traffic map / configuring vlan

I Routers will only show up in the traffic map once the links between them have been discovered. This process should be automatic with no extra configuration required as long as the NAV background processes are running (the getDeviceData process does the actual data collection). If you go to the 'Report' tool and select the 'Prefix' report, are your VLANs listed? Links between routers should be of nettype 'link' and the number of router ports ('antgw' column) should be 2. -- Kristian

SV: Re: [Nav-users] Comments on the installation-guide nav 3 on SuSELinux Enterprise Server 9
by peder.sefland＠hivolda.no 29 Jun '05

29 Jun '05

The package gpg-pubkey-b481ca4d listed in the installation-guide is not part of the SLES9. I think the package that is ment is the "suse-build-key". But my problem now is that I have a nav3rc1 running on SLES, and everything "seems" to be running except web-interface and Alertengine. I have used the SuSE rpm package. And is trying to find whats wrong with the apache-config. I have tried to look at the http://svn.nav.ntnu.no/nav/navme/trunk/doc/apache/httpd2.conf.example But the apache-structer is totaly different from my debian-nav3-beta10 installation.

by roger.aas＠hsh.no 28 Jun '05

28 Jun '05

I have added a step-by-step installation guide for NAV3 RC1 on Red Hat Enterprise Linux 4 on the MetaNAV Wiki. You can find it here: http://metanav.ntnu.no/moin.cgi/InstallingOnRHEL4 Please give me feedback when you find errors or omissions so I can fix them. Or if you just want to comment it... :-) I hope this can be of help for someone. Regards, Roger -- Roger Aas Stord/Haugesund College

[Nav-users] Software versions not retrieved for most routers and switches
by roger.aas＠hsh.no 27 Jun '05

27 Jun '05

In NAV2 I used the "Rapportgenerator" (Report generator) to get a listing of the software versions that was on my routers and switches. It was only the Cisco 1900 series switches that did not get listed with a software version number in NAV2. I also missed the sw version number data for AP's, but it seemed like there were no support for that in NAV2. This report was very valuable since I could get a listing of which boxes needed to be upgraded if there were reported some security advisory for a specific software version. But in NAV3 most of my switches is listed without software version. It is only some of the included types that lists up version numbers. This is the wsc5000, wsc5505 and the catalyst297024TS. One type that is included, cat4506, does not report the sw version (but that one also has a supervisor 5 card, not a "sup4" that is in the description). But I have many types of 2950, a 2912 and a 4510r that does not list the sw version. The "Wireless" report in NAV3 have a coloumn for Software but all my C1100's and C1200's and two Avaya ROR-II AP's does not report software version either. Is this a known problem? - Roger -- Roger Aas Stord/Haugesund College

> /BUILD FAILED > /root/nav-3.0_rc1/src/SimpleSnmp/build.xml:30: Compile failed; see the > compiler error output for details./ Although you didn't include the actual error message I am guessing the compile failed because you are missing the Java SNMP package.

Postgres : unexpected EOF on client connection
by roar.pettersen＠it.uib.no 10 Jun '05

Hello ! I've installed NAV 3.0-rc1, and i have a postgres problem with too many postgres processes, eg : postmaster: navwrite manage 127.0.0.1 idle (postgres) postmaster: navwrite manage 127.0.0.1 idle (postgres) postmaster: navwrite navprofiles 127.0.0.1 idle (postgres) postmaster: navwrite manage 127.0.0.1 idle (postgres) postmaster: navwrite navprofiles 127.0.0.1 idle (postgres) postmaster: navwrite manage 127.0.0.1 idle (postgres) postmaster: navwrite navprofiles 127.0.0.1 idle (postgres) When i have more than 30-35 processes, then NAV stops working, and i have to stop and start the database. Looking into my postgres log file i see this : postgres[67232]: LOG: unexpected EOF on client connection postgres[67233]: LOG: unexpected EOF on client connection postgres[67234]: LOG: unexpected EOF on client connection postgres[67235]: LOG: unexpected EOF on client connection postgres[67236]: LOG: unexpected EOF on client connection postgres[67237]: LOG: unexpected EOF on client connection Anybody have a clue ? -- Med vennlig hilsen / Regards; Roar Pettersen Universitetet i Bergen - The University of Bergen Nygardsgt. 5 - N-5020 BERGEN - Norway Tlf: +47 55 58 40 55 VIP: 81503 fax: +47 55 58 40 70 roar.pettersen(a)it.uib.no - IT-Avd, UiB - http://www.uib.no >From kreide at gmail.com Fri Jun 10 13:28:37 2005 From: kreide at gmail.com (Kristian Eide) Date: Fri Jun 10 12:28:53 2005 Subject: [Nav-users] Postgres : unexpected EOF on client connection In-Reply-To: <Pine.GSO.4.61.0506101108230.4532(a)alf.uib.no> References: <Pine.GSO.4.61.0506101108230.4532(a)alf.uib.no> Message-ID: <200506101228.41534.kreide(a)gmail.com> > I've installed NAV 3.0-rc1, and i have a postgres > problem with too many postgres processes, eg : NAV does use quite a few database connections (on our production machine here I see 17 active now) as each subsystem needs one or more connections (heavily threaded subsystems may use more than one connection) and each http process will also require a connection. > When i have more than 30-35 processes, then NAV stops > working, and i have to stop and start the database. This seems like too many though, unless you have apache configured to spawn a high numer of processes. > postgres[67237]: LOG: unexpected EOF on client connection Yes, we get these as well. The culprit seems to be alertengine, probably it is not closing its database collections properly (and this also seems to indicate it is opening a new database connection each time it polls the alertq, which is highly inefficient). Andreas, can you take a look at this? I also get a few of these in the log when starting alertengine: 2005-06-10 12:20:52 ERROR: syntax error at end of input at character 90 -- Kristian
