Server IPv4 Address
Server IPv6 Address
Client IPv4 Address
Client IPv6 Address
Routed /64

Solaris and OpenSolaris IPv6 tunnel setup

Create /etc/hostname6.ip.tun0 file:
tsrc Client_IPv4_Address tdst Server_IPv4_Address up
addif Client_IPv6_Address Server_IPv6_Address up

Add the permanent IPv6 default gateway:
route -p add -inet6 default Server_IPv6_Address

(Tested on Solaris 10 5/09 and 10/09, OpenSolaris 2009.06 and 2010.02 preview snv_127)

Linux (RHEL / Fedora / CentOS) IPv6 tunnel setup

Create /etc/sysconfig/network-scripts/ifcfg-sit1 file:

DEVICE=sit1
BOOTPROTO=none
ONBOOT=yes
IPV6INIT=yes
IPV6TUNNELIPV4=Server_IPv4_Address
IPV6TUNNELIPV4LOCAL=Client_IPv4_Address
IPV6ADDR=Client_IPv6_Address/64

Add the following to /etc/sysconfig/network file:

NETWORKING_IPV6=yes
IPV6_DEFAULTDEV=sit1

(Tested with Fedora 11 and 12, CentOS 5.3 and 5.4)

FreeBSD IPv6 tunnel setup

Add the following lines to /etc/rc.conf file:

gif_interfaces="gif0"
gifconfig_gif0="Client_IPv4_Address Server_IPv4_Address"
ipv6_enable="YES"
ipv6_network_interfaces="lo0 gif0"
ipv6_ifconfig_gif0="Client_IPv6_Address prefixlen 128"
ipv6_defaultrouter="Server_IPv6_Address"

(Tested with FreeBSD 6.4)

pfexec zfs create -V 10g rpool/f12d0

Install Fedora 12 domU:
pfexec virt-install -n f12 -r 512 --vcpus=4 -f /dev/zvol/dsk/rpool/f12d0 -b e1000g0 --os-type=linux -p --nographics --os-variant=fedora11 -l http://fedora-12-mirror/fedora/linux/releases/12/Fedora/i386/os/

-n f12 – domU’s name
-r 512 – allocate 512 MB memory
–vcpus=4 – number of virtual CPUs allocated (make sure this number is lower or equal to the number of CPUs available)
-f /dev/zvol/dsk/rpool/f12d0 – ZVOL block device
-b e1000g0 – bridged networking to e1000g0 interface
-p – paravirtualized guest
–os-variant=fedora11 – “hack” until fedora12 OS-Variant will be integrated into xVM
-l http://fedora-12-mirror/fedora/linux/releases/12/Fedora/i386/os/ – replace fedora-12-mirror with a near Fedora 12 mirror, replace i386 with x86_64 for 64-bit domU

After you bring up the network, do a VNC installation.
Until xVM supports ext4 boot, make sure to create an ext3 /boot partition (or just a big ext3 / filesystem)

After installation, start the domU:
pfexec xm start -c f12
You will be presented the pygrub menu, just press Enter to boot.

Log into the domU and change the default timeout=0 to a different value (e.g. 5 seconds) in /boot/grub/grub.conf. Now you can use virsh start / shutdown commands.

To auto-start the guest on host boot:
virsh autostart f12

Tested on OpenSolaris 2010.02 preview snv_127.

pptpd-1.3.4-1.fc12.i386.rpm MD5 bdab201d70e78abe40f873d71880f718
pptpd-1.3.4-1.fc12.src.rpm MD5 ebd64f47b0a40a7585e22a11cc4e2890

If you get this error message:
Plugin /usr/lib/pptpd/pptpd-logwtmp.so is for pppd version 2.4.3, this is 2.4.4
just comment out logwtmp option in /etc/pptpd.conf and restart pptpd with service pptpd restart.

Username/password pairs used for pptp authentication should be placed in /etc/ppp/chap-secrets
# client server secret IP addresses
username * password

To supply a DNS server to PPTP clients, just add them to /etc/ppp/options.pptpd like ms-dns A.B.C.D.

To configure local and remote PPTP client’s IP address modify localip and remoteip options in /etc/pptpd.conf.

To enable pptp server at startup run chkconfig pptpd on.

Opted for geo-redundant version (automated nightly replication to other site) located in Zurich, Switzerland. Very fast speed from Europe and Qatar, good speed with US hosts. Very easy to use from Mac OS X, FreeBSD, Linux and Windows (rsync, ftp, scp, sftp, ssh, WebDAV). Direct integration in Finder, just use “Connect to Server” and enter the hostname address with https. On Linux and FreeBSD 6.x sshfs works like a charm. Easy to install on FreeBSD using ports, just cd /usr/ports/sysutils/fusefs-sshfs and run make install clean.
