I am getting these errors in my collector logs. Cricket isn't collecting from some router due to an snmp.pm error.

I need to make the target types for all my serial interfaces 'standard-interface" instead of them using the --default-- of snmpv2-interface. I can change the targets files manually, but how do I keep makecricketconfig.pl from rewriting them and breaking them? Or more to the point, how do I make the makecricketconfig.pl script do this for me? Thanks!

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.

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.

You probably mean bridge table, anyway, are you sure? For Cisco I've read that you can do this: "You can generate SNMP traps whenever a MAC address change occurs by enabling the set snmp trap enable macnotification command in conjunction with enabling the set cam notification and set cam notification historysize commands." I haven't tested it yet, maybe someone out there has? We have SNMP trap on TODO for NAV 3.3, we are thinking of an implementation that can trigger certain scripts on a given snmp trap oid. We see to very interesting use cases: * when linkdown/up trap is detected update the cooresponding link value in the swport/gwport database table. * when a new mac address is seen/gone trigger a script that opens/closes corresponding machine tracker records (cam table). This script could also post alarms regarding wanted mac addresses. - Vidar

Can this be done today? On a small scale such as having only 1 MAC address that you need to catch, you could configure your DHCP servers to assign this MAC a specific IP.

Get error when adding IP device "Gw router - layer 3 device"

Some devices also return integer values for serial numbers instead of strings - attempting to encode an integer object as if it were a string will fail miserably, as in your case. I've just committed a fix for this to the repository (r3785). We're expecting to release NAV 3.2 within a few weeks, so I don't think you will see this in a bugfix release before that. Several others have reported this problem, and a workaround has been suggested: Use bulk import to insert the devices that cause this error - the serial numbers are not retrieved and checked in this manner during a bulk import. -- mvh Morten Brekkevold UNINETT >From barbieri.marco at unimore.it Mon Jan 8 12:06:48 2007 From: barbieri.marco at unimore.it (Marco Barbieri) Date: Mon Jan 8 12:07:05 2007 Subject: [Nav-users] Problem with HP 9304m & vlan Message-ID: <200701081206.48961.barbieri.marco(a)unimore.it> Hi all, i'm trying to use NAV 3.1.1 in my environment, my main problem seems to be that my network in mainly based on HP router/switches: 9304m (foundry/hp), procurve 5304, 5308, 2824 etc.. and a couple of cisco. I don't have cdp active on any machine, the net is ospf based and snmp enabled. The Cisco machines are fully understood, i can see the vlans that are there defined, counters and so on, everything is fine. Some HP machines are understood too or a sort of mainly Procurve family 25xx e 53xx even if i can't see the vlans that are defined on those router/switches. Hp/Foundry 9304m is the worst understood: non only it doesn't show any defined vlan but it doesn't show the expansions slots that are fitted in the chassis.

Roger: Thanks for the gracious and quick response to my simple problem. I just could not see how the installation could proceed without being logged in as root and your response has provide both the rational for the local user creation, and a good approach to completing the install away from the server room. Thanks for the PuTTY link. To answer your last question.. I am using the "InstallingOnRHEL4 for v3.1" with the edits by Morten Brekkevold; ### 14.11.2006 by Morten Brekkevold: ### - Updated for NAV 3.1.1. ### - NOT TESTED Thanks again, the help was much appreciated.

Newbie Problem loading NAV on CentOS 4.4
by rkillick＠niagara.com 17 Nov '06

17 Nov '06

Hello: I am trying to load NAV 3.1.1 onto a basic CentOS4.4 installation. My problem is likely embarrassingly simple and concerns a point near the start of the "InstallingOnRHEL4" document for NAV3.1.1. .. at the section. ## ## Make a local user ## useradd -c "John Doe" nn passwd nn .. I create a simple user called "NAVNIA" as well as an appropriate password. Soon thereafter you are asked to reboot and log in as the new user. .. Logged in as NAVNIA, that user has no root privilege or access to root level commands that now have to be executed to complete the install. While I know it is best practice not to run as root, I just don't get what I need to do to have the new user (NAVNIA) complete the install. It doesn't seem right to simply su root every time you need that privilege. As I siad. a very basic question I'm sure, but my MS-Windows admin experience is simply no help here and my access to Linux help is simply zero. I am quite interested in getting NAV up and running as a means of show-casing the OpenSource possibilities as well as hhoping to see a viable alternative to our Pergrine PND NMS. Our network has about 1600 devices and NAV looks very inviting! Any insight would be appreciated. Bob Killick

Ah. I discovered that myself while creating the bug you just pointed out ;) I got tired of AlertEngine's incessant verbosity when start/stopping and querying for status, so I changed its init-script to use the shell-script based pid-file probing. The "garbage" is actually a unix timestamp, referring to when the alertEngine daemon was started. When querying the alertengine program directly (as in pre-3.1.1), it would use this to tell you how long it had been running. Why on earth the author put it in the pid file, I don't know. I thought about removing the timestamp completely from the pid file as I changed the init script, as it bothered me somewhat - but in my Linux-centric world it worked fine without removing it.

