We're seeing NFS hangs with a Fedora 13 client to a Thecus N7700 NAS unit. /etc/fstab entry for the mount is pure default. Sometimes, the hang ups freeze the Fedora client and it has to be power-cycled to reboot it.
View 4 Replieshi, first i'd like to say that i'm totally new to linux, i was allways using windows.
as i was allways unable to install a good and stable ssh-server on windows, i thought it is time to change to linux. i was able to set up and configure a ssh-server on debian but found out, that fedora 15 looks more userfriendly in first place for me. but now i unfortunately experience problems..
the ssh server was already installed, i changed the service setting to that it starts automatically but after i succesfully connected to the LAN, i cannot access the shh via putty for instance. when i type "service sshd status" it says beside other things: active (running). but when i look at the /var/log/messages, it says those two lines:
sshd.service: main process exited, code=exited, status=255
Unit sshd.service entered failed state.
i searched on google without success, the only thing i found was that someone had the same problem with a bad sshd_config file, but i'm pretty sure that everything is alright with my config-file (i checked it several times).
beside this i cant login on the gui, after the firefox update (??) it always says: a problem has occured and the system can't recover bla bla... so i can only use fedora right now commandline-based.. but with this problem i will deal later on...
I have vsFTPd running on my server. If I connect via 127.0.0.1, then all is well and I can use the "ls" command to get a directory listing. However when trying this remotely, the FTP client hangs and I do not get a directory listing.

The last message before the hang is 'Starting NFS client services: sm-notify idmapd'.
My fstab looks like this:/dev/system/swap swap swap defaults 0 0
/dev/system2/swap swap swap defaults 0 0
/dev/system2/root / ext4 acl,user_xattr 1 1

As you may notice, the client computer of which the mkahawa client package is installed is inside virtual box(guest OS) with the user account name pc004 and with the static LAN ip of 192.168.1.4 then the server(host OS) is 192.168.1.2. The program installation says 0% but detail informs successfully installed. Nothing happens after and very confusing
View 1 Replies View RelatedAfter connecting to any host, the openssh client hangs after I type the password. The strange part is, it only hangs if when I use the wlan card. If I connect my phone to the computer and uses it to connect to my server, it works 100%.
If I use any other computer at the wireless network, it works 100%
If I use putty on the same machine, it works 100%
It is only a problem when I use the build-in wireless card, under openSuSE 11.3, on my Lenovo L512. (note that everything besides ssh works completely).
When accessing an NFS mount for a large (200MB+) file transfer, the transfer starts rapidly, then becomes slower and slower until it hangs. On several occasions, it has frozen the client machine. Both client and server are set to default to nfs version 3. Slowdown and hang also occur when connecting to FreeBSD NFS mounts.
Presumably (I hope), there is some sort of configuration for the client that needs to be set. what should be changed in the configuration? This worked out of the box in OpenSUSE 11.0.
I have a problem during BOOT. During BOOT Fedora seems to stop at the following line:
Code: [20.245743 systemd[1]: unit systemd-tmpfiles-setup service entered failed state for more than a minute... and then it resumes.
Is there a good terminal services client available I can connect to my Windows boxes from Fedora12? I am willing to pay for a commercial license if there is a good one
View 7 Replies View RelatedWhen I was using Ubunutu 10, I updated the ATI drivers from their web site and the installation failed. There is no uninstall for it that actually works. So, very annoyed, I switched to the VESA driver by editing xorg.conf as shown below.
I just upgraded from Ubuntu 10 to 11.04 and when it booted up it told me that I do not have hardware to run the Unity desktop. Even on a restart the login menu shows the selected desktop as "Ubuntu" (no classic or anything though my desktop looks just like it did in Ubuntu 10).
After upgrading to Ubuntu 11 it seems to have switched to a proprietary ATI graphics driver which actually seems to work very well. Except, no Unity desktop.
If I click System, Administration, Additional drivers it shows one driver and says that it is enabled and in use. The driver is "ATI/AMD proprietary FGLRX graphics driver" and in the description it says "3D-accelerated proprietary graphics driver for ATI cards".
Is there a way to explicitly turn on Unity or ask it why it doesnt want to run?

