'''NOTICE: making anything visible outside your network can open security issues, so you are doing this at your own risk. Some apps are more secure than others, but there is nothing ultimately secure. Best is to use the [[VPN]] to login back home.
To access the HDA itself from outside the network using VPN, check out the [[Adito|OpenVPN ALS]] application, available to install through the HDA. Adito It enables you to access the HDA, and all applications and folders, using just your free username.yourhda.com webaddress.

* [[VNC]] access to your HDA if headless
** ''Terminal is available under Applications -> System Tools -> Terminal''
* [http://www.amahi.org/apps/ajaxterm Ajaxterm] SSH if headless and no VNC
* A monitor if you are not headless
To host your own web site you need the following:
What you need to do in a terminal (as root) is find the apps conf file then edit the conf file for the app:
{{Code| su -Code=su ls /etc/httpd/conf.d[enter password]:: '''NOTE:''' If you get a message like ''"ls : cannot access /etc/httpd/conf.d: No such file or directory"'', simply use the following to manually change directories: cd /etc/httpd/conf.d ls }}
Find your app .conf file. It will look like 10##-yourwebappname.conf
{{Code|Code= nano /etc/httpd/conf.d/10##-yourwebappname.conf :: '''yourwebappnameNOTE:'''Depending on the options you chose during installation, you may not have the "nano" text editor installed. If that is the case, you will receive an error message. Instead, substitute "vi" for "nano" to use a different text editor. [http://www.cs.conf}}colostate.edu/helpdocs/vi.html Here are the commands to use the "vi" editor.]
Your conf file should look something like this at the top of the page:
{{Text|<pre>
<VirtualHost *:80>
ServerName app
ServerAlias app.YourDomain.lan
}}</VirtualHost></pre>
Add this (immediately after the ServerName directive):
{{Text|<pre>
ServerAlias username.yourhda.com
}}</pre>
So it looks like this:
{{Text|<pre>
<VirtualHost *:80>
ServerName app
ServerAlias app.YourDomain.lan
ServerAlias username.yourhda.com
}}</VirtualHost></pre>
You can add more server aliases if you want to access the app under those names (for example: ServerAlias myphotos.DomainName.com). Once you are satisfied with the server aliases, you may save and quit nano by following these steps in Windows:
Restart the server using:
{{Code|* Fedora systemctl restart httpd.service * Ubuntu sudo service httpd apache2 reload}} And you are done, enjoy your website.... or are you? '''WARNING:'''Some apps will work right out of the box so to speak with these steps. Others however, (such as mediawiki) will require additional work before you can visit them on the internet. You will need to edit the apps config file to change the server address of that app. We will use mediawiki as an example. So suppose I have a domain name, which is pointed at my hda - and I set up a subdomain that for the mediawiki app. We'll call it mediawiki.myname.com. After installing media wiki, I need to go sudo vi /var/hda/web-apps/mediawiki/html/LocalSettings.php And scroll down to <pre>## The protocol and server name to use in fully-qualified URLs$wgServer <nowiki>=</nowiki> "http://mediawiki";</pre>then change to <pre>$wgServer <nowiki>=</nowiki> "http://mediawiki.myname. com";</pre> then enter these commands: sudo rm -r /etc/lock/apache2 sudo php /var/hda/web-apps/mediawiki/html/maintenance/Update.php sudo service apache2 restart Now you should be able to view http://mediawiki.myname.com from inside your network and on the internet as well.
= Hosting Multiple Webapps =
''If you wish to have access to multiple webapps, described below is one way to accomplish this('''NOTE:''' ''Requires a dnynamic DNS provider in addition to Amahi username.yourhda.com''):
# obtain a domain name (i.e., via godaddy.com) --for example yourdomain.com
# don't forget to restart the server each time you edit a .conf file.
:#:For example, you could create the subdomain/CNAME: address.yourdomain.com for the AddressBook webapp---point that subdomain to: username.yourhda.com---in the AddressBook .conf file add: ServerAlias address.yourdomain.com---restart the server---you are done, enjoy using multiple webapps! Even if you have a dynamic IP address from your ISP, this can still be done - rather inexpensively. Some [http://en.wikipedia.org/wiki/Dynamic_DNS dynamic DNS] services, like DynDNS, allow for you to create a domain and use something called a [http://en.wikipedia.org/wiki/Wildcard_DNS_record wildcard DNS record]. This acts much like the subdomain created above, but you can literally use anything you want so long as the server is set to answer to the request. Below, we'll outline the basic steps needed to accomplish this. Some routers (Netgear, Linksys, etc.) allow you to set up credentials for your dynamic DNS service account so that it'll update the dynamic DNS service for you. If you don't have that ability, you may have to run a client-side application on a computer inside your network which will send out regular updates to do the same thing. Figure out if you will be updating the dynamic DNS service via the router or a client-side app. Once you've confirmed you can utilize this technology, in one form or another, proceed with the rest of these basic steps. # Obtain a ''paid'' DynDNS account.## At the time of this writing, DynDNS is calling it their ''Pro'' account.## Basic accounts will not allow you to use wildcards.# In your Amahi's web-GUI, navigate to your [[Media:Amahi-webapps.PNG|Webapps]] section via '''Apps > Webapps''' (Ubuntu). The Amahi [https://www.amahi.org/apps/web-apps Web App] provides this functionality in Amahi 7.# In our case, we'll be allowing our Dokuwiki to answer to our wildcard DNS record so expand it by clicking on it.## This will show several options to edit but we're only going to add an '''alias'''.### Click on '''New Alias'''.