where UID==EUID so that perl is not unhappy about a setuid script
being invoked when EUID!=UID.

Added checksums (simple add for now,) as well as Multicast leave-group on exit.

switch to try it out. The main thing missing at this point is a way to tell
frisbee _which_ disk image to load - it will load whichever image there
happens to be a server running for.

for using frisbee to do mass disk-loading.

Note that, unlike bootinfo, this does _not_ include support for clearing
this field, since there does not seem to be a clean way to contact proxydhcpd
to indicate that it can be cleared. This support will most likely be put into
tmcd.

in. Sigh. Took me too long to find this. On the other hand, there is
more debugging and more asserts in the code. Also a -d option to turn
on progressive levels of debugging.

Also changed the operation of imageunzip so that individual slice
writes (ie, to unzip the BSD or Linux partition instead of the entire
disk). Using the slice device (/dev/rda0s1) is actually a problem on
BSD since it snoops writes to where the disklabel should be and alters
the offsets. Even worse, on non BSD partitions it craps out completely
because there is no disk label at all. This is really a dumb
thing. So, I added code to read the MBR when the -s (slice) option is
given, and use the MBR to compute the offsets from the beginning of
the raw disk. Must always use the raw disk device now, and the new
operation is:

	imageunzip all.ndz /dev/rad0
	imageunzip -s 2 rhat.ndz /dev/rad0

Note that if you give a slice instead of a disk device, and there is a
valid looking MBR in the slice (which is very possible), then things
will get very confused. Not sure what to do about that yet.

Added instrumentation, a bit easier to see whats going on in the client now.

Emulab frame.

Modified makefile to create userfrisbee (the client) and frisbeed (the server).
Added support for syslog to f_network.c, using an ugly makefile hack to make multiple versions of the
f_network .o file available (one for the server, with #define SYSLOG prepended, one for the client using
the normal printfs.)

option to get this output. Now also handles multiple machines on the
command line

NOTE: This file now has some Utah-specific information in it. There are
a few variables at the top of the file that should be changed if you
want to use it at another site.

interface ordering

Not exactly what Mike wanted, but this was quick and easy. I'll make
it pretty later (sure you say!).

all it does it provide an email hyperlink to us. But it encourages
people to ask us instead of making a new account!

addresses from the pages. Just one less localization problem. Still
need to deal with all the flux hyperlinks though!

I increased it to 15x70. Sheesh.

same name in the node_types table

ack/nak for a connection so that the connecting process knows what the
hell is going on. Turned out to be necessary for power control since
we do that in parallel, and because it stays busy for 10 seconds on
each power control. I think we will end up revisiting this at some
point, adding blocking connections instead of connect/fail status.

FreeBSD support, except that the CPU speed is determined from /proc/cpuinfo

decl, so that symbols in the used module are in the package namespace.

/etc/testbed/nodetype uses the CPU speed (gleaned from /var/run/dmesg.boot
by cpuspeed.awk) to distinguish between pc600s and pc850s. The start_if.*
scripts use this to determine whether the node should attempt to dhcp
on this interface.

NOTE: When using the start_if.* scripts, NO interfaces should be set
to DHCP in /etc/rc.conf - this will break things.

to use the DB library access routines, which also changed in response
to what the tb scripts needed. Added some functions and mor constants.
Removed the -nologfile option from all the scripts (startexp and
endexp too), since there is no reason for these scripts to worry about
log files. Thats handled in the wrappers. Tested with the testsuite
and live in my own tree.

happening, but the capserver is getting wedged in a read, for a
connected capture, although there was no such capture in the
corresponding state on plastic, that I could find. This should work
though.

goo whenever it goes inactive for more than a couple of minutes. Also,
require that we sync up so that we know for sure that the power
control failed. Previously, I was blindly spitting out the command
without being sure we had a command prompt.

Note, that we still have a problem with an active tip session messing
up power control since only one connection can be active at a time.
At present, there is no positive way to know that the connection was
refused since capture accepts the connection and then closes it if
there is an active tip session. I need to change the little handshake
so that there is a response Yes/Know response to the secret key
exchange.

it returns 0 on success and non-zero on failure.
