#sysop

My beautiful partner asks me to penetrate her box and I get excited.

Then she gives me the address for an OpenBSD server she runs and I get a different kind of excited.

(And then disappointed because it’s locked down tight, but in awe of her sysadmin skills.)

Mistigram: AdeptApril is the System Operator of the Storm Bulletin Board System (pictured above, on a wet day), and has drawn this #ANSIart screen in celebration of International SysOps’ Day. Please leave your appreciation in the oneliners, not the page button!

Thanks for the ask! :D

G: Do you write your story from start to finish, or do you write the scenes out of order?

Sort of both? I skip around a lot when I start a project, but when I’m trying to finish things I work in order.

P: Are you what George R. R. Martin would call an “architect” or a “gardener”? (How much do you plan in advance, versus letting the story unfold as you go?)

Again, I would say a mixture! I try to plan things out as much as I can, but my favorite scenes and lines usually spring up on their own. That’s already happened a few times with my current wip.

Y: A character you want to protect.

Yori, although you wouldn’t know it from the sh!t I put her through lmao. I don’t want bad things to happen to Beck either.

У меня дома стоит пара серверов под управлением vmware esxi. Там в виртуалках много всякого - домашняя лаборатория где я могу потестить всякие штуки, медиасервер plex, обрабатывающий десятитерабайтный архив порн^W фильмов, роутеры внутри виртуалок, и всякое такое.

Машин у меня всего две, FT/HA мне нахуй не нужно (роутеры дублируются через VRRP) и vCenter / VCSA у меня тоже не установлен. Раньше был, но отжирал под себя почти половину сервера.

До этого момента было два способа рулить виртуалками и настройками на esxi:

1) Клиентом. Официально признан устаревшим, особо не обновляется. Существует только под венду.

2) Вебморда vCenter Server / vCSA. Сложна даже в установке, и жрет бешеное кол-во ресурсов в пересчете на одну ноду. И вообще оно нужно только на крупных инсталляциях.

(Тут стоит еще упомянуть vmware workstation, но он позволяет только включать-выключать виртуалки. В потроха ESXi через него не залезешь)

Когда-то давным давно, когда VMWare ESXi еще назывался esx, и внутри него был полноценный (ну, почти) linux, можно было зайти на довольно неплохую вебморду и почти все сделать оттуда. С выходом ESXi (который уже перестал быть линуксом) вебморду куда-то выпилили. Потом вышел vCenter 5.x, в котором вебморду вернули (как отдельный сервис, который являлся частью громадины vCenter Server). Написан он был… на flash. Да-да, том самом flash.

И тут выходит vCenter 6.0 update 02 (да, с версиями у вмвари все странно) куда наконец-то вернули полноценную вебморду. Не прошло и… хотя не, лет 5 прошло.

So I wake up and I do the following without thinking:

• rm -r /main/public/ *

no biggie, I just want that directory gone. —- its taking forever … whyyy?!?!

• computer: you have 20gb of free space.
  
• me: that directory only had 3 gb why do I have so much free space?
  

so it goes like this:

• “rm” is short for REMOVE, meaning DELETE.
• “-r” means do so Recursively, which inturn mean, enter ANY subdirectory and delete all its contents as well.
• “/main/public/” is the directory that I wanted to delete, there was nothing of importance there.
• and finally, the culpit: “ * ” means MATCH EVERYTHING IN PATH.

so the line: “rm -r /main/public/ *“ SHOULD have meant:

• DELETE EVERYTHING RECURSIVELY FROM “/main/public/”.

BUT

I left a SPACE in between “/main/public/” and “ * ”, so you see, “ * ”,  actually means “match anything in path”, in other words, it means:

• SEEK AND DESTROY EVERYTHING IN YOUR PATH.

so this line: “rm -r /main/public/ *“ actually means

• DELETE RECURSIVELY FROM “/main/public” AND SEEK AND DESTROY EVERYTHING IN YOUR PATH.

Had I actually typed “rm -r /main/public/*“, WITHOUT the space between public/ and “ * “, I would’ve achived what I wanted, but I didn’t, I misstyped the command.

DO YOU UNDERSTAND WHAT THAT MEANS?!

I ordered my computer to delete everything in its #$%#$%#$% path!

I’m an idiot and I gave my self the power to actually do so, as such, command WILL BE EXECUTED.

There was a catch however, one that saved my “ass”, and that is that “ * “ matches ANYTHING in this path, well you see, luckily my “path” was “downloads” and not “operative system” or “super important files”.

So my “downloads” directory is now empty as $%$# and its not taking 20GB worth of downloads :DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD!!!! URASHIIII!!! TANOSHIII!!!!

I had a copy of just about everything except foooooor:

• FURUKAWA AIRI GRADUATION STAGE

OHHH MY GRINNING!

I did manage to recover that file since, luckily, I was using it so it had not been deleted unlike the rest of the files.

But I still had some files pending such as Inuzuka Asanas’s and Katou Rumi’s Birthday and something else.

For heavens saaaake.. why do I input such dangerous command as soon as I WAKE UP>!?!?!

Today: System Administrator day :)

Happy new year! I decided to abandon Pinterest and begin using Tumblr in 2013. This month I’ll post to Tumblr the best images from my Pinterest boards, along with all new content.

Introduction to The Holders series

written by Sysop from www.theholders.org

Even though “ls -l” displays a files permissions as “-rw-r–r–”, you can’t use “-rw-r–r–” in a chmod command. This is probably one of the most obvious but overlooked UI inconsistencies in Unix that nobody has fixed after all these years. Instead we force people to learn octal and type 0644. Meanwhile every book on Unix/Linux spends pages explaining octal just for this purpose. Time would have been better spent contributing a patch to chmod.

From Everything Sysadmin: Random technical tips, thoughts and rants

This is one of those oddball UNIX things that no one seems motivated to fix. Kind of how case sensitivity flag is either -f or -s or -i or -c depending on the command, its mode and what you mean by case sensitivity. 

Unix boxes don’t need reboots. Unless there’s absolutely no other option, we’ll spend hours fixing a problem with a running system than give it a reboot. Our thinking here is there’s no reason why a reboot should ever be necessary other than kernel or hardware changes, and a reboot is simply another temporary approach to fixing the problem. If the problem occurred once and was “fixed” by a reboot, it’ll happen again. We’d rather fix the problem than simply pull the plug and wait for the next time.

From Nine traits of the veteran Unix admin

I’ve seen admins start a Virtual machine and route services to that virtual machine while they fix the host server just to avoid having to reboot.
