I may have a suggestion for those running the CWP on a linux distribution.
To improve the  upload to your webclients you can implement a different way how the TCP stack is handeling the requests.

Enable TCP BBR and other network stack optimizations
BBR is a new congestion control agorithm which dramatically decreases the time needed for a TCP connection to ramp up to maximum speed. It also contains improvements to counter other problems like router buffer bloat which causes network latency spikes.

To enable BBR you need you have kernel version 4.9 or higher. See your kernel version with uname -a. On Ubuntu you can upgrade to a newer kernel by enabling HWE.

Create a file called /etc/sysctl.d/60-bbr.conf with the following contents:

Code: [Select]
net.core.default_qdisc = fq_codel
net.ipv4.tcp_congestion_control = bbr
net.ipv4.tcp_notsent_lowat = 16384
net.ipv4.tcp_slow_start_after_idle = 0

After doing that you can run sysctl -p or reboot to apply the changes.
Verify that itís working with this command: sysctl net.ipv4.tcp_congestion_control. It should return bbr.

Here a link to get more information on how to test it before and after implementation.

PHP / Failed to Download PHP version 8.1.2!
« on: January 31, 2022, 01:17:07 PM »
After going to the PHPO switcher and telling i want to upgrad from 8.1.1 to 8.1.2 the tail log gives me this  message after about 3 minutes

/usr/local/src/ line 78: [: -ge: unary operator expected
Failed to Download PHP version 8.1.2!

i tried this on 2 equal same machines and both have same error.

the machine doesnt finish anything and the version stays 8.1.1

Hi Sandeep,

Thanks or the reply.

Why is that done this way ? does it mean you cant use or are advised not to use redirection module when you run other then apache ?



I wanted to redirect a domain name i host on my server to another server that i dont own, so i was looking for the redirect option under domain options in the userpanel. It is not there to be found as you can see.

However, when for example i click one of the modules under the domain option and i click with my mouse on the address bar and change the clicked module name into "redirect" i do get the redirect page / module and i can do the things i wanted... and it is still functioning as you can see

So my request to the makers / programmers, is it possible you just put the redirect link in function back in the domain menu again ? That is more convenient to access and a less hassle

Thanks in advance

im running centos 8 stream updated to the last updates

CentOS-WebPanel GUI / Re: Copy files to another folder not working
« on: November 22, 2020, 11:48:48 PM »
I am running it on a sabrent rocket 2tb nvme pci 4.0 disk. so im pretty sure its not my disk is to slow.

its simple. i have a folder i upload all the zipped files in i need to update for example drupal. i use the extract command. works fine and a drupal file is about 30 mb.
then i go inside the drupal folder select all and use the command copy. i select the new folder and click copy. it almost immediatly gives the screen that its done.. but when i go to take a look in the destination folder.. nothing happened. no new files copied.

when i choose move instead.. it moved all the files in the root folder.. but all the sub folders are being left behind.

it all worked fine before, until the update came to the new file explorer. so you must have changed something.
where can i find the logs for the file manager to find out the issues it had during the copy or moving ?

I have exactly the same experience....
the graphical starts to spin and u can wait for hours... only 1 folder is being made but empty..

it doesnt work anymore since the update of the file manager.

I just found out... when i choose MOVE instead of COPY... it works half. the source folder is empty and the target folder looks like to be filled up... but isnt. folders are moved but the content inside the folders, half of is missing or miss placed in the wrong folders.

I installed as a vm a new centos 8 minimal and choose for cwp8 with the installation.
But after i logged in it still shows me cwp7 pro in the upper left corner.
Is that ok ? or did something went wrong ?
Does it has to show somewhere cwp8 pro ?


Hi Sandeep and Team.

Thanks for solving


Hi Sandeep,

i havbe been trying some more, the installation with the version switcher looks ok at first but it still not installs complete and ends hanging  in the log and my my panel still working in php 7.3.19

the selector issue is still the same. i upload some log files for you in the case you want to see where it goes wrong
hope u able to find it soon



i tried to install PHP-FPM 7.4 through the selector in the panel, but it doesn do anything.
When i look in the log file and in my console with the command tail -f /var/log/php-selector-rebuild.log i get this as output:

Backup / New Backup 2
« on: February 16, 2020, 10:12:26 PM »
Implementation of improvement requested.

So far im using the new back up  and its functioning well. I am just missing the option to name the file.
I would like the output file name to be able to manual configured, or that you guys put the date of creation in the file name.
Now the file name on the remote location is the same everytime.

I have no idea where the scripts are that i can do it myself, otherwise i would.

But just add / append the creation date and time to the file name so u can have multiple offsite file backups a day

CentOS-WebPanel Bugs / Missing start buttons in service status windows
« on: September 14, 2019, 09:42:19 PM »

I had a working installation before.. and after updates i noticed im missing the start buttons in the service status window.
I been checking and testing but could not find a solution. Since im still learning and playing around.. i decided to make a new installatation on a VM and work from there.
I was even more surprised that after a fresh installation the buttons still missing.

Ido run cwp pro

See attachment

so what to do ?
