bbtest-net core dumps when reading bb-services 🔗 link

Hi,

I'm running the 4.1.2.p1-1 .deb-package on a Debian Sarge box. After not getting any test results I realized that the bbtest-net daemon does not even start, but directly segfaults after startup. After playing around with strace I figured out that it has to do with the service definitions. After I moved /etc/hobbit/bb-services away, it starts perfectly, just complaining that it has to use internal defaults.

Another uncorrect behaviour (I guess) with the bb-services file from the package in its default location:

hobbit at debianbox:~$  bbtest-net --services --debug 2>&1
Command: bbtest-net '--services' '--debug'
Environment BBLOCATION=''
Environment CONNTEST='TRUE'
Environment IPTEST_2_CLEAR_ON_FAILED_CONN='TRUE'

Service list dump

BBNETSVCS set to : smtp telnet ftp pop pop3 pop-3 ssh imap ssh1 ssh2 imap2 imap3 imap4 pop2 pop-2 nntp
Service list dump

hobbit at debianbox:~$

I tried even a very minimalistic bb-services file with just the smtp service definition from the bb-services.5 man-page. That also leads to a segfault.

Is this a known problem for the Debian package? Could this also have to do with our bb-hosts file that I copied from a BB 1.9c server?

Andreas Dembach

So the million dollar question is: What's in your bb-services file ?

No, I use the Debian packages myself and dont have this problem.
I suspect there is something different in your bb-services file
(it's flagged as a configuration file, so dpkg will not overwrite
it with a default file if you have changed it locally). If you
have a bb-services.dpkg-dist file, is it any different ?

Well, as I said, nothing too complex I guess, since it's the default file 
from the package. And even with the following file, it segfaults:

No, it's a fresh install.

That's not from the debian package, that is an old-style bbgen version
of the bb-services file.

Try doing

   mkdir tmpdir
   dpkg -x hobbit_4.1.2p1-1_i386.deb ./tmpdir/

This unpacks the .deb-file into the tmpdir directory. In
tmpdir/etc/hobbit/bb-services you'll find the real file - I am sure 
that is different from what you have.

Specifically, the "service smtp" line is now "[smtp]".


Henrik

Yes, that works.

I took the section below from the bb-services man page. Seems to be 
outdated, then.

Thanks a lot,
Andreas

This line I thought would do it, but the comment says that it isn't used by
Hobbit.

hobbitserver.cfg:PAGELEVELS="red purple"        # Status colors that trigger
an alert. Used by 'bb' talking to bbd, not by Hobbit.

I want to turn pages for purple statuses off.

Thanks

Check you MANPATH setting. I'd guess you have some duplicate man-pages
found in both /usr/local/man/ and /usr/share/man/ 
(e.g. the man5/bb-services.5 file).

The man-page from the debian package doesn't have that section you
copied.

Yes, true. There is still the old BigBrother intallation on this server, 
which also had the bbnet/bbgen tools.

Andreas

You need to look at these settings in hobbitserver.cfg:

ALERTCOLORS="red,yellow,purple"                 # Colors that may trigger an alert message
OKCOLORS="green,blue,clear"                     # Colors that may trigger a recovery message

You can just remove the "purple" from the ALERTCOLORS setting.

One of my http servers went down and the conn test went red and http and content went blue, this was fine
with me and makes sense.  When the server came up the conn test went green ; now the http remained blue
but should  have been red ; http wasn't  brought up for over an hour.!  This was unexpected behavior  and
misleading because my web servers page was a green dot (correct blue should not propagate up) but
when you click on it it show that one web server  with green conn but blue http/content.
Im using 12/28 snapshot on hpux 11.0.

"blue" only happens if you have something like planned downtime. http should go "clear" when the entire server goes down and conn is red.
This also matches your observation that http remained "blue" until it
was brought up again.


Henrik

Happen again this week end.  Another web server was taken down and brought up;  HTTP  was not started
(we don't start it at boot time so that was right)  and I found the server green and http blue.

Well, did you check if there's a DOWNTIME setting for this host ?

I'd like to see the bb-hosts entry for it. If you run network tests
from a separate server, check the bb-hosts file on both the Hobbit
and the network test server.


Henrik

Long ago I never got a response on this.  Can anyone shed any light on it
now possibly?

I do not want to receive any pages when a box goes purple for whatever
reason.

Thanks in advance
