X11 Unsupported authorisation protocol

885068Nov 1 2017 — edited Nov 13 2017

Hello-

I'm unable to fix my X11 forwarding & I'm using Xming Server.

I have X11 forwarding enabled in my Putty settings as well as in the /etc/ssh/sshd_config. Could someone help me what I might be missing ?

[oracle@hostname ssh]$ xclock

Xlib: connection to "localhost:10.0" refused by server

Xlib: PuTTY X11 proxy: Unsupported authorisation protocol

Error: Can't open display: localhost:10.0

[oracle@hostname ssh]$ cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1               hostname.domainname hostname localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

[oracle@hostname ssh]$ sudo cat sshd_config |grep X11

X11Forwarding yes

#X11DisplayOffset 10

#X11UseLocalhost yes

#     X11Forwarding no

[oracle@hostname ssh]$ echo $PATH

/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/oracle/bin

[oracle@hostname ssh]$ echo $DISPLAY

localhost:10.0
