Are you trying to hit the server using curl from outside the server? If so, what happens? If the çurl requests don't work, it's a port mapping or firewall issue.
If curl works but the browser doesn't, you have to be careful with the same-origin policy. The same-origin policy says that the requests have to go to the same protocol, server domain and port of the page. You can get around that using CORS, which is basically a set of extra headers added by the server. You also need to be careful with the content type and CORS. https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS Gustavo On Thu, Oct 6, 2016 at 3:14 AM, amal kumar <[email protected]> wrote: > Hi Tapo, > > I have added the above configuration to the iptables, but still no luck. > > sudo iptables -L -n: > [image: Inline image 1] > > Also, > $ sudo iptables -S > -P INPUT ACCEPT > -P FORWARD ACCEPT > -P OUTPUT ACCEPT > -A INPUT -p tcp -m tcp --dport 7070 -j ACCEPT > -A INPUT -p tcp -m tcp --dport 8000 -j ACCEPT > > > $ sudo ip6tables -S > -P INPUT ACCEPT > -P FORWARD ACCEPT > -P OUTPUT ACCEPT > > > $ netstat -nlp > Proto Recv-Q Send-Q Local Address Foreign Address State > PID/Program name > tcp 0 0 0.0.0.0:22 0.0.0.0:* > LISTEN - > tcp 0 0 127.0.0.1:5432 0.0.0.0:* > LISTEN - > tcp6 0 0 :::36301 :::* LISTEN > 31215/java > tcp6 0 0 172.31.12.251:52787 :::* > LISTEN 31215/java > tcp6 0 0 :::22 :::* LISTEN > - > tcp6 0 0 :::7070 :::* LISTEN > 30707/java > tcp6 0 0 :::8000 :::* LISTEN > 31215/java > tcp6 0 0 :::41057 :::* LISTEN > 31215/java > tcp6 0 0 :::4040 :::* LISTEN > 31215/java > udp 0 0 0.0.0.0:68 0.0.0.0:* > - > udp 0 0 0.0.0.0:34499 0.0.0.0:* > - > udp6 0 0 :::42478 :::* > - > Active UNIX domain sockets (only servers) > Proto RefCnt Flags Type State I-Node PID/Program > name Path > unix 2 [ ACC ] SEQPACKET LISTENING 7434 - > /run/udev/control > unix 2 [ ACC ] STREAM LISTENING 8718 - > /var/run/dbus/system_bus_socket > unix 2 [ ACC ] STREAM LISTENING 8978 - > /var/run/acpid.socket > unix 2 [ ACC ] STREAM LISTENING 457 - > @/com/ubuntu/upstart > unix 2 [ ACC ] STREAM LISTENING 8044 - > /var/run/postgresql/.s.PGSQL.5432 > > > > Thanks, > Amal Kumar > > On Wed, Oct 5, 2016 at 3:28 PM, Sunny <[email protected]> wrote: > >> Hello Amal, >> >> Try running following commands on your SSH terminal (on AWS linux), >> sudo iptables -A INPUT -p tcp -m tcp --dport 7070 -j ACCEPT >> sudo iptables -A INPUT -p tcp -m tcp --dport 8000 -j ACCEPT >> >> This should allow TCP input traffic to both the ports. >> In case it doesn't work, send output of the following command, >> sudo iptables -L -n >> >> -- Tapo >> >> On Wed, 5 Oct 2016 at 09:40 amal kumar <[email protected]> wrote: >> >>> Hi, >>> >>> As my understanding, i have updated the ec2 security group as below. >>> Still not able to connect from web browser outside SSH >>> >>> Inbound: >>> [image: Inline image 1] >>> >>> Outbound: >>> [image: Inline image 2] >>> >>> >>> iptables Status: >>> >>> $ sudo iptables -S >>> -P INPUT ACCEPT >>> -P FORWARD ACCEPT >>> -P OUTPUT ACCEPT >>> >>> ip6tables Status: >>> >>> $ sudo ip6tables -S >>> -P INPUT ACCEPT >>> -P FORWARD ACCEPT >>> -P OUTPUT ACCEPT >>> >>> >>> >>> $ netstat -nlp >>> (Not all processes could be identified, non-owned process info >>> will not be shown, you would have to be root to see it all.) >>> Active Internet connections (only servers) >>> Proto Recv-Q Send-Q Local Address Foreign Address >>> State PID/Program name >>> tcp 0 0 0.0.0.0:22 0.0.0.0:* >>> LISTEN - >>> tcp 0 0 127.0.0.1:5432 0.0.0.0:* >>> LISTEN - >>> tcp6 0 0 :::22 :::* >>> LISTEN - >>> tcp6 0 0 :::56568 :::* >>> LISTEN 1848/java >>> tcp6 0 0 :::7070 :::* >>> LISTEN 1333/java >>> tcp6 0 0 :::8000 :::* >>> LISTEN 1848/java >>> tcp6 0 0 :::40356 :::* >>> LISTEN 1848/java >>> tcp6 0 0 172.31.12.251:48166 :::* >>> LISTEN 1848/java >>> tcp6 0 0 :::4040 :::* >>> LISTEN 1848/java >>> udp 0 0 0.0.0.0:68 0.0.0.0:* >>> - >>> udp 0 0 0.0.0.0:55452 0.0.0.0:* >>> - >>> udp6 0 0 :::22478 :::* >>> - >>> Active UNIX domain sockets (only servers) >>> Proto RefCnt Flags Type State I-Node PID/Program >>> name Path >>> unix 2 [ ACC ] STREAM LISTENING 8980 - >>> /var/run/postgresql/.s.PGSQL.5432 >>> unix 2 [ ACC ] STREAM LISTENING 7313 - >>> @/com/ubuntu/upstart >>> unix 2 [ ACC ] SEQPACKET LISTENING 7575 - >>> /run/udev/control >>> unix 2 [ ACC ] STREAM LISTENING 8941 - >>> /var/run/acpid.socket >>> unix 2 [ ACC ] STREAM LISTENING 7934 - >>> /var/run/dbus/system_bus_socket >>> >>> >>> >>> Can you please suggest, which network setting is missing here?
