hi david,

Were these commands run as root?

no.  in this case, this is a shared host (and i recognize that _may_
be a deal-breaker ...). i'm escalated only to "my" user in "my" space
-- i have no real 'root' access.

The --privileged option will fail unless you are root.

admittedly, rying either of the "other" options, namely
'--unprivileged' or (nothing), complains abt that:

  map -d9 -vvvvvvvv -PN -p42000-42100 --send-eth --unprivileged -sU
my.domain.com
    You requested a scan type which requires root privileges.
QUITTING!

  nmap -d9 -vvvvvvvv -PN -p42000-42100 --send-eth -sU my.domain.com
    You requested a scan type which requires root privileges.
QUITTING!

_is_ it at all possible to do "this" sort of nmap scan from a shared host?

Can you read /proc/net/route as root?

as "my" user, no,

 cat /proc/net/route
  cat: /proc/net/route: Permission denied
