I have spent 3 days now trying to get ppp to work and now ask in some
despair for help.
I have been through the redhat ppp set up, ppp how to and several hundred letters on
dejanews to no avail and in this time seem to have encountered every known error
(seial line looped, peer refused authentication, files required but not accessible,
LCP t
imeouts etc) and can only take my hat off to those who succeed first time.
I have tried to summarise below what I thing is relevant in the hope that someone may
have some ideas in how to progress.
It is difficult to progress as I work alone and therefore have no colleagues to help
me in pulling my hair out.
I am trying to connect to a dial in service (not on the web) which uses chap
authentication such that I can have a program on my web server call this as required
to ask some questions and then return the answers via a web page.
After failing I tried some more basic work by connecting to a local ISP where I
normally login via windows ok.
Both services connect fine through windows using modem and cable I am using. (If I
knew how to both write and ommunicate with a windows program then I would even do
this, but unfortuately(?fortunately) I don't.)
I have a web server with its own DNS connected to the web via direct link.
I split my tests in two the first is the one I really want then the second to try my
ISP as the easier option to help me learn and also breakdown my problems. I had some
success here.
Files used
in /etc/sysconfid/network-scripts
chat-ppp0
ifcfg-ppp0
ifup-ppp
in /etc/ppp
chap-secrets
ppp-secrets
1. I set up a simple chat script of 4 lines to connect which dials up and connects OK
then I get :-
13:50:33 bull chat[3782]: User Access Verification^M
13:50:33 bull chat[3782]: ^M
(gap of 32 seconds)
13:51:05 bull chat[3782]: Login:^M
13:51:05 bull chat[3782]: % Login: timeout expired!^M
13:51:17 bull chat[3782]: Login:
13:51:17 bull chat[3782]: alarm
13:51:17 bull chat[3782]: Failed
13:51:17 bull pppd[3771]: Connect script failed
13:51:17 bull pppd[3771]: Exit.
(disconnects after around 45 seconds)
If i add the login and password to chat script (just to see what happens)
15:33:35 bull chat[1563]: User Access Verification^M
15:33:35 bull chat[1563]: ^M
15:33:35 bull chat[1563]: Login: -- got it
15:33:35 bull chat[1563]: send (mylogin^M)
15:33:35 bull chat[1563]: expect (ord:)
15:33:35 bull chat[1563]: mylogin^M
15:33:35 bull chat[1563]: Password: -- got it
15:33:35 bull chat[1563]: send (mypass^M)
15:33:35 bull pppd[1558]: Serial connection established.
15:33:36 bull pppd[1558]: Using interface ppp0
15:33:36 bull pppd[1558]: Connect: ppp0 <--> /dev/modem
15:34:14 bull pppd[1558]: LCP: timeout sending Config-Requests
15:34:14 bull pppd[1558]: Connection terminated.
15:34:14 bull pppd[1558]: Exit.
The above failed to create /var/run/ppp-pp0.dev where 2a) succeeded.
I tried adding -d to the pppd line and a line in /etc/syslog.conf for pppd to
/var/log/pppd but this did not produce any more info.
chap-secrets contains
mylogin * mypass
Do I need more info from the dial up connection?
Does he need info about me?
2.
a. For the ISP (who claims to handle chap,pap and normal login) i tried.
ifup-ppp ifcfg-ppp0 with the chat script containing login and password.
This seems to connect and login OK, but when I unplug my ethernet connection I
cannot ping.
How can I make my ping, browser etc. use the dial up instead of eth0.
b. I tried then removing login and password from chat scripts and adding them to to
pap-secrets and setting PAPNAME to mylogin.
ifup-ppp ifcfg-ppp0 now connected but didn't login
It failed to create /var/run/ppp-pp0.dev where 2a) succeeded.
chat[2627]: ^M
chat[2627]:
last message repeated 23 times
chat[2627]: ** Service Provider **
ts=194.242.128.130;ns=194.242.128.1;^M
chat[2627]: ^M
chat[2627]: ^M
chat[2627]: Login:
chat[2627]: alarm
chat[2627]: Failed
(disconnects after around 45 seconds)
I suspect that this means it is not looking at pap-secrets. I tried using +pap
before I realised that this was not the correct thing to do.
If i do not specify +pap how does the server know whether to use chap-secrets or
pap-secrets (both exist) or is my server provider giving me bum info.
3. I also tried to use minicom to connect to my ISP then quit without resetting the
modem to try the ping but the ping failed as above and the modem disconnected anyway
after 45 seconds.
