  • I was actually impressed when I took a bus across state lines in the U.S. recently.

    Someone was complaining about the charger on their seat not working.

    Turns out that the driver has full control of the power to the USB ports on the bus and can turn them off and on at will… and they apparently they turn them off BY DEFAULT.

    If someone WERE to figure out a way to get from the USB port in the seats to the CAN Bus on the vehicle itself, having a hard-wired physical switch that cuts power/signal to the ports is potentially a fairly effective security measure as long as there’s not a memory buffer you can compromise and run stuff from.



  • okay, so you’ve got 10 employees with MS licensing. They have e-mail addresses through their microsoft licensing, correct? Those e-mails go through an exchange server? (whether on-premises or exchange online, right?)

    The other 30 employees have e-mail using…what, exactly? (What kind of mail server?)

    Because that Microsoft doc is typically used to set up stuff like scan-to-email for copiers and although you can do other things with relays, knowing the precise setup (without the exact domain names, just use domain1.com, domain2.com or whatever) is important here in order to get the MX records and any relays pointing at the servers where the addresses reside.

    554 does seem to indicate a configuration or permissions issue, but to go down that route, I’d need a little more info about the non-microsoft side of things.
