I have a mythfrontend box that boots diskless - everything works fine. However, when attempting to upgrade the kernel - grub complains about not finding a device, and the upgrade fails.How do I fix this? Other packages upgrade with no problem.

The following partially installed packages will be configured:

I am currently working on a Diskless Fedora10 based PXE image that should auto login and then launch the ICA client without launching the desktop (so normal autostart will not cut it)I have got the image up and running, the clients boot correctly, autologin etc, but still launch KDE, and I was hoping replace the desktop with the ICA Client.

I have followed everything in the fedora 14 documenation about setting up a diskless pxe boot and I can get past initialization. The kernel and initrd load fine from the tftp server. The kernel starts, then hangs after probing USB devices. The messages show that initrd does not have support for nfsroot. I think I need to better understand how to add this in when I run dracut to build the initramfs image.

That is, the thin clients will have to get their OS image via TFTP, and their IP address via DHCP on a *wireless card* - is this possible?What spec should I ask for/search for when buying the WiFi card?

What I did try to work around is,
1. Set portfast to all the ports connected the PXE server and client.
2. Edit pxelinux.cfg/default, try different setting in "ip=" (I did not find any menu in the internet which explain to to configure this file).
I'm trying to set-up a diskless environment on my home network, based on a F12 server and one FC14 client and I have a problem that I think is related to NFS, but googling around I cannot find any solution.
Basicly the client boots correctly, gdm fires up showing the login window, but the system doesn't let me in, if I switch to console (CTRL+ALT+F2) I cannot login with both standard and super user getting a "permission denied" error.
I tryed to mount the exported fs on another computer and ls -l on the mounted dir shows both user and group set to nobody.
If i mount the exported dir on server side (i.e. mount -t nfs localhost:/...) permissions user and group shows correctly

An interesting challenge involving diskless booting a PC
View 1 Replies View RelatedI currently have a debian lenny high performance cluster running seamlessly using dhcp and tftpd-hpa. All nodes are completely diskless, and i would like to keep it that way. I now would like to have a client boot over local into a full KDE desktop.
Here's the cache.
1. I would like the client to also be a node. I would like it to handle processing as the other nodes do, but this one with a full desktop, with ALL data and privileges accessible.
2. The client will have its own workstation graphics. It will need to have that driver loaded without slowing the system.
3. Client will need to be able to use its own usb, bd-rom, dvd, audio, etc. even though it will be booting into the HPC.
4. Wireless. I cannot run 70 ft of lan across an apartment. not happening.
The idea is a media center applicable "powerhouse" with high-end power and graphics for easy media editing, 3d creation, and gaming. Will also be used for webcache over all local, file sharing, and other server applications.

I need to know how to set up this PXE.
In short we are booting Centos 5.4 over PXE to a bunch of diskless clients. Once they are booted - we can login (as local root account) and RDP to windows machines using rdesktop as we require.
The next step of the project is to get user authentication to the Windows Domain controller working for the PXE image.
To do so - we continued with our physical install of Centos 5.4 (used to create the pxe image with rsync as per the wiki page for diskless clients) by following through this page. AD auth works perfect on this box (it has a local HDD install of centos obviously).
Once we rsync'd the changes over to the pxeboot location - and rebooted one of the diskless pxe clients - we get issues.
The issue is that winbind seems to start - however the file "/etc/samba/secrets.tdb" cant be read. We tried removing this file that the PXE clients use and recreating it using
touch /etc/samba/secrets.tdb
My problem is that I can't setup a diskless environment with CentOS 5.4 (server) and CentOS 3.9 (hosts). On the host, I've recompiled the CentOS 3.9 kernel, with these mods:
- added kernel level IP autoconfiguration;
- added NFS file system support;
- added Root file system on NFS;
- added e1000 driver (the host has a gigabit network card);
Then, I have followed the guide at this link: [URL]
But in my dhcpd.conf I'he put other parameters:
ddns-update-style interim;
allow bootp;
allow booting;

Can't install with cd -> using VMw. workstation?
View 1 Replies View RelatedA few years back, Ubuntu announced a "partnership" with Sun Microsystems, and explicitly listed the Ultra 40 Workstation is compatible with the then current version of Ubuntu. I installed that version (8.04) on my Ultra 40 M2 workstations, and everything worked very well. I later upgraded them to 8.10 and then 9.04, with good results.
Well, now I'm trying to jump to 10.04, and I'm having no luck.
A fresh install seems to hang at GRUB (as near as I can tell.) I get a quarter screen of magenta (the top 1/4 of the screen turns magenta) and then ... nothing. Hang. I've tried re-installing with the full graphical install, and got this hang from the Live CD. Using the "alternate install" CD in text mode, everything seemed to install fine, but the first reboot hangs immediately.
Suspecting GRUB 2, I moved to another machine and decided to try an in place upgrade rather than a fresh install. I figured that the upgrade would retain Grub 1, and I'd have a better chance.
So far, "better" is a good word. Only a little better, though, unfortunately. The upgrade from 9.04 to 9.10 seemed to work OK, but upon reboot, I got a message telling me that it was waiting for the partitions to mount. <ESC> gets you to a recovery console, which is great. I can mount all the partitions by hand, and they seem to mount, sort of. "df" doesn't see them, but you can access all files on all partitions, so they really are mounted. When you exit the recovery console, however, you go back to waiting for them to mount.
Have the changes to Ubuntu left the Sun Workstations behind? Do I need to switch to another distro, or put Solaris 10 back on these things? Or are we going to be stuck on Ubuntu 9.04 in our "Advanced Unix Lab?"
I am looking to set my laptop up as a wireless AP which will allow various clients to connect to the wireless nic (wlan0), then funnel traffic to the wired nic (eth0), then on to the router, modem and Internet. I followed this guide and while I've gotten about halfway to my desired results, I've run into a wall.
I have made the changes to /etc/network/interfaces, and have successfully run the nat.sh script (or so I thought). Upon restarting my networking, the wireless AP is available, or at least appears to be. However, the laptop is unable to ping the router or Internet hosts via eth0, and when I connect to the AP, I pull a 169.x.x.x IP address, not the expected 192.168.1.xx address.
My modified /etc/network/interfaces:

I have a truly freakish thing happening here. First I'll start with a general map:
Workstation A (10.10.0.100) - Ubuntu 10.10 joined to mydomain.local via likewise-open
Workstation B (10.10.0.101) - Ubuntu 10.10 joined to mydomain.local via likewise-open
Workstation C (10.10.0.102) - Ubuntu 10.10 NOT joined to any domain
Server A (10.10.0.1) - Windows 2003 AD Server on mydomain.local
Server B (10.20.0.1) - Ubuntu 10.10 joined to otherdomain.remote
As you can see I've successfully installed likewise and I've been able to get SUCCESS notifications from the join. I've been able to log in locally with a domain user and use a domain user password. I've also added a special Group in AD for linuxadmins and then added that to my /etc/sudoers file so I can sudo from a Domain Account. Great right? I'm slowly replacing Windows. But there's a hitch:
I can't SSH from machine to machine! but it's still not quite that simple.
I can SSH from Workstation A to Workstation C as a Domain User.
I can SSH(Putty) from Server A to Workstation A and B as a Domain User.
I can SSH from Server B to Workstation C as an alternate Domain User.
I can't SSH from Workstation A to Workstation B as a Domain User.
I can SSH from Workstation A to Workstation B as a Local User.
I can SSH from Workstation B to Workstation A as a Local User.
I can't SSH from Workstation B to Workstation A as a Domain User.
Complicated enough for you? The simple version is that if it's joined to the domain I can't ssh into another machine that's also joined to the domain while I'm a domain user. But give me a local account and it's as if there's not problem. I tried looking through the logs to find something but wasn't about to find a "sshd" type log. Syslog was completely unhelpful as it doesn't really show anything for the time stamps of my connections. Where does one start troubleshooting this?
I thought it might be a groups thing like the sudoers file, but I don't have an ssh or sshd group. Oh and what does SSH do? What's the error it throws?
Code:
MYDOMAINdomainadmin@workstationa:/$ ssh mydomain\domainadmin@workstationB

I tested 11.04 beta 1 on one of my computers and was happy to see VmWare workstation 7.1.4 to work fine on it. Then I decided to upgrade my most frequently used computer to 11.04 beta 2, but I can't get VMware to work properly. When I click on some of the function button such as start a VM or maybe change a setting VMware just closes. I can't figure it out, I've tried it with Unity, Gnome with effects, Gnome without. Nouveau driver, Distro nVidia driver, downloaded nVidia driver, and VGA driver. It was nothing to do with Video driver, but that is about the only hardware difference with the other machine that works, it has Intel Video.

I've been trying to install VMware workstation 7.1.4- but I've run into a problem. Due some bugs i've had to install vmware a couple of times. Now one time I removed /etc/vmware before uninstalling it. This might be stupid but after I've done this vmware wouldn't uninstall anymore. It would say that there where instances of vmware running though I've never even been at the point that I ran vmware. The installer would say that vmware was already installed so it wouldn't install either. Now I've removed as much vmware files as I could find. But now if I run
Code:
sudo sh vmware-workstation-full-7.1.4-385536.i386.bundle
It wil say
Quote:
Extracting VMware Installer...done.
And then nothing. It will just silently quit. It doesn't give an error, it doesn't start the installer GUI, it will just quit. Now I suspect there are vmware files somewhere that confuse the installer but I've no idea if this is true or where these files are. how to completly wipe any vmware-workstation file from my computer as if vmware was never installed?
EDIT: if I run sh vmware-workstation-full-7.1.4-385536.i386.bundle -r, it will show the installer again but show that vmware is already installed

how I can launch VMWare Workstation? Need to set up a couple Windows clients.
I have several questions regarding installation of Ubuntu 9.10 on top of VMWare Workstation:
1) can the Ubuntu .iso be on a memory stick, or does it need to be burned to a CD, for installation on top of VMWare ??
2) VMWare workstation sits on top of Windows 7, 64 bit. Am I best off with 64 bit Ubuntu or will the 32 bit install suffice ? I am not doing anything performance heavy with Ubuntu, I am just playing with it to become more familar. I've heard such great things.
I have a 64 bit Dell laptop happily running 10.04 32-bit and Windows 7 booting with GRUB. I want to also install Lucid server on a spare 20GB empty partition and I would like to have Lucid server available in the GRUB menu along with Lucid 10.04 and Windows 7.
I don't want to blow away what I already have working and last time I booted from the server CD to try to install it (9.10), it didn't look as easy as when I installed workstation. Will an install of Lucid server gracefully and safely allow itself to be put on a spare partition and install itself in GRUB or so I need to do this manually? If I lose my Lucid workstation install, I am in trouble.
I have been experiencing issues when switching users since my last update; I filed a bug, but I was interested if anybody else was having the same problem:URL...In a nutshell the computer freezes temporarily during the switch user process. The longer it is running, the longer the freeze lasts. When frozen the screen is black except for a mouse pointer; but the mouse and keyboard are not responsive including the usual X command keys (Ctrl-Alt-Del, Ctrl-Alt-Bksp, Ctrl-Alt-F1, etc.).When I get the chance I am going to rollback gdm to see if that makes a difference.
