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/
