Red Hat / Fedora :: Cannot See Graphical Output: WinXP, PuTTY, X11 Forwarding?
Jun 23, 2010
I am accessing a LINUX cluster machine via the internet from my PC. My PC is using Windows XP. To access the cluster I use VPN Client and PuTTY. I can access the cluster from my PC without any problems as long as only the command line and no graphical interface are involved. To allow for graphical interface I installed Xming and I enable X11 forwarding for PuTTY. However, the graphical interface/output of the program I am using (GrADS) does not appear. Instead I get the error message ?Segmentation fault?.Does anyone know what what I need to do in order to see graphical interface/output via PUTTY

I have a VM with RHEL 5 without an X server. My host has Windows 7.
I need to connect to the VM and redirect the X11 output of the commands to my host.
I know that if my host were a GNU/Linux machine it would be as easy as ssh -X .
I'm ussing PuTTy to connect by SSH to the VM, I tried enabling X11 forward option in PuTTy config, but nothing happened.

early tl;dr: The fancy grub breaks on my wubi 10.04 install, can I force it to use the old grub?
When I rebuild grub.cfg (last time was yesterday for kernel update to .37), and shut down / reboot, grub breaks because it can't 'loadfont' and a few other errors which are related to the 'graphical' grub boot menu.
To fix this I have to boot into a live CD (also Ubuntu 10.04) and run the following:
Taken from [URL]
Code:
sudo fdisk -l
sudo mkdir /win
sudo mount /dev/sda1 /win
sudo mkdir /vdisk
sudo mount -o loop /win/ubuntu/disks/root.disk /vdisk
[Code]....
I know how to fix it but is there a way to skip having to do this on upgrades
(If I edit the grub.cfg before shutting down then this doesn't happen, obviously, but sometimes I forget and this is the result. I'd rather stop the problem at it's source than fight against the updater).

I'm trying to setup a network with a bridge on Debian Lenny (too bad most bridging information is for 2.4 kernel, maybe I'll write some if I get this to work). I've seen somewhat similar problems involving bridging for VMs and a couple involving Fedora, but people say that it was either a driver problem or it was fixed magically.I'm using a few Intel Pro 100s, which I'm pretty certain have had driver support in the kernel for years now. Magic doesn't happen.Here's /etc/network/interfacesQuote:
auto loiface lo inet loopbackauto br0
iface br0 inet staticbridge_ports eth0 eth1bridge_maxwait 0address 70.168.186.252netmask 255.255.255.254gateway 70.168.186.1

Before I begin I would like to say that while I am not a Linix newbie, I am not a guru or even a regular user so don't assume I have anything more than general Linux knowledge. I am carrying out research involving virtualization and Single Sign On technologies and I need to display a Xen based virtual machine to the desktop before the user is logged in. This is for a demonstration system and I am trying to find a solution that involves the least amount of system modification possible.I found a PAM module that allows for the invocation of arbitrary shell scripts which would allow me to start and display the virtual machine in question, but when trying to run the virt viewer (or any process with graphical output) I am informed that the display cannot be found. Explicitly setting the DISPLAY env to :0 before running the command has no effect.
This is where my Linux knowledge runs out. I know that there has to be some way to connect to the X session being used by the greeter, I just don't know what that method involves. The shell script is running with root privileges, so it can access whatever "X credentials" are stored locally.
I will be thankful for any assistance this forum might be able to provide, but please do not suggest alternatives to displaying a VM for my SSO needs, and please avoid any solution that involves having to write my own custom greeter. If there is absolutely no way to accomplish what I am trying to do without greeter modifications definitely tell me, but I am a security researcher, not a Linux developer so I am looking for the easiest solution to implement, even if that solution is a gross hack.

I am trying to get two way serial communications going between a Windows XP system and a Linux system (RHEL 5).I have /sbin/agetty -L 9600 ttyS0
in /etc/inittab. I am using a generic USB to serial adaptor on Windows (Unitek) and a null modem cable. I have putty configured for 9600 baud, 8 bits, no parity, one stop bit, no flow control.I get the login prompt from agetty in the putty window but input does not work; I see weird characters in the putty screen. I can echo output into the device from windows and see it, but
cat < /dev/ttyS0. just prints out weird characters from what I type.

I am trying to setup a putty session to putty from one Ubuntu machine to another. I know how to setup to connect to the machine from Windows and I am using the same settings for the one I am trying on the Ubuntu machine but it fails to connect. It fails immediately so I believe that putty is not able to find ssh. Is there some configuring that I need to do.

I just installed Ubuntu Remix 10.04 on my wifes MSI U100 netbook. I did a dual boot just in case she had to get into Windows for something. I let the install automatically partion (did the side by side option). Anyway, Ubuntu works fine and imported all her documents and stuff. Problem is Windows XP won't boot. The first time I tried to boot Windows XP I got a message saying the hardware had changed and I had to select safe mode, normal boot, last known good, etc... I booted normally. I got the splash screen followed by a quick flash of BSOD and a reboot. I does this no matter how I try to boot Windows (safe, command prompt, etc). Anyone have any idea what the problem is?

