Unix whizz help me please!
My DVD drive on my 20" intel imac is failing to eject the disk. It won't come out. I have done everything like restarting with the mouse held down etc etc. I am going to buy a cheap external DVD writer as a solution. The drive however is making a noise every 10 secs in what I guess is in an attempt to read the disk or eject it? What ever the noise is I want it to stop! Is there a command I can type in the terminal to kill or disable the drive so it quits trying to do what it is doing?
Thanks in advance.
Martin.
some of the following may be redundant ...

Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this:
Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
/usr/bin/drutil eject.
If this fails then try this:
Boot the computer into single-user mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
Once you get the DVD ejected I would reboot from it. Open Disk Utility from the Utilities menu when the the menubar appears right after you select your language and click on the Continue button. Do the following:
1. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
2. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
Quit DU and return to the Installer. Complete the installation.

Hijacked mac-unix gurus, help me please!
This is a very weird situation, please bear with me:
My ibook and desktop g4 were running 1.3.9, the plain consumer version. Or so I thought.
But here is the weird part: after splitting with my ex, I found i had no root access on either of my macs - and no way to regain it.
1.there is a Security Agent installed
2.a Thawte security cerificate/ w key is in the ibook's keychain, the password encrypted and obviously news to me.
3.the ibook HD is locked.
3.Remote desktop agent, apparently running from ibook, controlling every aspect of the desktop.
4. crucial logs are either missing or encrypted.
To clarify, both machines are mine, but the ibook was used primarely by my ex, who claims to be computer illiterate.
Who also denies any knowledge of anything.
And now for the most bizarre part: the ARD, and network manager parts are hidden - the machines "look" ordinary.
The whole operation is camouflaged in the most mind boggling way. By sheer luck, I stumbled on the ibook's "other" interface - just enough to note that the menu is different, and there are weird java scripts all over the place that trigger actions in ways I never saw in Kansas:
example a: itunes extra library stashed in documents folder, which, when imported, added one mp3 file to itunes, but it was no tune - it's name: "connect to server".
example b: expander alias on the desktop - if clicked launches the classic- which runs without showing in the dock, and launches something else...
There are modifier keys involved, but i have no idea what they are - pressing the right ones gets you "in" (to OZ?), otherwise a bogus system preference is launched - I found the script that spells this out, AFTER I have seen it happen
So, there is a very sneaky system within the system, but also very protected:
Every time I wipe, zero all data etc, on a drive, after installing a brand new system....it then "rebuilds" itself to whatever it was before. Yup, complete with email addresses.
So there is apparently an invisible volume on all my drives, where there are munchkins that track and rebuild whatever I
"screw up" - most of all, tell the installer/disk util. how to "wipe".
After 3 weeks of no sleep and sifting through hundreds of pages of logs and scrambled files...I realized whatever is on these two machines is certainly not a case of someone trying to hide the **** surfing; furthermore, I took the plunge and installed a new HD on the ibook, in hope to get rid of it all. At first, the Panther would not install on the new drive - but after I removed the airport card and the extra memory - the installation was fine.
So, what in the world am I dealing with? Everyone I talk to says you can't hardwire any data into macs, but everything points to some doctored part.
True, the new drive does not have the secret volume with X-serve on it, but SOMETHING is still there -sorry, I sound like Aliens script, but i have been reading logs on the ibook and there are a lot of weird apps, jobs and actions trying to launch, then quitting when they don't find the mother ship, that is the server, ftp or whatever.
Please help me out.Until this, I knew nothing about java, and now i am in java ****.
I basically lost both my macs, and what's worse, my IP and my personal name have been whoring on the web, and I have no way of tracking the ftp sites, it's all encrypted.
The cops tell me no laws were broken because I lived with that person - who denies doing it, anyway.
I am supposed to believe there is a Trojan, or a hacker who made it through the password protected network, reformatted my drives, installed the server software, ARD manager, iChat
Agent, Security Agent, deleted all important installation logs, oh, and "upgraded" my ipod as well.
I have text files and many screen shots, if anyone is interested.
Thank you for having the patience to read through this rant.
ps: just to save some time: open firmware, single user, sudo, password reset - nothing works in that sneaky ****.
Thank you."But here is the weird part: after splitting with my ex, I found i had no root access on either of my macs - and no way to regain it."
Here's a question: have you gone in to NetInfo Utility confirmed that root is enabled under the Security menu?
"there is a Security Agent installed"
There is always a security agent installed. How do you think this security agent is messing with your system?
".a Thawte security cerificate/ w key is in the ibook's keychain, the password encrypted and obviously news to me."
That just means your ex surfed the web and bought something from a merchant who issued her a Thawte certificate. When that happens, OS X will offer (or perhaps automatically) store it in the user's keychain.
"The ibook HD is locked."
What do you mean by that? you should not be able to copy files to system directories or other user's directories. without first gaining administrative access. Do you have an admin level user account? Did your ex? I suppose it's possible she disabled your account's admin privileges. You can check under Accounts in System Preferences (you may have to boot from your Panther install disc and use it to reset your ex's password
"Remote desktop agent, apparently running from ibook, controlling every aspect of the desktop."
What do you mean by every aspect of the system? Is it controlling the mouse? Is it controlling behaviors or configurations? Does it show up in Activity Viewer?
"crucial logs are either missing or encrypted."
which logs?
"The whole operation is camouflaged in the most mind boggling way. By sheer luck, I stumbled on the ibook's "other" interface - just enough to note that the menu is different, and there are weird java scripts all over the place that trigger actions in ways I never saw in Kansas:"
Please tell us how you stumbled on the other interface and what sorts of actions these javascripts trigger.
"There are modifier keys involved, but i have no idea what they are - pressing the right ones gets you "in" (to OZ?),"
how do you know pressing a certain combination gets you in? in to what, exactly?

