logging in problems

[NewToo]

Hello

Again I'm new at this!


I'm having issue logging in to my linux server using telnet as root user. The server let me login with the account that i created but doesn't let me login as root. I'm using linux redhat 7.3.


Thank you for all you're help

That is more than likely a default security feature. To be secure it is best NOT to be able to remotely login to a box as root, you should login first as a regular user and the 'su -' to root. If you are able to telnet as root your system is more susceptible to crackers who have cracked your root password. I would suggest not changing this feature.

Thank you!

So after I login as a user i can just type su to change to root user...then it will prompt me for the password?

Thank you

By default telnetd does not allow root to login. You can change this, but I wouldn't reccomend it and forgot how anyway (someone else know?).

You can connect as yourself, then type 'su', enter the root password and become root. Or better yet, configure sudo so you can run tall commands without having to be root all the time.

Don't forget that telnet sends passwords across the wire as plaintext, ssh is a good alternative as the whole connection is encrypted.

Have fun!

Well, once you've verified it's on your box (just type "which sshd" if it shows the path to sshd (something like /sbin/sshd or such)) then just type AS ROOT "service sshd start" and it's going. If it's not on your system go to

http://www.openssh.org

and get the tarball for the latest version untar it and READ THE INSTALL file and follow the install instructions. Meekness: Uncommon patience in planning a revenge that is worth while.

Hi,

If you really want to login as root, add an entry in /etc/securetty for the line from which you want to connect. But as d3funct and verland said, it's "more than likely a default security feature" ...
