Networking :: Connecting Two Debian Machines Together With Crossover On Different Networks?
Jun 24, 2011
Here is the setup I have. Two debain (squeeze machines) A1(eth0,192.168.33.1, netmask 255.255.255.0) and B1(eth0,192.168.43.1, netmask 255.255.255.0). They both have 3 nics'. So I am trying to connect to each other with a crossover cable and I have added the routes manually. eg: on machine A1 route added was
I have dell dimension 4700 I installed slackware 12.2 onto with the of making it a headless home network jukebox that I could ssh into and control via a crossover cable.From other posts I've seen, it looks like I just need to set up the IP addresses under the same netmask, and can use ssh then. On the slackware machine, it does not seem to recognize an eth device.
Code:
# dmesg | grep eth Driver 'st' needs updating - please use bus_type methods Driver 'sd' needs updating - please use bus_type methods Driver 'sr' needs updating - please use bus_type methods
trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface auto lo iface lo inet loopback
[code]....
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?
I'm trying to connect 2 Ubuntu computers with a crossover cable (ethernet). I found the following thread:
[URL]
Its says to go to:
1. In System > Preferences > Network Connections
and under IPv4 tab, change Method to Link-Local Only.
The problem for me is I'm using Xubuntu 9.04 (on 1 of them) and I don't have "Network Connections". Is there a way to get this utility in Xubuntu 9.04 so I can set the method to 'Link local only' ?
I have just upgraded 2 machines to ubuntu 11.04. One was an upgrade, the other a new install. On both machines, I cannot ssh to any machines running Ubuntu 10.04.2 I can ssh to machines running 10.04.1, 10.10, etc. and all those machines can connect to the 10.04.2 machines. I get: Read from socket failed: Connection reset by peer To workaround the problem, I have copied the /usr/bin/ssh on a 10.10 machine to the 11.04 machines.
using a text interface for my computing but I have run into an issue. Does anyone know of a CLI networking tool that will allow me to connect to a non-broadcasting network? I have tried cnetworkmanager and attempted wpa_cli. The first does not seem to support it and I have not played too terribly much with the second. I have discovered that when I boot my comps into KDE and tell NetworkManager to connect to the network cnetworkmanager can find it then, but that does me no good for what I want, which is to boot my computers straight to runlevel 3 and get connected. If it means anything I am running F11 on a Dell Inspiron 1521 Laptop with a Broadcom wireless card (awfully annoying to set up, but it is working fine) as well as F11 on a desktop of my own designing with a Netgear wireless adapter.
P.S. I realize that broadcasting the network would be the trivial solution but alas I am not the admin on the router and he is out of town.
I have 2 network cards in my computer, and I would like to connect them to 2 different networks. Both connections work fine when I use them so that the other one is unplugged, but as soon as I connect the second plug (doesn't matter which one is first) they both stop working.I've been googling and reading dozens of pages about how to set this up, but I still can't figure it out.
One connection gets its addresses from DHCP and that connection is used for pretty much everything. The other connection has a static IP, and is used to access just one other computer, which is in the same subnet as that static IP.I'm using Ubuntu and I've been using the NetworkManager Applet to manage my connections. If I've understood my googling correctly, NetworkManager Applet can't be used alone for this kind of setup, is that correct? (Even though it has that "Routes..." button and "Use this connection only for resources on its network" which I've tried for the connection with the static IP, but they don't seem to help.)
So my questions are:
1. So I really can't use NetworkManager Applet for this?
2. What software / tools should I use instead? (My googling brought up such wildly different solutions, and I don't know which ones are outdated, if any.)
3. Should I get rid of NetworkManager Applet completely?
I'm familiar with routing in theory, totally clueless about the networking tools in Linux, but happy to read manuals and happy to learn to use the command line versions if anyone can point me to the right direction.
I would like to my laptop to connect to two networks at the same time.The first network is wireless through which I access the Internet.The other network is a wired router to which my laptop and another computer are connected. would like to connect to the two networks at the same time so I can access the Internet, and talk to the other computer on the wired lan.My problem right now that I can only connect to one network at a time. Even the act of plugging in the cable for the wired network causes the wireless to cease functioning.Could somebody give specific steps. I am on Ubuntu 11.04.
