Append the provider configuration to /etc/ppp/ppp.conf:
provider:
set device PPPoE:<interface>
set authname <PPPoE username>
set authkey <PPPoE password>
set dial
set login
add default HISADDR
enable lqr echo
enable dns
nat enable yes
set redial 2
Replace <interface> with your network interface towards the PPPoE server. Start the PPPoE client, as root: /etc/rc.d/ppp start
Enable PPPoE client at startup, append to /etc/rc.conf:
ifconfig_<interface>="up"
ppp_enable="YES"
ppp_profile="provider"
ppp_mode="ddial"
Start the PPPoE client with /etc/rc.d/ppp start as root. The PPPoE interface is usually tun0.

After you create a Regular Tunnel at Hurricane Electric’s tunnelbroker.net you will receive the following informations:
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)

Create a 10 GB ZVOL for storage:
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.

I’ve build a Fedora 12 Poptop rpm:
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.

Create a new Boot Environment:
pfexec beadm create devel
Mount the new Boot Environment:
pfexec mkdir /mnt/devel
pfexec beadm mount devel /mnt/devel
Use the dev publisher:
pfexec pkg -R /mnt/devel set-publisher -O http://pkg.opensolaris.org/dev opensolaris.org
Update to the latest bits:
pfexec pkg -R /mnt/devel image-update -v
If everything went fine (after you read the Release Notes), activate the new BE:
pfexec beadm activate devel
Reboot:
pfexec shutdown -y -g1 -i6
Did this remotely. After reboot, system was up and running, including all xVM domU autostarted.

Internet service in Egypt, the UAE, India and other counties in the region was interrupted today when submarine cables in the Mediterranean Sea failed.
Cause of the failure is not known at this time, says operator Reliance GlobalCom. A total of three cables linking Italy and Egypt went down. A ship has been sent out to fix the problems.
Currently, services are being rerouted to backup cables and satellites. As rerouting measures fully kick in, services are expected to improve by early Saturday morning.
This isn’t the first time that cable service to the region has failed. Earlier this year, five separate undersea cables were cut between late January and early February, interrupting service to a number of countries.
There’s likely to be some serious failure analysis involved if we see some more pipes go off-line in the next week.
