Example 1 Disallowing ssh none authentication




 sshd-none      auth       requisite   pam_deny.so.1


 sshd-none      account    requisite   pam_deny.so.1


 sshd-none      session    requisite   pam_deny.so.1


 sshd-none      password   requisite   pam_deny.so.1

Example 2 Disallowing any service not explicitly defined




 other          auth       requisite   pam_deny.so.1


 other          account    requisite   pam_deny.so.1


 other          session    requisite   pam_deny.so.1


 other          password   requisite   pam_deny.so.1

See attributes(7) for a description of the following attributes:

ATTRIBUTE TYPE ATTRIBUTE VALUE
Interface Stability Evolving
MT Level MT-Safe with exceptions

syslog(3C), libpam(3LIB), pam(3PAM), pam_sm_authenticate(3PAM), nsswitch.conf(5), pam.conf(5), attributes(7), pam_authtok_check(7), pam_authtok_get(7), pam_authtok_store(7), pam_dhkeys(7), pam_passwd_auth(7), pam_unix_account(7), pam_unix_auth(7), pam_unix_session(7), privileges(7), su(8)

The interfaces in libpam(3LIB) are MT-Safe only if each thread within the multi-threaded application uses its own PAM handle.

The pam_deny module is intended to deny access to a specified service. The other service name may be used to deny access to services not explicitly specified.
