Sudo doesn't work anymore, not permitting me to enter password
Since two days, sudo doesn't work for me anymore. When I do
sudo any_command
I get:
Sorry, try again.
Sorry, try again.
Sorry, try again.
sudo: 3 incorrect password attempts
I updated my server two days ago, but I cannot say whether it's related to my problem.
Here's the result of doing
tail /var/log/sudolog
as root (su works):
Oct 13 12:35:33 : kalasusi : 3 incorrect password attempts ; TTY=pts/2 ; PWD=/etc; USER=root ; COMMAND=/bin/ls
Here's the result of doing
tail /var/log/auth.log
as root (the last new lines after trying sudo again with my normal user):
Oct 13 14:52:59 myserver sudo: pam_unix(sudo:auth): authentication failure; logname=kalasusi uid=0 euid=0 tty=/dev/pts/1 ruser=kalasusi rhost= user=kalasusi
Oct 13 14:53:05 myserver sudo: kalasusi : 3 incorrect password attempts ; TTY=pts/1 ; PWD=/home/kalasusi ; USER=root ; COMMAND=/bin/ls
For some background info, the sudo troubleshooting guide identifies such a problem (the third Q&A):
Q) Sudo never gives me a chance to enter a password using PAM, it just
says 'Sorry, try again.' three times and exits.
A) You didn't setup PAM to work with sudo. On Redhat Linux or Fedora
Core this generally means installing sample.pam as /etc/pam.d/sudo.
See the sample.pam file for hints on what to use for other Linux
systems.
The only problem is that I didn't change anything from the Arch stock configuration of /etc/pam.d/sudo, and it used to work. Here's the result of
cat /etc/pam.d/sudo
on my system:
#%PAM-1.0
auth required pam_unix.so
auth required pam_nologin.so
Something else that comes into my mind that might be connected with the problem is that at some point while doing maintenance on the server, I received the following error:
Authentication token manipulation error.
Unfortunately I don't remember in what context it was or whether the problem started afterwards. I believe though the problem is either that or the update, because those are the two extraordinary things that happened on the server since the problem started.
Anyone have any ideas? Thanks in advance!

Su doesn't work anymore but sudo works
Hi all,
I normally use my standard user account but when I'm installing with macports I routinely "su" into root to do things.
Today I went on my machine and noticed that "su" wouldn't work. Before anyone decides to tell me that I don't need to use "su", I realize that but I use it for my own purposes.
From the system log I am seeing this each time "su" fails:
su[1376]: pam_authenticate: Permission denied
What is interesting is that doing a "sudo su" works, and I'm able to do all of my admin duties that way.
I have a feeling something messed up my bash profile but not totally sure. Has anyone else run into this issue?Hi all,
Thanks for the help on this issue.
I'll clarify: I'm using this install as a server and this is why I have 2 admin accounts on it. The original account is my own; the one I created when I first installed OS X. I then enabled System Admin (root) so that is the other admin account. After installing MacPorts I have been running the system as a multi-user webserver. I occasionally log in as root to do maintenance and upgrades. I have found that it's easier to use the SysAdmin account in certain situations because of permissions issues and ease of installing upgrades.
I'll often log in under my username and then su to root. Recently (yesterday) I noticed that "su" didn't work anymore when I used my normal username.
There are sometimes that I will log onto the machine as System Admin and usually via the terminal (console) I can log in as any of the other accounts by doing
su <username>
this also doesn't work anymore. I get the error:
shell-init: error retrieving current directory: getcwd: cannot access parent directories: Permission denied
I have two servers set up this way. One works the way it should, the other one has this problem. The only difference I can see is in roots bash profile but I'm not sure why they are different on each machine.
Also when logged in as System Admin, I should be able to turn off "allow user to administer computer" on my regular account but it's grayed out. On the other similarly configured machine, under the same conditions, I can. I'm not sure why I can do it on one and not the other.
I've tried turning off enable root via Directory Utility but that didn't fix the issue. -

