molto semplicemente: connessione adsl pppoe (user mode) tutto okei, però
linux 2.4 si connette in 1 secondo, linux 2.6 attende 20 secondi
(precisi) prima di connettersi. problema che c'è da sempre ma non sono
ancora riuscito a trovare nulla di utile...
quindi 2.4:
Dec 1 12:55:18 Axis pppd[2995]: pppd 2.4.2 started by root, uid 0
Dec 1 12:55:18 Axis pppd[2995]: Using interface ppp0
Dec 1 12:55:18 Axis pppd[2995]: Connect: ppp0 <--> /dev/pts/0
Dec 1 12:55:18 Axis pppoe[2996]: PADS: Service-Name: ''
Dec 1 12:55:18 Axis pppoe[2996]: PPP session is 41955
Dec 1 12:55:19 Axis pppd[2995]: PAP authentication succeeded
2.6:
Dec 1 12:56:47 Axis pppd[6249]: pppd 2.4.2 started by root, uid 0
Dec 1 12:56:47 Axis pppd[6249]: Using interface ppp0
Dec 1 12:56:47 Axis pppd[6249]: Connect: ppp0 <--> /dev/pts/0
Dec 1 12:56:47 Axis pppoe[6309]: PADS: Service-Name: ''
Dec 1 12:56:47 Axis pppoe[6309]: PPP session is 42019
Dec 1 12:57:07 Axis pppd[6249]: PAP authentication succeeded
look at timestamp
ovviamente stesso hardware/stessa configurazione.
ho sniffato il tutto con ethereal, se qualcuno gli può dare un'occhiata
(sono poche righe) e mi può dire a grandi linee dove sembra stare il
problema potrebbe essere utile per chiedere + info..
allego i files (minuscoli)
a me sembra che col 2.6 "unextech" (che sarei io, di preciso cosa?) non
da subito il "configuration ACK" ma continua a richiedere request per 20
secondi ogni 3 secondi, e poi da l'ACK.
