I cannot open system-config-samba

If you want to share folders using Samba then use the right click menu in nautilus. It's a lot easier

I do not want to share folders, I want to view shared folders from ubuntu on a windows 7 machine

Then use:

File -> connect to server

Or in Dash type:

\\servername\sharename

You will obviously need your Windows username and password to authenticate as.

Once you get access, you can add the location to nautilus favourites using the top right cog on nautilus itself. This gives easy access. Obviously store your credentials to make things super easy

Ok, can you tell me please where do I get servername and sharename,

http://www.liberiangeek.net/2011/10/filesharing-between-windows-and-ubuntu-11-10-oneiric-ocelot/
this is the tutorial I tried to use

The server name is the name of the Windows PC and the share name YOU have set when you shared a folder in the Windows OS. How can you connect to a share if you don't know this stuff?

Well it just will not connect, that is why I am asking

Your problem might be caused by wrong values in the samba configuration file.

Please provide the output of the following commands:

It seems that lines 149 and 150 of /etc/samba/smb.conf do not contain a value for the items. Maybe this is causing problems.

Try the following:

open a terminal and issue the command
gksudo gksudo gedit /etc/samba/smb.conf
Provide your password when asked so, and an editor with your samba config file will open.
Scroll down to line 149 and put a '#' character in front of the two lines

lpq command =
lprm command =

making them

# lpq command =
# lprm command =

Save the file and close the editor, and then try running system-config-samba again.

No it did not work, thank you for your answer, but I still need help

I just see that the error must be line 117 and/or 118

   117 valid users = Ignoring unknown parameter "update encrypted"
   118 , root, smbguest

Edit smb.conf as described before, but put a # character at the beginning of line 118,
(you might as well undo the previous change) and try again.

Did it, still it does not work, thank you for your time, but still I need an answer thank you again

I am quite sure that the traceback in your problem report indicates a syntactical error in the samba config file.

Please try again:

1. execute "system-config-samba --debug" from a terminal
2. execute "cat -n /etc/samba/smb.conf"
3. copy/paste all output into this question document

There is still the syntax error in lines 117/118

Put a '#' sign also at the beginning of line 118 making it

#valid users = Ignoring unknown parameter "update encrypted"
#, root, smbguest

finnaly that helped, I could open the configuration gui, however, I could not connect to my windows machine, I guess I shall open another topic

Maybe you have to use admin privileges for system-config-samba to have an effect, try

sudo system-config-samba
