Failed to connect

Failed to Connect

Firefox can't establish a connection to the server at localhost:7080.

Though the site seems valid, the browser was unable to establish a connection.

    * Could the site be temporarily unavailable? Try again later.
    * Are you unable to browse other sites? Check the computer's network connection.
    * Is your computer or network protected by a firewall or proxy? Incorrect settings can interfere with Web browsing.

Sorry now I discovered the webpage.....http://www.schooltool.org/documentation/setting-up-a-development-server/your-development-environment

But there were some problems in the terminal........It got stuck for a long time on:

Reading configuration from /home/daniel/schooltool.stapp2008spring/instance/schooltool.conf
Starting server in PID 9180.
2008-05-21 06:34:59,428 Cannot use kill_thread_limit as ctypes/killthread is not available
serving on http://127.0.0.1:7080

Is it working now or are you still unable to connect?

Yes.

Looking above (cannot use kill_thread_limit as ctypes.....), can I continue somewhere in the terminal maybe I'll be lucky?

The message above doesn't indicate that the server is "stuck," but that it is running. Did you try using 127.0.0.1 instead of "localhost?" Also, are you using a svn checkout rather than the release debs?

What command do I need to write in the terminal to try 127 ....etc ?

Please explain svn checkout and release debs.

In firefox, try http://127.0.0.1:7080

Also, did you follow these instructions? http://www.schooltool.org/installing-schooltool Those are the released packages.

Schooltool was working perfectly before I installed XAMPP on the same machine and tried connecting with http://localhost for Xampp. Xampp worked but thereafter Schooltool refused to work, I even uninstalled xampp yet schooltool will not work. Please help me out.

Can you post the contents of your /etc/hosts file?
Try connecting to http://localhost:7080/ to http://127.0.0.1:7080/
Try "ping 127.0.0.1" "ping localhost"

127.0.0.1 localhost
192.168.0.1 ubunSvr710

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Above is the content of /etc/hosts file and ping 127.0.0.1 replied correctly

Hi Ignas,

I can ping 127.0.0.1 and it replies. Below is the content of /etc/hosts file

127.0.0.1 localhost
192.168.0.1 ubunSvr710

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

This problem started after i installed xampp, and u know xampp also use localhost for testing page, so i uninstalled xampp, yet the prolem persist. When I tried to restart schooltool, it says :

 * Restarting SchoolTool-2008... Changing user to schooltool:schooltool (109:120)
No PID file exists in /var/run/schooltool/schooltool-2008.pid
Could not stop daemon; aborting

Please help.

Regards!

David

Dear all,
I just interested Schooltool. I installed schooltool - 2008, it run ok. When the Schooltool -2009 open, I updated Schooltool- 2008 to Schooltool-2009. And then I configure Schooltool view in Vietnamese language. I saw it didnt view very well. I have removed Schooltool and reInstalled it successfully. But when I run http://localhost:7080 it didnt run and view "Failed to Connect, Firefox can't establish a connection to the server at localhost:7080." I tried to run http://127.0.0.1 it view "It works!".

I try many ways but http://localhost:7080 cant work.

Can you help me fix this problems?

Thanks and the best regards,

There are problems starting schooltool after installation, so please try starting it
    /etc/init.d/schooltool-2009 start
and then http://127.0.0.1:7080 should work

I have same problem.

Tried: starting it
    /etc/init.d/schooltool-2009 start

no go

Output:

:~$ /etc/init.d/schooltool-2009 start

Yes, permission will be denied like that. You need root access to issue that command. So issue it like this;

sudo  /etc/init.d/schooltool-2009 start

it will work this time.

please get be back the answer at <email address hidden>

I'm not sure why you're REstarting. This error is telling you it isn't already running. Can you just start SchoolTool?

Yes, schooltool-2009 script is a bit dumb, you can't restart a service that is not running.

$ sudo /etc/init.d/schooltool-2009 start
should work.
