Greetings All,

So many responses to my check_http proxy query!  Thank you all.

I do, however, have another spanner to throw in the works, as below: proxy authentication.  ;)

I tried this, and it works fine as long as your proxy doesn't require authentication.  Of course, at least one of the ones I monitor requires authentication.

Check via unauthenticated proxy:
---
# ./check_http -vvv -I 192.168.0.8 -p 3128 -H www.google.com -u http://www.google.com/index.html

GET http://www.google.com/index.html HTTP/1.0
User-Agent: check_http/v2053 (nagios-plugins 1.4.13)
Connection: close
Host: www.google.com:3128

http://192.168.0.8:3128http://www.google.com/index.html is 826 characters

Check via authenticated proxy (details provided for <proxy>/<user>/<pw>)

# ./check_http -vvv -I <proxy IP> -p 8081 -a <user>:<pw> -H www.google.com -u http://www.google.com/index.

GET http://www.google.com/index.html HTTP/1.0

CRITICAL - Socket timeout after 10 seconds

Any thoughts?  I think the problem is that the -a switch is a reference to authentication on the Host only.  Not sure how to pass authentication to the proxy.

Note also that I am checking from the Nagios box itself, as I am trying to determine functionality of the web access, rather than from the W2K3 server that acts as the proxy.
 
Cheers,
Mark
