These are the steps required to set up a new FeministWiki Debian server. | These are the steps required to set up a new FeministWiki Debian or Ubuntu server. The guide assumes that you're comfortable connecting to a host with SSH and using the shell. It also assumes some basic knowledge on how to set up SSH keys and configure key-based access between machines. | ||

=== Tighten security of SSH access === | |||
Port 22 will get lots of malicious login attempts. It's a good idea to change the SSH port, and also to disable password authentication in favor of key-based authentication. Both can be done by editing {{C|/etc/ssh/sshd_config}}. | |||
Before restarting the SSH service, make sure you've actually added your public key (the contents of {{C|~/.ssh/id_rsa.pub}} on your computer) to {{C|/root/.ssh/authorized_keys}} on the server, or you'll lock yourself out. | |||
=== Set up firewall === | |||
For now, block everything but SSH. | |||
apt-get install ufw | |||
ufw allow proto tcp to 0.0.0.0/0 port <ssh_port> | |||

Some of the commands here assume that you've set up ssh access from the old server into the new server. For this to work, copy the contents of {{C|/root/.ssh/id_rsa.pub}} on the old server, and '''append them as an additional line''' onto {{C|/root/.ssh/authorized_keys}} on the new server. | |||
