hello all experts. few days ago i do install "ufw" iptable rules app in my vps. but after done all settings and try to enable the ufw i got these errors and the application is not running..




This is my machine




Kindly help me to resolve this issue. due to this issue many of my server ports are misbehave or blocked

i read a news on the reliable tomshardware site that says some x570 boards may have features that reports reduced measures of some motherboard parameters (power consumption )to the processor and as a result, the processor gets boosted thorough automatic performance scaling algorithms causing even higher performance and resultant power consumption even in stock processor settings.
but the downside is more power to the cpu results in more heat that is gonna kill it faster. So be careful. here is the link..

https://www.tomshardware.com/amp/news/ry...u-lifespan

apparently, Intel had always endorsed motherboard manufacturers setting their own customised power consumption parameters to differentiate their motherboards / products. but this is not something AMD permits. it is the motherboard manufacturers.

result being, you get both the performance and penalty of overclocking even in stock settings and without knowing about it.

What is Jitter and what are its uses? What is the difference between Jitter and Ping?
In this article, all these questions will be answered.
Note: that this article was written by me and one of my friends helped me to write this article and translate it, so if there is a problem in translating the article, please help me by sending a private message or sending a topic.
Today I want to explain the concept of jitter to post4vps members .
And before I start, I would like to ask those any want to use this article for their website please put this website address of the post4vps forum as  source on their website to get a useful backlink for this forum. Otherwise, your work is a theft, and I, as the author of this article, am not satisfied with your work.(copy without perm...).

In very, very simple language, Jitter is the difference between the time our data packet passes from the moment it is sent to the network until it reaches its destination. To give a simpler example, look at two computers, either on an internal network or on a network with very large global dimensions, when they want to communicate with any communication device, whether a Telephone Tablet or even a website their communication is done through the transfer of information packets, these information packets remain on the network for a while to reach the destination, each information packet contains a header and footer and a number that is connected to the previous and next packet. The time it takes for this information packet to stay on the network to reach its destination is called latency.However, our information packages are not always received in a row and in order at the destination, but the information packages may be back and forth, and on the other hand, some information packages may be delayed by 20 milliseconds and others may be delayed. They reach their destination in 60 milliseconds, so there is a delay in normal networks and it doesn't cause any problems...This means that if you are watching an online news story or reading it, 20 milliseconds and 60 milliseconds is not much different for you and you can easily read it..The TCP // IP protocol itself is responsible for counteracting the impact of Jitter on networks. In networks used for VoIP communications, Jitter is very important, and if you send and receive data packets within 10 milliseconds. This delay should not be increased because the sound quality will be very low.
The shorter the delay, the better the quality of your service. In fact, when you want to send information from point A to point B, this information is sent in the form of information packets from point A to B at regular intervals.An information packet may reach in 20 milliseconds and an information packet in 10 milliseconds, and the next one in 60 milliseconds and this delay time is Jitter.
My purpose in posting this article was to help you understand the concept of Jitter in the shortest possible time.
Do not doubt that this article will be useful for you in the future and I hope this article has been useful for you.
If I haven't explained something and you know it, please teach us by sending a post in this thread. You can discuss in this thread.
Thank you for reading my article. I'm a writer, but I publish all my articles on my website, and this is the first article I've published on post4vps forum. Please give me reputation if this article is helpful.
good luck my friend's.

Hi folks,
Post4VPS will going to have a new theme in few months and probably all other themes get inaccessible( will try our best to keep them but no promises ).

The theme gonna be responsive.

We want to take User's opinions about which theme type they usually use.
Since now a days there is Dark mode available nearly everywhere ( like discord,whatsapp,android,windows, twitter,facebook,etc ).

Please use the poll to convey your interest and if you want them you can also explain below about how frequently you use dark mode in day to day life.

Regards,

Prologue:
This is a topic that was first published on the now defunct FreeFTPSpace Forums around 2014. I'm reposting it here, following the promise made in this post, in the hope to still be useful to others.

It should be noted that even though the topic focus was on Win7, the technique is also valid to any Windows 6.x, including Win10.

With windows 6.1 (Win7/Windows Server 2008 R2) [1], there is a new question that faces any sysAdmin when considering their deployment: "Do we want to install to a physical volume or a VHD?"

The routine, when you install an OS, is to select a volume/partition on a hard-disk drive and let the installation process dump it there. Your system's files and folders will then be visible/accessible when you explore that volume with any NTFS-aware file manager out there. The brand new stuff that shipped with Win 6.1 is that it gives you the option of performing that installation to a VHD file instead of a physical HDD's volume and boot natively from it.

1- What Are VHDs?
The virtual hard disk (VHD) format enables a single file to simulate a physical HDD, with its own volumes, file systems, and content. It was originally part of MS Virtual PC virtualization solution, which has been enhanced for use by Hyper-V, the new MS server virtualization platform.

