I originally put this question in the wrong forum so I am trying again here.
Is it possible to configure duo and ssh for linux such that a user only has to log in once a day to any particular server? The idea is to login once and then open as many other sessions as necessary. The admins here are used to using public key authentication or GSSAPI. Requiring them to do a push every time will cause a lot of grousing and I cannot blame them.
