Several Tunnels with the same distance network &; destination in cryptographic maps
This maybe a newbie question, but I don't have production systems and don't really have a way to test our properly. We have an ASA 5520 with several tunnels from site to site. We already have a tunnel with one of the remote networks in 10.100.90.14. We have this IP on a subnet configured as remote network and the destination address in the card encryption. We also exempt rules NAT in place for our local network with the 10.100.90.14 address as the destination.
We have another tunnel that must be built and who will have a different address peer, but that requires a large number of subnets and at least we'll have the same remote network/destination address in the map encryption and VPN tunnel that we already have in place.
Is this possible to do with a tunnel of site to another without a static or dynamic NAT to a different IP address?
I know, with physical networks, that it is impossible because of the static routes that are in place, but with the ipsec tunnels I'm not sure how it works, and as mentioned, I'm not able to test it.
Any guidance would be appreciated.

The acl crypto map defines interesting traffic. If you have the same destination IP address, IE. 10.100.90.14 then if the source IE. the IP address of the client on your network is identical for the two tunnels, then no, it won't work and you will need to make some sort of NAT for one of the tunnels.

Twice NAT on Site at the tunnel with the same private networks.
Hello
Currently, I am trying to configure a Site to Site tunnel between an IOS router and an ASA 5505 running 9.1
When deprived of the IOS router subnet was 10.0.0.0/24 and the subnet private SAA was 172.16.1.0/24, it connected properly.
I'm now putting in place where the two private networks is 10.0.0.0/24 and objects network created, edited the ACL for interesting traffic and created the rule of NAT translation and twice, but the tunnels are not coming. I was hoping someone could shed some light on where I'm wrong.
There are route it (R1) IOS and ASA (F2). Between them is an Internet addresses asking the router which is just set up to allow both sides to achieve their WAN.
R1 and F2 have private network (10.0.0.0/24) need to communicate. Twice NAT can be done on the ASA to allow this, but I have to do something wrong. The way I understand it, is that the R1 should see traffic coming from 10.51.0.0/24 and send to this traffic. The ASA will have this traffic and the inside network should see it coming entering as 10.50.0.0/24. If F2's private network communicates with 10.50.0.0/24, and the private network R1 sends traffic to 10.51.0.0/24.
I turned on "Debug crypto ipsec" and "debug crypto isakmp" but no output is appear or give any indication that she is trying to establish anything.
Any help would be greatly appreciated! Thank you!

Here in nat rule u use subnet PARTNER_PRIVATE, which is the same as a local, so the devices never send this traffic to the ASA, cause they know that this subnet (10.0.0.0/24) is in their local subnet. Therefore, you must write the nat rule in this way (i.e. the change of objects Web places):
nat (inside,outside) source static PRIVATE PARTNER_VPN_OUTBOUND destination
static PARTNER_VPN_INBOUND PARTNER_PRIVATESo the hosts on the subnet behind ASA will see the hosts on the subnet behind SRI as 10.50.0.0/24 and trying to reach the subnet behind SRI, you must use the 10.50.0.x one-to-one wich addresses correspond to 10.0.0.x it.
In addition, your proxy-acl on asa must use post-nat addresses, which should look like this:
IP 10.51.0.0 allow CRYPTO access list 255.255.255.0 10.0.0.0 255.255.255.0

Cisco ASA cannot create several tunnels at the same address in hand?
We have several remote sites with Linksys WRVS4400N and Smoothwall firewall/vpn devices. I need these sites to be able to connect to several tell-contiguous subnets to our main office. This was done easily with smoothwall and linksys. You create a separate tunnel for each subnet, and voila, you're done. However, when I tried this with our ASA newly installed, it won't let me create several tunnels at the same address of the remote peer. It is a problem because these sites have only a single IP address public static. Did I miss something or ASA not allow connections to and from multiple subnets form a site with a unique address peer?
Resembles the limitation on the WRVS4400N as Cisco ASA supports several subnets by tunnel.
Is there anyway that you can configure a subnet more instead of specific subnets on the ACL?
For example:
If you 192.168.0.0/24 and 192.168.1.0/24, instead of having 2 subnets configured, you can combine them into 1 subnet 192.168.0.0/23

