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

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.

> How do I know if it's already installed ? SCO 5.0.5

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.
