CentOS 5 Networking :: WVDIAL Will Not Dial Alternative Number?
Apr 6, 2010
Using Centos 5.4 I've successfully set up pppd and wvdial to automatically dial out but I need wvdial to call an alternative number if the number is busy or dialout fails for some other reason and I cannot get this to work. I've gone back to basics and tried manually soliciting wvdial with a minimal wvdial.conf:
[Dialer ppp-client]
Password = secret
Modem = /dev/ttyS1
Phone = 11111111111
Phone1 = 22222222222

I have only a dial-up connection. I've been using the 32-bit version of WVDIAL and its associated programs in Karmic Koala for over a year. I recently finally got around to installing Maverick Meerkat on a different drive. The 64-bit version. I see that I need the 64-bit version of the modem software, and I haven't found it right away. Where can I get it? The programs required under 32-bit Karmic Koala:
libwvstreams4.6-base
libwvstreams4.6-extras
libuniconf4.6
wvdial
All of these had .deb filename extensions. Also, largely because I only have a slow dial-up connection, I don't have any updates for either Karmic Koala or Maverick Meerkat installed. If you happen to know that I absolutely need some particular update(s)

i've got a select based application that wants to support a large number of mostly idle connections. the code is java and works on windows, suse enterprise linux, mac os x. it does not work on centos 5.5 (32-bit, 2.6.18 kernel, 1G of memory).
i've read and followed the directions in various articles about tuning linux for large numbers of connections (including the C10K problem), and gotten the number of sockets up to 3200.
these didn't make any apparent difference:
[URL]
on windows, i can get up to around 78,000.
on suse enterprise linux (a few years ago), i got up to 90,000. that's where i got bored and stopped.
on my mac laptop with os x (snow leopard), i got up to 10,500.
i have used ulimit -n 10240
my current goal is 10k sockets.
the test is that i'm opening one socket at a time until it fails. when it fails, many of the sockets which have already been opened also fail, in one giant cascade. sounds like a buffer / memory problem.
each group of 64 sockets gets a thread to manage select calls for them. thus i'm only using around 61 threads total when it fails.

I post here wanting to know if it's Possible to run wvdial as soon as linux detects USB modem.I have already installed and done the setting for using wvdial. I can successfully use wvdial command to setup internet connection.But I have only 1 USB modem. When my wife wants to use it for her PC, she disconnects it from my linux machine.What I want to do now is... 1 that when I attatch the USB back to my linux, I'd want it to do "wvdial &" automatically.2 that when linux is rebooted, "wvdial &" done automatically as soon as it detects USB modem.

What I want to do is to share the internet connected to a computer with a telephone, over another telephone which is permanently connected to the pc.The thing is, that some guys found a way of making this on windows, in fact, I already set it up on xp and works like a charm, it involves configuring in a certain way the telephone, and to use 2 programs. One is CCProxy, which redirects the internet connection to the telephone, and another one, which updates the IP adress of the telephone connection to dyndns, so that I can put that adress on my second telephone as proxy, and this way, surf on the net through my home internet on the telephone anywhere. Tricky right?
Now, the thing is I don't like at all booting windows only for sharing internet with my telephone. So I want to do it in linux. I use Ubuntu and Puppy linux home.I tried setting up the connection to the modem with wvdial, and... I got connected! But hey, when I connect to the telephone, I lost my internet connection (main, cable based, the pc connection) :-S. I mean, somehow, the "active" connection for the browsers and all the internet programs is now the connection I have made with my telephone, which is plugged to the computer.Now my objective here is that NO CHANGE of active connections get done when I start the connection to the phone, and then, get a program like CCProxy, and a dyndns updater for sharing the internet connection on the pc, to the connection made on the telephone-modem wired to the computer.

I already had solved the problem [URL].. but after several yum updates it has appeared again. Within the script "/etc/ppp/ip-up" the sixth parameter isn't provided. But the sixth parameter should be "ppp0" (in this case). The script sets it into the variable $LOGDEVICE and passes it as first parameter to annother script. Successfully I had patched "/etc/ppp/ip-up". I would like to report a bug but I'm not sure if it is a wvdial or a ppp/pppd or a Fedora 14 bug.
Now (after several yum patch updates) my patched /etc/ppp/ip-up doesn't help anymore. The registration at the mobile phone provider seems to be ok but the internet connection isn't initialized.
According the man pages wvdial starts ppp or pppd and one of them seems to call /etc/ppp/ip-up. At which point in the subprocessed scripts (under /etc/sysconfig/network-scripts/) I didn't find out yet.

My resolv.conf states:
No nameservers found; Try putting DNS servers into your ifcfg files in /etc/sysconfig/network-scripts like so: [...]
After running wvdial. I suppose I have to create a file ifcfg-ppp0, but what does it have to contain in order to automatically grep the DNS servers from wvdial?
In Ubuntu, it works just fine, just that I don't have an Ubuntu installation anymore.

I use wvdial and a 3G modem to connect to the network. On the same host I also run bind9 which is authorative for my local network.The problem is that when wvdial connects, it overwrites /etc/resolv.conf, which means that DNS lookups on that host no longer get made to localhost (as specified by the original resolv.conf file) and end up at the local instance of bind which is authorative for in-house hostnames, but end up with the ISP who doesn't know my in-house host names.The local DNS forwards to the ISP, so the ISP's DNS'es are not required in resolv.conf.How can I prevent wvdial from overwriting /etc/resolv.conf?Removing write privileges from /etc/resolv.conf did not work.