Can I have several structures with the same case of event event?
Hello
I do an application which reproduces the front of the power supply HP6675A. To do this, I did a machine to States with different States
(initialize, measures, voltage, current, ocp, ov, store, recall, etc.). In each State, should have a structure of the event that attracts the events of the buttons, as for example: If the current state is the voltage mode and the current button is pressed the next State will be the current mode. For this purpose in each State of the state machine should be the same structure of event with the same events.
My problem is that the Vi does not work properly when I have several structures with the same case of event event. There are some possibly to do and how? Or is impossible to have several events? I read a few posts, but I can't find solutions.
Any help is appreciated.
Thank you very much.
In general, you should have 1 structure of the event in your VI. In your state machine, the structure of the event should be in "pending" status So you will probably start in the State of the initialization and then spend idling. Then, the user presses the present button. If your state machine should then, go to the current state and then return to Idle.

Several files with the same name.
Cannot publish to Business Catalyst because of a fatal error, where it is said "why do we have several files with the same name? The website and all its contents have not changed in more than a year with the exception of minor changes to the wording so unable to understand what the error is encountered. Are there not better misdiagnosed at one point less for the files in question.
The problem is the result of a mixture of case-sensitive and case-insensitive between how files within the .oam are put into interaction with and what is written in the muse_manifest.xml file during a re - download full compared to an incremental download.
If all .oam packages files are tiny and the original .oam were replaced in Muse with the all new tiny .oams, then you should select Upload: publish all the files in the dialog box Options. From there, forward publication of incremental changes should work without errors.

Return of the mistake of MUSE: why do we not have several files with the same name?
Well - I thought I had all this worked and fixed, but I met the download error 'Why do we have several files with the same name' once again. (I downloaded all the files several times today in order to 1) works the way it worked the last time and 2) get an OAM file that is not loading for some reason any load again and the download takes about an hour to transfer all the files manually.
To recap:
(1) an option "Upload only modified files" returns the 'Muse has encountered an error and closes. Why do we have several files with the same name? "error just as before.
(2) a full download will work but takes forever and is NOT a substitution for work changed files option.
Please advise with possible solutions!

Is it possible to have two .oam different files in different folders on your computer where the .oam files have the same name? I'm theorizing that there may be a bug in the treatment to ensure the folder created for a .oam placed on the server receives a unique name, particularly in the case of a partial update of the site on the server.
Please send us the .muse file and all the files in .oam related to [email protected] along with a link to this topic for the context so we can attempt to reproduce this error and isolate the root cause. If files are larger than 20 MB, you'll need to use a service such as Adobe send & Track, Dropbox, creative cloud, WeTransfer, etc. file sharing. Thank you.

XOQ-01950: Cube contains several BuildSpecifications with the same name.
Hi all
When executing the option to maintain Cube he throws under question: any clue?
XOQ-01950: the AWCubeOrganization for cube 'NN_OLAP_POC. MARKET_SALES_CUBE"contains several BuildSpecifications with the same name.
Thank you
ExqThis error should show only upward when you create a cube (by importing XML), not when you maintain. So, I'll assume that's what you hear.
If you are importing XML that references an OLAP object that already exists, whereas the new definition replaces the old. The only exception to this rule is the BuildSpecification object. This kind of object is called, but it does not follow these conventions (for reasons of disorder of implementation). If you import the XML code that has a BuildSpecificaiton with the same name as one that already exists, then you will trigger the error you see. Here is a relevant example of XML.
The solution is to remove this section from the XML before importing it.