I do not really care which driver I use. I have been told there is a new driver included in Ubuntu 11 that supports my video card. Is that the driver I listed above or is thee another that I can activate somehow. What shall I do? I just want Unity to work.
Try disable this driver? Will it automatically pick up some default? Do I have to delete or do something to xorg.conf as well?
Is there a way to tell Ubuntu "forget whatever video card driver or configuration is in place and go back to the default for a new install"? I have tried "dpkg-reconfigure xserver-xorg" but all it does is ask for a password and then does nothing. Everyone says to run this buts its never done anything for me.

I'm wondering what the least err unit/ units are for a working Linux. For instance. Is a kernel + a window manager enough? Then let's say you install one app on top of that - now you have one app you can use, right? But is that right (kernel + window manager)? Do you even need a window manager for a functioning system? Do you need more than the window manager?I'm asking because I'm fixing to build something from the ground up but it isn't a regular Linux thing and I want to approach if from the direction of adding just what I need not taking away what I don't.

View 4 Replies View RelatedI have installed on my computer Solaris10 (64bit version), PCBSD8 (64bit) on 2 primary partitions and 7 Linux distributions (Redhat,Debian,OpenSuse,Fedora,LinuxMint,Slackware,Ubuntu) on the extended partition. I know this might be a stupid question, but here it goes: I have a problem with my actual power supply unit (the fan doesn't work as it should) and I will change it soon. Is there a problem with any of the Linux distributions if I change my power supply unit? I mean, will the Linux operating systems work properly with a new power supply unit or do I have to reinstall all Linux distributions?

View 1 Replies View RelatedI want to ensure I have done all I can to configure a system's disks for serious database use. The three areas I know of (any others?) to be concerned about are: I/O size: The database engine and disk's native size should either match, or the database's native I/O size should be a multiple of the disk's native I/O size. DMA: Disks that are capable of Direct Memory Access (eg. IDE) should be configured for it.
Write-caching: When a disk says it has written data persistently, it must be so! No keeping it in cache and lying about it.
I have been looking for information on how to ensure these are so for CentOS and Ubuntu, but can't seem to find anything at all. I want to be able to check these things and change them if needed. The actual hardware involved is very modest. The point is to get the most out of what hardware we do have, even though it's "not very serious hardware" from a broader perspective.
My daughter from New Zealand gave me her Acer Aspire 4315 Laptop/Notebook Linux System in December 2009 so that I could use it in bed on days that I was unable to get out to use my main computer as I am a very ill man. I was able to log into the unit as she just said to me to use her name and password to. I have been able to use the unit on the internet at home and my other daughters home through a home wireless system. I clicked on the Upgrade Icon which it did, I think it went from a 7. something to 8.something All the way through the set up it asked me questions and I just clicked yes thinking that was what I had to do. My problem now is, that when I turn the unit on it asks me for a username and password. I put the details my daughter gave me but it tells me invalid user and password. All I do know is that a friend of my daughter installed the Ubuntu Program onto the Laptop/Notebook. Can anyone tell me how or what I have to do now to be able to use the unit again as I am getting very frustrated with the whole thing. I am not used to using Ubuntu and am totally lost with it as I have always been a Microsoft user.

View 2 Replies View RelatedI am trying to install Ubuntu 10.10 x64 on a HP Pavilion p6565uk.
My PC is x64 compatible, although ubuntu will not install.
I don't get to any gui, it says ubuntu will continue install in 5 seconds, at 0, nothing happens. The CPU light is flashing, but nothing happens.
After about 10 minutes, it reboots, but when the HP splash screen shows (Before the boot selection screen) it just hangs. I have to do a hard shutdown to boot back up.
I am using wubi for install.
trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface
auto lo
iface lo inet loopback
[code]....
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?
I am writing a TCP server in C, and the server listens to incoming client connections and accepts them. It then creates a thread to handle the client. The clients are expected to only receive data from my server and not send any data. So if I use a select() call with a recv(), I believe that the recv() will just block forever since there will not be any data coming from the client. If I use a non-blocking recv(), then this will just return a 0 which tells me nothing because the client is not expected to send any data. I am not sure if I have misunderstood some socket concepts, but I need a solution to detect when the client has disconnected so that I can close the socket and stop sending data to the client. As I understand it, simple ACKs etc are not captured by the recv(), and only data sent by the client will cause recv() to return a non-zero value, so I am not sure how to know when the client has disconnected.
