Hey all,
this is sort of a wierd question, but bear with me. I notice that
pam_securetty has a function that allows people to have to be secure
before it will let them do something (for example, use login as root).
I've recently enabled telnetd on my system because of people trapped
behind library terminals at school, or behind retarded proxies on computer
labs where ssh apps are not installed.
The issue, of course, is that there's still technically the possibility of
someone using su(1) as a wheel user, over a session which is now insecure.
What I'd like to be able to do is be able to know which sessions are
ssh'd, and which sessions are telnet'd, and either require OTP for the
ones which HAVE been used for telnet -- or allow normal passwords for the
SSHable ones.
This would probably require modifications to either telnetd or sshd, as
most of the playing I've done with PS to make a proof-of-concept shows
both daemons as listing their terminals as ??, as opposed to showing the
terminalid's being used.
If nothing else, a PAM module that can tell what method a user is in via
would be useful.
Any ideas?
