Invalid magic cookie when connecting in mac

I am trying to access a remote ubuntu server through ssh -X from mac. I enabled X11 Forwarding in the sshd_config. After connecting the ubuntu, when I try to start wireshark, I get the below error

Invalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyError: Can't open display: localhost:10.0

thanks

Solution

  • Do an 'xhost +' on the host Mac (look up the man page for xhost if you want it more secure than allowing all X11 hosts to connect), then ssh -X.
