table; arptab.c is really a hacked up version of arp.c that only
supports adding temporary entries. (This stuff is nasty -- I wish I
knew what was so wrong with SIOCSARP/SIOCGARP/etc... that made the
BSD developers decide to take it out.) The idea here is that the
client issuing the rarp is expected to be in the middle of booting
and would therefore be unable to answer arp queries from other machines
on the wire. Having rarpd stuff a temporary entry for the booting
host into the local arp table helps keep arp requests from going unanswered.
Also added ether_print() and ether_ntoa() to the ether_addr.c module.
Eventually I'll get ether_aton() and ether_hostton() written and
then this file can be dropped straight into libc. (Assuming no one
objects, of course. :)
"Yes Virginia, there is a rarpd."
(Before anyone asks, this *not* the rarpd from NetBSD. It did come from
the same place as theirs, however.)
This is a port of the rarpd program included with the tcpdump-2.0
source code (which I finally unearthed after scrounging around
some of the darker corners of the Internet). It's as close to the
original as I could keep it except for the following changes:
- The original program was based on an older version of the Berkeley
Packet Filter which used different filter programming instructions.
Fortunately, an updated RARP packet filter is available right in the
BPF man page so this was easy to fix.
- The old code didn't know how to deal with variable length addresses
in ifreq buffers. This has been fixed.
- Some byte order weirdness had to be fixed. The sanity checks in
rarp_check() needed some htons()es, and the rarp_reply() function
needed to properly set the ether_type field in the ethernet header
to ETHERTYPE_REVARP before transmitting the packet, otherwise
the bytes in ether_type would wind up reversed. It is important to note
that using htons(ETHERTYPE_REVARP) will not work. This is odd, because
the NetBSD rarpd uses htons(ETHERTYPE_REVARP). (Praise be to tcpdump:
I would never have been able to track this silliness down without it.)
- The update_arptab() function has been castrated. It depends on
SIOCSARP which has been deprecated in 4.4BSD. The NetBSD people
don't seem to be using this function either. It wouldn't be too
hard to replace this with equivalent code from arp.c, but it
might not be necessary.
- I put together an ether_ntohost() support function that allows
both local (/etc/ethers) and NIS lookups. This stuff should go
in libc at some point, but nothing else seems to need it for now,
so it can wait a while.
As you may have guessed, you need to have the Berkeley Packet Filter in
your kernel in order to use this program. The good news is that together
with the recently added bootparamd, you can use finally use a FreeBSD
box to boot Sun boxes over the network. (This was my whole motivation
for getting this stuff to work: I have this one subnet that has a whole
bunch of Sun3 X-terminals on it with only two Sun4 workstations, both
of which are locked in peoples' offices. If those two machines crash
(and they do every so often) then none of the X-terms will boot. Now I
can use a spare PC that I have as a boot server. :)
thinking that it would work :( The install program never get a destination
directory. Here is another patch that should also be added. I think this
should be the last one for these makefiles :)
[Note: I realize that there are more things wrong than this, but this should
at least get the tree compiling again! -jkh]

I hope I'm doing this right.
This is an initial version of bootparamd for FreeBSD based on a public
domain rpc.bootparamd implementation by a gentleman named Klas Heggemann.
This program has apparently been around for a while. The README explicitly
lists the code as public domain, so I guess it's safe to use.
This program is needed for booting diskless SunOS and Solaris machines.
rarpd is also required, but that's in the works too.
I have made two changes to this code:
- Implemented NIS lookups. If /etc/bootparams contains a '+' then the
bootparams map is consulted.
- Allow 0.0.0.0 as a user-specified router address. The SunOS rpc.bootparamd
returns this value in many cases.
o Supporting SYNC SIO device (But need a device driver)
- add "set speed sync"
o Fixing bug for Predictor-1 function.
o Add new parameter that re-sent interval for set timeout commands.
o Improving RTT (Round Trip Time) and reducing processor time.
- Previous Timer service was using polling, and now using
SIGALRM ;-)
- A 0.94beta2 will not work correctly....
-- Follows are additinal feature not including 0.94beta2
o Support Proxy ARP
- add "enable/disable proxy" commands
o Marging common routine in CHAP/PAP.
o Enhancing LCP/IPCP log information.
o Support local Authfication connection on port 300x and tty.
- You can set up pair of your "hostname -s" and
password in ppp.secret. if either ppp.secret file nor
your hostname line don't exist, It will notify a message
and working as same as previous version.(Backword compatibility)
- If you did set up them, It's allow connection but nothing to do
except help and passwd command.
- add "passwd yourpasswd" commands
o Support afilter - keep Alive filter that a packet can send/receiving
according to ifilter/ofilter but doesn't count it as preventing idle
timer expires.
- Same syntax of other filters.
o Fixing bugs reported by current user for previous one. Thanks !!

