Testing Services:

C:\>telnet 192.168.19.130

Red Hat Enterprise Linux Server release 5.1 (tikanga)

Kernel 2.6.18-53.el5 on an i686

Login

Note that if you install the system, you need a firewall.

# iptables-f # Turn off the firewall

To remotely telnet to the server

the limit that Telnet cannot log in directly with root :

Login

Enter the user name rootin login:and enter the appropriate password, but return the login error message

Login Incorrect

This is because although the telnet service is turned on, Linux does not allow root to be telnet by default Log in, we Let the system allow root login by changing the/etc/securetty file

Change /etc/securetty to allow root to log in to the system

Look at the cat/etc/securettyfirst, the content of the file is roughly

Console

Vc/1

Vc/2

Vc/3

Vc/4

Vc/5

Vc/6

Vc/7

Vc/8

Vc/9

Vc/10

Vc/11

Tty1

Tty2

Tty3

Tty4

Tty5

Tty6

Tty7

Tty8

Tty9

Tty10

Tty11

We then use the following instructions to add content to this file

echo "pts/0" >>/etc/securetty

echo "PTS/1" >>/etc/securetty

cat/etc/securetty This file again, there will be two more lines in the back .

......

pts/0

Pts/1

At this point we can log in with root
