Purchased a small Intel NUC computer, which has a Intel Core i7 Processor, 8 Gb RAM (32 Gb maximum), 40 Gb SSD as a possible Minecraft server.

dwheele@joshua:~$ uname -a
Linux joshua 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux

Added git with this command:

apt-git install git-all

For work, installed Oracle XE

The download was an rpm, so had to install alien to install the rpm. sudo rpm -i package-to-install.rpm

Also had to install libaio:

sudo apt-get install libaio1

Helpful: to temporarily to restore network service, long enough to install some tools (the ethernet card is “eno1”:

dhclient eno1

This will help troubleshoot network:

# apt-get install ifupdown-extra
 
network-test

After doing some upgrades, server Joshua kept going to sleep. I read this, and tried it:

* https://unix.stackexchange.com/questions/529471/debian-10-adjust-sleep-settings-via-command-line

There is possibly a better way: edit /etc/systemd/sleep.conf and activate the following two lines:

AllowSuspend=no
AllowHibernation=no

Wanted to serve photos to the Oculus from the file system. So installed MiniDLNA, a.k.a. ReadyMedia.

See https://www.bananatronics.org/installation-and-configuration-of-minidlna-readymedia/

sudo apt install minidlna
vi /etc/minidlna.conf (adjusting media_dir=/var/nas/Videos)
sudo service minidlna restart
sudo systemctl enable minidlna (not sure what this does)

Visible from Windows Media Player, Oculus Pigasus, Oculus DeoVR

Received this error in /var/log/auth.log

 sshd[167454]: userauth_pubkey: signature algorithm ssh-rsa not in PubkeyAcceptedAlgorithms 

Fixed by running these:

 
root@someserver~]# vim /etc/ssh/sshd_config
 
// Add this to end of file
PubkeyAcceptedKeyTypes +ssh-rsa
 
root@someserver ~]# systemctl restart sshd