I'm having another slight issue. On a clean install of Ubuntu Studio (10.10), I have installed network manager (manually, using .deb packages, one at a time, including all the extra ones it required) and I can only connect to non-secured networks. If I try to connect to our home network (which has WEP security), it sits thinking about it for a while (with the wireless light flashing, indicating it is doing something), but after a while, it asks for the WEP password again. it works fine if I turn the security off
I have ubuntu 11.04 installed. I have a D-link USB Wireless Adapter. Ubuntu detected it and it worked fine. I have a Beetel 450TC1 Router which broadcasts my internet connection. Ubuntu recognizes it, and keeps on trying to connect.It asks me for Authentication again and again.( Don't tell me to check the password again, it does work on everything else )And its not the router problem also, as I tried broadcasting through a laptop I have, Ubuntu again detected but couldn't connect and kept asking me for Authentication
I have setup an ubuntu gateway server by using four NIC cards.
eth0 :210.212.235.107 is connected to the internet eth1 :192.168.1.222 is connected to the local network eth2 :192.168.2.222 is connected to another network
Here 192.168.1.222 is the gateway for 192.168.1.0 network and 192.168.2.222 is the gateway for 192.168.2.0 network.These network configurations are working fine, but i want to block inter network communication ie from 192.168.1.0 network to 192.168.2.0 network,i want to block the communication for securing the local networks more.I know iptable rule is enough for this purpose .But i cant find the apt rule for this purpose.
I have a created a wireless connection from the main admin account and checked the box saying "Available to all users", everything is working correctly. I only need to prevent the Desktop Users from switching the connection to another one.
I am trying to configure my android phone (rooted Eris running kaossfroyo 2.2) to be used as a midi controller. Which I am having enough trouble with as it is but it has raised an annoying issue that occurred a month ago when I used the phones tethering network with my laptop. After connecting the laptop to the phones network (either tether, or an Ad-hoc network created using the network manager) I am unable to switch to other networks. In other words when I'm done with the phone-laptop connection I cannot connect my laptop to my home network! When I click on the other network connection I can see that it is attempting to connect in the upper right corner of the desktop (the network icon) but it will not make the connection.
What happens is that the network indicator will make the little circle graphic as if it is trying to connect but it never will display the other circle as green indicating that it has connected. but when I disconnect from the home network that is not connecting I will get a message underneath that will say that ad-hoc network disconnected! If I am switching from the android tether it will say Android-Tether disconnected etc. Even though when I click on network manager it shows that I am attempting to connect to the home network (labeled LIBERTY in my case) upon disconnection it shows the ad-hoc or tether connection being disconnected.
I am absolutely baffled by this! The issue persists even after deleting the ad-hoc connection from the wireless settings tab!!! I would speculate that for some reason the laptop is attempting to connect to the previous ad-hoc connection despite me wanting it to connect to LIBERTY. I am very confused and hope someone can lead me in the right direction.
I have 4 debian boxes networked together through a basic 5 port switch. I am trying to simulate 2 Local Area Networks joined together by a WAN. Right now I can communicate with A <--> B, B<----> C, C<----->D. However, I cannot communicate with Host A to Host D which is the whole point of this experiment. It has to be my static routing is not right. This is a confusing area to me. Right now my routes are
got a watchguard firebox 1000 here, old tech i know, the manuals/pdfs on their site want me to use a crossover cable for the quick setup and I havent got any at the moment, but I got dozens of normal patch cables and switches. Can I use 2 patch cables on a switch to simulate a crossover cable scenario? If so ... would there be anything extra to do to make that method work? --tia
this thread indicates there is no difference other than what they mention in the thread? confirmation on that? [URL]
I just installed qemu and want that my VM should have net access too. So for that I installed bridge-utils and used URl....Add both the interface with the second computer, and the interface that leads to the existing network. Do it with this command: # brctl addif br0 eth0 eth1
So i have a Vista desktop wirelessy connected to the router and a laptop running UNR 10.04. I used a Gigaware Cat5e crossover network cable to connect the desktop and laptop, and the lights light up orange so it's responsive i guess. I installed samba and can access my shared files on vista from my laptop but the transfer is 1mb/sec, i was hoping the crossover could help achieve something like 50mb/sec. Which is why i don't think i set it up right at all. How can I connect vista to ubuntu via crossover cables to transfer files?
At the outset I would like to tell everyone that I am still relatively a newbie in linux. I use a usb mobile broadband data card to connect to the internet, and I recently purchased another desktop for my wife. Both of us do not share any files, but I do not have a router and was wondering if I could share my connection with her using a crossover cable.I did a lot of Googling around and tried various different things, I even followed another thread in the same forum but the most that I have got is my network manager saying that connection has been established. I am however not able to see her computer under my windows network and don't know how to proceed.I don't know where I am going wrong, and considering that my knowledge of networking is at below basement level, I would really appreciate any help in this regard.
