How Enable network logging

Hi,
I'm trying to troubleshoot network connectivity problems and I was asked by the IT group to provide them with 'network connectivity log'. I've sent them a copy of the system.log from console, which i don't think says much. I have seen some mention of "ipconfig setverbose 1" in terminal, but it seems that it is not a valid command under OS10.3.9 Is there a way under 10.3.9 to get any kind of detailed logging of the network traffic?
Background : some of the macs in our office get "dropped" from the network after being "on" for a while. Dropped means they get valid IP addresses from DHCP but cannot communicate any further. rebooting, changing 'locations' don't work.
Thanks

Costas,
tcpdump might be what they're looking for. it will put the network interface in to promiscuous mode, allowing it to capture all the network packet that it sees.
sudo /usr/sbin/tcpdump -w tcpdump.out -i en0
after capture the information that you need. use Ctrl+C to stop capturing and close the output file.
to read the file.
/usr/sbin/tcpdump -r tcpdump.out | more
you can use other options to filter either what's captured. or to limit what you look at in the output. The options I've shown will capture everything that passes you interface.
tcpdump comes with OS X. There is also ethereal, with you'll have to download, but it has a graphical interface, and if I remember correctly requires X11.

  • Utterly Stuck enabling network log-in

    Hi,
    Having real problems setting up a new 1.5.3 server running on a Mac pro.
    Basically my network is the Mac Pro, a macbook pro, and time capsule router.
    I have created a new account "office" on the server, connected to the Open Directory via Directory Utility on the Mac Book Pro, created an AFP sharepoint and set it to automount, and then set the home folder for office to reside in this sharepoint.
    Once the Directory Utility is run, I get an extra login option in login items on the mac book pro, but i cannot log in with supplied username and password. Everything i try get's rejected.
    I also cannot log-in from the Server into this account.
    Any advice would be appreciated, just spent the last 8 hours trying to resolve this and I am tearing my hair out at the moment!
    thx

    Hi
    Which directory node was the account created in? Can you connect to the created home folder using the Go Menu > Connect to Server > Server IP Address from the client?
    Generally you get the "Logging into the account failed because an error occurred" message because (a) DNS is poorly configured or confused in some way. You'll see the error message almost immediately if that is the case or (b) It's either an authentication method or user account problem or both. There is a usually a delay before the error message is displayed or (c) Time sync issue. Usually quite a long delay before you see the error message.
    On the client side log back in with local Admin account and inspect the system.log as well as the Directory Service.log in Console. It might give a clue as to what is going on?
    On the Server inspect the same logs in Server Admin (or Console) to see what is being logged there. In addition you could launch terminal and issue:
    sudo kadmin.local -q list_principals
    You should see an entry for [email protected] amongst others.
    If its not there then something has 'kiboshed' slapd. Effectively you don't really have an OD Master and its ability to provide auto-mounting networked home folders as well as anything else will be 'hamstrung'.
    The above suggestions are for a Server configured in Advanced as I don't do Standard or Workgroup, sorry.

  • How to enable fnd log in self service page

    Hello,
    In professional forms, we can enable fnd log using the profile options "FND: Debug Log Enabled" to Yes and "FND: Debug Log Level" to different levels.
    Similarly, can we do the same with Self Service page? how and where can i see the log results? Also when i'm running the selfservice page from jDeveloper, is there any possibility to see the entire log?

  • How to enable JCo logging

    I know I've seen this somewhere, but now that I need it, I can't find it.  I've spent two hours searching all the forums.  Can someone tell me how I enable JCo logging?  I have a JCO/Java program that works fine from the command line, but doesn't work when I try to use it in a Tomcat servlet.  None of the log files that I can find have any errors in them, but it appears that the call to JCO.createClient fails in the servlet.  I've read all of the posts about putting the JCo jar file in the servlet's lib directory and copying sapjcorfc.dll to Tomcat's bin directory, but no luck.  I'm hoping that there is some way that I can get JCo to give me a log that will indicate what is going wrong.  Thank you for your help.

