Lost root passwd; can't log into system

I have an UltraSPARC 5 that's currently running Solaris 8. I haven't used it for years (long story) but am not trying to get it back in action. The problem is that I can't remember the passwd for root (or any other login, for that matter). I wanted to do a reinstall of either Solaris 8 or try out Solaris 9 but the system just boots straight into the existing OS load. Is there a way to force the boot sequence into the OK prompt? I'm afraid my Solaris/SPARC is very rusty these days.

Hi
1. You will need to know the root partition (/dev/sd0a or /dev/dsk/c0t0d0s0).
2. Hit the STOP-A or L1-A to halt the system.
3. Boot into single user mode, either from CDROM (boot cdrom -s) or across the network (boot net -a).
4. Mount the root partition on /a (mount /dev/dsk/c0t0d0s0 /a).
5. If you are using a Sun console, type "TERM=sun; export TERM".
6. Remove the encrypted password from the root line of one of the follwing files:
a. For SunOS 4.x - /a/etc/passwd
b. For SunOS 4.x with shadow passwords/C2 - /a/etc/passwd.adjunct
c. For solaris 2.x - /a/etc/shadow
7. Now change directories to the root (cd /)
8. Type "umount /a"
9. Now reboot into single-user mode (boot -s). The system will not have a root password. Use the passwd command to enter a new password.

    If your iPhone, iPod, iPod Touch, or iPad is lost or stolen what do you do? There are things you should have done in advance - before you lost it or it was stolen - and some things to do after the fact. Here are some suggestions:

  • I can't log into my mobile me account from my lap top.  Is it because of my operating system?  I'm on Mac OS X 10.6.8?

    I can't log into my mobile me account from my lap top.  Is it because of my operating system?  I'm on Mac OS X 10.6.8? Every time I try to enter my data in on the control panel I get an error that says; "Your MobileMe member name or password may be invalid. Please enter a different name or password."  I know the name and password is correct because I can log in via the Web.

    Apple discontinued it on June 30, 2012. Many of its services are now provided by iCloud; anything which connects specifically to MobileMe won't work.

    Hi
    https://appleid.apple.com/
    and
    https://www.icloud.com
    are two different accounts
    Therefore you should still use your "old" (existing) iCloud mail address - you cannot change the iCloud mail address.
    However you could add an alias instead to you iCloud account.

  • I can not log into iCloud

    Please help - I've upgraded to ML 10.8 (and also 10.8.1) and i can not log into icloud.
    I get an error saying "You can not log in at this time".  I have no hair left on my head because I've pulled it all out!
    Now, there are many published fixes for this, but NONE work. I've tried everything I can find:
    Yes, I have an AU and US apple ID, and both dont work
    I installed ML from a fresh disk wipe + install.  No baggage from previous OS's.
    Everything is standard, no tricky fixes or apps
    No Little snitch installed
    Have deleted the ~/Library/App Support/iCloud folder
    Have deleted any preference files
    Have opened up the permissions on the ~/Library/Caches/iCloud folder
    Have reset keychain
    Have deleted all references of any @me or @apple accounts
    Have re-installed the ML OS from a DIFFERENT bootable USB stick
    No proxies, SOCKS, or mods to network
    Plain old home WIFI network, never had a problem
    Have icloud successfully set up at work (QC 2.8GHZ Mac Pro 2010), on my iPhone, iPad and Macbook Pro - Zero issues
    The mac having problems is a 2008 iMac, Core2Duo 2.8ghz Intel w 4gb 1067mhz ram) - Runs well, use for design.
    Is it a problem with the iCloudHelper process not having sufficient permission to write to the iCloud user DB? or the Accounts folder?
    Have looked into console, and when I try and log into iCloud, I get these three errors.  Same every time, no matter which apple ID account you use:
    1: AOSKit ERROR: (System Preferences[352]) AOSKC ([email protected]): Failed to store key, couldn't add kc item, error 100013 (service=iCloud, dsid=146089737)
    2: AOSKit ERROR: (System Preferences[352]) AOSKC ([email protected]): Failed to store account info key (dsid=146089737).
    3: AOSKit ERROR: (System Preferences[352]) Failed to store account info for appleID=[email protected]
    Please help!  Is this an incompatibiloty with the iMac problem, or a ML problem? 
    Much appreciated

    Where EXACTLY are you trying to log in to it?
    Through your web browser at iCloud.com?
    Or through the iCloud system preferences pane on your Mac?