1) I have micromax 372g usb modem(3g).. but it is not being connected ubuntu 10.10
2) I suppose my device is being recognized and I tried this method [URL] but when I tried to install, it said that package missing for wvdial.
What should I do. Where can I get this package and how can I install it (with no dependany check). My life is extremely difficult without internet on ubuntu, I am ready to give any other information that u need. I have ubuntu 10.10 maverick dual boot with windows. And yes take into consideration that I don't have internet on ubuntu. So provide me full detail how to install it from other media and commands to execute them.

I've been running 8.04 Hardy since its first release, and was hoping to deal with its loss of support by going to 8.10 but learned that it has already been dropped.
So I'm back to installing 10.04 - and up against the bizarre choice to drop dial-up networking! Fortunately, I have my 8.04 machine still live, and I've researched it extensively without success.
The best summary of what I've done follows this post I found online:
-----QUOTE-----
I read many threads about dialup, including those on this forum; made sure to get an external hw modem [USRobotics 5637 USB, advertised as controller-based and tested to work in Linux], to avoid the softmodem/winmodem problem.
Using the 10.04 LiveCD, I installed the four .deb packages that are in poolmainwwvdial and in poolmainwwvstreams.
Now I'm stuck because I get errors when I try command line stuff, errors like "cannot open /dev/modem" and "can't find /dev/modem in /etc/fstab or /etc/mtab"
I'm confused; I've read so many threads with so much different info that I can't sort it out. Maybe I'm following info that applied to earlier versions of Ubuntu. Every error I try to fix leads to more errors. Can someone suggest a constrained, step-by-step procedure to ensure I've mounted the modem, added myself to whatever groups, and whatever else I need to do?
I know there's no wizard to make it simple, but is there a checklist or something to help me sort this out? I have the ISP info, DNS primary+secondary server numbers, phone numbers, etc. Is there a UI/graphical path, instead of command line? Had no idea this would be so difficult.

Ive been looking, and even tho dial up stinks, its better than nothing for me out here in the woods. I downloaded gnome-ppp. This should work for a linux friendly serial modem (US Robotics 9637 USB external)which is on the way.

On a fully updated Ubuntu 9.04 system, I had successfully configured wvdial to connect using a USB modem ("Update" brand) with an ID of 067b:0611 (uses the pl2303 driver module). In considering an upgrade to Ubuntu 9.10, I tried a LiveCD and was unable to connect using wvdial. However, because I had made the CD a couple months before, I went ahead with the upgrade (via the internet; not a fresh install) in the hopes that it would end up working or I would be able to find a solution for it.
The Problem: The upgrade was a success as far as I could tell, but when I tried to connect to the internet with wvdial, I was not able to. I checked the wvdial.conf settings to make sure they were the same as before, added some new ones I thought it might need, unplugged the modem and replugged it, restarted my system, etc., but all to no avail. Whenever I would try to run wvdial to connect, I would get the following output:
Code:
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
[code]....
This was different than the output I used to get with wvdial, but when I went over to my browser (Firefox) the internet worked fine. I'm assuming my email client and other things will work okay as well, but have not tested them as of yet.
A final touch I did to make connecting a bit less 'painful' was to right-click on the panel (at the top of the default Ubuntu screen), and click on 'Add to Panel'. Then I selected 'Custom Application Launcher', chose 'Application in Terminal' for 'Type', gave the launcher a name, pasted in that 'horrifically' long command line above, gave a brief description in the 'comment' box, then pressed 'OK'. Voila! I now have a launcher on my panel that with a single-click will bring up a terminal screen where I enter my sudo password and it connects. Then when I want to disconnect I just go back to that terminal, press Ctrl+C, which promptly disconnects me and causes the terminal to vanish into thin air.
Now, I don't know enough about this stuff to know why this command worked and wvdial didn't, but if you know, feel free to post a reply. Or if you'd like to see what settings I had for wvdial that worked in 9.04 but not in 9.10, let me know. Or if you think it's worth checking to see if this should be posted as a bug in either wvdial or Ubuntu, you can mention that as well.

I'm having trouble getting online, and therefore getting software, codecs etc, (I'm using another computer for this post) because the only option I have to connect to the web is through 56k dial-up modem, and this is apparently akward with ubuntu. I'm currently trying to work out how to get Ubuntu to recognize my modem. I have over-written Vista, which was previously on my laptop, although I did make recovery discs (though I really don't want to have to use them).
This is making it difficult for me to even find the model of my modem (it would involve reinstalling Vista and checking for the device under device manager, or Vista equivalent).I was advised to download the "Official Ubuntu documentation", and that this had a 'how to' section regarding dial-up modems. I downloaded it and searched it and found nothing as such. I also have downloaded the Ubuntu pocket guide and found nothing on the topic in it either.I can get online (via dial-up) on my XP machine, and also have USB storage sticks.

I'm using an external Huawei CDMA fixed wireless terminal (phone + dial-up modem). It connects to my PC via a USB port. Actually my PC recognizes it (after driver installation) as "TIUMP Serial Port". I guess the driver is a kind of USB adapter for a serial port.
I can't get it to work in ubuntu 9.10. I ran wvdial (after installing dependencies and wvdial package) and it doesn't recognize my device as a modem. Is there any solution to this problem? Without solving it, I won't be able to go online from ubuntu.
