Трасіровка на конкретний порт

Щоб перевірити доступність певного TCP-порту на маршруті передачі даних, потрібно виконати наступні кроки:

Крок 1: Завантажити програму та встановити програму WinPcap

Крок 2: Завантажити утиліту tracetcp, розпакувати архів та скопіюйте файл tracetcp.exe у одну з наступних системних папок: C:\WINDOWS або C:\WINDOWS\system32

Крок 3: Відкрий CMD

Крок 4: Для запуску tracetcp, введи команду tracetcp у вікні командного рядку та натисни клавішу Enter.

Приклад використання:

tracetcp host [options]
    where host = hostName|ipAddress[:portNumber|serviceName]
    if portNumber or serviceName is not present then port 80 (http) 
    is assumed.

Options:
    -?            Displays help information.

    -c            Select condensed output mode

    -h start_hop  Starts trace at hop specified.

    -m max_hops   Maximum number of hops to reach target.

    -n            No reverse DNS lookups for each node.

    -p num_pings  # of pings per hop (default 3).

    -r p1 p2      Multiple traces from port p1 to p2.

    -t timeout    Wait timeout milliseconds for each reply.

    -v            Displays version information.

    -s p1 p2      Easy port scan mode. gives the same result as
                  setting the following options:
                  -cnr p1 p2 -h 128 -m 1 -p 1

    -F            Disables the Anti-flood timer. Normally tracetcp
                  waits *at least* 0.5 seconds between sending out 
                  each packet, because if the packets are sent too 
                  fast some host seem to detect this as some form of 
                  flood and stop responding for a time. This option 
                  disables the 0.5 second timer, so the traces occur
                  faster.

    -R            Use raw socket interface to send/receive packets
                  this will not work on XP sp2. 
                  (you still need winpcap installed)

    -g address    use the specified host as a a gateway to remote
                  systems rather than the default gateway.


Examples:
    tracetcp www.microsoft.com:80 -m 60
    tracetcp post.sponge.com:smtp
    tracetcp 192.168.0.1 -n -t 500
