Holat (holat) Tinglash Shou passiv ochiq ulanishlar ("Eshitish" rozetkalari). Ular tarmoq xizmatlarini taqdim etishmoqda. O'rnatilgan - Bular o'rnatilgan ulanishlar, ya'ni ulardan foydalanish jarayonida tarmoq xizmatlari.
Tarmoq xizmatlarining mavjudligini tekshiring
Tarmoq xizmati bilan bog'liq muammolarni aniqlagan taqdirda, ushbu OSda ularning mavjudligini tekshirish uchun turli xil diagnostika vositalari qo'llaniladi.
Eng qulay vositalardan biri - TCPTraceroute buyrug'i (TCPTROUPEREE ACK), ko'rsatilgan xizmatni (Standartlar bilan) o'tkazadigan va xostning veb-serveri, 80-sonli) TCP-lar-ning ushbu turini yo'ldoshlar orqali o'tish vaqti, shuningdek, mezbonlarda xizmatni qiziqtirgan yoki paketlarni etkazib berish bilan bog'liq muammolar yuzaga kelganda, ular qaysi joyda paydo bo'lgan.
