We need to add parameter -p 13000 to click configuration

change line in /tce/etc/wanos/wanos

sudo /usr/local/bin/click -j6 -w wanos.click >> /wanos/wanos.log 2>> /wanos/wanos.log &

to

sudo /usr/local/bin/click -j6 -p 13000 -w wanos.click >> /wanos/wanos.log 2>> /wanos/wanos.log &

now you are able to telnet to port 13000

root@wanos:/home/tc# telnet localhost 13000
