AudioDataCollector

This is a set of scripts to collect audio data from field sites and transfer them to host periodically.

Prerequirement:

Before running the main script, you should

1. Add all new nodes' IPs into CHILD_IP_POOL array in main.sh file;
2. Change the HOST_USER_NAME and HOST_IP to the corresponding values according to your own configurations;
3. On the host node, use "ssh-keygen -t rsa" command to generate the private and public keys (please do not set password when generating these keys), and APPEND the public key to the end of authorised_keys files located in the children nodes' "~/.ssh/" folder by "cat ~/.ssh/id_rsa.pub | ssh CHILD_USER_NAME@CHILD_IP 'cat >> ~/.ssh/authorized_keys'" command;
4. Similarly, log into each one of the children nodes, then use "ssh-keygen -t rsa" command to generate the public and private keys on each node (please do not set password when genering these keys), and APPEND the public key to end of authorised_keys file located in the host's "~/.ssh/" folder by "cat ~/.ssh/id_rsa.pub | ssh HOST_USER_NAME@HOST_IP 'cat >> ~/.ssh/authorized_keys'" command.

Done!!!
