Routerconfigs plugin / how it works?

dieselboy · Post by **dieselboy** » Fri Mar 26, 2010 9:13 am

Doesnt this part of routerconfigs work for you any more? When I disable the checking of the configs, I still have the diff functionality. The only thing I disabled was to delete the config if it doesnt meet the criteria. Everything else seems to work fine.

Nope, I seem to have busted it totally. It works for all other devices but not the HP stuff. The script thinks that it errors out, thus it isnt aware that its actually written a file to tftp. lol

Oh, so the config file count still remains at zero even though there are files there?
Does it make a difference if you specify a new folder? As the functions file will check and create a new folder with propper permissions if there isnt - not sure if this will have any different outcome

Attached is the updated functions file. RouterConfigs is now working for both Cisco & HP devices. (I've tested using a few of each) In order for this to work your HP devices need a username and a password. To configure them in that manner do the following and it'll prompt you for a password.

Code: Select all

#password manager <username>

You'll also need to update the plugin_routerconfigs_devicetypes table. Make sure that you replace x.x.x.x in the below insert with the IP address of your tftp server.

Code: Select all

mysql> insert into plugin_routerconfigs_devicetypes (id, name, username, password, copytftp, version, confirm, forceconfirm) values ('', 'HP', 'sername', 'assword', 'copy running-config tftp x.x.x.x', 'sh ver', '', '');

I'm sure that there are better / cleaner approaches to take here. But, this works and all functionality in the RouterConfig UI has been maintained.

Let me know if you run into problems.

Thanks for posting this, I ran the SQL database command and I also copied your functions.php over. The problem I have is whenever I try to back up the HP device the page displays a load of php errors and no device is backed up.

Not quite sure of what is wrong. The debug just shows the initial telnet screen of the HP device "press any key to continue"
Any ideas?

Very strange. It's failing now for me as well. I'm looking into root cause.

What a wonky issue this turned out to be. On initial run it should have worked, and did for me last Friday. However, on 2nd run it would connect, upload the config to tftp and error out. The problem was caused by the following code:

Code: Select all

                        if (substr($d, 0, 9) == 'hostname ') {
                                $filename = trim(substr($d, 9));
                                if ($device['hostname'] != $filename) {
                                        db_execute("UPDATE plugin_routerconfigs_devices SET hostname = '$filename' WHERE id = " . $device['id']);
                                }
                        }
                        if (substr($d, 0, 17) == 'set system name ') {
                                $filename = trim(substr($d, 17));
                                if ($device['hostname'] != $filename) {
                                        db_execute("UPDATE plugin_routerconfigs_devices SET hostname = '$filename' WHERE id = " . $device['id']);
                                }
                        }

When HP devices were thrown through the above if statements the substr function tripped on itself and triggered a false positive. It'd look at $hostname and compare that to $filename. $filename is defined above and is $hostname in quotes. ($filename vs "$hostname") Thus it evaluated it to false, and appended the device name in the plugin_routerconfigs_devices table using db_execute. Since it'd modify the table it'd then break on each subsequent run b/c "hostname" will never equal hostname. I've fixed this as well as cleaned up the functions file. (added some comments and removed redundant code that I'd added)

I've been able to successfully complete backups for a mixed bag of devices. (IOS, IOS without needing enable, HP)

Give it a go using the attached functions.php and let me know how it goes. -Naturally make sure to back your original working one up prior.

Nice work, I will give it a try now. Thanks for the update

dieselboy · Post by **dieselboy** » Tue Apr 06, 2010 4:46 am

I can't seem to get that working either. I setup a packet capture and cacti only initiates a telnet session. The session closes and about a minute later the cacti screen refreshes with php errors. The HP device never tries to upload a config
I'm not sure what the problem is :/

grady · Post by **grady** » Tue Apr 06, 2010 8:55 am

The stuff that's echoed out and saved as debug likely is worthless in figuring out what the problem is. Can you do a select * from plugin_routerconfigs_devicetypes; and post that output here? Also, on your HP switch you've configured it such that it requires a username and password? Did you replace your existing functions file with the one I posted or did you add stuff from mine to yours? Finally, from a command line run php /path/to/cacti/plugins/routerconfigs/router-download.php and watch the output there. That'll give you a better idea of why it isn't working.

I'm not sure how to do a select from plugin command?

Here is the output when I run the routerconfigs php from the command line as you describe:

I used your complete functions.php as I wanted to ensure that was working before I played with the config.

It almost looks like an error with the plugin_routerconfigs_devicetypes table. All you need to do to get that output (assuming your mysql instance for cacti is on the same host, and when you installed you used cactiuser / cactiuser for mysql login)

1. mysql -u cactiuser -p
2. use cacti;
3. select * from plugin_routerconfigs_devicetypes;

Thanks for explaining that! I have never really used mysql from the command line. I installed phpmyadmin to use the mysql database.
Here is the output:
