Ubuntu Networking :: GPRS - LCP Terminated By Peer
Nov 20, 2010
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:
at+cops=?
+COPS: (2,"VodaCom-SA","VODA","65501"),(3,"MTN-SA","MTN","65510"),(3,"","","65502"),(3,"Cell C","C)
at+cops?
+COPS: 0,2,65501

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 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 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'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.

I have a Samsung phone (S3310) and I'm trying use it as a modem to access the net on 10.04. I set up a Mobile broadband connection (under network connections) and I'm pretty sure the settings are correct because it works on a Nokia phone with the same service provider.
When I plug in my Data Cable and set it to Samsung PC Studio mode, my phone isn't detected as a modem. I just tried wvdialconf and it says "No modem detected". I'm guessing that maybe I'm missing some drivers here. what I can do get the phone detected as a modem.

I am trying to connect my q75 micromax mobile with my computer as modem using wvdial. But I could not connect as modem. I insalled wvdial, gnome-ppp and mode switch through synaptic package manager.

I have two Desktops. Both running Fedora 9 and connected to each other with a crossover cable. I have a GPRS connection via a USB bluetooth Dongle. I can connect thru rfcomm on Kppp. Assigned static ip's 192.168.10.1/2 and can ping from one computer to the other. So far so good but now I want to share the internet connection between the two computers and run into a maze of gateways and DNS and iptables and am spinning around with no clues. Some of the things I do not understand are
1. What gateway does one assign when your computer directly connect to the internet through a GPRS and not through a NIC or router??
2. When I try to load the shared NFS folder, why does it say "could not load the location: internal error"?
3. Is there somewhere I could get a step-by step instruction??

I'm developing an application to monitorize the network interfaces plugged in my PC. I know that wireless interfaces are listed in /proc/net/dev, but I don't know how to identify a cellular NIC.Is there any virtual file in /proc that shows the cellular NICs in the system? Could I identify different cellular NICs looking at /dev/tty?

I need to setup my Sony Ericson C510 phone modem in Ubuntu linux the latest one that I have installed. When I connect my Phone using USB connection it doesnt show me the Dialog box where it says create new "Mobile Broadband Connection". I am not sure how can I configure my Tata Docomo GPRS Connection to use it with Ubuntu.
Here's one blog i came across which says:- Its wonderful to see people browsing in their mobile phones at work places and while they travel. Many Telecom companies provide cheap GPRS / EDGE based internet connectivity which can also be connected to a computer. Here, I will explain how to connect TATA Docomo Internet service in your Ubuntu machine.

I have a little bit of a prediciment with my Mobile Broadband dongle, even though I know I'm in a 3G area (Dongle Supports 3G connection) my internet still loads at the normal GPRS speeds max of 5kb/s. Is there anyway to change the speed of it or do I have to keep with GPRS at the moment?

I have an external hd attached to my one computer at home, use DynDNS to give it a static address, and can usually ssh into the machine fine. I ran update a few days ago and now have the much-aligned "connection reset by peer" error. I checked the machine and made sure everything was "normal;" e.g., checked ssh config for the port change (correct), doubled-checked ufw to make sure the port was open (it was), etc. I ran nmap on the machine and it said the port was open. This morning when I arrived at work, I ran nmap on my machine here where I've been unable to connect and its results were a little surprising: the port I specified at home and was demonstrated as open is not. WTF?

which cropped up today after no changes to the system: I can successfully ssh into my ubuntu 64-bit 9.10 machine (via OS X with iTerm), but after about 30 seconds, the connection drops with the message "Connection reset by peer Connection to xx.xx.xx.xx closed".
If I then try to immediately ssh back in I get: "Write failed: Broken pipe". If I try to immediately ping the machine instead, I cannot ping it until the ~10th try. Eventually I can log back in again, only to be kicked off after between 5 and 60 seconds. I called the network people and their are no known issue right now with networking. The networking on the ubuntu machine is otherwise fine, it seems. In the /var/log/auth.log file, it simple says:
Quote:
Feb 9 14:19:20 harriet sshd[4134]: Accepted password for xxx from xx.xx.xx.xx port 55105 ssh2
Feb 9 14:19:20 harriet sshd[4134]: pam_unix(sshd:session): session opened for user xxx by (uid=0)
Feb 9 14:19:28 harriet sshd[4046]: pam_unix(sshd:session): session closed for user xxx
The solution I come across to a similar problem is to add a "ClientAwakeInterval" number to sshdconfig, but this (as expected) doesn't fix my problem.

I want to configure socket timer to release socket(port) once the connection is terminated. Do we have something in Linux OS to configure this delay to release socket?.
Any command, link or man-page anything will be helpful.
I browsed a lot but unable to find it.

I am pragmatically trying to upload a list of files from my client machine to a proFTPd server I have running on Ubuntu. Every time I get several (around fifty) files into the transfer, I get the following error: Quote: Connection reset by peer: socket write error
I am able to remotely upload 25,000 small files of ~ 1K in size, but when I go to upload hundreds of 2-4 Mb files, I get a socket write error. Am I using up all available sockets before they can be released? If so, how do I release the sockets? If not, what does this error mean and why am I getting it?
