Root password and /usr/lib/cron/tabs folder

/usr/lib/cron/tabs is owned by root with the permissions of "drwx------ 2 root". My user on this machine is an admin but I cannot see the contents of /usr/lib/cron/tabs and I do not know the root pw. As an admin on this machine how do I reset the root PW or get into the /usr/lib/cron/tabs folder?
Thanks.

you can use
*sudo ls /usr/lib/cron/tabs*
with your admin password.
You can reset root password by booting from the leopard install DVD and using "Reset Password" utility.

Mysql, mysql account password, and /usr/local/mysql ownership

Hi all,
I am new to osX but familiar with Linux. I have a user 'mysql' and a group 'mysql'. I would like to make mysql the root user of the database but cannot figure out how to assign a password. I see the account in netInfo and there is an encrypted password, but no way to change it.
Depending on what you read, the directory /usr/local/mysql should belong to group mysql - I don't get the concept of 'wheel' yet.
I do have a regular user named 'meandmine' [not real]. Have /usr/local/mysql/bin in my path; I can start mysql okay. When I try to execute: mysqladmin -u root password 'password' I get an error: Access denied for user 'root'@'locahost'
So where do I go. I have looked through many, many web sites including Apple, and spent several hours in Borders looking through OsX books without luck.
Guidance is appreciated.
Feel free to answer via forum or direct [email protected]
MacBook Pro Core 2 duo Mac OS X (10.4.8)

for anyone that follows this up:
I deleted the mysql install
Activated the computers root account
Installed mysql under that account a command line with su to get root access
Then followed the instructions to log in with
mysql -u root -p
[enter password]
I am up and running, and can assign access, create rights etc. to any user: in this case the only non-root user on the machine.
Thanks for the answers though , especially the bit about the UNIX forum.

Reset lost root password and now have read only filesystem

Hello,
I have recently had to reset a locked root password by booting from cdrom, mounting the first boot disk, editing the shadow file to remove root's password and rebooting the system.
The system has booted OK but, I now have a read only filesystem - everything in / cannot be edited, passwd doesnt work etc.
df -k shows the root (/) filesystem has been mounted on the physical disk I edited:
Filesystem kbytes used avail capacity Mounted on
/pci@83,4000/FJSV,ulsa@2,1/disk@0,0:a 10085836 185862 9799116 2% /
but in the vfstab it still references the disksuite metadevice:
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
/dev/md/dsk/d30 /dev/md/rdsk/d30 / ufs 1 no -
So, can I simply boot from CDROM again, amend the vfstab to be /dev/dsk/c0t0d0s0 (instead of /dev/md/dsk/d03) and reboot?
Any help with this is appreciated!
Thanks,
Emma

df -k should have shown root mounted on md0
e.g. on my machine
# df -k
Filesystem kbytes used avail capacity Mounted on
/dev/md/dsk/d0 8260691 4366317 3811768 54% /
what does /etc/system show for rootdev?
# grep rootdev /etc/system
* rootdev: Set the root device. This should be a fully
* rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a
rootdev:/pseudo/md@0:0,0,blk
Remember if this is a mirrored drive, when you boot from CD you may need to mount both sides of the mirror and make changes on both sides- otherwise the replication may not goes as expected.
Actually, I have run into problems with the modifying one side of a mirror this way. In the past Sun tech support would recommend that I break the mirror and then rebuild it once the system is up and running. So in your case you may want to boot from CD, mount the 1st disk slice, edit /etc/vfstab AND /etc/system, boot into the OS and use the various meta commands to delete and rebuild the mirror- or at least maybe to drop and reattach the 2nd 1/2 of the mirror.

Conky and /usr/lib/libcurl.so.4

Hi, while I'm new to arch I've been using linux for a good six months now and can usually get around most problems. I've basically got everything as I usually like it except for conky. I go ahead and install it, make my .conkyrc and assume I'll be good. However, when I run conky I get "conky: error while loading shared libraries: /usr/lib/libcurl.so.4: file too short". Not much else to say except what is it telling me and how do I fix it?

[stijn@lysithea ~]$ pacman -Ql curl | grep curl.so
curl /usr/lib/libcurl.so
curl /usr/lib/libcurl.so.4
curl /usr/lib/libcurl.so.4.0.1
If your box is up to date you shouldn't have any problem . Conky runs fine here.

