Thanks for your answers.

I don't know how works the OID 1.3.6.1.4.1.2201.8. I will search more
information about it. Thanks for this solution.

About HOST-RESOURCES-MIB::hrSystemNumUsers.0, it returns number of opened
sessions, include ssh. I just want to see if a session is opened in a tty.
But thanks too for your help =)
