Hello, with your help, I finally setup my RH7 linux box onto a large WinNT LAN. They just give me a dynamic IP address. Now I can ping and connect by name the WinNT computers and they can also do the same thing to my computer (samba & nss_wins). I wrote a simple C program that hack the IP address and put it into my /etc/hosts file every time the computer reboots. I don't know if this thing help somehow. I can send e-mail from my computer to everywhere in the company domain (romtelecom.ro) but I cannot receive e-mail fom that domain. Is there any trick to setup sendmail or something else in order to send and receive e-mail outside the company domain? Maybe I can use the company mail server as a relay.!! ???
