Hello. Please help.

1. How will i know who are the authorized windows pc users that can access the folder shared from a linux server-samba? how to display list of them? what command? I am struggling through ssh only..
2. How will i change their access rights to the folder? if i only want them to access the file as read-only, or write or read and write???
(i am trying to configure this linux server using PUTTY or SSH only)
Thank you.

Both questions can not be answered without more knowlegde about your system. But you can check the /etc/samba directory and look in the smb.conf file. Here you can allow and deny certain users/ip-adresses.

EXAMPLE

[global]
debuglevel = 1
workgroup = Workgroup
netbios name = OURFILESERVER
security = share
disable spoolss = Yes
show add printer wizard = No
printing = cups
load printers = yes
hosts allow = 127.0.0.1 192.168.1.0/24 192.168.1.110 78.206.93.2 72.163.17.253
hosts deny = 0.0.0.0/0

[specialdocuments]
comment = Specails
path = /var/specialdocuments
read only = No
guest ok = yes


[readonlydocuments]
comment = olddata
path = /var/olddata
read only = Yes
guest ok = yes

In the smb.conf check for the entry of file which has been shared

change the options as per your requirements

for permissions on individual folders
give related permissions using

@sswuste: Thanks for your reply. Now i understand the concept on how to set those permissions..

@deep27ak: Thank you also for your answer. But where should i put this???

Code:
#chmod 755 (dir_name)


Let us say i have to share those individual folders with it subfolders in diff access combination (read, write, read and write). In what portion should i put this code??? How does it affect the permission for each user??? Thanks

It is all clear now. Sorry if i have to ask you without even searching the net.Thank you very much!
