Hi, lib/sha2.c has: #ifdef HAVE_STDINT_H #include <stdint.h> #else typedef unsigned char uint8_t; typedef unsigned int uint32_t; typedef unsigned long long uint64_t; #endif while there is no previous attempt to detect and set HAVE_STDINT_H anywhere, which means the else part will fire, and cause: sha2.c:59: error: conflicting types for '__uint64_t' /usr/include/machine/int_types.h:54: error: previous declaration of '__uint64_t' was here due to string.h already pulling in a conflicting definition on NetBSD.

Need Help Configuring BBWin on DMZ
by wiskbroom＠hotmail.com 08 Feb '10

08 Feb '10

Hello; I am trying to get BBWin installed on a box within a DMZ, my intention is to set this up so that the server pulls the data from the client. My BBWin.cfg has this: <setting name="bbdisplay" value="127.0.0.1:1984" />   <setting name="usepager" value="false" /> <setting name="bbpager" value="127.0.0.1" /> <setting name="pagerlevels" value="red yellow" /> -- I've tried various settings to the above, none allow me to telnet to localhost onto port 1984. There is no firewall, yet, preventing me from doing so. The windows agent has been started. Somewhat related, although not yet at this step, are my servers settings, please see below. My bb-hosts file will contain: 192.168.1.10 my-hostname # nconn hobbitfetch pulldata The host is not-pingable, but I do allow outbound port 1984 to it. The only other changes I am adding are to hobbitlaunch.cfg on my server: [hobbitfetch] # DISABLED <-- Comment it ENVFILE /hobbit/server/etc/hobbitserver.cfg CMD $BBHOME/bin/hobbitfetch --server=172.10.1.10 --no-daemon --pidfile=$BBSERVERLOGS/hobbitfetch.pid <-- replace the IP by your Hobbit server one LOGFILE $BBSERVERLOGS/hobbitfetch.log FYI: My Xymon servers IP is 172.10.1.10 Thank you, .vadim

Alerts - HOSTS matching regular expressions.
by kii.noda＠gmail.com 07 Feb '10

07 Feb '10

Hi everyone, As you may have already been aware by now, we're here to stay. :) Here's one interesting problem (and maybe simple) for you: We've seen that "HOST=%^asd$" matches both hosts named "asd" and "asdf", not respecting the "$" at the end. Can you guys please confirm that regex matching for "HOST=" does not care about the "$" sign? For those that need some expanded case-study (all others can now stop), here's the story behind: we are managing various servers of ours and our customers. Due to the fact that we do not control DNS entries for all these machines we have come up with a naming scheme like this: --- cut here --- junkyard-starbox # clientID=junkyard, starbox=actual machine junkyard-starbox-v_trash # v_trash=vserver named trash running on starbox junkyard-starbox-v_trashcan # v_trashcan=vserver named trashcan running on starbox junkyard-starbox-x_dustbin # x_dustbin=xen server running on starbox --- and here --- We need to send these "special" alerts: * ONLY cto at junkyard.tld for events on junkyard-starbox-v_trash * ONLY ceo at junkyard.tld for events on junkyard-starbox-x_dustbin Also, we need to send these alerts for all other hosts & events: * stars at sysadmins.tld for purple, yellow & red w/ REPEAT=60 * cto at sysadmins.tld for red w/ DURATION>30 and REPEAT=60 * cto at sysadmins.tld for yellow&purple w/ DURATION>60 and REPEAT=60 Exercising our brain muscles we came up with these: --- cut here --- #alert CTO for v_trash HOST=junkyard-starbox-v_trash MAIL=cto at junkyard.tld #alert CEO for x_dustbin HOST=junkyard-starbox-x_dustbin MAIL=ceo at junkyard.tld #stop alerting for the private boxes above HOST=* IGNORE HOST=%^junkyard-starbox-(v_trash|x_dustbin)$ HOST=* COLOR=purple,yellow MAIL=stars at sysadmins.tld REPEAT=60 RECOVERED NOTICE MAIL=cto at sysadmins.tld DURATION>60 REPEAT=60 RECOVERED NOTICE HOST=* COLOR=red MAIL=stars at sysadmins.tld REPEAT=10 RECOVERED NOTICE MAIL=cto at sysadmins.tld DURATION>30 REPEAT=60 RECOVERED NOTICE --- and here --- However, even with the "$" at the end of our regex we are no longer receiving any alerts for v_trashcan because the regex wrongly matches on the "IGNORE HOST=" line. We could use 2 lines to match each host on its own line but that's not the point of this exercise. So, can anyone confirm our finding? -- kN

purple status for one server and hobbitfetch?
by cade.robinson＠gmail.com 05 Feb '10

05 Feb '10

I have one server that keeps coming up purple and I can't get rid of it. The ping it working and it is alerting when it goes red but it just stays purple all the time. When I look at the conn page it shows: Status message received from hobbitd rather than Status message received from 172.16.225.176 Also as a test someone setup hobbit on this machine at one time to see how hobbit worked without screwing up the current real hobbit server. Since then the machine in question had hobbit server removed and is now just a client. I have tried to drop the conn column and also the whole server and also removed all files with the server name in hist and histlogs. It still comes back purple and is the only one. I can't find any file in server/etc that has its name or IP. Any thoughts on why? Also we have clients in a DMZ we want monitored and are using hobbitfetch for that. Once I fixed the core dumping of hobbitfetch and it is staying up the status is still purple. Anyone know how to get that not purple? Is it not reporting a status to something? I was trying to figure out how status of the daemons was determined and haven't found it yet but my guess is that hobbitfetch isn't reporting something it should. Thanks Cade

