DRAFT

Usually the typical Telecom Italia PPPoE or PPPoA ADSL connection with dynamic IPv4 only was authenticated with “aliceadsl” as user and password, now with bran new credential along IPv4 the endpoint router advertise a IPv6 /64 class (always dynamic).

username: adsl@alice6.it password: IPV6@alice6

And now IOS configuration:

- ATM inteface:

interface ATM0/0/0
no ip address
atm restart timer 300
no atm ilmi-keepalive
dsl operating-mode auto
hold-queue 100 in
!
interface ATM0/0/0.1 point-to-point
pvc 8/35
vbr-nrt 380 380
oam-pvc manage
encapsulation aal5mux ppp dialer
dialer pool-member 1

- Dialer inteface:

interface Dialer0
mtu 1492
ip address negotiated
ip nbar protocol-discovery
ip flow ingress
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer-group 1
ipv6 address autoconfig

no cdp enable
ppp authentication chap callin
ppp chap hostname adsl@alice6.it
ppp chap password 0 IPV6@alice6
ppp pap sent-username adsl@alice6.it password 0 IPV6@alice6

- Route configuration:

ip route 0.0.0.0 0.0.0.0 Dialer0
ipv6 route 2000::/3 Dialer0

You can check with following command:

route01#sh ip int brief | sec Dialer0
Dialer0                    XXX.XXX.XXX.XXX    YES IPCP   up                    up
route01#sh ipv6 int brief | sec Dialer0
Dialer0                    [up/up]
FE80::1
2A01:2003:xxxx:xxxx::1

You can discover your /64 assigned class with:

route01#sh ipv6 int di0 | sec Global
 Global unicast address(es):
 2A01:2003:xxxx:xxxx::1, subnet is 2A01:2003:xxxx:xxxx::/64 [PRE]
 valid lifetime 2591993 preferred lifetime 604793

I’ve left out NAT and other further configuration.

Remote Desktop Licensing service to fail to start, with error code %%-1073672191.

The Terminal Services Licensing service cannot start. The following error occurred: Can't initialize Cryptographic - error code 5.

Sometime happens a problem with Remote Desktop Licensing services not starting. The Terminal Licensing MachineKeys have permissions for Administrators and/or TermServLicensing  but the service starts using the “Network Service” account… Why??????

You can fix the problem adding Network Service account (read only privileges it’s ok), on follow directory (you can force ownership propagation for reapply the correct privilege tree):

C:\\Documents and Settings\\all users\\Application Data\\Microsoft\\Crypto\\RSA\\MachineKeys

Then the service start, correctly.

For further information you can take a look at microsoft KB:

Default permissions for the MachineKeys folders: http://support.microsoft.com/kb/278381

http://msdn.microsoft.com/en-us/library/bb909654%28v=vs.90%29.aspx

You can disable this feature by adding this to your notes.ini and restarting the Domino server. PLATFORM\_STATISTICS\_DISABLED=1

Consider a restart net services /etc/init.d/network restart but is not strictly required.

Optimistic Algorithm is aggressive enough to move to a higher rate but yet tries to conservatively capture the fluctuations of the RSSI. It starts with the highest possible rate and then decreases till the rate can be supported while periodically transmitting packets at higher rates and computing the transmission time. The optimistic rate algorithm always looks to achieve highest throughput while sacrificing noise immunity and robustness.

Rate Algorithm selection Conservative Algorithm is less sensitive to individual packet failure as it is based on a function of number of successful and erroneous transmission/retransmission over a sampling period. It steps down to a lower rate after continuous packet failure and steps up after number of successful packets. The conservative rate algorithm provides the best case stability / robustness, but may compromise maximum throughput. It is recommended to select conservative rate algorithm when the signal strength is low due to noisy environment or link distance.

EWMA Algorithm is trying to move to a higher rate but is continuously monitoring the packet failure counters. The Exponential Weighted Moving Average (EWMA) Algorithm (also known as minstrel) is a hybrid of the Conservative and Optimistic Algorithm. It is the compromise for most of the wireless network use cases.
