Networking :: Writing To One Disk From Two Or More Computers At The Same Time?
Oct 27, 2010
I've got a few linux boxes (fedora 13 and 11) with a common disk mounted. I'm trying to get them all to write files to that disk, however it seems that only the first to connect actually has permission to write.
I'm very new to this networking stuff and this is a bit of a hack. Is there anyway to give all computers write access to a disk (it's actually a managed back up disk, primarily for windows users but is the only shared disk in the building), or is this likely to be very very complicated?

It frozen up occasionally, when that happens, usually the harddisk light lights up continuously. So I suspect some process is writing to the disk, which prevent other process to go on. how do I find out who's using a lot of IO?

I've just completed a fresh install on natty, and I'm seeing constant disk writes of around 1Mb every couple of seconds.
I looked at iotop to find the culprit, and it seems to be the journalling manager for the ext4 filesystems:
Code:
215 be/3 root 0.00 B/s 19.23 K/s 0.00 % 5.89 % [jbd2/sda1-8]
Is there something I can do to adjust this behaviour somehow? I'm a bit concerned about wearing the disk out before its time...

I'm writing a script that among other things partitions and formats disks using SW RAID and LVM. I've read somewhere that for older versions of Linux it was a good idea to use the dd command to zero the first couple of blocks od a device before partitioning it (or formatting it?) Is this practice still recommended? To what end?

This is a curiosity of mine, and I expect a technical answer, if someone knows it. Why the systems become so irresponsive when doing hard-disk input and output? This happens even if writing is done to a secondary disk where neither the system or the swap are stored.

I've got a Centos 5 machine running with a raid 1 SSD hard drive combo, as I don't know how or even if it's possible yet to wipe the free disk space clean I need to be careful to not fill all the free disk space. As I don't want to fill the free disk space too quickly and was wandering if it is possible to pipe the result of a mysqldump to a FTP client only writing it to the ram and not writing it to this disk.
I've done a bit of research on the subject and have found the two following commands:
Code: mysqldump < mysqldump options> | gzip > outputfile.sql.gz
Code: tar cf - / | ncftpput -c sonic.sega.co.jp /usr/local/backup.tar
I would like to combine the two to make something like this:
Code: mysqldump mysqldump_options > | ncftpput ncftpput_options -c SERVER_IP backup.sql
I haven't actually tried my code as it seems too easy and I'm sure I've got something wrong! If this command is even correct will it prevent the sql file from being written to the hard drive to my local machine?

I've 2 computers (one at the job, one at home), different motherboard types but same chipset, having AM2 AMD CPUs but different clock speed. I don't have (I don't want to buy) internal hard disks for these computers.
I would like to buy one external USB HDD and install the latest Ubuntu. I will carry this HDD to my job and my home. Is it possible to use this HDD as boot HDD on both computer? Even they are not same just similar? Is this a problem for Ubuntu?

Whenever I am busy reading or writing large files, or large sum of files, my computer is unresponsive. Screens are getting greyed-out and I just can sit there and wait until the reading/writing is done.
This is not caused by the CPU which is overstressed because it is not. Look at the attachments and you will see the CPU is used for about 20%. When these pictures were captured the computer was using hellanzb to unrar a long list of rar-files.
When you look at my signature you see the computer is not bad at all, just disk-access is slow. I can transfer files with a maximum speed of 30MB/s. Is that normal or is it very slow? I don't know the numbers. I have 2 SATA disks.
O.S. is Mint 9-Isadora, based on Ubuntu 10.04 and I use the 64-bits version.

For internal security reasons I need to prevent ourmcat logs from writing to the webserver local disk. We set up a separate logging server with rsyslog and need to pipe the log data to it.I am trying to work out how to configure tomcat to send all log data to the logging server via the rsyslog client (running locally) via a named pipe. We are on CentOS 5.6, Tomcat 6 and rsyslog 5.8.1. I need to know: 1) do we use the default logging library or log4j2) where is this configured in the tomcat config3) is there any code that would need to be written to achieve this

I am having a heck of a time trying to find directions on networking my two computers together in order to share files. I have two machines running Ubuntu 10.10 Desktop & Netbook remix.
They are both connected to my wireless router to connect to the internet.

I successfully installed Ubuntu 10.04 on 2 laptops (both are identical in terms of hardware). In addition, I connected both of them (using RJ45 cables) to a switch (just a switch; I don't have a router). Can anybody guide me what should I do / what settings should I specify in each laptop in order to be able to SSH from one laptop to another?

I try to understand the way the network-admin tool retrieve and set information about the network connections, and after reviewing thee code, I still dont undertsnad how it does it. I thought that it should use maybe linux commands such as iwconfig or ifconfig or by using ioctl for get/set the parameters of the wireless, but I did not find such things in the code. It also does not use AT commands for modem devices parameters.
I see that it uses liboobs files, but after veiwing the code, I still don't understand how it works.
These question comes since I work on application which connects to wireless devices (possibly several wifi and modems devices can be connected ), and I try to think how to set/get the network parameters, I thought that a good start will be to look at how network-admin works.

