My goal was to determine if the server is up using curl to ask for the Webserver Software version.
It should be and is "Microsoft-IIS"
Using "set -x" in my script showed me it may be "Microsoft-IIS"




The source of my current amusement is what appears to be the backwards logic in my "if" statement.
But trust me, in this case, it does opposite what it should?

Pseudo-code:
Ask server for version
If the string IS Microsoft-IIS/7.5\r ; then
write log file
exit 0
else
If the string is NOT Microsoft-IIS ; then
write log file
mail me

but if I change the IP to an Apache server, I don't get an email...


Any light to be shed on this would greatly be appreciated!
Or some real keyboard KungFu...
Ping is NOT an option for this script since the server will ping,
but the machine is in fact, unresponsive through normal channels.

Thanks and Happy New Year!

hi,

first don't forget to quote variables, it may break test if variable contains an IFS char.

there are many ways to test content\r
try this:
do you mean \r is not there all the time?

it was curious to me when I saw it...

curl -Is http://xxx.xxx.xxx.xxx| \grep -E '^Server' | cut -c9- spits out
"Microsoft-IIS/7.5"

but with "set -x" in the script, it shows it as "Microsoft-IIS/7.5\r"

variable $temp now quoted in if statement.

Thank you for your help.

another method, maybe?



the rubber-hits-the-road at
which leaves off the "/7.5" of the string "Microsoft-IIS/7.5"
NOW I can compare "$IIS" to "Microsoft-IIS"...?

fingers are crossed.

Thanks.

if you don't need serverType further, you can test directly

Watael:

Thanks for the options. I love 'em.
for now, all seems to be well using
"curl -Is "$website" | \grep -E '^Server' | cut -c9-21"

I tested my script manually 103 times yesterday and finally settled on the current script.
