Hello List! I got a small (50mbits or so) application layer ddos attack against a few name servers (thousands of IPs sending lots of bogus A record requests - weird) - one of the name servers was behind a shorewall firewall. That firewall was running a 2.6.18-194.11.1.el5 kernel and shorewall-4.4.11.1-1. I noticed that the shorewall host had ksoftirqd using 100% of the CPU during the

Hi all- My test results so far indicate a pretty decent improvement in overall rsync performance when using a slightly more sophisticated checksum calculation. The attached patch has the required changes (in hindsight, I should have compressed this using zlib with the new algorithm :-) ). Some things to know about the patch: First, it is against the zlib library - NOT the gzip application. By

Greetings, I was curious if the 3.x glusterfs has made any significant write performance headway (especially when dealing with small files). Last time I was testing 2.x, I had to write glusterfs off due to poor performance (previous config/performance-stats can be accessed in list archives if curious). Did anyone notice *dramatic* improvement when switching to 3.x? Thanks, Michael

Hi, Is there a way in which rsync's -z compression (zlib) utility can be benchmarked? I'm trying to compare the compression ratio between rsync and external compression tools like gzip and bzip2. Are there any advantages to using rsync's internal compression mechanism specified with the -z option compared to solely applying external compression i.e. bzip2 to the files and invoking

Hello group, I'm having a very hard time rsyncing efficiently a MySQL database which contains very large binary blobs. (Actually, it's the database of Mantis bug tracker [http://www.mantisbt.org/], with file attachments stored directly in the table rows. I know it's a bad idea from many other reasons, but let's say it was given to me as such.) First, I was dumping the

Hi, all - I've been digging into the question of using rsync to sync up compressed data, and read with interest the conversations regarding the rsync friendly patch available for gzip (I belive Rusty provided this patch). For anyone interested, the message thread is archived at http://lists.samba.org/archive/rsync/2002-June/thread.html. The broad outline of this approach were mentioned in

Hi, Recently We've upgraded some KVM hosts from Fedora 29 to Fedora 30 and now experience broken VM configurations on filesystem after virsh blockcommit. Commands "virsh dumpxml ..." and "virsh dumpxml --inactive ..." is showing diffrent configuration than the one on filesystem. In case of restart libvirtd or system reboot, there are broken VM xml configurations on

I noticed with rsync and compressed files or package files the transfer efficiency drops considerably. Eg. rsync an ISO image of a distribution will give you between 30% and 60% of the original transfer although from Beta1-Beta2 the change could not have been that great. The same thing happens with ZIP files for obvious reasons. My question or feature request if you want to call it is. Is it

Dear guru's Hopefully someone can shed some light in my issue. I have created a queue with a ringall strategy and all works fine. I want a caller to be able to exit the queue so they can leave a message. I've added the H option in queue command so callers can press * to exit. So far all well, on the cli there is a message the caller pressed * and the extensions stops ringing. But

Hi All, I have a 1.8GB PST file that is backed up every night from a cygwin install) and every night rsync transfers about 1.8GB of data for that file. It changes a bit, but for all intents and purposes the entire file is transferred. There are other files on this system that rsync more typically, so I'm fairly certain this isn't a switch or command error on the calling end. I have also

Hi I'm having issues sendig a lot of tar.gz backup files to a ZFS remote filesystem server. This files are compressed with the --rsyncable option. Sending without --inplace option rsync works well and send only the differences, but to create a temporary file and rewrite the file destination, zfs snapshots contain the full size of the backup, not only differences block. I've tried

Hi, while implementing the rsync protocol in one of our projects I found that the current CVS version still has a MD4 bug. I'm using the FreeBSD libmd implementation and I still had checksum mismatches with protocol version 27 for files whose size was a multiple of 64 - 4 ( - 4 due to checksum_seed). A patch for todays CVS version is attached. Someone should also review the clean_fname()

Hi all, I'm sorry if this is off topic here. I'll send this one anyways, but do let me know if you are interested in related project's release announcements so that I don't spam this list unnecessarily in the future. rsyncrypto is a utility that encrypts file in a rsync friendly way. Small changes to the plain text file will result in small changes to the cypher text file.

Hi, I tried performing a complete copy of 17GB of filesystems over the WAN (0.8GB/hr) with the speed of 16Mbps. The filesystem consists of several large g-zipped files. These large g-zipped files have actually been zipped out of other sub-filesystems and directories. I noticed that while transferring a lists of large g-zipped files, rsync tends to take a much longer time to transfer those files

Mike, As it stands right now, we use xz for our compression, so if rsync had a similar option for xz that would probably be an improvement. However, I think being able to decompress directly to the remote system would save more; elsewise I don't see how I'm going to be able to avoid untarring and uncompressing the whole xz file on the other end. thanks much, ed On Tue, Dec 6, 2016 at

Hello folks! I've been thinking about adding the capability to store files compressed and/or encrypted on either side of the rsync transfer. Let's say there's a storage space provider. I want to store my files on that server compressed (so I don't use more paid space than I need), and encrypted (so they can't read my data). I don't know much about encryption, but I

Hi, all. This is my first post to the list, so please forgive me if this is an old issue. I scoured the mailing list archives by hand and could find no mention of it, and the official FAQ-o-matic mentions it, but doesn't offer a fix that works for me. I've set up an rsync daemon on Windows NT4 by installing the latest cygwin. Using the cygwin1.dll and rsync.exe, I'm able to connect
