Linux issues

	apt-get	`security.ubuntu.com` does not work, so no security updates. Workaround: use local mirror `nl.archive.ubuntu.com` for security updates.
	Pear Net_Socket	Does not like IPv6 addresses, wrote patch.
	ntp	`ntp.ubuntu.com` does not work. Use our own NTP server `graham.terena.org`
	ntp	dumps core without IPv4 loopback address. Keep legacy 127.0.0.1 address
	Confluence LDAP auth via IPv6 = b0rked	Workaround: use IPv6 hostname: `ldap.ipv6.terena.org`
