XenServer 6.5 SP1, Dell OpenManage and SNMP.

I've written before about XenServer 6.2, Dell OpenManager and SNMP and XenServer 6.1, Dell OpenManage and SNMP. I'm happy to report that the steps also work on XenServer 6.5 SP1 with very few modifications.

Logitech Media Server and Ubuntu Server 14.04.1 LTS

Logitech Media Server (LMS) was formerly known as SqueezeboxServer, SqueezeCenter and SlimServer. It's been running fine on my Ubuntu Server 13.10 box. I've recently decided to take the plunge and update to 14.04.1 LTS. There were some minor issues, but nothing critical, except for Logitech Media Server which refused to start.

XenServer 6.2, Dell OpenManage and SNMP

I've written before about XenServer 6.1, Dell OpenManage and SNMP. I'm happy to report that the exact same steps also work on XenServer 6.2 SP1.

Guest network with authentication on a Cisco ASA 5505

In case you need to set up an isolated network gut guest access on an ASA, here is a quick guide how to do that. The goal is to have HTTP authentication on the ASA itself before any network traffic is allowed and to isolate the guest-network from any other networks.

rancid and relays using usercmd patch

As I've blogged before, rancid is a really awesome new cisco config differ.

I monitor about 100 devices, and all was well so far.
Now I've come across a device that I can't reach directly from my rancid host. It's not possible to create a direct network connection, or to use ssh tunnels or netcat to forward those ports using a relay host.
Instead I found a much simpler and more elegant solution. Albeit this involves patching rancid.
