After "without Accelerator crypto engine" No. VPN PLUS
Hello
In my test harness, I have a CISCO with a Council AIM-VPN/BPII-PLUS 1841, everything worked well, until I see the difference with and without the accelerator
Sins as soon as IOS told me he'll change accelerator SW instead of HW Accelerator, I can't make it work anymore.
I have a copy of the full configuration of work before I did, I put it back on my router but still WITHOUT a VPN.
Any idea what does not work?

You disable the VPN tunnel after disabling the VPN accelerator card?
You need to do:
delete the ipsec cry his
clear the isa cry his
Then build the interesting traffic again and please share the output of:
HS cry isa his
HS cry ipsec his
If the VPN is not upward, you can enable debug and share the output:

use of crypto engine - how to measure?
Hello
I'm looking for a command or another way to measure the CPU usage in a card crypto engine?
Is it possible to check how the vpn tunnels crypto engine effect processor traffic? Why I need? For example if I had 100 tunnels with certain characteristics of traffic, I need to know if I can add new tunnels it or I need to buy a new router to put an end to any new added VPN.

Przemek
Przemek,
I am afarid the answer still will not be uniform :-)
In your case, you run embedded cryptographic engine (or at least what I remember of NETGX).
IKE sessions will be processed by the processor and only IPSec flows processed by the encryption engine.
More than sessions IKE - more stress on the control plan. That is to say that the CPU high can still affect even if engine cryptographic tunnels is relatively inactive.
You might get some indication at the beginning of 'show crypto isakmp stat' but actual counters to monitor will depend on your configuration.
There is also a finite number of sessions can be sent to the crypto engine.
From a realistic point of view, you should follow the sheets (marketing) insofar as the scaling of goes.

How can I download firefox without the search engine, it automatically takes me when I open a new tab. ?
You can use the SearchReset extension to reset preferences to default values.
Note that the SearchReset extension runs only once and then uninstalls automatically, so it will not appear on the page "> Firefox Add-ons" (topic: addons).
If you do not keep the changes after a reboot or have problems with preferences, see:

A motor with encoder closed loop. Can I connect an other encoder without using an engine?
Thanks to LabVIEW with a PCI-7332 and an UMI7774 interface to control a stepper motor with encoder feedback. System is configured in closed loop for the control mode. You will need to add a different encoder to the system without attaching a motor. I'm validation of encoders to each other. Is this possible? Should what kind of latency I expect? I have attached a simple vi. Need to buy one before the answer.
Thank you
You can just plug the second encoder to the second slot without an engine it. Then you can use reading encoder Position.flx to read its position or do whatever you want with it. What about latency times, how are you trying to go under?

L2 VPN and SSL VPN-Plus server on the same edge is not possible
Hello
Today, I was busy trying to test the L2 VPN functionality and I got an error message that I had no right to allow the 'L2 VPN server' when the SSL VPN-Plus feature is enabled on the server VPN of L2.
Is it possible that these two can run concurrently?
And what is the reason for which (technical) why it does not work, or may not work at the moment?
The L2 VPN as well as the VPN-Plus SSL enabled overall feature works very well elsewhere, but with the server it does not work...
OK, I should have been more precise here. It is using the same service on the GSS. You cannot activate both at the same time. This is how it is. Maybe this will change later.

SSL VPN-Plus Mac client? Installation abandoned
Hi all
I've set up my VPN gateway - more SSL...
I downloaded with my gw the windows client and the Mac client.
I installed my windows client, and I am able to connect to my vpn - ssl.
But I'm not able to install the Mac client on my two Mac OS X Maverick, he refuses to be installed (installation was interrupted).
Do you know if there is a compatibility issue with Mac OS X Maverick (10.9)?
Is it possible to download this client directly without being forced in to do through my gateway?
Thx for your support.

External keyboard works only after the restart with Port Replicator III Plus
The problem is that when I start the laptop, the external PS/2 keyboard does not work. When I reboot keyboard this one turns around and then I can use it.
This problem occurs on a laptop Toshiba Tecra with an Advanced Port Replicator III Plus. I used several keyboards, so this isn't the problem. I changed a value in the bios which is used for devices USB (mouse/keyboard). I disabled the option, because I use a keyboard and a PS/2 mouse, but the problem is not resolved. I hope someone has an answer to this problem.
Hello
It will be interesting to know what model Tecra you use. Is it perhaps Tecra A6?

