My organization has a Shibboleth/IDP service set up. Now that I am getting involved, I am first setting up my own basic IDP on a test server to learn the ropes. In order to test functionality, I want to be able go to one of our production sites and -- if accessing it from my workstation in the office -- have the login be redirected to my IDP instead of the main production IDP. I think I should be able to do this locally without affecting anyone else by editing IP routing rules on my machine in /etc/hosts/ or iptables, but I'm not sure how and I'm pretty new.

Basically, I'm wanting to add a condition locally on my machine such that if I try to access https://productionsite.domain/secure/login, my local routing rules redirects me to my own IDP. Is this possible?

I have a simple method that I am using on four subnets to determine which registered IPs are actually up and active, and which ones can be removed.

Initially, I iterate through the list of domain names with this command:

sudo nmap -sS -O -v oN $filename $name

$filename is my output file for that IP and $name is the domain name that was read in.

From that command, for all IPs that reported 'host down', I run this command:

sudo nmap -Pn -sS -O -v -oN $filename $name

Note that the only difference here is that I am now assuming the host is up, just to see what comes back.

In all the cases I've seen thus far, however, all the ports that are scanned are filtered, and since the host is assumed to be up, I don't have a way to verify that it actually is up after this second scan is run.

Any other ideas?
