well edit /etc/passwd na instaed of /bin/sh(ksh, bsah) give them /bin/nologin

it means after connection no shell is run, so they cannot workin with system using telnet or ssh

Shalom hangyu,

Set the shell to /usr/bin/false or /usr/bin/nologin.

Make sure these are defined in /etc/shells

Just to add that you can assign the shell upon user creation with:
useradd -s /sbin/nologin username

or change the shell for existing user with:
usermod -s /sbin/nologin username

The above mentioned is a good practice.
