Tough Network Question

Hi I am not a complete Linux newbie, but I have a challenge that is new to me.

I am wanting to be able to connect to a linux box (Raspberry Pi running Debian) via ssh directly from a single computer. I want to be able to plug in a ethernet cable from a laptop to the Raspberry Pi so that I can configure it via ssh or a webpage.

I have had a few pieces of hardware, routers, printers etc that allow this sort of connection for configuration, I just would like to know how it is done.

My question is how do I set up the /etc/interfaces file to allow the Raspberry Pi to be found by the laptop.

Once configured I would want the Raspberry Pi to obtain its IP address via DHCP when connected to a network.

Any suggestions, ideas would be appreciated.

I am trying to build a socket to retrieve the ethernet packets from ecu. When i run my code on windows there is no problem and the code runs correctly. But when i run my code on Linux it gets stuck at s.recv(65565). I have already set static ip in /etc/network/interfaces as follows: iface eth0 inet static address 160.48.199.91 netmask 255.255.255.0 gateway 160.48.199.254

I tried a simple code of socket on raspberry pi. but it still gets stuck at s.recv(65565). I also tried to implement the program using multicast. but the problem is that when i create a socket for icmp protocols then I could see the data from the ECU after using command "ping -I echo 239.192.255.251" in another terminal. (where 239.192.255.251 is the multicast address) But when I change the socket protocol type to udp, tcp or raw then it again gets stuck at s.recv().

Imp: When i run the "netstat -s" command in terminal then i could see that there are 0 messages received for udp and tcp. But in Wireshark i could see the udp messages from ECU. Is linux killing all the udp and tcp packets ? How should i solve this ?
(complete setup is connected as: ECU ---> Media converter ---> Raspberry Pi. There is no LAN, no firewall, no internet)

Could anyone please help me with this problem ?

I have several computers connected to a D-Link DIR605L router, two with ethernet cables and two through wifi. The Windows XP computer can see itself and nobody else. The Ubuntu (trusty) desktop and Ubuntu (lucid) netbook computers see nobody (unable to retrieve file list from server) and the Windows Vista computer only sees itself. Clearly, I have failed to configure something or a set of somethings.
Do I have to have one of the computers always on, acting as some kind of file server or can the router do this job? This is a new router. My old one (whose power supply went phut) connected everybody without arguing about it and we could share files around, even with a mix of OSs.
Since this is a local network only, I have no firewalls enabled, as far as I know ...
All of the network set-up posts I've found rabbit on about how to get your internet connection working through your router, which is not an option for me. I have dial-up working on the XP computer and a mobile wireless USB dongle for internet access on the trusty desktop.
I've installed samba and a few other packages, but so far, none of them have solved my problem. Can someone please tell me where to start and which tutorials to read? If I have to set up a computer as a file server, I guess it will have to be the XP thing, as it's the only one that is always running, but I'd like to avoid that, if possible, as I speak XP worse than I speak Ubuntu.
BTW, D-Link are no help at all, two hours on the 'phone and they were still trying to get me to connect to an ADSL service I don't have ...

Hello everybody,

I am seeking help regarding sharing internet connection. I would be greatful.

I have;
A Laptop : Samsung RV509, i3, 300GB HDD, 3GB Ram, Dual boot Windows7 & LM 17 cinnamon 32bit. WiFi & Bluetooth available. A Desktop PC : Celeron CPU 2.4GHZ, 40 GB HDD, 1GB RAM, LiveUSB-LM 17 cinnamon 32bit, No WiFi hardware available, No Bluetooth hardware available. A mobile phone : Nokia Asha 500, WiFi & Bluetooth available. An old USB data cable: with which the mobile phone can be connected to the computers. I have successfully connected and transfered data back & forth, and also shared/connected Mobile-Broadband-internet to both Laptop and Desktop.

What I have been doing now is; I have an internet connection to my Laptop with an external modem and Ethernet. Its working fine. I have an unlimited plan and so I want to share this internet connection on the mobile phone too; instead of incuring extra cost by connecting to the internet directly through the phone. I am successful at that. I can share this internet connection on my phone through WiFi.

