Öntanımlı dhcpcd timeout süremiz 20 saniye. Bazı kartlarda bu süre yeterli
olmuyor. e1000 ve skge sürücüleri kullanan kartlar bir örnek.
dhcpcd 3.x serisinde dhcp'den ip alamıyor diyerek 2.x serisine geri döndük ama
burada sorun bir olasılık timeout süresi idi. Bir de daha önceden bir yama
linki vermiştim. Bu yama zaten kullandığımız 3.x serisi içerisindeymiş. Yani
3.x serisi 2.x serisine göre daha bir sorunsuz aslında. dhcpcd 2.x'in ip
alamadığı çok oluyor.
20 saniye'nin yetmediğini ekteki dosya'dan çıktıları takip ederek
görebilirsiniz. Kart e1000. İlk testlerde dhcpcd 2.x serisi kurulu. Ip alma
timeout'unu 60 saniye veriyorum, bir sefer almayı beceriyor ardından 60
saniye dolmasına rağmen alamıyor arka arkaya.
Arada 3.x e upgrade edip deniyorum ve yaklaşık 30-35 saniye sürmesine rağmen
alıyor.
Önerim dhcpcd 3.x serisine geri dönelim ve timeout'u 60 saniye yapalım. Alan
zaten alabiliyor kısa sürede. e100 kartlı makinemde 5-10 saniye arası
sürüyor. Geç alana da 20 saniye timeout yetersiz geliyor.
Aslında daha da güzeli dh-client'a geçmek. Dağıtımların çoğu buna geçmiş
durumda. Baktığımda ip alma süresi aslında yine uzun sürüyor fakat geçte olsa
alıyor. Kodlarını da inceledim biraz ve dh-client çok daha temiz görünüyor.
2008 için dh-client'ı düşünelim; 2007 serisinde 3.x'e yeniden geçelim ve
timeout'u 60 saniye yapalım derim.
