What are pseudo-tty devices? can any body guide me guide or tutorial where all the devices are listed with their use?
The reason for posting the thread is i m doing server hardening .It is not recommended to include pseudo-tty devices in /etc/securetty file .
Following are the statement from hardening guide.
This file should only contain locally attached console devices, and must not contain any pseudo-tty devices
Correct me if i m wrong.
locally attached console devices which are normally determined using w command.
For example .
These ttys can be taken by physically logging in to machine and using (alt+f1-f6).Therefore we can have upto 6 local tty devices.
Are they begins with p.
following is a content from my /etc/securetty.
# cat /etc/securetty
