the only reason that this is a bit strange is that my computers name is HAL, and not qtsoftware. am I wrong in the assumption that the first phrase is supposed to be the computers name? because I checked in the sharing pane of system preferences.
I'm am very new to unix, and this has been puzzling me.

Look at
*echo $PS1*
It most likely has h somewhere in the string.
According to "man bash", this is
*\h the hostname up to the first `.'*
Generally this is the same value as
*hostname -s*
Often times when getting a DHCP assigned IP address, corporate servers also have names associated with those IP addresses which get associated with the 'hostname'.
Your system should still be accessible via HAL.local for other Macs on your subnet where Bonjour can be seen by other systems.

  • My new macbook pro seems to be acting strange. Maybe something is turned on that I do not know about?

    I shut the lid, the brightness went all the way down and also when I turned it on after a shutdown, the display was set to a custom screen size, similar to the size of a TV's widescreen feature. Any ideas what is going on?

  • Safari is acting strangely on several counts

    For the last several days, Safari is acting strangely on several counts. I haven't downloaded any updates or plugins recently, and I am not aware of any Safari viruses on Mac OS X, so I'm totally lost here. Please help!
    1. Periodically, Safari will stop loading a page completely. So it will start and then the url bar will be partially blue and the circle will keep circling but nothing will happen. Once it does this on one tab in that window, it will start doing it on all new tabs opened up in that window, but any original tab there might still go through. If I close the window and reopen another window, all sites on all tabs will go right through. I tried disabling DNS prefetching, and that helps Safari behave for a few minutes, then it goes back to such strange behavior. I tested using my wireless and using a different network, and it happens on both, so it's not my router. Sometimes, opening a new window doesn't help. So I shut down Safari and restart. Sometimes that doesn't help either, so I end up having to reset Safari. Obviously, having to reset Safari multiple times a day is neither productive nor ideal.
    2. When it does that url thing, it also seems to become incapable of completing from history or bookmarks. So for example, if I open a tab and type a website name, it won't complete it, even though I have that bookmarked. Generally when that happens on the first tab of a window, I can pull up the site from bookmarks and it will load immediately. But the next tab I open in that window, will do the webpage not loading business I described in #1 above.
    3. A short while ago, i tried resizing a window and it did the strangest thing where it would expand the window space, but just give me a "gray area" rather than expanding the whole web page. I closed the window, opened a new one and resizing worked fine again.
    4. A short while ago, another strange happening: everytime I opened up a new tab in the window and loaded a site, it would merge that tab with my old tab and delete the first tab, so at any given time, it was just a single tab window. I closed the window and reopened, and voila normal tab behavior again.
    Strangely, if I have two windows open - as I often do - only one window will be affected by such strange behavior. The other one will function normally. But such odd behavior is not limited to instances when I have two windows open. It's also happening when there's one window open. For reasons I do not understand, it seems something in the processes of a window gets corrupted after a little while on Safari and that window starts acting strangely.
    Odd and irritating and difficult. I'd greatly appreciate your help!
    I'm using Safari 5.0.6 on OS X 10.5.8... thanks!

    I don't see anything in your post regarding the Safari cache. BTW, a "reset" does not empty the cache.
    From your Safari menu bar click Safari / Empty Cache. Restart your Mac, try Safari.
    If that didn't help, quit Safari if it's open.
    Go to ~/Library/Caches/com.apple.Safari
    Move the Cache.db (or ApplicationCache.db) file from the com.apple.Safari folder to the Trash.
    Try Safari.
    If nothing above helped, make sure there's enough free space on the startup disk.    Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you have a minimum of 15% free disk space.
    If nothing above has helped, try Safari in another user account. If you see the same issues there, log back into your admin account.
    Launch Disk Utility. Select the startup disk in the panel on the left then select the First Aid tab.
    Click:   Verify Disk  (not Verify Disk Permissions)
    If the disk needs repairing follow the instructions for Using Disk Utility to verify or repair disks.

  • New Socket() acting strangely under Windows

    Hello,
    First a little background:
    I have a client application that connects to a server application through a socket. The client first checks to see the server is 'reachable' using the .isReachable() method. If this return true, all is good. If it returns false, the application sets up to use a Microsoft Windows DUN connection and VPN to connect to the server. This is handled through a 3rd party .jar file called jdialup. Oh, one more thing, the client pc is connected to the network through a hub. In other words, the pc is connected to a hub. The hub is connected to the network using it's up-link port... Everything so far is pretty simple enough...
    Now the issue:
    If I disconnect the network cable from the back of the pc and run my client application, it says that the server is not reachable, which is fine. The application then dials out to our ISP and connects to our VPN. The client application connects to the server application through a socket and sends the request and receives the response. The client then disconnects. Everything is GOOD.
    Now, if I disconnect the network cable from the up-link on the hub, thus removing the client pc from the network, this is where the strangeness happens! I run my client application, it again says that the server is not reachable, which is fine. The application again dials out to our ISP and connects to our VPN. This is fine. Now though, when I attempt to make the socket connection to the server, it times out! The actual call to
    Socket socket = new Socket(ipaddress, port);times out...
    This seems very strange to me... Any ideas?
    PS: In both situations when I connect to the VPN, I can ping and telnet to the server. It is the Socket call that is acting strange...
    Thanks,

