[08:44]
ballenor just order some straight caffine from a chemical supply house
nice
[08:45]
sroutegutted 1/2 our main floor earlier this summer; putting Humpty-Dumpty back together again now... [08:45]
ballenright on [08:48]
sroute50kg of bulk caffeine is almost $2000 https://www.spectrumchemical.com/OA_HTML/ibeCCtpItmDspRte.jsp?section_name=Food--Beverage-Ingredients&minisite=10020&respid=50577&item=78509&section=15826&beginIndex=0 [08:48]
ballenFYI: 10 grams of caffeine is lethal [08:49]
srouteProbably a lifetime supply and then some [08:49]
ballen50 kilos, hell
wonder what people use it for
[08:49]
srouteFood production
And science nuts: http://scienceblogs.com/developingintelligence/2008/02/optimally_wired_a_caffeine_use.php
lol
[08:50]
ballenfrom a chemical supply house?
seems like there would be a cheaper place to get it from for food
[08:50]
sroutewas in the food chemicals section. No doubt a big chunk of the population get more of their "nutrients" that way these days ;) [08:51]
ballenheh
I've used caffeinated soap before
kinda dumb
[08:52]
sroutesroute scratches head [08:52]
mike-burnsIf you really hate both your body and sleep, I recommend the uberman polyphasic sleep schedule.
25 minutes every four hours.
It's all you need, really.
[08:53]
srouteSounds interesting. This quote however is what I expected to find quickly: "It is important to note that there are no studies as to the long-term physical or physiological impact of this sleep cycle. I really don't know if this cycle is causing long-term damage to myself or not, and if this concerns you, I wouldn't attempt the cycle. " [08:56]
ballenheh [08:56]
mike-burnsThat's pretty accurate. [08:56]
srouteIt seems that as a general rule it isn't nice to fool with Mother Nature. [08:56]
mike-burnsI blogged my attempt at it here: http://fucksleep.wordpress.com/ [08:56]
srouteQuote is from here: http://www.kuro5hin.org/story/2002/4/15/103358/720 [08:57]
mike-burnsYeah.
One thing you'd discover if you attempted such a schedule is that you now have way more time in the day than you'd expect, and not enough energy to use it. So you quickly read everything about it.
[08:57]
srouteAs I age I'm finding I need more but I still attempt to work the hours I used to.
Kitchen guys are here. Gotta run

jeevgetting annoying brute forces
probably gonna change ssh port
[12:56]
nerddYou could also just use restrictions in /etc/hosts.allow - those denied won't even get a chance to authenticate [13:05]
jeevnever read about it
thought hosts.allow was of known things
ips and what not
[13:06]
nerddYou can both allow and deny hosts access in hosts.allow - e.g. allow connections from only your ip and denying it from all others
Or you can install denyhosts, that monitors /var/log/auth.log and based on rules you configure add and remove ips in the hosts.allow
[13:08]
bithashjeev: you could also try bruteblock, its a nifty little tool that can be custom configured to add IPs to to the firewall based on parameters set by you. [13:13]
jeevusing bruteblock
but it's a million random ips
coming slowly
yea i know neerd
i'll just change the port, i dont care
[13:18]
bithashok [13:19]
nerddI've got to check bruteblock out - I didn't know about that. Sounds cool [13:20]
bithashnerdd: I also use it for apache
but I assume you are using ipfw
[13:21]
nerddI've actually never tried using ipfw for anything yet [13:23]

scratch the last ?
[18:20]
Nat_UBBeBoo...u find them? [18:20]
BeBoo_find what? i need them. i changed my resolv.conf and never wrote down the IPs [18:21]
ballenballen shrugs, uses OpenDNS [18:21]
Nat_UBBeBoo...I only have one...sent via PM [18:22]
BeBoo_thanks [18:23]
Nat_UBNat_UB uses OpenDNS typically...haven't modified this VPS yet [18:23]
BeBoo_but wouldn't resolutions be quicker if it stayed on the same network rather than leaving the network to go to opendns?
i'm sure the time difference would be negligable
[18:24]
ballenactually I found it was faster to use opendns [18:25]
Nat_UBDepends on how fast / overloaded the local might get... [18:25]
BeBoo_i use opendns here at home... was just thinking it might be better to keep it local, is all
thanks =]
[18:26]
Nat_UBOnly use IP's...eliminates DNS slowness [18:26]
BeBoo_of course [18:27]
jeevwhy not run your own cache [18:36]
ballenjeev: if you don't want to use the memory [18:37]
jeevi see
sometimes i dont think
i really need to make time to redo some of my servers, secure, passwords and all
i have maybe 75 outdated servers now
security ones.

