How to add Cisco 6506 in MetaNAV
by davide＠wpweb.com 13 Apr '07

13 Apr '07

I just installed MetaNAV. I succesfully added catalyst 3550 device (after adding the proper OID in the type table). I cannot add a Cisco catalyst 6506: I added the type (1.3.6.1.4.1.9.5.45 ) but no modules are discovered from the device. # snmpwalk -v 1 -c public 192.168.10.101 .1.3.6.1.4.1.9.5.1.3.1.1.17 SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.1 = STRING: "WS-X6K-SUP2-2GE" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.2 = STRING: "WS-X6K-SUP2-2GE" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.3 = STRING: "WS-X6416-GBIC" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.4 = STRING: "WS-X6416-GBIC" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.5 = STRING: "WS-X6348-RJ-45" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.15 = STRING: "WS-F6K-MSFC2" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.16 = STRING: "WS-F6K-MSFC2" How can I add the above modules?

The reason for this is that it is quite impossible to create good generic config for servers in Cricket, and that the attempt NAV does spur a lot of errors . I strongly suggest that you make your own cricket-config for server statistics and remove the one present. To remove the existing config, delete the server-directory from $cricket/cricket-config, and edit the cricket-config/.nav-file (mind the dot) and remove servers from the dirs-variable. This will make sure the config will not be recreated. Then run compile from $cricket/cricket as navcron (sudo navcron ./compile). However, we are working on a new version of the script that makes cricket-config. This version will combine the advantages of the NAV-database and user-customization in a much better way than today. Both we and, I hope, our users look forward to this. :) Yours, -- John-Magne Bredal NTNU

The first happens as getDeviceData tries to update the database to register that a box supports a given SNMP OID. The second happens as NAV tries to update an entry in the swport table. You'd have to look at the code of the JDBC driver to be able to see what could cause NullPointerExceptions at those particular lines (AbstractJdbc2Statement.java:53 and AbstractJdbc1Statement.java:274), but I don't even know which version of the driver you are using. -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Thu Mar 15 12:40:27 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Thu Mar 15 12:40:30 2007 Subject: [Nav-users] NAV 3.2.1 from snapshot on ubuntu server problem In-Reply-To: <45F511D2.7080401(a)carnet.hr> References: <45F511D2.7080401(a)carnet.hr> Message-ID: <45F930AB.7010902(a)uninett.no> Silvije wrote, On 12-03-2007 09:39: > File "/usr/lib/python2.4/site-packages/mod_python/apache.py", line > 461, in import_module > f, p, d = imp.find_module(parts[i], path) > > ImportError: No module named nav > > > I am using apache2 and configured nav web as virtualhost on port 8888 > > Is this ok to do or not? > > I think I got all dependencies right. PYTHONPATH is set to > /usr/local/nav/lib/python... I'm not sure that Apache/mod_python would pick up on the PYTHONPATH environment variable, you might have to use some mod_python configuration parameters in your Apache config to specify the python path. A better approach for an installation from source on Ubuntu would be to add a file in /etc/python called 'sitecustomize.py', and add something like this to it: import sys sys.path.append('/usr/local/nav/lib/python') This module will be loaded by all Python programs that are run on your Ubuntu system. On another note, you should try the Debian package of NAV on Ubuntu. I think Ubuntu is similar enough to Debian for it to work, and it would make life a lot easier for you (dependency-wise, anyway). -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Thu Mar 15 12:48:56 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Thu Mar 15 12:49:02 2007 Subject: [Nav-users] LDAP Authentication In-Reply-To: <4ddd24660703120903gc499f13gfacb5ffaf19eba9c(a)mail.gmail.com> References: <4ddd24660703120903gc499f13gfacb5ffaf19eba9c(a)mail.gmail.com> Message-ID: <45F932A8.5080702(a)uninett.no> Greg Cooper wrote, On 12-03-2007 17:03: > Is anyone using LDAP to authenticate users on the web interface? > > if so, how did you go about doing it? First of all, take a look at this URL: http://metanav.ntnu.no/moin.cgi/LdapAuthentication Second of all, NAVs LDAP authentication ability is somewhat limited yet. It was modeled after the LDAP schema used at NTNU, and isn't quite configurable enough to suit any kind of LDAP schema people might care to implement. Specifically, NAV will grant access to all users in the configured subtree, which is not always desirable. At NTNU there were separate subtrees of user accounts for different systems; there was also a subtree of NAV accounts which contained only a fraction of the total amount of users. It also makes assumptions about which attributes are used to store account names and user names, etc. Fixing this isn't a very high priority at the moment, but if anybody cares to do something about it, the code is located in subsystem/webFront/lib/nav/web/ldapAuth.py . Patches will be greatly appreciated :) -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Thu Mar 15 13:33:08 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Thu Mar 15 13:33:11 2007 Subject: [Nav-users] Cricket/NAV problem In-Reply-To: <4ddd24660703121031h716cb122q8cee4ba790fc632(a)mail.gmail.com> References: <4ddd24660703121031h716cb122q8cee4ba790fc632(a)mail.gmail.com> Message-ID: <45F93D04.4080707(a)uninett.no> Greg Cooper wrote, On 12-03-2007 18:31: > I have some netboxes with IP/Hostnames in my /etc/hosts file.

