dwheele@joshua:~$ uname -a Linux joshua 6.1.0-15-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.66-1 (2023-12-09) x86_64 GNU/Linux
[as of 9/10/2025]
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
| Start | sudo systemctl start oracle-xe-18c |
|---|---|
| Stop | sudo systemctl stop oracle-xe-18c |
| Restart | sudo systemctl restart oracle-xe-18c |
| Problem | Could not access outside of the local network |
|---|---|
| Solution | Made change to NetworkManager.conf (added dns=none in the [main] section) to turn off its overwriting of /etc/resolv.conf, followed by creating the resolv.conf file to have literally nameserver 192.168.0.1 |

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)

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
Reason? This error occurs because the SHA RSA 1 algorithm that DeployHQ traditionally used for key generation, is no longer supported out the box in newer Linux systems.
Ran this:
sudo apt full-upgrade
Errors were encountered while processing: linux-image-6.1.0-13-amd64 linux-headers-6.1.0-13-amd64 linux-headers-amd64 linux-image-amd64 E: Sub-process /usr/bin/dpkg returned an error code (1)
Trying this:
sudo apt remove aufs-dkms
I bought a large external HDD, modified fstab incorrectly. Kept getting errors on start up.
It kept asking me for the root password for maintenance. Unfortunately I didn't supply the right one (see usual KeePass for the server name). That allowed me to edit the /etc/fstab value to look like this instead:
UUID=135260b9-26cd-41b9-8e69-9489a5d3fe32 /var/nas2 auto rw,user 0 1
(I had left off the rw,user value, causing the 0 and 1 to be in the wrong positions. [5/6/2025])
