I developed one software which uses GUI(java swings) to install it but now I want to install it on headless linux means I want to install it by command prompt.So it there any way so that I can use same code without much modification or any API's which can convert gui component to command line.

I have a strange problem. I have set up a server to run without a keyboard, mouse, or video. If I boot it connected to a monitor, there is no issue. However, if I boot it without a monitor attached, the CPU just runs at 100%. Below is a shot of my HTOP from the machine: The weird part is that if you sort the processes by CPU%, they don't actually total 100%. I was trying to see what was pushing the CPU so high, but most of the time the running processes only total between 5 and 20%. Has anyone else seen the problem? Any idea what's happening? I'm worried that if I leave it running like that, the processor could burn up. My temporary work around is to boot it up with a monitor, then disconnect the monitor, but that's really inconvenient.

View 2 Replies View RelatedI currently have an FC15 KDE, set up as I like it as a media server, and with squeezeboxserver (for Logitechs media system) running fine. But I'd like to set it up as headless - and it presently needs to have a monitor attached. No keyboard or mouse and it will boot to the login screen (so not a BIOS issue). I need to get it to boot without needing a monitor or requiring a graphical log in. I can administer via SSH and Squeezebox server puts up a webpage. FC15 doesn't use inittab any more, so changing run levels is fraught. I don't want to play with targets without a safety line ...
View 4 Replies View RelatedI've been trying to get my headless Ubuntu 9.10 server to back up files from my Windows XP box and onto a 1 TB Seagate FreeAgent Go USB drive (which is connected to the Ubuntu server). I've tried two different methods, both of which are behaving strangely and not quite working. I'm using SSH to access my Ubuntu server.
The /etc/fstab line for the USB drive looks like this:
Code:
/dev/sdb1 /media/usb-backup-windows ntfs uid=34,gid=34,umask=022,dirsync,sync 0 0
I'm using NTFS because I'd like to share this drive between Windows and Linux. The drive gets mounted fine and I can read/write files after booting up. The way I'd like for this to work is to have my Ubuntu box mount the Windows drive using CIFS. So I mounted the C drive using the following command:
Code:
smbmount //windowsxp/C$ /mnt/windowsxp/C -o directio,iocharset=utf8,noperm,nounix,ro,credentials=/home/user/.smb/passwords.conf
The mount works fine. I can browse directories under /mnt/windows/xp/C, read files, copy files to Ubuntu, etc. So now I have my USB drive mounted and the C drive on my Windows box mounted. Should be good to go, right? Unfortunately, after several minutes (this varies, sometimes it can go an hour or so) of copying files using rsync --archive /mnt/windowsxp/C/ /media/usb-backup-windows/C/ (the actual command I use has more options - not sure if that's important), the server locks up.
The SSH session dies and I can no longer ping it. The server will eventually start responding after several minutes, only to lock up again a few minutes later, and so on and so on. When it locks up, the following messages end up in /var/log/kern.log:
Code:
CIFS VFS: Unexpected lookup error -26
CIFS VFS: No response to cmd 46 mid 59789
CIFS VFS: Send error in read = -11
CIFS VFS: server not responding
I did some Googling on these messages and came across a suggestion to set /proc/fs/cifs/OplockEnabled to 0. I gave that a shot but it didn't make a difference. I also tried plugging in a mouse and noticed that I could make the server respond immediately after a lock up by moving the mouse. I have to move the mouse though - just leaving it plugged in without movement doesn't help. I have to wait for the hang to occur and then move it. Once I do that, things progress for another few minutes.
This got me thinking that I had a lack of entropy and the mouse movement was kicking things into gear. So I tried moving /dev/random to /dev/random-chaos, and created a symlink /dev/random that just pointed to /dev/urandom. This didn't work - same exact behavior. So why in the world does moving the mouse bring the server back and cause it to start responding, if only for a few more minutes until the next hang?
I then gave up on this approach and tried connecting to an rsync daemon running on my Windows box (using Cygwin), instead of using the CIFS mount point. After getting the config file right and figuring out how to run it as a service on Windows, I started getting files copied once again. However, after what seems to be about the same length of time (several minutes to an hour or so), the rsync connection dies and I get the following message in the Windows rsync log file:
Code:
2010/03/22 13:01:01 [4024] rsync: writefd_unbuffered failed to write 4 bytes to socket [sender]: Connection reset by peer (104)
2010/03/22 13:01:01 [4024] rsync error: error in rsync protocol data stream (code 12) at io.c(1539) [sender=3.0.7]
The Windows box is running rsync 3.0.7 and Ubuntu is running 3.0.6, but they are both protocol 30. The rsync error log on Ubuntu doesn't help much - it also says "Connection reset by peer". I've tried this at least a dozen times and it always fails with these messages. It's weird because it's always 4 bytes, never anything different. I also noticed that /var/log/kern.log had the following messages, although they do not line up with the times that rsync died:
Code:
usb 1-5: reset high speed USB device using ehci_hcd and address 2
I did some Googling on this message and tried some stuff that worked for other people. I added dirsync and sync to /etc/fstab. I tried setting /sys/block/sdb/device/max_sectors to 64. Neither one of those made a difference. unloading the ehci_hcd module and dropping back to USB 1.0. However, 9.10 doesn't seem to have that module loaded, so I'm not exactly sure how to turn off USB 2.0 and just try 1.0. I'm not real enthused with that workaround anyway because I have at least 500 GB to copy.
I've kind of run out of ideas here. It's frustrating because the entire reason I bought the hardware and set up Ubuntu was to run backups. I'm not sure if my problem is a networking issue (CIFS VFS server not responding, connection reset by peer), a problem with running headless (wiggling the mouse temporarily prevents the hang), a USB device problem (reset high speed USB device messages), or something else entirely.
I have an Dell 755, and I have installed Ubuntu 10.4 desktop on it, everything works fine. I have it auto login, and run Azureus/Vuse at startup (so it can be a headless Bit Torrent server), it works perfectly. As soon as I try to go headless (no keyboard/mouse/monitor) the machine boots fine (I can SSH / FreeNX to the machine) but none of the GUI/apps load. What I think is happening is that when it boots without a monitor attached it does not load any of the X11 stuff. I need it to. It worked in Ubuntu 9.04 just fine, but now with 10.4 it is a no-go. Does anyone know how to force the X11/GUI to load when there are no monitors/hardware attached? This is the one thing standing in my was of getting Windows out of my house.

