Remote Login (Unix)

Is there any way I can disallow remote login on a m/c

Yes, it is possible to disable remote logins.

What type of remote logins do you want to disable, ssh,telnet,rsh etc?

With ssh you can allow/disallow user logins vi the sshd_config file, telnet and rsh can be controlled via tcpwrappers or xinetd.

The first step in blocking remote logins is also one of the first steps everyone should do after bringing up a new server:

(1) Edit the /etc/inetd.conf file and comment out all services you will not immediately need;

(2) Examples (for me) include all the r* commands, finger, etc.

This is critical for security and is just a good practice. Don't leave these services running unless you actively use them.

I have one doubt though
In TCP_Wrappers it uses the /etc/hosts.allow and hosts.deny files for logging in. Can the hosts specified be m/cs other than UNIX .
