Samba without Password

vim /etc/samba/smb.conf

Change it to :>

# security = user
security = share

also remove the semicolon from the below line.

guest account = nobody
[ABCProject]
guest ok = yes
guest only = yes
path = /Path to ABC Project
read only = yes
browseable = yes

[Share name]
writable = yes
path = /path/to/directory
public = yes
guest ok = yes
guest only = yes
guest account = nobody
browsable = yes

save and exit
:wq

/etc/init.d/samba restart

that's all.