When I go through > Cricket and browse to that box, I see the stats and it works fine. > Is there something I can do to fix this? I have a theory about what's going on. If you add an IP Device to NAV, and NAV is unable to do a reverse lookup of its IP address, it will use the device's IP address as its sysname (NAV always uses DNS names in the sysname column, for some old, obscure reason). So when makecricketconfig.pl generates cricket configuration, it sees that the name of the box is 10.8.250.3, and creates config based on that. It also registers in the rrd_file table that /usr/local/nav/cricket/cricket-config/../cricket-data/switch-ports/10.8.250.3/9_16.rrd belongs to this box. Then, later, NAV is able to perform a reverse lookup on 10.8.250.3 and sets the sysname of the box to DNS_NAME. Next time makecricketconfig.pl runs, it creates a cricket config entry for DNS_NAME, and ignores/discards the old 10.8.250.3 config. It also registers that /usr/local/nav/cricket/cricket-config/../cricket-data/switch-ports/DNS_NAME/9_16.rrd belongs to this box. So now, the rrd_file table says that there are two RRD files for the 9_16 interface of DNS_NAME. One of them might no longer exist, but it might sort first in the table, making the IP device browser attempt to use this file instead of the real one. I think you can fix it by running "cleanrrds.pl -r", which removes any entry from rrd_file that doesn't correspond to an existing file in the file system. This is just my best guess, though. I don't know why /usr/local/nav/cricket/cricket-config/../cricket-data/switch-ports/10.8.250.3/9_16.rrd disappears, though, as nothing in NAV deletes that. It might never have been created (e.g. makecricketconfig was run, but Cricket was never run until the DNS name had been resolved and makecricketconfig ran again). -- mvh Morten Brekkevold UNINETT >From annaliu at us.ibm.com Sat Mar 24 10:42:11 2007 From: annaliu at us.ibm.com (Anna Liu) Date: Sat Mar 24 18:42:24 2007 Subject: [Nav-users] Question in Configuring NAS Message-ID: <OFA51A9242.C09767EA-ON882572A6.006D229B-882572A8.00613DBD(a)us.ibm.com> I'm new in NAV.

Yes, we (UiO) uses LDAP for authentication. In /usr/local/nav/etc/webfront/webfront.conf : [ldap] enabled = yes server = ldaps://xxx.uio.no binddn= cn=yyy,cn=zzz,dc=uio,dc=no And if your ldap requires it (ours do), you allso need correct settings in /etc/openldap/ldap.conf.

