Hi, I am fairly new to DTrace, and wanted to ask something regarding synchronization objects. I have a multithreaded C++ program in which I use semaphores (POSIX version) for synchronization. I was interested in using DTrace to figure out the total time for which each thread in my application sleeps, blocked on a semaphore, i.e., as a result of sem_wait() call. In order to measure this, I

Hi, I have set a Samba AD DC on my network. Version is 4.1.17 on a Debian Wheezy. I have an issue on my Windows XP SP3 clients : the time on these computers is not synchronized with my Domain Controler. Big problem is, if time difference is considerable (more or less 5 minutes), users can not log in. On the other hand, my server is correctly synchronized with NTP server. I don't understand the reason of my problem, and don't know were to start investigating. H...

Hello to all I'm using asterisk 1.4 and dahdi. I had everything working fine, and I could place calls through my R2 channel. But now the channel is always "RED" and Im getting this error message: TE4XXP: Version Synchronization Error! Here is my chan_dahdi.conf------------------------------ [channels] language=en context=incomingr2 signalling=mfcr2 mfcr2_variant=ar

I'm trying to have my Samba 4 AD DC users mapped and synchronized with google apps for education accounts. I would like to start from the native windows password update procedure to eventually update the google apps password (actually, I think only some types of hashes are stored). Google actually provides a tool to synchronize user accounts and profiles which w...

...ormal Priority: P5 Component: core Assignee: wayned at samba.org Reporter: sbehuret at gmail.com QA Contact: rsync-qa at samba.org Files that have identical sizes and change times on the sending and receiving sides, but different contents, will not be synchronized by default (e.g. rsync -a --delete source:/path/ dest:/path/). Synchronizing these files requires the use of --checksum or --ignore-times options, which are both sub-optimal in most cases (see caveats below). I would like to propose new options to efficiently synchronize these files. To make this...

Hi, I am seeing constant "Log synchronization error"s in my logs. See later for an example. This is dovecot 2.2.4, pigeonhole 0.4.1, and postfix 2.10.1 (with mailbox_command = /usr/libexec/dovecot/deliver) on a Fedora 19 system. I am using packages from Atrpms so there are some patches applied - ask for details. The mailboxes have resently been moved from a i386 system. I have

Hi folks I face a problem about the data synchronization when using the ctdb. When one ctdb node fails, other ctdb nodes may not recover the data of the failed node. I think it may be due to the fact that ctdb stores its tdb files in the local storage. So, is it fine to store the tdb files in the shared directory of the backend storage? When one node fails, other nodes may recover the data from

As mentioned in below link:- https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller I am trying to synchronize time for Kerberos with NTP. But NTP(4.2.6) supported on hpux is not build with enabled signed ntp support *(**--enable-ntp-signd)* for time synchronization mechanism. What would be the impact if i don’t configuring time synchronization for Samba

2 questions regarding the synchronization of these events. 1) is onSuccess called before onComplete ( I assume it is) 2) if called after, is onComplete called after the onSuccess method has completed or are you at the mercy of synchronization issues? Hopefully someone can enlighten me. I tried reading the Prototype.js but couldn''t seem to determine this on my own.

... does not work. I use the W2k functionality "synchronize" on my laptop to have up2date synchronized copies of my files both at the laptop and the file server. The file server is a P 200 MHz running RH Linux 9. When on-line the synchronization of files works, except for my swedish letters "???". However when off-line working with my files, then reconnecting to the network and issuing...

Thanks very much, Volker. I want to synchronize three tdb files(listed as below) which is relevant to the opened file: 1) brlock.tdb 2) locking.tdb 3) smbXsrv_open_global.tdb These three tdb files are used to realize the durable file handle feature. As what you have said, the performance will be affected if storing these three files in the shared storage. So can I realize the synchronization
