Re: [BackupPC-users] How to run a manual backup.
Thanks, Les and Iosif for the headsup on that link. It explained the problem OK. So my plan now is rather than changing the crypto used, is to convert my small home network to use ECDSA keys over the weekend. Hope things go Ok.

Re: [BackupPC-users] How to run a manual backup.
Thanks, yes the real problem is with the configuration of sshd on CS-9. It seems to be slightly different than on CS-8. So I don't have ssh working on the CS-9 box yet. I get the following error when I try to ssh between accounts even on the laptop box itself. sshd[2608]: refusing RSA key: Invalid key length [preauth] sshd[2608]: Accepted password for root from 192.168.1.8 port 35958 ssh2 So I was hoping for the test of BackupPC that running a manual backup when the ssh login failed that it would fall back and ask for a password. This is just a test laptop and I wanted to make sure all the services I regularly use were working on it before I upgraded my home network. So it's back to sorting out sshd. Have a look for that on https://serverfault.com/questions/1095898/how-can-i-use-a-legacy-ssh-rsa-key-on-centos-9-stream Maybe it helps.

It looks like they have changed the acceptable key pairs for sshd in CS-9. I found this article saying you either have to configure the crypto policy to accept SHA1 or generate new key pairs with an acceptable format. https://serverfault.com/questions/1095898/how-can-i-use-a-legacy-ssh-rsa-key-on-centos-9-stream -- Les Mikesell lesmikes...@gmail.com ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
Re: [BackupPC-users] How to run a manual backup.
Thanks, yes the real problem is with the configuration of sshd on CS-9. It seems to be slightly different than on CS-8. So I don't have ssh working on the CS-9 box yet. I get the following error when I try to ssh between accounts even on the laptop box itself. sshd[2608]: refusing RSA key: Invalid key length [preauth] sshd[2608]: Accepted password for root from 192.168.1.8 port 35958 ssh2 So I was hoping for the test of BackupPC that running a manual backup when the ssh login failed that it would fall back and ask for a password. This is just a test laptop and I wanted to make sure all the services I regularly use were working on it before I upgraded my home network. So it's back to sorting out sshd.

Re: [BackupPC-users] How to run a manual backup.
Hi Tony, If you're stuck at the ssh part, you won't be successful running a backup as making the connection is the first step. What happens when you try to ssh to this client from the backuppc account on the backup server? Assume you've already tried ssh-copy-id but it's failing. I'm having trouble imagining what part of an upgrade would have broken a functional ssh key pairing unless the IP address changed. As for a local backup you could use rsync to copy home to another partition: rsync -a dir1/ dir2 https://www.digitalocean.com/community/tutorials/how-to-use-rsync-to-sync-local-and-remote-directories From: Tony Molloy Sent: Sunday, March 3, 2024 9:42 AM To: backuppc-users@lists.sourceforge.net ; Tony Molloy Subject: [BackupPC-users] How to run a manual backup. Is it possible to run a backup of a share from the command line. I've checked the manual and can't seem to find it. I've several CentOS-Stream-8 boxes backing up without problems.