How to run robocode? Help me please
Hi everyone,
I try to develop java applets and programs for a software development course.
We have to work with the software called "Robocode" which a program about writing codes to see little robots fighting each other.
Actually my real problem is that when I launch the file robocode.command I just have an error message saying "The file “robocode.command” could not be executed because you do not have appropriate access privileges."
Did one of you ever met this type of problem? if yes help me please because even by creating a super user account nothing worked and to say the truth I'm really disappointed about that.
Thank you =)Actually my real problem is that when I launch the file robocode.command I just have an error message saying "The file “robocode.command” could not be executed because you do not have appropriate access privileges."
Under Mac OS X any file that ends with .command is assumed to be a double-clickable Unix shell script. However, the file needs to have the Unix execute permissions bit set.
Applications -> Utilities -> Terminal
chmod +x robocode.command
I'm not sure any of the Apple discussion forum would be idea for discussing "RoboCode", however, the closest might be something like Mac OS X Technologies -> Software Development 101
<http://discussions.apple.com/forum.jspa?forumID=728>
If there are Unix specific questions, such as setting the execute permission bit on robocode.command file, then the Unix forum would be the best place to ask

Help needed please, everytime I try to update the software version on my iphone it comes up with a message saying it could not be completed and is now frozen with the apple picture and progress bar on it. Do I unplug it and hope the macbook pro sees it again, I also stupidly did not back up before starting the download which I realise I will have to go back to the previous back up. This keeps happening, everytime I do this type of update, I'm starting to think I should just give up on updating my software on the Iphone. I thought it was happening because I was using a window based computer to do the updates, this time I used my Macbook Pro. Please somebody help

in the previous version of Number, the menu table in table options, there is an option that gives me the option: the Return key moves to next cell. I do not see this option in the new number. can you help me please?
Hi silvano,
If you use a regular pattern when entering values, press enter (return) after entering the last value in a row. That will take you to the first Body Cell of the next row.
Start in Cell B2
1 Tab 2 Tab 3 Enter
4 Tab 5 Tab 6 Enter
7 Tab 8 Tab 9 Enter
Now you are ready to type into B5 .
Another way that some people find easier is to enter one column at a time
Start at B2
1 enter
4 enter
7 enter
etc.
Now start with C2.
Use whatever suits your work flow.
Regards,
Ian. -
