Unable to set up Samba client

I am trying to set up Samba using the instructions at https://wiki.alienbase.nl/doku.php?id=slackware:samba

I think that I have the server set up ok but I am having difficulty with the client side

The mount command
Quote:

mount -t cifs //192.168.0.1/public /mnt/samba/bob/public -o rw,uid=0,gid=10,fmask=664,dmask=775 -U <some_special_user>

fails with Quote:

mount: bad usage

I have tried simplifying things to
Quote:

mount -v -t cifs //192.168.1.51/smbguest /mnt/samba/alan or mount -v -t cifs //192.168.1.51/alan /mnt/samba/alan

but these give me
Quote:

mount error(13): Permission denied

What am i doing wrong?
