linux pcie show available slots
Today I had a request from our user for add a PCIe SSD card to a server. One option is you walk to this server and open it. This not the best option to check if it a PCIe slot available.
Another option is use your Linux commandline.
You need your server mainboard manual to see which slot is labeled.
You have only to check under current usage is in use or available.

Linux Kernel 4.13 change standard mount options for smb 1
Hello,
good news. You are using Linux with Kernel 4.13 so that can happend that you get a mount error by mounting a smb share. Why happend this?
You are mounting a SMB 1 share.
Since Kernel 4.13 it will be tried to mount with version 3.
See git commit
You should use SMB in Version 2.1 or higher
SMB 1.0 is broken, see blog post from Microsoft

Linux Dump eines Prozesses erstellen
Hallo,
das klingt für viele jetzt erstmal total schwer. Es ist überhaupt nicht schwer.
Nutzt das Tool gcore und folgendes Kommando
gcore -o /tmp/dump 12375 (PID ID)
Dann schreibt er den Core Dump. Schaut das auch genug Platz da ist, den soviel Speicher wie der Prozess im RAM belegt wird auch in etwa auf der Platte benötigt.

Man nehme das Paket xrdp unter Debian und schon geht es per RDP Client auf den Rechner