  • Can not log into server computer with any accounts - "You are unable to login to the user account "abcdefg" at this time. Logging in to the account failed because an error occurred."

    I have a Mac mini running the latest version of OS X and Server. Been running fine and flawlessly. However, I had a strange problem with the iCloud preferences panel crashing when I tried to access it, so I rebooted. Now I can not log into the system with any accounts. My master admin account (along with all the others) gives me the error:
    You are unable to login to the user account "abcdefg" at this time. Logging in to the account failed because an error occurred."
    I am able to see the server from other macs and I can log into it using the same account, but it only shows me a few of the shared folders I have access to but NOT to my main directories.
    Rebooting into Command-R and doing a disk utility, I try and repair permission on that drive and get a bunch of errors like:
    ACL found but not expected on Users
    Repaired "Users"
    ACL found but not expected on Users/.localized
    Repaired "Users/.localized"
    ACL found but not expected on Users/Shared
    Repaired "Users/shared"
    ACL found but not expected on Users/Shared/.localized
    Repaired "Users/Shared/.localized"
    Permissions repair complete.
    But rebooting is no joy...same problem. Any idea what is going on or how to repair it? Should I do a time machine restore? Complete new OS X install? Any idea what is causing this or how to salvage it?

    Got everything to re-install and it worked fine...for a few hours. Then I came in to find ALL of my network users deleted. Just GONE. Then found out the Open Directory was trashed and was unable to open, recover or restore from a backup. Looks like I may have a bad drive here.
    I installed a new drive in the system, re-installed and so far (for a couple of hours anyway) the system seems to be working and stable.

  • I changed my Apple ID password and now I can't log into iCloud

    I changed my Apple ID password and now I can't log into iCloud.  In addition I am unable to sign out or exit the iCloud System Preference page and have to force a shut down using the power off button to get rid of it.  Does anyone know how to fix this? Thanks

    If the Preference Pane hangs, hit comand-option-escape and force quit System Preferences to avoid having to reboot.
    In order to sign out you need the original password if you have set up 'Find My ....'. However you can't now change the password back to the original one (as you are not allowed to re-use a password).In this situation only Support can help you.
    To contact  iCloud Support: if you currently happen to have AppleCare, either because you recently bought Apple hardware or have paid to extend the inititial period, you can contact them here:
    http://www.apple.com/support/icloud/contact/
    You will need the serial number of the covered hardware.
    If you are not covered by AppleCare, then - in common with other free email services - there is no free support and you may be asked to pay a fee.

  • Can't log into PowerShell and EAC on Exchange 2013 Server

    I'm not sure why but I my Exchange PowerShell can't log into my Exchange server and I can't access the EAC
    via localhost or the URL. 
    I did notice that I enabled HTTP Proxy in IIS and that I used Application Route Requesting with it but I went ahead
    and reversed all those changes. I also noticed that the physical path for each sub-site in Default Web Site goes to the HTTP Proxy version of that folder instead of the ClientAccess one. I changed each folder to the clientaccess one but that didn't help. I
    did some research on this and I saw that I had to enable the kerbauth in the modules area and I did that to. I restarted IIS and WebRM and that still didn't help.

    Where are you trying to log in? You should be able to change your ID at http://appleid.apple.com - can you log in there?
    Before you change your ID you should log out of the iTunes Store and on any devices which are logged into iCloud. Then once you've changed it you can log back in with the new ID. (Your iCloud synced data will disappear from the device when you do this but will reappear when you sign back in - give it time).
    If you are unable to sign into http://appleid.apple.com you will need to contact Support. Go to http://iforgot.apple.com and sign in with your iCloud login. A new password will be sent to your associated email address. If this doesn't work you will have to contact Support. Go to https://getsupport.apple.com . Click' See all products and services', then 'More Products and Services, then 'Apple ID', then 'Other Apple ID Topics' then 'Lost or forgotten Apple ID password'.

