Many locations have IP addresses that get changed frequently. In order to be get remote access to your Oscar server, you need to install a Dynamic DNS client. This can be on a workstation, router or server. The workstation is probably easiest, but the workstation must always be on. Router installation is good, but not supported by all routers.
I use DynDNS and DNS2GO. This post describes setting up the DNS2GO client on the Oscar Ubuntu server. This was done for Ubuntu 12.04 and 13.10 servers.
Download Debian client from http://www.deerfield.net/download/dns2go/linux/index.htm and save in home folder.
For Ubuntu/Debian, use dns2go-2.0.tar.gz
Unzip file
tar -zxvf dns2go-2.0.tar.gz
Change to unzipped directory
cd dns2go-2.0
Check for location of libc library (see below)
find | grep libc.so.6
Install the DNS2GO client
sudo ./INSTALL.sh
Error – Could not find glibc library
Solution: change INSTALL.sh to check current location of libc library (see below)
for Ubuntu 13.10 /lib/x86_64-linux-gnu/libc.so.6
This will run the installer for the DNS2Go client and copy all necessary files to the correct locations. The executable is installed in /usr/local/bin, documentation in /usr/doc/dns2go-2.0, manual pages in /usr/local/man and conf file in /etc/dns2go.conf
To finish the installation, type:
sudo /usr/local/bin/dns2go
You will be asked if you want to create the dns2go.conf file, select Yes.
You will now be asked if for your domain name and registration key (if you do not have your key, do not run this yet).
eg. myclinic.dns2go.com
Add program ( /usr/local/bin/dns2go ) to /etc/rc.local to execute automatically when the server starts
sudo nano /etc/rc.local
/usr/local/bin/dns2go