I'm puzzled about ldd and "/usr/lib/../lib"

I'm building my own custom linux distro, and I'm puzzled about why 'ldd /usr/bin/gobject-query' shows "libffi.so.6 => /usr/lib/../lib/libffi.so.6" instead of "libffi.so.6 => /usr/lib/libffi.so.6". Archlinux is the host system for building base packages to set up chroot and rebuild them again inside. When building glib2 outside chroot I get "libffi.so.6 => /usr/lib/libffi.so.6". Building it inside chroot ldd shows "libffi.so.6 => /usr/lib/../lib/libffi.so.6". I know that it's harmless and only a cosmetic issue, but I want to know why there is two dots and how to fix this somehow.. Anyone expert on this matter?

What's in your /etc/ld.so.conf ?
Here's mine (Gentoo):

Arch:

As you can see, Gentoo's ld.so.conf is more interesting. Running "ldd /bin/bash" outputs:

Change root MSE password and password requirment

Hi All, new to the MSE world during the install of my new MSE virtual 7.0 it asks to change the root password...however the password requirement would not let me change the password and thus fell back to the default. How can I change the root password and change the password requirement.
My intial password was 15 characters long, I had 2 upper case letters, 5 lower case letters, 5 numbers, and 3 other characters
Not sure how much more I need to have the root password secure but, it was....
Any suggestions or do I just need to make the root password double what I as making it.
Thanks,
Dan

Doesn't it allow you to skip (step 17 in below) & go on to configure login & password related parameters (step 18) change those restrictions ?

Then run the setup script again & change the root password

After jumpstart host doesn't prompt for root password

Hiya gang,
I am migrating my jumpstart functionality to a new server and while it would appear that 100% of things are identical on both (as far as my /jumpstart tree is concerned), when I jumpstart a host (V240, in this case, but I've seen it on a SunBlade 150 too) everything appears to go well, but after the host reboots at the very end and I attempt to log in on console as root I am not even prompted for a password.
I've booted to single user over the net and on the disk that was just jumpstarted I see what would appear to be a normal Solaris system. There are no indications that I can find of why it wouldn't prompt for password at all, and I'm not well enough versed with the way the login functionality works to know why this is.
My new jumpstart server is running Solaris 10 (08/07), and I'm trying to jump a host with the same version. The very same jumpstart using my old jumpstart server works just fine.
Thanks in advance,
pb

Thanks for your reply. It got me in the right frame of mind for troubleshooting :)

...so, I checked them out and /etc/pam.conf and /usr/lib/security/pam_mkhomedir.so are both owned nobody:nobody, which smelled like an NFS issue since both of those files are copied over to the hosts as part of a JASS_FILES variable, but during the finish script execution (they're copied by install-templates.fin). So, I did some digging there and found another Sun forum thread that had info on it:
http://forums.sun.com/thread.jspa?forumID=841&threadID=5100999
...so I made the requisite change to /etc/default/nfs (setting the max version to 3) and the next jumpstart I tested worked perfectly, password prompt and all. All files that were previously owned nobody:nobody had the correct ownership this time around.
Crazy!
Thanks again Darren for your input!

Lost all my /usr/lib files in trial so solve glib dependency

Hi,
Failing to upgrade my Arch_X86-64 system due to glibc dependencies, I've followed an advice in the forum and tried to move (as root) all files in usr/lib to a (temporary, initially empty) directory I've created. Now I can't see any files, neither in /usr/lib nor in the backup direvtory (see terminal output below).
Please advise how to restore my system?
thanks

How do I recover /usr/lib in Solaris 10

I inadvertently deleted /usr/lib directory. Is there a way to recover this? Maybe by booting from the install DVD?
This is on a Solaris 10 11/06 SPARC install.
Thanks.

Thanks for your input.
Correct. I don't have a back up. Just built the system yesterday, but have done a lot of work since.
This is strange. I was able to mount the file system after booting from DVD. I can list the /usr/lib directory and everything looks fine. However, when I try to boot as normal I get the following errors and it locks (at least no keyboard function):
Rebooting with command: boot
Hardware Watchdog Enabled
WARNING: exec(/sbin/init) failed (file not found).
(Could not start init) Program terminated
{0} OK
ERROR:/pci@1f,700000/... Externally Initiated Reset has occurred.
ERROR:/pci@1f,700000/... Last Trap : Externally Initiated Reset
Here is the sequence of events that started this whole mess:
I tried to make a symbolic link at the root level to /usr/lib
ln -s /usr/lib /lib
Then when I did an ls -l on / the lib did not show as a link but as a regular directory.
So I tried to remove (not thinking clearly):
rm /lib
The system of course tells me it is a directory - so being the idiot that I am I did:
rm -r /lib
Then I started getting this type of error:
#ls -alt
ls: Cannot find /usr/lib/ld.so.1
Don't know for sure what I did or how to fix it.
Sorry for the long post but thought it might help solve the problem.