I can't seem to get my iMac (late 2009 model) into automatic sleep mode. If I manually put it into sleep I don't have any issues.
I used to solve the issue by running "PleaseSleep" application but that doesn't work anymore since Lion. I now want to fix the underlying problem.
I'm not running any weird background processes and in my energy saver settings I've tagged "put the hard disk to sleep when possible:, "allow power button to put computer to sleep" and "automatically reduce brigthness". All pretty standard.
Is there anyone who can give me some pointers ?Today I solved the same problem for my iMac running Snow Leopard. See https://discussions.apple.com/thread/3008791#15947706. The method may help you, too.
For me it was the DynDNS Updater preventing my iMac from automatically entering sleep mode.
To my knowledge the cause of this sleep problem can only be a peripheral device or a process. So I suggest to first unplug all peripherals and test whether that's the cause. If not, I suggest to terminate one process after another and to test automatic entering of sleep mode after each. Start with user processes; continue with system process if necessary.
At least that's the way I found the offending process. Fortunately, I was able to change the configuration of that process to allow again automatic entering of sleep mode.
Good luck! -
Time Machine Just Doesn't Work Anymore
I was a happy Time Machine (with Time Capsule) user for months. But it just doesn't work anymore. It takes longer than an hour to do every hourly backup so it is backing up 24 hours a day. It finds hundreds of thousands of files changed every hour and tries to back them up. Finders says only tens of files have been modified all of today. I have tried rebuilding my spotlight indexes, repairing my Time Capsule with Disk Utility and starting over with a brand new backup. But it just backs up hundreds of thousands of files every hour. So I am turning off Time capsule since it is clearly broken. If anyone has any suggestions at all I would welcome them.
Marcia,
Consider the following, it might give you some ideas:
Time Machine performs backups at the file level. If a single bit in a large file is changed, the WHOLE file is backed up again. This is a problem for programs that save data to monolithic virtual disk files that are modified frequently. These include Parallels, VMware Fusion, Aperture vaults, or the databases that Entourage and Thunderbird create. These should be excluded from backup using the Time Machine Preference Exclusion list. You will, however, need to backup these files manually to another external disk.
One poster observed regarding Photoshop: “If you find yourself working with large files, you may discover that TM is suddenly backing up your scratch disk's temp files. This is useless, find out how to exclude these (I'm not actually sure here). Alternatively, turn off TM whilst you work in Photoshop.” (http://discussions.apple.com/thread.jspa?threadID=1209412)
If you do a lot of movie editing, unless these files are excluded, expect Time Machine to treat revised versions of a single movie as entirely new files.
If you frequently download software or video files that you only expect to keep for a short time, consider excluding the folder these are stored in from Time Machine backups.
If you have recently created a new disk image or burned a DVD, Time Machine will target these files for backup unless they are deleted or excluded from backup.
Installing new software, upgrading existing software, or updating Mac OS X system software can created major changes in the structure of your directories. Time Machine will backup every file that has changed since the installation.
Files or folders that are simply moved or renamed are counted as NEW files or folders. If you rename any file or folder, Time Machine will back up the ENTIRE file or folder again no matter how big or small it is.
George Schreyer describes this behavior: “If you should want to do some massive rearrangement of your disk, Time Machine will interpret the rearranged files as new files and back them up again in their new locations. Just renaming a folder will cause this to happen. This is OK if you've got lots of room on your backup disk. Eventually, Time Machine will thin those backups and the space consumed will be recovered. However, if you really want recover the space in the backup volume immediately, you can. To do this, bring a Finder window to the front and then click the Time Machine icon on the dock. This will activate the Time Machine user interface. Navigate back in time to where the old stuff exists and select it. Then pull down the "action" menu (the gear thing) and select "delete all backups" and the older stuff vanishes.” (http://www.girr.org/mac_stuff/backups.html)
*TechTool Pro Directory Protection*
This disk utility feature creates backup copies of your system directories. Obviously these directories are changing all the time. So, depending on how it is configured, these backup files will be changing as well which is interpreted by Time Machine as new data to backup. Excluding the folder these backups are stored in will eliminate this effect.
*Backups WAY Too Large*
If an initial full backup or subsequent incremental backup is tens or hundreds of Gigs larger than expected, check to see that all unwanted external hard disks are still excluded from Time Machine backups.
This includes the Time Machine backup drive ITSELF. Normally, Time Machine is set to exclude itself by default. But on rare occasions it can forget. When your backup begins, Time Machine mounts the backup on your desktop. (For Time Capsule users it appears as a white drive icon labeled something like “Backup of (your computer)”.) If, while it is mounted, it does not show up in the Time Machine Prefs “Do not back up” list, then Time Machine will attempt to back ITSELF up. If it is not listed while the drive is mounted, then you need to add it to the list.
*FileVault / Boot Camp / iDisk Syncing*
Note: Leopard has changed the way it deals with FileVault disk images, so it is not necessary to exclude your Home folder if you have FileVault activated. Additionally, Time Machine ignores Boot Camp partitions as the manner in which they are formatted is incompatible. Finally, if you have your iDisk Synced to your desktop, it is not necessary to exclude the disk image file it creates as that has been changed to a sparsebundle as well in Leopard.
Let us know if any of this helps.
Cheers! -

