Você tem mount.cifs
instalado em seu sistema? Do Guia do usuário do CIFS :
Once the CIFS VFS support is built into the kernel or installed as a module (cifs.o), you can use mount syntax like the following to access Samba or Windows servers:
mount -t cifs //9.53.216.11/e$ /mnt -o user=myname,pass=mypassword
If the mount helper, mount.cifs, is installed (which is usually the case for most Linux distributions), then a tcp host name rather than ip address may be used. For example,
mount -t cifs //my_server/e$ /mnt -o user=myname,pass=mypassword
