Hello all,
Looks like I found the favorite crash in hobbit. I am running 4.1.1 and just "upgraded" from bb. I followed the bb->hobbit instructions to the t and everything appears to be working except for this test ( and the tests associated with it ). I tried commenting out everything but one line in my bb-hosts, but it just seems like if I have more than one test it croaks with a seg fault.
Here:
Environment BBLOCATION='' Environment CONNTEST='TRUE' Environment IPTEST_2_CLEAR_ON_FAILED_CONN='TRUE'
Service list dump ./bbcmd bbtest-net --debug --ping --checkresponse (skip few dozen lines) 2005-09-16 11:11:20 Got DNS result for host server : <ip> 2005-09-16 11:11:20 Adding tcp test IP=<ip>, port=143, service=imap, silent=0 Aborted (core dumped)
(gdb) file bbtest-net Reading symbols from bbtest-net...done. unknown option `--debug' (gdb) run Starting program: /home/monitor/server/bin/bbtest-net
Program received signal SIGSEGV, Segmentation fault. 0x08050571 in add_tcp_test (ip=0x809806c "24.220.8.53", port=143, service=0xbffff9fc "imap", sslopt=0x0, silent=0, reqmsg=0x0, priv=0x0, datacallback=0, finalcallback=0) at contest.c:182 182 newtest->sendtxt = (reqmsg ? reqmsg : newtest->svcinfo->sendtxt);
It dies on the first host it loads the tests for. Here is my first host:
page mail Mail servers group-compress <ip> mailserver # smtp pop3 imap ssh !dns !ftp
Anyone have any hints on what to do? What happens on this line: newtest->sendtxt = (reqmsg ? reqmsg : newtest->svcinfo->sendtxt); ? If I knew C, I'd contribute:)
Thanks
Dan
Here's an update.
If I only have one server in the bb-hosts bbtest-net doesn't fail with any of these services:
<ip> hostname # ntp dns conn ldap ssh2 ssh1 bbnet pop rsync bbd ftps telnets smtps pop3s imaps nntps clamd ldaps vnc
If I use *any* of the other services, that is:
ftp ssh telnet smtp imap imap2 imap3 imap4
I get an immediate:
2005-09-16 14:33:12 Adding tcp test IP=<ip>, port=143, service=imap, silent=0 Aborted (core dumped)
This might help too:

Whoa! Why's it looking for 0x4? Is that a bug?
Thanks

Something's up with your service definitions. "newtest->svcinfo" is obviously bogus, which is why you get the segfault when it tries to reference newtest->svcinfo->sendtxt.
Is "imap" listed if you run "bbtest-net --services" ? It should read
Name : imap Sendtext: ABC123 LOGOUT\r\n Sendlen : 15 Exp.text: * OK Exp.len : 4 Exp.ofs : 0 Flags : 1 Port : 143
Also, check the ~hobbit/server/etc/bb-services file - is it readable by your hobbit users ? What's the content of it ? You can compare it with the one in the hobbit-4.1.1 sources (in the bbnet/ direcory).

Heh,
I guess we know what happens know if someone were to accidently use the bb-services file that comes from bb-gen instead of the one from hobbit:) That was my problem, I copied the real one (back?) over and it's working just fine.
Thanks Henrik!
