Sometimes with a VPS provider that uses a really minimal Debian or Ubuntu image, you can get the following message after installing and running tmux
tmux: need UTF-8 locale (LC_CTYPE) but have ANSI_X3.4-1968
To fix, run:
localectl set-locale LANG=en_US.UTF-8
Then uncomment
en_US.UTF-8
from /etc/locale.conf
Then run:
locale-gen
After a Debian Jessie update clamav-daemon starts spouting out:
(!)connect to /var/run/clamav/clamd.ctl failed, attempt #1: Can't connect to a UNIX socket /var/run/clamav/clamd.ctl: No such file or directory
To correct, edit /etc/clamav/clamd.conf and comment out (so that it looks like follows)
#AllowSupplementaryGroups true
And then restart the clam daemon with
service clamav-daemon restart
When you add your pubkey to an openssh server’s config in ~/.ssh/authorized_keys permissions are important or it will ignore your login attempt.
Lock down .ssh directory
chmod 700 ~/.ssh chmod 600 ~/.ssh/authorized_keys
Lock down home directory
chmod g-w,o-w /home/USERNAME
Should let you back in.
Running an apt-get update or an apt-get install occasionally times out on VMs that I am building before I have setup IPv6. Instead of waiting the (seemingly) long time for it to timeout, just add:
-o Acquire::ForceIPv4=true
to the end of the apt-get command to force IPv4.
And to make it permanent:
create /etc/apt/apt.conf.d/99force-ipv4 and put in it:
Acquire::ForceIPv4 "true";
When adding a disk back to an mdadm array I got this error for the md0 array which was actually my swap partition.
root@mothership2 ~ # mdadm --manage /dev/md0 --add /dev/sdb1 mdadm: Cannot get array info for /dev/md0
To fix this you have to run:
mdadm --stop /dev/md0 mdadm --assemble --scan
Then you can add the drive to array like so:
mdadm --manage /dev/md0 --add /dev/sdb1 mdadm: added /dev/sdb1 You have new mail in /var/mail/root
After installing xorg and xorg-tools packages in arch, still missing startx.
You have to install:
pacman -S xorg-xinit
If you try to sudo apt-get install iptables-persistent on you may get this error:
root@mothership:~# apt-get install netfilter-persistent Reading package lists... Done Building dependency tree Reading state information... Done netfilter-persistent is already the newest version.

To resolve you have to edit the file:
/usr/lib/modules-load.d/ipmievd.conf
and comment out like so:
#ipmi_devintf #ipmi_msghandler #ipmi_poweroff #ipmi_si #ipmi_watchdog
then reboot
After you sudo apt-get install nginx-full and you get this:

All you need to do is remove:
listen [::]:80 default_server;
from /etc/nginx/sites-enabled/default.
This is caused if you server does not support IPv6 but nignx is trying to listen on it.
After installing node.js and npm and you go to run a node application you get this error:
sh: 1: node: not found npm ERR! error installing chokidar@0.4.0 npm WARN This failure might be due to the use of legacy binary "node" npm WARN For further explanations, please read npm WARN /usr/share/doc/nodejs/README.Debian npm WARN
This is because in debian nodejs installs to /usr/bin/nodejs while the script/program is looking for /usr/bin/node.
To fix just run:
sudo ln -s /usr/bin/nodejs /usr/bin/node
So you created a headless OpenBSD box only to install php-gd or some other packages that still relies on an X library. You need to install xbase. To do so:
ftp http://mirrors.nycbug.org/pub/OpenBSD/5.6/amd64/xbase56.tgz tar -C / -xzphf xbase56.tgz
