Installation problems (on behalf of Jan Wildenhain)

[sloynton]

I have a technical issue. The server ist running, the weblogin works
fine on the server. But I can not use the client to login from another
machine, or start the weblogin from other machines.

I opened port the ports 8000, postgres, and the z-zero ports on server
and client. Still it can not login.
I tried the the /etc/hosts thing as well - still does not work.


Any help appreciated.

Cheers

Jan

Hi Jan

Could you please confirm you configured different host in your /home/omero/omero_dist/lib/python/omero/plugins/server.py:

Code: Select all

    def web(self, args):
        (...)
        django = ["python","manage.py","runserver","0.0.0.0:8000","--noreload"]+list(args)

and in /home/omero/omero_dist/etc/grid/templates.xml by adding after --noreload:

Code: Select all

    <server-template id="WebTemplate">
      <parameter name="act" default="on-demand"/>
      <server id="Web" exe="python" activation="${act}" pwd="${OMEROPY_HOME}omeroweb">
        <option>manage.py</option>
        <option>runserver</option>
        <option>--noreload</option>
        <option>10.0.0.1:8000</option><!-- your ip & port here -->
        <env>${PYTHONPATH}</env>
        <adapter name="WebAdapter" register-process="true" endpoints="tcp" server-lifetime="false"/>
      </server>
    </server-template>

Please be aware that OMERO platform includes a development server (a lightweight Web server written purely in Python), which is ideal for demonstrating/testing how powerful OMERO platform is. Unfortunately, this server is only designed to run in a local environment and could not deal with the pressures of a production mode of the application used by many people concurrently. For that, you need to deploy OMERO.web to a production-grade web server, such as Apache.

You will need mod_python http://www.modpython.org/ module for Apache http://httpd.apache.org/

For more details how to run the OMERO.web in the production mode please follow the instruction on:
http://www.openmicroscopy.org.uk/site/s ... nstall-web Configuration Guide for mod_python (production) section.

Do you have TCP/4063 open?

[blah]

port 4063 is open on the server and the client side.

[cxallan]

We'll need one of the log files from the client then please.

Mac OS X:

/Users/<username>/omero/log

Windows:

C:\Documents and Settings\<username>\omero\log

[blah]

After I modified server.py and the xml file I can execute this line on the localhost but not from other machines.

http://biogrid.bio.ed.ac.uk:8000/webclient/login/

[blah]

On my windows client no log file is created. I let you know if I can find one on the mac.

Btw. My posgres sever has utf encoding instead of omero | omero | SQL_ASCII encoding, could this turn into an issue?

[blah]

Apologies,

found it. The server can't connect. I shutdown the firewall and everything works. Here is my iptables file. Can you tell me which ports are missing?

*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

The problem looks to be the order of your rules not the ports. iptables uses a first match wins algorithm. So, the four rules you have after your jumps to REJECT will never be matched.

[blah]

Thanks cxallan,

have done firewall modifications for a long time now and have never been aware of it.

Best