    <b>SAP Note 723562</b>
    2. Runtime loading mechanism
    When an application references a JCo class for the first time it will be loaded by the associated class loader. During this process JCo's static initializer will be executed. This routine will search and load the JCo JNI library by using the following algorithm:
    1. Try to load the sapjcorfc library from the same directory where the sapjco.jar file or the JCo class files are located.
    2. Search the sapjcorfc library along the directory path defined in the java.library.path system property from left to right and if found load it from there.
                Note: If this property is not set manually, the JVM will usually set the OS specific library path environment variable as the default java.library.path system property at startup.
    1. Let the JVM handle the loading of the sapjcorfc library by delegating this task to its System.loadLibrary(String) method.
    JCo's JNI library is linked with the native RFC library. So when it is loaded the operating system will try to resolve its dependencies by loading the native RFC library, too. Usually, this will be done by searching for the first occurrence of the rfccm | librfc32 library along the directory path defined by the OS specific library path environment variable from left to right and load it.
    If the sapjcorfc library and/or the rfccm | librfc32 library cannot be loaded, you will get an ExceptionInInitializerError from the JCO. <clinit> method saying that it could not load the middleware layer com.sap.mw.jco.rfc.MiddlewareRFC. This error message may be caused for one of the following reasons:
    The sapjcorfc library cannot be found by using the above described algorithm, because you unintentionally installed it to the wrong directory or forgot to specify its directory in the OS specific library path environment variable or alternatively in the java.library.path system property.
    The rfccm | librfc32 library cannot be found because you unintentionally installed it to the wrong directory or forgot to specify its directory in the OS specific library path environment variable.
    The version of the sapjcorfc library found via the sapjco.jar directory or the java.library.path system property is not the required version (the version numbers and dates of the JCo middleware and the JCo library must be equal).
    The version of the rfccm | librfc32 library found via the OS specific library path environment variable is too old (for example you forgot to copy the librfc32.dll to the <WinDir>\system32 directory and an older version is loaded from there).
    The sapjcorfc library, the rfccm | librfc32 library or both lack the execute permission flag.
    The sapjcorfc library, the rfccm | librfc32 library or both do not have the same bit width as the JVM.
    The sapjcorfc library, the rfccm | librfc32 library or both were from a different JCo distribution and are not for use with your operating system and/or your hardware processor.
    The sapjcorfc library, the rfccm | librfc32 library or both require a higher operating system version.

    My guess is it's either a corrupt cookie or you have some add-on blocking cookies.

    If you have the EM (Enterprise Manager) installed on your stand alone WLS (which you should) you can select the managed server your app is running on, select the 'Log Configuration' menu and you should see almost the same representation an in jdev.

    Go to the Network tab.. and go to network options on the bottom of that page.
    Enable Default Host.. is DMZ..
    Tick the box and type in the IP of the computer or device you are placing in the DMZ.

    I have found that by quiting the finder, the network becomes enabled. Does anyone know how the network can be enabled at start up?

    When I try to log in to iCloud I get a message that my Apple ID is valid but not an iCloud account.How do I log in?

    Hi reswaikiki,
    Usually if it says your Apple ID is not an iCloud account, that means you have not yet enabled your Apple ID as an iCloud account.  So you did set it up correctly on your iPod touch?
    If not yet, please see Set up iCloud on all your devices.

  • How to restrict logging on portal (Performance issue)

    Hi guys,
    does anyone know how to restrict logging of the portal? Even though I made a change on Visual Administrator -> Services -> Log Configurator setting ALL categories to severity = 'Error', I keep getting 'Info' severity traces logged in defaultTrace.trc (viewed by Logg Viewer). Which in practise means tons of logged trace information! I think this might be one of the reasons we have been experiencing performance issues lately.
    Does anyone know how to restrict this logging?
    Any help greatly appreciated!
    Cheers,
    Frank

    Hi,
    I would not only set the severity of categories to 'Error' but also locations to 'Error'.
    A log controller - can be a "category" or a "location".     Categories are used for "logging" and represent problem areas such as network, database, security, user interface, etc. Identified by a slash-separated ('/') path of names, prefixed with an additional slash.     Locations are used for "tracing" and correspond to places in the development components. Identified by a dot-separated ('.') path of names, which is often the name of the respective java package.
