Configuring the telned daemon on Gentoo to work with root

Gentoo will not come with a telnetd preinstalled, if you want to login with a telnet to your Gentoo box you could follow these step (running as root user):

• Install the xinetd internet superserver daemon:

# emerge sys-apps/xinetd

• Wait for the end of the emerge step
• Edit /etc/xinetd.conf configuration file to permit outside logins:

#

# This is the master xinetd configuration file. Settings in the

# default section will be inherited by all service configurations

# unless explicitly overridden in the service configuration. See

# xinetd.conf in the man pages for a more detailed explanation of

# these attributes.




defaults

{

# The next two items are intended to be a quick access place to

# temporarily enable or disable services.

#

#       enabled         =

#       disabled        =




# Define general logging characteristics.

        log_type        = SYSLOG daemon info

        log_on_failure  = HOST

        log_on_success  = PID HOST DURATION EXIT




# Define access restriction defaults

#

#       no_access       =

#       only_from       =

#       max_load        = 0

        cps             = 50 10

        instances       = 50

        per_source      = 10




# Address and networking defaults

#

#       bind            =

#       mdns            = yes

        v6only          = no




# setup environmental attributes

#

#       passenv         =

        groups          = yes

        umask           = 002




# Generally, banners are not used. This sets up their global defaults

#

#       banner          =

#       banner_fail     =

#       banner_success  =

}

includedir /etc/xinetd.d

• Install the telnetd server daemon

 

# emerge netkit-telnetd

 

• Configure the telnetd daemon editing the /etc/xinetd.d/telnetd file

 

service telnet

{

        flags           = REUSE

        socket_type     = stream

        wait            = no

        user            = root

        server          = /usr/sbin/in.telnetd

        log_on_failure += USERID

        disable         = no

}

• Restart the internet superserver daemon

# /etc/init.d/xinetd restart

• Add the telnetd daemon as startup daemon

# rc-update add xinetd default

• To give the possibility to login as root trough a telnet you shall modify the /etc/securetty configuration file:

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