Thus, to the computer, an "online"(/mounted) VHD file appears as a separate volume that can be treated exactly as any other volume on your hard disk. And, because you can store as many VHD files as you want on a disk, you can configure any Win 6.1 system to boot into different systems that you have installed in them without any repartitioning of your HDD.

Before showing how to mount and boot those VHD files, I must quickly say that for Windows 7, only the Enterprise and Ultimate editions can be configured to boot from them.

2- Mounting a VHD
The easiest way to attach/detach VHDs is through the Disk Management console:

1. open the Disk Management tool by typing diskmgmt.msc at a command prompt to access it.
   
2. in the Action option of the menu, you'll have the possibility of creating a new VHD or attaching an already existing one.
   

VHDs can be mounted with full read/write access or read-only. When attached, the VHD is assigned a drive letter like any other volume and can then be accessed through Windows Explorer.

3- Booting from VHD
This is really the feature that I was so delighted to find out in Windows 6.1 systems. It's very useful for multi-boot scenarios and provides an incredible ease in the portability of the operating system! As because the VHD image is a single file, you can easily back up the entire operating system environment by copying that single (+/- huge) file OR use it in a virtual environment (via HyperV, VirtualBox etc..)

The booting aspect of it boils down to the possibility of configuring the "new" Windows 6.1 systems' bootloader to start Windows from a VHD file exactly as if the VHD file were a standard partition.

Following are the 2 common scenarios that one might face:
> Installing Windows directly into a VHD (see 3.1) and
> Adding an existing VHD file (coming from another system or a virtual machine) to the boot menu so that we can boot from it (see 3.2.)
3.1- Creating a Bootable VHD Image from scratch
For the step-by-step that follows, we'll suppose that we start with an unformatted disk and we wish to install Win7 directly on a VHD file.
[ol]
[*]Boot from the Windows 7/2008 R2 media.
[*]Select the language option then click Next.
[*]At the Install Now screen, press Shift + F10 to open a command prompt window. This is done to partition our disk and create the VHD file that the operating system will be installed to.
[*]To select the targeted disk (in case we have many) and wipe its content do the following:
[*]Create a 100MB system partition, which the Windows 7/2008 R2 installation procedure normally creates automatically:
[*]We'll use all the remaining space to create a partition that will hold the VHD file. We'll call it "vFiles" and we'll assign the letter "D" to it.
[*]Now we'll create a VHD file on this newly created volume. In this example, the file will be an expanding disk with 20GB in size. Note that it's possible to use type=fixed instead of type=expandable to create a fixed-size VHD. Then, we'll attach it and partition and label it as "Win7-VHD"
[*]If you list the volumes on your selected disk now, you'll see your VHD partition online and waiting for you to install your OS in it:
[*]It's all done right now, so we'll exit Diskpart and then we'll close the command prompt window that we opened previousely:
[*]From here, you continue your OS installation as usual, but don't forget to select the "Win7-VHD" partition when asked for the installation target. Note however that a warning will appear stating that you cannot install it on the "Win7-VHD" partition when you select it, don't worry about that just ignore it and proceed as usual.
[/ol]

3.2- Creating a Bootable VHD Image from an existing file
Now suppose you have an existing VHD file that you wish to add to the boot menu and that you want to be able to boot from. This VHD could have come from any another system or even a virtual machine. The command sequence is as follows:

4- Things to keep in mind while working with VHDs

1. You should know that when you boot from a VHD, the pagefile is never created within the VHD file itself but outside within the first partition with enough spare space, starting from the hosting partition. Thus it is imperative to have extra empty space somewhere within the drive, or the VHD's system will boot and run without a pagefile!
   
2. Converting a regular Installation to a VHD File:
   It is possible to convert a physical installation of Windows to a VHD using the Disk2vhd tool from the excellent Sysinternals suite. The VHDs created by Disk2vhd are fully bootable.
   Thus you can use Disk2vhd to capture the system disk from an OS installation and then copy that VHD to a virtual server like M$$ Hyper-V and use it as the boot volume for a virtual machine or use it to Boot a physical machine from the created VHD....
   
3. VHD Limitations
   Bootable VHDs have a lot of benefits, but also some limitations. First and foremost, you can only create a bootable VHD with Windows 7 Enterprise and Ultimate editions. Other Windows 7 editions don’t support it. In addition, Bootable VHD images don't support hibernation and BitLocker, they can't be compressed and must be located on an NTFS drive.
   

That's it and Good Luck!

Authors Note for Win10:
If you want to use bootable VHD for Win10, please keep in mind that you won't be able to upgrade it when the next version is released.

I've already tried it, but each time Win10 refuses to do an in-place upgrade, which led me to end up with 3 consecutive Win10 versions on 3 separate VHDs. You've been warned!

