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.
