ttysnoop

ssh mit ttysnoops kompilieren ... /configure --with-login=`which ttysnoops` (schaut besser aus :) in der config file uselogin yes oder so...

limitierung ttysnoop: 1.) fenstergrösse ist auf 80x25 limitiert 2.) funktioniert nicht mit NIS!

ttysnoop ttypX ...

dpkg-divert --divert /bin/login.real --add /bin/login
mv /bin/login /bin/login.real
echo "* socket login /bin/login.real" > /etc/snooptab
cp /etc/inittab /etc/inittab.valid
perl -p -i,orig -e 's#getty#getty -l /bin/login.real#g' /etc/inittab .. für lokale sessions, aber auch beachten
ln -sf /usr/sbin/ttysnoops /bin/login
init q
echo "UseLogin yes" >> /etc/ssh/sshd_config bzw /usr/local/etc/sshd_config
/etc/init.d/ssh restart

das selbe in bsd

watch -W ttypx

NIS

[yp]chfn - lokal/NIS change username and information
[yp]chsh - lokal/NIS change shell
ypwhich - return name of NIS server or map master
ypmatch - print the values of one or more keys from a NIS map
ypset - bind ypbind to a particular NIS server
yppoll - return version and master server of a NIS map
yppush - force propagation of changed NIS databases

utmp

utmp, wtmp - login records

#include <utmp.h>

       The  utmp file allows one to discover information about who is currently using the system.  There may
       be more users currently using the system, because not all programs use utmp logging.

       Warning: utmp must not be writable, because many system programs (foolishly) depend on its integrity.
       You  risk  faked  system logfiles and modifications of system files if you leave utmp writable to any
       user.

w, who relies on utmp also file leeren und weit und breit wird kein user mehr in sicht sein ...

beim aufruf von deluser(script)/userdel(bin) wird utmp bevor der user wirklich gelöscht werden kann kontrolliert ob er wirklich noch eingelogt ist...

logout ist (afaik) z.b verantwortlich dafür das der user nach dem auslogen aus dieser file gelöscht wird

sollte ein user root rechte haben und sich etwas auskennen kann er sich mit diesem feature verstecken (sample "exploits" sind natürlich wieder überall erhältlich...) einzige kontrolle terminals /dev/pts/...
