My necat (nc) doesn't listen! It means when I write "nc -l 3333", I can't communicate data with "nc 127.0.0.1 3333" in another terminal! Also after writing "nc -l 333", I don't see port 333 between the ports which are listening, by "netstat -ln | grep 3333".

I want to send raw data to a usart port of my board connected to linux box. i know the command

would write the raw bits for characters abcxyz to the usb device but the problem is how do i know which device file to write to?there are so many in my /dev.
I have two computers...Ubuntu server and Windows XP client. Both are connected to the internet using Ethernet. I have them connected directly using 1394 to increase speed of large transfers. The internet network and 1394 have different IP address scemes. Internet 192.168... 1394 10.0.0...
I am having problems getting the two computers to communicate with each other. I can ping the server's ip address and and it loops back. Same with the XP's IP address. I can't ping each other.
ifconfig shows my eth0 and eth1 connections are up. The eth1 Link Encap says UNSPEC.(Don't know if that means anything.)

I am running Ubuntu Release 10.04 (lucid), Kernel Linux 2.6.32-26-generic-pae, GNOME 2.30.2.
I have installed the ASUS USB-N13 according to your advice in previous posts, specifically, in your advice to 828688 Ben.
The dongle seems to be operating as it should. The LED does its flashing at what appears to be the correct time. Wicd also looks correct. Networks are found with good signals shown. Everything looks correct. But when I attempt to connect, "validating authentication" runs for quite some time, and eventually results in a dialogue window stating the communication failed. The required WEP password is entered in the RT2870STA.dat file, and again in the wicd window.
I have entered as much detail in the RT2870STA.dat file as I dare, and believe it to be correct.
ndiswrapper is not installed. Network Manager is uninstalled. Only wicd remains.
How can I get two ip addresses to communicate with each other which are not in the same 255 range?
Like:
192.168.0.1
and
192.168.1.1
I'm using Fedora 9 and has finished the DHCP for my eth2 and static on eth0. I would like to add a route so that the 192.168.22.x eth0 and 192.168.26.x eth2 can communicate to each others,.