Running Fedora 5
We changed ip's the other day and now ssh is not working. SSH/Putty was working fine before the ip change. Everything else is working fine on the machine. The sshd_config file has not been touched at all since I've been working on the machine.
var/log/messages shows this: Code: bind to port 22 on 0.0.0.0 failed address already in use netstat -an shows that tcp is listening on 0.0.0.0:22 with no port conflicts.

i can't connect to my server using putty.
I have a virtual dedicated server, running - Linux Red Hat Fidora core 6- Pentium 4, 3ghz
I'm attempting to use Putty to log in SSH, but I'm getting an error.
Saying the sever unexpectedly close network connection.
I don't know if this has anything to do with it. This is a new computer, that hasn't logged in using putty before. Also I'm on a home wireless network. It dosen't seem to be a firewall issue, the error message pops up, when the firewall is disabled.
And I just had Go Daddy do a reboot. Oh, and I think I might have entered my password incorrectly a few times, last night.
I remember the Go Daddy rep, saying that my IP address may be flagged, but that it would unfilter and unlock it self within an hour or so. It's been over 24 hrs.
Before the password issue, i was able to log in.. But i can't now.
Others can log in. So there unable to duplicate the problem.
I'm new to Linux, and SSH.
Any help
I'm trying to install some software...

when I try to connect via PuTTY from a windows machine I get " PuTTY Fatal error connection timed out. I try to do so via a router redirecting IPadr:86 to local adr:22 on the Linux machine.
I seems not to be a routing issue since the router is setup to redirect apparently correctly.
Well I have stopped iptables and selinux is disabled. The sshd deamon is running. I can logon with ssh locally "ssh webcamATlocal adr".

I have a dual boot system - WinXP and Fedora 10. I am happy with my fedora 10, but as usual the WinXP has lots of malware on it. So I wish to reinstall it and patch it up with a AV. Is it possible to reinstall WinXP without breaking the system - becoz AFAIK, installing will remove grub from the superblock and then there will be no way to reload fedora even if it is still there. Can't I copy grub and the partition table away and reinstall it from windows after the intallation completes? That way I shall have my dual boot system back as usual if I didnot do any changes to the partition table during the fresh windows installation.

I'm setting up a network for a school. The network has 11 client computers (windows xp) and a server (fedora 10) All I need to do is have a share for all the children to use. (this I did by adding each client to the workgroup specified on samba then I just map the drive). The issue turns out to be that I have over 300 users. The users don't always use the same computer therefore I need the users to be registered on all 11 clients. How can I do this? I have been searching and I've not gotten anywhere. How can I add the computers to a domain instead of a workgroup? What can I use?

I have a home network with 2 WINXP machines and one I am trying to load FC10 on. If I get FC10 to work, I will convert the others to FC10. I am trying to access the WINXP machines through my LAN. I have installed samba. I have gone through a lot of places to try to configure samba. Several places say I have to set the security level on the ethernet card using system-config-securitylevel. When I enter this in terminal, I get command not found. I checked with yum and it is installed. I have tried using the menus but cannot find it anywhere. I can see the FC workgroup from one of the WINXP machines but I cannot look into it. It says I don't have the right permissions. I would like to set it so I don't need a userid/password at all. Can I do this?

I'm not a Linux noob, but I am far from guru. I'm running a single board computer with a slightly customized Debian Etch (customized by the SBC vendor). No Gnome/KDE/X installed. My application is a control application which uses SDL (Simple DirectMedia Layer) to paint some basic graphics on the VGA. I need to run it as root because the application calls iopl() to access an IO port.If I run my application manually from the command line, life is sweet. From Googling around, I found http://www.debian-administration.org/articles/28, and hence I:1) Created a script in /etc/init.d2) Executed "update-rc.d scriptName defaults" to link the script into the boot sequenceAll very straightforward. My application starts at boot. But when I try to SSH/SFTP into the SBC, I get "Connection refused". So I can't manage the SBC anymore, and this is a big problem. I am not sure if it's relevant, but my application starts before the SSH daemon.My script looked like:
case "$1" in
start)
echo "Starting my application"

My home linux box is behind a Linksys WRT110 router. I have enabled the Remote Desktop from System-->Preferences-->Remote Desktop. I then run TightVNC from my WinXP box. As I wish to run a secure connection, my first obstacle comes from PuTTY.
In PuTTY, my settings are as follows:
Host Name(or IP address) Port
xxx.xxx.xxx.xxx 22
SSH-->Tunnels:
[code]....
I recieve "Network error: Connection refused" I have gleened all of this information from other boards and tutorials. I know there is something critical that I am missing.

I finally got magicjack working under a winxp running on a vbox. But somehow I have to login as root and run the vbox as root. otherwise if I run the vbox as a normal user, I cannot mount the magicjack usb device, it appears as a grey disabled box. I am sure this is some kind of permission issue, but not sure how to grant the permission.

I am using Fedora 14 x86_64 as the host and Windows XP under VirtualBox 4.0.4. I have added two ports (TCP and UDP) to the firewall settings in 'other ports' in the Fedora firewall setings. Do i need to do this?I noticed the port forwarding option in the Fedora's firewall settings which asks for either the ports to be forwarded to either local or an ip address. Do i need to do anything here?
In the settings under VirtualBox under Network adapter 1 (which is enabled) and attached to NAT, there is a port forwarding option in the advanced settings. Can the host and the guest port be the same number? If i use 'open port checker' to check if the tcp port is open in windows xp, will it work as it does in firefox under Fedora?
