What is the difference between "soft nofile" and "hard nofile" by configuring 'open file'?
For example as below:
Code:
user1 soft nofile 1000
user1 hard nofile 2000
I'm looking for recommendations on how to increase the nofile limit for a daemon running as other than root. Does anyone else do this? It'd be nice if I could employ /etc/security/limits.conf.
View 2 Replies View RelatedI'm trying to increase hard and soft limit of nofile kernel parameter by putting the following initscript into /sbin
Code:
PATH=/bin:/sbin:/usr/bin:/usr/sbin
export PATH
# Increase the hardlimit for open files
[Code].....
But the limits still don't change as if the script is not run during startup.
whats the difference between hard links and soft links?

View 11 Replies View RelatedI am looking for the opinions of some linux users as to why they prefer using open source software and what they perceive as the main differences between it and proprietary software. In particular, I am curious as to what meaning, if indeed any, users and contributors ascribe to the open source community and how they view it on a less technical level.

2) Open Source? How to explain a difference between open source and freeware? Do we really benefit running open source programs instead of freeware? Most of us will never read a line from a source. We want, we require easily accesible binaries.
So why a common window$ user find worthy to run Linux? What can Linux offer? Linux should be as different from window$ as it is possible.
3) Twm window manager is definitely something strange - in the way the vi editor for notepad users. Twm is for some reasons better than any other wm. I started both kde desktop and xfce desktop under twm. Both desktops can be iconyfied. It is your choice which at this moment you prefer. But you can work with both. Full democracy. No more discussions which is better.
4) When finally developers of KDE, GNOME will make these desktop almost perfect they will be obsolete. In fact they are today obsolete. It is about 20 years working in the same manner. Windows, buttons, mouse's click - I think it's enough. At least I am really bored.
5) NextGen UI. Not GUI but UI. A core of the nextgen UI will be an AI
engine. Also see p. 4, we may think about VUI - virtual environements,
you can run all your preferable GUI simultaneously. Or any other today predefined UI (eg. cli).
6) What about windows (parts of a graphical screen)? Nothing. If AI will be in the core you will need windows only for watching video and playing games.
Finall remarks: It is not a project only an idea. My intuition tells me that there is a time for changes. Time for swimming in deep water.

I have searched around and am trying to understand the difference between a hard link and symbolic link (soft link). I found this link is quite useful. But I am still not very clear. I understand soft link is not a copy of original file, but is a hard link a copy or not?

My version of linux has a bunch of GUI icons on the left hand side of the screen (vertical). Most are links to programs.You click the GUI icon and the program opens. When I mount my internal hard drive it adds a GUI icon for the drive. The problem is when I click on this new GUI icon it automatically loads K3b and gives an error message instead of giving me a list of what is on my drive. I deleted the program K3b and tried un-mounting then re-mounting the drive. I then tried the new GUI icon for the drive and now it automatically opens Dragon Player.

However I am having problems because there is a SEVERE lag on my system. So my question is if I buy like a 16 GB USB 2.0 and use that instead of my 4GB one will it make a performance difference? My laptop is the Dell Latitude D600(1GB RAM, 1.6 Ghz Processor, ATI Mobility Radeon 9000) and I AM NOT in the market for a new laptop or a new hard drive. Edit: What about buying an external hard drive and using that instead of USB's?

View 3 Replies View RelatedLast year I had a gui tool for configuring the radeon open source drivers in my old slackware install but now I forgot the name of it. I'm pretty sure it was gtk based and no matter what I type in google I can't seem to find any reference to it. There is a radeontool but that's not it. Anyone know what the name for it was, or something else that provides easy configuring of the open source radeon drivers? I remember it had lots of options to configure including some I've never heard of. Thought it'd be easy to find now since it seemed so officially supported during the time I used it!
View 1 Replies View RelatedI work for a company that makes portable devices running Linux and I was recently asked to make the underlying file system read-only for "security" purposes. Since the distribution is based on LinuxFromScratch, I know that very little writing happens at run time. So, even if the device runs on a usb flash device, I doubt that putting the root file system RO will be that beneficial. I am actually more concerned about a process actually breaking because it cannot open a file in RW mode than a process going rogue and filling the root file system with log files, etc. I'd really like to ear what kind of advantages disadvantages there really is with read-only file-systems.

View 1 Replies View RelatedI am using xubuntu and there are a few types of files on website that instead of downloading and saving and then opening with emacs, I would rather when the radio button choice comes up say open with emacs. I am using xubuntu with xfce, and there is no line for a command to be entered as some ubuntu editions have. In the choice of changing the opening program from mousepad to something else, it says search and allows to navigate to find a program, but I cant find emacs anywhere not in etc/ or elsewhere. So where is its executable to direct the program chooser to?
