I recently wanted to update my Cisco knowledge so replaced my old Juniper home router with a Cisco 877W ADSL2+ wireless router. I thought I’d share the config for any other UK BEthere.co.uk users with a static IP address:

Once you’re up and running, log a support call with BeThere and ask them to switch your SNR Profile and that’ll raise the speed above the 14mbps you’ll get without it.

Dell have recently released a firmware update for the PowerConnect line of switches to resolve the security vulnerability I discovered.

Firmware version 4.1.0.19 lists the following fix:

Access is allowed to files on the switch without log in permissions required.
If the file name is known, the file can be downloaded through the web browser without having to be logged in.
Corrected the web process to require login credentials before downloading a file.

Looking at the release notes, Dell have certainly had a few problems with these Broadcom switches. Fingers crossed their new Juniper product line has less issues!

You can find the firmware update on the Dell website.

I recently needed to log all calls made via one of our Avaya IP Office phone systems (running software version 5). The only way to do this was via a protocol known as SMDR. This is a process by which the phone system sends call data to another service for recording. I put together a quick Windows service to receive this information and output it to CSV format. Here’s an example of the output (please do not call the numbers in the example):

Call Start, Connected Time, Ring Time, Caller, Call Direction, Dialed Number
