rosbag-rotate

Scripts to use logrotate with rosbag and push data to a remote server

Configuration

SSH

1. (optional) Create a new account on the remote machine, and restrict it as desired
2. On the robot machine, create a new keypair with a blank passphrase

ssh-keygen -f ~/.ssh/id_log_copy -C "Automated remote backup"

3. Configure the local machine to use this new key when accessing the remote machine. Open up ~/.ssh/config and add

Host [REMOTE_MACHINE]
  IdentityFile ~/.ssh/id_log_copy
  # if you created a new user, add the next line too
  User [USER]

3. Copy the public key to the remote server

ssh-copy-id -i ~/.ssh/id_copy_log.pub [USER@]REMOTE_MACHINE

4. On the remote machine, copy rrsync to somewhere on your path and make it executable. This is the path to rrsync on ubuntu - other systems may have it elsewhere.

gunzip /usr/share/doc/rsync/scripts/rrsync.gz -c > ~/bin/rrsync
chmod +x ~/bin/rrsync

5. (If you created a new user for backups and want to handle security restrictions through the user, skip this step) Restrict the newly created key pair to only rsync by prepending the following to the line for your new key in the remote machine's ~/.ssh/authorized_keys

command="$HOME/bin/rrsync ~[LOG_DIR]",no-agent-forwarding,no-port-forwarding,no-pty,no-user-rc,no-X11-forwarding

Note: this, and the key should both be on a single line.

Logging

1. Create a local directory for logs to go (we'll call it LOCAL_LOG_DIR)
2. Make sure python-crontab is installed: sudo pip install -U python-crontab
3. Run the config script:

cd [path to rosbag-rotate]
./setup.sh LOCAL_LOG_DIR REMOTE_MACHINE LOG_DIR
