Telnet, rlogin and other network services

This sectino discusses:

rpm -iv xinetd*rpm

You can configure which services are enabled one of two ways:

Start-->System Settings-->Server Settings-->Services, which brings up a Service Configuration window: which is described The Official Red Hat Linux Customization Guide, Chapter 14. Controlling Access to Services.
Or make modifications to files (described below). Each file in the directory /etc/xinetd.d controls a different service.
For example, if you would like to enable the telnet service, you would need to modify the /etc/xinetd.d/telnet file. If the file //etc/xinetd.d/telnet does not exist on your machine, then get the telnet server software from the Red Hat CD or download the telnet server. Then install the telnet server:
```
rpm -iv telnet-server*rpm
```
Then enable the telnet server by changing the /etc/xinetd.d/telnet file. Change the disable=yes line to disable=no. For example, /etc/xinetd.d/telnet should be changed to:
```
# /etc/xinetd.d/telnet
service telnet
{
    flags           = REUSE
    socket_type     = stream
    wait            = no
    user            = root
    server          = /usr/sbin/in.telnetd
    log_on_failure  += USERID
    disable         = no
}
```
After changing this file, send a HUP signal to xinetd:
```
killall -HUP xinetd
```

Problem	Solution
The /etc/xinetd.d directory doesn't exist.	Get the xinetd package and install it.
The /etc/xinetd.d/telnet file doesn't exist.	Get the telnet-server package and install it.
The /etc/xinetd.d/rsh (for rlogin) file doesn't exist.	Get the rsh-server package and install it.
I can't telnet or rlogin as root.	edit /etc/pam.d/login Insert a # at the beginning of the following line: auth required /lib/security/pam_securetty.so
