Description Piero Malcovati 2016-05-13 09:01:37 UTC 
After installing XQuartz 2.7.9 on MacOSX 10.11.4, if I start XQuartz, type xhost + and then rlogin to a remote server, setenv DISPLAY to <hostname_of_my_mac>:0.0 and run for example xterm, I get the error:
xterm: Xt error: Can't open display: <hostname_of_my_mac>:0.0

Before updating to 2.7.9 (with 2.7.8) the same commands were working fine.

In XQuartz preferences both Authenticate Connections and Allow Connections from Network Clients are enabled.

I also tried to start XQuartz, type xhost +, setenv DISPLAY localhost:0.0 on my Mac, when launching xterm I get the same error, whereas if I setenv DISPLAY :0.0 it works fine.

I tried to delete the .Xauthority file but nothing changed.

With ssh -X everything works fine.

Help please.

Thank you.

I think I remember seeing that xorg-server was disabling TCP by default.  We can probably re-enable it if that's the case.

Can you please let me know when a version with this bug fixed will be available (also beta).
Thank you.
Comment 3 Piero Malcovati 2016-05-16 15:25:19 UTC 
I was able to fix the problem by adding after line 107 of /opt/X11/bin/startx
    defaultserverargs="$defaultserverargs -nolisten tcp"
the following two lines:
else
    defaultserverargs="$defaultserverargs -listen tcp"
Now everything works!!

This should be addressed in XQuartz 2.7.10 beta2 or later (not released yet).
