My ADSL connection went down for quite a while recently, but I managed to use a Telstra 4G USB Stick with my Raspberry Pi as a secondary internet link to tide me over until my ADSL was restored.

I’ve had my Toshiba Satellite L750D laptop for quite a few years and when I first had it, the battery would show up in the battery meter in Ubuntu. Over the years and after a few Ubuntu upgrades, the battery just disappeared. The system wouldn’t detect the battery at all anymore. I tried all sorts of things to get it to discover the battery, reinserting, restarting, reinstalling, re-everything-else too, but it just wouldn’t show up.

I finally set up my NodePhone service on my FreePBX/Asterisk server after telling myself to do it for a while.
There wasn’t a lot of concrete information out there but through lots of Googling I figured out enough to set it up via the Web GUI.
The following settings are the ones I used to set up the trunk –
Trunk Name: Internode
Outbound Caller ID: Your Internode DID Number
Everything between Outbound CallerID and the Outgoing Settings can be left as default.
Under Outgoing Settings, I’ve used the following settings, however since my Asterisk server is behind a NAT, I’ve set nat=yes on both Peer details and User Details. If your Asterisk server isn’t behind a NAT, you shouldn’t need those settings.
Trunk Name: nodephone
PEER Details
context=from-trunk
type=peer
username=[YOUR NUMBER]
fromuser=[YOUR NUMBER]
secret=[YOUR SECRET]
fromdomain=sip.internode.on.net
host=sip.internode.on.net
dtmfmode=rfc2833
disallow=all
allow=alaw&ulaw
nat=yes
insecure=very
For Incoming settings:
User Context: [YOUR NUMBER]
User Details:
context=from-trunk
host=sip.internode.on.net
secret=[YOUR SECRET]
type=peer
username=[YOUR NUMBER]
insecure=invite
nat=yes
For the Registration:
Register String: [YOUR NUMBER]:[YOUR PASSWORD]@sip.internode.on.net/[YOUR NUMBER]
These settings should get your trunk up and running.

I wanted to monitor the ntpd and python processes on one of my servers so that I would know if one of them went down.
I already had Zabbix and SNMP monitoring setup on this server so decided to have a play around with SNMP Process monitoring.

I have a ProxMox hypervisor host with a disk setup as LVM thin provisioning. This means that I could potentially fill up the LVM partition and run out of space, the guests won’t be able to write to disk, and it’ll all come crashing down…or already has.
