error: XSIDiff error, details: rekeyed outbound cipher

I manually started a backup-job (rsync over ip), only one VM.
The system found the license-key for XSIDiff 1.1.1.4 on both machines.

It looks like, that the job automaticly switched to use the XSIDiff instead of "pure" rsync.
In the report e-mail I get the following error code (in app. 200 lines)

ERROR CLXSIDF1, details: [WSE2016] error: XSIDiff error, details: rekeyed outbound cipher rekeyed inbound cipher

both machines use:
VMware ESXi 6.7.0 build-13981272
XSIBACKUP-PRO 11.2.7

it worked fine with:
XSIBACKUP-PRO 11.2.3
VMware ESXi 6.7.0 build-10302608

A RAID Controller (DELL PERC H310) was added on both systems

What can I do?

Re: error: XSIDiff error, details: rekeyed outbound cipher

That is an OpenSSH error that has to do with the SSH tunnel keying

Contact support, there's always a chance that it's a combination of OpenSSH versions that causes it but it looks more like some issue with your job.

Re: error: XSIDiff error, details: rekeyed outbound cipher

I have the same problem using XSIBACKUP-PRO 11.2.10 in XSI6.7.0 Update 2 (Build 13006603):

ERROR CLXSIDF1, details: [Active Directory] error: XSIDiff error, details: rekeyed outbound cipher rekeyed inbound cipher

How to solve this? Thanks.

Re: error: XSIDiff error, details: rekeyed outbound cipher

That is just an informational message from part of the SSH tunnel.
- Is it affecting your backups?, apart from the error itself, which should be thrown as a mere warning, probably not even that. We will fix this ASAP.
- Is your VM big, does it take a lot of time for the backup to complete?

Re: error: XSIDiff error, details: rekeyed outbound cipher

the backup was interrupted in the middle of the VM file and did not finish, it appends not all the VM, only 2 of 4 has this error.

Re: error: XSIDiff error, details: rekeyed outbound cipher

Update to latest version 11.2.19, that will help the issue.

Re: error: XSIDiff error, details: rekeyed outbound cipher

But do you know the reason?

Re: error: XSIDiff error, details: rekeyed outbound cipher

Well, given the fact that we launched a fix, it'd be difficult to achieve the fix by chance.
Yes, of course we know: the OpenSSH binary has become extremely verbose in latest versions printing to STDOUT irrelevant information such as rekeying, FIPS mode on, etc.... We don't know why OpenSSH development responsibles have decided to do so or whether it is some unintentional pseudobug or some wicked approach.

We have fixed it by intercepting irrelevant information in the SSH tunnel and ignoring it. Messages to be ignored are kept in the [b]conf/err-imsgs[/b] file.
