• IOS ACL interaction w / inspect CBAC

  Sorry to bother you guys, but I'm banging my head against the wall with this one

  [Vs ACL CBAC Ip inspect]

  Specifically, SDM created the following configuration:

  inspect the IP name SDM_LOW cuseeme

  inspect the IP dns SDM_LOW name

  inspect the IP name SDM_LOW ftp

  inspect the IP h323 SDM_LOW name

  inspect the IP name SDM_LOW https

  inspect the IP icmp SDM_LOW name

  inspect the IP name SDM_LOW imap

  inspect the IP name SDM_LOW pop3

  inspect the IP name SDM_LOW netshow

  inspect the IP rcmd SDM_LOW name

  inspect the IP name SDM_LOW realaudio

  inspect the name SDM_LOW rtsp IP

  inspect the IP name SDM_LOW esmtp

  inspect the IP name SDM_LOW sqlnet

  inspect the name SDM_LOW streamworks IP

  inspect the name SDM_LOW tftp IP

  inspect the tcp IP SDM_LOW name

  inspect the IP udp SDM_LOW name

  inspect the name SDM_LOW vdolive IP

  !

  !

  interface FastEthernet4

  IP 100.100.100.1 255.255.255.0

  IP access-group 101 in

  inspect the SDM_LOW over IP

  access-list 101 deny ip 10.10.10.0 0.0.0.255 any

  access-list 101 permit icmp any host 100.100.100.1 - response

  access-list 101 permit icmp any host 100.100.100.1 time limit

  access-list 101 permit icmp any unreachable host 100.100.100.1

  access-list 101 deny ip 10.0.0.0 0.255.255.255 everything

  access-list 101 deny ip 172.16.0.0 0.15.255.255 all

  access-list 101 deny ip 192.168.0.0 0.0.255.255 everything

  access-list 101 deny ip 127.0.0.0 0.255.255.255 everything

  access-list 101 deny ip 255.255.255.255 host everything

  access-list 101 deny host ip 0.0.0.0 everything

  access-list 101 deny ip any any newspaper

  So as you can see, the DENY ANY ANY of the ACL would block return traffic wouldn't it? I thought that the ACL is applied FIRST? So I guess that by looking at this config when CBAC examines traffic OUT on the external interface, it can - then - create holes in the ACL to allow return traffic. Is this correct?

  And if so, why not simply allow the implicit DENY ALL; does deny ip any all appear explicitly in the ACL?

  I read through the guide 12-4 of the site of Cisco security configuration and do not answer this question.

  Thanks in advance

  :-(

  Your assumption is quite right, THAT CBAC is open a hole in the ACL to allow the return of return traffic.

  Regarding the ip to refuse a whole at the end of the access list, it's a line of best practice added to the access list, if you look at the line, you will notice that there is a keyword of log at the end of the line, so this is to log traffic refused a syslog server for example for you to review traffic later and analyze only in case you get attacked or sth like that.

  You can remove this line if you think it's unnecessary, but as I said to you that it is a good practice when it comes to the access lists.

• Mr President, for my iPad 2, that I am currently on version 5.1. I want to update manually in order for ios ios 6 then 7; Please help on how todo it

  Dear Sir, I am currently on version 5.1 and want to update to the current version of iOS in the sequence. I need to update to iOS 6 then to iOS 7 followed by upgrading to the current version. I tried to do the upgrade manually, but I don't see anyway to do it manually using iTunes. Could you detail the steps for manual update process. There are several sites where there are older versions, but how to address those who use iTunes. Help, please.

  You can not. An iPad 2 can only be updated directly to 9.2.1 or the beta version of iOS 9.3; If an intermediate version of iOS is somehow installed force on this issue, it will not be activated.

• Inspect the SMTP

  In deb ip inspect smtp I get the following message:

  The CBAC SMTP: replacement EHLO by NOOP

  I guess it's because my client has an Exchange Server and the EHLO is an extended Smtp command my firewall Don t know. It s correct?, and I can solve?

  My firewall is a Cisco3640 with IP/FW/IDS 12.2.8T5.

  Thank you

  Yes, SMTP mail Guard allows only the 7 commands defined in RFC 821 4.51 section:

  Data

  HELO

  Mail

  NOOP

  Quit smoking

  RSet

  For email servers, like MS Exchange, which are not entirely conform to the rfc 821, the PIX generates a 'noop' for other than listed above 7 orders. That's why you see "SMTP CBAC: changing EHLO to NOOP ' there is currently not a way to add/delete orders from those listed above. If you must have this turned off, use the correction no protocol smtp 25 - this is not recommended because it will disable mail Guard.

