Fedora Networking :: 3G USB Modem - LCP Terminated By Peer
Sep 7, 2009
I recently upgraded to Fedora 11, and am having an issue with the USB modem (Novatel USB720) disconnecting almost immediately after it is connected. Sometimes it disconnects 30 seconds after it is connected, sometimes 2-3 minutes. And other times it stays connected for hours without a problem. I know the card is good as it works using Verizon Connection Manager software under Windows and never had this problem.
And, I am able to get to the Internet while it is connected, so it is passing traffic OK. I'm using the NetworkManager to connect the "Auto Mobile Broadband" connection. I've seen other posts on this very same issue, and I verified that pppd is called using the "lcp-echo-failure 0" and "lcp-echo-interval 0" options. But it seems that when it does disconnect, in /var/log/messages it says "LCP terminated by peer".
Below is an example of /var/log/messages where we can connect, then it immediately disconnects.

I am trying to get pppd/chat working with an internal Wavecom modem, but PPP terminates with message "LCP terminated by peer". But, same pppd/chat configuration is working on my own Linux OS with Huawei 3G modem. I tried several options to get it working, but no luck. The problem is happening during the PPP negotiation with the Modem:
rcvd [LCP TermReq id=0x2] LCP terminated by peer
But this only mean that there was a failure during PPP setup between Linux and the Modem. I tested the modem with manual AT commands via minicom to further investigate to problem, but could not even activate the PDP context:
Modem is registered and attached to Vodacom's network:
I have been using GPRS on a Nokia 6230 on PCL 2009 for months, no problems. Got the C5212 2 days back. First, it would not connect using the old wvdial.conf file (the modem was detected on the same ttyacm1 port), throwing up an error I don't recall now. Then I did a wvdialconf, and edited the resulting file, and this time I got an error "Voice line detected".
The phone came with the windows software, so tried getting online on a Win install. The phone connected, but the procedure involved disconnecting the phone (as described by the software itself). Assuming this "disconnection" could be a reason for wvdial to fail, I tried again on Linux. This time I could get online, without a hitch.
Yesterday, I abruptly started facing a new problem "LCD Terminated by Peer". I had used the phone error free for more than 2 hours. Then I disconnected and plugged it again, and voila the error! I have looked at many sites and their solutions. None of them seem to change this situation. The most popular tip is to comment out all lcp related lines in the /ppp/options file. I am using wvdial and kpp, and my options file did not have those lines in the first place.
I know I'm missing something absolutely basic here but when I search the forums for filesharing I only seem to get info referring to Windows filesharing/SAMBA etc.
We have 3 Ubuntu machines at home and a printer on a Windows machine. How can we best fileshare:
1) between Ubuntu machines 2) reliably between Ubuntu and the Windows machine
Printing across the network is ok except for the Karmic NBR machines but that's another thread.
When I plug in my iPhone to my 10.04 machine, it's recognized. I can always drag music from the iPhone to the Music collection in Rhythmbox, but 9 times out of 10 dragging the other ways gives me this error:
"Error while getting peer-to-peer dbus connection: The name :1.219 was not provided by any .service files"
I am using Ubuntu 10.4 LTS and Samba3.4.7.I have read a lot of posts and different web pages on setting up Samba on a Peer-to-Peer network with Windows XP but just cant make it work. I can see the Guest account in XP My Network Places but cant access the folder when I click on it.Network not accessible or you dont have permission. I can PING both ways ok. I have Firestarter turned OFF and I dont have any third party firewall on XP.
This is my samba config file:
[global] netbios name = dolphin server string = Ubuntu workgroup = WATERLILLY - same as XP
I've happily been using rdesktop to access my MS Vista desktop from Ubuntu (Hardy) for a few months until a couple of days ago when it stopped working. Now if I try connecting I get the following:
[Code]....
I don't believe anything's changed on the client (Ubuntu) side. The Vista box is occasionally connected to a corporate intranet via VPN and it was after such a session that rdesktop stopped working, so perhaps a Windows group policy was modified during the session. I've checked the basics - can ping 10.1.1.2 from Ubuntu, can access port 3389. Have deleted ~/.rdesktop and ~/.tsclient.
Digging around the Vista client I noticed in Control Panel > System Properties > Remote that in the Remote Desktop sub-panel the Allow connections only from computers running Remote Desktop with Network Level Authentication setting is enabled and that the other two are greyed out. Now, I don't know whether this setting has been changed but I suspect that it might be the problem.
Unfortunately, I don't know enough about Windows to know how or even whether I can change this setting to Allow connections from computers running any version of Remote Desktop (less secure) I've poked around the group policy editor (gpedit.msc) but no joy.
find and install modem driver for the Alcatel X200 USB modem?
I've been all over the internet trying to locate Linux drivers but no success. Alcatel's website says is not supported, only in Windows. I'm sure there's gotta be a way to use the X200 in Linux.
i'm running Kubuntu karmic and i've been using a 3G Huawei E1552 modem to connect to the internet, everything was going well when suddenly my modem stopped working. I've tried reconfiguring everything, i even reinstalled kubuntu from scratch with no success.Here's a part of my /var/log/debug

My organization just moved to using a zscaler proxy system. Basically, I have to use a .pac file in Firefox to get onto the proxy, which directs me to a series of two Flash pages, one to input my username, one for the password. After reading through the .pac file, I was able to get some command-line things to work by specifying the proxy given at the end. However, this server uses an SSL certificate that is not emitted by an authority, but rather directly by our organization. In Firefox, I had to import this certificate to enable https:// browsing.
