Hello, That is error message i find in _TOPDIR_/pc/$host/LOG file. I'm using rsyncd as xfer method to backup $host which is a linux machine. Please what can be the causes of this error? Hear i put rsyncd.conf's file: -------------------------- [backup] path=/home read only=no use chroot=yes pid file=/var/run/rsyncd.pid secrets file=/etc/rsyncd.secrets uid=0 gid=0 strict modes=yes hosts allow=192.168.10.5 "Ip address of server" ignore errors=yes ----------------------------------------------------- --------------------------------- Appel audio GRATUIT partout dans le monde avec le nouveau Yahoo!

Hi, I seem to be having an issue with backing up a client via rsync. The client is a VMware ESX host (modified RedHat install). I have browsed all the archives I can find and followed them as best I can. If I issue the following command from the backuppc server ssh -l root 10.10.137.231 whoami from either the root account or the backuppc account I get a reply of=20 root=20 without having to enter anything (ie/. Does not prompt for a password or to accept a key). From the backuppc server I have also entered: su - backuppc -s /bin/bash and then I try and run the backup manually to see what happens here is the command I have used: /usr/share/backuppc/bin/BackupPC_dump -v -f mnfsbvm1 and I get the following: cmdSystemOrEval: about to system /bin/ping -c 1 mnfsbvm1 cmdSystemOrEval: finished: got output PING mnfsbvm1 (10.10.137.231) 56(84) bytes of data. 64 bytes from mnfsbvm1 (10.10.137.231): icmp_seq=3D1 ttl=3D255 = time=3D1.14 ms --- mnfsbvm1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev =3D 1.148/1.148/1.148/0.000 ms cmdSystemOrEval: about to system /bin/ping -c 1 mnfsbvm1 cmdSystemOrEval: finished: got output PING mnfsbvm1 (10.10.137.231) 56(84) bytes of data. 64 bytes from mnfsbvm1 (10.10.137.231): icmp_seq=3D1 ttl=3D255 = time=3D1.18 ms --- mnfsbvm1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev =3D 1.186/1.186/1.186/0.000 ms CheckHostAlive: returning 1.18 started full dump, share=3Dvmconfigs Connected to mnfsbvm1:873, remote version 26 Connected to module vmconfigs Sending args: --server --sender --numeric-ids --perms --owner --group --devices --links --times --block-size=3D2048 --recursive --checksum-seed=3D32761 --include=3D/ --ignore-times . .

It is likely the way you set up the client key. Here are my notes to setup a client key. This "Unable to read 4 bytes" also drove me crazy. In this case BackupPC user is apache. Setting Up SSH for Rsync for Linux Clients. To use SSH you must create a certificate on the BackupPC Server and copy it to the Linux Client machine. SSH Files: ssh config file: /etc/ssh/sshd_config ssh logs: /var/log/secure You will need this ftp program so: yum install ncftp You will need this Perl module on the client: cpan cpan> install File::RsyncP Then exit cpan: cpan> exit On the BackupPC Server create a login shell for the BACKUPPCUSER which in this case apache. You will also have create a directory for the certificate: Log in as root: mkdir /var/www/.ssh chsh apache Changing shell for apache. /bin/bash Login as apache and create a certificate: su apache ssh-keygen -t dsa Generating public/private dsa key pair. Accept the defaults, enter return for all questions - enter nothing for the pass phrase so the results are: Generating public/private dsa key pair. Enter file in which to save the key (/var/www/.ssh/id_dsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /var/www/.ssh/id_dsa. Your public key has been saved in /var/www/.ssh/id_dsa.pub. The key fingerprint is: 14:ef:71:5c:s7:5e:d0:ed:9a:b9:21:89:7a:e1:e7:f1 ap...@ba... XXX.XXX.XXX.238 scp /var/www/.ssh/id_dsa.pub XXX.XXX.XXX.238:/root/.ssh/authorized_keys2 Now login as root and copy the key to the linux client: su root Password: Copy the key to the Linux Client computer, in this case the ip address is XXX.XXX.XXX.XXX. scp /var/www/.ssh/id_dsa.pub XXX.XXX.XXX.XXX:/root/.ssh/authorized_keys2 The authenticity of host '10.0.0.100 (10.0.0.100)' can't be established. RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'XXX.XXX.XXX.XXX' (RSA) to the list of known hosts. root@XXX.XXX.XXX.XXX's password: id_dsa.pub 100% 606 0.0KB/s 00:00 Then exit: exit XXX.XXX.XXX.238 ssh -l root XXX.XXX.XXX.238 whoami Now test the login, eventually you should get just root with no password required: ssh -l root XXX.XXX.XXX.231 whoami Results: root Then exit: exit > Hi, > > I seem to be having an issue with backing up a client via rsync.

That means, i am doing localhost backup using rsync over ssh. ssh -l root myhost.mydomain whoami gives root ssh -l root localhost whoami gives root Key is in place in /etc/ssh/ssh_known_hosts.

If you can't log in without a password then neither will BackupPC. You need to set things up, probably with passphraseless ssh keys, such that the backuppc user on your backup server can log into the client without giving a password. hth, Keith |

It is reported on the mail list fairly often, but usually turns out to be that the ssh keys were set up and tested as the root user on the backuppc server instead of the backuppc user, connecting as root to the target.

After the last command, ssh-copy-id -i .ssh/id_dsa.pub ro...@ma... I receive - No identities found. Thank you for your help.

It's rsa, instead of DSA. Is that the possible issue? ~/.ssh# has 3 files: Id_rsa id_rsa.pub known_hosts So instead of ssh-copy-id -i .ssh/id_dsa.pub ro...@ma...<mailto:ro...@ma...> I would enter ssh-copy-id -i .ssh/id_rsa.pub ro...@ma...<mailto:ro...@ma...> ?

Devils in the details. Now it returns 'ssh: Could not resolve host name .ssh/id_rsa.pub: Name or service not known I've altered the syntax as: Ssh-copy-id .ssh/id_rsa.pub root@server Have I missed the syntax somehow?

Interesting. The command syntax worked, (Thanks Les) But it returned: Permanently added 'rsa.pub' (RSA) to the list of known hosts.

I'm SSH'ing into each server and in turn SSH'ing into each server that is having a backup issue to determine if they can connect. Some can, some can't. 'Strict checking' is currently enabled and I am getting a . If I simply disabled 'strict checking' and determined that all systems could Resolve new keys amongst themselves, then enable 'strict checking' again, would this be an acceptable troubleshooting step to determine Why Linux boxes can't backup? The concept is a pull configuration, correct? The BUPC server requests the data from each server, But the keys have been renewed and need to be generated again. What I don't know is the process for basically starting over with the SSH keys.