MYSQL Root password

Hi Guys,
I'm rather new to all this PHP and MYSQL stuff, so please bear with me. I have downloaded and installed a copy of MYSQL and PHP, and am now trying to change tohe root password, but I keep getting an error message.
I log in to MYSQL with:
/usr/local/mysql/bin/mysql
from there I type:
UPDATE mysql.user SET Password = PASSWORD('****') WHERE User = 'root';
but I keep getting an error message of:
ERROR 1142 (42000): UPDATE command denied to user ''@'localhost' for table 'user'
what have I got wrong?

I've tried to follow the above advice.
I've completely deleted my MySQl on OS X Server 10.4.7 and reinstalled using the lastest package "mysql-standard-5.0.24a-osx10.4-powerpc.dmg".
I just cannot get mysql to work properly, to set my root password.
See my first attempts with Terminal below (No.1)...
MySQL Adminsitaror and CoCoa SQL connecs with no username or password.
I've also tried to follow marcs advice at http://www.entropy.ch/software/macosx/mysql/ but to no avail.
See my second attemps with Terminal below (No.2)...
If I can crack how to reinstall and setup MySQL on OS X Server 10.4.7 then I'll have a good Disaster Recovery Plan, I hope you can help, thanks.

Trouble resetting forgotten MySQL root password

Hi there,
As the title suggests, I've forgotten my MySQL root password (and where I wrote it down) and have done endless searches (Google, MySQL site and forum, etc.), tried the resolutions but have not had any luck in resetting the password.
I tried the instructions on the MySQL site, but when I did that, I got this:
I've tried removing and restarting instances, as well as uninstalling MySQL, rebooting and then re-installing; still no success.
I'm running PHP (5.3.0) and MySQL (5.1.37) on Windows Vista.
I appreciate any help anyone can offer.
Thanks,
Heather

The simplest way that I know to deal with this situation on Windows is to uninstall MySQL. Doing so should leave the databases intact in the data folder, although you might want to copy the contents of the data folder to a different location first.
Inside the data folder is another folder called mysql. Delete it, and then reinstall MySQL. You should then be able to set up a new root password.

[Solved] Make systemctl find .service file in /usr/lib/systemd/user?

I thought this had always worked, but it seems that systemctl cannot see `.service` files that are in my `/usr/lib/systemd/user` folder and I can't figure out why:

$ systemctl status redshift-gtk
● redshift-gtk.service
Loaded: not-found (Reason: No such file or directory)
Active: inactive (dead)
I have already looked at https://wiki.archlinux.org/index.php/Systemd/User which seems to tell me to check sytemctl --user status but that appears to be loaded and working fine, I have a feeling I'm missing something obvious but can't figure out what it is. How do I make systemctl include this directory?

Lost/forgotten root password

i was given an ibook with osx but the previous owner has forgotten the root password and all attempts at a reset of the root password has failed. need to find a way to reset the root password the version of osx that is installed is oroborosxv0.75a4r2

Before buying a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.
The first thing to do after buying the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
1. If you don't own another Mac
a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
2. If you do own another Mac
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
3. Partition and install OS X
a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
c. An unusual problem may arise if all the following conditions apply:
          OS X 10.7 or later was installed by the previous owner
          The startup volume was encrypted with FileVault
          You're booted in Recovery mode (that is, not from a 10.6 installation disc)
In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.
4. Other issues
a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.

OEL 6.1 -- How to set root password?

Hi all,
Maybe it's a silly question, but I'm new to OEL, and this 6.1 install is the first time I've installed OEL.
Everything seemed to go perfectly smoothly, but the installer never prompted me to enter a root password, and now I've got a system that boots to a login prompt, but I have no idea what userid/password to use to login. Is there a default root password?
Help!
Thanks,
-Mark

Dear mbobak,
You don't need to boot into rescue image, mount, chroot
all what you need is to boot into single mode from GRUB.
If it happen again, please follow these steps:
- Reboot the system and wait for the GRUB screen to appear
- Highlight the kernel version you're currently using (usually the newest version) from the GRUB list
- Press "e" to be taken to the boot commands edit screen, highlight the line which starts with kernel and press "e" again
- Add "single" to the end of the line, so it will look like this:
kernel /vmlinuz-kernel-version ro root=LABEL=/ rhgb quiet single
- Press "Enter" to save the changes
- Press "b" to boot in single user mode.
Your system will begin loading and, at some point, you will be presented with a root bash prompt.
- In the new prompt type passwd and choose a new password for root.
- When done, type reboot to restart the system. After reboot, GRUB will be back to normal so no further modifications are required.
