Usr/sbin/pppd and usr/sbin/vpnd.  What are these?

In performing a permissions repair, it listed usr/sbin/pppd and usr/sbin/vpnd as having been modified and unable to repair. I also performed a permission repair by booting from the Leopard disc, and got the same results.
What are these, what do they do, and where are they? I couldn't locate them through a search.

As Limnos says, don't worry about the messages.

pppd and vpnd are daemons (faceless helper programs). pppd is the Point-to-Point Protocol Daemon, commonly used by dial-up modems and DSL and other kinds of network links. vpnd is for VPNs, or virtual private networks.
Read the man pages for pppd and vpnd for more information (possibly even more than you wanted to know).
And as Limnos says, they live in directories that don't get searched.

    Do you happen to have an Android?  If so and depending on what version there is a great data usage analyse tool built-in.  See if you can go to Settings -> Data Usage  from there you can pick a current or previous billing cycle and then use the vertical sliders to select a date range and it will filter the usage data per app to show you exactly what app(s) were using data during that time frame.

  • What are these processes and how do I prevent them?

    For many years, many have complained of external drives that are in standby/sleep spinning up for no apparent reason.  From the user's point of view this is unnecesssary, but to make matters worse, the system usually stops everything else while waiting for the drives.
    I have a Mac mini that I use as a home theater pc.  The media and backups are on a 5-bay enclosure (no RAID) attached by USB.  While watching a video, the unused drives will go into standby mode, which is good.  But then, with no user activity, they will spin up, freezing the video and everything else, which is not good.  As these are slow drives and spin up sequentially, this can take 10-20 seconds.  This may happen once or twice an hour, but sometimes more frequently.
    In looking into the causes, I have turned off time Machine (after putting these drives into the Privacy section for good measure).  I also prevented Spotlight and fsevents logging with the following:
    mdutil -i off /Volumes/<drive1> /Volumes/<drive2> . . .
    cd /Volumes/<drive1 and then repeat for other drives>
         rm -rf .fseventsd .Spotlight-*
         mkdir .fseventsd
         touch .fseventsd/no_log .metadata_never_index
    As far as I can tell this has worked to stop those processes from accessing the drives after they are mounted, but the problem persists.  To find out what else might be causing them to wake up:
    sudo fs_usage -w | grep -e Volumes/<drive1> -e /Volumes/<drive2> . . .
    and here is what I found last night (actually didn't use the -w last night, thus it is cut off):
    18:35:36  fsgetpath   /Volumes/XBMC         0.000026   SSDragHelper
    18:35:36  fsgetpath   /Volumes/Stuff        0.000006   SSDragHelper

    18:55:36  fsgetpath   /Volumes/MacBackUp    0.000003   GoogleSoftwa
    After looking into the Google process, I was surprised to find the tentacles that Google puts into your system, and ripped every bit of it out that I could.  But I have no idea about what's going on with SSDragHelper and System Prefe (presumable System Preferences).  This must be OS X itself?  What are these processes doing, and is there any way to prevent them from accessing these disks in this way?

    Thanks for the reply Hen3ry.  Looks like you've done a lot of investigation.  For me, fs_usage entries accompanying spindown are not problems - I'm happy if the drives spin down.  My problem is the spinups.  But still, I don't think it is necessary to time the fs_usage entries with spinups.  If you grep for the drives you're concerned about, you will see any process that would potentially wake them up.
    Because my understanding is limited, I also am more concerned with the process/application that is accessing the drives than with the functions or commands they are sending.  And the values that are returned by those functions are way beyond what I can deal with.
    It's interesting that you've found a difference between your old and new drives.  Could you specify the enclosure and drives in each case?
    The StorageStatus app looks interesting; thanks for the tip.
    Here's a summary of what I've done so far, which I think is working.  I need a few more weeks to know for sure.
    How to prevent unwanted drive spin-ups
    If you are actively using the computer that the enclosure is attached to, nothing on God’s green earth will stop OS X from waking them up after some user action, even ones that seem to have nothing to do with the external drives.  But if you leave the computer alone while some application is running, like watching a movie or downloading a file, you have a fighting chance of coaxing OS X into leaving the uninvolved drives alone.
    If the drives are shared with any other computers over a network, eject them on those computers
    Otherwise, OS X (AppleFileServer) will poll them every 10 seconds.  This might not be bad if you want to just keep the drives spinning and the other computer stays awake.
    Third-party apps
    Make sure no apps are running that might access your drives.  Google runs some processes that do this (maybe I’m naïve, but I was so shocked I removed chrome and every other trace of Google from my Mac mini system). Another is iStat and any utility that monitors SMART status in the background.
    Don’t let Spotlight index or search the drives
    Spotlight is persistent, and it may be necessary to take a variety of steps to stop its various processes (mds, mdworker) from accessing the drives and waking them up.  In other words, kill it, drive a stake through its heart, then burn the body:
    In System Preferences > Spotlight, add the drives to the Privacy pane.
    Add a file called .metadata_never_index to the root of each drive (note the leading period).  The easiest way to do this is in Terminal
    touch /Volumes/<drive1>/.metadata_never_index
    Tell Spotlight AGAIN to keep away from the drive:
    mdutil -i off /Volumes/<drive1> /Volumes/<drive2> . . .
    Finally delete the Spotlight folder from the drive.
    rm -rf /Volumes/<drive1>.Spotlight-*
    Stop fseventsd from logging in the drive
    This is easy, just putting a no_log file in its folder.  I have found that rarely it still writes some files in there, but it doesn’t seem to do so when it causes problems, so . . .
              rm –rf /Volumes/<drive1>/.fseventsd/*
         touch /Volumes/<drive1>/.fseventsd/no_log
    Finder sidebar
    Some people say that if the drives show in the Sidebar of Finder windows, the Finder will be checking them.  I’m not sure. But to be safe, in Finder Preferences > Sidebar, uncheck External Disks.
    Just say no to Time Machine
    On the home theater mac itself, regular backups shouldn’t be needed.  You should be able to just turn Time Machine off.  However, it is probably sufficient to simply open System Preferences > Time Machine > Options and add the drives to the list of locations to exclude from backup.
    Second, local backups can be disabled with
    sudo tmutil disablelocal
    Look for other culprits
    If the problem persists, use fs_usage, which generates a real-time log of filesystem activity. There is so much going on that you need to use grep to restrict the output to entries that involve your drives. The entries that accompany your drive spin-ups are the ones you really want.
    sudo fs_usage -w | grep -e Volumes/<drive1> -e /Volumes/<drive2> . . .
    Now leave the keyboard and mouse alone, as many things you might do will cause the drives to be accessed. You probably want to find what does it when you’re not actively interacting with the computer.  It’s not really necessary to wait for your drives to sleep and see what wakes them.  Any activity you see would probably wake the drives if they were asleep.  When you see some activity and want to stop and examine, type Control-C to stop the output.  On the far right of each entry is the process or application that accessed the disks.

