using samples/C++/client/brutus

Hi Rüdiger,

Post by RÃ¼diger Meier
Finally I got time to try the brutus thing again!
We installed brutus server 1.0 on a fresh WinXp, then I wanted to test the
sample client first on openSuse 10.2 64bit.

Its a loooong time since I tried the C++ client myself ;-) I usually
test with the C client due to the slow IDL compiler from TAO...

I checked out
http://svn.42tools.net/repos/brutus-idl/trunk/
After installing ace-tao (rebuilded from ace-tao-5.6.5-6.fc9.src.rpm)
$ cd brutus-idl/trunk/samples
$ make stubs
$ make
After that I got a binary
samples/C++/client/brutus_client
$ ./brutus_client
[...]
Parsing configuration file..

Getting BrutusLogOn server object key.. OK, "BRUTUS_LOGON"

.......
Any ideas?

Not getting the root POA is an indication of API change in TAO since I
looked at the C++ client myself. I can take a look at it tomorrow.
I'll fix the build problems you mention below too.

Is it correct to use my usual windows logon for MAPI_PROFILE or what does it
mean?

MAPI_PROFILE is simply the name of the file on the server that holds
your MAPI profile. You can name it whatever you like.

Best regards and thanks,
jules

I could solve that by editing "samples/C++/init_orb/init_orb.cpp"
{
char server_port_str[6] = { '\0' };
snprintf(server_port_str, 6, "%hu", server_port);
init_ref_arg = append_string(&init_ref_arg,
server_port_str);
}
Maybe you want to fix this in svn too.

Ok, C client was more difficult to compile here but now I got it.

The C++ sample is now building again and it will give you a root POA.

The test client can't reach your Brutus server at all. It simply tries
the read the version from the server. This operation is fully capable
of succeeding without Lorica as long as the server is up and that it
is routable from the client.

Hm, I watched brutus_client with wireschark and noticed that it doesnt
sent any packet to brutus server.
I tried both resolvable name and IP for BRUTUS_SERVER in client.conf.

Brutus server is pingable and port 2003 reachable.

Is this using some kind of windows service or does it talk to brutus
server here?

So "gabrutus" is routable from the client?

It talks to the Brutus server. The nice thing about GetVersion() is
that it doesn't use any callback referecne so the client need not be
reachable from the server.

yep
$ netcat -z gabrutus 2003 && echo "reachable"
reachable

And I can see netcat's action with tcpdump:
$ tcpdump -i eth0 host gabrutus
15:06:57.889445 arp who-has gabrutus.ga.local tell quant.ga.local
15:06:57.890393 arp reply gabrutus.ga.local is-at 00:0c:29:9e:a1:c3 (oui
Unknown)
15:06:57.890408 IP quant.ga.local.48551 > gabrutus.ga.local.2003: S
2838194289:2838194289(0) win 5840 <mss 1460,sackOK,timestamp 1343457921
0,nop,wscale 7>
[......]

But if I start brutus_client then tcpdump shows nothing, so what is
brutus_client actually trying to do?

Could this be some kind of IPv6 issue? Because client its telling me
"IPv4 or IPv6 is supported in ORBit2.."

It is establishing a connection with the server. You can see it all
here:

http://trac.42tools.net/brutus-idl/browser/trunk/samples/C/client/main.c

Could you please try to use the FQDN of the server instead?

IPv[4.6] can be disabled in ORBit2 so that is just a check to make
sure they're not.

I read somewhere that if the mDNS package is installed and used, it
'might' be filtering out the '.local' domain...