After moving to Windows server 2012 VPN connection error
Hello world!
Recently, I upgraded my Windows Server 2003 SB server to a new server running Windows Server 2012.
I started from scratch by creating a new domain, user, accounts etc.
The new server is using the same IP address as the old server.
Since then, I can't connect through the VPN. I have already added the role of remote access on the new server.
When I try to connect to my Windows 7 laptop, I get this error:
"Error 800: the remote connection does not because attempts VPN tunnels failed." The VPN server is maybe inaccessible. "If this connection tries to use an L2TP/IPsec tunnel, the security settings required for IPsec negotiation is may not configured properly."
Any help with this is appreciated.
Hello
The question you posted would be better suited in the TechNet Forums. We have a separate team working on the server problem, so I would recommend posting your query in the TechNet Forums.

USB Ports dead after undocking and anchor W510 in Minidock Plus series 3
Hello
just a new W510 (Win XP 32) for a user customized and installed it on his desk. Everything worked fine except for one thing.
I start the NB in the Docking Station with an external keyboard and mouse (original IBM/Lenovo) attached.
Works very well.
Then I disconnect the laptop (there is no button or menu entry for disconnection, it is enough to press the button to eject the NB).
Laptop still works fine.
Now, I put the NB in the dock. External LCD display shows regular office but external keyboard and mouse no longer works. The mouse didn't even power (no lights).
I checked all USB ports--> dead.
If I plug the mouse or the keyboard to the usb port of the NB they get power, but do not work.
If I reboot the NB, all is well again.
Do I have to install a special plug-ins to allow equipment nd "reconnect"?
Thank you
Concerning
Mith
just visited the user and checked the NB again.
Guess what happened? Disconnect and reconnect worked.
It is not that I did not wait long enough to install all the drivers for the last time.

The repro steps:
- Go to tools-> area Administration. Add a new field called MonIdentificateur with logic type UNIQUEIDENTIFIER. Apply and save the changes.
- Go to tools-> Preferences, then-> model-> relational data Modeler. Go to the group box of basic column data Type and set Domain = MonIdentificateur. Apply the changes.
- Create the new entity and enable the option 'create a surrogate key. Apply the changes.
- Engineer to the relational model with the default settings.
Expected result:
Data type of the column Entity_1_ID is of type UNIQUEIDENTIFIER
Actual result:
Data type of the column Entity_1_ID is of type CHAR
The problem was with the relational model. I created before choosing default Site RDBMS and it was created for Oracle DB. Change the Site RDBMS option within the relational model solved the problem.

Cisco 1921: aboard the hw module not used?
Hello
I have a 1921 Cisco who has an IPSec connection to the outside, but despite this, it seems that the "Accelerator" hw module is not used because the stats are all zeros (see below). Also, I can see that the module is enabled (using the crypto engine see the brief), but the router connection to the sw module (with the help of see the crypto engine connections flow)
What could that be caused by?
See you soon,.

Hey, Sylvain.
If you are looking for suite-B on hardware support, then you must upgrade to train 15.2 (4) M.
See the release notes for more details
http://www.Cisco.com/en/us/docs/iOS/15_2m_and_t/release/notes/15_2m_and_t.PDF
"IPSec required with Suite B algorithms are now supported by the hardware encryption engine on the.
Cisco Integrated Services routers generation 2:800 Series, series of 1900, 2901, 2911, 2921, 2935R,
3925th and 3945TH, which each integrated hardware acceleration of encryption VPN.
Suite B necessary includes four suites in the user interface of encryption algorithms to use with IKE
and IPsec, which are described in RFC 6379 and RFC 6380. Each suite consists of a cipher
algorithm, a digital signature algorithm, an algorithm agree key and a digest of hash or message
algorithm.
Suite B provides an improvement in the overall security of Cisco's VPN IPsec, and it allows additional
Security for large scale deployments. Suite B is the recommended solution for organizations that need
Advanced security encryption for the wide area network (WAN) between remote sites.
To get detailed information on the features of Cisco IOS IPsec to 15.2 (4 M) that support the Suite B"

You could do with some remote Busters tools such as remote desktop or some flavors of VPN. Both would require a tunnel through the router in the office.