Recently though, I migrated a Win10 VHD to QEMU/KVM but still didn't have time to test if I will be able to upgrade it in that environment.

Another possibility that I've recently tested (as of last week) is the brand new possibility to install Win10 inside an LXC/LXD VM (more on this in another topic.)

[1]- Vanilla Windows 7 and Server 2008 R2 have identical version and build numbers, i.e. 6.1 (Build 7600), because they were built from the same Windows code base.

Following our previous announcement about Hostlease's appointment of a new CEO, Dynamo and I are happy to announce that Jordy is back as owner and CEO of Hostlease. To avoid any confusion, there will only be one Hostlease Forum Account @Pacific Spirit.  The account of Monolithic Studios has been merged into the account of Pacific Spirit.

We still don't have an exact date when VPS 16, 17 and 18 will be reinstated again, however we will let you know as soon as Jordy has advised us.  We're hoping for it to be from mid-June onwards.

So far @Honey (VPS 16), @Decent12 (VPS 17), and @Rehan (VPS 18-1) have indicated they wish to continue as VPS Holders when the VPSs have been reinstated.  We're still waiting to hear from @youssefbasha for VPS 18-2, otherwise VPS 18-2 will be released for the July Giveaway.

• 4x VPS 1 [Games Servers not advised]
  
• 1x VPS 2
  
• 1x VPS 3
  
• 1x VPS 6
  
• 5x VPS 7  [Games Servers not allowed]
  
• 1x VPS 10 [Games Servers not advised]
  
• 1x VPS 11 [Games Servers not allowed]
  
• 1x VPS 12 [Games Servers not allowed]
  

We're aiming at a date of around 5th of June for announcing the winners.  VPSs will be allocated soon after.

Hi everyone, We have point credit system which we just use to decide winner of VPS plan. If 2 people requested for same VPS then giveaway manager see their usage of purpose and who have the most credits, There could be more factors obviously i don't know i'm not giveaway manager here, @deanhills is.

So how can we make point credits useful for more than just a showpiece.

Well here is some ideas, You guys are welcome to add more.

- First change symbol, It should be any currency symbol. Make something with "P"

- Ability to purchase small add not in header/Footer obviously sponsors are really important. Banner OR text format add smaller than "728x90" holding place could be between posts.

- Ability stick your thread for week or longer Advertising & offers board (Expect Free VPS Providers & Other Free Service Providers )


Point also have Statistics (fun fact: Been inactive for almost year and i'm still on top 10 with $1,970) Make a week OR monthly whoever earn the most points/credits in week/month will be the winner and prize could be ad placement or winner can have 2 VPSes. OR you guys suggest.

Please be advised that Hostlease will be resuming its sponsorship of VPS 16, 17 and 18 with effect of middle to end of June 2020. As previously reported, Hostlease was experiencing some serious KVM Networking issues that resulted in its cancellation of its sponsorship on 20 May.  After numerous discussions Post4VPS was asked whether Hostlease could resume its sponsorship after the KVM Networking issues have been resolved.  We were also advised that @"Monolithic Studios", the new CEO of Hostlease will act as new sponsor representative of Hostlease.  He will be replacing @Pacific Spirit who is no longer the CEO of Hostlease.  "Monolithic Studios" hopes to have VPS 16, 17 and 18 ready for redeployment from mid of June, but we obviously need to be patient as there isn't a definite date available yet.

Regarding the current VPS Holders of VPS 16, 17 and 18.  Initially we thought we still had access to VPS 16, however without being previously advised, all four of the VPSs have been powered down by @"Monolithic Studios" and Post4VPS no longer has access to the Hostlease VPS Control Panel.  With regard to VPS 16 the status is still the same in that the sponsorship of VPS 16 will come to an end in October.  Sponsorship of VPS 17 and 18 will resume unaltered after they have been fixed until further notice from @"Monolithic Studios".

VPS Holders of VPS 16, 17 and 18 have a choice.  If you cannot wait for that long, you may apply for a new VPS during our 1 June Giveaway and of course surrender your Hostlease VPS for inclusion in the 1 July Giveaway.  For Hostlease VPS Holders, if you wish to keep your current VPS, can you please re-confirm your original VPS Request as soon as the VPS Request Forum has opened again on 1 June and I have unlocked your original request.  I.e. for VPS 16, @Honey, if you want to keep VPS 16, can you please go to your original VPS 16 Request, as soon as the VPS Request Forum opens, then reply to the Request confirming that you want to continue using VPS 16 when it is has been reinstated by Hostlease.  The same with the VPS Holders of 17 and 18.  For Hostlease VPS Holders who wish to keep their VPS there obviously won't be a posting requirement for June as long as the VPSs are powered down.  We will advise you of the status of posts as soon as the VPSs are ready for use again.
