Oh.. you mean services .. not stacks. I read that to mean like
Netware or Appletalk support. I will take a shot at this one. :)

Yes. See libnetworking/rtems_servers.

Yes. There has been some discussion of bootp versus pure dhcp and
a post recently on the mail list.

Yes. A port of ucsd-snmp is in contrib.

Yes. GoAhead in libnetworking/rtems_webserver

These I do not know about. Help!!!

RTEMS replies to pings.

THe ones I answered yes on are either in RTEMS source already and
there is no license or in contrib and need no license.
The GoAhead webserver has a unique license you might want to look at.

Multiple people have ported various pieces. It tends to be a fairly
straightforward task these days to move BSD code to RTEMS if you
follow the pattern the existing network code does. If you port
an add-on package like ucsd-snmp, then it is simply application code
and ports based on its porting layer.
