smbfs filesystem not supported by the kernel - How to add it?

[mmaciej]

I've tried to mount samba share whit this command and I've got an error:
mount -t smbfs //servername/share /mnt/share

ERROR: smbfs filesystem not supported by the kernel
Please refer to the smbmnt(8) manual page
smbmnt failed:255

I've also tried:
modprobe smbfs - with result:
FATAL: Module smbfs not found

What else can I do?
What did I do wrong?

use cifs instead. Linux is moring away from smb and moving to cifs.

Check out mount.cifs command