Is there any way to "import" this certificate so that yum can use it? Because yum freezes with the error: Code: Could not get metalink [URL] error was 14: Peer cert cannot be verified or peer cert invalid
I have installed the KDE spin and am liking it so far. Except for the fact that I cannot get onto the internet. I rely on this ZTE USB wireless modem for internet and that just would not get recognized in Fedora. Plus, my Windows installation is down and I would love to keep it that way if at all possible.
I have followed a few instructions on this particular problem. I have modified the menu.lst file to account for the usbmodserial and product. The usb_modeswitch program has also been installed and the usb_modeswitch.conf file has been edited with the values I got from the 'lsusb' command's output.
But the curious thing is that when I actually execute the usb_modeswitch command, I get a message saying that there are no drivers for the ZTE device. Which means that I cannot go onto the wvdialconf part of it at all. Basically at this point I dont have a modem, according to Fedora. But it does get recognized as a ZTE device. That tells me that there is something right about what I have done so far and may only need to do a few tweaks here and there.
PS - I am based out of India and this is a Tata Indicom Photon (NOT Photon Plus) connection for which I have a USB device which acts as a modem.
i have modem HSPDA ( prolink PHS 100) but i don't know how to use in linux. I already to set password,user name and etc. in wvdial. but it still can't to connect to internet.
When I use Ubuntu, my DSL modem correctly gets the hostname I call my computer "mertensia", but I'm having issues with Fedora. Yet, when I look at the name assigned by the modem (using URL... in a web browser),I need the PC Name to be mertensia, because otherwise it will complicate how I ssh immensely.
My brother installed Fedora 8 on my 2004 Dell Inspiron 1000 laptop with a 56k MDC modem. I cannot figure out how to get the dial modem to work! Modem Device?, Baud Rate?, Flow Control?, Modem Volume?
For F10 patched. I'm in Honduras. The local cell / Internet provider that covers Guatamala, Honduras, El Salvador, uses an HSDPA modem marked "GBC" and is also known as the "China Bird". It's a black usb stick that looks identical to the option unit, but its definitely not an option modem.
lsusb lists it as 1c9e:1001 with no text after it. It automounts as a disk drive with typical Windows software on it. Nothing ever shows up in /dev/ttyUSB*, as I believe the disk mount causes it to not try mounting it as a modem. Dismounting it also does no good.
I have a creative modem blaster V.92 which I know works because I have used it on windows and ubuntu how ever I am having some problems with F11 it sounds like its dialing okay and the box pops up that says please wait when I try to connect via the network manager thing but thats all it does the box never goes away and I've looked at the modem lights thing I added to my panel and it says its not sending or receiving anything and firefox doesnt work so I am not sure what I am doing wrong here.
I got an error with the default settings so I switched the device to ttys0 and set the baudrate according to what wvdialconf said was okay which also wont connect for some reason it hangs too.. I am confused here. Has anyone successfully set up a dial up connection in fedora 11
I have F9, F10, F11 and F12 installed along with WinXP on my desktop PC. I connect to the internet thru 56K dialup modem (USR-5610B). The earlier versions of Fedora, F9, F10 and F11, all can connect via dialup modem.
My F12 installation is augmented with the following rpms - kudzu-1.2.86.2.i686, libwvstreams-4.6-5.fc12.i686 and wvdial-1.60.10.fc12.i686 (and the rpm for USR-5610B modem)
Network Configuration GUI shows ppp0 (Modem) in the Common Active Profile
However, ppp0 does NOT show up in the Network Device Control GUI, AND ACTIVATE and DEACTIVATE buttons are GREYED-OUT.
The problem is that when I connect my phone to my machine FC11 x64 via USB and use the phone as a modem NetworkManager does not recognise the phone as a modem. The phone works well on my laptop which is FC11 32bit system, NetworkManager detects it and sets it up as eth2 and away I go, no problems at all. I would like to ask the community how can I go fault finding to find out why it does not work. #lsusb shows that the modem is being detected by the system but beyond this I don't know where to look and get things going.
if i have Fedora 13 installed on a desktop and on a laptop, can i organize so that both machines use the same dsl connection? I have an external DSL modem that is currently connected to my PC via an ethernet cable. When I want to use my my laptop I usually unplug the dsl connection from my computer and plug it into my lap top. is there some way i can have it connected to both?
Ive got two connections, one is the eth0, that is the LAN connection to the DSL modem (192.168.1.1) and the other is the DSL connection that I connect to use the internet. Now I can only connect to one of the two at a time, so when I'm connected to the internet, I am not able to access 192.168.1.1. How do I use the two simultaneously?
My girlfriend's xp machine has decided to refuse to boot and as a consequence have told her I can install fedora for all her computing needs (facebook and errrrrrrm facebook)
Problem, she's got this strange usb modem, a thomson speedtouch 330 which when plugged into my laptop is listed in lsusb and lsmod which suggest to me the module/driver is built into the kernel, but does not at present work, I'd hate to admit defeat and reinstall xp.
My EVDO (Mass storage cum Modem device) like USB Modems not working on Linux-2.6.10 kernel.I used usb_modeswitch-1.0.5.tar.bz2 package on Linux to flip from mass storage device to modem
My USB-modem and my freerunner phone is no longer recognized by fedora. Last time this happened I just reinstalld Fedora because I had no id�a what caused the problem. But now I recognized that virtualbox was the last package I installed before the problem occured. I tried to uninstall virutalbox but the problem remained. Is there a way to reset all the network settings without reinstalling fedora?
