Hi to All,

I want to allow root login thru telnet in my PC. This is just used to do testing and learning. So there is no worry of security being compromised. I just dont seem to find it.

I am sure we can allow root logins thru telnet.

Sorry,

After posting here, I Googled and found that what I was doing was right.

I knew that inserting an entry for pts/1 ........... to pts/n into the file /etc/securetty will allow root login.

But the mistake I did was that I just inserted only one line, pts/1, from an xterm. Unfortunately, when I tried to telnet to localhost, it used to get pts/2 or pts/3 and it used to fail. And I thought something else will have to be enabled.

After Googling, I realised that this is the only way and I immediately put in entries for more pts....and it worked.

It is also importat to note that you need to modify /etc/pam.d/login pam config file. Remove line auth required pam_securetty.so and you should be able to login as root user over ssh.

Code:

vi /etc/pam.d/login

Comment it out (or remove0 following line

Code:

#auth       required     pam_securetty.so

Once you save these changes, you should be able to telnet to your system as the root user

Here is my sample file:

Code:

#auth       required     pam_securetty.so
auth       required     pam_stack.so service=system-auth
auth       required     pam_nologin.so
account    required     pam_stack.so service=system-auth
password   required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth
session    optional     pam_console.so

don't forget to restart xinetd after editing /etc/pam.d/login

another method is to remove securetty
ex:
-bash-3.00# rm -f /etc/securetty
-bash-3.00# /etc/init.d/xinetd restart

root can now login thru telnet. securetty will just be created after reboot.
