Fixing SNMPD on Ubuntu

Fixing SNMPD on Ubuntu

SNMP is a foundational protocol for enterprise network and system management. Getting it right shows that a vendor actually cares about servicing IT in the enterprise. Debian, and its downstream progeny, Ubuntu, ship a configuration for the SNMP server, snmpd, that's so broken it positively screams "I don't care".

This brokenness is a known thing. The following bug reports go back to , but nothing has been done to address them:

The following has been tested on both Ubuntu 16.04 LTS and 18.04 LTS.

First steps

Cron job to shut down an idle computer
#!/bin/sh
# This script, intended to be run as a cron job, checks if there are any logins or recent logins and shuts down if there are none. It is not intended to be portable and was written on a Ubuntu 16.04 machine.
last_login_time=$(grep "systemd-logind" /var/log/auth.log | perl -pe "s/ ip.*//" | tail -1 | date --file=/dev/stdin +%s)
if [ $(($cur_time - $last_login_time)) -ge 3600 ] && [ $(who | wc -l) -eq 0 ]
then
init 0

Install MSOffice on Ubuntu

Install Microsoft Office 2010 on Ubuntu

Requirements

We'll install MSOffice using the PlayOnLinux wizard. Additionally, MSOffice requires samba and winbind to properly work.

So, if not installed, install them:

sudo apt-get install playonlinux samba winbind
