I got a job from a friend of a family fixing an office network.

When I saw their server was a linux command line OS, I felt pretty dumb. I thought most Linux was graphic, shows what I know, hahah.

Anyways I'm starting to learn Linux to fix their email and ftp program from a person I knew. But his gone so I have to figure out evreyone on my own now.

Basically I think its redhat, and he's using samba for the email and ftp program. He gave me this info to create accounts.
as root, do
adduser username
passwd username
smbadduser username:windows_login_name
where the username would usually be firstinitialLastname and
windows_login_name is usually their first name
smbpasswd [new password]

The samba config files end up in /etc/samba. Have to do
/etc/rc.d/init.d/smb restart to restart the windows fileserving.

So now I'm wondering is there a good internet guide for using samba (haven't found one yet)?

Is samba doing both the filesharing and email program?

They can log on to the email server with in the POP3 and SMTP while on the network, but they are having problems with the servername.com server made to download off the internet. What could cause this and how can I fix it? Shoudln't they be able to have the servername.com in the POP3 and SMTP while on the network as well as the internet, and work for both?

And any other advice you guys could offer.

Thanks guys.
