Enable telnet for root

Post by Spidomh » 2014/08/29 14:39:03

Hi,

I have a freshly unstalled Centos7 server and i need to permit telnet login for root.
I tried to install telnet-server and xinetd, but I can't figure out how to configure it to give access to root via telnet.
:(
Any suggestion?

Hi Gerald,

thank you I could install telnet and it works!! :D

Anyway I need to enable root access via telnet, when I try to connect as root I receive a Login Incorrect message back.

Can you help me?

It is better to login as a regular user and then su root.
If you really must telnet in as root, add telnet to /etc/securetty

I haven't seen anyone else say this so... using telnet is a huge security risk. It's an out dated protocol that doesn't encrypt data and all usernames and passwords are visible in plain text as they go over the network. Anyone can sniff this data and compromise your system. It should not be used.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Thank you a lot again, all is now perfectly working.

You're right Trevor, anyway this will be an internal server for testing and development and I'm been required to allow telnet for root ... customer is ever right
