problems with web-apps proxy

[trebor]

I have just installed Web-Apps Proxy, but am having problems.

For the sake of this question, lets assume the following (john being a made-up name to represent my DNS alias) is in my apps-proxy.conf file:

ServerName apps-proxy
ServerAlias apps-proxy.john.com

When I go to http://apps-proxy when on a computer in my home network I get the login page, I log in, and I get the the Amahi Home Server > Web-Apps Proxy page with the list of my installed apps. However, when I click on one of my apps I am directed to http://apps-proxy/fcms (when I click on the family connections app tab) but get, "Not Found The requested URL /fcms/ was not found on this server."

When I go to http://apps-proxy.john.com I get the same error---I am directed to http://apps-proxy.john.com/fcms with the same "Not Found" error.

I can access the family connections page from my home server by typing: http://fcms/ or http://fcms.john.com

My ultimate goal is to be able to access apps-proxy from the internet from work, but think it best to get it working from inside my home network first...

Any tips would be much appreciated.

Do all your apps do the same, when started using http://apps-proxy ?

Some apps might not work well with apps-proxy yet. We tried many, and fixed some, but we didn't try all of them.
I'll check family connections now.

You can check that the config file of apps-proxy is correct: look in /etc/httpd/conf.d, there's a file named ####-apps-proxy.conf

That file should start with:

Code: Select all

ServerName apps-proxy ServerAlias apps-proxy.john.com ServerAlias trebor.yourhda.com

Following that, you should have 2 lines for each of your web-app:

Code: Select all

RewriteRule ^/fcms$ http://trebor.yourhda.com/fcms/ [L] RewriteRule ^/fcms/(.*) http://fcms/$1 [P]

Note that your browser needs to accept cookies for apps-proxy to work.
When you click a link in the apps proxy page, it sets a cookie with the hostname of the application you clicked (for example fcms), and apache will use that cookie to transform any incoming requests that look like
http://apps-proxy/ajaxterm/something or http://apps-proxy/something into a request to http://ajaxterm/something.

(The hostname you use to access apps-proxy doesn't matter. Both apps-proxy and apps-proxy.john.com should do the same when you're on your local network, and trebor.yourhda.com should do the same when accessing it via the internet.)

I made sure that my .conf file for apps-proxy included:
ServerName apps-proxy
ServerAlias apps-proxy.john.com
ServerAlias trebor.yourhda.com

The code for my various apps was not listed in the conf file so below the ServerName and ServerAlias section I added:


RewriteRule ^/fcms$ http://trebor.yourhda.com/fcms/ [L]
RewriteRule ^/fcms/(.*) http://fcms/$1 [P]

I still get "Not Found"

For some reason it does not appear that the incoming requests are being translated properly---when I click on fcms the address that is returned is: http://apps-proxy.john.com/fcms/

Also, this error occurs for all of my listed apps which include:
Amahi Dashboard
addbook
arcadem
fcms
gallery2
joomla
transmission
webcalendar
webvnc

cookies option is turned on and translation does occur---i.e., if I type fcms or hda I get the correct access to apps I would expect.

Paste the result of the following in a new post
(Please include the executed commands too, not just their result.)

(as root):

Code: Select all

cat /etc/httpd/conf.d/*apps-proxy.conf rpm -q amahi-webapps-proxy cat /etc/cron.d/amahi-apps-proxy grep apps-proxy /var/log/cron | tail /var/hda/web-apps/apps-proxy/html/refresh_httpd_conf.php /usr/bin/mysql -u root -phda -e 'SELECT name FROM webapps WHERE name != "apps-proxy" ORDER BY name ASC' hda_production | grep -v '^name$' ls -1 /etc/httpd/conf.d/*apps-proxy.conf cat /etc/httpd/conf.d/*apps-proxy.conf

[trebor]

That did the trick. Here is what happened:

[root@localhost robert]# cat /etc/httpd/conf.d/*apps-proxy.conf
<VirtualHost *:80>

ServerName apps-proxy
ServerAlias apps-proxy.baldwin.com
ServerAlias trebor.yourhda.com
ServerAlias hdapps.thebaldwinclan.com



RewriteRule ^/fcms$ http://trebor.yourhda.com/fcms/ [L]
RewriteRule ^/fcms/(.*) http://fcms/$1 [P]

Thanks!

Not sure how you can have a cron file that should be executed every minute, but isn't..?

If can help me debug further:

Code: Select all

service crond status tail /var/log/cron service crond reload sleep 70 grep apps-proxy /var/log/cron | tail

Wow... no crond! Since July 9th...
Any idea why?

Code: Select all

rpm -q cronie

If it's not installed, you should re-install it.

Code: Select all

yum -y install cronie

[trebor]

No, it was not not installed and no, I have no idea why it wasn't. Would this have been an Amahi auto update or a Fedora update? What would you suggest I check to determine why it wasn't?
