Well, upon reading the truss output of "nav start getDeviceData", it seems that the "su" command is the one that hangs after the chdir command. Can you successfully execute "su - navcron" as root? Does the navcron user have a valid login shell? > What is the difference between 'nav start ....' and executing the process > directly, ie: > cd etc/init.d > ./getDeviceData start > > "nav start ..." fails and "./getDeviceData start" succeeds? I think the > inherent difference may help us to understand what is happening and why the > failure. Or at least may help me to locate more pertinent data. There's no difference, really. The nav command is a convenience tool to do all the starting and stopping in one go (plus the added crontab manipulation). It still calls the etc/init.d scripts in the end. Are you running both commands as root? >> Besides, you say that "nav start alertengine" seems to stall, and this >> command will not modify the crontab, since alertengine isn't a cronjob >> but a daemon.

I su'd to navcron, just to verify and this > command is denied (as I expected). Wait, are you saying that "su - navcron" fails? That would be a reasonable cause for your problem. Several of the init scripts are designed to be run as root, and use su to drop privileges to navcron before executing processes that cannot drop privileges by themselves (such as java). As I mentioned in less detail above, the navcron user must have a valid login shell for the su'ing to work. > there is a Python class for crontab but nothing that defines command line > arguments (not familiar with python). Crontab commands are hardcoded on lines 243 and 261 in startstop.py. The nav script requires root access to run properly (and will give a warning/error if executed by anyone but root). > I've also included the strace output - as it sounded like you are more > familiar with strace - may help to locate the issue. Thanks, although I found the complete truss (with forks) output more helpful this time around :-) -- mvh Morten Brekkevold UNINETT

Services

Good Evenin', Being new to nav..... Installation is on FreeBSD v6.x. Performed initial install from the 'ports' collection. After following instructions on basic configuration (included setup of Postgres, setting up a couple devices, room, location, etc.) it appears that some services still aren't starting: $$> nav start Starting: cricket iptrace logengine mactrace maintengine networkDiscovery pping smsd thresholdMon Failed: alertengine eventengine getDeviceData servicemon I've already done some research and had to hand-tool some .py files as there were errors for "import sre as re" and python stated that it was deprecated, ie: it should be "import re" (sre is now re) I'm not seeing any log data (even with debug=6 in nav.conf) for the failed services. Does anyone have information that may lead to this being more successful? BTW - we utilize Apache 2.x with AD authentication for internal resources. I've seen some errors with python and the web pages as well - is there an expectation that it would be Apache 1.x instead? Here are some specifics: OS: FreeBSD v6.x (Microsoft/BSD shop) Java: Diablo JDK-1.5.0 Tomcat: 6.0.14 Cricket: 1.0.5_4 nav: 3.2.2 Python: 2.5.2 Apache 2.2.8 ant: 1.7.0 Thanks!

Superb. I have a 7.x machine that I'll give this a run on today.

Using telnet access to the switch I can see the ARP table (mapping > MAC-IP), so I thought that NAV uses this information for mapping IP->MAC. The switch's ARP cache will only contain entries for addresses that are communicating directly with the switch on layer 3 (i.e. your workstation telnetting to the switch CLI). This information is mostly useless - NAV will only collect ARP caches from routers, which provides us with every active, routed IP address in your network (assuming you're using NAV to monitor all the routers in your network). > So, I need at least one router to search IP->MAC, and once I have the MAC I can > search is Switch/Module/Interface location. Correct :-) -- mvh Morten Brekkevold UNINETT P.S. I'm assuming you accidentally forgot to reply-to-all, so I'm Cc'ing the nav-users list.

Problem with NAV 3.3.3 Machine Tracker
by Helder Vieira Mendes 17 Apr '08

17 Apr '08

Hello, Helder Mendes from ISEP. I am using NAV 3.3.3 in Debian 4.0, but the Machine Tracker is not working well because if I do MAC Search NAV return´s the IP in the correct door / switch (by ARP table search), but if I search by IP does not return the MAC, does not return any thing ... The ARP tables are the same it should work ... Thanks for helpping. Helder Mendes, ISEP / IPP

Migration from Subversion to Mercurial
by Morten Brekkevold 09 Apr '08

09 Apr '08

Hello everyone, Those of you who subscribe to the nav-dev list will already know that last week we migrated from Subversion to Mercurial as our version control software. Each official development branch now has its own repository at http://metanav.uninett.no/hg/ . The development branch named "default" represents what we called trunk in Subversion. If you have been using Subversion to get the latest development version, you should now use Mercurial, and clone the repository at http://metanav.uninett.no/hg/default/ . For more information about Mercurial, please see http://www.selenic.com/mercurial/ . Those of you who monitor NAV commit logs by subscribing to the nav-commit mailing list should now subscribe to the individual RSS or Atom feeds of the branch repositories at http://metanav.uninett.no/hg/ - the nav-commit mailing list will soon be taken offline. Have a great day! -- mvh Morten Brekkevold UNINETT
