Virtual machine specifications

The virtual machine runs on top of Xen and has:

The FSF sysadmins control a firewall that is outside of the VM. So we need to contact them to open new ports.

At least the following ports have been opened:

Port Transport Service software
22 TCP SSH OpenSSH
25 TCP SMTP OpenSMTPD
53 UDP DNS Bind 9
80 TCP HTTP Apache
143 TCP IMAP Dovecot
443 TCP HTTPS Apache

Software:

Disribution: Trisquel
Boot setup: Encrypted /, GRUB decrypts opens the encrypted rootfs and loads the kernel and initramfs from it which then opens the encrypted rootfs again with a key. The encryption is now handled transparently (outside of the VM? in btrfs?).
