[LON-CAPA-users] IP Ranges and Slots

[Mills, Douglas G]

Ok, it looks like the problem I was having was due to the fact that apparently you have to log out of Lon-Capa and back in when changing IP addresses in order for the change to take effect.  I was testing that the resources were blocked, changing my network connection to one with IP numbers that would be in range but continuing to see them blocked.  In testing with just my own IP address I'm seeing now that I have to log out of Lon-Capa and log back in for Lon-Capa to know that my IP address has changed(?)  Does that make sense with how Lon-Capa works — it registers my IP address when I log in and holds onto that address for my entire session (or perhaps updates it sometime down the road but NOT instantly when the IP changes at least)?

I need to test with the target network tomorrow in another building, but that appears to explain what was happening based on my own computer's IP address.

Subject: IP Ranges and Slots

HI Colleagues,

I have an IP range of
172.16.76.2 - 172.16.77.254 .

I'm trying to set up a slot that allows access only from that range.  I set it up as
172.16.76.[2-254],172.16.77.[1-254]

Based on instructions I found I believe in an archived discussion list posting that says:

"You can enter multiple IP ranges by separating with a comma.

Supported formats for each range are:
35.8.*

or
35.8.3.[34-56]

or
*.msu.edu

or
35.8.3.34

or
somehostname.pa.msu.edu"


This is not working. Any idea what I am doing wrong?  Thanks!
