The easiest way is to a cut-and-paste.
put the commands:
enable
<password>
conf t
line con 0
exec-time 30
line vty 0 4
exec-time 30
then copy it to your clipboard and paste it to your terminal from the
console. Though I have seen one guy that did it just by typing, the trick
is you cannot stop typing. You don't have to change the setting in under
one second, you just can't stop typing until you are done.
