Hello everybody!
I would like to block an IP address from having access to my shared files,
Could someone tell me the line I have to put to the smb.conf in order to prevent a computer with a certain IP to connect to samba and have access t my shared files?

Thank you in advance

just put a line in the global options for smb.conf, saying "hosts deny = a.b.c.d" and restart samba.

I would sugjest getting deeper into the power of Samba.

Try doing this;

Under [global]
find security and change it to;
security = user

then go down to Share Definitions and insert this;
[homes]
comment = Home Directories
browseable = no
writable = yes

[Profiles]
path = /%G/%U/.profile
writable = yes
browseable = no
guest ok = yes
directory mask = 0755
create mask = 0755
read only = no

comment = share
path = /home/samba/share
valid users= kenny, otheruser
public = yes
writable = yes
printable = no
create mask = 0777
directory mask = 0777
browseable = yes

Restart Samba. Don't forget to change the varibles that are in mine to suit your needs. Also make sure that you create the samba users on the server in order to get the user based security to work.

Regards

hmm. thanx but I will have to know what does every line do before use it..
Thank you very much!

Sorry if I wasn't that detailed on what these do. But here you go.
****************************************************
This will make it so in order to connect to the Samba server, it will prompt you for a username and password.
****************************************************
Under [global]
find security and change it to;
security = user

*************************************************
This will tell samba to direct the user to their home directory.
*************************************************
then go down to Share Definitions and insert this;
[homes]
comment = Home Directories
browseable = no
writable = yes

[Profiles]
path = /%G/%U/.profile
writable = yes
browseable = no
guest ok = yes
directory mask = 0755
create mask = 0755
read only = no

**************************************************
This will add additional share directories and also you can say which user cann access this directory.
*************************************************

comment = share
path = /home/samba/share
valid users= kenny, otheruser
public = yes
writable = yes
printable = no
create mask = 0777
directory mask = 0777
browseable = yes


I hope this clears it up for you.

Regards
