ELOG SSL Configuration

The Electronic Logbook (ELOG) package developed by Stefan Ritt can be installed on Windows or Linux systems and provides blogging capability.

The following steps can be used to configure ELOG to use Secure Sockets Layer (SSL) for encrypted connectivity to the server. I.e. you can use Hypertext Transfer Protocol over Secure Socket Layer or HTTPS.

  1. Edit the elogd.cfg file with a text editor, such as Notepad, if you installed ELOG on a Windows system. On a Windows system, the file is installed by default in C:\Program Files\ELOG If it wasn't installed in the default location and you don't know where it was installed, you can use the instructions in ELOG Port Configuration to determine its location.
  2. Add the following line to the [global] section of the file:

    SSL = 1
  3. Restart the ELOG webserver. Instructions for restarting the elogd service on a Windows system through a Graphical User Interface (GUI) can be found in ELOG Port Configuration or you can use the following commands at a command prompt while logged into an account with administrator privileges:

    net stop elogd
    net start elogd

You can then access the ELOG webserver by opening a web browser on the system on which you've installed ELOG and pointing the browser to the loopback address of the system, which is 127.0.0.1. I.e., you can use https://127.0.0.1:8080, or you can use the fully qualified domain name (FQDN) of the system on which ELOG was installed. E.g. you could use https://a.example.com:8080, if the system was named a.example.com and you are using the default port for ELOG, which is 8080.

You will get a warning message from your browser regarding the security certificate, because it is self-signed rather than being signed by a recognized certificate issuing entity. You can continue without worrying about the certificate, however. The self-signed ELOG security certificate is in the ELOG ssl directory. You can purchase a certificate from a recognized certification entity to avoid browser warnings about the certificate. If you perform a web search on "purchase SSL certificate" you will get lots of links to places where you can purchase an authenticated certificate.

By default you can connect to the ELOG webserver from other addresses, i.e. you aren't limited to just accessing it from the system on which it was installed, unless you have a firewall blocking access to the address, in which case you will need to allow access by configuring an appropriate firewall rule.
