Re: [Virtuoso-users] What is preventing external connections to TCP port 1111 to connect to Virtuoso running within a Docker container?

2019-10-03 Thread Hugh Williams 
Hi Allan,

If you can access the HTTP port 8890 from external machine then there is no 
reason why you would not be able to access the SQL TCP port  (given you can 
access it from the host machine ie localhost:1112) other then there is a 
problem with the network firewall on the host machine (or wherever this is 
enforced) that is prevent access to TCP port 1112 from external machines. Thus 
you should check your fire walling ...

BTW, I presume this is you own docker image that was create, rather then using 
the OpenLink Virtuoso 7 open source docker image at:

https://hub.docker.com/r/openlink/virtuoso-opensource-7/

[Virtuoso-users] What is preventing external connections to TCP port 1111 to connect to Virtuoso running within a Docker container?

2019-10-03 Thread Allan Kamau 
What is preventing external connections to TCP port  to connect to
Virtuoso running within a Docker container?


Short story.
I am unable to connect to port 1112 (which is mapped to  in the docker
container construction command) from the external network interface.
I am able to connect to port  from inside the docker container on both
localhost and external network interfaces.
>From the computer on which the docker container is running I am able to
connect to port 1112 (which is mapped to  in the docker container
construction command) if I connect via localhost.
$ time nc -zv localhost 1112;
Ncat: Version 7.50 ( https://nmap.org/ncat )
Ncat: Connected to ::1:1112.


Long story.
The docker container start script has instructions to map host TCP port
1112 to TCP docker container port .
I have installed Virtuoso 7.2.6-dev on a CentOS 7 in a docker image.
In the docker container generation command that spawns a new docker
container from the above image, I have exposed TCP port 8891 (of the host)
to connect to TCP 8890 (of the container), and TCP port 1112 (of the host)
to connect forward to TCP port  (of the container).

>From the docker container hosting computer, I can successfully connect to
port 8891 but I cannot connect to port 1112. See below.

$ time nc -zv ${HOSTNAME} 8891;
Ncat: Version 7.50 ( https://nmap.org/ncat )
Ncat: Connected to 10.74.218.8:8891.
Ncat: 0 bytes sent, 0 bytes received in 0.02 seconds.

$ time nc -zv ${HOSTNAME} 1112;
Ncat: Version 7.50 ( https://nmap.org/ncat )
Ncat: No route to host.

interface, see below.

The command below shows the configuration for the "ServerPort" variable in
the virtuoso.ini of the Virtuoso instance I have running.
grep -R "ServerPort" virtuoso.ini;
returns the output below.

ServerPort  = 
;SSLServerPort  = 2111
ServerPort  = 8890
