Fedora :: F12 NetworkManager Daemon Preventing Boot?
Jul 19, 2010
I'm having trouble booting after a recent bunch of updates (haven't been able to boot F12 from hard disk for a couple of days). The boot process gets as far as "NetworkManager daemon [OK]", then just stops. I get this for all 3 kernels that I can choose from the grub menu (2.6.32.16-141, 2.6.32.14-127, 2.6.32.12-115)Mounting the hard drive with a liveUSB, a quick inspection of /var/log/messages reveals that things go smoothly until: etc. until I hit the power button.I ought to mention that I wireless card that requires the Realtek RTL8192SE driver, which requires
Code:
sudo su

My Fedora box is giving me an SELinux security error:
Code: Summary:
SELinux is preventing the samba daemon from reading users' home directories.
Detailed Description:
SELinux has denied the samba daemon access to users' home directories. Someone
is attempting to access your home directories via your samba daemon. If you only
setup samba to share non-home directories, this probably signals an intrusion
attempt. For more information on SELinux integration with samba, look at the
samba_selinux man page. (man samba_selinux)
Allowing Access: If you want samba to share home directories you need to turn on the
samba_enable_home_dirs boolean: "setsebool -P samba_enable_home_dirs=1"
Fix Command:
setsebool -P samba_enable_home_dirs=1
Additional Information:
Source Context system_u:system_r:smbd_t:s0
Target Context unconfined_u:object_r:user_home_dir_t:s0
Target Objects /home/micah [ dir ]
Source smbd

I was trying to get a daemon to load on boot, I stupidly added it to rc.local and it just hangs. I would love to put in a live CD and edit out the line but the volume is encrypted and I cannot get it to mount.
Is there a way I can cancel the daemon from loading or get to the grub menu (not readily visible since I am single boot) and then boot into a console?

If I turn off the quiet mode in the boot options, it does throw up some errors (e.g. SQASHFS), and then stops after "starting abrt daemon".
On an AMD Athelon. It worked fine of F9, but started playing up, so I'm looking at upgrading.

I downloaded F10 x86_64 live Developer Spin ISO file from fedora project spins website and burned it onto a DVD...Now when I try to boot from it, I get a menu as usual. Here I select the 'boot' option. Now it shows a 'loading' page with a progress bar and 'Fedora 10' written on the right side [as usual].. After that, on the next page I get the following error..
error: unexpectedly disconnected from boot status daemon I somehow did a reboot, and again the same problem. Microsoft XP and another Fedora are already installed on the same system..

Have had a clean perfectly working copy of 2.6.31.6-166 for months and after two updates to 2.6.31.12-174.2.3 and 2.6.31.12-174.2.19, neither of the newer kernel versions will allow machine to boot properly. Start-up hangs at the preload daemon with a flickering screen. To use machine, must use grub chooser and choose the original base kernel.
Running on Tyan h2000m board, opteron 2356, Nvidia 9800 GTX+ and 12GB of dram with SELinux security enabled.

Since my desktop (Ubuntu 10.4.1 for now) has no need for anyone trying to ssh into it, I want to prevent ssh from starting as a service when I boot up.
If I type: sudo update-rc.d -f ssh-agent remove
in terminal, will that stop the service for all boots (until I run: sudo update-rc.d ssh-agent defaults -- in terminal)?
I've already removed (unchecked) ssh agent key from my startup applications

So earlier today I was running out of space on my regular Windows 7 partition and I played around with extending it. I ended up somehow deleting grub and messing up my entire system. I've spent the last 2 hours looking for the answer to this and everyone has been saying to boot from a live disk and fix it that way.
Well, I've tried everything, the only way I can boot right now is via USB and it will NOT allow me to. I checked on other computers and even re-installed and formatted by external hard drive to try and get it to work and it refuses. I've changed my BIOS to boot from USB so I have no idea as to why this is happening. Also, I've tried using the "ls" command to find my partition via "ls (hdX,Y)/" and all of them come up as unknown filesystems.

just a quick question: I have an external HD with 2 partitions, one ext3 and one FAT32.When I plug in the HD both partitions get automatically mounted, but as I only use I use the FAT32 partition to transfer data from/to Windows machines (which does not happen so often) I would like only the ext3 partition to be mounted automatically.

