Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

i have windows 2016 server
I have data coming in on port 3299
When i hits the server i need to remap it to port 9013 as there is an app on this server which is listening on this port

is this possible/
There is not router, the server sits directly on the internet so it needs to be done it windows

Hello,

If I am running a tcp ping tool on a virtual windows server that is hosting my website also, would it be possible to use the tcp ping tool to ping the visitor of my website to record the latency/round trip time without the stateful firewall blocking it?

The issues I came up with would be that all/most home-based firewalls are stateful firewalls, tcp communication can use only one IP and one port(if I am correct?) per application (website in this scenario). So I would have to have the tcp ping application listen in on the port using another IP, or open a new port (and IP) to communicate with the same website user. So my second question would be: would the stateful firewall block this communication since it is from a different port and/or IP even though it's on the same web server?

Regedit \ RouterManager can be configured ?

Regedit \ TCPip6 every modified would be return to previous state, as motherboard changed, DUID mac info inside needed to , RFC3315 required .

When the OEM vga driver latest supported driver updated to Nov. 2018, whatever way tried, the computer Driver Manager can not see the latest date of the offering ?

Hi, i have problem whith download Decrypting Cryakl from https://www.experts-exchange.com/articles/31579/Decrypting-Cryakl-1-4-0-0-1-4-1-0-FAIRYTAIL-Ransomware.html  (and decryptors.blogspot.com). Can help me whith download application?
I want test on CL 1.5.1.0. I have one pc whith this encryptor. I know that he was installed through the RDP, and have some files and log's. Maybe you decryptor can help.

Can someone explain to me where consensus algorithms fit within the TCP/IP model?  Let use Raft as an example.  Does it use multicast?  Does it use it's own transport number or TCP/UDP?  Does it live on the application layer?

I am trying to run an inventory on our servers. All I get in return are DCOM errors in event logs. I speculate the firewalls are blocking traffic but I cannot see anything helpful in Wireshark. I thought that telnet over 135 would fail but does not. Also ICMP is not blocked or I would not be able to ping the servers

Event Viewer
DCOM was unable to communicate with the computer XXXXXX using any of the configured protocols; requested by PID     2780 (C:\Windows\SysWOW64\cscript.EXE), while activating CLSID {8BC3F05E-D86B-11D0-A075-00C04FB68820}.


I have attached the Wireshark capture

I'd like to redistribute eigrp into bgp on the Nexus 7009. I'd also like to set the correct metric. From my understanding, I have to use route map. I did some research and could not find any good info. Any helps will be greatly appreciated.

Hi... Can anyone tell me what is this Simple Network Audio Protocol running on port 4752 ? Thanks

We have a client who has just had installed a BTNet Leased line installed.
They have 8 static (5 usable) IP address on the line (/29 subnet) assigned. Lets say this is 122.122.122.0/29
We have configured the WAN1 of the Draytek with this range and configured the WAN IP address as 122.122.122.2, subnet 255.255.255.248 and its Gateway to point to 122.122.122.1

Connected a PC to the LAN1 and LAN2 Ports on the Draytek which allows us to access the Internet OK - All Works OK from LAN to WAN.

We are now trying to Port Forward specific ports (lets say 22 and 23 - SSH and Telnet) on the next useable IP address (122.122.122.3) through to a device on LAN2 which has been configured on a different LAN/Local Subnet (192.168.2.0/24). The device is on an IP address of 192.168.2.2, LAN2 IP on Draytek is 192.168.2.1

The Draytek can ping to the device with an IP of 192.168.2.2 but we cannot seem to get the NAT/Port forwarding to work correctly.

We have tried using One to One NAT for this solution along with a Firewall rule to allow WAN to LAN2 traffic for these ports. Logging (SYSLOG) is turned on for this rule but no traffic is ever reaching the firewall rule as no logs are produced.

To see if we had set something up wrong we have also tried port forwarding these ports on the first WAN1 IP address of say 122.122.122.2 but again nothing is logged with SYSLOGS

This is the first time we have tried configuring a Draytek, usually use Zyxel firewalls without any issues so I was …

Hi

i configured OSPF between cisco ASR and Juniper router (service Provider).

OSPF neighbour has formed and exchange routes.

but ASR is logging a message " Cannot see ourself in hello from <juniper router id>, state INIT"

This is not happening all the time. its happening randomly once or twic a week. Mostly happening duing the peak hours of the business (but traffic is not hitting the maxium BW).

Due to this i can see some of the remote sites having high latency connecting to the DC for 2 -3 min and then when OSPF is normal the high latency is goiing away.

Not sure why the OSPF is flapping. Any particular config i need to add between juniper and Cisco ASR to Work.

regards
Logesh

Dear sirs,
I am setting up a global exception handler in Spring. Once an exception is caught, a method in the @ControllerAdvice is called in, and returns a specific view with exception details. Among info returned with the view, I have the HttpStatus, that can get. Actually I keep getting 200, while the right HttpStatus should be 500, 404, etc.
Here is my code
@ControllerAdvice
@Slf4j
public class AppGlobalExceptionHandler {
      /*
       * Note: You can either point to Exception Types or Http ResponseStatus
       * @ExceptionHandler({MyException.class})
       * public String ...
       *
       * @ExceptionHandler
       * @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
       * public String
       * */
      
      @ExceptionHandler
      public String handleAnyException(Exception exception, Model model,
                  HttpServletRequest request, HttpServletResponse response) {
            
            log.error("Request raised " + exception.getClass().getSimpleName());
            
            String details = ExceptionUtils.getStackTrace(exception);
            
            AppError error = new AppError();
            error.setStatus(response.getStatus());
            error.setUrl(String.valueOf(request.getRequestURL()));
            error.setMessage(exception.getMessage());
            error.setDetails(details);
            
            model.addAttribute(AppStringHandler.VARIABLE_URL_SUBMIT, AppStringHandler.URL_TASKS_SEND_EMAIL_500);
            model.addAttribute(AppStringHandler.VARIABLE_URL_REDIRECT, AppStringHandler.URL_ADMIN_REDIRECT);
            model.addAttribute(AppStringHandler.VIEW_ERROR_MODEL_ATTRIBUTE, error);
