LinuxQuestions.org - Cannot conect to the internet. ¿dhclient?

Hi

I've asked similar questions in the last few days, but i think that finally -or so i hope- i'm beggining to understand what my problems is. And please, don't laught :). I have four CPUs, three of them runing W, and a forth running Slackware 9.1 wich i installed last week :). I have two problems, wich i think should be threated differently:

i.- I want to connect to the internet (So i can finally download octave!). I have a Realteck RTL8019 card. The four computers and my cable conection are conected through a HUB. Using the command network on the installation the only controler wich worked was dummy. then i runned ifconfig dummy0 up. To check that i can conect with something i typed ping 127.0.0.1, and got a series of messages like: 64 bytes from.... until Ctrl-C. So, i believe my card is working. From what I've read on the manuals, i believe i should now use dhclient. When i run dhclient dummy0 i get: dummy0: not found. it could be (that has to be a problem) that my dhclient.conf file is empty... ¿how do i configure it? Maybe i'm on the wrong track all along... is this the correct way to setup an internet conection?

ii.- I want to connect to my LAN. I believe that samba is the right tool. I made a smb.conf file from the smb.conf - sample file, some manuals and http://hr.uoregon.edu/davidrl/samba-unofficial.html. but i have no idea about how to acces the files on the other machines! do i have to mount them (if so, how)?

I've made some questions to the forum in the past, some not well asked some with very helpfull answers. I'm a newbie eager to learn, but need to get this done before i start classes again!

Thanks a lot.
