Hi, Is there a way to limit the particular user login only once in FC (or *nix)??or disabling the double logins. Currently a user can log in from different terminals using same account at same time and do various things. I have tried also Putty and able to login using same login name from windows machines. This is good for troubleshooting purposes like when situation goes wrong, user can log in from different terminal and fix it, but this also brings the anomali of two persons being present at the different place at the same time. I guess this is not an concern for desktop users but exposing as server might need considering this. At present my question is more on a curiosity than of practical use. Thanks!
