Status is OK

[wh1test]

Hi! You created very intresting plugin for Nagios. I installed your plugin exactly as you discribed in readme file. All nessesary perl modules installed too. My enviroment is Centos 5.9 i386, switch Cisco 2960 and check_cisco_config v.0.3. However when I execute the command I receive "Status is OK" all times:

./check_cisco_config.pl -H 10.15.222.55 -C snmpsecret -I 10.15.2.2 -T running -L /usr/local/nagios/cisco_configs -l /usr/local/nagios/tftp

Status is OK

Even I make changes in switch configuration and repite command I receive the same status! Here is content of folders:

ls -l /usr/local/nagios/cisco_configs/

total 4
drwxrwxrwx 2 nagios nagios 4096 Oct 31 21:59 10.15.222.55

ls -l /usr/local/nagios/tftp/

total 0

When I tried to use check_cisco_config v.0.2 I recieved:
TFTP transfer timed out after 30 seconds

Could you please ask how to resolve ?
Best regards, Yury

what are the contents of /usr/local/nagios/cisco_configs/10.15.222.55?

[wh1test]

ls -l /usr/local/nagios/cisco_configs/10.15.222.55

total 0
-rwxrwxrwx 1 nagios nagios 0 Oct 31 20:27 10.15.222.55-confg-current

cat /usr/local/nagios/cisco_configs/10.15.222.55/10.15.222.55-confg-current

Output of 10.15.222.55-confg-current always empty.

Looks like your configuration is not making it to the tftp server. Can you test manually sending your running config to the tftp server? From your 2960, copy running-config tftp and see what happens.

Hmm.. When I try to copy cfg I receive timeout. I can see these messeges in /var/log/messages:
Nov 3 21:02:42 nagios-srv in.tftpd[7209]: cannot set groups for user nobody

[wh1test]

Yes! It's works! I just changed config tftp to this:
{
socket_type = dgram
protocol = udp
port = 69
wait = yes
user = root
group = root
server = /usr/sbin/in.tftpd
server_args = -c -s /usr/local/nagios/tftp
disable = no
}

Awesome. I need to add some logic to detect empty and incomplete files.

Hey,

thanks for the Script!

Any news on "I need to add some logic to detect empty and incomplete files."?

[mrpaulmanley]

@virusmoere I haven't been using this plugin for a while, but i could give you some direction on this if you're comfortable implementing. I haven't tested this, but have done something similar in another script to parse the last line of a file.

in sub tftp_config add the following after the line with sleep (20);

#check if the last line of the config is "end" exit with critical status if not
  $lastline = `tail -1 $tftp_path . '/' . $device_name . "-confg-temp"`;
  chomp($lastline);
  if ($lastline neq 'end') {
    print "Incomplete configuration\n";
    #nagios interprets exit code of 2 as critical
    exit 2;
  }
