How are local ports determined The port number is chosen by the TCP implementation software from a range of port numbers called Ephemeral Ports. The exact mechanism for choosing the port number and the range to be used is Operating System dependent. Is there a way of forcing it to be 63999. Not without reprogramming the TCP implementation software. The Ephemeral Port Range A TCP/IPv4 coection consists of two endpoints, and each endpoint consists of an IP address and a port number. Therefore, when a client user coects to a server computer, an established coection can be thought of as the 4-tuple of (server IP, server port, client IP, client port). Usually three of the four are readily known ...

I have an exteal hard disk, and for some reason, it is reporting wrong free space. In Windows Explorer, it is showing the used space is 378 GB. I tried ruing chkdsk H: /f /r, it seems to report the same usage as Windows Explorer, and it says that there is no problem. But when I tried selecting all the files inside this drive, it is showing much lesser usage. I've already set the setting to show all hidden files and folders, also show the protected OS files, but it still caot find about those missing files. And the difference is huge (282 GB). I've already cleaned the Recycle bin as well. What I am missing here and how do I identify those missing spaces? Let's block ads! بخوانید...

I've a question about SSH reverse tuel. I've an ubuntu server with sshd installed. I open ssh reverse tuel from a remote machines, on that machine the coection is restarted every time the tuel is interrupted. Whenever a tuel is opened, on the SSH server i can see two coection using netstat. One listening to the interal server port. Then other on an exteal port. The latter one is the SSH tuel. As example. given 138.10.20.10: my ssh server and 10.34.23.12 my remote pc, 5000 the port on my remote pc i would like to access to ssh -R 1122:localhost:5000 [email protected] Now server side i've two listening coections, which looks like this tcp6 0 :::1122 :::* ...

I have a Synology NAS (DSM 5.4) on which I run an OpenVPN server (on port tcp/1194, IP is 192.168.1.10). I have forwarded the port 64666 on my exteal IP to that address and port on my access router (a TP-Link AS1200). The problem: I caot coect with an OpenVPN client from an inteet host: Tue Aug 23 15:05:37 2016 Attempting to establish TCP coection with [AF_INET]myip:64666 [nonblock] Tue Aug 23 15:05:47 2016 TCP: coect to [AF_INET]myip:64666 failed, will try again in 5 seconds: Coection timed out (...)

I believe with Arris you would need to go to virtual server configuration. Then you would need to put an inbound port (whatever port your camera system listens on). Then the local port (same as camera system listens on) as well as an IP (inteal IP of camera system). Then browse to that IP (Exteal) and see if you can hit it. Once you can, there are plenty of port scaers online that will tell you if it's open and listening. I usually use MxToolbox Let's block ads! بخوانید...

Background: A few days back I wanted to play AOE2 over inteet. For that I used Voobly application for finding the users and launching the game. But problem was that since my local ISP had blocked port 16000, I was unable to play. I asked the local ISP to forward the port 16000 and they didn't know what did that mean. After that I installed Hideme VPN application and it somehow did the port forwarding and I was able to play. Question: How does the VPN overcome the port blocking restriction? Isn't all the traffic still go through my router, so then how did that happen? Note: I first asked this at Network Engineering , they told me to move it here. Let's block ads! بخوانید...

Hard Drive checking in Windows reports a lot of uecessary info, requiring that you read through it the chkdsk report, etc. Also chkdsk can't fix problems on an in-use files (like the Windows drive). It seems like a little thing, but a non-technical user can't understand ChkDsk results and it takes even a technical user a minute to read through the report for each hard drive. Is there a tool or built in service which will: Automatically check all drives for errors Report a simple "no problem" or "problem" Ideally, schedule a repair operation on the next restart. Bonus points: restart the computer to do the repair, and report all of that. Let's block ads! بخوانید...

I have two HP Z27s 4k monitors coected via DisplayPort to my hp PC ruing Windows 7. Due to issues related to font scaling, I've been ruing both for at least a month at 2560x1440 without significant problems. [I was getting some random banding that powering the monitor off and on fixed.] Today, one of the monitors started flickering ~2"-tall horizontal bands of noise at random places on the screen. In an effort to fix that, I set the Refresh rate to 30 Hz (it was 59 Hz on both monitors). When I did that, the display on that monitor shrunk down to not being scaled at all. That is, there appears to be a 2560x1440 display centered on a 3840x2160 monitor, with significant (4" R & L, 2" T &...