I'm using the Fedora Eee kernel for Fedora 12 (it's an unofficial kernel for the Eee PC), and want to update my system (I just set it up today). How can I update via command line and prevent an update to the default kernel?

I have a virtualbox installation, and I need fairly high security separation between host and guest traffic. The university network the box hangs off uses statically-allocated ip addresses, allocated to fixed MAC addresses (i.e. it eats any traffic with mismatched ip and MAC addresses).
VBox: 3.0.4
Guest OS: Fedora 11 64bit
Hardware: dual NIC, Intel server
Bridged networking, with separate NICs for host and guest
I'm aiming for high-security separation between host and guest traffic. To do this, I would like to to run all host traffic through one NIC, H, and all guest traffic through the other, G. The host and guest have separate, statically allocated, IP addresses, IPH and IPG. The network forces these to be mapped to specific MAC addresses, MACH (the address of NIC H) and MACG (the address of NIC G). So it's not too hard to write host firewall rules to enforce this policy. The rules just have to state that traffic coming into H must have a destination compatible with IPH, and traffic going out must have IPH as source - and vv for G and IPG. There also don't seem to be any trouble telling the guest to only use NIC G. As a result, turning off NIC G (or equivalently, firewalling it off from host traffic) crashes the network, I have to reboot it to get networking working.
But I can't figure how to tell the host to _only_ use NIC H for anything else except the guest. Even though we don't see any IPH traffic coming into NIC G from outside, I don't seem to be able to stop the host from starting connections on NIC G. Does anyone know any way to do this - to tell the host that it can only use IPH as its IP address unless traffic is coming from a guest process, and that it can only use address MACH and NIC H? I've been reading route and arp manuals all day, but I can't seem to figure anything on this - mainly because arp and route don't know about host/guest processes, and I guess weren't designed with this in mind...

I'm running F13 with KDE 4.4.4 on my desktop PC. A few months ago I had occasion to run Kalarm (invoked via "Kickoff" app launcher). Ever since that time, the Kalarm icon appears in my KDE "system tray" after I login. I power down my PC when I'm finished using it for the day.In an effort to get rid of the Kalarm icon, I changed my KDE "session manager" (System settings -> Advanced -> Session Manager) settings to: "on login: start with an empty session". But the Kalarm icon still appears in my "system tray" after the next reboot/login.I've also tried right-clicking on the Kalarm icon and selecting "quit". The icon still re-appears after the next reboot/login.Why didn't the session manager setting: "on login: start with an empty session" get rid of the Kalarm icon?

I have a 2 monitor configuration, with the second monitor uses exclusively for mythtv. When I'm not actually watching tv or a muvie or watching visualizations with music playing, I actually use the machine for more productive uses. As the result the second monitor is typically not turned on, might have something to do the the fact it's a crt design, consumes a fair bit of power and does a good job keeping the media room overly warm.
The question is, does Fedora 11 or newer have a means to prevent applications from opening on the second monitor? I've checked the obvious places and nothing jumps out .
btw: According to the nvidia x server settings control panel the second monitor is set up as in twinview mode. This mode was chosen to allow the gpu to do most of the video decoding tasks using vdupau or something as I recall.

is it possible to block an application from using the network? If yes, how? I read it's possible with iptables and with selinux... Also, what about creating a user who can't connect and run the application with that user?

When I'm logged into my account, I can't shut down the computer if someone else is also logged in unless I supply the root password. However, if I log out, I can shut down from GDM without being challenged, even though another person is logged in, which could cause problems if that person is in the middle of some work. Is there a way to password-protect the gdm shutdown function if people are logged in?

