Re: unable to connect with internal modem under Ubuntu

Devon and list:
this thread was long and I believe that I solved it - sufficiently general saga worth being in archive.

Devon has an HSF modem in his Ubuntu 8.04 box.
He correctly installed the driver but could not achieve a connection.
I have the same modem on my RedHat modified (aka Scientific Linux) in my box. I met no problem getting connected first to my University then to Devon's ISP http://www.nocharge.com/ with S.L. I then loaded my old Ubuntu 7.10 Live CD, installed the driver (from the generic file, not the precompiled), from Linuxant. Either with wvdial or with the Ubuntu System->Administration->Network tool, I immediately got connected to my University but experienced the same rejection as observed by Devon with his ISP. I have no scruple disclosing the username, password and phone number of his ISP because they are publicly displayed on the Web page quoted above. The username was aptly chosen as "guest" by the ISP.

The debugging option of pppd (syslog) made me find out that the cause was a PAP rejection.

Lo and behold, the file /etc/ppp/pap-secrets on the Ubuntu 7.04 Live CD, and probably every Ubuntu distro, contains a block of restricted user id's to which dialling is denied. Of course my RedHat based system does not have that block.

Sure enough, "guest" is in the blacklist !!!

Devon: locate that line in /etc/ppp/pap-secrets , insert a # at the beginning to make it ignored by pppd, and let me know if you get connected, as I did. I am really eager to know that you too can now connect. I tried with the Ubuntu network manager above, not with wvdial, because Ubuntu sufficiently mocks Windows in hiding things and decides for the user what he wants to do without letting him ask, user assumed to be readily dumbed to the 200 % level by Microsoft. Simply, I never could find how to disable the Ethernet and Wifi interfaces under Ubuntu: you disable them, within up to 30 seconds they are back, forcing routes and DNS's which you do not want for the analog modem connection.
