Samba Gruop rettigheder

Der er nok en der læser til IT-Supporter? *G*

ja, mem det har ikke noget med skolen at gører

Hvis du vil bruge en allerede eksisterende Redhat bruger, skriver du bare
smbpasswd <bruger>
og giv brugeren et smbpassword
Ved denne løsning overfører du brugerens linux rettigheder til smb.
Dvs. hvis du har lavet grupper mv. som nogle bruger er medlem af, for at have rettigheder til bestemte biblioteker mv., så gælder samme regler i samba.

smb.conf eksembel på 2 shares

[Bogholderi]
  path = /home/bogholderi/
  valid users = <bruger1> <bruger2> osv.... (med mellemrum)
  public = no
  writeable = yes/no

[Salg]
  path = /home/salg/
  valid users = <bruger1> <bruger2> osv.... (med mellemrum)
  public = no
  writeable = yes/no

Ups, glemte grupperne:

usermod -G <gruppe> <bruger>

Ved denne kommando bliver Linux brugeren tilføjet til den gruppe du har angivet. Han forbliver samtidig medlem af sin egen gruppe.

Du opretter en group med
groupadd <gruppe>

Derudover er der 2 kommandoer man bruger til at ændre ejeregenskaber og attributer, de hedder chown og chmod.
Læs mere ved at skrive:
man chown
man chmod

NOTE! For every user there is, the nmb service (auto starts with the smb service) 1 MB ram is used

Test have been made linux samba vs W2K server, Samba linux is proven faster that MS.. (could be samba and ext3 reiser filesystem)

step 1.1 Install samba

Download the latest approved samba.rpm and sambacommon.rpm  version
install samba type rpm -i [filename.rpm]. or -U to update if samba is already installed
Type service smb start --> now smb and nmb services will start.
everytime you make changes in the /etc/samba/smb.conf file you'll have to restart the smb. service (type service smb restart).


step 1.2 Create unix users

type useradd [username]
type passwd [username created in step1.2.(1)
enter password


step 1.3 Create samba users

smbpasswd -a [username]
enter password

NOTE! to delete a user edit etc/passwd

step1.4 Create unix group(s)

groupadd opr cht etc...

step 1.5 Put the unix users in the group

edit etc/groups,,,,, find ex. opr group and write usernames seperated by a comma . ex. all:cmj,jjc,cbb    etc.....

step 1.6 create the shares folders ex. operation, chartering etc.

run the mc (midnight commander) type mc and hit enter.
goto the /home and hit F7
type the sharename     ex. operation, all, chartering, it, install (use the standard see link )
test the access rights type ll -a in the directory folder
Change the access rights so it is controlled on groups level (stand above the folder (/home))
changemod on the new directories type chmod 775 [foldername]
Change the ownership  type changeown root:[groupname] /home/[foldername]/ -R
Rest of the sequrity is controlled in etc/samba/smb.conf.

1 = X  (execute rights)
2 = W (write rights)
4 = R  (read rights) 

type ll -a to see directory/folder/file rights  ex. stand above operations folder and type ll -a  (you'll see rights for owner:group:others    rwxr)

So 775 is rwx by owner, rwx by group, and rw by others..okay!

step 1.7 add the pc to the smb domain

type useradd -r -g [group ex. all] -d /dev/null -s /dev/null MASHINENAME$         (ex CMJPC$)
smbpasswd -a -m [MASHINENAME] (ex. CMJPC)


step 1.8 edit the smb.conf pdc to the following standard



#======================= Global Settings =====================================
[global]

# workgroup = NT-Domain-Name or Workgroup-Name
  workgroup = [domain name] ex. CDA

# server string is the equivalent of the NT Description field
  server string = Samba Server

  netbios name = [servername] ex. CDA02
 
# This option is important for security. It allows you to restrict
# connections to machines which are on your local network. The
# following example restricts access to two C class networks and
# the "loopback" interface. For more examples of the syntax see
