taking a day off here mostly... new kitchen counters showing up any minute. Will be happy to stop cooking outside on the patio. | [08:44] |
ballen | or just order some straight caffine from a chemical supply house
nice | [08:45] |
sroute | gutted 1/2 our main floor earlier this summer; putting Humpty-Dumpty back together again now... | [08:45] |
ballen | right on | [08:48] |
sroute | 50kg 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§ion=15826&beginIndex=0 | [08:48] |
ballen | FYI: 10 grams of caffeine is lethal | [08:49] |
sroute | Probably a lifetime supply and then some | [08:49] |
ballen | 50 kilos, hell
wonder what people use it for | [08:49] |
sroute | Food production
And science nuts: http://scienceblogs.com/developingintelligence/2008/02/optimally_wired_a_caffeine_use.php lol | [08:50] |
ballen | from a chemical supply house?
seems like there would be a cheaper place to get it from for food | [08:50] |
sroute | was in the food chemicals section. No doubt a big chunk of the population get more of their "nutrients" that way these days ;) | [08:51] |
ballen | heh
I've used caffeinated soap before kinda dumb | [08:52] |
sroute | sroute scratches head | [08:52] |
mike-burns | If 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] |
sroute | Sounds 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] |
ballen | heh | [08:56] |
mike-burns | That's pretty accurate. | [08:56] |
sroute | It seems that as a general rule it isn't nice to fool with Mother Nature. | [08:56] |
mike-burns | I blogged my attempt at it here: http://fucksleep.wordpress.com/ | [08:56] |
sroute | Quote is from here: http://www.kuro5hin.org/story/2002/4/15/103358/720 | [08:57] |
mike-burns | Yeah.
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] |
sroute | As I age I'm finding I need more but I still attempt to work the hours I used to.

jeev | getting annoying brute forces
probably gonna change ssh port | [12:56] |
nerdd | You could also just use restrictions in /etc/hosts.allow - those denied won't even get a chance to authenticate | [13:05] |
jeev | never read about it
thought hosts.allow was of known things ips and what not | [13:06] |
nerdd | You 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] |
bithash | jeev: 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] |
jeev | using 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] |
bithash | ok | [13:19] |
nerdd | I've got to check bruteblock out - I didn't know about that. Sounds cool | [13:20] |
bithash | nerdd: I also use it for apache
but I assume you are using ipfw | [13:21] |

Nat_UB | BeBoo...u find them? | [18:20] |
BeBoo_ | find what? i need them. i changed my resolv.conf and never wrote down the IPs | [18:21] |
ballen | ballen shrugs, uses OpenDNS | [18:21] |
Nat_UB | BeBoo...I only have one...sent via PM | [18:22] |
BeBoo_ | thanks | [18:23] |
Nat_UB | Nat_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] |
ballen | actually I found it was faster to use opendns | [18:25] |
Nat_UB | Depends 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_UB | Only use IP's...eliminates DNS slowness | [18:26] |
BeBoo_ | of course | [18:27] |
jeev | why not run your own cache | [18:36] |
ballen | jeev: if you don't want to use the memory | [18:37] |

BeBoo_ | anyone good with bash scripting? I have a simple question if i may | [19:28] |
ballen | shoot | [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] |
ballen | so
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] |
ballen | ohhh
so you literally want a way | [19:32] |
sroute | jeev: 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] |
ballen | for echo "Configuring..." to output building... | [19:32] |
BeBoo_ | no
-_- | [19:32] |
ballen | sigh... | [19:32] |
BeBoo_ | lemme try it this way...
user runs the script... | [19:32] |
ballen | k | [19:33] |
BeBoo_ | echo "Welcome! Gonna build..."
then i would echo "Configuring..." | [19:33] |
sroute | here'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] |
ballen | ohhhh
yea no idea how to do that | [19:34] |
BeBoo_ | k
i don't even know what to call it lol | [19:34] |
ballen | replacing text inline on the terminal
without a new line | [19:34] |
BeBoo_ | yeahh there ya go
yess | [19:35] |

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] |

ballen | up_the_irons: why not just turn off password auth
and not worry about it | [19:45] |
up_the_irons | ballen: it is, but this is for downstream VMs
can't be sure every customer turns off password auth | [19:46] |
ballen | ahh | [19:46] |
BeBoo_ | keys are the devil
;x | [19:46] |
up_the_irons | a way to help them protect themselves | [19:46] |
ballen | so you have some built in firewall rules that protects us all
well not built-in you know what i mean | [19:46] |

jeev | up_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_irons | link? | [20:02] |
ballen | thats it set to now by default in 7.2
thought they fixed that | [20:03] |
jeev | http://www.freebsd.org/doc/en/books/handbook/virtualization-guest.html
pretty much mentioned for every type | [20:03] |
up_the_irons | i don't set kern.hz, for the record | [20:03] |
jeev | i've done tests with and witout
without | [20:03] |
ballen | sysctl -a | grep kern.hz
kern.hz: 1000 | [20:03] |
jeev | The 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] |
ballen | I believe there is some issues with setting it lower
performance wise | [20:04] |
jeev | yea | [20:04] |

However the r idea is promising. Maybe 'echo -n' is what you want, too. | [21:10] |
visinin | nah 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] |

but if the second line is shorter than the first it looks weird | [21:11] |

yes printf works in bash doesn't it? | [21:11] |

hold on just a sec | [21:12] |
BeBoo_ | oh | [21:12] |

echo -ne "033[K" that'll clear the rest of the line yeah, that works! | [21:12] |
