If you are getting permission denied when connecting to a new share, one common cause of this is that samba does not have access to Linux user passwords by default. Samba is an implementation of the SMB/CIFS protocol for Unix systems, providing support for cross-platform file and printer sharing with Microsoft Windows, OS X, and other Unix. samba SMB/CIFS file, print, and login server for Unix. Winbind enables Linux to be a full member in Windows domains and to use Windows user and group accounts on Linux. domain logons = yes # if you enable domain logons then you may want a per-machine or # per user logon script # run a specific logon batch file per workstation (machine) logon script = %m.bat # run a specific logon batch file per username logon script = %U.bat # Where to store roving profiles (only for Win95 and WinNT) # %L substitutes for. (gedit:2349): Gtk-WARNING **: cannot open display: :0īefore Wayland, running GUI applications with elevated privileges could be properly implemented by creating a Polkit policy, or more dangerously done by running the command in a terminal by prepending the command with sudo but under (X)Wayland this does not work anymore as the default has been made to only allow the user who started the X server to connect clients to it (see the bug report and the upstream commits it refers to).Ī more versatile though more insecure workaround allows any graphical application to be run as root #Using xhost. Unable to init server: Could not connect: Connection refused GParted or Gedit), will fail with an error similar to this: Trying to run a graphical application as root via su, sudo or pkexec in a Wayland session (e.g. Where appname is the name of the particular app. # XAUTHORITY=/home/ username/.Xauthority appname This will permanently allow root to connect to a non-root user's X server. etc/profile export XAUTHORITY=/home/ username/.Xauthority Then switch to your root user using su or su. To both /etc/pam.d/su and /etc/pam.d/su-l. Permanently allow root access Method 1: Add the line session optional pam_xauth.so Xhost can be used to temporarily allow root access. If you are behind a firewall, you may consider them to be safe enough for your requirements. These methods will allow root to connect to a non-root user's X server, but present varying levels of security risks, especially if you run ssh. sux AUR (wrapper around su which will transfer your X credentials).These methods wrap the application in an elevation framework and drop the acquired privileges once it exits: This may be the object of a bug report to the upstream project. Applications should rather "defer the privileged operations to an auditable, self-contained, minimal piece of code that gets executed after doing a privilege escalation, and gets dropped when not needed". This should however "only be used for legacy programs", as pkexec(1) reminds. The proper, recommended way to run GUI applications under X with elevated privileges is to create a Polkit policy, as shown in this forum post. There are multiple ways of allowing root to do so however, if necessary. Xorgīy default, and for security reasons, root will be unable to connect to a non-root user's X server. The same effect can be attained via the Other locations server address bar. in nautilus or gedit, type Ctrl+l and then prepend the admin:// scheme to the resource path. Tip: This can also be done from the application location bar/file selector: e.g. Īvoid running graphical applications as root if possible, see #Circumvent running graphical applications as root.Ĭircumvent running graphical applications as root sudoeditĪccess to privileged files and directories is possible through GVFS by specifying the admin backend in the URI scheme, e.g.: You are opening up a massive, gaping security hole. By running GUI applications as an admin user you are literally running millions of lines of code that have not been audited properly to run under elevated privileges you are also running code that will touch files inside your $HOME and may change their ownership on the file system connect, via IPC, to even more running code, etc. there are no *real*, substantiated, technological reasons why anybody should run a GUI application as root. As described by Emmanuele Bassi, a GNOME developer: Warning: All of the following methods have security implications that users should be aware of.