    I've been following this and I'm baffled by the
    discussion so far. Has the thread been trimmed? I believe we got off on a tangent, but the problem is that in certain circumstances the client application tries to connect to the server application the call the 'new Socket()' times out... You will have to read my original post...
    Anyway, I believe that I have figured it out. It was related to the gateway option in the network setup on the client pc.
    Originally I had the gateway option set to be an ip address internal to our network. Our network guy said that in this situation, I needed to set the gateway to an ip address outside out network. When I did that, everything now work beautifully. Why? I have no real idea as I am not a network guy, but it work now and I am happy...
    Thanks for everyones help and sorry for all the confusion.

  • Help! My keyboard is acting strange : (

    Help! My keyboard is acting strange. I just moved and when I started to type in my Mac Book Pro after not using it for a few weeks, every time I typed certain letters, two other letters in the same column appear (eg: when I type c, edc appear or frv when I type r). Numbers seems to work well though. Any ideas?

    When you moved did you pack up your mac and did it have anything pressing on the lid and keyboard area?
    Try a SMC reset and if that doesn't fix it you need to go to apple and probably have the keyboard replaced.

  • Disk utility is acting strange

    Hello,
    My Disk Utility is acting strange: I get inconsistent results on First Aid.
    I get either "Volume Bit Map needs minor repair", "Keys out of order", "Invalid node structure", "Invalid volume file count", "Invalid volume free block count", or "Volume Header needs minor repair". I click Repair Disk. And after some clicking, the problems seem to go away, showing “the volume appears to be ok”. But the problem is that when I hit Verify Disk a couple of times, or a few minutes later, Disk Utility finds these problems again.
    Does anybody know what might be going on here? This is my external backup drive; my internal Macintosh HD is fine. Well Disk Utility says so....
    Thanks

    Verify Disk performs what is known as "live verification" and may sometimes give spurious errors. This is what might be happening. To be sure, this really must be done from Disk Utility booted either from an external Volume or from the Install Disk. I would go straight to Repair Disk and not bother with Verify. Permissions Repair, on the other hand, should be done from the normal boot Volume.
    How were you doing "Repair Disk"? You probably know that option will be dimmed out when you are booted normally.

  • ZEN MICRO PHOTO ACTING STRANGE PLEASE HELP.

    I have had my Zen MicroPhoto for a bout a month now and it is great! I use it quit often. However just yesterday, it began acting strange.... It deleted many of the files that I originally transferred to it and whenever I start it up, it says "rebuilding library" Also it does not display the now playing info for teh current track. it only displays "choose a track from music list" It will play songs and stuff but it just seems strange..... I do not know what to do about it.... Should I reinstall the firmware or what? please someone help me.... I would appreciate any advice on the subject... I freakin' love using my ZenMicro. help me save it. Thank you.

    aaron78: Follow the advice in the section "My Zen is not behaving properly, won't startup, or goes into rescue mode. What should I do?" in the FAQ.
    Snoweagle: Reloading the firmware shouldn't erase the data, although you should ALWAYS keep a backup.

  • Powerbook acting strangely....help!

    Hello!
    My Powerbook g4 17 has been acting strangely the past two days. It all started when I had both Safari and iPhoto open. I got the Beach ball of death and my computer froze (I had been getting the SBBOD on occasion, but never had it caused a full blown freeze before). I tried all the force quit commands and finally I had to manually shut it down. It had trouble restarting, it would chime but then it wouldn't get past the first screen with the grey apple symbol. I turned it off and let it "rest" overnight. The next day it turned on fine, but the computer's "thinking" noises sound different. More of a buzz now than the usual clicking and whirring noises. The power button also makes a strange "BEEEEOOOOooooop" noise when I turn it off, which is also new.
    To make a long story short, I tried to run disc utility and it froze on me again when it finished. I had to hard start it (and again, and again, and again...)and it won't go past the first screen UNLESS I let it sit turned off for at least 5 minutes. Once I do manage to get it turned on, it acts fine for maybe a half and hour or so until it slows down (thinking gets labored) and freezes on me again.
    Any ideas on what may be going on? I'm worried it's something really bad.....

