By +default, the kernel does not audit input on any TTY. + +OPTIONS + +disable=patterns + + For each user matching patterns, disable TTY auditing. This overrides any + previous enable option matching the same user name on the command line. See + NOTES for further description of patterns. + +enable=patterns + + For each user matching patterns, enable TTY auditing. This overrides any + previous disable option matching the same user name on the command line. + See NOTES for further description of patterns. + +open_only + + Set the TTY audit flag when opening the session, but do not restore it when + closing the session. Using this option is necessary for some services that + don't fork() to run the authenticated session, such as sudo. + +log_passwd + + Log keystrokes when ECHO mode is off but ICANON mode is active. This is the + mode in which the tty is placed during password entry. By default, + passwords are not logged. This option may not be available on older kernels + (3.9?). + +NOTES + +When TTY auditing is enabled, it is inherited by all processes started by that +user. In particular, daemons restarted by a user will still have TTY auditing +enabled, and audit TTY input even by other users unless auditing for these +users is explicitly disabled. Therefore, it is recommended to use disable=* as +the first option for most daemons using PAM. + +To view the data that was logged by the kernel to audit use the command +aureport --tty. + +The patterns are comma separated lists of glob patterns or ranges of uids. A +range is specified as min_uid:max_uid where one of these values can be empty. +If min_uid is empty only user with the uid max_uid will be matched. If max_uid +is empty users with the uid greater than or equal to min_uid will be matched. + +Please note that passwords in some circumstances may be logged by TTY auditing +even if the log_passwd is not used. For example, all input to an ssh session +will be logged - even if there is a password being typed into some software +running at the remote host because only the local TTY state affects the local +TTY auditing. + +EXAMPLES + +Audit all administrative actions. + +session required pam_tty_audit.so disable=* enable=root + + +AUTHOR + +pam_tty_audit was written by Miloslav Trmač . The log_passwd +option was added by Richard Guy Briggs . + -- cgit v1.2.3
