SSH Still Working after Hostname change???

Hi all,
I was under the impression (from past experiences) that SSH self-signed certificates are made up of the Hostname and the Domain Name of the router.
I have been working on a customer network and I can see that the SSH RSA certificate is using the old hostname of the device+domain name but SSH still works both inbound and outbound on the VTY lines!
I thought you had to zeroize the keys and recreate using the crypto key generate rsa command in order to continue to use SSH after a hostname change so that the new certificate contains the new hostname?
Any explanation would be greately appreciated
Many thanks
David

Hi David.
Yes after changing router parameter such as Hostname, domain name SSH still works with the old certificate.
What i can suggest you is to recreate it through crypto key generate rsa command in configuration mode.
HTH

  • Does GPU acceleration in Illustrator CC still work after disabling 'GPU Preview' and enabling 'CPU Preview' (on a workstation gpu)?

    I'm using a workstation graphics card that allows for GPU acceleration in Illustrator CC.
    Selecting 'GPU Preview' instead of 'CPU Preview' under the 'View' toolbar in Illustrator CC results in a more choppy experience.
    Which leads me to wonder:
    Does GPU acceleration in Illustrator CC still work after disabling 'GPU Preview' and enabling 'CPU Preview' (on a workstation gpu)?
    Does GPU acceleration for my gpu actually improve the performance for my work?

    If you disable the GPU acceleration in preferences then you'll be unable to enable GPU preview under the view menu. It will automatically go into CPU preview as the GPU is no longer enabled.
    If you're experiencing choppy performance when you do have the GPU preview selected, something is amiss because any GPU that can support GPU acceleration should be able to do it without a performance hit.
    What is the video card that's in the workstation?

  • Will all my apps still work after upgrade?

    I am always nervous doing any updates because inevitably some apps start working funny or don't work at all after them. I really want to update to Lion, but I'm concerned about some older apps I have, the number one being Final Cut Pro 7. Will this still work after the Lion upgrade? As well as all my other software?
    Thank you!

    Connect an bare external drive and install Lion onto that. Test all of your critical software to ensure it works. If you have some vitally important piece of 3rd party software that doesn't work in Lion, you may have to continue to use Snow Leopard until an update to that 3rd party software is available or you find a replacement.

  • Find my iPad - will it still work after changing icloud username/pw?

    My iPad was stolen last week.
    In haste, I quickly changed all my passwords, and even changed my Apple ID. I wasn't thinking about the fact that the iPad won't be able to connect to iCloud if I changed the password. (And of course, I can't change it back.)
    If the crooks are dumb enough to turn it on and connect it to the internet, will Find My iPad still work, even if it can't connect to iCloud?
    Thanks.

    No.

  • Ssh not working after recent security updates

    ssh worked fine just 2 weeks ago.
    in these last 2 weeks i did several updates, i am not sure which caused the problem.
    Symptoms:
    when i ssh to another machine and i get a "Segmentation Fault" error; when i scp the error message is "lost connection"
    This issue was talked about as re-occurring regularly as
    discussed on http://discussions.apple.com/message.jspa?messageID=4532389#4532389
    But the remedies or fixes suggested there did not change those errors.
    On some other site, it was suggested to use 'ssh -1 '
    which actually worked but i could not open X11 xterm window,
    which usually worked with 'ssh -X' or recently 'ssh -Y' worked instead.
    Question:
    Hopefully, the security fixes should give back the basic
    UNIX X11 functionality. The question is when ?
    (I am curious how many people are experiencing the same problems, as this seems quite a serious problem...)

  • Hotmail won't work after password change

    Recently we had to change the password to hotmail.  It was the kind where they make you wait 30 days and link to another account.  Now it says the password is incorrect when we try to update it on the iphone (4S) and iPad Air.  Rebooting does not work, nor does changing it in send and receive.  It still says the password is incorrect but it is not.  Thanks for any help.

    In case you haven't yet solved your issue, here's what worked for me.  I'm pasting below from what I just posted to try to help someone else.
    After struggling for several more hours with my issue adding my MSN mail account to my new iPhone6's iOS8, I finally figured it out!  Apparently, this applies to Hotmail as well.
    Here's the fix, in case someone else happens to need it:
    Instead of selecting Outlook.com or Other after tapping on "Add Account," select Exchange.
    Enter the username as the email address.
    Don't enter your password!  From the desktop or laptop that you normally use to access your MSN/Hotmail email, log out of your email account and then log back in, go to your account settings, click on Security, and then request a temporary password for access via apps.  That password will be a funky, long combination of random letters and/or numbers.  It will appear on your computer screen right away.
    Enter that password onto your iOS8 device.
    Voila, you're done!

  • Will iCloud mail and calendar sync still work after upgrade to iCloud drive?

    on my imac and ipad i was asked to upgrade iCloud to iCloud drive. will my iCloud mail and calendar still work on my iphone 4 with iOS 7 after i choose to upgrade?

