I use libpcap to write a program to detect network device in Ubuntu but not sucess. The result is no suitable device found. How many reasons are there for that? The code i used is the main user page.
[code]
#define HAVE_REMOTE
#define WPCAP
#include <pcap.h>
#include <stdlib.h>
#include <sys/socket.h>

I am trying to install Libpcap version 1.0.0 on Fedora 9. During 'make, i get the following error:

I am currently using fedora 11 kernel 2.6.29 version, i wanted to write device driver for usb to detect my own device. My project is radio with computer. My fm radio get connected to usb port so i need to write h/w interfacing program.

I open the Network Device Control to activate it but there is no network ports in Network Device Control. It is empty.It looks like the system recognize the card and loaded correct driver.

View 1 Replies View RelatedSo I bought an eMachine e250 from a friend of mine, and installed Backtrack on it. That worked fine, until I realised that I didn't like KDE, and decided to get the gnome-based Gnacktrack (based on Ubuntu 10.10, so I'm fairly sure they work the same). I also have a harddrive from an old laptop that I've scrapped with Ubuntu 10.4 that I run in the laptop, and fpr some bizzare reason, neither operating system is able to detect the wireless card. It worked fine with Backtrack (based on Noppix I believe), and I'm curious as to why the wireless card hates Ubuntu so much. I know that it's unable to detect the wireless card because on start-up it says "Unable to detect WMID device". I even added the wireless card from my scrapped laptop to the laptop, and that NIC was detected just fine. (though I can't use it because the antenna won't reach the slot for the secondary NIC)

View 2 Replies View RelatedI have a pair of special radio-devices which support SNMP, but the problem is, that if I snmpwalk those devices, I only see few generic values(sysContact, sysDescr, sysServices etc) and nothing else. Most likely I need MIB files so NMS could know what values can be asked from the radio devices? If yes, is there a possibility to get all the OID's device supports without MIB files as those devices have been out or production for years?
View 2 Replies View RelatedI have installed WICD on Debian . I can now access a new a Network Manager screen, which did not exist before, but it does not display/detect any wireless networks. It is like dead. Before installing WICD I did at least have a wireless WPE encrypted network, which was detected, although it often disconnected for no known reasons. Now even that Network has gone and I can't go on line. Can anybody help here? How can I configure the WICDNetwork Manager to detect an existing network or create a new one? In the latter case, would I have to reconfigure the Router settings to setup/connect to a network in Debian? May be I have to do this, because Tor/Vidalia changes my IP address and so my Network Adapter ( Linksys) can no longer connect to the router.
Also, when trying to follow troubleshooting leads in this connection, the Terminal screen on Debian ( CMD) would often return a PERMISSIONS DENIED message.

I have a RIPLinux/Tinycore live USB disk that automatically needs to run a script that is stored on the same USB drive but not part of the RIPLinux/Tinycore image.

I've just fully installed Ubuntu on my laptop. I had it running as a secondary operating system and have switched over. Now, however, I'm having all sorts of incredibly frustrating problems, one of which being that it won't detect the wireless networks around me!
how I can get the network manager to automatically detect wireless networks in range, this whole process has become very frustrating.
I installed ZTE MF 626 modem in my F10 with kernel 2.6.27.12-170, i run usb_modeswitch and so far things happened normally. Watching through /var/log/messages it says that F10 detects two port device for this modem: ttyUSB1 and ttyUSB2, and in the sequence it disable port ttyUSB1 BUT Network Manager still set this port.I mean, when i connect via wvdial appointing to ttyUSB2 i get connection, but Network Manager fails to do it appointing to ttyUSB1. How to change device port in Network Manager?

I can connect within the LAN but not outside. If I execute tcpdump while the tun0 is up, I first receive the message, "WARNING: arptype 65534 not supported by libpcap - falling back to cooked socket."Question: Does this warning relate to my connectivity issue and if so, how can I 'fix' the problem?

I'm running Ubuntu 10.04.1 and am trying to get packet capturing working for my Bluetooth dongle using hcidump.From what I've read, libpcap must be compiled to enable Bluetooth sniffing and given that hcidump isn't finding a single packet, I'm guessing the version Ubuntu has installed for me isn't compiled with bluetooth support.So I downloaded a newer version of libpcap and installed the bluez header files. Configured libpcap and it gave a "Yes" for bluetooth support. It is now installed and sitting in /usr/local/lib/. Now I'm trying to compile hcidump to use this lib rather than the system default but I can't figure out how...I've read that GCC can be passed the -lpcap flag to set the path but I haven't figured out how to do this.
View 1 Replies View RelatedI'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says
"Wired Network Device not managed"
While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.
