Trying to add this as a client generated the error 'Sorry, couldn't add backuo client, error 560 (invalid private/public key)'.Īny advice very welcome - I cannot find a way to update the client information, but would like to continue using it with my original backup set. In the advanced tab, Retrospect client version was correctly shown as 7.7.106 and ip address was correct. Checking the Configure Client properties, version was recorded as 7.6.106 and ip address was incorrect. On installing the 7.7 client on a second client laptop which had origianlly used my other client licence, I was unable to back up the laptop, because Retrospect could not find it. Having migrated form an XP Pro SP3 machine and copied over the Config75.dat file, I was able to install the 7.7 client licence on the original host PC and run a partly successful backup (though the client hard disk was failing). You can now access the NAS device from Retrospect as described in Working with Clients. When your system has booted back up you’ll be able to use the new root password.Running Retrospect 7.7 Pro on Windows 7.7 Ultimate 64. Make sure to remember your password, then restart the NAS device. Once the reboot has completed you will be able to use the root account with your newly set password.Īs shown we can reset the root password in Linux CentOS/RHEL 7 by booting with the ‘rd.break’ option, remounting the file system with read/write privileges, creating a chroot jail, executing the passwd command and then finally fixing up SELinux contexts.Īfter exiting the chroot and the initramfs root shell prompt the file system will be relabelled which may take a few minutes or more depending on the number of files you have. Enter the ‘exit’ command twice, the first one will exit the chroot jail environment while the second will exit the initramfs root shell and reboot the system.For a plain vanilla CentOS 7 server, it takes me about 2 minutes to complete. Note that this may take some time depending on the amount of files you have on the file system. Create the /.autorelabel command using ‘touch’.Ĭreating this file will automatically perform a relabel of all files on next boot. As SELinux is not running in this mode the file is created with no SELinux contexts, which can cause problems when we reboot. This is because when the ‘passwd’ command is run, it creates a new /etc/shadow file. If you’re not using SELinux, you could reboot at this point and everything would be fine, however by default CentOS/RHEL 7 use SELinux in enforcing mode, so we need to fix the context of the /etc/shadow file.From here the root password can be reset with the ‘passwd’ command.This is done by running ‘chroot /sysroot’. This is required so that any further commands we run will be in regards to /sysroot. Once the file system has been remounted, change into a chroot jail so that /sysroot is used as the root of the file system.This is done with the ‘mount -o remount,rw /sysroot’ command. At this stage, the root file system is mounted in read only mode to /sysroot and must be remounted with read/write (rw) permissions in order for us to actually make any changes.This will boot to the initramfs prompt with a root shell. Press “Ctrl+x” to boot with these options.Enter ‘rd.break’ without quotes at the end of this line, as shown below.
