The industry is trying to standardize a settlement process through which carriers would sort out who gets paid when a customer roams from one service area to another.

In the meantime,aggregators and clearinghouses are stepping in. They partner with multiple wireless LAN service providers, aggregate the players’networks to create a merged footprint and put a common brand on the services.

At the heart of both the value and the vulnerability of power substation communication is the ability to remotely access protection, control, automation, and SCADA equipment. These communications are becoming increasingly important to the engineering and operations staff of utilities, yet they may leave systems vulnerable to electronic intrusion.

@ Five things I’ve learned from the TriLUG mailing list over the past few weeks:
• fsck has a “-f” option to force an fsck

you’ve just installed a new wireless local area network (WLAN) in your small business or home. The access point is on and connected, the client PCs are connected to the access point, allowing you to connect to others and the Internet without worrying about wires.

But unlike a wired network, you can’t tell if an unauthorised person has accessed your WLAN. With WLANs you are using radio frequencies that in clear air have a range of up to 300 metres, so could somebody else be connecting into your system from the next street?
