Resolution
Resolution Steps:
Step 1:
Logged-in to the SANnav server CLI and check the Internal SSH port under:
#<install_home>/conf - entry 'dcm.ssh.server.port'
bin]# ./show-sannav-configurations.sh
In case the SSH port #22 is held by the SANnav Server, then change the SSH for the SANnav application from port #22 to #6022 under:
#/etc/ssh/sshd_config
Change the ssh port to 6022 by uncommenting it:
Port 6022
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::
Add the port #6022 to the firewalld:
#firewall-cmd --permanent --add-port=6022/tcp
Restart the firewalld:
#systemctl restart firewalld
#<install_home>/conf - entry 'dcm.ssh.server.port'
bin]# ./show-sannav-configurations.sh
In case the SSH port #22 is held by the SANnav Server, then change the SSH for the SANnav application from port #22 to #6022 under:
#/etc/ssh/sshd_config
Change the ssh port to 6022 by uncommenting it:
Port 6022
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::
Add the port #6022 to the firewalld:
#firewall-cmd --permanent --add-port=6022/tcp
Restart the firewalld:
#systemctl restart firewalld
