Immediately after I switched to Fedora on my main machine I noticed that I can’t SSH into other machines on my local network via their hostname.
This blog post will talk about how to set up Nvidia proprietary drivers on your Fedora 22 Workstation, or at least how I did it ;-) Detect your Nvidia card model: lspci |grep -i VGA Switch to root (or execute rest of the commands with sudo priviledges: su Update your system and reboot after that: dnf update -y...
I switched to the new Fedora 22 release and it feels good ;-) Here’s screenshot from my laptop:

If you also use it you know what PITA it is to have fullscreen flash in Firefox, especially if you’re using multiple displays.

Scenarij: Instalirali smo poslužitelj te je nakon nekog vremena ponestalo prostora na istom. Ne želimo ništa brisati već želimo proširiti disk, kako to možemo najlakše napraviti?
Zaštititi privatne SSH ključeve snažnom lozinkom je pametna stvar. U slučaju da vam netko uspije ukrasti privatni SSH ključ imate vremena “u miru” zamijeniti isti jer da bi ga koristili trebaju pogoditi i lozinku za otključavanje vašeg privatnog ključa. Prilikom svakog povezivanja putem ssh ili scp programa potrebno...
dig (domain information groper) je alat za slanje upita prema DNS poslužiteljima. Dio je BIND -a i zamjenjuje starije alate poput host i nslookup.
Arch Linux je lagana i fleksibilna Linux distribucija koja se pridržava pet osnovnih principa koje često nazivaju “The Arch Way ”: Jednostavnost Koreknost koda prije praktičnosti User-centric Otvorenost Sloboda Nakon čitanja uvodnog članka na Arch Linux web stranici odmah sam prepoznao da je upravo to distribucija...
