In this example, all emails whose sender is a@bc.com are deleted from the queue.
postqueue -j | jq -r ‘select(.sender == “a@bc.com”) | .queue_id’ | xargs -I {} postsuper -d {}
jq must be installed ( apt install jq )
for other filtering criteria
postqueue -j | jq
You can type and see the fields in the json output.
As a new feature,Plesk picked up zstd compression method for backups.If you want to create backup files with classic method you can edit the panel.ini file in two way
1. Go to Extensions ->Install and activate panel editor extension and open the editor in my extensions section
Select the editor and add these;
[pmm]
compressionMethod = deflate
2.Login to shell.Open /usr/local/psa/admin/conf/panel.ini file with your favorite editor like nano or vi.Add theses line to the appropriate place
[pmm]
compressionMethod = deflate
Note.You may already see [pmm] section.In this case you just add compressionMethod = deflate
below the [pmm] section.
A memory corruption vulnerability (CVE-2021-4034) in PolKit, a component used in major Linux distributions and some Unix-like operating systems, can be easily exploited by local unprivileged users to gain full root privileges.
Patch for Ubuntu is Available
https://ubuntu.com/security/notices/USN-5252-1
If you don’t have any patch please remove suid bit from pxexec tool with this command
chmod 0755 /usr/bin/pkexec
If you use debian or ubuntu,you should install the package first.
apt-get install curlftpfs
After the installation,create a folder where will you mount to.for example /mnt/rftp
sudo mkdir /mnt/rftp
curlftp’s format and its parameters are simple.for example,we have an ftp account like olriss and password: 123x4P at 192.168.1.199
in local server,mount remote ftp with using this command
curlftpfs olriss:123x4P@192.168.1.199 /mnt/rftp/
curlftps is similar to nfs tools so you can review the mounted ftp area in your mounted drive list.so check it with “mount -a” command.
after your work is finished,you can unmount it with similar way as nfs unmounting.You won’t need all parameters to unmount,You just unmount the folder like below,
umount /mnt/rftp
On Vmware Esx server,You can increase size of your virtual hard disk easily.If you use lvm for your guest os,you will need to add new virtual hard disk or just increase the size of your current disk.This guide will help you to extend size of the disk after you resize of your virtual disk by using vsphere
After increased the size on ESX ,In Linux Terminal;
rescanning the device.host id can change and it depents to your system.you must do that if you dont want to restart your guest;
echo “- – -” > /sys/class/scsi_host/host0/scan
see your disk and partitions;
fdisk -l
lets add new partitions.after you create the partition,you will need to set type of disk to 8e (LVM)
cfdisk /dev/sda (please note your new partition name sample :sda3
see your disk&partitions status again;
fdisk -l
check for available space;
df -h
scan for new partition
partprobe
create physical volume by using new partitions.(disk name may differ.)
pvcreate /dev/sda3
see your volume group and check and confirm
vgdisplay
extend your volume group
vgextend centos /dev/sda3
recheck;
pvscan
extend your logical volume with using the new part
lvextend /dev/centos/root /dev/sda3
in this point,last step may change according to your file system.if you use xfs ;
xfs_growfs /dev/centos/root
for ext4
resize2fs /dev/centos/root
finally see your new available space
df -h
For Centos Servers;
Please add these lines to the end of /etc/httpd/conf.d/ssl.conf file and restart httpd service
