rohithroki · Post by **rohithroki** » Tue Mar 22, 2016 1:05 am

Dear Team,
I am trying to configure https port for a non default port in nagios using the below command.

# ./check_http -S -H x.x.x.x -p 8080
I am getting the below error for the command

CRITICAL - Cannot make SSL connection.
139738252154728:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:769:

Kindly help me in fixing the error.

regards,
RKJ

I assume the webpage is working when you browse to
https://x.x.x.x:8080
What happens if you try:

Code: Select all

./check_http -H x.x.x.x -p 8080

hi rkennedy,rhassing

Thank you for your reply and apologies for the delay.

i have executed the below command in the nagios server and getting the below error

CRITICAL- Socket time out after 10 seconds

i have increased the time interval and checked and still i get the same error.Also telnet works fine for the below port .

What application is running on port 8080?

From the Nagios machine, please post the result of nmap x.x.x.x (where x.x.x.x is the IP you're attempting to monitor)

Weird, the port is open. Let's dig into it with curl.

Can you please run the following, and post the output back?

Code: Select all

curl -v "https://x.x.x.x:8080"

please find the result of curl command below

curl -v "https://x.x.x.x:8080"
