    Yes, I did read most of the Ubuntu wiki. I tried the adduser command and my user already belongs to both the dip and dialout groups. Connections through pon and the network gui both die out after the handshake. The wvdial, however, is the one having mixed success (working for a few seconds).

     

    I think that I may have found the issue. I checked the DNS addresses with "cat /etc/resolv.conf" immediately after connecting (when it's working) and got the DNS addresses listed by my provider. A few seconds later (when I can't access web pages, but it's still connected) I checked again and found them replaced by 192.168.123.254.

     

    I'm not a network spe[censored]t, but isn't the 192 a home ip address range? Perhapse the network is trying to but in on the modem session, messing with the config file...

     

    I tried manually changing the /etc/resolv.conf but it switched back to the 192 address after a few seconds. Also the route command had two default listings, one ppp0 and the other ethernet (though I only spotted this issue once).

     

    Thus, I'm wondering if there's a way to set the DNS and keep it from being tweaked. Would chmod be a good idea? While I'd like to give Ubuntu a try, if this doesn't start working soon I'm throwing in the towl and going back to Fedora.

    I've been testing to what extent the connection works and doesn't... and its a bit odd.

     

    Of roughly seven dial attempts with wvdial two were successful (able to load a web page). The first allowed me to go to any site for about a minute. After this I could make google searches and access a gmail account. However, any trying to access any search result would time out.

     

    The second attempt again allowed me to travel to web pages for around a minute. However, "ping 4.2.2.2" and "dig www.google.com" both failed. After this I couldn't access any web pages.

     

    The gateway seems to be correct (ppp0 when connnected), and the DNS addresses in /etc/ppp/resolv.conf are definitely being set by the ISP (and since it works in Windows, I guess they're valid addresses).

    The modem has a serial connection. Again, this modem works under Fedora 4 and 5, so it seems like the problem mentioned in the post probably wasn't a mechanical issue.

     

    What does "adduser <user name> dip" do? Is this something I should try? I searched the man page for adduser and couldn't figure out what the 'dip' is for.

    I just switched to Ubuntu and it has the exact same problem. I determined that the point at which the pon command started partly working was when adding the DNS entries to /etc/resolv.conf. However, it still only allows a brief connection (and doesn't allow Synaptic or apt-get to work at all). Any ideas would be appreciated. -Damian

    I've decided to switch to Ubuntu to see if it solves the problem. I haven't spotted many cries for help from the diminishing modem using community so whatever's going wrong is probably a subtle issue with Xubuntu. Thanks, though for all the help.

    I've made several changes and had mixed success (trying wvdial after each step). A friend of mine pointed out DialupModemHowto. It suggested adding 'replacedefaultroute' to the end of /etc/ppp/options. I also added both the DNS changes suggested by Wilhelmus. None of these seemed to change the output of the wvdial command, nor did it make the connection work.

     

    However, when I tried pon again I got a connection that allowed me to access web pages. Before breaking out the champaign I tried Synaptic to get firestarter and the modem lights component. However, Synaptic failed to connect to the repositories. I also closed Synaptic and tried 'sudo apt-get update' which failed to download anything. After a few minutes the browser connection stopped working as well. I'm about to go on a trip for the weekend so it looks like any further tweaks will need to wait until later. Cest la vi.

    I'm fairly certain this is a set part of the script. When trying to connect there were several failed attempts where it said different things. wvdial seems to be very good at giving verbose output and specifying if anything goes wrong. -Damian

    Thanks. With the wvdial command I was able to get a sustained connection. However, like pon it didn't allow a browser or apt-get to function. Below is the output... sorry that it's a bit long. The termination signal near the end was to disconnect after I found it wan't working (it's not an errror). Any ideas where to go from here?

    Hi. I've recently installed Xubuntu (Dapper) and run across a rather crippling issue- I can't get on-line. Xubuntu detects my external 56k modem, it connects (making the handshaking sound), then hangs up once the connection is established. The modem works under Fedora Core 5 and Windows 2000. I've been working on this for a couple of days and I'm totally at a loss.

     

    Lurking on forums, I found one thread with a similar issue back in 2004. A person mentioned that the solution was to "simply type apt-get gnome-ppp". The problem? I need an Internet connection to get an Internet connection. I can't simply get gnome-ppp and copy it over because it includes about ten dependencies- each of which have dependencies of their own. Even if I could, there's no certainty that it would fix the problem.

     

    I tried to connect through a terminal via the pppconfig then pon commands. This created a lasting connection (once) but didn't allow any internet activity (either though a browser or apt-get). Does anyone have any ideas of things to try? Thanks. -Damian

    Thanks for the reply. I've re-installed Fedora, again installing grub to hda (and again it booted directly into Windows). I followed the instructions here, using the Fedora rescue disk and entering:

    chroot /mnt/sysimage

    grub-install /dev/hda

     

    Like that thread, I got the error saying "/dev/hdb1 does not have any corresponding BIOS drive." Unfortunately, it doesn't look like a solution was found. This system is expendable, so if you have any ideas, there's not much to loose.

    Hi. I'm trying to make a dual boot system with Windows 2000 on hda and Fedora Core 5 on hdb. After reading several posts by danleff I've been able to get a system that can boot into either Windows or Linux depending on the bios. However, a problem's popped up with grub, and being new to Linux I'm not sure what to do.

     

    I first installed a fresh copy of Windows 2000 on hda, and formatted a 2GB section in FAT32 for transfers between Linux and Windows. I then installed Fedora Core 5 on hdb, keeping the default installation settings for the boot loader (placing it on hda). After restarting it skipped the grub splash and booted directly into Windows. I swapped the bios settings to boot from the slave drive and as expected, it said "No Operating System Detected". I read that Norton has a "Turn Back" feature that hooks the MBR and prevents changes. However, looking over the settings of my virus protection (AVG), I'm not spotting anything that looks like that sort of feature.

     

    After reading some posts I decided to place grub in the MBR of hdb instead to both preserve the Windows boot loader, and hopefully fix the problem. I re-installed Fedora Core 5, this time telling grub to be placed on hdb and clicking "Change Drive Order", making the slave drive first.

     

    Now if the bios has hda first it boots directly into Windows, and grub if it's hdb. In grub I'm able to start Fedor Core 5, but if I select windows it says:

    Booting 'Windows'

     

    rootnoverify (hd1,0)

    chainloader +1

     

    Then sits there. If switching the bios confused the boot loader, wouldn't both Linux and Windows stop working? Any idea what I should do next?
