[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

Postgres : unexpected EOF on client connection

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.

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

NAV workshop

Hi, We are planning a NAV workshop here in Trondheim on monday June 13. As we suspect this will only attract a Norwegian audience, the following is in Norwegian. (If I am wrong, please give me a hint): Vi har laget wiki-sider som beskriver programmet. Programmet er p? mandag 13. juni fra kl 15->. [1] S? alle NAVere - meld dere p? (en del av dere er forh?ndp?meldt)! Gj?r oppmerksom p? at vi m? sette en grense oppad. I utagnspunktet 50 stk. Vi vil kanskje ogs? m?tte gj?re en begrensning med antall fra hver enkelt institusjon om n?dvendig. Les mer p?: * http://metanav.ntnu.no/moin.cgi/NAVFagseminar Jeg kan ogs? r?pe at vi i neste uke kommer med en NAV 3.0 release candidate. F?lg med. [1] Det er lagt til dette tidspunktet bl.a. fordi det korresponderer med et gigacampus arbeidsgruppem?te som er dagen etter (dette m?tet diskuterer overv?kning mer generelt og deltagere er de som inng?r i arbeidsgruppen, disse er forh?ndsp?meldt NAV fagseminaret). -- mvh - Vidar >From magnus at ntnu.no Wed Jun 1 17:01:33 2005 From: magnus at ntnu.no (Magnus Nordseth) Date: Wed Jun 1 16:01:35 2005 Subject: [Nav-users] Another questions about vlanPlot In-Reply-To: <s29dd972.064(a)HVO-3.hivolda.no> References: <s29dd972.064(a)HVO-3.hivolda.no> Message-ID: <20050601140133.GH17281(a)stud.ntnu.no> Peder Magne Sefland: > I'm running nav3 on debian-sarge and found the file under > > locate vlanPlot.py > /usr/lib/python2.3/site-packages/nav/web/pyproxy/vlanPlot.py > /usr/lib/python2.3/site-packages/nav/web/pyproxy/vlanPlot.pyc > /usr/lib/python2.3/site-packages/nav/web/pyproxy/vlanPlot.pyo > > I made a copy of the original file and tried to do some changes here, > but no success. > How do I manually set the hostname or ip-address? It assumes you are running tomcat, the cricket front end and the NAV frontend on the same server. This could be a bit inflexible for some installations. The hostname is defined on the line server = req.server.server_hostname which extracts the hostname from the current http request. You can modify this line so it suits your needs. However, this hostname is used for vPServerURL, lastURL, cricketURL and netflowURL. If you want different hostnames for only some of them, you have to modify how the params are defined. I probably should move all this out to a config file some day. Also note that you have to restart apache after you have made your changes to ensure mod_python reloads the new file.

You are quite right; it seems it was removed by another developer. The server name is now automatically set as the same URL used for accessing vlanPlot itself, however, it can be changed manually by editing: /usr/local/nav/apache/webroot/vlanPlot/vlanPlot.py Look for 'vPServerURL' and 'cricketURL'. -- Kristian >From kreide at gmail.com Wed Jun 1 16:58:09 2005 From: kreide at gmail.com (Kristian Eide) Date: Wed Jun 1 15:58:15 2005 Subject: [Nav-users] Another questions about vlanPlot In-Reply-To: <s29dd972.063(a)HVO-3.hivolda.no> References: <s29dd972.063(a)HVO-3.hivolda.no> Message-ID: <b4c110fd050601065861b1fc57(a)mail.gmail.com> > /usr/lib/python2.3/site-packages/nav/web/pyproxy/vlanPlot.py > /usr/lib/python2.3/site-packages/nav/web/pyproxy/vlanPlot.pyc > /usr/lib/python2.3/site-packages/nav/web/pyproxy/vlanPlot.pyo I see on our production server we have: /usr/local/nav/lib/python/nav/web/pyproxy/vlanPlot.py You can probably edit the file in site-packages as well.
