Centos 5 and NAV 3.2.2

Hi,
first of all i'm trying to run NAV 3.2.2 on a Centos 5 and i know it's not 
supported, but with really liitle tweaking the system seem to be up and 
running, despite the problem i've always had with my HP9304m that i've 
already posted about (answer pending...).

I get some errors from: 

Cron <navcron <at> nav> $BINDIR/getBoksMacs.sh $NUM_THREADS

the body of the message is at the end of this msg, there's something i can do 
to fix it or the set of libs that comes with Centos5 is too much different to 
let NAV work as it is?

Thanks for reading and my best regards, Marco barbieri.

Re: Problem with NAV 3.2.2 and Hp 9304M - WRONG DATA - SORRY

Given the OID compatibility report you sent, NAV should be able to detect the
ports on this routing switch; the ports are detected using standard mibs.  Yet
 you say that _no_ ports are detected?  If that is so, I would like to see
what  getDeviceData.log says when it collects from this device.

When it comes to modules, I must admit that NAV's support for HP equipment is
lacking in several respects.  The HP support was written and tested using the
equipment that was available at the Norwegian University of Science and
Technology at the time, and these were all HP SwitchStacks.  Consequently, NAV
only recognizes virtual stacking in HP equipment, and cannot at all recognize
modules in your HP chassis.

It is in our plans to implement more generic module support through
interpreting the ENTITY-MIB.  I'm guessing your HP9304M presents a fairly
correct view of its physical contents through its entPhysicalTable?  Since I
have no access to a 9304M myself, but am planning to code the ENTITY-MIB
support, I would greatly appreciate it if you could provide me with the output
of this table from your device; running this command on your NAV server should
do it:

  snmptable -Ci -Cb -v2c -c <community> <ip> entPhysicalTable

That depends on what you mean by "supported" :)  We do not guaruantee support
to anyone, but you should be able to have NAV up and run on any Linux distro.
 The most common obstacle seems to be when some software that NAV depends on
comes out with a new version that breaks some backwards compatibility.

I think I've seen this before, and it happened when we upgraded our PostgreSQL
JDBC driver to version 8.1.  I'm not sure what changed, since the API should
remain the same - only the driver should work better against PostgreSQL 8.1.
I assume that your CentOS installation runs the PostgreSQL 8.1 server as well?

Re: Centos 5 and NAV 3.2.2

Hi all,

I started this week with a clean system, installing nav on Suse 10.2

There was a problem with connecting to a remote database, for the time i 
use the local database, witch is OK for nav.

I get 3 problems:
1 I installed py-rrdtool-1.0b1, with the installation off 
py-rrdtool-0.2.1 I get a error:

   from the cron I get a mail with the next text:

Ok, if you need some tips on connecting to a remote database, please don't
hesitate to ask :)

I did not recognize the version numbers you mentioned, and checking up on
things seems to reveal that there is some confusion about which python-rrdtool
library to use.  Apparently there are two very similar libraries in existance:
One is distributed alongside rrdtool itself, and one is available at

Re: rrdtool and other problems on Suse 10.2

Thanks for your reply.

I removed the rrdtool, wich was from the suse media.
I compiled RRDtool 1.2.15 (the suse version was the same) and install it.
I recompiled psycopg-1.1.21,  the cronjob produced a error.

After this restartapache,tomcat,postgresql and nav
Even pping and servicemon started the first time.

No errormail from the cronjobs, everythings looks fine, til i login in nav:

error

File "/usr/local/nav/lib/python/nav/web/state.py", line 250, in __new__
    raise e

Maybe i have to rebuild more modules?

Re: Re: rrdtool and other problems on Suse 10.2

That problem solved, was ownership of a few files.

Everything looks fine, start playing with nav.

Re: IP address scope - graphical view / Traffic map load

Hi,

regarding..

> 2. On traffic map -- there is no  load on the link (Load: <0.01% No Data)
> but when I follow the link  (right clik - Load - this open the correct
> cricket graph .. and thre is  load on the link )

I fond this  in tomcat server logs:

SQLException for update statement: SELECT netboxid,descr,name,path,filename,key,value FROM
rrd_file JOIN rrd_datasource USING(rrd_fi
leid) WHERE subsystem='cricket' AND descr IN ('ifOutOctets','ifInOctets') AND ((key='gwport' AND
value IN (33,24,10)))
org.postgresql.util.PSQLException: ERROR: IN types character varying and integer cannot be matched

This seems to be related to postgresql  8.2.x restriction ( I have postgresql-8.2.4 installed). Is there
any  work around or the only way is to downgrade to a lower version of postgresql

tx,
Gheorghe

Ah, that explains why you're not getting any load data on your traffic map!

I don't see any workaround other than downgrading PostgreSQL :-(  I've just
looked at the code that creates the offending SQL statement - it looks hairy,
but I'll try to fix it.  I can post the patch here when it's done, if you like.

Great!  Just give a shout if there are any more problems :)
