Transparent layer 2 tunneling through EoMPLS on Nexus 7K

Hello,
Does anyone know if the N7K supports transparent layer 2 tunneling of control traffic (CDP, STP and VTP) over EoMPLS? I'm unable to find exact info about this in Cisco's documentation.
Here's the problem I'm having:
I have an EoMPLS virtual connect configured between a ME3600X switch and a Nexus 7K switch to extend layer 2 domain across two different sites. The virtual connect is up and running and passing traffic successfully between the CEs. However, I'm having problem with tunneling CDP traffic from the N7K end to the ME3600X end. CDP tunneling in the other way is working fine. i.e. CE1 connected to the N7K is able to see the other CE (CE2) in its CDP table; however, CE2 connected to the ME3600X is unable to see CE1 in its CDP table, which I believe is caused by the N7K not tunneling the CDP traffic through the EoMPLS VC properly.
Below is the config:
! CE1 is connected to N7K port e3/28.
! CE2 is connected to ME3600X port g0/24.
! N7K:

Folks,
I have this issue resolved.
There were reported bugs in earlier version of code for the ME3600X which dropped MSTP and RSTP BPDU's.
Also there are 2 different use cases for using the L2protocol command:
1, When creating a service instance between 2 devices that supports the L2protocol command use L2protocol tunnel (ME3600 to ME3600)
2, When creating a service instance between a deice that supports the L2protcol command and another device that does not support the L2protocol command use L2protocol forward (ME3600 - 2911 or ME3600 to non Cisco device)
I upgraded the s/w on the ME3600 to 15.3-2
Here is the working configuration between the ME3600 and the 2911
PE1 (ME 3600X)
int g0/1
port-type nni
switchport trunk allowed vlan none
switchport mode tunk
service instance 2 ethernet

xconnect 10.11.1.16 encapsulation mpls

Thanks for your help.

Transparent layer over something opaque

Hi I'm trying to put an image over a webcam video. Is it possible to put a transparent layer over the video so it makes the video form into a shape.
Like here's the webcam ->
|                    |
|                    |
Can I put a image layer over it that is transparent, that will show the background through? Like this ->
|              |___ <- this is an image layered over the webcam with the background visible.
|                    |
Thanks if anyone can lend me a hand.

Hi...
Looks like we are trying to do the same thing - unfortunately we don't know much about coding, so we don't quit understand what to do.
we would like to place an image on top of the webcamera
so that the image of whats is being recorded is behind this image.
is it possible?

Dont think RMi is HTTP tunneling through proxy firewall

Hi Guys,
Does anyone know how to monitor if RMI is using the option toHTTP tunnel through a proxy ???
Many of clients sit behind firewalls/proxies that enable HTTP only. I thought RMI would, as a default, use HTTP tunneling POST, RESPONSe methods to get through, but it does not.
Would that case be insted of using Naming.lokup("RMIServer"); that i should use
Registry reg = LocateRegistry.getResgistry(serverAddress, serverPort);
reg.lookup("RMIServer");
Any help would be greatly appreciated.

RMI doesn't have an option like that. Sockets do, and you get it for any socket including RMI by setting socksProxyHost and socksProxyPort.
The RMI HTTP tunnelling thing happens when there is an HTTP server at the server side. which redirects the request to an RMI server via rmi-cgi.cgi or the RMI servlet. It's automatic, as a fallback, and you can enforce its use via a system property which you can find in the Javadoc Guide to Features/Remote Method Invocation/Useful java.rmi system properties.

Can you set a layer to "Template" through script?

