What ever shall I do? (netwk/hardware Q)

[A. Buza]

For the past month or so, I've been trying to get my linux box(which is on a spiffy LAN) set up as a dial-up PPP server for my dreamcast to connect to. It hasn't worked yet.

I've read everything I could on the specific subject, and on the more general subjects of modems, serial ports, IP forwarding, PPPD, mgetty, etc. I've posted my problems on usenet forums, and have tried to find others with the same problem as me. However, I've still had no luck getting it to work.

It looks like you guys are my only remaining hope. Anyway, here's the deal, hopefully someone can help,since I feel as though I'm so close to getting this to work:

I have a linux (RH 6.1) pc connected to a lan using standard ethernet stuff. I also have a modem (external, hayes 56k). I am attempting to set up a dial-in server which my dreamcast can use for internet access. The PC and DC are connected directly (i.e., no going through the standard phone lines/phone co. i.e., no dial tone).So far, I've gotten the linux modem to make noise (although it isn't like any dialing noise I've heard), but then the DC disconnects with the message 'no carrier'.

Here are the relevant config files:
DC IP = 192.168.0.1

/etc/inittab/
#blahblah
S1:2345:respawn:/usr/bin/mgetty ttyS1 -x9
/etc/inetd.conf/
#udpred stuff
21050 dgram udp wait root /usr/sbin/tcpd /usr/bin/udpred 192.168.0.1 21050


/etc/ppp/options.server
debug
require-pap
default-asyncmap

I think everything else is set up correctly but I could be wrong so please tell me if anything else would help others resolve my problem.


Thanks for your time... I hope I can get this working eventually.

I can't help but I might be able to point you in the right direction. Slashdot had a story about doing this, I don't if this is where you got the idea or not but you'll find links there. Also, www.linuxdoc.org (http://www.linuxdoc.org) has howto's on using RedHat as an ISP. You might also want to skim slip/plip stuff for hints.

Yeah.. I already saw the article, and have read the HOWTOs on PPP, mgetty, etc.

Thanks for trying, though :) I appreciate it.

I Just checked the logs... hmm.. signal 15, does this mean anything to anyone? I looked around and couldn't find much info..

/thelog/
03/11 04:03:03 ##### failed dev=ttyS1, pid=524, got signal 15, exiting


Theres a whole bunch of other debugging info (modem init/setup stuff I assume). If this would help anyone to help me solve my problem, I could post it.

*peers and notes a challenge*

You have the dreamcast box calling the linux box to connect to the internet?
--The linux box has an established connection to the internet?

*shakes head* ...Dreamcast is a sega game machine isn't it?

what they're doing with plastics nowadays.. *grin*

The dreamcast presumably has a builtin modem that is picking up and connecting to the external modem on the linux box.
The dreamcast is calling the connection a no carrier fail. You appear to have debugging on in your ppp-options-server file.. what are the ppp logs saying about the connection? (These should be in /var/log/pppd ... *if* my memory serves...)

It is entirely possible that the modem settings on the dreamcast are something that does not agree with the encoding on the linux box. (unix standard is actually 7-none-1 not 8-none-1) ... as to setting them to agree I'm not sure and would depend also on the modem.

I'll at this in a little more depth later today.
