Just like the title states. How come this setting is disabled (2 in about:config rather than 0) under Linux by default? Is there a reason to not turn it on?
WatchGuard officially has clients only for Windows and Mac. But I see that it uses openvpn internally. I couldn't connect to WG from Linux.
Is there someone who actually get this working? How?
I have 3 identical internal 7200 RPM SATA hard disk drives on a Linux machine. I'm looking for a storage set-up that will give me all of this:
Different data sets (filesystems or subtrees) can have different RAID levels so I can choose performance, space overhead, and risk trade-offs differently for different data sets while having a few number of physical disks (very important data can be 3xRAID1, important data can be 3xRAID5, unimportant reproducible data can be 3xRAID0).
If each data set has an explicit size or size limit, then the ability to grow and shrink the size limit (offline if need be)
Avoid out-of-kernel modules
R/W or read-only COW snapshots. If it's a block-level snapshots, the filesystem should be synced and quiesced during a snapshot.
Ability to add physical disks and then grow/redistribute RAID1, RAID5, and RAID0 volumes to take advantage of the new spindle and make sure no spindle is hotter than the rest (e.g., in NetApp, growing a RAID-DP raid group by a few disks will not balance the I/O across them without an explicit redistribution)
Not required but nice-to-haves:
Transparent compression, per-file or subtree. Even better if, like NetApps, analyzes the data first for compressibility and only compresses compressible data
Deduplication that doesn't have huge performance penalties or require obscene amounts of memory (NetApp does scheduled deduplication on weekends, which is good)
Resistance to silent data corruption like ZFS (this is not required because I have never seen ZFS report any data corruption on these specific disks)
Storage tiering, either automatic (based on caching rules) or user-defined rules (yes, I have all-identical disks now but this will let me add a read/write SSD cache in the future). If it's user-defined rules, these rules should have the ability to promote to SSD on a file level and not a block level.
Space-efficient packing of small files
I tried ZFS on Linux but the limitations were:
Upgrading is additional work because the package is in an external repository and is tied to specific kernel versions; it is not integrated with the package manager
Write IOPS does not scale with number of devices in a raidz vdev.
Cannot add disks to raidz vdevs
Cannot have select data on RAID0 to reduce overhead and improve performance without additional physical disks or giving ZFS a single partition of the disks
ext4 on LVM2 looks like an option except I can't tell whether I can shrink, extend, and redistribute onto new spindles RAID-type logical volumes (of course, I can experiment with LVM on a bunch of files). As far as I can tell, it doesn't have any of the nice-to-haves so I was wondering if there is something better out there. I did look at LVM dangers and caveats but then again, no system is perfect.
How can i connect to FortiGate1 SSL VPN Remote Access router from Fedora/CentOS or Ubuntu/Debian?
It only working with Windows Internet explorer for the moment using Vbox (But i cant use Windows only for this)
How can i use it from my favourate Linux?

I have a Dell Precision M4500, Intel Core i5 CPU, running Linux (Ubuntu Lucid), and would like to keep an eye on CPU temperature.
I've tried lm-sensors: sensors-detect didn't find any sensors; following its hint ("This is relatively common on laptops, where thermal management is handled by ACPI rather than the OS.") I tried acpi -V but got nothing thermal. The Gnome panel applet "Hardware Sensors Monitor" reports on GPU temperature but nothing else.
What should I be trying next?
I need to be able to set the date on Ubuntu (8.04.4 LTS) to the year 2040 (to test something that isn't relevant to this question). Is that possible?
I can run:
$ sudo date -s "15 JAN 2038 18:00:00"
Fri Jan 15 18:00:00 PST 2038
...but:
$ sudo date -s "15 JAN 2039 18:00:00"
date: invalid date `15 JAN 2039 18:00:00'
Is the limit somewhere in 2038 (or prior to Jan. 15, 2039)? Does this change with different versions of Linux?
I have installed Enterprise Linux Version 5 provided from Oracle
I am able to access Internet using network cable
Please tell me how can I enable WIFI service ,so that I can use internet without the network cable
I just purchase the new wired mac keyboard:
Running on Gentoo Linux it works mostly fine. The only problem i am having is the function keys and swapping the alt and command keys to resemble a regular pc keyboard. When I tried switching to the "mac-us" keymap in /etc/conf.d/keymaps I got garbage when typing (not even qwerty). Is there any specific keymap that I can use to get what I want?
I want to create a linux user account (in ubuntu or debian or whatever release is more suitable for this) which cannot do anything but just view a pre-determined web page. Kind of Kiosk style so that the user can observe what is going on from that web page but; cannot execute or write (and this blocking is preferably made also via GUI i.e. user cant minimize or close the browser, cant view any -start menus- )anything on machine.
How can I do this?
We make use of a java application that manages a pinpad via the serial port.
This works perfectly on windows with the Sun Comm.jar, the supplied dll and the properties file.
Now we are attempting to use this solution on Linux (actually it does run on various other flavours of linux out in the field) - with Ubuntu server mode.
After much attempts - blood, sweat and almost tears we have this scenario:
Java version 1.4.2_17
Linux - Ubuntu
Comm libs - Comm3 supplied by sun with the default driver specified
An external comm test shows the comm ports: /dev/ttyS0 and /dev/ttyS1
But the java application says unable to open port /dev/ttyS1
(using the RXRT files produces invalid port errors)
Has anyone been able to use java 1.4.2 on linux for serial port communication and found a solution that I could apply in my scenario?
greatly appreciated