Hi there,
     I am creating a script to batch export multiple artboards as SVG, and setting a layer to "Template" will keep my unwanted paths from exporting. I am using Illustrator version 17.1.9(64bit)
Is there a way to set a layer to "template" through script?
Thanks!
Scott

You are correct on this, if I create a template Action let say called "template layer" I can call that with app.doScript("template layer", "folder"). After testing it does work... on my client where I have the Action, but I have a few other artist who will need to run this script.
EXAMPLE:
for (var i = 0; i < app.activeDocument.layers.length; i++)
    app.activeDocument.activeLayer = app.activeDocument.layers[i] ;
    if(app.activeDocument.layers[i].visible == false){
        app.doScript ("template layer", "NI");
The only other solution I can think of is putting all non-exportable objects on a layer, and call that layer "nonExport" and select all objects on this layer delete them, then export, then undo this action ... ewwww... sounds messy.
Cheers,
Scott

HTTP-Tunneling through Apache Plug-in

Hello,
has anybody experience with HTTP-Tunneling of requests to a WLS
4.5.1SP13 through an Apache-Webserver?
I'm not able to configure the apache plug-in from weblogic to act as a
reverse proxy for requests coming from a
Java Client Application.
Any Hints available?

Hello Jong,
HTTP tunneling will append ".tun" to your request.
For apache, you can use "MatchExpression" to proxy the mime type.
i.e: add the following line to your httpd.conf
MatchExpression *.tunThat is functioning. Thank you very much.
Another question:
What about HTTPS-Tunneling through an Apache-Server?
How can I get everything through?
Thank you
Remo
We don't support https from the bridge to the server yet.
JongWhat about using HTTPS-Tunneling between our Java client and the WLS
Stronghold plug-in and HTTP-Tunneling between the plug-in and the WLS?
If this is possible, how do I have to setup the stronghold?

Here is example code for HTTPS Tunneling through proxy(400 Lines of code

Here is the source for Https Tunneling that I have gotten working. It is based on Pua Yeow Cheong's JavaWorld Tip 111. Thanks to David Lord for providing the final breakthrough that I needed.
I have posted it here for anyone who wishes to use it. If you find any bugs, or write any improvements, please tack them onto the end of this thread.
I have been trying to tackle this problem for quite some time, so I hope this helps a few of you out there.
Lots of Luck,

BTW, if you are using an implementation in which
the http/https implementation recognises
the java.net.Authenticator properly, you can use
that framework to do basic/digest authentication.
I think Sun's JDK 1.4 supports both basic
and digest for both proxies and the actual end
site you connect via http/https, but I haven't
tested it to be sure. I know it works
with http/basic at the end host.
Today's Ob hack:

How to make the eyedropper sample non-transparent color of a transparant layer?

I have an image of a flower I am trying to paint.
I put the flower as the top layer at 50% opacity to use as a guide.
Then I am trying to paint on a layer below that.
I would like to be able to use the eyedropper on the original image but for it to pick up the full color and not the %50 opacity version of the color.
I saw this done in a demo but can't seem to figure it out.
I tried setting the eyedropper options to "All layers no adjustments" but it's still only picking up the lighter version of the color.
Any suggestions?

Another option might be to make a fully transparent layer on top to paint on, and get your color from a fully opaque layer below. I have painted with the Mixer Brush quite effectively this way, though it's not incredibly speedy.

GRE tunnel through asa no pptp, l2tp, ipsec

Hello!
can't understand how to configure GRE tunnel through ASA
i have one router with public ip, connected to internet
ASA 8.4 with public ip connected to internet
router with private ip behind ASA.
have only one public ip on ASA with /30 mask
have no crypto
have network behind ASA and PAT for internet users.
can't nat GRE? cause only TCP/UDP nated(?)
with packet-tracer i see flow already created but tunnel doesn't work

A "clean" way would be to use a protocol that can be PATted. That could be GRE over IPSec. With that you have the additional benefit that your communication is protected through the internet.

Considerations for an IPSEC tunnel through another IPSEC tunnel

Hi,
I am trying to ipmlement a IPSEC "tunnel through a tunnel" as follows:
ASA-1 ( inside network 10.10.10.0 /24 - outside network 1.1.1.1/30) to ASA-2 (outside network 1.1.1.2/30 - inside network 20.20.20.0/24)
This tunnel is fully functional.
Created a DMZ interface (2.2.2.1/30) on ASA-1
Created a DMZ interface (2.2.2.2/30) on ASA-2
Attached ASA-A outside interface to ASA-1 DMZ interface - inside network 30.30.30.0/24
Attached ASA-B outside interface to ASA-2 DMX interface - inside network 40.40.40.0/24
Created an ACL on ASA-1 and ASA-2 DMZ interfaces allowing ESP,IKE traffic
2nd tunnel not working!
Questions
Should I add the DMZ /30's to the crypto map of ASA-1 and ASA-2 (I did, and it did still not work)
Should there be a route statement for the /30's on ASA-1 and ASA-2, or should the default GW be sufficient?
Any and all help will be appreciated!