  • New users can't log into /mydevices or /profilemanager

    Hi all,
    I've got Profile Manager up and running and have deployed about 25 iPads using the current setup.
    My configuration has not changed but all of sudden, new users created today can not log into /mydevices or /profilemanager.  Says the username or password is incorrect, but they're entered properly.  Again, the configuration of the server has NOT changed since users entered (and working) last week.
    Anyone have this issue?  If anyone can shed some light, I'd really appreciate it.
    Apple: Lion Server is buggy as ****.  Profile Manager is buggy as ****.  I've spent hours on the phone with Apple support with one issue after another.  I'm getting sick of the instability and crankiness of Lion Server.  These forums are chalked full of people having such a massive range of issues that I can only draw one conculsion: Lion Server is half baked.
    Please help (again),
    Chris

    I got my problem solved - and here is a few things to note and some steps to resolve the issue.
    1) you do not need to create augmented users - unless you need extra settings for local logins (you most likely won't have users logging into your mav) - if you are using AD that is - if not just create local users
    2) server is buggy - perhaps - but after dealing with this issue for a few days - as much as i want to agree with it i want to say that now it is running very smoothly - and it boils down to order of steps in the install
    4) do not change hostnames once it's set up - that will scre it up even worse
    here is what i woudl suggest to blow it away and reset it up
    1) system pref - users and groups - login options - network account server - edit - unjoin the domain
    2) blow away your open directory and profile manager in command line
    sudo /usr/share/devicemgr/backend/wipeDB.sh
    sudo slapconfig -destroyldapserver
    3) reset apache web config
    sudo /serveradmin command web:command=restoreFactorySettings
    4)make sure your hostname is correct
    5) join domain (if needed)
         on command line veryfiy ad is working by typing
         user "username" where username is username of AD user
    6) if AD set up - check dns search order - make sure no local host (127.0.0.1) is in the list
         system preferences - network - ethernet - advanced -dns - remove 127.0.0.1 if there (only if using AD)
    6) server admin - open directory - settings - change - set up as standalone
    configure yoru ldap server - this will reissue signing authority certificate that you will need if you want to sign your configurations profiles for clients (iOS and Mac)
    7) then configure profile manager
    Reboot after step 2 - step 3, step 6
    if you have a firewall infront of the server there will be aditinal ports required for SCEP
    http://support.apple.com/kb/TS1629
    you will need port 80,443 and 1640
    If you have a reverse proxy you will need to set up a trust to the cetificate on the proxy to the authority configured in the open ldap - different topic - but just tought it was worth mentioning

  • EPM 11.1 Install Problems - Apps not in SS/Can't Log into Wkspce/Install ?

    Hi all...
    Was attempting to do an install w/ separate tablespaces in Oracle. Read install doc and saw this note
    "To use a different database for each product, perform the “Configure Database” task separately for each product.
    In some cases you might want to configure separate databases for products."
    Guess I may have read it wrong but basically, tried running config for an entire app one at a time vs. just running the config database and then performing the remainder of the confg tasks for all apps. Validates okay (except Studio -- connection string doesn't seem to be working although looks okay in the .properties file -- but can fix that later), however now I have the following problems:
    Planning, Reporting and Analysis apps are not showing up in Shared Services nor are there any roles associated with these apps so I can't provision a user for access.
    Can't log into Workspace to see if my apps are are there -- tried using "admin" "password" but get error message "You must supply a valid user name and password to log onto the system". Which makes sense -- there are no roles for these apps and, therefore no users w/ access to these...
    So, first question -- When Oracle says to run the Configure Database task separately for each product, does that mean I was supposed to select only this specific task for each product and then run the config for all products w/ the "configure database" deselected?
    Next question -- Any way to force the app to register to Shared Services? The apps that are not showing in Shared Services do not have any apparent tasks for doing this and some only have a choice between configure database and deploy application server -- don't really want to chose either of these as would think it would get really, really messy (that is, would it deploy a second app server or update the current one?)
    Trying to avoid uninstalling but that may be the only option. However, before I do that wanted to make sure I understood the Oracle note about "Configure Database" (see question above).
    Any thoughts welcome.
    KJ

    So, John...
    Good info on the the EPM Workspace issue. After installing the R&A Migration package, BI Plus and roles were available in Shared Services and I was able to log into Worksapce with both my previously non-working Admin/password account and a test user account. And, as an added bonus, the previous Oracle connection string error I was having w/ Essbase Studio disappeared!
    Unfortunately, Planning and EPMA did not get a boost from that fix so, am currently in the process of uninstalling, which as you noted was not all the clean at all -- actually didn't see any difference after the uninstall from the install, and installing.
    Install appears to be laying down the files (manually deleted the Hyperion directory...) okay. Will have to see how it goes from here. Think I will try the route of doing all the configure database tasks for all the apps first (to keep them in separate tablespaces and instances) and then doing the config for all the apps at one time.
    BTW... Is there a "published" configuration sequence? I read the "Start here" and Install doc from cover to cover before starting the install and config and did not see any specific notes on the order of configuration... Just curious as I have seen several notes that allude to this being in the install doc. Am I just totally missing something?
