RHEL: Enabling standard ftp/telnet

# Tested on RHEL 5

# By default system is as secured as to be accesible only via ssh/sftp.


# Enabling ftp
# ------------------------------------------------------------------------------------------

# 1.- Edit File /etc/xinetd.d/gssftp and change following line:

# from

   disable = yes

# to

   disable = no

# This modification can be carried out by issuing 'chkconfig' command too:

chkconfig gssftp [ on | off ]


# In the same file, replace this line:

   server_args = -l -a

# by

   server_args = -l



# 2.- Reiniciar el demonio xinetd

/etc/init.d/xinetd restart

# or

service xinetd restart

# or

skill -HUP xinetd

# or

kill -HUP <xinetd_PID>




# Enabling telnet
# ------------------------------------------------------------------------------------------

# 1.- If not installed, install a telnet server, for instance telnet-server-0.17-39.el5


# 2.- Disable (if enabled) kerberos telnet service and enabled the new one:

chkconfig krb5-telnet off
chkconfig ekrb5-telnet off

chkconfig telnet on

chkconfig --list | grep -i telnet
   ekrb5-telnet:   off
   krb5-telnet:    off
   telnet:         off


# 3.- Edit /etc/securetty file and add new access for pts connections:
[...]
    pts/0
    pts/1
    pts/2
    pts/3
    pts/4
    pts/5
    pts/6
    pts/7
    pts/8
    pts/9
    pts/10
    pts/11

# 4.- Restart xinetd daemon

/etc/init.d/xinetd restart

# or

service xinetd restart

# or

skill -HUP xinetd

# or

kill -HUP xinetd


# 5.- In case of access problems, comment out following line in /etc/pam.d/login file:

   auth required pam_securetty.so

# and restart xinetd daemon



# Note: Take into account that it may be necessary to adjust conveniently iptables subsystem.
#       In addition to this, on RHEL 6, if active, we'll have to adjust SELinux configuration.
