Hi all
I am new to Linux, have used KDE/SLAX before but am now attempting to use linux on my old computer to accomplish these objectives:

1) Run an FTP so I (& my mates) can access files anywhere wit ease(no dramas).
2) Enable sharing of my drives so I can put files from Laptop into this computer

Now I have successfully Installed Ubuntu Server (Finallllly) but then messed up cuz I installed the Gnome GUI and now cant find any place where I can type any sudo commands. vsftpd should work for me right??
Can I just uninstall Gnome?? Alt-F2 --> "gnome terminal" doesn't work

Any help would be really appreciated. thanks

P.S I didn't get much help at servers so em here
