Telnet through Internet - SCO

Hi all, I need to setup the SCO Unix Openserver Enterprise 5.0.6 server can be accessed through internet. I have a fixed IP address and also set the router port 23 direct to the unix server IP address. However I still cannot telnet to the unix through the internet, but can be telnet locally. Should I do some setup in the SCO Server? Rgs, Man...

    Default Telnet through Internet

    Hi all,

    I need to setup the SCO Unix Openserver Enterprise 5.0.6 server can be
    accessed through internet. I have a fixed IP address and also set the router
    port 23 direct to the unix server IP address.
    However I still cannot telnet to the unix through the internet, but can be
    telnet locally.

    Should I do some setup in the SCO Server?

    Rgs,

    Man

    Hello,
     

    You want your server to be accessible via telnet to the whole internet?
    You're a really dangerseeker! Go, do yourself a favor and install OpenSSH.
     

    No, but perhaps some network security workshops.

    Man, can you ping it over the 'Net?

    you are missing the default gateway:
    /etc/rc2.d/S99route should read:
    route add default <your router's ip>

    Also, add the router to the /etc/hosts file.
    192.168.1.1 router
    will suffice. That will eliminate the long login delay as OSR5 does a
    reverse DNS lookup on the source IP of the telnet session, in this
    case, the router.

    I would look into using SSH (secure shell) instead of telnet as the
    telnet logins, passwords, and traffic are sniffable.

    Where can I download the Open SSh from ? Do I have to reboot the machine
    after installation (relink kernel) ? How do I know if it's already installed
    ? SCO 5.0.5

    Thanks

    you can get the sources from www.openssh.org. Of course you need a development
    system on your machine to compile the thing. Don't know if there any binaries
    around. If all else fails, gimme a mail and I can provide you with a binary
    compiled on SCO 5.0.5 with gcc 3.3.1.

    And no, you don't have to reboot to activate sshd.
     

    You don't have to relink the kernel.
     

    check if the command 'ssh' is in user-$PATH and 'sshd' is in
    root-$PATH

    There's a complete binary suite of OpenSSH at ftp.jpr.com.

    Won't work. You can't ping an inside computah on a private IP through
    a router configured for NAT from the internet unless you also
    configure the router to redirect all ICMP packets to that inside
    computah. This is a fairly bad idea for security purposes. You could
    ping the router from the internet, but that won't help with the
    problem.
