I have installed Xming successfully on a Windows XP system. It works OK to a FC6 system and an older UNIXware system. However when trying to connect to a FreeBSD 6.2 system with PuTTY ssh it doesn't work. PuTTY has Enable X11 forwarding checked. Here's what I get: $ $ xhost Xlib: connection to "localhost:10.0" refused by server Xlib: PuTTY X11 proxy: wrong authentication protocol attempted xhost: unable to open display "localhost:10.0" $ What can be wrong? I have ssh configured as follows: # grep X11 /etc/ssh/* /etc/ssh/ssh_config:ForwardX11 yes /etc/ssh/ssh_config:ForwardX11Trusted yes /etc/ssh/sshd_config:X11Forwarding yes /etc/ssh/sshd_config:X11DisplayOffset 10 /etc/ssh/sshd_config:X11UseLocalhost yes Here is the Xming log file: Welcome to the Xming X Server Vendor: Colin Harrison Release: 6.9.0.24 FreeType2: 2.3.0 Contact: http://sourceforge.net/forum/?group_id=156984 C:\Program Files\Xming\Xming.exe :0 -ac -clipboard -multiwindow XdmcpRegisterConnection: newAddress x.x.x.x winPrefsLoadPreferences: C:\Program Files\Xming\Xmingrc LoadPreferences: Done parsing the configuration file... winAdjustVideoModeShadowGDI - Using Windows display depth of 32 bits per pixel winAllocateFBShadowGDI - Creating DIB with width: 1600 height: 1200 depth: 32 winInitVisualsShadowGDI - Masks 00ff0000 0000ff00 000000ff BPRGB 8 d 24 bpp 32 glWinInitVisuals:1511: glWinInitVisuals init_visuals:1055: init_visuals null screen fn ReparentWindow null screen fn RestackWindow InitQueue - Calling pthread_mutex_init InitQueue - pthread_mutex_init returned InitQueue - Calling pthread_cond_init InitQueue - pthread_cond_init returned winInitMultiWindowWM - Hello winInitMultiWindowWM - Calling pthread_mutex_lock () winMultiWindowXMsgProc - Hello winMultiWindowXMsgProc - Calling pthread_mutex_lock () glWinScreenProbe:1390: glWinScreenProbe fixup_visuals:1303: fixup_visuals init_screen_visuals:1336: init_screen_visuals (--) 5 mouse buttons found (--) Setting autorepeat to delay=500, rate=31 (--) winConfigKeyboard - Layout: "00000409" (00000409) (--) Using preset keyboard for "English (USA)" (409), type "4" Could not init font path element C:\Program Files\Xming/fonts/misc/, removing from list!