Two VPN tunnels on the same device with the same protected networks
There is a remote site that wants me to put in place two separate tunnels of VPN with the same internal IP at each end. FOR EXAMPLE
LAN = 10.212.170.201/32, 10.212.170.202/32
Remote network 192.168.0.0/24 =
I currently have a tunnel between the above:
End Point distance = 111.93.152.186
Local endpoint point = 198.205.115.252
Now, they want to set up a VPN for the same networks between:
End Point distance = 115.115.130.34
Local endpoint point = 198.205.115.252
It is my understanding that the Cisco ASA 5520 can do. The only way I've seen this done with Cisco hardware is to use two ASAs, but there may be a way to use the costs of road or some other tricks to make it happen.
I'm open to suggestions.
Is a backup?
In, specify endpoint remote second as a "backup" of the peer in the first virtual private network. Alone will be active at the time - but there are toggled if the VPN in first dies.

Download error - why don't we have several files with the same name?
Since the upgrade to 2015.1 a couple of days, I can't update my site using the feature "only changed files. If I do I get this error, followed by the Muse stops completely.
If I change the upload to 'all files and folders' everything is wonderful, even if it takes an hour to update the entire site rather than the usual 10 minutes. Given that it will only grow of it is I hope it is on the radar of the Adobe + 400 current pages team. What should I do?
Well, I got the error to stop on my own. I downloaded several times with a full scale 'all files' downloading and finally opened the site on my iMac to perform the update it. Same configuration, the same file, even software - after uploading each file one last time on the other machine I can now do a upload "only changed files" to be.

Inifile several elements with the same name
Hello
I have a file of similar to an ini file setting. I can read with the toolslib inifile.
A [SPLINE] section has a lot of variable, number, lines all begin with DATA =. The line of these data is read as a string. The content is 3 values as input for a spline interpolation.
Inifile labwindows Analyzer can read that and he can write it. The number of elements in the section [SPLINE] equals the number of rows of DATA. When he writes, he recreates [SPLINE] section with several items that all as DATA begin =.
Now I want to read later, each of these DATA items, retrieve the values of three and put them in some tables.
The ini_get('sendmail_from') functions have as input a sectionname and an itemname. So when I use Ini_GetPointerToString, I always get the first occurrence of this itemname or always the first line.
How can I get the second and third... String?
Kind regards, Jos
I'm using Labwindows CVI 8.0 for Windows
I use the inifile toolslib\toolbox Analyzer

DATA = 404.7, 27.680,-50.4; High performance Hg100 spectraal lamp * /.Hello
Thanks to you two.
Because the ini library has been able to export the complete set of data, including multiple DATA key, I had little hope that there is an easy way to use this library. Your comments, it is not useful to look for a work around.
In the meantime, I found an another iniparser (http://ndevilla.free.fr/iniparser/). It doesn't "support" no double keys, but I can probably it adapt for my application. If not, I'll take a few excerpts from the library labwindows and this second example and have to build my own.

Import multiple Word documents of several pages with the same master page?
Hi, I should start by saying that I have no experience with script. However, I wonder if there is a simple script for the following problem:
I created a master page with three linked text boxes. Right now, I use Cmd + D to select a file in word, and then Shift + click in the first box to place the text on the page. But I have 125 pages that are exactly the same, just different layout Word files to import. I could repeat this process 125 times, but I wonder if there is a way to tell InDesign to create 125 pages using the Master Page X and a for each import file?
I use InDesign CS5 v 7.0.4 on Mac OS x Snow Leopard 10.6.7 v
I thank in advance for any help you can offer,
NW
I'm sorry. The problem is that InDesign treats the two pages of the spread of master together, I guess you have to make a few hoop jump. Try this, then:
var d=app.activeDocument, p=d.pages, i, frames, masterPage, page; for (i=0; i
We have to check the whether the page is a left-hand page, and if it is, use the first page (0) of the master spread, otherwiseuse the right page.

in the examples before we talked abount 'Resolved' instead of 'resolved' as in your last example... to let you know, how it is stored.
I had advice is not to use SEPARATE.
So what... the evidence that any other question is faster than anything goes business_log, filter lines and can count distinct keys...
separate within a group function is not the same thing as do select distinct...
