Mactrack Layer3 info missing

[bhoskins]

I have a new installation of mactrack 2.6.1 and have setup one site for testing/evaluation purposes. I currently have 1 site and 20 hosts in the mactrack database. (3 routers and 17 layer2 switches.) All of the switches appear to have been successfully polled/discovered, but I'm having trouble with the routers.

I have muddled through defining device types, and getting them matched to hosts successfully, however, I'm not getting ANY IP information from my routers ARP tables populated into the database mac_track_ips table for some reason. The consequence is that mactrack does not contain MAC/IP mappings nor is there any other layer 3 information. (IP Ranges, IP Addresses, etc.)

I've done everything in the tracking utilities console: database maintenance, refresh scanning functions, remove all results. I have also tried deleting and re-adding devices.

Please advise if there is something simple I may be overlooking? I've searched for mactrack documentation, but there does not seem to be much available. I have a fair bit of cacti game, but mactrack is a whole new animal for me.

Thanks,

B. J.

Likely they are being detected as layer2 only. Double check the device types. Also, run the macktrack_scanner.php manually to verify.

Hello Witness, thanks for the tip.

Looks like the device types are matching, as I would expect. However, when running mactrack_scanner.php manually for a given router, I get the following error message.

bhoskins@XXX[6] php -q mactrack_scanner.php -id=25 -d
DEBUG: HOST: 10.160.1.2 is alive, processing has begun.
DEBUG: Scanning function is 'get_standard_arp_table'
PHP Warning: Parameter 2 to get_standard_arp_table() expected to be a reference, value given in /var/www/cacti/plugins/mactrack/mactrack_scanner.php on line 192

I'm not a software developer, so I'm having a hard time stepping through the PHP...

181 /* for routers and switch/routers we need to push the ARP table to mac_track_ip table */
182 if (($device["scan_type"] == DEVICE_SWITCH_ROUTER) ||
183 ($device["scan_type"] == DEVICE_ROUTER)) {
184
185 /* verify that the scanning function is not null and call it as applicable */
186 if (isset($device_type["ip_scanning_function"])) {
187 if (strlen($device_type["ip_scanning_function"]) > 0) {
188 if (function_exists($device_type["ip_scanning_function"])) {
189 mactrack_debug("Scanning function is '" .$device_type["ip_scanning_function"] . "'");
190 $device["device_type_id"] = $device_type["device_type_id"];
191 $device["scan_type"] = $device_type["device_type"];
192 call_user_func_array($device_type["ip_scanning_function"], array($site, $device));
193 }else{
194 mactrack_debug("WARNING: SITE: " . $site . ", IP: " . $device["hostname"] . ", TYPE: " . substr($device["snmp_sysDescr"],0,40) . ", ERROR: IP Address Scanning Function Does NotExist.");
195 $device["last_runmessage"] = "WARNING: Scanning Function Does Not Exist.";
196 $device["snmp_status"] = HOST_ERROR;
197 }
198 }else{
199 mactrack_debug("WARNING: SITE: " . $site . ", IP: " . $device["hostname"] . ", TYPE: " . substr($device["snmp_sysDescr"],0,40) . ", ERROR: IP Scanning Function in Device Type Table Is Null.");
200 $device["last_runmessage"] = "WARNING: Scanning Function in Device Type Table Is Null.";
201 $device["snmp_status"] = HOST_ERROR;
202 }
203 }else{
204 mactrack_debug("WARNING: SITE: " . $site . ", IP: " . $device["hostname"] . ", TYPE: " . substr($device["snmp_sysDescr"],0,40) . ", ERROR: Device Type Not Found in Device Type Table.");
205 $device["last_runmessage"] = "WARNING: Device Type Not Found in Device Type Table.";
206 $device["snmp_status"] = HOST_ERROR;
207 }
208 }

Here is what's in my Cacti database for the device type ID and the host itself. Looks correct to me, no?

I would not worry about that warning message, it's just a warning. On the other hand, I would like to see your Cacti Log when this is happening. Also, I don't see any output related to the Arp table being scanned.

Thanks Witness,

A quick trip to Google with that error message yielded this post from May.

It fixed me right up.

That's really odd. Have to see what is going wrong. There should be nothing wrong with that function declaration unless the $device is uninitialized.

What versions of PHP are you all running?

Code: Select all

[1] php -v
PHP 5.3.2-1ubuntu4.2 with Suhosin-Patch (cli) (built: May 13 2010 20:01:00) 
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies

There was never any further comment. I would be curious to know if it's going to break anything else later.

Thanks again,

BJH

Wish these guys would open bugs for this... Can you do that?