Transparency layer with embedded R

I probably badly misunderstand the ORE transparency layer - as demonstrated on the following example.
I have a table X, that can be accessed from R client.
> summary(X)
       X                Y
Min.   : 1.00   Min.   :0.000
1st Qu.: 25.75   1st Qu.:4.686
Median : 50.50   Median :5.658
Mean   : 50.50   Mean   :5.248
3rd Qu.: 75.25   3rd Qu.:6.234
Max.   :100.00   Max.   :6.644
However using ore.doEval leads to Error: object 'X' not found
Note that the language setting is only to get message in English and has no other effect.
> ore.doEval(function() {Sys.setenv(LANG = "en"); summary(X)}, ore.connect= TRUE)
Error in .oci.GetQuery(conn, statement, data = data, prefetch = prefetch, :
ORA-20000: RQuery error
Error in summary(X) :
error in evaluating the argument 'object' in selecting a method for function 'summary': Error: object 'X' not found
ORA-06512: in "RQSYS.RQEVALIMPL", Zeile 104
ORA-06512: in "RQSYS.RQEVALIMPL", Zeile 101
How can I access data from a table in embedded function? Do I have to use ore.tableApply()?
any help appreciated.
thx,
Jaromir D.B. Nemec

To access a table directory, use ore.tableApply. Although ore.doEval does not explicitly accept data from a dedicated input argument, it's possible to retrieve data from the database using ore.sync and ore.pull within the function:
ore.doEval(function() {
library(ORE)
ore.sync(table = "X")
dat <- ore.pull(ore.get("X"))
summary(dat)}, ore.connect = TRUE)
Another approach is to pass the data (table) as an argument to the ore.doEval function:
ore.doEval(function(dat) {
library(ORE)
summary(dat)}, dat = X, ore.connect = TRUE)
Check out this blog post for more information and best practices on the use of ore.doEval and ore.tableApply.

How to make a semi-transparent layer?

Hello everyone,
I am making my own website with Dreamwaver. I am a totally
new user and have no IT background. So could anyone here kindly
help me with my question:
In the main page I would like to use two layers with images
inserted. The second one will be a semi-transparent image which is
made in Fireworks. I would like to let this layer cover the first
one. Because it's semi-transparent, so i should still be able to
see the underlying image... I did all this, but finally in the IE
the second layer is NOT transparent at all.
I don't know where the problem is. Please, if anyone knows
the solutions or have any suggestion, let me know!
Thanks!
Inca

I'll show it to you my way:
1. Type the text and click the layer mask icon. The layer mask should be all white and have a small border. That indicates the mask ist active.
The foreground color should be black and the background color white.
2. Choose the gradient tool. Open the gradient window. Choose the first gradient, "foreground to background" = black to white.
Change the white color to gray.
3. Check the layer mask > is it active?
Apply the gradient from right to left over your text.
See the thin line in the screenshot.
4. On your layer mask appears the gradient, left starting with gray and right ending with black.
The advantage of this method is that you can change your text without modifying the gradient.
The black color on the layer mask hides the text, the gray color makes the text more or less visible and white color means full visible.
Hope it helps.