I have set of DVD disks. I'd like to rip them to .mkv files, but with all information - i.e. all subtitles, and all audio tracks.
Is there any tool on Linux that I could use to do it? I found some Gentoo howto about ripping, but it requires writing shell scripts, and I'd rather use something with clickable interface.
I have a RAID using Promise FastTrack TX2650 consisting of 2 SAS drives. What is a Linux device name for them? Like sda is for first sata drive. I have Windows server so I can't look it directly but need this information for smartctl usage.
Currently, my company internet access for visitor are required to request MAC address from them if they want to access to internet. Can we do something like the Hotel wifi? they just access to the network and just key in the password, then they are able to access the internet for certain time of period. so far, i have looking for linux solution, but they are no such program/application available. do you all have any experience on it?

I've created a presentation as a series of .png images, one per slide. What is a good way to convert these into a .ppt (PowerPoint) that I can give to some audio-visual person? I'm entirely on Linux, with no Windows or Mac software available.
(Or maybe PowerPoint isn't the only game in town for presentation file formats?)
Hello everybody,
I'm not that familiar with Linux but I'm currently working on a aws image for an assignment and I need to display the DB2 version, the OS and the hardware.
Is there a commando or program of some sort I can use for this purpose?
I tried a rpm called "Bonnie" but that only writes the throughput for the system.
Thanks

It seems to me a major part of frustration n00bs have with Linux is due to UUID changes not matching peoples intuition and just working.
Does anyone know a way of making GRUB and /etc/fstab just ASK PEOPLE about UUID changes, instead of just failing after people try moving hard disk? Could this be done in Bash or such?
Is there a different flag or two somewhere we could simply change?
Seems like this, if made to work in common practice could be a major advantage.
let me put it this way..!
i use windows/ my company wants me to use windows
i like Linux
i don't want to use cygwin
i want a simple portable Linux with a development environment aka( make,gcc,g++,llvm,...)
with a bash and vi is enough for me no need any gui.
these 4 points never change. ;)
i tried damn small Linux.. its awesome but it doesn't have what i need.
so is there a portable Linux distribution that i can run from windows using qemu or something with a good up2date development environment?
thanks in advance
I've got an EEE Netbook with Intel Atom processor and Win XP.
Probably 90% of the time I'm using it for webbrowsing and thinking of dual booting it in Linux and then booting into Windows only when I need to...if it would speed things up.
I've tried using FF and Chrome, both are about equally slow on the netbook.
Anyone have any idea of the comparative stats on this?

I want to RDP to Windows 2003 servers, but if I use the default RDP client under Linux, I have only 16 or 256 colors, instead of the 16-bit colors. The display is also very slow.
What are the good RDP clients I can install on my server? This is a server on which I cannot install anything like VNC, or other remote access solutions. I have to stick to RDP.
I have a number of uncompressed audio files recorded off of an analog (POTS) telephone line of fax transmissions. Is there a Linux utility or library I could use to convert these files into images of the fax they contain? I'm not looking to send/receive a fax via a modem, but just to "replay" the communications tones and parse out the fax message.I'm guessing this may not be possible due to duplex issues and not knowing which end of the conversation is sending what,but thought I'd ask to see if anyone knew of something.
Hi i have web server on it also. i had made simple bash script using vi editor..which will open file and then add some lines into it at last it will save automatically...and after that 2-3 linux comand will be run as a specific user.
Now i want to do the same from web browser...so what i need to do for this?
html?perl?python?cgi?....?whcih is easy way to do the same?
Looking for recommendations the best comprehensive browser based administration tool for administering a Linux machine. Ideally this would be distribution agnostic. This could also be an "appliance" type product that would administer multiple machines on network.
This is marked community wiki. Give your answer preferably one product per answer and vote up packages that you recommend also.
Turbo Core is the latest feature found in the new Phenom II X6 processors.
Assuming that the BIOS does not allow you to disable Turbo Core, and you're using Linux (so AMD OverDrive won't run), how can you disable Turbo Core?
