Dispatches From The Geeks

News and Announcements from the MCS Systems Group

Issue with wired desktop network

Late last week, we instituted a change in the network configuration for desktop networks. This particular change came with an unintended side effect that is resulting in some people’s computers not getting an address from the network when plugged in. In the past, if a host was not registered with us and was plugged into the network, it would get a “Visitor Network” address. Due to this configuration, people got accustomed to plugging in any device and having it work (though you would not get trusted access to lab resources such as inside.anl.gov).

For reasons we have yet to determine, this behavior is no longer being followed. We’re working with CIS to get it fixed, but in the interim the workaround is to register any unregistered machine. We should have announced this sooner, but we expected it to be fixed any day now. Alas, “any day now” has been stretching on for far too long.

If you have a computer that stopped being able to use the wired network, please fill out the following form, and we’ll get it registered as quickly as we can.

We have identified a small number of hosts that *are* properly registered, but are not getting an address. We’re also working with CIS on rectifying those issues.

Sorry for the trouble, everyone. We’ll send an update when it’s fixed.