  I hope this helps.

• My router supports CBAC?

  It seems that some router IOS versions 12.2 or better to support CBAC and others do not. Is there something that I can look in the NVA SH or SH RUN where I can tell if the operating system supports the IOS Firewall Feature Set?

  OK, let's try again. I know it can be confusing. In 12.1 images and earlier versions (I think), you can identify an IOS image that has the CBAC (or IOS Firewall because it sometimes referred to as) features enabled by finding an 'o' in the name of the image file. Beginning in paragraph 12.2 and later versions, you can identify it with a 'o3' in the name of the image file. They both mean the same thing. The image I posted wasn't c1600-osy56i-l. 121 - 11.bin. Note the "o" in the name of the image after the flag of the platform.

  Now, to the FW part. In the center of software for different IOS images, you will see various lengthy game descriptions. The active CBAC feature sets will have FW in the description. For example, http://www.cisco.com/cgi-bin/Software/Iosplanner/Planner-tool/iosplanner.cgi?get_crypto=&data_from=&hardware_name=1601-1604&software_name=&release_name=12.2.19a&majorRel=12.2&state=:HW:RL & type = limited % 20Deployment you can see the following: IP/FW MORE IPSEC 56

  Note the above FW. This indicates that this link will take you to an image which has features of firewall enabled and has also a 'o' or 'o3' in the name of the image file.

  Do not confuse the version "bootstrap" in the code with the version of the code that is running on the router. You can go back and review the output. This should be the code of 12.1 (11) for a 1600.

  CBAC has been added to IOS in 12.0 (5) T and later in 12.1 mainline as well. All versions should subsequently have active CBAC IF a 'o' or 'o3' exists in the name of the image file.

  I really hope this helps.

• Old iOS that app is improved with a new generation of Air is not verified by the Apple Store because of the limitations of UIRequiredDeviceCapabilities in the info.plist file

  We ordered to upgrade an old iOS/Android app.

  We have developed the new app with Flash Professional CC (Build 15.0.1.179) + Adobe Air (19.0.0.190) for the two operating systems. No problem on Android. Apart from a bit of work by removing the prefix app id air.

  Also construction parts new and several dimmer on iOS was perfectly conducted.

  The issue raised during the passage of the generation of production to the audit. The error returned is

  The APP's info.plist can contain the value of the UIRequiredDeviceCapabilities key that would prevent this app to open on any iOS device.

  After a lot of searching on Google without solutions, we realized that the problem is that the old version of the app has no restrictions of use, while the new! In fact AIR compiler automatically inserts this pair of values in the info.plist file

  
  

  < key > UIRequiredDeviceCapabilities < / key >

  < table >

  < string > armv7 < / string >

  < string > opengles-2 < / string >

  < / array >

  which means the new app cares something and will not let the devices to run itself!

  This two capabilities of our reviews are almost useless as soon as iOS version 7 + (according to the guidelines of our generation) does not require the

  < key > MinimumOSVersion < / key >

  < string > 7.0 < / string >

  in any case it is

  How to remove this key in the info.plist file?

  It is our opinion that Adobe needs to find a solution in the compilation process, because if these required features are mandatory, it is virtually impossible to migrate from almost any old application to the air framework, which seems nonsense.

  Hope someone can help us.

  Thank you

  I finally found a solution for this problem and want to share it here to help all developers have the same problem.

  I have downloaded an application for Mac, called AirSign (https://www.airsignapp.com/), which allows to edit and re-sign .ipa assuming you have good certificates and provisioning profile.

  By using this application, I have delete the unwanted required functions (opengles-2 and armv7) then export to Xcode Archive.

  Then I opened archive with XCode and packed the new .ipa from there.

  Finally, I downloaded the App loaderipa.

  Note that AirSign can repack the ipa, but for some reason, I don't know it is not accepted when downloading with the Application Loader.

  I really hope this can help, and I'm guessing why Adobe is not interested in this problem.

  Ciao

• The last backup could not be completed

  I tried for a few months now to save my device (iPhone 5) to iCloud without success. I tried all the different 'solutions' I found that worked for others, but none of them have made successful with me. I will list below all of the actions that I took to try to solve this problem.

  I would say that the iphone was always running the latest iOS, so this should not be the issue.

  1 soft reset (holding the lock and the "home" button)

  2 remove the old backups iCloud

  3. disconnect my account iCloud and back in the signature.