You have probably not disabled SELinux like it says in the installation manual. Run this command as root to check: [root@nav3 ~]# sestatus SELinux status: disabled If you get something other than "disabled" you will either have to configure SELinux to work with NAV or disable SELinux. If you want to disable SELinux do this: To just test if this is the problem run this command: [root@nav3 ~]# setenforce 0 and try to reload the webpage. To disable it permanently edit this file: /etc/sysconfig/selinux to say: SELINUX=disabled and reboot the server. - Roger

Memory leaks in getDeviceData
by morten.brekkevold＠uninett.no 09 Mar '07

09 Mar '07

Some of you have noticed problems with getDeviceData running out of Java heap memory, and then getting out of sync with the PostgreSQL database driver - it ends up doing strange updates to the database. The issue is described in this bug report: http://sourceforge.net/tracker/index.php?func=detail&aid=1675508&group_id=1… For the technically inclined, here's a complete summary: I've traced the problem back to the Java SNMP package provided by drexel.edu. This package is used by the getDeviceData and getBoksMacs NAV processes to perform SNMP queries. The problem is an infinite loop, in which the library sends the same GETNEXT request over and over, and growing a list of SNMP responses until the heap is full. In a getDeviceData context, this problem can occur during OID testing of a device (This is when gDD attempts to figure which SNMP OIDs a new device supports). When the OID tester attempts to query an OID using GETNEXT requests, it uses the Java SNMP package's method for snmpwalking a MIB tree (retrieveMIBTable). If the OID is outside the MIB view of an SNMPv2c device, the device will respond with an SNMPv2 endOfMibView exception. Ufortunately, the retrieveMIBTable method of drexel's Java SNMP package treats this exception as just another value and adds it to the list of responses. Since the exception's object identifier is the same as the one used in the GETNEXT request, the method will continue to issue GETNEXT requests for the same OID until it no longer receives any response, or until it runs out of memory, whichever comes first. I've written two different patches to fix the problem in the Java SNMP Package, and I have submitted these patches to the upstream authors. The simplest patch is available at the aforementioned bug report page, for those who want to apply it themselves. I'm also planning to write a workaround for NAV. It is quite unnecessary for the NAV OID tester to walk entire SNMP tables just to test OID compatibility. Issuing a single GETNEXT request should be enough to determine whether the OID is supported or not. By doing this, the OID tester can avoid using the retrieveMIBTable method of the drexel library entirely. -- mvh Morten Brekkevold UNINETT >From gwc2004 at gmail.com Sat Mar 10 07:49:28 2007 From: gwc2004 at gmail.com (Greg Cooper) Date: Sat Mar 10 14:49:35 2007 Subject: [Nav-users] getDeviceData Java errors Message-ID: <4ddd24660703100549m38e8bf53l858b508ce07b4069(a)mail.gmail.com> Hi all.

Is there anything I should do after > following the RHEL/CentOS installation guide to configure cricket to handle > that many ports? 9700 ports are a considerable amount. Cricket is rather CPU and I/O demanding, so it depends a bit on your hardware. If you have dual CPU's you may get an increase in performance by configuring Cricket to use several processes. This is done by editing the subtree-sets file (located in the cricket-directory). This file defines the "sets" of directories you collect from. One set equals one process. Try to add one (or more) sets, preferably so that the number of ports in each set is about the same. Also remember to update the $NAVinstall/etc/cron.d/cricket file and add a cron-job for the new sets (the collect-subtrees job), and restart cricket with "nav restart cricket". NB: This will increase the CPU and I/O load on your server considerably. Cricket is not the most efficient program, and for bigger installations it is common to use a dedicated server (or more) for Cricket. At NTNU we are going to test this as we are currently only gathering data from a small subset of our network because of the load on the server. There was a discussion on the cricket-users mailing list some months ago (first post from 21. nov.) regarding this issue. It had the title "Huge Cricket installations". It seems that the forum is down (http://sourceforge.net/mailarchive/forum.php?forum=cricket-users) but if it comes up you can read that thread for more thorough information. > I read that collect-subtrees can collect from devices in parallel.