    Yes.  iCloud Drive doesn't effect synced data such as calendars, contacts, notes, etc.  It also has nothing to do with iCloud email accounts.

  • TS3899 Email stopped working after password change

    I changed my att.net password after my account was hacked and used to send a spam email to my entire address book.  Now my iPad email will not work and I get a message that my user name or password are incorrect.  I have changed the password in my iPad mail settings to match my new password at att.net.  I have looked at the iPad support stuff on mail problems and have shut down my iPad to no avail.  I have two emails in my iPad outbox that have not been sent and I cannot receive new emails.
    ANY SUGGESTIONS.

    Howdy scad_mfa,
    Welcome to Apple Support Communities.
    It sounds like you’re running into issues sending and receiving iMessages on your notebook after changing the password for your iCloud account. The article linked below will walk you through the process of updating the Apple ID information used by Messages and other Apple services on your devices.
    What to do after you change your Apple ID email address or password - Apple Support
    Mac with OS X Mountain Lion or later
    Open the Messages app, select Messages > Preferences, then click the Accounts icon.
    If you're signed out, click Accounts and sign in with your updated Apple ID or password.
    If you're signed in with your previous Apple ID, click Accounts, then select your Apple ID from the list of accounts. Click Sign Out, then click Sign Out again when asked to confirm. Sign in with your updated Apple ID or password.
    Take care,

  • OWB repository not working after SID changed ?

    Hi,
    We have an OWB repository in a database named TEST. Recently the SID has been changed from TEST to TEST_2, and now the control center fails. Do I need to recreate the repository in the database after SID change, or could I just do some reconfigurations ? And if I could, how do I reconfigure the repository & control center based on the new SID name ?
    Thanks

    You don't need to recreate repository,
    but you should update OWB repository table ( for more details look at this thread
    Re: Unable to connect control center and start runtime service
    ) and maybe you need perform additional steps from Metalink note 434272.1 (for updating target location info).

  • Will my mac book still work after spilling coffee on it?

    I just spilt coffee on my MacBook Pro.  Will it still work if I put it in rice?

    Wow. Well umm I'm not very sure on that, especially since rice would get into your fan intakes and the rest of your internals. I would open up your MacBook Pro and use cotton swabs with 80% or above isopropyl alcohol to wibe off parts with visible coffee spill marks. Just let it dry as much as you can like this and make sure you don't get the alcohol on connectors.

  • Iphone 5 still working after 15min underwater?

    Hi folks, my ip5 got sumerged in sewer canal about 4inches deep for 15min, it was late when i found out that it fell off my pocket by accident..
    My first reaction was to check if still lights up and yes it did..  BtwI had it covered with a thin transparent plastic case with top and bottom exposed.
    So i quicly ran home and turned power off the iphone, and did the rice trick.. Im not a patient guy so i tried to power it on after 3hours and everything was working
    Fine - screen, home button, network, wifi, vibrator motor, power and volume buttons, speakers. As of now its in the rice hole and ill try it again tommorow morning
    Hopefully it works..
    Now im not sure if im lucky or is the iphone really water resistant?

    I'd leave it in the rice for maybe a week (maybe change the rice a couple of times during that, as it is not a great desiccant), or throw in some silica gel packs.  Then, knock wood, you may be lucky and it survived.  Water damage is such a variable thing that everyone's experience may be different and just subject to their luck on that day.
    If you have AppleCare+ you could also use one of your accidental damage claims to get a replacement if it does not revive fully or operates but not fully or normally.
    Otherwise, the out of warranty exchange is a pretty decent deal actually.  For the fee you get a factory refurbished unit, which is essentially like a new unit, and does have an actual factory new screen and battery.  Getting an out of warranty exchange unit will also re-instate your remaining warranty (if you have any) or 90days, whichever is longer.

  • Why won't SSH/SFTP work after the 10.6.8 update?

    I've tried just about eveything I can think of and have been googling information for awhile now but I figure I just ask the community!
    I just recently updated to 10.6.8 and now I cannot remotely log into our Linux machine running RedHat. Strange because my computer is the only one that seems to have a problem with this and it was working just fine before the update. Sometimes I'll get a "Connection Refused" error msg and other times I'll get a "Connection Timeout" error msg. I typically use the NoMachine NX client to log in, but even the ssh commands from the X11 or Mac terminal give me the same error messages. Anyone have any idea what's going on? Any help is appreciated, thanks!!

    Next step, boot in safe mode again and log in do this first:
    On the menu bar go to the "Go" option menu.
    Then go to utilities.
    Open disk utility
    Click on your Mac OS X Partition (Macintosh HD in most cases)
    Click "Verify Disk"
    If the results say "Macintosh HD appears to be OK", run it a second time just to make sure.
    If the volume structure is OK then click the "Repair Permissions" button.
    Shut down and reboot normally.
    If repairing permissions does not work, you'll have to try and install the combo update. But before we go through that run the steps I suggested above. I would suggest however to download the 10.6.8 combo update to a usb stick in case we have to reinstall it.
    Good Luck!
