Dear Gopu, I had sent an introductory e-mail addressed to you on Jan 4 (link through: linux.org/groups/index), but haven't received a response yet. A copy of this is being marked to John Ranjith Paul, who also figures on the list, and also to linmodems in case they can help directly. I am hesitant to register with the "linuxexperts" group, since I am altogether a novice and may not be active once my immediate problem is solved I have made some progress with configuring the modem on my Dell Inspiron 1520 laptop. Details are described below. I am located in Adyar, Chennai, and have a BSNL NetOne dial-up account (through phone no: 24452810), which is presently being used with an old desktop running Windows 98. I wish to connect my laptop (which has now been loaded with Ubuntu 8.04.1) for accessing internet henceforth. Following the instructions in the Ubuntu help files, I downloaded ScanModem.gz from the LinModem website and ran it on the laptop to generate various files specific to my system. Of these the ModemData.txt was sent to discuss@xxxxxxxxxxxx as advised, and I received further instructions by e-mail (full text is given below in QUOTE-UNQUOTE form). I was then able to download the linuxant hsf modem and the alsa driver package as instructed and ran the given commands. Unzip hsfmodem... was OK. On running "sudo dpkg ..." I got the error message mentioning dependency, alsa driver ... not installed. The downloaded file was "alsa-driver-linuxant_1.0.19git20081204_all.deb" (4184 kbytes) When I tried the "sudo alsa* -i hsf.deb" command, the response was "COMMAND NOT FOUND", and I don't know how to proceed from here. The instruction mentioned "with root/adm permission" which I didn't understand, so maybe I have to prefix some command. I would be grateful for any advice on how to go on from here. Hope I don't run into further problems. One other question -- does a dial-up connection require a DNS number? The Ubuntu instructions mention it, but the ISP (BSNL) informed me that dial-up has a dynamic IP address with no specific DNS. Thanking you, =Thomas Tharu= >>>> Full text of e-mail advice received from Marvin Stodolsky, Linmodem.org, dated 6 Jan 09:- QUOTE >>>> Thomas, From http://www.linuxant.com/drivers/hsf/full/downloads-ubuntu-x86.php download hsfmodem_7.80.02.01full_k2.6.24_19_generic_ubuntu_i386.deb.zip Under Linux unpack with: $ unzip hsfmodem*.zip Then install with: $ sudo dpkg -i hsfmodem*.deb Subsequently, the modem should be found with $ sudo wvdialconf /etc/wvdial.conf Edit in your personal information with: $ sudo gedit /etc/wvdial.conf and try dialing out with: $ sudo wvdial. See DOCs/Testing.txt for details. Support for Conexant chips hosted on High Definition Audio cards may require installation of additional packages, one of the alsa-driver-linuxant packages on http://www.linuxant.com/alsa-driver/ At the same time download the alsa-driver-1.0.17-1.patch , in case it prove to be later needed. During the hsfmodem install, there will be a message if there is necessary installation of alsa-driver-linuxant The installation command for a .deb suffic packages is, with root/adm permission: sudo alsa* -i hsf*.deb while for .rpm suffix it is, with: rpm -i hsf*.rpm There may a message that "Dependencies" are not satisfied. In this case the Ubuntu/Debian packages to be installed are linux-libc-dev & libc6-dev. Package names may be different for other Linuxes. If not on your install CD, these packages can be searched for at http://packages.ubuntu.com. After download, they can be coinstalled with: sudo dpkg -i li*.deb Again try the alsa-driver-linuxant There may be a message that the patch must be applied. In this case get the ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.17.tar.bz2 Under Linux, this package is unpacked with: $ tar jxf alsa*.tar.bz2 Next the patch is applied with: $ patch -p0 < alsa-driver-1.0.17-1.patch See http://linmodems.technion.ac.il/bigarch/archive-eighth/msg00838.html for details on compiling and installing replacement snd-hda-intel + its dependent drivers. After the installation is completed, rerun the hsfmodem installation. Reboot and try to detect the modem with Root permission: sudo wvdialconf /etc/wvdial.conf Read DOCs/Conexant.txt <<<< UNQUOTE
