The command to figure out what shares are available e.g. on the computer 192.168.0.2 type:
For nfs: /usr/sbin/showmount -e 192.168.0.2
For samba: smbclient -L 192.168.0.2
Since I always use some GUIs, I don't really remember anymore how to connect to a Windows machine via the command line. smbclient -L windowshost shows you the shares that are available. Often, you you cannot browse them without a login/password for that windows machine, therefore you need to type smbclient -L windowshost -U username And occasionally the netbios name doesn't work either and you need to replace it by the IP address.