BeBoo_anyone good with bash scripting? I have a simple question if i may [19:28]
ballenshoot [19:28]
BeBoo_i'm not sure it's possible with bash but i'm hoping. I know i can echo stuff out. if there a way to... delete what was just echoed and reuse the line?
sorry if i confuse you... not sure how to reword it
Like, i want to echo "Configuring..." then replace that with "Building..."
without using like 10 lines
[19:29]
ballenso
is Configuring... a variable
or stored as a var
[19:31]
BeBoo_it could be
i know how to set vars
thats not what i am asking, tho
i'm talking about output.
[19:31]
ballenohhh
so you literally want a way
[19:32]
sroutejeev: to stop brute force implement pf -- firewall. I have it on all my servers, except for those that sit behind a firewall themselves. Easy. [19:32]
ballenfor echo "Configuring..." to output building... [19:32]
BeBoo_no
-_-
[19:32]
ballensigh... [19:32]
BeBoo_lemme try it this way...
user runs the script...
[19:32]
ballenk [19:33]
BeBoo_echo "Welcome! Gonna build..."
then i would echo "Configuring..."
[19:33]
sroutehere's the relevant line for pf config - automatically shoves offenders into a block table after four attempts within a certain period of time
pass in quick proto { tcp, udp } from any to any port ssh flags S/SA keep state (max-src-conn 15, max-src-conn-rate 4/30, overload <ssh-offenders> flush )
[19:33]
BeBoo_when it's done instead of echoing "Building..." below COnfiguring... i want it to replace that line
remove configuring... and repalce it with building....
[19:33]
ballenohhhh
yea no idea how to do that
[19:34]
BeBoo_k
i don't even know what to call it
lol
[19:34]

N00B_network simulator
ns-2/3
[19:38]
BeBoo_not me sorry [19:39]
N00B_but you know networking...right?
it may seem trivial but i'm having some trouble understanding something..
Just a quick question: i'm running the most basic setup of 2 computers with a single link. Lets say i have a link delay of 1000ms running on a 1Mbps, packet of 500 and packet time every 0.005 seconds. What role exactly is the link delay playing in this situation?
[19:39]
ballenballen shrugs [19:41]
N00B_what channel is this? [19:41]
ballenArp Networks is a VPS, hosting, and colo provider [19:41]
N00B_r u guys into sales or something? [19:41]
ballenhah no [19:42]
up_the_ironsN00B_: read your networking book and learn something; no pasting homework questions ;) [19:42]
N00B_lol [19:43]
up_the_ironsballen: a name like "arp networks" has got me college text book questions emailed to me over the years, I know how this goes :) [19:43]

up_the_ironssroute: i like that pf command
up_the_irons writes it down
[19:44]
N00B_..okay cool :) [19:45]
up_the_ironssroute: i do the same thing on my VM host machines, every VM is actually already protected (after 10 SYN's for SSH within a minute, you're blocked for 1 minute) [19:45]
ballenup_the_irons: why not just turn off password auth
and not worry about it
[19:45]
up_the_ironsballen: it is, but this is for downstream VMs
can't be sure every customer turns off password auth
[19:46]
ballenahh [19:46]
BeBoo_keys are the devil
;x
[19:46]
up_the_ironsa way to help them protect themselves [19:46]
ballenso you have some built in firewall rules that protects us all
well not built-in
you know what i mean

jeevup_the_irons
you dont set kern.hz for customers ?
it slows down ones CPU but..
it's suggested in bsd's manual for freebsd guest
[20:02]
up_the_ironslink? [20:02]
ballenthats it set to now by default in 7.2
thought they fixed that
[20:03]
jeevhttp://www.freebsd.org/doc/en/books/handbook/virtualization-guest.html
pretty much mentioned for every type
[20:03]
up_the_ironsi don't set kern.hz, for the record [20:03]
jeevi've done tests with and witout
without
[20:03]
ballensysctl -a | grep kern.hz
kern.hz: 1000
[20:03]
jeevThe most important step is to reduce the kern.hz tunable to reduce the CPU utilization of FreeBSD under the Parallels environment. This is accomplished by adding the following line to /boot/loader.conf:
kern.hz=100
Without this setting, an idle FreeBSD Parallels guest OS will use roughly 15% of the CPU of a single processor iMacŪ. After this change the usage will be closer to a mere 5%.
guess it allows you to sell more
[20:03]

***heavysixer has joined #arpnetworks [21:07]
mike-burnsBeBoo_: So far as I know (which isn't much) you need ncurses to do what you want.
However the r idea is promising. Maybe 'echo -n' is what you want, too.
[21:10]
visininnah you don't
basically
ugh, this pastebin is garbage
printf("e[K"); /* this escape code erases from the right-side of the cursor to the end of the line */
[21:10]
BeBoo_mike-burns: already am using -en
but if the second line is shorter than the first it looks weird
[21:11]
visininah, you're doing this with bash? [21:11]
BeBoo_like blah blahah
yes
printf works in bash
doesn't it?
[21:11]
visininthat escape sequence might not
hold on just a sec
[21:12]
BeBoo_oh [21:12]
visininyou should be able to just
echo -ne "033[K"

BeBoo_it downloads, configures and installs eggdrop without any interaction [22:42]
ballencoool [22:43]
BeBoo_just confirms a yes/no if you want to do it
also backs up an older install if there is one
so no data loss
