If you are a real newby like me !! you may have been looking for config files here and there, making a few changes , that didnt work !!
I have found a very good tool called WEBMIN, its seems really good i can set my system up for samba, apache, dhcp, user admin, group admin - just about everything and you do the lot from your web browser. I have found this tool really good as it not only points you to the files you would like to know how to change via Term but it also makes the changes so you can have a look and see how its done and what commands you missed out when you tried to do it !blind! This tool works for just about every flavour of unix going - its well worth a look for newby's
