Hi there,

Due to limited resource available in my network, I had to allow users comming from internet to telnet my SCO UNIXWARE box directly, like:

telnet 23.1.1.2, anyone can access. I can't make it secure based on IP addresses or hostnames since IP address is dynamic. I have made all the passwords secure but still there is a risk of system hack thru telnet port. Any one can suggest me the way to improve my security with the resources available.

Regards,
Tayyab