I'll also need to install something on my other pcs/macs so that I can get the backups working. I didn't see anything that is similar to the whs connector software (client). Would I need to install a full Ubuntu client to do the backups?

View 9 Replies View RelatedI have a big problem with my home router / server. The symptom is an alomst complete death. The other computers in the house can use the internet, i.e., the PC is not completely dead, but actually routes. However, it suspends all direct traffic: SSH becomes irresponsive, SMB shares disappear, and so on. It cuts traffic even with a VMWare guest it runs. I can ping it, but that's about it.The worrying thing is that it starts slowly. In the beginning it will start by cutting SMB pipes. It will then become very slow, to the point it won't execute a "shutdown" command.Then I sometimes have flood on port X, "sending cookies". That is certainly due to the P2P program, but cold a sustained flood affect communications on the virtual network adapter vmnet8?And then it enters this catatonic state with no special mention on the log.

I have the latest download of Ubuntu Server 10.04 installed. I have not installed a gui for it. I would like to be able to do this from command line if possible.

I'm starting several VMs on a remote headless ubuntu server via ssh using:
Code:
VBoxHeadless -s <vmname>
The VM starts up okay, and I'm left with an occupied command terminal on my local ubuntu machine. So, if I want to start up several VMs on the remote server, I have to open up several command terminals and end up with as many occupied terminals once they're all running. When the local terminal is closed, the remote VM is also shutdown.
Is there a better way to do this without the remote VM being dependent on the local terminal? I'd like to remotely startup the VMs and be able to close the local terminals without shutting down the VMs. I'm sure this must be possible, I just don't know how to do it.
I have a headless system running fine with eth0, but I need to move the system for a while and need to use wireless.

I have two wireless cards installed at the moment, in the hope I can get one of them working and intend to remove one card later.

I find myself in the strange position of having an old P4 system that I want to throw Fedora 10 on - it's a considerable upgrade from the old 866Mhz P3 that I've been using to do some number crunching on. (It's a personal project, but it's CPU intensive, so the P4 is a welcome upgrade.) My problem with it is that the motherboard's AGP socket is dead, and I can't find a PCI graphics card, so I'm trying to do a totally headless install - I have no idea what errors may be shown, if any. All I know is that whatever I've tried up till now hasn't worked.
1. Remove the hard drive from the P4, stick it into a spare, semi working system (AMD Athlon, RAM isn't working too well), install F10 on the hard drive, remove the drive, put it back into the P4, and let it boot. Results: Nothing. No DHCP announcement, so I don't know if it's done anything.
2. Try a variation of a PXE boot using the vnc parameter. I've copied the instructions here with no luck. Tried it using a nearby mirror (mirror.nus.edu.sg) as well as method=cdrom, with no luck on either. Results: Also nothing.Should I give up on this, or is there anything else I should try?
I want to use a headless (no monitor) and armless (no keyboard/mouse) PC as a Linux box that I can remotely access from my other machines. That is I want to make it look like I'm sitting at the console on the Linux box with a monitor/keyboard/mouse.

but, the moment I disconnect the monitor and reboot, the remote desktop connection fails as apparently X fails to start for lack of a "screen". Removing the keyboard/mouse does not seem to be a problem.
Is there a workaround?
