I just installed Ubuntu. How do I set it up to allow me to ws into it?

Right now I get "ws:// connect to host x.x.x.x port 8888 : no response". for example ws://172.23.45.100:8888 don't give any response and cannot open

output of sudo iptables -L

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

I can ping the ip from another windows app , but when telnet it fails to connect telnet 172.123.45.100 8888

also this is the output sudo netstat -tnlp|grep 8888

tcp6       0      0 :::8888                 :::*                    LISTEN

yes it run and listening – AMH Jan 05 '17 at 10:33
all I need is to open this port for world – AMH Jan 05 '17 at 10:33
So you didn't just install Ubuntu, you have installed other software on it. Did you install ufw? Also, edit your post to include the output of sudo netstat -tnlp | grep 8888 and ip a – muru Jan 05 '17 at 10:36
the output of the command "Can't open 8888 no such file or directory" also I didn't install ufw – AMH Jan 05 '17 at 10:42
sorry output is tcp6 0 0:::8888 :::* LISTEN @muru – AMH Jan 05 '17 at 10:44
is it important to install ufw – AMH Jan 05 '17 at 10:49
OK, please [edit] your post to include the output of sudo iptables -L – muru Jan 05 '17 at 10:50
@muru kindly find updated question – AMH Jan 05 '17 at 10:54
So your service is listening on the correct port, you don't have any firewal rules blocking the port, so the last thing is: is the IP correct? Is the computer otherwise accessible from the other computers? – muru Jan 05 '17 at 10:55
I can ping the ip from another windows app – AMH Jan 05 '17 at 11:00
but not on the port from windows telnet doesn't response @muru – AMH Jan 05 '17 at 11:07
