Hello to everone,

I've got some problems to connect to jobe (Version: 1.7.0, 27 November 2022) from moodle 4.01 with the coderunnerplugin (Version: 5.1.1 9 November 2022)

the jobeserver is simply called "jobe" and is reachable in the network:

root@moodle:/var/www/html/jobe# ping jobe
PING jobe (192.168.2.188) 56(84) bytes of data.
64 bytes from jobe (192.168.2.188): icmp_seq=1 ttl=64 time=0.285 ms
64 bytes from jobe (192.168.2.188): icmp_seq=2 ttl=64 time=0.217 ms

the moodle server is also simply called "moodle" in this testsetup.

root@moodle:/var/www/html/jobe# ping moodle
PING moodle (192.168.2.37) 56(84) bytes of data.
64 bytes from moodle (192.168.2.37): icmp_seq=1 ttl=64 time=0.082 ms
64 bytes from moodle (192.168.2.37): icmp_seq=2 ttl=64 time=0.084 ms


1) I can connect with the testscript:

root@moodle:/var/www/html/jobe# python3 testsubmit.py --host=jobe --port=80

3) but I do get an "Jobe server request failed. URL is blocked." if I try to run the python 3 sqr example within moodle.

In the moodle-coderunner-plugin section I tried already:

jobe

jobe:80

http://jobe:80

and even the direct IP address ... nothing worked

but funnily if I try the testserver jobe2.cosc.canterbury.ac.nz everything works perfectly.

I would really appreciate any advice

thanx a lot

Lars

Re: problem connecting to jobe

Found the problem :)

In the HTTP security options on the moodle-server (site administration -> General -> security -> http security) the "private" network had been blocked

therefor for everyone who wants to test this in their home network

hint: change cURL blocked hosts list to

10.0.0.0/8
172.16.0.0/12
0.0.0.0
169.254.169.254
