मेरे पास कई सबनेट के लिए डीएचसीपी चलाने वाला सेंटोस 5 सिस्टम है। / Var / log / संदेश में, मुझे लगातार DHCPINFORM, DHCPACK और DHCPREQUEST संदेश दिखाई दे रहे हैं। मुझे समझ नहीं आ रहा है कि ये अनुरोध अन्य स्थापनाओं की तुलना में यहाँ अधिक क्यों हैं। संदेश हर कुछ सेकंड में फटते हैं, जिसके परिणामस्वरूप बहुत बड़ी लॉगफ़ाइल्स होती हैं।
यहां उपकरणों के थोक वायरलेस हैंडहेल्ड डिवाइस (विंडोज सीई टीसीपी स्टैक का उपयोग करके) हैं। मैं निरंतर संदेशों को समझने में किसी भी अंतर्दृष्टि की सराहना करता हूं।

कुछ डीएचसीपी सर्वर-साइड राउटर्स से कुछ एक्सट्रॉनिक एंट्रीज को हटा दिया है । बहुत से ट्रैफ़िक कम हो गए हैं, हालाँकि मुझे अभी भी बहुत से DHCPINFORM, DHCPACK मिल रहे हैं ...