View 2 Replies View Relatedgiven my computer is in a network consisting of multiple subnetworks, i.e. there are groups of computers: {192.168.1.1, 192.168.1.2, 192.168.1.3 etc.}, {192.168.2.1, 192.168.2.2, 192.168.2.3 etc.},..., {192.168.254.1, 192.168.254.2, 192.168.254.3 etc.}. My computer is 192.168.1.1. So I can communicate with 192.168.1.2, 192.168.1.3 etc. To communicate with other people I have manually switch to the proper subnetwork and take a new ip, e.g. 192.168.2.1. My question is: Is there any way to be member of all groups and communicate simultaneously with ALL computers? And if not, is there a way to find out (without manually changing the ip address) if computers of other subnetworks are online, so one does not have to change the ip and then look for other computers in the new subnetwork?
View 3 Replies View RelatedI downloaded and installed a new copy of Fedora 11 last week onto a new computer (hereafter "proximate"). I also have a remote computer without a monitor running an outdated version of Red Hat Linux (hereafter "remote"). To manage the processes on remote graphically, I ssh from proximate into remote; this connection succeeds without incident in transmitting text (including commands) between the two computers; however, the command "gnome-session" returns: (gnome-session:15789): Gtk-WARNING **: cannot open display:
(The numbers apparently represent the process identifier and vary from instance to instance.) A similar warning (and no accompanying graphics) occurs whenever I attempt to start any graphical user interface from remote via ssh from proximate. The issue almost certainly lies with proximate; remote successfully communicated graphics to the ancient box that proximate replaces.
Interestingly, I cannot communicate via ssh from remote to proximate (within a secure shell from proximate to remote). If I execute /usr/sbin/sshd on proximate as root, then I can login, but even then I cannot execute any commands.
Consider the following output:
If I execute ssh -vvv proximate from remote to proximate, then I get a lengthy output that ultimately ends with "debug1: Exit status 254."
What must I do to communicate both text and graphics among my computers?
I am trying to set up an NIS client on a Fedora Core 12 64-bit system. The ypbind daemon is running via the /etc/init.d/ypbind script. However, whenever I run the ypwhich command, the following error message appears on-screen:
[code]...
The client has been configured so the domain is set, and the client will broadcast for the first available nis server. The client is on a subnet where there is one nis slave server, so it should bind to that server. One thought that came to mind was the fact the client in question is 64-bit, while the nis slave is 32-bit. Could that cause this problem?
One problem has led to another.. I had notebook version 9.10 and it worked OK. I Downloaded 10.04 onto USB and all seemed fine. After upgrade - disaster. I have as Asus Eee PC901.
1. I am in Italy and bought a TIM USB mobile broadband modem - Ubuntu can see the device but nothing happens except a bizzare message with no information at all 'Unable to Open Archive'. I have no idea what that meant nor what I should do to resolve whatever it is, so I went back to my older USB modem which worked under 9.10 - Now even that device does nothing.
2. as a result, Ubuntu software centre does not work, Synaptic Package manager is the same; also update manager.
3. Limited communications are available via the university wireless network. That network requires me to work through their own proxy;port address (with username and password) which I have set up using proxy manager including the username and password. This allows me to carry out web surfing and point to point downloads.
4. Firefox works fine, and it obeys the requirements for registering with the proxy. Thunderbird, evolution, Synaptic, Update manager, Software centre etc all fail because they failed to authenticate with the proxy. They all have been set up to use system proxy. (Also tried direct proxy address;port in each package but no go)
5. The ultimate frustration has come from the direct download of Skype (.deb). Double click and it starts to install then crashes because of numerous dependencies (things like libqtgui4).
I am testing with Suse Linux Enterprise Server 10 in a VMWare environment. I've installed two SLES10 servers, named sles1 and sles2. I can't get the two servers to communicate, even a simple ping won't work. The "Network Adapter" in VMWare is set to "bridged", a setting which has worked fine when installing WinXP in VMWare and connecting to the Internet. I have configured the Network Settings as follows:
SLES1:
-Statically assigned IP Address
-IP-address: 192.168.0.20
-Subnet: 255.255.255.0 (/24)
-Hostname: sles1
Hostname/DNS tab:
-Hostname: sles1
-Domain Name: local
-Name server: blank
Routing tab:
-Default Gateway: 192.168.0.1 (= my router connected to the Internet)
SLES2: same as sles1, with IP 192.168.0.22 and Hostname sles2
With these network settings, the two servers seem totally unable to communciate.
-When I ping sles2 from sles1, I always get the error message: connect: Network is unreachable
-Whatever way I ping, either ping sles2, ping sles2.local, ping 192.168.0.22, whatever, the error message is always the same.
-Even if I ping sles1 from sles1 (= "pinging myself"), I get the same error message.
-Only if I ping localhost, I get a proper ping result.
I have been trying to set up a network bridge for the 2 virtual machines installed on my Fedora 14 host PC. I want the VM's to be able to ping each other and have their own "network" in which they can operate/communicate. What is the simplest way to accomplish this? Most of what I have read revolves around turning off NetworkManager, and the following config files:
[code]...
Once these files are configured and the network is restarted, the bridge should work. Is this true? I have been encountering problems with this process, specifically when I try to link a VM to a bridge.
There is text based game in the Ubuntu repos called gomoku (just 5 in a row) it comes with the package bsdgames. The manual page [URL] lists an option (-b) to run it in the background. I want to try that and if I know how it works create a simple graphical front-end. When I start the program with:
Code:
gomoku -b
it starts and remains active, the terminal does not return to prompt which is OK as the command is not finished. The manual says the program reads from stdin, and this might sound stupid but how to get anything there?
I've tried to pipe an echo command to gomoku which works but ends the program after is receives input.
Code:
echo "black" | gomoku -b
just finishes. After that when you type another command like:
Code:
echo "justsometext" | gomoku -b
gomoku tells it expects either black or white as input. So it forgot the previous "black" because it is a new instance.
How do I pass text to an already running gomoku?

View 5 Replies View RelatedI have a wireless headset that I'm trying to charge through USB. When I connect it, it just doesn't charge. Looking at dmesg, the device isn't recognised, which is not surprising, since I think the USB port is only for charging, and it won't communicate over USB. lsusb also tells me that (apart from other things that are connected to the USB bus, that all of the 'MaxPower' variables are set to 0mA. So what I think is happening is I connect the headset ubuntu queries it, receives no reply, and so doesn't let the port draw any current. As far as I'm aware, there usually is some kind of OS handshaking like this, but it may vary from model of computer to model, so there's no point in saying "my <INSERT USB DEVICE HERE> charges". I am able to charge my MP3 player from the same port (because it's recognised), and I can charge the headset if I use a dumb mains->USB/5V transformer, but it should also work with my laptop. What I think I need is some way of manually setting the 'MaxPower' on the USB ports.

I have also tried variations using "CR0", "CR0", "CR0x0D" and nothing seems to change it. I'm using another application to ensure that I can speak to the Sanyo projector, and I get a correct response.CR0 is a status read of the hardware that should return something like "80" which would mean "STANDBY"However, the responses that I keep getting are things like 3,4, or 5 which seem to be errors, given that they are returned apparently based solely on the length of the String I send, not based on the actual command.
