Rsync via ssh doesn't work anymore since Core 170

The backup has always run smoothly in recent years.
Since Core 170 I get the following error (aborting):

rsync -az --delete /mnt/backup/backup/
ERROR: rejecting unrequested file-list name: lib
rsync error: protocol incompatibility (code 2) at flist.c(998) [Receiver=3.2.4]

What could cause this termination?

Greetings Fritz

maybe this bug: rsync v3.2.5 rejecting unrequested file-list name · Issue #356 · WayneD/rsync · GitHub

fixed in rsync 3.2.6. Hopefully IPFire can update to this version as well. core update 170 has not being having the best of luck.

Thanks for your answer!
Do you plan to include the rsync update in Pakfire?


That bug is from v3.2.5 but IPFire is currently running with v3.2.4 which was installed in April 2022. No update was done of the rsync package itself but a patch was added to fix a CVE with rsync. I can’t tell if that might have introduced a difference.

Searching on the

error message I found many reports about differences in rync version between machines causing this error message over several years and many version numbers.

Has there been an rsync version update on the other machine. One thing that can be done is to tell rsync on the other machine to use the protocol from version 3.2.4. man rsync should help with that.

I will do a patch to submit an updated version but that will likely not make it into CU171 as that was planned to be closed by end of today and the Testing release issued by the end of this week but it should get into CU172

I built rsync version 3.2.6 and found it to be working with core 170, haven’t looked that far into it other then that.

Version 3.2.4 (unchanged) is running on the other computer.
I will update rsync to version 3.2.6 and see if it works.

which git version should I use to build?
Can you send me a link?

Thanks for the help!

I have found a bug report in rsync about the CVE-2022-29154 patch giving the error message that you found.
CVE-2022-29154 was a high severity issue and so was applied but no there was no feedback, positive or negative, on rsync from the CU170 Testing Release.

rsync fixed the bug in their git repository but that fix was flagged and fixed five days after the CVE patch was merged into the IPFire next tree.

The updated CVE fix is in version 3.2.5 and 3.2.6

The updated CVE fix is in version 3.2.5 and 3.2.6
How can I use it? I only have version -3.2.4-15 in Packfire.

The only options available are

  • Wait for the updated version to be included and released. I am currently doing the build of 3.2.6 and will submit the patch later today. I will flag up that this is an important fix to deal with a non-working rsync in CU170. Hopefully my arguments will result in it getting squeezed into CU171 at the last minute but I can’t guarantee that in which case it will be in CU172
  • Build the new version of rsync yourself -

Unfortunately you can’t revert back to an earlier version of the rsync addon as the IPFire addon server always only has the latest released version.


I have raised a bug for this, so that it is recorded.

A patch for version 3.2.6 has been built and submitted to the IPFire Dev mailing list and to Patchwork.


Thank you for your quick feedback!

Ok then I will try to build it myself and wait.

Many greetings

It has been agreed that my patch with rsync-3.2.6 will be merged into CU171 which should end up going to Testing at the end of this week (no guarantees though).

It would be good if it would be possible for you to upgrade to the Testing release of CU171 to confirm that it resolves the problem for you. Based on all the info in the rsync git repo I expect it too but it would be good to confirm it.


Yes I am now on testing and waiting for the update.
I can still build my own…
can i get back to stable? better ask.

If you have changed from stable to testing but not then run the update you can still change back to stable. Once you have run the update the easiest way to go back is to take a backup and do a fresh install.

The rsync-3.2.6 patch has been merged into CU171.

Luckily I asked again. It kind of reminds me of before. I don’t want to do that! =))
I will build it myself.

If I reinstall and then restore the backup, will ALL settings including firewall rules be restored?
I would give it a try just to try it.
I still have a full backup.


Yes, they will. There is also a file /var/ipfire/backup/include.user that you can add additional directories or files to that will then be backed up. So if you have created scripts, or results files etc then you can add them to that file to be backed up in the IPFire backup files. The entries in include.user should have the leading / removed.

The .ipf backup file is just an archive file so you can open it up and read what is in it using a GUI or command line tool. Then you can see all the files that have been saved and can look at their contents.


My backup .ipf files have been very small since July 17th, 2022, and I cannot open them either.
What GUI or command line tool can I use to read the .ipf backup files?


I can’t read(open) you

The additional files must be included in the “/var/ipfire/backup/include.user” like this?


I use xarchiver, it’s a gui app on Linux.

My sizes are all correct but I have just noticed when opening some of mine up that the content does not look right. My user defined content is missing from the file but also not all the standard data is showing up in it.

Incidentally if you use xarchiver on a 1.5GB file then it will take some time before you see the gui screen and some time before it is fully opened. My files are around 500MB and they were taking around 20 to 30 secs.

I am going to have look further at this issue with the backups. Obviously haven’t looked at them for a while. Will try a command line test.

Panic over. The backup files are okay but xarchiver is having problems properly opening them. This includes ones that have opened properly in the past so obviously a bug has occurred in xarchiver.

On the command line use tar tvzpf 2022-10-01-21_00.ipf replacing the IPFire backup file name I have written with the one you want to look at. This is basically the command that IPFire would use (minus the exclude files) but with a t in place of an x so that you only get shown what the contents are without them actually being extracted.


If you want to look at the .ipf archive file with a Linux GUI then lxqt-archiver will correctly show it if you change the extension from .ipf to .tar
lxqt refuses to try and open the file if it has .ipf but changing it to .tar works fine and the content is as it should be. Then after viewing the contents you would need to change the ext back to .ipf

deepin-compressor is a Linux archive manager gui that I have found that works properly with the IPFire backup files while still leaving the extension as .ipf

Cool that works perfectly and my additional folders and files are also included.
