If step 5 outputs anything other than localhost:xx.0, then your remote configuration is overriding theĭISPLAY environment variable set by sshd on the remote side. In thisĬase, you must fix the configuration on the remote side. If step 5 does not output anything, then step 6’s results probably include X11Forwarding no. If you get any other messages: use ‘ssh -vvv -X remote’ to obtain more information. If you get any messages about ‘xauth’: see above. Step 4 should not return any error or warning messages. It is probably a commercial program that uses X11 contact your vendor for an updated version. If it begins with /opt/local, it is MacPorts if it begins with /sw, it is Fink. If step 3 outputs anything, it indicates that a system-wide change was made that is overriding yourĮnvironment. If step 2 outputs anything, it indicates that a configuration file in your home directory may be theĬulprit try creating a new user and repeating the steps with that user. If step 1 returns :0, localhost:0 or anything similar, you have a configuration file that is overriding
remote $ grep X11 /etc/ssh/sshd_config ~/.ssh/* local $ grep -r DISPLAY /opt/local/etc /sw/etc /etc 2>/dev/null local $ grep DISPLAY ~/.*rc ~/.login ~/.*profile ~/.MacOSX/ist 2>/dev/null Edit or create the file “~/.ssh/config” on the Mac and add these three lines:.Enable the first option: “Authenticate connections”.
Start XQuartz, go to Preferences with “Cmd-,” and go to the Security tab.Ssh -Y : “Warning: No xauth data using fake authentication data for X11 forwarding.” Ssh -X : “Warning: untrusted X11 forwarding setup failed: xauth key data not generated.” SSH will suddenly fail with one of the following error messages: Unfortunately, these two files are often overwritten during a macOS update,Īnd the specific SSH settings that XQuartz needs are then lost. The XQuartz installer should automatically point SSH to the correct location of xauth by editing ssh_config and sshd_configĭuring its post-install script. Have an administrator edit that system’s sshd_config file. If you are sshing to another system, be sure that remote server allows ssh forwarding. Tighter security, it is preferred over ‘ssh -Y’ see the SSH manual. You can forward X11 over an SSH connection by using either ‘ssh -X’ or ‘ssh -Y’.
