If host is up

RouterOS Beginner Basics
1

I’m looking to write a script that checks to see if a host is up (as a boolean) so I can use it in an if statement.
I wrote this but not working :frowning:

:if (string.find([/tool/ping address=192.168.0.5 count=1],“timeout”) ) do={ :put “value is false” } else={ :put “value is true” }

:if (:find [/tool/ping address=192.168.0.5 count=1] “timeout” 0 ) do={ :put “value is false” } else={ :put “value is true” }



Also the scripts in netwatch (the ‘test’ script), are arguments passed into these at all?

if (write.at.random true) what do you expect?


:if ([:ping address=192.168.0.5 count=1] = 0) do={
    :put "reply NOT received"
} else={
    :put "reply received"
}

Yes, I got the echos incorrect on my first post as I had copied it, but it still gave the same text if the host was up or down.

Unfortunately, the code you gave does not appear to work either.

[j@MikroTik] > /system script run script1
Columns: SEQ, HOST, SIZE, TTL, TIME
SEQ HOST SIZE TTL TIME
0 1.1.1.1 56 58 25ms735us

Why not???

Nex time specify that you use RouterOS v6 or v7…


for v7:

:if ([:typeof ([:ping address=195.168.0.5 count=1 as-value]->"time")] = "nothing") do={
    :put "reply NOT received"
} else={
    :put "reply received"
}

Fixed it for you, in the spirit of the title! :slight_smile:
