hi! I m again asking the same question about hackers and open ports. I usually wonder how one could break in my system if he/she knows my ip address and i've some ports open at a LAN in which windows 98 OS is installed. Note that i m sure i've no trojan's server installed (like subseven) Than i came to know about one method of connecting to host system using opened shared ports. It was uploading other ip and port in lmhost file. Well i want to know about validity of this method if this really work or just a rumour. Due to some reasons I can't install any firewall and in this case upgrading to win2000 pro can save me from such attacks? Again telling i m now using win98 home networking on both workstations and server system.