Fixes to ypbind:
- Correctly report the fact that we've bound to a new server when
logging the 'server OK' message.
- Report 'server not responding' just once instead of every
5 seconds while searching for a new server. (Prevents overstuffing
the syslog.)
- Apply patch from Sebstian Strollo to implement '-s' (secure) flag.
ypbind will reject connections from servers that do not originate
from a reserved TCP port.
- Apply patch from Sebastian Strollo to detect when a YP server has
crashed and come back up on a different port number.
This patch fixes the concurrency problem, and adds a possibly useful -f switch
(which you can read about in the man page :-) ). It also removes the absolute
path from the invocation of ctm. I'll write a note about how to use a script
with sendmail and procmail or some such, and people can fix their PATH there.
BTW, this patch changes ctm_rmail.1, ctm_rmail.c and error.c in the ctm_rmail
directory.

If you invoke config with the `-n' flag or have NO_CONFIG_CLOBBER in

some of it wasn't even correct anyway.

just thinking about it.
Two changes need to be made to allow 'config kernel swap generic' to
work properly without requiring any compile-time flags:
/usr/src/usr.sbin/config/mkswapconf.c: we need to define a dummy stub
for the setconf() function to replace the one in swapgeneric.c that
isn't available in non-generic configurations.
/usr/src/sys/i386/i386/autoconf.c: the -a boot flag causes setroot()
to be skipped and lets setconf() prompt the user for a root device.
If you skip setroot() in a non-generic kernel, you could get severely
hosed. To avoid this, we silently ignore the -a flag if rootdev != NODEV.
(rootdev is always initialized to NODEV in swapgeneric.c, so if
we find that rootdev is something other than NODEV, we know we're
not using a generic configuration.)
Support slice numbers in device names. The syntax is `<driver name>
[<unit number>] ['s' <slice number>] [<partition letter>]'. Only
`['s' <slice number>]' is new here. The slice number defaults to 0
so that there is no change in the output from config if this new
feature is not used.
Replace some magic disk numbers by `dk' slice and label macros.
mkswapconf.c:
Improve the output formatting:
Generate <> style includes.
Print minor numbers in hex so that slice numbers are easy to see and edit.
Print the rootdev and dumpdev names in comments like the swapdev names.
The existing ypbind exhibits some truly anti-social behavior. After
initially establishing a binding with an NIS server, the following events
take place:
- ypbind waits for 60 seconds before trying to broadcast a ping again
- after the 60 seconds expires, ypbind sends out broadcasts every 5 seconds
come hell or high water.
These broadcasts travel far and wide, even to NIS servers in other domains
which dutifully log the packets even though they don't respond to them.
This leads to lots of unnecessary traffic and bloated log files.
This behavior has been fixed/changed. Here's what happens now:
- We still broadcast every 5 seconds at startup, just like before.
- Once bound, we send out packets once every 60 seconds to the server
we're bound to AND NO ONE ELSE.
- If we fail to receive a reply from our server within FAIL_THRESHOLD
seconds, we assume our server has croaked and go back to broadcasting
everywhere every 5 seconds again until somebody answers. FAIL_THRESHOLD
is currently set to 20 seconds.
Other fixes/improvements:
- ypbind now logs 'server not responding' and 'server OK' messages where
appropriate.