  • What are these ports 989, 1021, 1033 and why are they always ON?

    I have noticed unknown network traffic on Activity Monitor, even I close all application, AM still shows there's about 1~2 KB (Data received).
    So, I open a Terminal and check by 'netstat' command. I notice there's some unknown tcp connections established. Is there anyone know what are these ports, and is it normal to have them ON all the time ?
    $ netstat -n | grep EST
    (..omited)
    tcp4 0 0 127.0.0.1.1033 127.0.0.1.989 ESTABLISHED
    tcp4 0 0 127.0.0.1.989 127.0.0.1.1033 ESTABLISHED
    tcp4 0 0 127.0.0.1.1033 127.0.0.1.1021 ESTABLISHED
    tcp4 0 0 127.0.0.1.1021 127.0.0.1.1033 ESTABLISHED

    These ports are some of those used by the NetInfo subsystem which keeps track of your computer's users, groups, and some other information about its configuration. Since the IP addresses listed for those connections are all 127.0.0.1, your computer is connecting to itself; having these open isn't a cause for concern.

  • What are these startup items and are they harmfull

    Hello
    I Have a M55-S325. I have noticed some items on my startup list in system Configuration Utility
    TCtrlIOhook.exe
    TPSMain.exe
    Ltmoh.exe
    AGSMMSG.exe
    Apoint.exe
    TFncKy.exe
    So My Question is What are these and are they harmfull
    if so how do i remove them.
    PLEASE HELP

    Hi David,
    The items you have listed are genuine items use by your operating system although they may be stopped if you wish without doing any real harm. It will largely depend on whether you want to use any of the functions in which they are involved.
    For example, TCtrllOhook.exe and TPSMain.exe are associated with the Toshiba power management utility.
    Ltmoh.exe and AGRSMMSG.exe relate to you installed modem.
    Apoint.exe is associated with you pointing device (Touchpad or whatever).
    TFncKY.exe is related to the Toshiba function keys feature.
    Obviously, if you are not using your internal modem then the modem related items can be stopped without any ill effects, similarly the Toshiba Function keys.
    regards,

  • What is watch point and break points?what are there types?

    what is watch point and break points?what are there types?

    Static Breakpoints
    Static breakpoints are always user-independent if there is no specification of a user name. Once a user has inserted the statement BREAK-POINT or BREAK name in an ABAP program, the system always interrupts the program at that point for that user or only for the user name. This procedure is only useful in the development phase of an application when program execution is always to be interrupted at the same place. For more information, refer to the chapter Static Breakpoints.
    In HTTP sessions, a static breakpoint is skipped if you did not set additional dynamic HTTP breakpoints in the editor of a BSP page. Instead, a corresponding system log entry is written, which can be checked using transaction SM21.
    Dynamic Breakpoints
    Dynamic breakpoints are user-specific. Therefore, you should use them if you only want the program to be interrupted when you run it yourself, not when it is being executed by other users. All dynamic breakpoints are deleted when you log off from the R/3 System.
    Dynamic breakpoints are more flexible than static breakpoints because you can deactivate or delete them at runtime. They have the following advantages:
    · You do not have to change the program code.
    · You can set them even when the program is locked by another programmer.
    · You can define a counter that only activates the breakpoint after it has been reached.
    Special dynamic breakpoints are useful when you want to interrupt a program directly before a particular ABAP statement, a subroutine, or an event, but do not know exactly where to find it in the source code. Event here is used to refer to the occurrence of a particular statement, for example, or calling up a method. Special dynamic breakpoints are user-specific. You can only set them in the Debugger. For more information, refer to the chapter Dynamic Breakpoints.
    In HTTP sessions, the system stops both at static and dynamic breakpoints if a dynamic breakpoint was set in the editor of a BSP page before program execution.
    Watch point are used to put logical break point for a certain condition..Example..If you want to know when the internal table is getting append..Then you have to give the program name and the internal table in the watch point.. 
    Steps to create a watch point.
    Start debugging '/H'.
    In the debugging screen press the create watch point button in the application tool bar..
    In the program give the program name..
    in the field give the field name.
    In the relational operator given '='
    In the comp. field/value give the value ..
    Hope this helps..
