Network hostname change

Trouble with local hostname on same network needing to be changed

It happened to me once. I went to the sharing preferences. The computer's name had not been changed, but it could only be accessed at the new name:
I clicked "edit" and then it showed up as the new name. I changed it back to the correct name:
Then I restarted my computer (which may not be necessary). That fixed the problem and it hasn't happened since (knock on wood!).
When/If the problem becomes chronic, turning IPv6 off seems to work for some people. It a quick fix though, not a solution. By turning it off, you are also slowing down the transition from IPv4 to IPv6 as the new, more secure and faster standard protocol.
I've heard people blame routers. I have the latest version of Verizon's FiOS router and yet it happened to me too. So while you may have to upgrade your router for IPv6 to work, it will not solve this particular problem, which I believe is in OS X (Mountain Lion).  I asked if the issue had been fixed with Mavericks but I never got an answer.

  • Hostname change fantasticality?

    For example, when I am at home, and issue the command "hostname" in cmd console, it return "bogon". When I am in office, the hostname command will retuen another string.
    Anybody can tell me what's reason?
    Thanks a lots!

  • 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

  • The password for wireless network was changed.  Airport keeps trying to sign in automatically with old password and won't let me put in new password. Any ideas?

    The password for wireless network was changed.  Airport keeps trying to sign in automatically with old password and won't let me put in new password. Any ideas?

    You really should change both the wireless network name and password to avoid potential conflicts with the old and new settings.
    Suggest you give that a try.

  • Case when network is change

    Hi,
    I am creating a UDP/TCP client connection and sending/receiving data. When the network is changed (from LAN to wireless or vice versa) at my machine do I need to use any Windows API to send/receive data using active network? Do I need to do this in Windows
    or Windows API handles it itself?
    When the connection is changed, i initialize the socket, create it again & establish a new connection. But it still use old network.
    Any Suggestion?

  • Need of hostname change on existing endeca host

    Hi All,
    I have installed all endeca core packages (Mdex6.2.1, Platform6.1.1, Workbench2.1,..) and a pipeline on one of linux box. Now, there is a need of hostname change. Hope it does not break any  existing platform and pipeline. Is there any document related?
    What i can think of on endeca perspective are,
         Hostname change on environment.properties
         URL change on pipeline esp file
         Change eac central server hostname on workbench
         URL change on Preview app setting on workbench
    Is there anything else I need to consider?
    any comments are more than welcome.
    Thanks,

    Take a look at support KB: How to Change IP addresses or host names for Endeca Hosts (Doc ID 1532056.1).

  • Network setting changed...no printers, no file sharing

    I had a message "network settings changed by another application" and could not change settings. After reading the discussion forum, Jona's fix worked to resolve that. However, I still can not print anything and can not "connect to server" to share files from my laptop to my desktop (which had the original problem with settings changed). HELP! I have many projects left to print for Christmas and have no idea where to start to fix this problem. I know it has something to do with the origninal network settings issue.

    Did you delete those files or just lock the Security?

  • Terminal hostname change

    Recently the hostname changed in the terminal from hummingfish to hummingfigh-2.
    Any ideas as to the cause or the fix?
    Thanks.

    This sounds like a localnet problem. I know that the router can supply a hostname that sometimes collides or is derived from the localnet domain name.

  • UCCX Hostname Change

    Hi,
    is there a way to change the hostname of UCCX 7.0? what should be taken care of if i change the hostname?
    regards
    Prasanna

    Hi Prasana,
    Hostname change is not recommended or supported for UCCX product. Changin the server name causes SQL/MSDE database to not start up which causes major issues.
    Hope this helps

  • Hostname change with Distribution Monitor

    We will perform Upgrade&UnicodeConversion for our BI system with Distribution Monitor  parallel export/import function.
    I would like to keep hostname unchanged after export/import to avoid interface configuraiton adjustment,
    Export from HostnameS -> Parallel import to Hostname D -> Change HostnameD to HostnameS when finished (adjust SAP profile & oracle listener), does it work?
    Is there a better idea?
    Thanks,
    James

    Thanks Sunny,
    I've read this note before. I am looking for a smarter way to avoid hostname change with Distribution Monitor.
    Option 1: As I mentioned before, change the hostname back to HostnameS immediately after import in destination server.
    Option2: When import, we can set SAPINST_HOSTNAME on target server, this can be set to HostnameS, but in /etc/hosts files, the IP address of this entry is point to HostnameS, I have not figured it out......
    If there is no choice rather than changing the hostname, then we will follow this note and test all connections/configurations.
    Thanks,
    James

  • The network adapter could not establish the connection after hostname chang

    hi all,
    my computer name and ip address are changed after it is moved to another location in a local lan network. however, when i tried to connect my database in oralce 11g (enterprise edition) after, i got this error "the network adapter could not establish the connection" (in sql developer)
    and "Configuring database with database control requires a listener to be configured in the current oracle home. You need run Netca to configure a listener before you can proceed. Otherwise you may choose to continue with database control" (in dbca when i tried to create a new database). i also cannot access my database in OEM becasue it is still refering to old host name with this error message "Firefox can't establish a connection to the server at...". i changed the old host name to the new host name in files of listener.ora, listener1212114PM3012.bak, tnsnames.ora, and tnsnames1212114PM3012.bak in folder 'product\11.2.0\dbhome_2\NETWORK\ADMIN'. but it didn't work. can anybody pls tell me what do i need to do to fix the problem. i don't want to reinstall my oracle again because i've done a lot of works already in oracle. thanks in advance.

  • Can't login to Server app after hardware and hostname change

    I used Carbon Copy Cloner to completely clone a Mac mini Server onto another Mac mini Server. (The idea being that I can install and configure additional software just once and then easily set up identical servers by copying all hard drive contents.) This seemed to work great – the second Mac mini runs fine, including logins, networking etc.
    To avoid conflicts between the two servers, I changed the computer name in System Preferences/Sharing and ran:
    sudo scutil --set HostName someothername
    sudo changeip oldip newip
    The problem is that the Server app won't let me log in on the second Mac mini. It lists "This Mac" in the "Choose a Mac" dialog, but when I enter the correct username and password, login is refused (the login dialog is "shaken"). But the same login works for the operating system and SSH, and the account was definitely "allowed to administer this server". On the original Mac mini I cloned from, I can login with this account just fine.
    I even added the user account to the "Open Directory Administrators" group using ldapmodify on the command line, but that didn't help.
    Is it possible that there's something in the user directory that's bound to the hardware (maybe the Ethernet MAC address) or the hostname?
    Do you have any idea how I could fix this? I'm grateful for any help…

    this hasn't worked for me.
    When i follow the additional steps using terminal, the second command brings back the same outcome - 'David is not in the sudoers file. this incident will be reported'.
    I've been having trouble with login on for a week but didn't realise this was the problem. I've reset passwords, reinstalled OSX (twice) and now, bizarrely, i can log onto the mac mini as the administrator, but once logged in, the 'administrator' password doesnt work for anything. I can run Software Update because it comes up with a message:
    "Software Update wants to make changes. Type an administrator name and password to allow this".
    I then put in my password but it shakes and tells me its wrong.
    Can anyone advise any other solution? I'm kind of stuck - because the system doesn't recognise my admin password for updates, i cant update anything. And also because my itunes library was set up by a newwer version (I reinstalled OSX believing it would fix it reverting it back to a previous version) i can't listen to any music.
