    Hi!,

    Running a Suse8 box.

    Security makes it so that a root account cannot use telnet to connect to my machine you have to login as "root" locally or with SSH. I understand why with unencryped p/w's being sent with telnet over a network however i dont care about the security i want to know if anyone knows how to allow root to telnet to my machine.
    Any help appreciated
    Spartic

    Applies to

    SuSE Linux: Version 8.0

    Situation

    You want to log in as root to your SuSE Linux 8.0 via telnet.
    Procedure

    Edit the file
    /etc/pam.d/login

    and disable the line
    auth required pam_securetty.so
    Warning

    Never use telnet for remote applications, since the whole data exchange takes place in an unencrypted way. Even your login (password) is transmitted unencrypted on the network. Telnet involves a high security risk. Thefore, we recommend you to use encrypted tools such as OpenSSH, for which Windows and MacOS clients are also available. You can find more information on this program at OpenSSH.org

    Don't use telnet to login as root.

    Instead just allow root ssh logins, but, preferably

    ssh into your box as a 'normal' user.
    then su to root.

    Don't do what Donnie don't does.

    However:

    edit this file:

    /etc/securetty

    add entries like the following

    pts/1
    pts/2
    pts/3
    pts/....etc

    It's just a matter of good protocol not to use telnet full stop. (remove the telnetd and/or comment it out in /etc/inetd.conf)

    And as mentioned, preferably you should ssh to a user a/c and then su to root. The only real reason I'd see for ssh'ing directly to root would be in a case where you felt that your user a/c may have been comprimised, etc.

    As for telnet to root ... just a bad habit you're better off avoiding.
