Newbie Help Please, Hi guys I,m still unable to connect to the dialup service despite all efforts & ISP providor ( They will NOT assist because I am using Linux only if I use Windows). If you can offer any advice on what may be the problem from* the error message I would be most grateful. Please see the* attached Screen dump of the attempted initialising of the dial up connection Thank You Regards Rob

It has been a long time since setting up a dialup, and there could be a couple of things happening here.

1. The dialer utility MOST LIKELY needs to be started by root. If doing this as root fixes the problem the next issue shouldn't be relevent, but MAY affect second logins and starting the dialer not as root.

2. The dialer may be running setuid to a dialer utility, and needs to be configured first.
According to the documentation for WvDial, the file /etc/wvdial.conf should exist - this file ought to have the
phone number, the username, and the password to use as well as the choice of authenticator (the default may be
wrong).

In addition the file /etc/ppp/pap-secrets is used to store the password so the dialer may be started by a user
without root (the setuid/setgid on the dialer should handle that) - but the file may be owned by root and not
the dialer account.

You will have to refer to the manpage on wvdial (both "man wvdial" and "man wvdial.conf") to see what the contents of the /etc/wvdial.conf should be (my file is empty, but I'm also not using dialup).

did you add user to dip group?
What isp are you using?
maybe this will help: http://dedoimedo.com/computers/dialup.html

See warnings on this page maybe. http://manpages.ubuntu.com/manpages/.../wvdial.1.html

Oh,... Besides jefro's excellent suggestion to look at the wvdial manpage,... You should also consider this; Many telephone modems are "Winmodems,"... That is, the modem lacks a DSP and relies on firmware (and the CPU) to do that job. What you want is a "true" modem with a DSP (Digital Signal Processor)... It's been years for me since using dial-up, but I recall I had to get an external modem with a DSP (it connected to the computer through an RS-232 port,... if that tells you anything about how long ago it was). Many of the old "Winmodems" were eventually made to work in Linux,... Many were not.

Thanx for your assistance that file /etc/wvdial.conf does not exist. /etc does but NO Wvdial.config

Are you using a GUI dialer (eg gnome-ppp)? That may explain why the default config file (/etc/wvdial.conf) is not present. The graphical utility you are using will have a similar config file in a different location, and call wvdial using that config file.

Anyway, it does look like it is failing to establish the ppp session because it fails to authenticate, (likely for the reasons jpollard and colorpurple indicated already).
Check that the user is in the appropriate group for access. I think that when you sort that, authentication should complete with no further issues.

Check the permissions of /etc/ppp/pap-secrets and /etc/ppp/chap-secrets too

Who it is your dial-up provider? If it is netzero, the default linux dialers will not work, but there is a work around.

I think that's the thing I'm using lots of small pins & part of the reason to use this type of desktop PC. The modem seems to connect & handshake but immediately drops out with no connection. I am embarrassed to have to resort to attempts to use dial up as a means of connecting to the internet, however such is the availability of services in Australia for those that live outside of a major city. To add insult to injury i live on a property with a paved road approx 20 kms from a major town with the fiber optic cable less than 20 mtrs from my back door &have No access to the internet other than a VERY poor over subscribed satellite service. Connection to the internet would be quicker via dialup. How sad a state of affairs is that but that is the best available option..

Here in Australia it is DoDo. There are very limited dial up service providors available.Thanx again

I don't think you would have gotten an AT at all if it were an unsupported modem. Even winmodems are somewhat supported. I think your assessment of the fault is correct.

Think you need to look at a few solutions. One being if this pap-secrets and chap-secrets. Some web pages suggest putting in your info to them first.

It is failing on pap/chap.

Hi Rob

Further to jefro's excellent advice (which I also believe should get you a working dialup connection), you can actually use 'wvdial' itself to test and get connected from a terminal window. The 'wvdialconf' utility will detect your modem and create a basic /etc/wvdial.conf file.

Once that's done you can edit the file as root using your favourite editor, entering your phone number and authentication credentials.
For example, a basic working configuration might look something like this
You modem might be different to the example above, but wvdialconf should take care of getting that right. Here you can see that you'd add your phone number, username and password in the lines shown.

When done with editing, try dialling with
It may take a bit of further tweaking to get connected, but the wvdial output should reveal what is needed.

I can assure you that the situation you're facing is like that in many rural and even semi-rural areas of NZ, and in the USA from what I've read online from time to time. Do you have mobile phone coverage in your area? Is 3G/4G access an option? I know that the data is often capped in these situations, but better than dial-up in some use cases.

In any case, I am confident that we can get your dial-up connection working. You're so close!

Thanx for all your help No 2G 3G or 4G Fixed Wireless or ADSL available. Addition to Sat service expected March 2016, however they cant forsee how long it will be before they will be able to change me over.Thanx again Regards Rob

Thanx Ferrari I can get into the /etc/wvdial.conf ( Someone told me to use sudo nemo PW change to the file & enter edit. I can do this but how do I make it save the edit please ? It does not seem to save the edit entry. Regards Rob. P.S. I am removing the semi colons & justifying it all to the left. ( I think this is right) Appreciate your assistance Rob
