I think you’re having a misunderstanding of the rsync algorithm and how the tool should be applied. Rsync’s performance advantage comes from doing delta transfers– that is, moving only the changed bits in a file. In order to determine the changed bits, the file has to be read by the source and destination hosts and … Read more
This really piqued my interest. I was able to replicate your findings in my lab with the same pattern of results that you describe. I used Procmon to to try to see what changes are made and almost gave up until I saw the following: That shows lsass.exe (Local Security Authority) writing to the local … Read more
It should be fine. Windows Explorer does a fine job of displaying filename case correctly. I use this in my smb.conf to make sure what I type in Explorer is what Samba uses (I set all of these per-share): case sensitive = True default case = lower preserve case = yes short preserve case = … Read more
the below steps have helped me resolve this exact issue on a number of occasions: Login to the samba server. Run a “smbstatus”. Find the pid of the process that has the lock on the file in the third section of the output. Verify that it matches the expected user and hostname in the first … Read more
I did find a way to do this. Hopefully this helps someone else looking for the same information. On the server, open a powershell then enter this command: Get-SmbSession | Select-Object -Property ClientComputerName,ClientUserName,Dialect For more verbose output: Get-SmbSession | Select-Object -Property *
This is an oldie, but considering it’s unanswered and I was looking into IPC$ and Samba, I will give it a try for the sake of documentation. Why would smbd not clean up IPC$ shares? As stated above in the comments to your question, the service is used for remote administration and communication among servers, … Read more
Do you have a password set in Samba (not in the system passwd file) for root ? You should be able to set such a password by running smbpasswd -a root.

NFS: it has a partial support for sparse file. Basically, it supports creating a sparse file but, when reading, the file is expanded to include zeroes. This means that, while you can create a sparse file via NFS, when reading back that very same file the in-transit network data will include any zeroes found on … Read more
SMB is a file sharing protocol and, as such, it is sometime left open to the internet for, well, sharing files. However, this is a very bad idea. Compared to simpler protocol as FTP or WebDAV, which basically have very small GET/PUT interfaces and are entirely implemented in isolated userspace processes, SMB is a much … Read more
