It looks like ppp is doing a lot of read and write operations, which keeps
the disk spinning. How do I set this right ? Is there something wrong with
my ppp.conf (see below) ?
set log Phase Chat LCP IPCP CCP tun command
allow users bourne
# ident user-ppp VERSION (built COMPILATIONDATE)
set device /dev/cuaU0.0
set speed 115200
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
\"\" AT OK-AT-OK AT&FE0V1X1&D2&C1S0=0 OK \\dATDT\\T TIMEOUT 40 CONNECT"
set timeout 180 # 3 minute idle timer (the default)
enable dns # request DNS info (for resolv.conf)
set phone "#777"
set authname "internet"
set authkey ""
set timeout 180
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
add default HISADDR