I have a rather strange issue and maybe someone else will clear that up for me.I have an external USB disk (i am using Fedora 13 with KDE) [LG My Netbook Friend (320GB) (HXD5U32GLS)] which doesn't spin down even when not mounted and not in use. While i can turn it off with sdparm i would rather use hal (haven't seen anythin in any file in /usr/share/hal/fdi/policy/10osvendor/ that would relate to spindown time), i have looked at some forums but it is always in some rather weird hackish way like setting some specific device rules in cron.From what i gathered that udev just "points" to hal rules regarding rfkill and all the hardware. Now the question is what command would i have to add to hal's file (i guess i should copy it first to /etc/hal/fdi/policy/ right?) to enable that specific disk to spindown after let's say 30 minutes of being idle?

My DVD drive start working bad recently in KDE 4.4.3 - openSUSE Forums , but this is another very annoying thing happening in my openSUSE box. I have several flash drives, from several sizes and all have the same problem: When I plug them, the drive simply takes a LOT of time mounting and showing the data, but really, a LOT, and meanwhile the flash light blinks the desktop environment its FREEZE, until it shows the mounted drive. Some output from a recently plug that takes again a lot of time:
Code:
[ 4685.082027] usb 1-6: new high speed USB device using ehci_hcd and address 5
[ 4685.579461] usb 1-6: New USB device found, idVendor=0325, idProduct=ac02
[ 4685.579480] usb 1-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3

Every time I boot up I have to go through a disk check and then restart, how do I stop it from happening? When the disk checks happening I press escape and it usually says its deleted inode something because it has zero Dtime or some thing similar and also a paragraph of repeated lines saying something like all system files need alsa base.cnfg it will be ignored in a future release then the disk check completes and it restarts and is fine then, also sometimes it says dev/sda5 (my ubuntu partition) was not cleanly unmounted check forces. Is their a way to stop this happening as it ends up taking ages just to login.

When I start the computer I receive the message that the drive that contains the /home partition has an error. If I press "F" the screen says that the drive is no ready, that I can wait, cancel or manually recovery. If I wait, in about 1 minute, the system starts normally. If I press "M" to repair manually, then I press fsck to repair the disk and apparently repairs the disk. But everytime I start (power on) the computer, Ubuntu always checks the disk and gives a dialog where I can: press F to attempt to fix the errors, I to ignore, S to skip mounting or M for manual recovery

These days I see the disk check that is popping up when my Ubuntu is booting up quite frequently. It says 'press C to cancel' but C (or Shift C or CTRL C or CTRL ALT C) does not have any effect. Pressing CTRL+ALT+DELETE reboots but again ends up in the vicious loop of disk check. How to bypass it? When I need to critically enter the desktop for an urgent pressing info waiting for 20 to 25 minutes disk check is kind of difficult.

We have 5 computers networked with 9.04 installed. On some days, when you click on Place -> Network, then all the computers will show. On other days, like today, it does not show. However, one can ping them and I have been able to print to one computer which has the printer attached. SAMBA is installed on the computers for file and printer sharing.

I have a small home network. Computers A and B are both running Kubuntu Lucid. Computer A has an external USB hard drive attached, partitioned ext3 and mounted to a folder in computer A's home folder. Computer C is running Vista. I installed Samba, and computer C can access all the files on both computers A and B. But using Samba, computers A and B can't see each other OR computer C. That's not really important to me, but they can't
So I installed NFS and got computers A and B talking that way. I like NFS better. It's faster than Samba. BUT, computer B can't access computer A's USB drive, and I need it to do that. When I'm using computer B and I click on the folder the drive is mounted to, the file manager just shows the folder as empty.

I'm using Ubuntu on my laptop but I'm having a small problem. The network is working fine except for the fact that I can't reach anything on my LAN (can't even ping the router), but everything on the outside works just fine. I can even visit my webserver if I type my public IP.
Where should I begin looking for faults?
Here, enjoy some data. I'm using my wlan0 interface, not sure whether eth0 works or not.

I want to be able to access my desktop from work so I first set up a DNS. I can ssh into my own computer and using the ip address but when I try to ssh using my DNS (this is from my home wireless which is Linksys E2000), I get the following error:
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to ****.com [74.79.145.28] port 50000
debug1: Connection established.
debug1: identity file /home/andy/.ssh/id_rsa type -1
[Code].....
I set up the settings on the Linksys to accept DDNS but I am thinking there might be something else I overlooked? I do not understand completely what is happening to debug this. It seems like it initially accepts the connection and then something strange occurs.

Just to gain access to one of my computer across the house I use VNC a lot but the computer changes its IP address every so often that I refuse to just get up and check it. Without giving that computer a static IP address, is there a way to hunt down the computer's IP?
