[TriLUG] OT sanity check on proxy servers

[Justin L. Skinner]

I say bull.

But a few things to check.
A) What's the end user's IP address ?  get it at www.whatismyip.com
B) What's it resolve to ?  get it at www.dnsstuff.com
C) What's a trace route look like between your end user and the website ?
D) Is the site themself maybe running a  reverse proxy and they don't even know it.. if you called first level support it's quite possible.
E) Maybe the end user is using Squid or something..and doesn't know it.

I guess it would also be good to note what the problem is. 

Connection error, latency, random content errors.


Hope that helps.

Cheers,
Justin

* One of my end users is having a problem with an external site.  The vendor

* problem.  I reply but we are not running xxx proxy.  Vendor says "that 
* doesn't matter, you could run across xxx proxy anywhere in the path from 
* you to me and that will cause the problem".  I'm calling bull... I'm not

* Internet, am I?