I'm using OpenSuse 11.1 (but it applies also to 11.0) on a Dell XPS, NetworkManager and scpm to manage profiles. I configured wireless network without problems and all runs perfectly. The annoying problem is that the wireless connection doesn't start at boot. Also by clicking on the NetworkManager applet networks are not displayed
But, as soon as I launch network configuration from Yast without do anything other, magically the wireless network is recognized and the PC connects to it.
It seems that the network configuration from Yast activates NetworkManager to connect or it activates the interface or the hardware.

I installed Centos 5.5 yesterday and discovered that the hal daemon was failing to start on boot.
The messages showed that the hal daemon was hanging because nss_ldap could not connect to the ldap server. It eventually failed and the system came up multiuser without it.
When I started looking into the problem I discovered that hald was being started quite early in the boot process. It's sequence number was 26 (if I remember correctly). This was even before nscd.
If I chkconfiged it off and booted, I could start it successfully once the system was up.
I changed the sequence number to 98 and bring it up relatively close to the end of the boot process.
This works and it starts normally.
Is starting it as early as 26 in the boot process done for a reason? It seems to me that it should definitely not be started before nscd. Does it matter that I moved it to the end of the boot process?

I am running a recently built Debian 'Lenny' system 5.0.4.I used the gui install and asked for desktop/file server/ I created a raid 1 systemsing two similar drives.Finally I set up some samba shares to use from my (wife's) windows PC. I wanted to use PC names rather than IP adresses to access the shares so activated wins.My Debian system, called arcturus, did not appear in windows network places. After much trial and error and googling found that the nmbd service had stopped.'/etc/init.d/samba restart' reported nmbd not present, stopped smbd and then restarted both. My networking then all came to life.There is a Ubuntu forum discussion around this subject and the consensus seems that the samba daemons are starting before the network is properly established. I have installed a work-around by putting the restart line in /etc/rc.local.But I'm concerned that I have some kind of configuration error.The following is a section of my log.nmbd after setting logging to level 3:-
Initialising global parameters

I installed VSFTPD via: sudo gedit /etc/vsftpd.conf
I can start/stop using the following:
sudo /etc/init.d/vsftpd start
sudo /etc/init.d/vsftpd stop
By default, the daemon loads at boot but I don't want/need it to. I executed the following command thinking it would stop it from loading at boot code...
Can anyone tell me how to stop the VSFTPD daemon from loading at boot?

I am having some trouble making the dropbox daemon start at boot. I followed these instructions -> [URL], which are basically a replica of the original instructions from the Dropbox Wiki [URL]. The installation went fine, except that the machine still cannot start the daemon at boot. I tried to modify the init.d script a bit (see the attachment), but it still wont work (I am not sure if my changes made any significant difference, though). The daemon will only start if I invoke it manually after login with the command:
Code:
[user@machine:~]$ service dropbox start
Which executes the daemon just fine. I also tried adding this line of code to crontab:
Code:
@reboot /etc/init.d/dropbox start
This command starts the daemon if I check with the command "service dropbox status", but if I execute the official dropbox CLI command:
Code:
~/bin/dropbox.py status
it says that Dropbox isn't running and I still have to execute it manually.
P.s.: The machine runs Ubuntu Server 10.04, with all the latest system patches and updates.

I went to print something and I get this message: Summary: SELinux is preventing access to files with the default label, default_t.
Detailed Description: SELinux permission checks on files labeled default_t are being denied. These files/directories have the default label on them. This can indicate a labeling problem, especially if the files being referred to are not top level directories. Any files/directories under standard system directories, /usr, /var. /dev, /tmp, ..., should not be labeled with the default label. The default label is for files/directories which do not have a label on a parent directory. So if you create a new directory in / you might legitimately get this label.

What's the best way to register a daemon to start up at boot time in lucid? I have tried registering the following script using "sudo update-rc.d"
Code:
This is supposed to get the daemon for opentftp started, but it does nothing, although I can see the results of the "echo 'Server opentftpd started' " in the boot log in /var/log .Any thoughts or general help on what the best way to accomplish such a task is?