Advanced Network Question - SSH tunneling through time capsule

Hi!
I have a small question. I just got a time capsule the other day and things are working great with it. At home, internet speeds are what they should be and everything is fine. I replaced it with a linksys, which I consistently got 6.5/1 up. After replacing it, I'm now getting 7.5 down/1mbps up, which is what I am subscribed to.
I used to ssh into my linux box and tunnel web traffic over SSH so when I'm on the road, other's can't sniff my traffic. Basically, I setup firefox to use a socks server, then ssh into home with a dynamic port mapping.
On the linksys (wrt54g), this worked great, and the speeds were acceptable (about 1mbps down/1mbps up). However, after switching the linksys with the time capsule, it seems like the speeds have slowed down tremendously. I'm now getting about 200k down and 1 mbps up when I ssh and tunnel web traffic through my home.
I know that this isn't anything people normally do, but it works great and prevents people from spying on my web traffic when I'm away from home. I was just wondering if anybody has any ideas on why it might be slower now that I replaced it with the time capsule.
Thanks!

Hello H Salk. Welcome to the Apple Discussions!
Enabling NAT on any Internet router, not just the AirPort & Time Capsule, will affect data transfer rates (in both directions) to devices connected either by wire or wireless to that router.

Value not reflecting into the transparent table when checked through se11

Hi friends. i am using the following code to add data to a transparent table already creted by me.Now i am adding data to it through a ABAP program.It is displaying the output when I execute it but the new record added in the program is not saved itno the table actually.my code is :
REPORT ZWRITE_DATA.
tables zlfa2.
move 'achal' to zlfa2-field_name_1.
update zlfa2.
select * from zlfa2.
write / zlfa2-field_name_1.
endselect.
the above code is not showing the value 'achal' in it.and also no error message is being displayed.

Hi,
Commit work saves the changes done into the database. Using COMMIT WORK statement in your program have below mentioned effect:
Calls the subroutines specified by PERFORM ... ON COMMIT
Executes asynchronously any update requests (see CALL FUNCTION ... IN UPDATE TASK) specified in these subroutines or started just before
Processes the function modules specified in CALL FUNCTION ... IN BACKGROUND TASK
Resets the time slice counter to 0.
Ensures that the locks of the SAP locking concept are handled in accordance with its SCOPE Parameter.
Executes a database commit on all database connections
Closes all open database cursors (OPEN CURSOR) on all database connections
Releases all database locks on all database connections

Cannot establish site-site vpn tunnel through ASA 9.1(2)

Hi,
We use ASA 9.1(2) to filter traffic in/out of our organisation. A dept within the organisation also have a firewall. They want to establish a site-site VPN tunnel with a remote firewall. We have allowed full access between the public address of the dept firewall and the remote firewall and full access between the remote firewall address and the dept firewall address . We do not use NAT.
The site-site VPN tunnel fails to establish.
The dept sysadmin has requested that we enable IPSec Passthrough. From my reading this will not make any difference as we allow full access between the firewalls in both directions. Is that correct?
Has anyone encountered issues with ASA 9.1(2) interfering with site-site tunnels?
Regards

>The dept sysadmin has requested that we enable IPSec Passthrough. From my reading this will not make any difference as we allow full access between the firewalls in both directions. Is that correct?
Yes, in that case, no IPsec-pass-through is needed. All you need is (in both directions):
UDP/500
UDP/4500 (also if you don't use NAT, the remote gateway could be located behind a NAT gateway)
IP/50
for testing ICMP/Echo
If you allowed full IP-access between these two endpoints, it is more than enough.
When they start testing, do you see a connection on your ASA. There should be at least UDP/500 traffic.
Can the two gateways ping each other?

Photoshop CS4 transparent layer only, no picture.

When I open a jpg, bmp or any other picture file in photo shop all that appearsis the checkerboard tranparent layer. Thee is no picture to edit. What is wrong with photoshop? It also takes forever for the blank transparent picture to load. Windows Vista.

I found the solution after trying everything else including completely uninstalling Photoshop and deleting the files it left behind, then reinstalling did not work either. I then copied the color settings and PSP files from another computer, started Photoshop, opened a picture and everything is working fine now.
I would suggest anyone else with this problem just needs to get a copy of the files from someone else and or keep a back up of the PSP and color settings in a back-up folder as I have now. Adobe should consider a restore feature that automaticaly saves restore points. There are likely other Adobe CS4 programs that also need to back up settings.