As hwd doesn't work anymore... [SOLVED]
As hwd doesn't work anymore, I have a problem with installing and maintaining Xorg on my Arch machine. I recently reinstalled Archlinux on my desktop machine, and was unaware that Xorg had been updated.
So when I tried to do my normal installation routine of installing all the necessary drivers, xorg and hwd, I ran into a problem. When I ran hwd -u + -xa, it said No X server installed. I searched around and found out that hwd was not supported any longer.
So I figured i'd just do the manual configuration of Xorg. So I ran X -configure, and then ran the server. Everytime I did this, the computer would freeze up upon entering the environment.
So I tried doing nvidia-xconfig, and ended up actually getting into the environment, but after all the xterm windows had popped up, it froze again everytime.
After reading abit articles on the subject, I tried letting Xorg simply use HAL for it's hardware recognization. This time it worked, and I was able to enter the environment with no problem. So I went with this alternative, and installed Openbox.
Now, the problem shows up when I enter the environment. I can clearly see that there's somewhat of a problem with the graphics. So I tried configuring a minimal xorg.conf to run along side HAL. This still didn't fix the problem. The problem is, there are areas of the screen that are SLIGHTLY blurry. For example, if I write something in xterm, then move it to certain parts of the screen, the text becomes mildly blurry. It's not a big problem, just irritating. But this little problem may be an indication of a bigger problem. I'm sensing I don't have 3D capabilities, but haven't tested yet.
Another thing is; When I write something in xterm while in the environment, and I hold down the backspace button... Xorg simply crashes without any particular error.
Anyway, my point is; I had an idea that, is there some way to make hwd recognize the xorg server as a older version, making it configure a file for it? I've never had any problem with xorg up until this new update, which irritates me alot, making me want to find some other distrobution of linux.
I hope someone can help me fix this.
Last edited by SomeoneWithAPurpose (2009-05-15 22:24:17)you could roll back your Xorg version to continue using hwd in the meantime...
I'm assuming you've followed http://wiki.archlinux.org/index.php/Xor … _xorg.conf to try without xorg / with minimal xorg. Have you ensured that your drivers are up to date? I would attempt reinstalling video drivers, trying HAL again with NO xorg file, and if that fails, try it with minimal xorg.
Hopefully someone comes along with a more concrete solution...I'm just hoping to steer you down a path of some new ideas (if you havent already tried this...)
I had some trouble with the latest version. Reinstalling video drivers and running with no xorg.conf was the fix...I know you said you tried this same thing, but you havent specified how new your drivers are or anything... Good luck and free bump! -
IMac freezes & Time Machine doesn't work anymore
Hello,
For several days now my trusty iMac (two years old) keeps freezing without a recognizable pattern. Programs like iTunes, iPhoto or maybe even the Finder just stop working and display only the rotating ball - the only thing left to do for me after that is to manually terminate that process or (in the case of the Finder) to restart the whole iMac. I'm really clueless as to where this behaviour suddenly comes from, up until about a week ago the iMac worked perfectly. And now something like this happens every single time I start it.
Another thing that doesn't work anymore is Time Machine. My last automatic backup is from September 17th. After that it just stopped working. Every time an automatic or manual backup is initiated it just says "Searching for backup volume" but doesn't find it, even after several hours of looking. The Time Capsule itself works perfectly, no errors whatsoever.
My iMac is up-to-date, I also already ran the disgnostics of the hard drive program - everything seems to be fine. Can anyone help me?

Mapping paths to servlets doesn't work anymore in SP5 ??
Hello,
see subject.
I have a small web application which is contained in a WAR-file named
"httpdump.war". Its deployment descriptor (web.xml) maps the servlet
httpdump.HttpDumpServlet to the path /servletpath/* with the following
XML statements:
<servlet>
<servlet-name>HttpDumpServlet</servlet-name>
<display-name>The HTTP Dump Servlet</display-name>
<servlet-class>httpdump.HttpDumpServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HttpDumpServlet</servlet-name>
<url-pattern>/servletpath/*</url-pattern>
</servlet-mapping>

$ jar tf httpdump.war

Sat Aug 26 15:58:54 CEST 2000:<E> <WebAppServletContext-httpdump> Error loading servlet: httpdump.HttpDumpServlet

So, it seems the WLS has interpreted the <servlet-mapping> tag in the
DD correctly, but is then looking for the servlet class in the wrong
places..?
My system configuration:
$ java weblogic.Admin t3://localhost:7001 VERSION
WebLogic Build: 5.1.0 Service Pack 5 08/17/2000 07:21:55 #79895
$ uname -a
Linux localhost.localdomain 2.2.14 #1 Wed Aug 16 01:57:42 CEST 2000 i686 unknown
$ java -version
java version "1.2.2"
Classic VM (build 1.2.2-L, green threads, nojit)
$
Any hints?
Thanks,
Olaf

Hi,
we jared our servlets up and placed them in /WEB-INF/lib/....jar. The
mapping is working without any problems.

Conversation: mapping paths to servlets doesn't work anymore in SP5 ??
Subject: Re: mapping paths to servlets doesn't work anymore in SP5 ??
Yes, this is already a known problem in SP5.
Fix will be available in the upcoming service packs.
I guess the workaround is to put servlet classes in servlet classpath.
Sorry about the regression.
