Hi, I was starting to look at checkrad, and found (based on http://www.freeradius.org/radiusd/doc/Simultaneous-Use) that using "other" as the NAS-type will actually check only radutmp instead of looking at the actual NAS. Now, Could someone point me what would be the proper NAS type to use for each of the devices below(or the proper reference document to use)? I'm using the following NASes in my network: Monowall pfSense (3Com) Total Control PopTop (in Linux) What I want to do is to use checkrad as one of the steps to make sure that whoever appears as logged is really logged in, because I'm trying to use Simultaneous-use check, and some of the above (notably monowall) doesn't seem to be clearing properly sometimes. Thank you very much, Roberto Greiner -- ----------------------------------------------------- Marcos Roberto Greiner The optimists believe we are in the best of worlds The pessimists are afraid that this is true Murphy -----------------------------------------------------
