Add a client to tykbackup

The following steps should be followed to add a new client to TykBackup:

Add SSH key

Make sure the folder /root/.ssh exists, and run the command below to allow the backup server to log in as root using ssh:

echo "ssh-rsa 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 root@backup.tyknet.dk" >> /root/.ssh/authorized_keys

Configure sshd

Also change PermitRootLogin no to yes in /etc/ssh/sshd_config, the (sensible) default in FreeBSD is to not allow root logins over ssh.

Consider disallowing password logins and use key login only, and always firewall ssh.

Configure firewall

Allow SSH logins from backup.tyknet.dk to allow the backup server to login.

Install rsync

Dirvish uses rsync, so install the port /usr/ports/net/rsync/ with the default options:

sudo portmaster /usr/ports/net/rsync/
