Cisco 2960X series Gigabit ethernet switches [Cisco 2960-X switch] New (to me) switch from eBay, cost all of £5.00 inc postage... Gigabit on all ports and POE but just a bit different to the previous 3750's I had. In addition to the 24 (or 48) copper RJ-45, there are 4x SFP and an additional fastEthernet port intended for out of band management, no POE unsurprisingly. Also there is a Mini USB for serial as well as the RJ-45 serial console. This presents as

SR201 network controlled module The SR-201 module is a widely available ethernet connected relay module. It is advertised as being “web controlled” in many outlets, but as I found out, it's not. I have written some python to allow it to be controlled via MQTT, this is available on Git Hub here:-000

Cisco 1921 Gigabit router Background [Cisco 1921] Replaces Cisco ADSL & 1841 router as this is a Fast Ethernet only router, the 1921 is a similar router but with Ge0/0 and Ge0/1 interfaces and two hwic slots. I have a EHWIC-1GE-SFP-CU card as well because in the foreseeable future I may need to bring the internet in from the ISP ONT some distance away, so a utp to fibre next to the ONT would link to the WIC SFP port.000

IPv6 Why there are no new IPv4 jokes? Because they're all exhausted! Just a messing about page for me. Addresses here are not mine.... Just random ones. The Google Public DNS IPv6 addresses are as follows: 2001:4860:4860::8888 2001:4860:4860::8844
