That makes sense. I was thinking that you would have the backup (new)
IPCop going with DNS caching going (and, naturally, local hosts defined,
local domain defined, ...). Sorry for the confusion.
Unless some unit is a DNS server, or caching sever on the local lan,
that would be a wasted effort.

He-he! A misleading message if there ever was one! IPCop expects that
you have downloaded an update image. Later you can install it. There is
no yum-like facility going on there (from a paranoid security POV that
would be a big NO-NO).
You have to check your version (should appear in the installed updates
section), go to the website and see if there is something new. The
1.4.18 was latest last I looked.

That doesn't show the IPCop software version. From the web interface,
IIRC you can find out the version on one of its screens.
