after weeks of confusions.. finally i understand how to setup the network access from windows to ubuntu.
first u have to understand that the ubuntu define with the uniqe username.
after you have the username, one or two it doesnt matter, u have to create a samba password.
ah yeah, this command would only work if you install the samba first. and also the smbfs to change the cifs if necessary.
#useradd budi
then fill in the unix password to access it later and also other information stuff
#smbpasswd -a budi
enter the password
this samba password will be use by other system to log in to. well i have tried it with my vista and its working.
that’s all what all the things do.
