Stuart, The following does not seem to be true unfortunately: "Currently the IP address shown in LON-CAPA in grade details is the stored IP address of the remote client from which the submission was made."
I submitted some response from the machine connected directly to the university network. The IP address displayed in the grade details was not the IP address of my machine. I then also submitted an answer from another machine connected via VPN. In both cases, the IP address displayed in the grade details was the same. Thanks, GS -----Original Message----- From: LON-CAPA-users [mailto:lon-capa-users-boun...@mail.lon-capa.org] On Behalf Of Raeburn, Stuart Sent: Monday, August 19, 2019 17:49 To: Discussion list for LON-CAPA users <lon-capa-users@mail.lon-capa.org> Subject: Re: [LON-CAPA-users] IP address of student submission GS, Currently the IP address shown in LON-CAPA in grade details is the stored IP address of the remote client from which the submission was made. The IP address recorded in the submission transaction for each student is the value of: $ENV{'REMOTE_ADDR'}. Note: a situation where that IP address will be a LON-CAPA server's own IP address is when you are viewing grade details for transactions resulting from bubblesheet grading (of a printed exam), by a Course Coordinator. The IP address might also be different from a student's actual IP address if students at your institution use an institutional VPN, or a proxy for web access to your LON-CAPA instance.

In the grade details I can see the host name and the IP address, which is not the user IP address but the IP address of the LON-CAPA server. Being able to track the student IP address would be very helpful to prevent cheating. Some students these days simply allow paid "ghosts" to login and solve the problems for them.
