Nella mia azienda, quando accedo ad alcuni server, vengono visualizzati il mio ultimo accesso e un enorme banner:
me@my-laptop$ ssh the-server

me@the-server$
Ovviamente, non voglio che questo enorme banner venga visualizzato ogni volta che eseguo l'accesso, ma vorrei mantenere l'ultimo orario di accesso e l'host visualizzati .
Se uso touch ~/.hushlogin
, il banner non viene visualizzato ma perdo anche le
ultime informazioni di accesso . In realtà, non viene visualizzato nulla:
ssh the-server
me@the-server$
Come rimuovo il banner ma mantengo l'ultimo tempo di accesso e host, in questo modo:
ssh the-server
Last login: Mon Feb 8 18:54:36 2016 from my-laptop.company.com
me@the-server$
last -w | grep "$USER" | head -n1 | perl -lane 'END{print "Last login: @F[3..6] $F[8] from $F[2]"}'
perchélastlog
stavo troncando il mio nome host.
