GandynR (test version)
=======
### Automatic DNS update for Gandi.net hosting. With R. And ssh.
* Before reading this, check first [gandyn](https://github.com/Chralu/gandyn) : nice and working python script.
* So, why coding a new script if [gandyn](https://github.com/Chralu/gandyn) works well ?
* Personal learning + rainy day. And to see if it was possible to do this with `R`. And also :
* Adding small security check. Sort of : try a ssh connection to itself to check new retrieved IP.
* A bit more minimalistic. Dumber ?
* If something goes wrong, nothing is done, logs are written in one file.
* Clean output.
```{sh}
randy@rpi ~/gandynR $ cat gandynR-log.txt

Wed Jul 2 19:44:45 2014:IP not changed. Old:101.62.189.138 New:101.62.189.138
Wed Jul 2 19:50:44 2014:IP has changed. Old:101.62.189.138 New:101.62.189.139
```
### to do :
* testing
* adding external mail warning support with `sendMailR`
### Prequisites
* Make a backup of your zone versions before using this script.
* Be sure you can SSH your own server from itself without password. (See Refs below)
* Enable XML-RPC interface for your domain on [gandi](https://gandi.net) and get an API key.
* Install R library `XMLRPC`. In a `R` console :
```{r}
source("http://bioconductor.org/biocLite.R")
biocLite("XMLRPC")
```
* Clone `gandynR` git project somewhere on your web server: `git clone https://github.com/fxi/gandynR.git`
* Rename `gandynR-config.exemple.R` to `gandynR-config.R` and complete it with these `R` lines :
```{r}
aKey <- 'yourApiKey03oinr3508fn5hohoho' # your personal gandi api key
dName <- 'yourDomainName.com' # your domain name
userId <- 'Randy' # ssh user id
sshPort <- '12123' # default ssh port is 22
logDir <- '~/myGandynR/' # directory where to write messages AND outputs.
```
* try it : /usr/bin/Rscript /pathTo/gandynR.R /pathTo/configDir/
* Set a cron action :
* `crontab -e`
* Add this line :
```{sh}
*/5 * * * * /usr/bin/Rscript /pathTo/gandynR.R /pathTo/configDir/ >/dev/null 2>&1
```
* `>/dev/null 2>&1` part : don't email output.
* Add `MAILTO="[email protected]"` at the beginning of your crontab if you want a useless mail every 300 seconds.
