Fedora :: NFS Mounts And Ypbind Starts Failing
Aug 11, 2011
I'm building a lab of fedora 14 machines that are supported by an RHEL/CentOS 5.6 server. Everything was working fine yesterday, but today ypbind can't connect to the server and nfs mounts fail with this message:
mount.nfs: mount(2): Operation not permitted
mount.nfs: trying text-based options 'addr=10.9.1.6'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: portmap query failed: RPC: Remote system error - No route to host
I can ping the server from the client using FQDN and ip address.

I have several NFS entries in my /etc/fstab file. Each entry generates an error during boot (from /var/log/boot.log):mount.nfs: DNS resolution failed for macpro.dpc: Name or service not known mountall: mount /mnt/BaseLines [656] terminated with status 32
This occurs even if I specify an IP address in fstab rather than a host name. I was really surprised by that. The odd thing is that by the time the system is up, not only is DNS working as expected, but the NFS shares are mounted as expected. I'd just ignore it for now, accept that it prevents Apache from starting since some of the server's files live on the NFS shares (this is a development system). It appears that the DNS resolver isn't running when the mounts are attempted and that they are attempted again later, after the resolver is running.
I did an
$ sudo apt-get update
$ sudo apt-get upgrade....

I have multiple ubuntu machines and I connect to one through an NFS share. I have done this for a few years without issue. However, since re-installing ubuntu and upgrading to 10.4 I have a problem with my system hanging when the remote shares are lost.
Basically, I can power down the machine downstairs, and my main machine then has a fit. I can not open any folders in ubuntu, nor can I shut down. If I try and shut down the system hangs, last time it hung for 8 hours before I had to kill the power.
These are the lines in my fstab
I don't know what I've done wrong, or how I can prevent this from hanging. I have googled the heck out of this as well and can't seem to find an answer either.

I am trying to set up an NIS client on a Fedora Core 12 64-bit system. The ypbind daemon is running via the /etc/init.d/ypbind script. However, whenever I run the ypwhich command, the following error message appears on-screen:
[code]...
The client has been configured so the domain is set, and the client will broadcast for the first available nis server. The client is on a subnet where there is one nis slave server, so it should bind to that server. One thought that came to mind was the fact the client in question is 64-bit, while the nis slave is 32-bit. Could that cause this problem?

I have upgraded three machines to Fedora 13.
On all of them any attempt to mount an nfs drive fails with:
Code:
This happens immediately - within a few tenths of a second at most. It happens whether I use mount -a(mounts are listed in the fstab file) or a full mount command. It happens on both 32-bit and 64-bit installs.
Nothing appears in the messages log file on either the server or the client machine.
It was working in Fedora 12.
Iptables and ip6tables are both disabled. nfsd is running.
Hosts.allow and hosts.deny both exist on the client, but are empty. They contain nothing but comment lines.
I can ping the server and run ssh shells to it. I can open Web pages in Firefox.
The server is CentOS 5.4.

I am running Fedora 14 with kernel 2.6.35.74 x86_64 and I am having an issue with a Vfat partition that is shared with Windows 7 on a dual boot setup. this partition contains my mozilla profiles and it occasionally mounts as read only in Fedora. I wont be able to write to it and root doesnt seem to be able to write to it when this happens. I checked this by trying to redirect an output of ifconfig. My fstab entry looks like this.
Code:
UUID=5830-75A8 /home/joe/share_storage vfat rw,umask=0000,uid=500,gid=joe 0 0
and ls -l
Code:
drwxrwxrwx. 8 joe joe 4096 Dec 31 1969
These two (fstab and ls -l) always look the same whether the partition behaves as read only or not.

I am trying to get NFS mounts working properly using autofs, but I'm only getting partially results. I have an auto.master set up for indirect mounts and a list of map files for each entry. Forgot to mention that when I mount the directory using /etc/fstab or setup a direct mount in /etc/auto.master I can see files in the mounted directory...

I need to mount tmpfs partitions to /etc & /var and unpack archieves of this folders there. This task is complete working on Gentoo with monolite kernel & handmade initramfs script. But on fedora this method is like hacking. And not pretty for later upgrades, etc... I think, may be it is need to create script in /etc/init.d/ with high run priority. But this method takes many errors on boot. It is need to mount two tmpfs partitions to /etc/ & /var & unpack archieves. All this processes are to be executet after switching init from initramfs to realinit. But before first system processes try to start. How to complete this task with fedora way?

just about to install Fedora 10 on my MSI WIND laptop and read abit about file system on Linux and come across alot of recommendations on how many logical mounts or partition to create..so far i have created /boot of 100MB.i'm unsure of what sizes i will give to my [root] / and /home and /swap
i am thinking of assigning 1GB to /swap which leaves me with 40GB left for / and /home.i'm going to install alot of softwares and probably try out wine as well.i want a separate /home directory incase i change distro then i'll keep it... where does the programs go to under?

On our network, we authenticate our users via LDAP and use autofs to mount their home directories. This works fine in Fedora 8. However, in Fedora 10, when the user logs in, it also mounts the home folders of the users that previously logged onto the system as well. This is what I see when I login as "user1" on Fedora 10

I have installed Fedora 12 i686 Live to a 200 mb partition on an external drive. Before the install I created a 6.7 GB ext3 partition and a 45 GB ext3 partition. The live cd copied the image to a 200 mb partition.
partition 2bce0f9d-53a6-4ec2-b5ad-1a6915c74260 is 45 GB
partition 4683EB23BED2EB34 is 102.6 GB NTFS

Will creating an entry in fstab sdb6 and sdb8 allow the fedora distrib dvd to install to the external hd? How do I create the entries?
I have a raid0 hd with windows xp pro. When i try to shrink the partition using anaconda, I get a disk error and the comper locks up. I have to shut off the ups to reboot.

