When turning on Advanced Security Network Encryption tnsping fails

Hi people,
I'm installing Advanced Security Network Encryption in my server (RHEL 3), I've configured my sqlnet.ora as follows:
SQLNET.CRYPTO_CHECKSUM_SERVER = REQUIRED
SQLNET.CRYPTO_CHECKSUM_TYPES_SERVER = MD5
SQLNET.ENCRYPTION_TYPES_SERVER= (RC4_256)
SQLNET.ENCRYPTION_SERVER = REQUIRED
SQLNET.CRYPTO_SEED = "abcdefg"
After that, tnsping do not work anymore, I'm getting TNS-03505 - "Failed to resolve name".
If I remove Adv. Security configuration tnsping become normal.
Do anybody knows what can it be?
Thanks in Advance
André Teixeira

Are you running tnsping from the server to itself? Or from the client? Has Advanced Security been configured on the client?

  • Advanced Security -TDE - Encrypted Tablespace Question

    In discussions regarding the move of existing objects from a non-encrypted tablespace to a TDE tablespace, all relevant text, e.g. [TDE Best Practices|http://www.oracle.com/technology/deploy/security/database-security/pdf/twp_transparent-data-encryption_bestpractices.pdf], states that the objects should be exported from the non-encrypted tablespace and then imported into the encrypted tablespace. After which the old tablespace should be dropped, wiped, etc.
    I'm just wondering if there is a reason that we couldn't use an ALTER TABLE..MOVE operation instead. If not, specifically, why not?
    Thanks,
    -Joe

    Oracle Docs at followng link says..
    http://download-uk.oracle.com/docs/cd/E11882_01/network.112/e10746/asotrans.htm
    " You cannot encrypt an existing tablespace. However, you can import data into an encrypted tablespace using the Oracle Data Pump utility. You can also use SQL commands like CREATE TABLE...AS SELECT...or ALTER TABLE...MOVE... to move data into an encrypted tablespace. The CREATE TABLE...AS SELECT... command enables you to create a table from an existing table. The ALTER TABLE...MOVE... command enables you to move a table into the encrypted tablespace.
    So you can do Alter table move too.

  • The lock symbol does not appear when I open a secure page in firefox 4.0. Has this been removed?

    Previously, using firefox 3.6.1, when I opened a secure or encrypted page, the lock icon appeared on that page.
    When I upgraded to firefox 4.0, the lock icon is no longer appearing when I open a secure page. Please confirm whether this has been removed or in the alternative whether there is a way to determine that the secure or encrypted page is indeed secure to use.

    In Firefox 4 you no longer have the Status bar that showed the padlock in previous Firefox versions.<br />
    The padlock only shows that there is a secure connection and doesn't guarantee that you are connected to the right server.<br />
    So you might still be connected to the wrong server if you make a typo in the URL and someone has claimed that mistyped URL.<br />
    The functionality of the padlock has been replaced by the [[Site Identity Button]] on the left end of the location bar.

  • Have Effective Permissions but not showing in Advanced Security in AD UC

    I'm trying to find out where a user account is getting permissions to our Active Directory Users & Computers.  On the entire domain it has the ability to modify all properties, modify permissions, change owner, and a bunch of stuff that it
    shouldn't.  I found this out when testing and verified it with using "effective permissions".  The weird thing is, when looking at Advanced security, neither the user nor the security group it is in are explicitly given permissions anywhere
    in ADUC.  My question is:  where could it be getting these rights?  How do I find it if it's not in the Advanced Security Settings area of ADUC? 
    I know the problem is the security group and not the user account.  After I removed the user account from its security group, it no longer had the extra permissions it shouldn't have.
    TestUserA is a member of SecurityGroupA:  TestUserA has rights to all of our AD domain  (unexpected, not sure where the rights are coming from)
    TestUserA removed from SecurityGroupA:  TestUserA only has basic "read" rights to our AD domain (the desired level of permissions)
    Any help or suggestions of where to find SecurityGroupA's permissions are coming from would be helpful.  Thank you!

    Any ideas?  I would really like to know the answer to this question because there is no way for me to audit these permissions or know which other groups may be getting more permissions than expected. 
    I know for sure the user is getting permissions from SecurityGroupA.  I can clearly see using Effective Permissions that TestUserA gets added permissions in AD when I add them to this group, and the permissions get removed when no longer a member of
    this group.  It's odd to me that this group isn't explicitly listed anywhere
    in AD Security, and it isn't a member of any other groups.  Where in the world are the permissions coming from?  Viewing the Advanced Security through the mmc and running DCACLS are both useless.  The permissions are completely invisible
    to us unless we run Effective Permissions specifically against the user. 
    We are likely going to explicitly deny the group permissions since we cannot figure out how or why this group is getting permissions to AD.  This is just a quick-fix, as there still might be other security holes in our environment.

  • Airport extreme lost secure network

    I set up a secure network on my airport extreme which worked fro approx 3 weeks. I had a power cut and when power returned the secure network had disappeared. The airport is flashing yellow. I have internet access via an unsecured apple network. Where has my secure network gone?

    Welcome to the discussions!
    From your description, it sounds like the power outage may have reset some or all of your configuration settings back to factory default settings.
    Does your wireless network look something like "apple network a6h3f2", for example?
    If so, you will need to open AirPort Utility and click on Manual Setup.
    On the next page, click the word "Status" and a message will appear with information about what needs to be corrected and/or reconfigured.
    If you do need to reconfigure your settings, try to use the same device name, wireless network name, password, etc that you used before if possible.

  • Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?

    Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?
    We are not licensed for the Oracle Advanced Security Option and I have been tasked to use Oracle Network Data Encryption in order to encryption network traffic between Oracle instances that reside on remote servers. From what I have read and my prior understanding this is not possible without ASO. Can someone confirm or disprove my research, thanks.

    Hi, Srini Chavali-Oracle
    As for http://www.oracle.com/technetwork/database/options/advanced-security/advanced-security-ds-12c-1898873.pdf?ssSourceSiteId… ASO is mentioned as TDE and Redacting Sensitive Data to Display. Network encryption is excluded.
    As for Network Encryption - Oracle FAQ (of course this is not Oracle official) "Since June 2013, Net Encryption is now licensed with Oracle Enterprise Edition and doesn't require Oracle Advanced Security Option." Could you clarify this? Thanks.

  • Need a secure network when using iPad

    I have a iMac with an airport extreme card built in. I use a Westell 7500 DSL modem to connect to the internet. The modem has wireless capability. I can establish a wireless network using airport. I went into network preferences and set up WPA2 Personal security and entered a password under the network I am using, but the network is not password secured. When turning on aiport on the iPad, I join my network without having to enter a password.  I want to have to enter the password on my ipad when using this network so I am sure others in the area will have to know the password to have access to my network.
    Thank you

    According to the information you provided, you want to add a security password to secure your network.
    Your wireless network is created on your Westell 7500. So if you want to add a password to secure your network, you have to add it on the router settings, not on the iMac settings. If you're not sure how to do that, you have to contact your ISP (internet service provider) for further assistance.

  • Ibook G4 having  problem with airport connection when using secure network

    Hi,
    I am currently using a brand new Macbook. I am connected wirelessly to a Comcast network through my Netgear Wireless-N 150 router model WNR 1000. The problem I am having is with the 4 year old ibook when I go to use the airport and connect to my existing network it says the password is incorrect. I spent time troubleshooting this with Netgear and basically we found out that the ibook does connect with the network when there is no security at all.
    I erased the hard drive on this ibook to prepare it for sale and it is back to the factory settings. Is there some kind of firmware or drivers I am missing to use the airport as described?? I want to be able to show the buyer that the internet works etc. I also may want to install a few things on the ibook before the sale.
    Thanks a mil

    Did you reset the wireless router to see if by default, it has a different
    wireless security then, than however it presently is set up?
    The question you pose appears to be marked "answered or solved."
    When you reinstall an OS X, the setup asks if you have an existing
    wireless connection, or if you will be getting a new one; by default,
    the setup will make the existing one the automatic one for OS X.
    You should not have to add passwords or other, unless there has
    been one set in KeyChain or for the specific wireless base in question.
    Tiger 10.4.x does not require you to have a set password for wi-fi,
    but you will find several levels of secure options available in OS X.
    Not sure why your setup and configuration is problematic. Usually,
    a totally new OS X installation is without issue. Sometimes, you
    may have to administer a base station via Ethernet cable before
    some configurations can use it, but an existing network should be
    easy, unless it already has a password security in place.
    The Mac will work without a password-protected wi-fi internet source;
    often it will 'just work' even when moved to a new environment and
    a neighbor's network, if not password protected, will appear among
    other options in your vicinity and it will be automatically available.
    Not sure if any newer OS X update parts, from the Combo update
    files to take Tiger 10.4 to 10.4.11, plus others, would help the Mac
    connect better to whatever wireless source of internet available.
    I've not had that issue, as you state, except for when someone has
    a protected network or passwords in place. Mine has passwords to
    keep unauthorized neighbors from easy access; just in case.
    In remote locations where few neighbors exist who could access wi-fi
    from a lone source, no wireless security settings at all, work just fine.
    I've done that; and found a little greater range was gained in signals.
    And in the city (largest town in state) a computer I'd set up for use in
    a password protected wi-fi network - later worked fine and found the
    new owner's own wi-fi network without issues; and I had let the OSX
    setup assistant do its job. If a local network is protected by WEP or
    WPA2, etc with a password, one would be needed to access it. If not,
    then the connection should be automatic.
    Good luck & happy computing!

  • HT3204 I got a reading of "secure link to iTunes store failed" when I ran a diagnostic "network connectivity" test. What's wrong and how do I fix it? I am indeed unable to connect to the store.

    Can anyone help me figure out what's wrong when I try to connect to the iTunes store? I got a message "secure link to iTunes store failed" when I ran a diagnostic "network connectivity" text. What's wrong?
    Thanks for any help you can give me!

    With those symptoms, I'd try the following document:

    Try another browser. If it is not going to work, use another computer. By the way, what is the model number of your router?

  • Security Network Layer (SNC) error when creating new session

    in SAPGUI 710, suddenly some users are getting a popup message ("Security Network Layer SNC error") when they use the Create New Session toolbar button.
    SSO works fine when they connect from SAP Logon, its only when attempting to open secondary sessions.  Also, its only some users.
    Where would I find log information resulting from the error?  Or any suggestions on steps to troubleshoot?
    Thanks!

    Hello Erik,
    Issue actually belongs to BC-SEC-SNC, not SAPGUI.
    The attached note advises how to run a trace to get more information about the issue
    150104 collecting dev_trace of user session via SM04
    If you recreate the issue again with the active trace, you might have more sucess with a reply.
    Just to advise that 7.10 is out of support and 7.20 should be used as soon as possible.
    Kind Regards,

    That's not the way wifi works.
    You may see the other networks but you are not connected to them in any way.