Cisco port numbering, suggestions?
by morten.brekkevold＠uninett.no 12 Okt '06

12 Okt '06

Greetings everyone, This post may become rather lengthy, but if you are interested in Cisco module issues and port numbering vs. interface names, please bear with me. I would really appreciate some feedback from our users, as the changes we are implementing will affect everyone. Removing the "submodule hack" ----------------------------- This summer I worked on fixing some of the problems with module detection on Cisco equipment. There were several problems related to the fact that gDD attempts to map Cisco's submodule paradigm in to NAV's data model by assigning module number 10 to submodule 1/0, number 11 to submodule 1/1 and so forth. Apparently, there isn't much equipment that actually employs submodules, and oftentimes these modules will not be self-sustainable devices, as in the case of the 3750 Metro. The basic metro reports two submodules, the first (1/0) contains 24 Fa ports and two Gi ports, while the second (1/1) contains two Gi ports. Basically, the Metro is just one physical device, and with the code changes I've made, the Metro will appear in NAV as one single module with 28 ports. Meaning that submodules are largely ignored by NAV, which now attaches the ports of all submodules to the top module itself. Port numbering -------------- As you may know, NAV assigns port numbers to switch interfaces. I'm told this is an old convention stemming from the old CatOS CLI implementation, where interfaces only had port numbers and not names. In many parts of the user interface, NAV refers to switch interfaces only by their module and assigned port numbers. In the Cisco case, NAV assigns (or rather, used to assign) port numbers by interpreting interface names and/or descriptions. This means that Fa1/5 would become port 5 on module 1, and Fa2/0/3 would become port 3 on module 20 (!). On devices with both Fa and Gi interfaces, Cisco reuses these numbers. A module would have both an Fa1/1 and a Gi1/1 interface. NAV would assign the port number 1 to the Fa1/1 interface, and when it found the Gi1/1 interface, it would see a port numbering conflict and assign the ifindex value of the Gi1/1 interface as its port number (typically resulting in something like 10101 as its port number). With the submodule changes described above, the code will rely more on the the portIfIndex table from the CISCO-STACK-MIB [1]. This table enumerates the interfaces of a Cisco stack into modules and port numbers. For a Metro 3750, this table will actually enumerate all 28 interfaces as port 1 through 28 on module 1. I've received some criticism for this from people running NAV from the latest trunk revisions, though. Apparently, many Cisco devices will enumerate Gi interfaces before Fa interfaces, meaning that Gi1/1, Gi1/2 and Fa1/1 will become ports 1, 2 and 3 in that order. This represents a change in the port number assignments that NAV has made earlier. Previously, it would have started assigning port numbers to the Fa interfaces first (either because their ifindex values are lower, or because they sort first alphabetically). Consequently, if you upgrade your NAV installation to the trunk (or the upcoming 3.1.1 version), any switch you have that has both GigabitEthernet and FastEthernet interfaces will have its ports renumbered in NAV. The complaints I've received about this largely revolve around the fact that some users have implemented external systems that relate to NAV by referring to module and port numbers, and that this reference breaks when NAV suddenly decides to assign new port numbers. A typical example of this would be that when searching for a MAC address in the Machine Tracker before the change, you might be told a machine is connected to foo-sw, module 1, port *5*. Then you upgrade NAV, perform the same search in the Machine Tracker, and now you are told the machine in question is connected to foo-sw, module 1, port *7*. The interface name in these two cases will remain the same, e.g. "FastEthernet1/0/5" or "Fa1/0/5", but this string is not available in the Machine Tracker (yet). Numbering vs. names ------------------- Now, other feedback we've received (both internal and external) tells us that today, port numbers are largely irrelevant in real world situations. Several network engineers have told us that they care about interface names (the ones they see on the CLI, such as Fa1/5), rather than arbitrary port numbers. Their viewpoint is that NAV should place more importance on interface names than on port numbers, meaning we should put interface names in all parts of the user interface that has port numbers today, including the Machine Tracker. The NAV dev-team is leaning towards the latter solution, but this is too big a change for the 3.1.1 bug release, and we might not even have time to do it for version 3.2, which is scheduled for late October. The question is, what do you, the users, think about this? The situation, as it stands, is that a new port number assignment scheme will turn up in the 3.1.1 bug release, because of the submodule bugfix. This may confuse some people, as interface names are not readily available in many parts of the user interface. Should we try to stay with a numbering scheme compatible with the old one for the 3.1.1 release, and wait for interface names in the UI before we change the port numbers? This might delay the 3.1.1 release even further, as we need to make changes to the standing bugfix before the release. Is it okay to renumber ports in the 3.1.1 release, as long as interface names become more prominent in the UI in the 3.2 or 3.3 release? Should we prioritize more prominent interface names in the 3.2 release, or is it okay to wait until the 3.3 release? Now's your chance to influence these decisions, before further implementation takes place.

Actually, Morten Werner is sitting next to me working on that right now. He came up here from Oslo on Wednesday to have a little brainstom/workshop with us. He's also uploaded a preliminary 3.1 package to the official Debian unstable archives, which hopefully means that NAV 3.1 will be part of the next Debian stable release. That said, he's also backporting a 3.1 package for the current stable release. These new packages will also feature automatic database initialization and upgrades on install. > Anyway, when running makecricketconfig.pl i get this error message: > > Use uninitialized value in pattern match (m//) at > /usr/lib/nav/makecricketconfig.pl line 927 > > This happens when it process a switch named nara-sw002-01 (catalyst > 3524XL) > > Anyone know about a fix for it? I don't. But what's on line 927 of /your/ makecricketconfig.pl anyway? I'm looking at makecricketconfig.pl from NAV 3.0.1 (which is in the latest Debian package), and that line is a comment: # Write to file. -- mvh Morten Brekkevold UNINETT
