The X11 forwarding request was rejected! solaris 10

When i was trying to connect to one of Solaris 10 server using xmanager then it was unable to connect displaying error message "The X11 forwarding request was rejected!"

Error screen:




cause:

In sshd configuration file X11Forwarding option was disabled

Solution:

step1

cat /etc/ssh/sshd_config | grep X11
# X11 tunneling options
X11Forwarding no
X11DisplayOffset 10

bash-3.00# cat /etc/ssh/sshd_config | grep ListenAddress
# Multiple ListenAddress entries are allowed.
#ListenAddress 0.0.0.0
ListenAddress :: #This if for IPV4 and IPv6

change above values as below in /etc/ssh/sshd_config file :

X11Forwarding yes

#ListenAddress :: #(comment this line)
ListenAddress 0.0.0.0 #(uncomment this entry) - if not exist in file add it.

Step 2

add -4 option for ssh command:

original entry


        # SMF arguments (start and restart [really "refresh"])
'start')
        /usr/lib/ssh/sshd 
        ;;


update entry

        # SMF arguments (start and restart [really "refresh"])
'start')
        /usr/lib/ssh/sshd -4
        ;;

Step 3

restart ssh daemon an verify its running:

bash-3.00# svcadm restart ssh

bash-3.00# svcs ssh
STATE          STIME    FMRI
online         10:08:39 svc:/network/ssh:default
bash-3.00#

After this you should be able to login to server via xmanager using ssh .