I've two networks (network 1 in the apartment, network 2 in the basement/server room) I would like to build a vpn connection between the two networks. In networks 1 I have a 24h running PC/Firewall/Debian Server. For network 2 I would like to buy a RVS4000. Is it possible to connect the two objects (Debian and Cisco)?
Ive just installed ubuntu on a small nettop type pc. It can connect to the internet but I want a direct network connection thru gigabit LAN using a crossover (apparently a straight cable would have been sufficient). Anyway, I have no idea where to begin. The network connection manager in Ubuntu shows Autoeth1 which is right and, if I manually set the IPv4 I can get the PCs to somehow see each other and the 7 pc to give a 'network access only' but that's it.
I've been reading too much and understanding too little. What I have: Lucid laptop & desktop. Both have ethernet > hub > internet. What I want: connect them directly by the serial ports so the laptop can access the desktop's drives, and the desktop can be retired from the internet. I've got an old DB-25 null-modem, last used for multiplayer Doom. The laptop's dock has DB-9, so the connections is desktop > null-modem > Belkin DB-25 - DB-9 cable > laptop.
I had hoped this post would get me somewhere:[URL].. No such luck. When I ping 'grin.local', the connection is through the internet. If I disconnect the hub, i cannot ping.
Dunno if there's something more I should do to enable serial connection in Lucid, or if my null-modem is no longer good. I'm also rather curious how "grin.local" manages a connection through my ISP's system. These are DHCP. Shouldn't that have required the full numerical IP?
(It's nothing to do with the hub. Checked that by connecting a third box to the hub. My ISP only hands out two IP. I couldn't ping the third box.)
I have a desktop running Ubuntu 8.04. I installed 10.04 on my laptop. When I mount my desktop music folder on my laptop and transfer files, they now only go at 100-200 KB/s. When I had 9.10 installed, they transferred at 1-2 MB/s.
This is the command I use to mount the directory: sshfs matt@169.254.6.233:/home/matt/Music/ /home/matt/Music/desktop/ Is there any way I can speed it up to get it back to max speed?
I tried to connect two ubuntu computers via crossover network. But sometimes they can connect and see each other and even ping each other and sometimes not! Each time, each of my PC's can ping it's own IP address but may not ping the other PC. I tried to disconnect cable, reconnect, disable network, enable it again, change IP address, disconnect via Network Manager Applet, reconnect and... . But when one of them don't want to connect I can't do this anyway! Anyone knows what must be the problem? Sometimes it took about many seconds to get them connected, and sometimes they can't connect for many hours. I must add that I have an ADSL modem on one of two Ubuntu PCs that connect via another cable.
I have a home network and I use Samba to share files. Now when I am on the network, I can see the shares just fine, but if I use a crossover cable, I cannot see or access the folders or files.My goal is to use a crossover cable from one computer with clonezilla to my server in order to use Samba to make an image of my workstation and save the image on my server.But everytime I try to connect with clonezilla I get a persmissions error and the share will not mount. I tried going to the shell and mounting as root, but that did not work either.
I have another server which is only a console and it works though I am unsure why. The share though is a mounted usb drive while on the one that does not work, it is on the internal hard drive.I was wondering if anyone had any ideas or anything I could try to narrow down the problem. Oh, I can access the share using ssh, but not samba. One other thing, the shares are set to allow read/write access to everyone so I don't see why I can not access it.
I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.
This is the output: emil@emils:~$ iwconfig lo no wireless extensions.
I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.
i installed unix services for windows 3.5 on a windows xp pro box and it installed fine. I configured nfs on the debian box and exported the ip of the client computer and forwarded port 2049 correctly. I followed the instructions for setting up teh nfs client on windows. However whenever i go to tools->map network drive and type in the server-domain-name:/file-address it says it cannot connect?
I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.
Ive managed to install samba, I've shared a folder. I can access from a Windows 7 machine via \ubuntupublic. I can put files in the folder form the ubuntu machine and edit them on the windows box. I can put files in the folder/share from the Windows box but then I cannot edit them on the Ubuntu machine (they are read only and have a "Lock" over them). I can fix this by going to the properties of the file/folder in Windows and manually assigning "Everybody" full control (then the lock disappears and all is well.) I want read/write access to all the folders contents from both machines all the time (security is NOT a concern I WANT the permissions wide open) what am I doing wrong?
