Is the symbolic link from /dev/modem to /dev/ttyS* required to make PPP run?
The origin of this question is that I have been attempting to setup PPP on
my RedHat Linix 5.1 box to an external Hayes Accura 288 modem with an ancient
secial card that uses a 450 chipset. I am using chat and have the interface
ahd the modem set up to use rts/cts hand shaking at 38.4Kbps. When I fire
up the script it successfully picks up the modem, dials the ISP and chats
its way through a successful login and using 4 LCP packets and 6 IPCP packets
it seems to setup a proper ppp connection and then nothing. I can send an
infinite supply of packets to the ISP but not one packet comes back, ever.
I wrote my scripts to refer to /dev/ttyS1 and I can successfully connect to my
ISP (which I also administer) but then nothing happens. The ppp connection
sequence is logged something like this:
Mar 21 08:06:26 (none) pppd[337]: pppd 2.3.3 started by root, uid 0
Mar 21 08:06:51 (none) pppd[337]: Serial connection established.
Mar 21 08:06:52 (none) pppd[337]: Using interface ppp0
Mar 21 08:06:52 (none) pppd[337]: Connect: ppp0 <--> /dev/ttyS1
Mar 21 08:06:26 (none) pppd[337]: local IP address 111.222.333.121
Mar 21 08:06:26 (none) pppd[337]: remote IP address 111.222.333.2
An ifconfig at this point shows that each host has sent 5 packets down the
wire but after that if I ping the remote host or the dns or whoever I get
only outgoing packets and no incoming packets.
The other thing that interests me here is that my local hostname is (none).
This is setup using DHCP so I didn't think about that but I was comparing notes
with a working Linux PPP client and found that it calls itself localhost.
Where have I gone wrong?
