but i'm just not going to do any more C , period

bob^^

heh, can't blame you there :)

fink

life is too short

mike-burns

Haskell is as fast as C. OCaML comes pretty close.
You're not stuck with C if you want speed.

RandalSchwartz

JITted smalltalk is close to C

bob^^

i still like pascal

mike-burns

Oh yeah, Smalltalk is fast too.

fink

mike-burns: i want clean, indented ease ;)
