Re: Fwd: rsync and unlink permission

Is there any solution to this problem? This depends on OS, filesystem and mount options. I'm guessing (read the headers) you're running Linux (debian) so this should work for you just fine. I also assume that foo is a member of the www-data group. chmod +t,g+ws /var/www The perms in ls -l should now read drwxrwsr-t. At this point foo and other memebers of the www-data group can create and delete their own files in /var/www. You are correct that write permission is needed to create, rename, and remove links in a directory. Therefore you need to grant write permission. The sticky bit on the directory (t) means that only the file owner can unlink or rename a file therein. The file owner will still have to have write permission on the directory. /tmp should always have the sticky bit on. Setting sgid (the s in drwxrwsr-t on the directory will cause any files and directories created there to have gid=www-data and the sgid will propigate to the subdirectories created. This way even if they put a file there with 640 perms the web server (if in www-data) will still be able to serve the pages. rsync may override the mode and group ownership but if you want to grant multiple people write access sgid helps. A filesystem mounted with BSD semantics will behave this way even without sgid set. PS. A web tree doesn't belong in /var. /var is for log files, caches, and other temporary stuff. -- J.W.

Re:
Thanks for all the suggestions u gave... After reading your mail and the site address that u had given, i feel that there is NO WAY for installing Rsync as Service (as per the standards given by MS) as of now. I strongly support your proposal for rewriting Rsync for Windows Platforms (not necessarily for 98 or similar versions but for NT based platforms) in order to run the same as service or to have some module which can assist the same. Please let me know if i can be a contributor for the same (having in depth knowledge of Networking protocols and standards). Thanks Nitin Agarwal [EMAIL PROTECTED] wrote: Howdy... I guess I was clear enough before on the topic, as you had to stretch your mind to see the underlying problem, which I briefly touched upon. The basic problem is that you have an application that is not a Windows Service, but rather has been entered into the Windows registry through the utilities that you have used, such that it looks like a Windows service. Here is the URL for NT Services, which you may find helpful in developing a better understanding of what a service is in Windows: http://msdn.microsoft.com/library/default.asp?url="/library/en-us/vbcon/html/vbconCreatingNTServiceApplications.asp In this discussion, you will notice that it references the use of templates which reference the appropriate classes, namespaces, setting up the inheritence from the base class, and more automatically service applications. In your case, you appear to be using utilities that allows you to install an application into the Microsoft Services, but this does not make it a service, per se, as it does not conform to the standards by which Microsoft has specified for designing services for its platform. My proposal is to rewrite rsync for Windows 98, ME, NT, 2000, XP, and .NET, such that it conforms to the standards for a service under the Microsoft platform, as specified by Microsoft. I have all of the current platforms from Microsoft, excluding Windows 95, in addition to the support SDKs for each platform, in addition to Microsoft Visual Studio 6.0 Professional, Microsoft Visual Studio 6.0 Enterprise, and Microsoft Visual Studio .NET Enterprise Architect.
Re: Win32 Version? MODIFICATION NEEDED
Hi!! There is one programming consideration which need to be programmed in RSYNC for Windows.. PROBLEM Whenever Rsync is installed as service on Windows Platform, the rsync application gets terminated while logging off the server. POSSIBLE SOLUTION - An Event Handler should be added in Rsync for windows binaries.: following is the explanation for that: For WIN32 applications (i.e. Rsync): when the currently logged-in user is logging-off, all Console applications receive a CTRL_LOGOFF_EVENT event from the Console. If your Console application has registered a Console event handler (via SetConsoleCtrlHandler), it must ignore CTRL_LOGOFF_EVENT in order to survive the logoff. _ Can we expect some help on this regard?

Re: Win32 Version?
I dont think so.. because problem is not coming in service. In the service manager control box, rsync service is running, but problem comes only once i log off from the server. And as i mentioned in previous mails, the rsync.exe process is also terminated after i log off. This may be something to do with version... (i m using 2.1.1 and Bart told me that he is having no problems with version 2.5.5) Further i studied the problem, and concluded that this kind of problem always comes when the application is not using any Console event handler (via SetConsoleCtrlHandler) to ignore CTRL_LOGOFF_EVENT event. This problem could have been addressed in further releases.

Configuration
How do you restrict rsync transfers to only modules in the configuration file? It seems like even though I have a module configured, users can transfer files that they had permission to which is not under the directory of the module. EX. /etc/passwd...

Re: rsync with large gzip files.

In the 17GB When we refer to large file support it means files larger than 2GB. You mentioned about issues with mount options in AIX and large file problems with HPs. I was wondering if you could provide some background to such problems which would be contributing to such problems? Look in the archives. Also, would the larger blocksize eliminate such problems with the large g-zipped files, hence there would not be a need to have version 2.5.5? Your files aren't that large. A larger blocksize may improve performance and help avoid a completely unrelated issue. If you want help with a bug you will need to ugrade. Much of the time when a bug is encountered on older versions it has already been fixed. Upgrading is likely to cause the bug to disappear. If you do have a bug you would need to upgrade to current or CVS and build your own binaries in order to apply the fix. -- J.W.
