Btrfs with Multiple Devices on LUKS
Posted by ebal at 22:33:03 in blog, planet_Sysadmin

I’ve written down some simple (i hope) instructions on creating an encrypted btrfs raid1 disk !

My notes have the form of a mini howto, you can read all about them here:

random MAC address
Posted by ebal at 23:11:16 in blog, planet_Sysadmin

Gnu has a very interesting project for changing your mac address every time you want. I have found it very useful - apparently for security reasons!

The project has the name: macchanger and i will not tell you how to installed it !

I will tell you how i am using it. Become root and type: crontab -e

add the below line

@reboot macchanger -r wlan0 

Now, every time you boot up your machine the mac address on you wireless card will be a random new one !

Happy privacy

GR

Friday 13

17.00 Ο πελάτης επικοινωνεί με το helpdesk, διότι μεταβαίνει σε νέα mail πλατφόρμα και χρειάζεται “ΕΠΕΙΓΟΝ” διαθεσιμότητα μηχανικού 19.00 - 20.00

17.30 Το helpdesk επικοινωνεί με τον standby μηχανικό

19.35 Συνδέεται ο standby μηχανικός για να δει το αίτημα του πελάτη - ΔΕΝ υπάρχει κανένα αίτημα.

Sat 14

00.00 Το helpdesk επικοινωνεί με τον standby μηχανικό, ότι ο πελάτης μόλις έστειλε το αίτημα

00.30 Ενημερώνεται ο πελάτης μέσω helpdesk ότι δεν υπάρχει άμεση διαθεσιμότητα μηχανικού – διευκρινίζεται με τον πελάτη κι επικοινωνείτε σε όλους ότι θα γίνει το πρωί.

10.30 Ο πελάτης επικοινωνεί με το helpdesk για να ολοκληρωθεί το αίτημά του για να μεταβεί στην νέα mail υπηρεσία/πλατφόρμα

11.15 Ο μηχανικός ενημερώνει το helpdesk ότι ο πελάτης ΔΕΝ έχει στείλει κανένα αίτημα. Ο πελάτης αναφέρει απλά “την επιβεβαίωση dns εγγραφών”.

Time at hackerspace
Posted by ebal at 22:23:53 in blog, wiki, archlinux, planet_Sysadmin

I am a very proud member of Athen’s Hackerspace.

I am enjoying the entire 3+ years time (and money) that i’ve spend at this hackerspace. Love it.

Today was a very productive day.

With a good friend of mine, are working to setup an ansible, docker, btrfs workshop !

We want to contribute back to the community and we thought that this is a great opportunity.
We are not guru or anything like that - no, we just want to share the knowledge we are getting by spending time at hackerspace. Nothing more, nothing less. Just share our feedback to all the people that have helped us till now.

So, we are working together (collaboration) by making small steps towards to build these workshop.
Today’s work: Creating a tiny compressed archlinux docker image.

My instruction set is documented here: archlinux installation for docker.

Hopefully my next blog post will be about a simple ssh docker file.
We are trying to keep simple notes so that many people can read and use them.