Unable to create Availablity Report spreadsheet.
by TRBrand＠cvs.com 05 Feb '10

05 Feb '10

Hi all... I'm having a problem generating a 'spreadsheet' availability report (Reports | Availability Report ) with the Xymon 4.3.0-0.beta2 server and could use some help/suggestions as to where to look next. These reports were working as late as two weeks ago; I can't think of anything that I've changed in the environment that should affect the report generation. bbgen for Hobbit version 4.3.0-0.beta2 Statistics: Hosts : 3015 All other reports appear to be working fine. If I select the 'Generate Report' button, my report gets created and displays and the files are created in the www/rep/ directory When selecting 'Generate Spreadsheet', the result is: Generating report for the period: Jan 27 2010 - Jan 27 2010 (nongr) --bbrep-7740-126471984 Content-type: text/html Could not generate report. Check that the /home/xymon/server/www/rep/ directory has permissions '-rwxrwxr-x' (775) and that is is set to group 8 I have checked the ownership and permissions of the directory tree and all seems ok... # ls -l /home lrwxrwxrwx 1 root root 11 Jul 22 2008 /home -> /cvsrx/home/ # l -d /cvsrx lrwxrwxrwx 1 root root 15 Jan 19 10:23 /cvsrx -> /data/cvsrx_dev/ # l -d /cvsrx/home/ drwxr-xr-x 32 root root 4096 Dec 7 11:25 /cvsrx/home// # l -d /cvsrx/home drwxr-xr-x 32 root root 4096 Dec 7 11:25 /cvsrx/home/ # l -d /cvsrx/home/xymon/ drwxr-xr-x 11 xymon hobbit 4096 Jan 8 14:36 /cvsrx/home/xymon// # l -d /cvsrx/home/xymon/server/ drwxr-xr-x 9 xymon hobbit 4096 Dec 7 11:40 /cvsrx/home/xymon/server// # l -d /cvsrx/home/xymon/server/www/ drwxr-x--- 16 xymon www 4096 Jan 28 18:12 /cvsrx/home/xymon/server/www// # l -d /cvsrx/home/xymon/server/www/rep/ drwxrwx--x 8 xymon www 4096 Jan 28 18:10 /cvsrx/home/xymon/server/www/rep// # l /cvsrx/home/xymon/server/www/rep/ total 28 drwxr-xr-x 7 wwwrun www 4096 Jan 28 18:01 6916-1264719548/ drwxr-xr-x 7 wwwrun www 4096 Jan 28 18:03 7703-1264719824/ -rw-r--r-- 1 wwwrun www 2109 Jan 28 18:04 avail-s09trbrxs-memory-1264719841-7737.txt I added '--debug' to bb-rep.cgi: exec /home/xymon/server/bin/bb-rep.cgi $CGI_REP_OPTS $BBGENREPOPTS --debug >/tmp/bbrep.debug 2>&1 and got a large output file.

Nesting PAGE= into Macro Possible in hobbit-alerts.cfg?
by wiskbroom＠hotmail.com 05 Feb '10

05 Feb '10

Hello; I am trying to define a group of hosts for alerting purposes and am unable to see successful results when I run bbcmd hobbitd_alert --test CLIENT-HOSTNAME cpu CLIENT-HOSTNAME does appear as being a member of the same page/subpage I've declared in my alerts file. Here is what ~bbcmd hobbitd_alert --test CLIENT-HOSTNAME cpu gives me: 00006992 2010-02-05 10:17:09 send_alert CLIENT-HOSTNAME:cpu state Paging 00006992 2010-02-05 10:17:09 Matching host:service:page 'CLIENT-HOSTNAME:cpu:myservers/mywinboxes/mywintelsqlservers' against rule line 194 00006992 2010-02-05 10:17:09 Failed 'HOST=$WINDOWSHOSTS' (hostname not in include list) My hobbit-alerts.cfg has this: $WINDOWSHOSTS=PAGE=myservers/mywinboxes/mywintelsqlservers Is this syntax right? Am I allowed to declare a PAGE within a MACRO like this? Any suggestions into how best to define what I've declared as either a page, and.or subpage, in my bb-hosts would be greatly appreciated. Thank you in advance, .vadim

hobbitfetch core dump fix
by cade.robinson＠gmail.com 05 Feb '10

05 Feb '10

I was having issues with hobbitfetch core dumping. I finally figured out the issue. In the "grabdata" function there is: int n; char buf[8192]; /* Read data from a peer connection (client or server) */ n = read(conn->sockfd, buf, sizeof(buf)); ... else if (n > 0) { ... buf[n] = '\0'; ... If 8192 bytes are read then "n" is 8192. There is no element 8192 in buf. buf is 0-8191.

client tests on some machines
by werner＠maiers.de 04 Feb '10

04 Feb '10

Hi, I'm migrating a BB setup to hobbit. I have a client test, that is run only on some machines. how can I do that with hobbit? ==> I have all clients running the same client software with binary distribution, all clients have a [extensions] in clientlaunch.cfg where ONE external shellscript is startet (that script calls the different local tests I have). All those external scripts are distributed via binary update. in BB I had the bb-hosts distributed onto the clients and the scripts were parsing that file to check if they had to do something. a solution would be to have a bb-hosts in the ext/-Directory also, that would be distributed via binary update, and the scripts would check against that bb-hosts file. is there any other more flexible way? is it possible for the clients to fetch the content of the serverside bb-hosts or hobbit-client.cfg? any pointers to the right documentation welcome. regards Werner. -- Dipl.-Ing.