    Thank you BGreg.
    I have 27GB free out of my 80GB drive, so no issue there...
    I tried to do the boot up with the OS X install cd witn no luck. I was on the phone with AppleCare last night for over an hour and after trying many different things, it seems I am going to have to mail it in for repairs.
    Here I was hoping it'd be something simple.
    And of course, I backed up as much as I could. I'm crossing my fingers!

  • My G5 recently began to act strange. I could no longer print ton any printer. all of my Adobe software would crash on startup as did Safari. tried to reload the printer software and was denied as I was no longer recognized as the administrator. any fixes?

    my G5 recently began to act strange. I could no longer print to any printer and all of my Adobe software and Safari would crash on startup.  attempted to re-install my printer software, but was denied as the computer no longer recognized me as the administrator even though i am the only account on the computer.  Performed a system install (w/ bakup of previous), this seemed to work for about two days and the problem has returned with other software (Excel) crashing on startup.  does anyone have any suggestions?  do i need to erase the harddrive and start over?

    I suggest you backup you important data!
    I suspect the harddrive is going bad.
    Run disk utility. verify disk & verify permissions. 
    Run hardware diagnostics. 
    I not sure of a good way of telling if the harddrive is going bad.  There is software to test harddrive.  Don't know of free stuff for mac.
    Considerng that the hd is 7 plus years old this isn't a surprise. 
    Suggest replacing hd.
    If your not up to that, get an external hd.
    You need an external Firewire drive to boot a PowerPC Mac computer [ a few G5's will boot from USB ].
    I recommend you do a google search on any external harddrive you are looking at.
    I bought a low cost external drive enclosure. When I started having trouble with it, I did a google search and found a lot of complaints about the drive enclosure. I ended up buying a new drive enclosure. On my second go around, I decided to buy a drive enclosure with a good history of working with Macs. The chip set seems to be the key ingredient. The Oxford line of chips seems to be good. I got the Oxford 911.
    Has everything interface:
    FireWire 800/400 + USB2, + eSATA 'Quad Interface'
    save a little money interface:
    FireWire 400 + USB 2.0
    This web page lists both external harddrive types. You may need to scroll to the right to see both.

  • Some adobe fireworks cs5 panel acting strange.... how to fix it

  • IPad mini acting strange. Apps open and close randomly. Any ideas?

    My iPad mini acts strange. Apps will randomly open and close and I have no control over it. I have reset it to factory and started all over but it is still doing it. Any ideas on what I should do?

    If the unit has NEVER been jailbroke, first try a system reset.  It cures many ills and it's quick, easy and harmless...  Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  It could take well over an hour!  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow the on-screen directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore, go into Recovery Mode per the instructions here.  You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again.  Also, if you have IOS-7, read this.

  • IBook acting strange...erase and reinstalled...it's starting to be strange

    My iBook was acting strangely...I can't connect to the wireless server, though ISP, network settings and Airport are all correct and the connection is visible and the strength of the connection will change. I cannot load any internet pages. In addition, my iDisk icon disappeared, then on restart, it reappeared, but I have no access to it. A "copy of previous iDisk" then appeared on my desktop with all of the contents, but I can't move them from this version as it says I do not have access. So, I started looking at the logs, to see what, if any, errors there were. I didn't have access to the security log and a few others - although I'm the only user account on this computer. Needless to say, I'm no expert so I "spotlighted" some of the things showing up in the logs. Spotlight returned articles on Apache and XTools (Xcode?) - neither of which I installed (I think Apache might come included). I looked and sure enough, XTools was on my hard drive with many, many files - most with the name or extension of pb or pbx. I started to dig a little deeper in the program and noticed some scripts in the vein of when user enters/types "xyz" initiate process or replace with "zyx", etc. I saved some of these files to the desktop, powered off and restarted. When I opened the desktop after the restart, all of the files were in the trash - not by my doing. I removed them and locked them to the desktop until I could figure out what happened. Then, they disappeared, my computer shut down and when I tried to restart, I couldn't get past the spinning gear.
    I took this to the store, they checked it, said they could recognize a drive, that I should archive and reinstall. I did this, things still acted strangely. I called AppleCare, they said to back up everything and reinstall.
    I did this, now am finding repairs are needed through disk utility for security and authorization priviledges. I repair, go back in a few hours, run it again, just to satisfy my curiosity and the same repairs are needed for disk permissions.
    A friend has uttered the horrible "trojan horse" phrase to me...as I download regularly from LimeWire. I'm not sure what a next step would be to free the iBook of it's quirkiness.
    Sorry for the long post...but it's been an eventful few days.
    iBook G4   Mac OS X (10.4.2)  

    You can ignore any permission repair that states "We are using special...". I'm not sure about Tiger but Panther has a few others that come up if the cron maintenance scripts have run.
    Other than the repeating permission repairs, is it running OK now?
