Possible Crypto overlap and NAT ACL open to the vs host subnet
Hello
For a PIX 515E 6.3 (5)
I have the following ACL:
List of crypto ACL
ipsectraffic list of allowed access host ip 192.168.7.221 object-group pdvcorp-backup3-to-db1-datacenter
ipsectraffic list of allowed access host ip 192.168.7.222 object-group pdvcorp-backup3-to-db1-datacenter
permit ipsectraffic of the object-group corphosts-datacenter 192.168.10.0 ip access list 255.255.255.0
ipsectraffic permit access list ip object-group Productionhosts - data center object-group access-productionhosts-data center
In the list above Crypto ACL list, hosts, 192.168.7.221 and 192.168.7.222 are both also part of the group 'productionhosts-datacenter"referenced in the same object list ACL. What are the consequences of having the same hosts referenced in the Crypto ACL, if any?
No NAT access list
IP 192.168.7.0 allow Access-list sheep 255.255.255.0 192.168.10.0 255.255.255.0
In regards to the Crypto ACL above, is there a (security wise or another) problem with the opening of the entire subnet with an ACL sheep to save on the duty to nail each host.
Thank you
Dan
It's okay, you can use the same source to multiple destinations. No issues with the sheep.

I broke my screen, and now cannot drag to open it. I have an alarm that don't go. I can let the battery die I know but I really want to be able to access and examine what are the texts I received today. I think that my ICloud is can be disabled. I also want to synchronize my phone before I take it buy a new one. Is it possible to synchronize and watch my calendar for the next few days?
Without entering your access code, it is not possible, unless your time is in iCloud. If this is the case, connect to iCloud.com to check your calendar.
Good luck.

My 5s possible remote jailbroken and hacked so I share the same ID Apple and the person knows my passwords?

What makes you think that this could happen? If you share an Apple ID with someone and they know a lot of your passwords, they have access to a lot of your information. Change your passwords.

All,
I have nat 0 ACL indicating that an ip address should not be natted, while a static nat statement saying we need natted. I just want to know that we will have precedence.
Thank you
It is of the order of operations PIX nat / ASA.
the NAT 0 acl_name (nameif) has priority.
1 nat 0-list of access (free from nat)
2. match the existing xlates
3. match the static controls
a. static NAT with no access list
b. static PAT with no access list
4. match orders nat
a. nat [id] access-list (first match)
b. nat [id] [address] [mask] (best match)
i. If the ID is 0, create an xlate identity
II. use global pool for dynamic NAT
III. use global dynamic pool for PAT

In windows 8 screen can be divided into desktop and app half half, it would be very useful if Aurora could be opened in the application, half of the operating system and allow the normal office work to the other half, on a windows desktop 8, I can't see any advantage to use Aurora instead of Firefox, if this is not possible It's a little let down to be honest, I thought that Aurora was an excellent and practical idea.
Is there a way for this app windows 8 be opened as an app, or is it limited to the desktop?
Thank you for your help
Hello spangled101, just to clarify: aurora is a code name for the beta version of firefox hwere novelties are tested. the version that is aurora today will be available as firefox in a few months.
But back to the real question: Please refer to this article How do I bring up the aurora metro windows mode: how I run Firefox for Windows 8 Touch?

Document from Windows Media Player AND MS Windows open on the same screen
Hello.
I'm doing a very long media (recorded voice) transcript of court recorded on Windows Media Player in a document typed on MS Word (using Windows XP).
I would like to know if it is possible to have Windows Media Player and my document strikes MS Word open on the SAME screen. I am currently switch between two programs using my bottom toolbar. It is extremely time consuming and not very well. Ideally, I would like to open my Windows Media Player, in a small screen on the right upper side of my MS Word document. This would allow me to work out of the same screen without having to click will result in my bottom toolbar to switch between these programs. I'm sure that I explained properly :-). ANY help, suggestions and advice will be highly appreciated.
Kind regards
AJS
You should be able to do it by opening the two programs, then right click on the taskbar and selecting "Tile Windows vertically". Just make sure that they are only two open programs.
This screenshot shows WMP and WordPad, because I do not have Word installed, but it should work exactly the same thing:

I'm running OS X El Capitan 10.11.5 and my daughter and her friends used to watch a movie last night and stop it before releasing the film. My Mac Book Pro is the start of the password reset screen/mode? It gives me only 3 options, none of which is true. (1) I forgot my password. (2) my password does not work when you connect 3) my keyboard does not work when you type my password to connect? When I opened the Apple on lft albums he gives me a boot disc, restart and turn off? I tried all the options and it restarts just on the same page? Someone at - it advice? Thanks in advance!
The appearance of the password reset screen indicates FileVault2 is enabled on your MBP. Fix?
If so, that'll probably get you out this Pickle: https://derflounder.wordpress.com/2015/01/17/yosemites-filevault-2-pre-boot-reco very-options /

while sleeping, the computer is locked and cannot be opened by the administrator
Help. I have an old computer second, forwarded by a friend that I have more contact with. This computer is used daily by another friend who doesn't have a computer.
every night the computer go to sleep and the next day when he woke up that my bud Gets a message that it is locked and only the admin can open it.
I changed it to the administrator, but when the screen opens and he tries to enter the password, the screen seems FROZEN and don't let him enter his password.
. the only way to work around this problem seems to be to restart. as the machine is old, reboot may take 10 minutes or more. What can be done to avoid this mess?
Oddly it only happened in the last 2 weeks... for almost a year that wasn't a problem...
concise simple tips are appreciated.

I've created the new folder. When I left click it open in the search window. If I right click on it, drop-down box and select open and it opens on the window of the folder as it should. How can I get the folder to open in the right window when I left click rather than having to do the extra step by clicking on the right, and then open?
Try this link:

Is it possible to send and receive RTP streams on the same computer?
Hi all
I tried sending an RTP stream and receive it on the same computer, but it did not work. I use the AVTransmit2 and AVReceive2 classes, I assumed that these classes are popular, so I have not included the code for them) for this.
It works perfectly fine when a computer sends using AVTransmit2 and another receiver using AVReceive2. However, when, on the same computer, I get the following error in AVReceive2:
The address I used for transmission and reception is: 224.144.251.104/22200Cannot create the RTP Session: Unrecognized Windows Sockets error: 0: Cannot bind
And I also discovered that it IS possible to send and receive streams on the same computer using JMStudio, but I found it very hard to dissect its code.
How can this be achieved using these two classes, that is, the AVTransmit2 and the AVReceive2?
Any suggestions will be greatly appreciated.private String createTransmitter() { ... localAddr = new SessionAddress( InetAddress.getLocalHost(), port); destAddr = new SessionAddress( ipAddr, port);
You can do this instead:
localAddr = new SessionAddress( InetAddress.getLocalHost(), SessionAddress.ANY_PORT);

I open internet explore and is open, but when I tried to open the file such as for example the game and music they can be seen but disappear to the right of the screen, any suggestions or what to do?
I have moved your question to the windows - Forum Office topic. I suspect that your windows disappearing off the screen on a desk to externded. Check your display settings and make sure that only a single monitor/screen is shown as active.
