Scripting Help

[Newperson]

I am having trouble with a small script that I can't get it to do right. I am very new to Linux and can use some help. What I am trying to do is ping on a private network the other Linux machines to see if they are on-line. Two things I can use help on first the script will not show me which machine is responding slow and second the out come does not give me what I want to see. First the script.

pingtest() {
ping=`ping -c2 $1 | tail -2`
loss=`echo $ping | cut -d"," -f3 | cut -d" " -f2`
delay=`echo $ping | cut -d"=" -f2 | cut -d"." -f1`
if [ "$loss" = "100%" ] ; then
echo `date` $1 No Route to Host!!!!!!!! >>e.log
echo $1 No Route to Host!!!!!!!!!
elif [ "$loss" != "0%" ] ; then
echo $1 Not responding at all !!!!!!!!!!
echo `date` $1 Not responding at all >>e.log
else
if [ "$delay" -lt 10 ] ; then
echo $1 is responding normally
# echo `date` $1 is responding normally >>e.log
else
echo $1 is responding slow
fi
fi
}

Now the out come.

At the first ESP echo the line is messed up. What have I missed?

Welcome Newperson!

This script is part of a larger script, or maybe it gets input from another file??

Because it misses a newline character somewhere that is not showing in your example. I think.

[Newperson]

I see what you are saying. I will post the intire script and if you would look at it. I still cannot see the missing newline you spoke of. OH and thanks a million for you help.

I still cannot see the missing newline you spoke of.

Oh, but I do

It's this:

echo -n
echo -n
echo -n "###############ESP##############"

From the man:

Echo the STRING(s) to standard output.

-n do not output the trailing newline

I can see why you put them in the other lines, because it makes sense to suppress the newline character there. But not in the blank lines disappearing and the dividing line "###############ESP##############"
Remove the -n from those and you're done



EDIT:
You could also have done:

cat << EOF
       <snip>
       spare 132.147.160.67 `pingtest cat67`
       spare 132.147.160.72 `pingtest cat72`
       cath 132.147.160.71  `pingtest cat71`


       ###############ESP##############
       esp1 132.147.160.80  `pingtest esp1`
       esp2 132.147.160.81  `pingtest esp2`
       esp3 132.147.160.82  `pingtest esp3`
       <snip>
EOF

You were 100% correct on the -n I removed them and works fine. Funny how a little thing like that can make me scratch my head for two days. Now to the second part how can I tell which cat is responding slow on the network. The reason why I need to know is because some of the pc's here are problem areas and if it is a network problem I will remove the pc and replace it or check out the fiber and hub going to them. Once again thanks.

It's always the little things

Measuring response to a ping request is a crude measurement. So an individual measurement is very unreliable.


There are of course tools available that help keep an eye on your network performance. Nagios is one that comes to mind.

[Newperson]

Thank you for the reply. The network I admimistartor is on it's own network and is not and cannot be connected to the internet. The system is considered to be a life safty equipment for patients. There for I am bound to what is there software speaking. However I like the looks of Nagios and will consider installing it on my own network. Once agian thank you for solving my problem. Looks like I found the right forum.
