I am still puzzled by IT guru who still install a server version of Linux using the default partition system. I am curious about what the IT guys in this forum think about this, even when the server is part of a cluster.

View 9 Replies View RelatedI want to install Ubuntu LTSP on top of an already existing system. However, I want to use a different DHCP and TFTP server. Do I simply just install 'ltsp-server-standalone' with apt and run 'sudo ltsp-build-client', stop the DHCP and TFTP server and stop them from starting automatically? Would I then just copy over the pxelinux.cfg/default file from /var/lib/tftpboot along with the initrd.img and vmlinuz images to the TFTP server?
Edit: Do I need to actually copy the whole /var/lib/tftpboot/ltsp directory over to the TFTP server?
After an update recently I noticed that my process count jumped up quite a bit. Somehow it doesn't seem related (it was an apt update I believe), but I'll just throw it out there. All of the extra processes seem to be related to XFS and JFS file system kernel processes, but none of my file systems use XFS nor JFS, just EXT3 & EXT4. Is there any safe/easy way to kill off these processes and prevent them from re-spawning? I don't find having irrelevant idle processes to be beneficial nor efficient. It's using Ubuntu 10.04 64-bit. Only active file systems are EXT4 and EXT3.

Every time I try to change file or folder permissions on a separate internal drive in ubuntu 10.10 desktop in sudo file manager, It sets it right back to the way it was before and doesn't save the permissions I want to change it to. The files aren't critical system files that are not even existent on this hard drive.
Its on a completely separate drive, Yet aren't I suppose to be in control of what gets changed to what? Instead of a Operating System doing something just for my safety? A simple AVI files permissions being changed shouldn't hurt anything. How to I stop ubuntu 10.10 from auto setting the permissions of my folders and files? Its really starting to me off right now. I've been looking around on google for Auto reset permissions for ubuntu, Haven't found one word about it. Yet I'm just going to assume someone might know how to resolve this? Or has dealed with this before.
I'm just trying to Forcefully set my folders on my separate drive all to 777 because they are all 775 and 755 and I can only access them with Write privileges if I run the SUDO file manager which I really hate having to do every so often I'm sure you can relate to how annoying it is to have to open up terminal and type something in to open a fully priviledged file manager.
Saw a reference to putting the swap partition on a separate drive--just minutes after I was considering that approach. Can't find anything recent on the topic, so asking: Is there an advantage to having /swap on a separate HD from data on /home? My thought was that both disks could be active at once, perhaps speeding up a busy application.

Will the above procedure accomplish this objective, without crippling openSUSE ? The second swap partition has never shown any activity (on SUSE). I understand (from Using shared swap files) that a single swap partition may be shared. Since these areas are relatively small, It is not inconvenient to maintain separate swap partitions.
I have 3 linux systems configured for running applications in each, named system1, system2 and system3. I have around 100 GB of space in system3 under /usr but not much being used. In System1 very less space is there but mostly hits coming here and need to have proper backup, as the system1 is quite old and not planned partitons properly. So I want to use a disk having more space for backup requirements.

We recently had an issue with "cat /proc/mount" telling us that a CIFS file system was mounted, even though the mount was not working correctly. So we're not sure if we can trust linux to report malfunctioning mounts, so we're planning on adding a specific file on the mounted file system, and verify the mount by reading this file from the client side (linux). If linux fails to read it, we know that the mount have failed. But before we go ahead doing this I thought I'd just hear how others are doing this sort of thing - how do you make sure that mount points are up and working?

Running Red Hat (not sure of the build atm) and I need to be able to put all of the IP blocking in a separate file. It will eventually be uploaded to a large number of hosting accounts, and modified from time to time...so it isn't feasible to modify that many httpd.conf files each time we need to add an IP to be blocked. In httpd.conf I can add the "Deny from" line to the following directive and blocks it just fine:
Code:
<Directory "/var/www/html">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

There is an include to pick up all *conf files in ../conf.d, and everything else in there is working just fine. I created a file called robots.conf; it currently has a set of mod_rewrite rules which work. So I added this to that file:
Code:
<Directory "/var/www/html">
Order allow,deny
Allow from all
Deny from 123.456.789.098
</Directory>
It is not blocking access from the IP with it in there.I've done all of the usual things; restarted Apache, cleared browser cache etc. I can also block it using that same directive in a local .htaccess.

View 4 Replies View RelatedRAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.
By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).
A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.
So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?
Is there any way to take a look which process/application is using SWAP partition/file?

View 2 Replies View RelatedI have an acer laptop (TravelMate 7320) which came with Windows Vista. I have made copies of the recovery disk for vista and installed Ubuntu 10.04 and would like to run Vista from a virtual machine in Ubuntu and for this purpose I installed Virtualbox. The problem is that the recover disk that acer provide require the hard drive to partitioned in a certain way otherwise the installation process error outputting "No partition available".
Acer do provide a bootable CD for download from there website to partition the drive before installing from their recovery disk but I have tried this with virtual box and the process doesn't detect the virtual drive. So my question is does anyone know of a virtualisation software for Ubuntu that they could recommend that allow for the partitioning of virtual disk before the installation of an OS? Or even better does anyone know how to do this with Virtualbox?
I want to set up my PC so that I have Windows 7 installed on one hard drive and Ubuntu Studio installed on a completely separate hard drive. I currently have both hard drives installed in my PC and the larger one (640GB) has Windows 7 installed and is currently taking up that entire drive. My other hard drive (160GB) has a wubi install of Ubuntu 10.10 on it so it shows up on the Windows boot menu. What I want to do is wipe the smaller hard drive and install Ubuntu Studio on it and have it show up in the boot menu just like my wubi install does.
I need to know things like:
1. When I install Ubuntu Studio, do I install the boot loader to the MBR of the hard drive I'm installing it on?
2. How exactly do I add Ubuntu Studio to the Windows boot loader?

View 9 Replies View RelatedI've been trying last days a script to reboot periodically my servers. My idea is to execute the script from one machine, and remotelly, restart the other servers. Now, I've configured ssh to access remote machine without password, using key-pair access, but I am not able to run "shutdown" command without password, so the script doesn't finish cause it waits for password to run shutdown with su priviledges
I've been reading about sudoers file, and applied this configuration on remote machine sudoers file.
Code:
# Cmnd alias specification
Cmnd_Alias SHUTDOWN_CMDS = /sbin/shutdown
...
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
myremoteuser myremotemachine= NOPASSWD: SHUTDOWN_CMDS
I've been testing this configuration on remote machine, logged as myremoteuser, executing /sbin/shutdown -r now, but "shutdown: Need to be root" message is returned, so something seems to be wrong in my configuration but I don't know what.
Background: I need some help regarding install X server/apps on a headless(ie. no monitor, no graphic device) server. The server is in fact a virtual one by Amazon EC2. So there's no monitor nor any graphics hardware. Fedora server (6, i believe) is pre-packaged. The problem is that I want to be running a server app with a GUI. The app won't start without the GUI (and I probably need to tweak a few things through its GUI too).
I plan on setting up very very bare minimal X on the server and then uses NX for remote access. Can somebody shed some light here?
Simply put, my questions are:
1) What would be the minimal list of package i need to install?
2) Where can I find docs about installing and setting up NX? I could only find very fragmented/outdated docs about it.