  4 make a network settings reset on the device.

  5. try to backup to another network (wi - fi)

  6 purchase of extra space, thinking that even though I had enough space to perform the backup, this could finally solve my problem (he didn't).

  Please note that all my other devices fine backup, it's just this one this backup won´t no matter what I do. And every time I try to save the equipment it just freezes on this screen, never not the real up, nor did the blue bar shows any advance.

• Skype 7.27.80.101 is arch entering video 4:3 with black bars of spruce in the 16:9 monitor

  We use Skype every day and since August, we have noticed that some video entering various contacts appears in 4:3 with black bars on the sides to adapt to our 16:9 screen. The guest who call in all have various devices, we checked, it be PC, Mac mobile laptops, Android and IOS devices. Test, we had the issue with our version of Skype.

  We have 4 identical version Skype windows 7 PC, a PC does not have the problem and the only difference is that he is running Version 7.24, 3 other PC with Skype worm 7.24 all have the problem.

  We think back of role, but it would be good to be able to stay up to date.

  I don't know if there is nothing special in the version 7.27. I have observed this behavior on several versions previous too, but Skype is changing often ('improvement') the bargaining procedure for the 'best connection possible', so anything is possible.

  In all cases, the difference can also be in the applied codec (NGC versus silk), and as far as I know, there is no known way to force the selected codec. It's one thing entirely controlled by Skype.

• Why is-internet and network server

  When online on my Macbook Air, I often find internet connection dropped and research in Network preferences / help / diagnosis, I find server and Internet keys shown yellow status. I can almost always reconnect easily by clicking on continue and re - select the wireless network (a 5 Ghz one, but the same problem exists with my network no 5 Ghz), then I click on option to allow Network Diagnostics key to the network selected in my keychain.

  This often works very well in a few seconds, so not a big deal but sometimes very annoying because it can occur several times in a short period or during a day, and then not at all for hours or days, but often it's almost every day.

  Here is a list of equipment etc:

  MacBook Air 10.10.5, Imac 10.10.5, VirginMedia superhub, Airport Extreme (in bridged mode), Airport Express (closer), Apple TV (often disabled) iPhone 6s.

  Problem is really only apparent on Macbook Air, iMac has (if Wifi also in operation usually) ethernet connection. iPhone6 seems to have no problem with wifi internet at home or elsewhere.

  I quite often other problems in my Wifi system, however, recently, especially when you use Apple TV, Airport Extreme and Express and modem even falling Airport utility, which I always managed to correct later in various restarts and resets. But the preceding is the most frequent being almost a daily reality at least once or twice.

  I tried to choose different channels in Airport utility for Airport Extreme and Express networks, but this made the incredibly slow connection (normally it is 36 Mbps on Macbook). I also disabled IPv6 on all devices (or put the link-local), and this seemed to help with the problem of the Apple TV appears to have had no effect on this.

  I also disabled Bluetooth on Macbook while writing this, but the problem has happened several times already.

  This happened to my wife (for me) for awhile now.  I had not thought to check this forum until now. We have Airport Extreme in Bridge connected to Comcast cable modem mode (not sure of the brand/model right now) and the connection features include retina Macbook Pro, Macbook Air, iPhone 2 6, iPad, iPad 2 Air Air, not to mention a number of non-Apple devices.  It is the problem most often on MacBookAir and iPad Air.  Turns off WiFi for a few seconds, then turn it back on again and then it works OK.  This seems to occur several times a day and could happen just after awakening from a sleeping device.

  All devices are up to the latest version of iOS and Mac OS x

  Another issue that could be related have to do with the Airport Express in "Client" mode  Set up to provide wired ethernet port for a device far the main router.  Note that in this mode, it is not (supposed to be) providing a wifi signal, just in its port ethernet access.  It seems to work, but quite often, maybe once a day, he kills wifi in its immediate vicinity.  If I'm in the room with him and lose the wifi then go to a location close to the main router I'm back online again.

  I would like ideas or cures that anyone might have on any of these problems.

• Audio does not not on iPhone

  I create a responsive project on Captivate 9.0.2.421. I downloaded the xAPI file to my LMS and tested in my iPhone6s (iOS10). The sound does not work. All other works, but I can't hear anything.

  To see if it was a problem with the file type (xAPI), I went to a class I created about a year in Captivate, what is a SCORM file. This file SCORM course previously worked, but now the audio does not work.

  Thoughts? Thank you for your community support!

  It is now a known issue with the release of HTML5 on IOS 10.

  Please log the issue with Adobe.
