cell phone modem - more info

[zaurusbs]

okay, so i managed to connect and dial at least, but i can\'t seem to keep the connection or actually get net access. here are the contents of qpe-pppd-log - any and all help is most appreciated.

thanks!

Have you put the correct username/password combo in /etc/chap-secrets ?

[zaurusbs]

i checked the chap-secrets file, and it does have the username and password for this connection and the others that i tried. it\'s in /etc/ppp/
i\'m trying to get in using roadrunner dialup, which uses a login script. this is what it is on windows:
http://www.brettsinger.net/temp/login.scp.txt
i guess i need to invoke the script somehow. this is my first time doing this in \'nix, so any advice on it would be great.

[lardman]

I\'d have thought you could stick this in your chat script pretty easily. Which one of the myriad methods do you use?    ANSNet, UQKT1, Sprint-IP, etc....

Take a look at the ppp howto from www.tldp.org.

Can you also post your peers file which is in /etc/ppp/peers and has the same name as your connection (DialupModem1074271674 I assume)

where would the chat script be? usr/sbin/chat? also, can i use it verbatim or does it need to be \"reinterpreted\"? i\'m not sure which one of the methods are actually used, since i\'ve only ever tried to connect to this ISP on windows.

Take a look at the ppp howto from www.tldp.org.

is this what i need?

thanks so much.  here are the contents of DialupModem1074271674

115200
connect \'/usr/sbin/chat -s -v -t 60 ABORT \"NO CARRIER\" ABORT \"NO DIALTONE\" ABORT
\"BUSY\" \"\" \"ATZ\" OK \"ATDT12123810006\" CONNECT\'

[lardman]

ABORT \"NO CARRIER\" ABORT \"NO DIALTONE\" ABORT \"BUSY\" \"\" \"ATZ\" OK \"ATDT12123810006\" CONNECT  

That\'s the chat script.

It would probably be possible to put in the stuff which you had in your login.scp.txt file, try each method one at a time.

In any case you know that the password must be prefixed with \"aolnet/ent.\"? So I\'d try doing this for the password in your chap-secrets file before trying anything else.

is this what i need?  

http://www.tldp.org./HOWTO/ISP-Connectivity-2.html  

That looks like it might be useful, a few more are:

http://tldp.org/HOWTO/BTI-PPP/index.html (not strictly related, but you need to understand ppp and chat scripts)
http://tldp.org/HOWTO/PPP-HOWTO/index.html

If altering your username doesn\'t work, I\'ll see what I can do with the chatscript.


Si

[zaurusbs]

okay, i edited chap-secrets and added \"aolnet/ent.\" as a prefix to the password, but no dice.
where would i put the info in login.scp as a script?

[lardman]

Oops, it\'s supposed to prefix the username, my mistake (it\'s in the txt file you linked).

I\'d put the info in line in place of the bit I quoted above (in fact it would need to be tacked on the end). I don\'t know whether this will work, but it\'s something to start with:

115200
connect \'/usr/sbin/chat -s -v -t 60 ABORT \"NO CARRIER\" ABORT \"NO DIALTONE\" ABORT
\"BUSY\" \"\" \"ATZ\" OK \"ATDT12123810006\" \"ANSNet\" \"\" \"login\" \"aolnet/ent.\"+$USERID  CONNECT\'
crtscts
noipdefault
modem
user \"rsinger1\"
usepeerdns
defaultroute
connect-delay 1000
remotename DialupModem1074271674

[zaurusbs]

okay, sorry to be dense - but where do i put this script? in DialupModem1074271674? somewhere else?

[lardman]

Yes, backup your old one and then paste the above in on top of what was there.

If you leave the aolnet/ent. prepended to your username in chap-secrets then you can change part of the above from:

connect \'/usr/sbin/chat -s -v -t 60 ABORT \"NO CARRIER\" ABORT \"NO DIALTONE\" ABORT
\"BUSY\" \"\" \"ATZ\" OK \"ATDT12123810006\" \"ANSNet\" \"\" \"login\" \"aolnet/ent.\"+$USERID CONNECT\'

to

connect \'/usr/sbin/chat -s -v -t 60 ABORT \"NO CARRIER\" ABORT \"NO DIALTONE\" ABORT
\"BUSY\" \"\" \"ATZ\" OK \"ATDT12123810006\" \"ANSNet\" \"\" \"login\" $USERID CONNECT\'

this is a huge help, thank you.
a question: i think i may have screwed up chap-secrets or another config file (since i was at one point able to at least connect to the phone and dial but now i can\'t). is there any way to get back to the default version of the various configuration files?

[lardman]

chap-secrets is fairly simple (http://www.netsoc.ucd.ie/LDP/HOWTO/PPP-HOWTO/x1053.html), and isn\'t needed to dial the phone, so I guess that messing with the peers file may have done it.

One thing to check is that you don\'t edit this file using either a Windows program or the standard Sharp ROM text editor as both add line feeds which Linux doesn\'t like. If this is what you\'ve done then try this program to get rid of them: http://www.killefiz.de/zaurus/showdetail.php?app=157

Otherwise you could always paste in what you gave us above.

The only other things are the various default settings in /etc/ppp, did you do anything with these?

Si

P.S. I guess that the default files are stored in the hidden tar file which contains the /home directory. I don\'t remember where it is though, but there are doubtless some posts which will tell you.

i now have multiple DialupModemXXXXX files. now there are two, and both have different numbers than before. what\'s that about? could that be what\'s causing this problem?

nope, just vi to edit all of these.

you know, i don\'t think so, but i just did an ls -l and found that options.ttyS3 is listed as modified today.

at this point i just hope all of the taking the cable in and out of the phone didn\'t break the connector :-(

[lardman]

You could always try to create a new connection in the same way as you did before.

Otherwise I\'d put the name of the file in /etc/ppp/peers/ back to DialupModem1074271674 and see whether that works. I\'m afraid I\'ve not used the dialup capabilities for a long while and am having difficulties trying to remember how the peers file is associated with an individual dialup.

You may find that the other files which may have been modified are located in a hidden tar file /root/.home_default.tar (try \'ls -a /root\') as they are on the 5500, I\'m not sure for your machine though.
