Birkaç alt ağ için DHCP çalıştıran bir CentOS 5 sistemim var. / Var / log / messages dizininde, sabit DHCPINFORM, DHCPACK ve DHCPREQUEST iletileri görüyorum. Bu isteklerin neden diğer kurulumlardan daha sık olduğunu anlamıyorum. Mesajlar birkaç saniyede bir patlar ve son derece büyük günlük dosyaları ile sonuçlanır.
Buradaki cihazların çoğu kablosuz el cihazlarıdır (Windows CE TCP yığını kullanarak). Sürekli mesajları sorgulamaya ilişkin her türlü anlayışı takdir ediyorum.
