I was able to get it compiled but still can't get it to work. The address
didn't get taken over by the backup machine as advertised.
I am also looking to hear from someone who had successfully got it to work
on Solaris 8. I would really like to use wackamole with mod_backhand for
load balancing and fault-tolerance. Anyone?

Hi!

Thank you for your interest in Wackamole. Unfortunately, we do not
have access to a Solaris 8 box at the CNDS lab (http://www.cnds.jhu.edu)
at Hopkins, so we cannot currently test it for this architecture.
Most of the Wackamole code is very protable and should work on
any operating system, similar to the Spread toolkit. However, the
part that actually grabs the IPs is VERY system dependent, potentially
to the level of certain kernels.

We could look into the problem if someone can give us access to
a Solaris 8 environment.

Hey,

If someone is even able to spare a solaris 8 box, I am sure
we will be happy to find a power outlet for it in the computer room
of the lab :)

Cheers,

:) Yair.

Thanks for all quick quick reponse. I really
appreciated. As we all know, almost all current
commercial HA implementation have propriatary
components in them. This wackamole thing looks
have pretty good abstraction to me.

Alex,

Can you share some idea with me? Do you have
a makefile? Yair, I will look and see if I
can find a box. You guys are great. It reminds me
of my graduate school days ten years ago.

Thanks.

Min

Min,

I haven't got much time right at the moment, but I should be able
to compile it and provide you with install notes in a few hours.

Where abouts is the compile breaking for you at the moment?

Since I can see Wackamole in action right now,
can you tell me if my understanding is correct
please?

Most LB-type of clusters requires a up-front
function either in the form of hardware(L4 switches)
or software(Resonate, etc) that spreads the ips(
translate virtual IP to physical IP of the nodes.

This Wackamole arbitrates the leader in the membership
amongst the nodes themselves. I assume there is no
shared quorum between them, will IP takeover always
be successful? Particularly when all nodes are down
and
coming back at the same time or "split-brain"?

Any advice is greatly appreciated.

Assuming the Spread daemons and the Wackamole processes work,
there should be no problem. Wackamole relies on the Spread membership
service to know who is alive and connected. This will be in agreement
among all those that are connected. Now, this is a bit delicate
and to fully understand it you will need to understand the
membership semantics Spread provides.

One of the reasons for me to write Wackamole was to demonstrate
how a correct application for the Spread toolkit should be written.
(Other people, of course, had much better reasons - such as writting
cool hacking code that can create havoc in the lab :)

The consistent state engine in Wackamole demonstrates how to
write consistent state agreement in partitionable environments
(environments that can partition to several components or merge,
where ANY events, possibly cascading, of membership changes is
possible). This takes care of any "split-brain" problem, as all
the IP addresses will be covered exactly once, in each of the
partitioned components that contain at least one Wackamole running.

Enjoy,

:) Yair.

ok, I've had time to have a look at the source now, and there
are two problems making it impossible to create the final
binary (all the source comiples relatively cleanly):

1. There is no code for sample_arp_cache for Solaris 8.
It neither compiles under the HAVE_PROC_NET_ARP nor the
CTL_NET define requirements. This function is called from
wackamole.c

2. The same kind of problem for serv_accept, Solaris defines
I_PUSH and under the apue.c defines this function doesn't
get created and control.c requires it.

This kind of programming is well beyond my admin knowledge so
although I could force it to compile relatively cleanly I can't
guarantee the resulting behaviour :-)

Changes required to get the source files compiled:
1. Require GNU Bison and flex
2. After running configure I edited the Makefile and removed the
-I/usr/include from CPPFLAGS (causes alarm.c not to compile)
3. Edited control.c and added #include <sys/filio.h> so that FIOBIN
was defined, otherwise control.c does not compile.

Finally failed with:
gcc -o wackamole wackamole.o alarm.o lex.yy.o y.tab.o arpcache.o
spoofmanager.o abt.o control.o apue.o configuration.o ife-dlpi.o
-L/usr/local/lib -R/usr/local/lib -ltsp -ldl -lsocket -lnsl -lposix4

All of the Solaris 8 support for wackamole was added in the CVS version
and tested on Solaris 8 Intel. The Intel branch of Solaris has an
identical userland interface/API for all system stuff. So, it should
work fine on Solaris 8 Sparc.

I don't believe that the release version has any hope of running on
Solaris 8... The OS specific stuff simply isn't finished there.

This means that you will need to explicitly specify which addresses to
arp spoof to. This is the way wackamole release version is anyway, but
here you can specify which interface and entire subnets. That code for
Solaris is unfinished. I will try to get to it soon.

I have code for this... I just need an hour or so on a Solaris box to
clean that up.

Yup. The next release will not, but the CVS version will. flex and
bison will be run before the release source is packaged... So you won't
need them.

Can you mail be the compile error please?

Thanks.. I just added that to the autoconf stuff.

The first is a quick fix on my end. I need to put that code into CVS.
The second is a quick fix, if you do'nt want a real arp cache. Just
stub the function out :-) [.I just committed a tub to CVS -- I'll have
it do the right thing on Soalris as soon as I figure out how]

Sorry for all the trouble (you too Min). I am running this stuff on
FreeBSD actively, so that always gets the first bit of attention :-)

Yair,

Thanks for your response. Now it's time you
toot your honk a little bit. Where can I
find some of the current users of Spread
and Wackamole? I thought I came across
something earlier, but don't remember where.

Thanks,

Hey,

If someone is even able to spare a solaris 8 box, I am sure
we will be happy to find a power outlet for it in the computer room
of the lab :)

Cheers,

:) Yair.

Jason,

I got pretty much similar problem in my Solaris 8 installation. I am
glad to see that you can offer two Solaris boxes for troubleshooting. Has
the offer been taken by Wackamole developers? I think quite a few of us
are anxiously looking forward to be able to run spread/wackamole/backhand
on Solaris.

Thanks!

Alex

As we indicated a few weeks ago:
If someone provides access to the environment we can have a look.

I am sure Aashima can call you sometime to set access. Bare in mind
these programs really play with the IP addresses, so make sure your
network will not get crazy because of that (our does sometimes when we
debug).