Now, what I want to do is; without buying any extra hardware, to share this same internet connection on my Desktop PC, too.

What I tried is; I searched the web, but didn't find any solution. Now I am here. Please kindly help me.

Thank you & Regards

hi,
i have a 'Intel Corporation WiFi Link 5100' netcard, formly at start up the system wrote iwlwifi-5000-1, iwlwifi-5000-2, iwlwifi-5000-3, iwlwifi-5000-4, iwlwifi-5000-5 is missing. I downloaded them and put them in /lib/firmware, no the error message disappeared and i'm connected to my router, but i only have internet with ethernet, although signal strenght is 97%. What can be wrong? How can I solve this?
thank you!

When I do apt-get update and apt-get upgrade, both times I have to unplug my ethernet cord right after it's done downloading the stuff and right before it finishes saying "reading changelogs" and stuff because maybe a second or three after it finishes reading the changelogs my firewall will be lowered. If I unplug my ethernet cord in time I just reset the iptables and plug my ethernet cord back in. For really small upgrades it will finish downloading and reading changelogs too quick so I'm not sure if my firewall was lowered or not and I have to reinstall. I just want it to pause or wait for 5 seconds or something after the upgrades are downloaded. Is there any way for me to do this?

Hey all,

I just did a Debian minimal install and am using the package network-manager-gnome to manage wifi. I should also mention I'm running OpenBox. Anyway, network-manager shows up just fine in my systemtray and it lets me connect and displays that I am connected in the system tray. However, when I try to connect to a website it will just say "connecting" for a very long time before timing out. Note that my ethernet works perfectly.

If it helps, this is what shows up in iwconfig after I've "connected" to a network through network-manager:

Code:

wlan0     IEEE 802.11abgn  ESSID:"The Stack Resident Wifi"  
          Mode:Managed  Frequency:5.24 GHz  Access Point: 54:3D:37:02:A5:CC   
          Bit Rate=13 Mb/s   Tx-Power=15 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=33/70  Signal level=-77 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:154   Missed beacon:0

I've searched in many places and I couldn't find someone who had a similar problem. Any help would be awesome. Thanks!

I have visited many forums and know hat this is a very frequently asked questions. I have just installed Lubuntu 14.04 on an old Toshiba NB505. I have tried the
rfkill list all command.
It shows that I have a Hard Block. I have connected with an Ethernet cable and have updated.

The drivers were removed and were attempted to be re-installed in Windows but did not seem to work either.

any added suggestions. I read another post that suggested that I reload Windows as a partition and try adding the drivers again.

p.s. I should add that I am true Newbie and last took a Computer class in 1988...yes
that is correct 1988

Hi I am new to linux kernel programming.

To debugging kernel I am using Debian-Squeeze.

Actually "apt-get install gcc" occur some errors in Debian

When I use ifconfig there is no ethernet so that I guess Internet is

unavailable even if there is internet connection

Below is my screenshot from terminal.

Please somebody help me.

Thanks.

Hi all

I got this interesting problem:

I have a server that has two ethernet connections, cabled up to the switch.

The server has a clonezilla liveboot cd in it which I am currently booting from. The clonezilla is a debian OS.

So from the cmd line I can see I have two eth interfaces that is connected, eth0 and 2.

Now I need to configure one of these two interfaces to do let clonezilla do its job.

The problem is that each of these two interfaces are going to different subnets. I got the two subnets, which we will just call them A and B. And I can't recall whether A belongs on eth0 or B belongs there.

Now I know there is a simple solution to this: config one and try it out. I could do that, in fact I will do that just to save time. But I was wondering, cause when I did ifconfig I can see from the packet counters that these two interfaces are live, if there is some other way to monitor these two interfaces, and by looking at the packets that is being sent to these interfaces, I can determine which interface goes with which subnet?

Or phrased another way: you just installed a new computer, and have plugged in the internet cable, but you forgot to put an IP address on it and really don't want to wait for your IT guy to come in on monday to tell you what your IP is and dhcp is not an option. What do you do?

Thanks
