status

dhcp is implemented and lightly tested.  bootp is not yet implemented.  enough room for improvement.

about

ip/dhcpd is a dhcpd (it also speaks bootp).  see the manual page for more information.

install

make sure you have $ROOT set.  now run "mk install" to compile and
install the files.

when building from within inferno, insert SYSHOST=Inferno and ROOT=
in the mk invocations to override the values in the mkconfig.

todo

• make Dhcpmsg less ugly
• check that we are serverid from request?
• return multiple dns servers when configured
• if a lease time is requested, and it's lower than the server-assigned (and reasonable), use the clients lease
• honour max message size in request?
• do host->ip conversion on values from ndb that have to be ip in dhcp options? or just require them to be ip's?
• logging?
• implement bootp requests
• dhcp message option overload, for parsing
• respond with unicast in same cases (unless broadcast flag is set)
• broadcast flag must be set for some cases when sending to giaddr
• if giaddr is set in request, allocate address from that subnet? or at least document that we're not doing that.
• test with various dhcp/bootp clients
• probe to-be-handed-out addresses to verify that they really are free?
• make more like plan 9's dhcpd? e.g. dhcp option names.
