Basic linux commands
 

I know that in MSDOS to see what a computer is sharing i use
nbtstat -a
And if i want to connect i can use
net use

In linux what is something that is like nbtstat....how do i view what a computer is sharing?

maybe you can use smbmount

If you're "sharing" in the sense of Samba, then smbmount is probably what you're looking for. Otherwise, if you want to share using more traditional methods (i.e ftp, or my fav.: sftp), then you'd setup what directories a user can access in the server's configuration. It all just depends.

i want to be able to see what a differnt computer is shareing

Try using smbclient -L <hostname>

That should give you a list of all SMB shares on that PC...

thank you

nmblookup -A ip
