CalDAV and CardDAV Server

Calendars and address books are available for both local and remote access, possibly limited through authentication policies. They can be viewed and edited by calendar and contact clients on mobile phones or computers. radicale.org This is my working setup on Linux Debian with the python uwsgi server and Nginx. I could not get the database to work, so the backend is file based!

Linux Containers

Linux Containers provide a Free Software virtualization system for computers running GNU/Linux. This is accomplished through kernel level isolation. It allows one to run multiple virtual units simultaneously. Those units, similar to chroots, are sufficiently isolated to guarantee the required security, but utilize available resources efficiently, as they run on the same kernel. apt-get install lxc bridge-utils debootstrap First we will setup our Bridge: Linux:bridge-utils /etc/fstab cgroup /sys/fs/cgroup cgroup defaults 0 0 mount -a LXCDIR=/var/lib/lxc cd $LXCDIR nano vm0.

Mail Server Fingerprint

This is useful when you need the fingerprint to identify via TLS Get the raw certificate: echo Q | openssl s_client -connect mail.example.com:443 Copy and paste the scribble from —–BEGIN CERTIFICATE—– to —–END CERTIFICATE—– to a file called cert.pem. Including —–BEGIN CERTIFICATE—– as first and —–END CERTIFICATE—– as last line. Generate the SHA1 fingerprint by issuing following command: openssl x509 -in cert.pem -sha1 -noout -fingerprint

ssh authorization

Create a public ssh key, if you haven’t one already. Look at ~/.ssh. If you see a file named id_dsa.pub then you obviously already have a public key. If not, simply create one. ssh-keygen -t dsa ItemMake sure your .ssh dir is 700: chmod 700 ~/.ssh Get your public ssh key on the server you want to login automatically. scp ~/.ssh/id_dsa.pub remoteuser@remoteserver.com: Append the contents of your public key to the ~/.
