Nagios Support Forum

hi,

all of our nrpe check's respond with status information: Invalid packet version received from server.
The status itself looks good.
On the XI server is Version: 4.0.3 installed.
All our clients using nsclient 0.5.2 or 0.4.4.19.

i have tried to execute check_nrpe with "-2" it doesn't work for us.

any ideas?

best Regards

Edit the check_nrpe command(or which ever command your config is using) and try this format:
I've noticed that the check_nrpe plugin expects the -2 or -3 option prior to the -c command and can throw an error otherwise.

Please provide the full command that you are running along with its output if the above doesn't help you to resolve the issue.

Hi,

if i use the command you provided without any addtional arguments i got:
[nagios@atvienag001 ~]$ /usr/local/nagios/libexec/check_nrpe -H atviectxpcm851.eumfgat.eumfg.immuno.baxter.com -2 -t 90 -c

If i use it with the arguments we need for:
[nagios@atvienag001 ~]$ /usr/local/nagios/libexec/check_nrpe -H atviectxpcm851.eumfgat.eumfg.immuno.baxter.com -t 90 -c check_powerstate -a $HOSTADDRESS$
CHECK_NRPE: Invalid packet version received from server.

What is the result of:
Also, are you replacing $HOSTADDRESS$ with a valid host address ?

it is independence which variable or command i useb, the error message ist the same but to answer your question, the variable will be replaced by the fqdn.

[nagios@atvienag001 ~]$ /usr/local/nagios/libexec/check_nrpe -H atviectxpcm851.eumfgat.eumfg.immuno.baxter.com -t 90 -c check_powerstate
CHECK_NRPE: Invalid packet version received from server.


[nagios@atvienag001 ~]$ /usr/local/nagios/libexec/check_nrpe -H atviectxpcm851.eumfgat.eumfg.immuno.baxter.com -t 90 -c $_HOSTCTX_DDC$
CHECK_NRPE: Invalid packet version received from server.

Run this on the command line:
provide a screenshot of the results.

this would be the correct format of the command

./check_nrpe -H atviectxddc051.eumfgdc.eumfg.immuno.baxter.com -2 -t 90 -c check_powerstate -a atviectxrdc001.eumfgdc.eumfg.immuno.baxter.com

result:

[root@atvienag001 libexec]# ./check_nrpe -H atviectxddc051.eumfgdc.eumfg.immuno.baxter.com -2 -t 90 -c check_powerstate -a atviectxrdc001.eumfgdc.eumfg.immuno.baxter.com
Powerstate seems to be OK

your example:
./check_nrpe -H atviectxpcm851.eumfgat.eumfg.immuno.baxter.com -2 -t 90 -c check_powerstate

Okay, so now we know that the command will work if given the proper arguments. Please provide a copy of the ccm database so I can take a closer look at the current configuration. Send it to me via a private message.

If the default database is being used then this can be done from the command line with:
If the database has been offloaded to another machine then you'll need to modify the commands slightly to look like:
Please provide the nagiosql.sql that is created.

Hi,

thank you the issue is resolved.
