Zabbix Telnet Script

[PingPong93]

Hello Guys

I would like to ask for your guidance on creating custom script on zabbix

I have already tried to do a custom script for telnet command on my zabbix server as shown in attached file.

But when I tested it on my Maps, it show "cannot execute script" as shown below


When I try to manually telnet the server, it show ok as shown


Is there anything wrong on my telnet script?

In the action, you can use the command to finish processing.

By setting only the connection with the telnet command,
telnet will be waiting for input without terminating processing.
In other words, processing of the command does not end so it can not be used.

What do you want to connect by telnet and execute?

Thanks Atsushi

I have use remote command on my action, but I insist to do global script that can run on maps.

Any suggestions? I would like to telnet my zabbix servers and execute the result.

If you want to execute a command using telnet, it would be a good idea to write a script to do that.
Since interactive response processing is required when connecting via telnet, there is a method of using the expect command.

If it is a UNIX like OS, you can execute the command with the following script.

#!/bin/sh
host_ip="192.168.1.1"
login_user="user1"
login_pass="password"
exec_command="ls"

expect -c "
        set timeout 5
        spawn telnet ${host_ip}
        expect -nocase \"login:\"
        send \"${login_user}\n\"
        expect -nocase \"Password:\"
        send \"${login_pass}\n\"
        expect \"$ \"
        send \"${exec_command}\n\"
        expect \"$ \"
        send \"exit\n\"
"

Please customize it according to what you want to do.