I have recently decided to rebuild my fedora install and have had several problems installing the updates to the system. I am receiving the following error:

I am more familiar with using sources.list in debian style distros but I am unsure how to proceed with /etc/yum/repos.d. I am currently attempting to either install them from the CLI or to download the binaries, but I do not think that will fix the problem in my repository lists.

The HD containing my main F14 install is suddenly failing with many unreadable blocks. So I booted a different F14 installation I have on another disk.
Then I run dump, for example, as following:
Code:
dump -0 -a -q -v -A sdb1_home.arc -f sdb1_home.dmp -L F14_sdb1_home /dev/sdb1
as, for what I can recall, I've often done to create full backups.
The problem is that running restore with this command:
Code:
restore -i -A sdb1_home.arc -f sdb1_home.dmp
(as, for whatI can...) and using the add and extract commands, only the directory are created. But files are listed using ls. If I add just a file, only dirname is extracted.

So apparently the GNU c++ compiler did not install when I did:
# yum install gcc
And now it's failing to install the C++ compiler when I do:
# yum install gcc-c++
It's saying it's running out of mirrors to check or something? Does anyone know what else I can do to install it?

I've installed F12, updated to today. I've set it to boot to runlevel 3. That works. If I run startx, X starts - I see the mouse cursor and the blue/green background. But no panels. No desktop icons.
I tried switchdesk kde, then startx. Same thing. Except kde is running because if I right-click on the desktop, I get a kde dialog that allows me to start an app.
Tried switchdesk gnome. Same thing. Rebooted, same thing.

Skype doesn't recognise my plugged in mic and earphones. I can hear sound through the headphones from other programs. DVD burner burnt a cd for me, but seemed to pause at around 15-20% and sat there for half an hour. When I ejected CD it jumped to 100% stating it had finished. The CD was a Live Install CD for Ubuntu, which didn't work. I get I/O errors when trying to install from CD on start up. I'm guessing it didn't burn properly or isn't being read properly. I'm generally unsure of what drivers are installed for all of my hardware. Not sure if there is an auto-detection program in or for Fedora that can help, or if I will have to stop being lazy. Skype, like mentioned before. I'm not sure if this is a software issue or driver issue.
Mozilla failing to open. When clicking on the Firefox icon it wouldn't start. Shows an icon at bottom of monitor on toolbar, but disappears after 5-10 seconds with no browser opening. I had recently installed a VLC player with plugin for Mozilla while logged in as root. Wondering if I messed this one up myself? I stumbled onto updates and it had Mozilla install in there. It works again. I'm sure it won't be reoccurrent. If I were to post system specs and issues I'm having, would someone on this forum be willing to guide me through or point me in the direction of having my laptop fully operational? All drivers basically. It works as is, just not completely

Last week, i updated, my fedora. After that, during every boot up, I am getting a warning message like " Your hard disk may failing". It indicates that it is due to bad sectors. But I don't think so. There was a bug reported for a similar problem in fedora 11. I think it is not fixed yet. Hard disk is not having any problem during data access. Other OS including windows are not giving any warning message.

I'm attempting to download the DVD Install ISO for Scientific Linux (Red Hat with some additions for science) to my PC-Laptop external USB Hard Disk, but the download keeps failing near the end.
My PC-Laptop is running Vista 32bit, and the external HD is a 500GB wallet sized Buffalo HD with 400 GB free. I'm no PC sys admin - but the Scientific Linux file is over 4GB in size and I wonder if this might be a problem if the HD is formatted as a FAT32 rather than an NTFS disk (if that's the correct terminology)?
The Windows Vista download window says that I've run out of space on the HD, even though I haven't.
Note that I can't think I can download this as multiple CD's rather than a single DVD distribution - because I'm trying to install this Scientific Linux in Oracle(former Sun) Virtual Box and I'm having difficulties understanding what it wants and was advised by someone to download Scientific Linux as a single iso to burn to a DVD (in the hope that Virtual box will see it for installation in the DVD drive) - but as said I'm unable to even download the DVD installation file.

I ran smartctl and it says "unrecognized" hard drive. I recognized the hard drive the first time I ran the test. But now, it's unrecognized? How come? I don't know how or why this happens. How can I get rid of this problem and the annoying icon?
I tried to run Windows, then started getting errors? This is strange: I've been running Linux the whole day. I last used the Windows hard drive was 2 days ago. Now its screwing up. Window is screwing up the hard drive? HDD has too many bad sectors. didn't touch it, I didn't do much on it, etc? I do not understand?!

I can't get my Fedora 12 laptops to find bluetooth devices. In fact, I can't seem to get bluetooth working at all. This is happening with identical symptoms on two very different laptops, both of which had working bluetooth out-of-the-box with Fedora 10. Under Fedora 12 bluetooth silently fails and I have no idea how to debug it.
Here are the details:
- I'm running Fedora 12 on 32 and 64 bit machines. Both exhibit the same problem.
- I'm using KDE for both (this is the KDE spin of Fedora 12, the 32 and 64 bit versions)
I've got kdebluetooth installed. When I run
Code:
I see:
So I think the right programs are running.
Using the system menus, I can click on "Kdebluetooth4" but nothing happens. There is no bluetooth icon in the system tray, nor have I been able to discover how to add one (I thought clicking Kdebluetooth4 would do that).
I can manually run kbluetooth-devicemanager from the command line, and attempt to look for devices. The devices are never found (they are found by a nearby Windows machine, so I know the devices work). There are no error messages in the GUI, or in /var/log/messages.
On the console, I do see these messages when I run kbluetooth-devicemanager and attempt to discover devices:
Code:
Based on Google searches, that would imply a problem with dbus (I think) but dbus appears to be installed and running.
