Need 'Ping' Program for Mandrake 9.2

[Guest esage]

Can anyone suggest a program [preferably a Mnk RPM] to ping my ISP? It has a shut off time of 15 minutes which is driving me crazy! I need one like the one I used to use on windows...but haven't found one for Linux. Thanx much.

open up a terminal/console and type in:

 

ping <ipaddress>

or

ping <hostname>

 

i.e.:

 

ping comcast.net

Cant help with the ping program but how about setting your email client to check mail every 5 minutes? That should keep the connection active enough.

[johnnyv]

ping -c 144 -i 600 ipaddress

 

will ping ipaddress 144 times with a 600 second interval between pings, adjust -c and -i values to taste. The current ping will last an entire 24hr period.

You could writes a bash script and either create and icon to execute it daily or schedule a cronjob to do it every day etc..

#!/bin/sh
# ping address every ten minutes for 24hrs
# change address to your isp's
ping -c 144 -i 600 192.168.0.1

So no fancy program needed here... just write your own little script. Now I am curious as to how to finish this and make it work.

 

Is this correct? (forgive my cli ignorance here)

I would type out that script in my favorite text editor and could save it with any name I want. When I want to run it, I would open up a terminal / konsole and type in that name I gave the file. Is that it, or am I missing something (like chmod that file somehow).

chmod u+x (or maybe just +x) <scriptname>

 

to execute (in a terminal):

 

./<scriptname>

k,

 

sarah31 deserves a too

This is my first crontab-stuff..so can anyone verify it...

if you would like to ping every 15 minute....:

 

make a textfile..let's call it... cronFile and type:

#ping ISP

*/15 * * * * ping <address> > /dev/null 2>&1

 

save it and do

 

crontab cronFile

 

and hope this works...I alwas ask myself what the 2>&1 means..anyone?

maybe you have to specify at the top of the file:

SHELL=/bin/bash

Will it always be executed or only when logged in..how do you specify that it has to run always..(if you're logged in or not) do it as root?

 

you have to run cron ofcourse....if you only run this thing(but it is more organised with cron ...), you could also make a script that does this at startup (my shell-syntax is probably wrong):

 

 

#!/bin/bash

while true

do

ping <address>

sleep 15 m

done

 

But the above ping command is maybe better...:) It are other ways...

This redirects the standard error (2) to the same output as standard output (1), the & simply means that any errors will be appended to the file instead of overwriting it.
