Re: [PLUG] rsync not working backuppc4
So you've set up a passwordless login for a user (im assuming username "eagle") and that works. But when you try doing it with backuppc it fails with the /nonexistent error. What this probably means is that backuppc is configured to perform backups as a user that you have not set up for passwordless login. Keep in mind that ssh keys are per user. this means that if I setup passwordless login (e.g. 'bkoenig') then it will only work for 'bkoenig'. If i try to log in as someone else (such as ssh ekoe...@remote.host ) it will fail because said keys are not visible to ekoenig. It sounds like you have set up passwordless login for root, but not for the user backuppc uses, and that particular user doesn't actually have a home directory, this throwing the error you saw when attempting to create a folder. Does BackupPC4 have a GUI configuration area or something that lets you tell it to use a specific user? This is a common theme throughout FreeNAS, you can set different services to run as different users, isolating the processes and allowing it to run with permissions on a per-service basis.

Re: [PLUG] BackupPC on FreeNAS 11.2 U7...
you haven't given a whole lot of information about how you are setting up your users, so I can't really answer your question What user is initiating the backup on centos? which user is saving the data on FreeNAS? What is the rsync command being deployed to initiate the file transfer? Also, you say that you just changed /nonexistent to /root, but where? Did you make this change on FreeNAS, through which interface? Or was it on CentOS? I can tell that you are running an rsync based backup application, but other than than i know pretty much nothing about your setup. The error message you gave was pretty straightforward, but without knowing which applications you have configured where, I don't know what the root cause of that error is.

[PLUG] rsync not working backuppc4
I followed instructions to allow passwordless rsync, but I still can't back CentOS 7 up. I do a terminal on my FreeNAS 11.2 U7 web interface: # iocage console backuppc And I'm root in the jail for BackupPC4. I can manually ssh to eagle without a password. What I cannot figure out is why the web interface for backuppc4 won't back anything up. I think it is an authentication issue, but why we have a nonexistent backuppc user is beyond me. ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Re: [PLUG] BackupPC on FreeNAS 11.2 U7...
SSH keys are *usually* stored in $HOME/.ssh, and the error you are seeing clearly indicates that this folder cannot be created. Since it cannot create the folder, it cannot store your public key, and therefore cannot authenticate via key pair. I'm fairly new to FreeNAS, but on my box /nonexistent/ literally does not exist. My understanding is that this is a keyword used for users that run without home directories. Which user are you attempting to use on the FreeNAS end? Whatever user it being used to read/write files on your NAS box appears to be configured to run without a $HOME folder, and will be unable to store a public key for authentication. This is is just a guess but if the BackupPC app runs as a given user, you may need to add a home folder for that user. Then you will be able to transfer your public key to it. -Ben On Sun, Nov 24, 2019 at 6:12 PM wrote: > This is the rsync child about to exec /usr/local/bin/rsync_bpc > Could not create directory '/nonexistent/.ssh'. > Host key verification failed. > rsync_bpc: connection unexpectedly closed (0 bytes received so far) > [Receiver] > Done: 0 errors, 0 filesExist, 0 sizeExist, 0 sizeExistComp, 0 filesTotal, > 0 sizeTotal, 0 filesNew, 0 sizeNew, 0 sizeNewComp, 2 inode > rsync error: error in rsync protocol data stream (code 12) at io.c(226) > [Receiver=3.1.2.1] > rsync_bpc exited with fatal status 12 (3072) (rsync error: error in rsync > protocol data stream (code 12) at io.c(226) [Receiver=3.1.2.1]) > Xfer PIDs are now > Got fatal error during xfer (No files dumped for share /) > Backup aborted (No files dumped for share /) > > November 24, 2019 7:59 PM, mich...@robinson-west.com wrote: > > > > https://www.ixsystems.com/community/threads/quickstart-guide-for-backuppc-4-in-a-jail-on-freenas.740 > > My question is, do I need to import the ssh key for root user on my CentOS > 7 box so I can rsync back up the entire system? > I'm trying to trigger a backup from my FreeNAS box using BackupPC4 in a > jail. > ___ > PLUG mailing list > PLUG@pdxlinux.org > http://lists.pdxlinux.org/mailman/listinfo/plug > ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
