JATOS server account

DDD

Hi,

I want to create an online experiment using Opensesame. The tutorial said that the JATOS server account was needed for the online experiment. As far as I know, my university (Zhejiang University, China) did not have JATOS server account, or I can`t find relevant information about it. And how can I get an account?

Best,

Donglin

Hi Elisa,

Thank you for your reply. I have followed the steps on this website. I used Alibaba Cloud (almost followed the tutorial in the AWS section). I have started JATOS, but I can`t open the JATOS panel on the server. I don`t know how to fix it.

Sorry for I`m new to computer science:( 

(172.xx.xxx.xx is my private IP, and 47.xxx.xxx.xxx is my public IP)

Best,

Hi Donglin,

I've never tried JATOS on Alibaba, but it should work there like on any other server.

Let me ask you a couple of questions to get closer to the problem:

• Which version of JATOS do you use?
• Do you use any proxy in front of JATOS (e.g. Apache or Nginx)?
• Did you change IP and port in conf/production.conf or loader.sh and if yes to which values?

Best,

Kristian

Hi Kristian,

I found my problem and solved it!?

Now, I can run my experiment online.

Thanks for your help.

Hello,

I'm having the same problem with AWS. I have version 3.5.2 of JATOS, no proxy, and the IP is set to my private IP using port 80. Not sure what Donglin did to fix theirs. Any suggestions on what the problem might be?

Hi stpier43,

It would be better you open a new thread next time. Although yours is the same general topic the actual problem is most likely a different one.

Anyway, so you are using AWS, JATOS v3.5.2 and no proxy. Two things I can think of

1) You say, your JATOS uses no proxy (which is not necessary if you don't want to use encryption) and you configured the conf/production.conf to use port 80. To bind any program including JATOS to port 80 one has to start it with root user. Did you start JATOS as root?

2) One has to allow inbound HTTP traffic: https://aws.amazon.com/premiumsupport/knowledge-center/connect-http-https-ec2/

Hope this helps,

Kristian
