How to enable telnet server for both IPv4 and IPv6 in Fedora core 16!

To enable Telnet Server please follow below steps :

Fedora core 16 Server as telnet server:

1) yum install telnet-server

2) vim /etc/xinetd.d/telnet

service telnet
       disable = no
       flags           = REUSE
       socket_type     = stream
       wait            = no
       user            = root
       server          = /usr/sbin/in.telnetd
       log_on_failure  += USERID
        flags = IPv6

Change disable to "no" and add "flags=IPv6"

3) systemctl restart xinetd.service

Fedora Core 11 Client

 telnet  ipv6address%interface-name

Telnet clients supports ipv6 but if you do not specify interface-name in the command , "invalid argument" error will be displayed in clients, when you try to telnet.

telnet fe80::1e63:45ff:fec4:8823%eth1


telnet ipv4-address


Both command should work fine.
