A lot of companies are unsure which solution to choose and many may not be aware of Docker Swarm as an alternative to Kubernetes. One thing that many Sysadmins find is that Docker Swarm is simply easier, quicker to setup and maintain by far than Kubernetes.........

This is caused because the user is running as qemu for virt-resize and if qemu does not have privileges to read from the source and write to the destination, it will fail with the below. So either change the uid of qemu or change the ownership of the source and target. Solution: export LIBGUESTFS_BACKEND=direct virt-resize --expand /dev/sda2 /root/kvmtemplates/windows2019-eval-template.img /root/kvmguests/kvmkvmuser4515........

Symbolic link not allowed or link target not accessible: /path/httpdocs/news.html There are a few reasons that can cause this message and this is for people who have ruled out the basics, eg. your symlinks are enabled and the right permissions are applied (but read on to learn about ownership requirements above the directory in question). So there are a few key things here that cause Apache not to follow symlinks:........

If you just do a normal chown user.user somedir it won't work. You will see the ownership is still the previous owner. How To Change Ownership Of Symlink: The simplest part is just adding the -h which means no dereference so it applies the ownership on the symlink and does not try (and fail) to change ownership of the dereferenced symlink destination. chown -h user.user somedir........

First of all I got this error after accidentally messing up my usergroup by using usermod -G user group When I would login using SSHkeys it would fail: sshd[2020]: Authentication refused: bad ownership or modes for directory /home/one No worries, the fix is simple! chmod g-w /home/use........

Ihave a tar and when extracting it changes /root to a uid and gid of the source server which is bad especially for /root! You can get around this by extracting as follows: Add the -o switch which means "--no-same-owner" tar -o -zxvf sometar.tar.gz........

Ifigured out what caused this but don't have the solution just yet. Iwould deploy a certain script from a .tar.gz to some servers and found that /root was always owned by user and group "1000.1000". This corresonded to the user who made the .tar.gz. For some reason when extract normally with "tar -zxvf file.tar.gz" it impacts the parent directories ownership. There must be some recursion going on or possibly the .tar.gz but I haven't f........

This can be a case of bad permissions or modes as the error says. Normally one would assume permissions but often a script may change ownership of /root to something else. This was the case half the time I've encountered this. So in short make sure ownership is correct chown -R root.root /root........

In my case I could login with the initial install but I rsync'd everything over while preserving ownership and permissions to another RAID partition and booted from that.was fine before. The problem is that you are kicked out the second you login and the problem was SELINUX for some reason (perhaps it noticed something strange when it was moved to the new partition) login: pam_unix(login:session): session opened for user root by LOGIN(uid=0) login: ROOT LOG........

It is a permissions issue that is hard to fix. All but one USB device is greyed out. I am already a member of "vboxusers" I have already enabled and disabled USB support for the guest. I have already reinstalled the latest VBOx guest editions If running as root it all works fine Changing........

This happened after a customer migrated their hosting and the issue was being unable to access PHP sessions. Warning: session_start(): open(/var/lib/php/session/sess_3e0oms763m6mrqekdnnmodlhs3, O_RDWR) failed: Permission denied (13) in /register.php(202) : eval()'d code on line 1 Solution:(use the correct ownership/permissions) chown apache.apache -R /var/lib/php........

This happens because of a permissions or ownership issue. Generally /var/lib/mysql should be all owned by mysql.mysql (check that). To fix it use chown -R mysql.mysql /var/lib/mysql Also make sure the files are at least readable and writable by mysql (eg. 700).........

ntpd[7047]: can't open /var/lib/ntp/drift.TEMP: Permission denied chown ntp.ntp /var/lib/ntp/ The solution is shown above and changes the ownership to ntp.ntp which is what the ntpd daemon/server is running as. This is based on Centos but the same idea will apply on any other OS. You can do a "ps aux|grep ntpd" to see what it is running as in the case it's running as a different user. After that this annoying message wil........

JFolder::create: Could not create directory Plugin Install: Failed to create directory: This can occur when trying to upload content or when installing themes/templates. It's usually not a permissions issue per say but doing a 777 (which is very insecure) will fix it. But the real problem solution is that the owner of the files is different than the owner of the Apache process/server. Eg. if your Apache is running as user "apache........

*Make sure that the ownership is 501.501 or mobile.mobile when copying back (especially if using ssh or sftp as root on the iPhone) otherwise things will break. Eg. the contacts will be blank even after trying to update due to incorrect ownership/permissions. iPhone Notes Location/Restore: /private/var/mobile/Library/AddressBook AddressBookImages.sqlitedb AddressBook.sqlitedb Once you restore the contacts and restar........

sshd[9217]: Authentication refused: bad ownership or modes for file /root/.ssh/authorized_keys I made sure the entire .ssh subdir is owned by the user root (this is root's account); chown -R root.root .ssh chmod 600 .ssh/authorized_keys but it still doesn't work and gives me the same message sshd[7339]: Authentication refused: bad ownership or modes for directory /root chmod 700 /root........

One of the purposes of rsync is to backup whole filesystems and archive them but how can you do that properly and restore things to normal if all permissions and ownerships are not preserved from your root filesystem? It's not desirable to have everything running as root, especially not just for an rsync. The Easy rsync preserve permission solution for non-root users sudo is the answer and all you have to do is edit /etc/sudoers At the end o........

Not sure what rsync switches/options to use? rsync -PDrphogtl The short version would be: rsync -Pha I think these are really common sense options to use and probaby should be the default. Explanation of rsync switches P = display the progress D = hybrid of --specials and --devices so all special and device files will be copied as well. r = recursive (otherwise rsync won't copy files deeper than........
