I have some new information. Maybe these info can help. Thank you very much.
When I type ifconfig, then I got a message like this :
ppp0 : Link encap point-to-point protocol
inet addr : 203.130.227.76 P-t-P : 192.168.0.254 Mask :
255.255.255.255
UP POINTTOPOINT RUNNING NOARP MULTICAST MTU : 1500 Metric :1
RX Packets : 31 errors : 0 dropped :0 overruns : 0 frame : 0
TX packets : 16 erros :0 dropped :0 overruns :0 carrier :0
collisions : 0 txqueuelen : 0
Is this message want to tell me that ppp0 has up ?. But, at the startup,
there is a message :
Bringing interface eth0 [OK]
modprobe : modprobe : can't locate module ippp0.
modprobe : modprobe : can't locate module isdn0.
I was removed ISDN support on my kernel. (2.2.16)
And then, if I change my Gateway from 192.168.0.254 to 192.168.0.255,
then I ping 202.134.0.155 (my ISP) I get message :
ping : sendto : Network is unreachable.
ping: wrote : 202.134.0.155 64 chars ret -1
So, I change again into 192.168.0.254. And then on Linuxconf, (Networking ->
Routing -> Gateways -> Set -> Default) I enable option 'Enable routing'.
Then I try to ping 192.168.0.254. The result is like this :
64 bytes from 192.168.0.254: icmp_seq=0 ttl=235 time=178 ms.
But if I try again to ping my ISP, I get 100 % package lost. Also if I ping
using my ISP hostname (telkom.net.id). And then, because I'm using kppp
which it based on X, if I exit from X, I get a message like this :
Couldn't find interface ppp0 : No such device.
Couldn't find interface ppp0 : No such device.
Any help would be greatly appreciated.