### Enter your wildcard like what we have in our [[Media:Amahi-webapps-wiki-alias.PNG|example]].#### If your DynDNS account is '''tommy.homedns.org''', you'll enter something like '''wiki.tommy.homedns.org'''. Again, DynDNS allows for wildcards so you can make up stuff all day long! You should be able to test this by now however, it may prove difficult to accurately test it from inside your own network. In that case, bug your friend down the street to see if they can get to it or do it yourself at a later date. '''For the curious:'''So, what did this do? Well, what it did was add a [http://httpd.apache.org/docs/current/mod/core.html#serveralias ServerAlias] directive to the Apache configuration. (In MS-IIS, it's called a host header or a binding.) You can have as many ServerAlias' as you'd like. So, if you wanted to take a look under the hood, you would open a terminal window on your server (or SSH to it) and do a directory listing of '''/etc/httpd/conf.d/'''.<pre>user@ubuntu-amahi1:~$ ls -l /etc/httpd/conf.d/total 28-rw-r--r-- 1 root root 21 Oct 10 18:46 00-init.conf-rw-r--r-- 1 root root 2231 Oct 10 18:46 01-platform.conf-rw-r--r-- 1 root root 516 Oct 10 18:46 03-calendar.conf-rw-rw-r-- 1 nobody nogroup 518 Feb 1 09:20 1000-dokuwiki.conf-rw-rw-r-- 1 www-data users 492 Oct 10 21:14 1001-phpsysinfo.conf-rw-rw-r-- 1 www-data users 489 Oct 10 21:18 1002-subsonic.confuser@ubuntu-amahi1:~$</pre>In our case, when we installed the Dokuwiki app, it created '''1000-dokuwiki.conf'''. Open that and you'll see the ServerAlias that was added. user@ubuntu-amahi1:~$ nano /etc/httpd/conf.d/1000-dokuwiki.conf<pre><VirtualHost *:80> ServerName dokuwiki ServerAlias dokuwiki.home.local ServerAlias wiki.tommy.homedns.org DocumentRoot /var/hda/web-apps/dokuwiki/html <Directory "/var/hda/web-apps/dokuwiki/html"> Options Indexes FollowSymLinks +ExecCGIAddHandler fcgid-script .fcgAllowOverride FileInfo Limit Options IndexesOrder allow,denyAllow from all </Directory> ErrorLog /var/hda/web-apps/dokuwiki/logs/error_log CustomLog /var/hda/web-apps/dokuwiki/logs/access_log combined env=!dontlog </VirtualHost></pre> You can see that adding that ServerAlias added the line: '''ServerAlias wiki.tommy.homedns.org''' = Hosting Webapps (Change Port)=This is an alternate method for hosting single or multiple web apps using the builtin Amahi dynamic DNS (''username.yourhda.com''). This will likely work with other dynamic DNS providers. You can change the port that most web apps operate, specifically port 80. You can use any port not already in use by the OS or your HDA. To verify what ports are already in use, do (as ''root'' user): nmap -sT -O localhost Once you have chosen the port to use, follow the steps below (using [https://www.amahi.org/apps/adminer Adminer] as an example and port 8081): * Edit ''/etc/httpd/conf.d/####-adminer.conf'' and add the following line. Also change 80 to 8081 in the VirtualHost line: Listen 8081 <VirtualHost *:8081>* Update the ServerAlias: ServerAlias adminer.amahi.net:8081* Add right below ServerAlias to use the Amahi dynamic DNS: ServerAlias username.yourhda.com:8081* Restart web server: systemctl restart httpd Forward port 8081 on the router of course to access from outside the network. Anytime you access the app on your network internally, navigate to <nowiki>http://adminer.amahi.net:8081</nowiki>. :'''NOTE:''' ''amahi.net'' part of the URL may be different depending on the domain you use for your HDA. To change the app back to using port 80, remove the ''Listen'' line and change the port to ''80'' in ''/etc/httpd/conf.d/####-adminer.conf''. I would not recommend you try this with apps that do not use port 80. For example, an application that uses the web server proxy will most certianly not work with this method.
= Hosting a Website =
''Prerequisites'': The first order of business is to make sure that your domain name is pointing to your server's IP address. Each website is different, but [http://www.webhostingsearch.com/review/godaddy GoDaddy ] goes like this:
:* Go to your GoDaddy's ''My Account'' page. Under Dashboard, click yourdomain.com
:** Point your cursor at the Nameserver icon, click ''Set Nameservers''
We will create the website by creating a webapp. This is a lot easier than it sounds, so don't give up just yet!
# Got your HDA page (<nowiki>http://hda </nowiki> or <nowiki>http://hda.yourhda.com</nowiki>), click ''Setup'' and go to ''Settings''.
## Make sure your ''Advanced Settings'' option is checked (if not, check and click OK past the warning)
# Go to ''Apps'' and then ''Webapps''(Amahi 6). The Amahi [https://www.amahi.org/apps/web-apps Web App] application provides this functionality in Amahi 7.
# At the very bottom, click ''New Web App'' and type in a name like Website
:This is where your webpage will reside in, you can name this anything you'd like. This is not the title of your website or webpage. Website will be used as the name for this guide
= More Secure Access =
To enable https access to your apps, you can follow the techniques in [[Secure App Access]] page. '''NOTE:''' Recommend exercising extreme caution with this tutorial as it has been known to cause problems.
= FAQ =
this directory belongs to apache. you will have to change the
ownership to your user (recommended) or otherwise add things as root.
* Q: How do I change the ownership?
You can do this by going to the command screen:
{password}
chown {user} /var/hda/web-apps/
=Troubleshooting =
* Q: When I go to myusername.yourhda.com I get my router's homepage instead of my hda. How do I fix that?
If you see your router's page, that means the forwarding did not take place from the external port to the internal port in your HDA
* Q: I do not see the app I want when accessing myusername.yourhda.com
This may be because the corresponding virtualhost does not have the name you expect on it, or because another virtualhost already has it and happens to take over
