Fedora Networking :: Nfs Permission Error On Diskless Environment
Dec 9, 2010
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
how to to setup a PXE boot environment. The server contains a LUbuntu 10.10-installation the client is Ubuntu 10.10 Server (I didn't mix up those two...) So, everything is going fine; the client gets an ip-adres, and boots over PXE. The login-prompt is shown. Problem: I can't login. It seems my users are deleted (better not copied). Of course the system (client) works fine when I boot the system from it's harddrive. The only thing I can guess, there going something wrong with:
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;
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?
I'm attempting to set up a server for performing diskless boots here. I'm using Gentoo 2008, and have followed the instructions here:
[URL]
I've gotten to the end of the basic DHCP setup, and I can not get the server to issue addresses. I've confirmed dhcpd loads up OK, and is running in top.
Here's the contents of /etc/dhcp/dhcpd:
Code: # Disable dynamic DNS ddns-update-style none; # Assume one default gateway for IP traffic will do
I made a diskless image against Fedora15, during the boot I found it displayed the following error message and went into emergency mode.
The error message:

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 a cgi script that tries to get the IP address of a domain. the Domain is defined in Bind, yet it can not resolve it. I put the domain in the host file and it then gives a Error: unable to create socket - Permission denied
I figure I have to do some code changes to the script but here I would like an explaination as to the error I am getting.
I had Fedora 8 installed in few clients and a server (same server for NFS and NIS), and NIS and NFS configured, and was working fine. Yesterday, I upgraded few client computers to Fedora 15 (server is still same), and configured NFS and NIS client. NFS is working fine, I can see home directories.
For NIS: ypwhich, ypcat passwd gives me correct uutput, ypbind is running. The problem is, I can't login to NIS client. The error is: Permission denied, please try again. My nssswitch.conf is
This is weird, today I updated my system and while trying to visudo from single user mode got
"cannot read /etc/shadow: Permission denied"
which kept me from doing anything until I switched to file permissions of 400 on shadow, then back. Is this being experienced by anyone else or just me? /etc/security/limits.conf doesn't seem like it wants to change in enforcing mode either and I can't find any alerts to provide clues on the situation.
I partitioned my drive to dual boot with XP, and I also added in a fat32 partition so both Windows and Linux can read/write to there to share files. I now have a problem with permissions (I know that fat32/vfat does not support permissions.) I can as my normal user read/write to this partition, but I want to set-up a CodeBlocks project on there and this is where I run into my permissions error.I can create it and the .cbp file is there ect. but I can not save any work, it will complain ('could not write', or sometimes with 'maybe this drive is write protected'.) I have something like
UUID=1234-1A23 /repo vfat defaults,umask=000 0 0 in my /etc/fstab
I am trying to use Wireshark and on startup the program pops up a window saying: Couldn't run /usr/sbin/dumpcap in child process: Permission denied Are you member of 'wireshark' group? Try running 'usermod -a -G wireshark <username>' as root.
I ran the usermod command to add my account in the group and checked it Code: less /etc/group wireshark:x:490:myaccount but the same error message pops up.
I have got centos 5.3 running on my system. I have installed vsftpd and created a separate folder to upload files (upload folder created in/var/ftp/pub). From my client end I can download ftp files but when I try to upload files from my client I get a error message 550: permission denied. The upload folder has full permission ie 777. Checked the ftp config file everything looks ok.
I installed MATLAB R2009a in my laptop (Fedora 14 x86-64), the installation was succesful but when I run MATLAB (in a console), appears a message: error while loading shared libraries: libut.so: cannot enable executable stack as shared object requires: Permission denied
I find a "solution", execute in a terminal: execstack -c libut.so
I used several times with differents libraries that I needed, but I run MATLAB in a terminal, MATLAB starts in a terminal, only a prompt ">>" and nothing.
I am trying to set up a windows file server using fedora 14 with samba. when I go to the a windows machine I can log in the the samba server. When I try to go to the folder I need access to I get and error saying "you might not have permission to use this network resource" I am trying to access my home directory. Directory /home/mike, username mike. As far as I can tell it is not a permission of the directory. I have a user set up in samba that uses the mike user account.
I'm trying to control my media center via my netbook but when I ssh into the machine and do Code ...
So I guess the ssh session is trying to start an x session. Obviously I don't want another session but instead use the existing x session that the machine runs anyway (and on which Rhythmbox runs)
googling I found a similar bug for f12 but no solution or fix or anything...
sorry if this is such a noob question. I've never dealt with xsessions in that way...
I run a small home network with a wireless network using Apple airport wireless router. I have two macs and one Linux box (Fedora 13). Everything worked until about a week ago. Now the two macs can communicate with each other, and one of the macs can communicate with the Linux box, but the other can't, which is a bummer because it is a print server.
Pinging from the mac to the linux box gives the error message:
I have a problem with the activation of routing under fedora. The problem lies exactly in the file ip_forward who I didn't not change the value to 1. When I use the command echo 1> / proc/sys/net/ipv4/ip_forward. They appears not granted permission. Knowing that I use the root account.
I'm implementing static IPv6 address on two Fedora 13 installed hosts. These two computers are connected using a switch between them and I use D-ITG to generate traffic in the network.I need to send packet from host1 to host2 using this command and I got permission denied
Code: #./ITGSend -a 2001:db8:c003:111e::3 -T UDP -x recv_log_file -t 30000 -c 32 Connect error in createTransportChan(): Permission denied
Gives error message permission denied. I've seen this in your forums but I still haven't found the fix. I've tried the latest release Wubi downloader too. This one is ran from a CD. Version 10.04
I just downloaded OpenOffice 3.2.1 from the openoffice.org weebsite. I followed the instructions precisely and everytime ended up in the same error message - 'error: can't create transaction lock on /var/lib/rpm/.rpm.lock (Permission denied)'. I am using Fedora 13.
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.
Code: The following partially installed packages will be configured: grub-pc linux-generic linux-image-2.6.32-23-generic linux-image-2.6.32-24-generic linux-image-generic
I installed samba server in my external HDD. But it is not shown in system ----> Administration. Is there any problem. Then How to give permission to access home folder.
I 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
For some reason when i booted up today i got the message: "You are not running under a composited desktop-environment. The Desktop Art Plugin cannot work without one."
Any Idea what this means or how I can fix it? it has stuffed around with my conky positioning too for some reason. Im running Ubuntu Lucid 10.04 with Gnome DE
when i do a screenfetch is says - 'Finding desktop environment...found as 'GNOME'[URL]..
