Does linux kernel 2.6 support suid & guid?. I just read somewhere that "latest linux kernels does not support suid & guid as it can pose a security risk if the setuid attribute is assigned to executable programs that are not carefully designed". I need a confirmation about what I say is correct or if not please correct me.

View 1 Replies View RelatedI'm trying to get my head around compiling programs, and need some things clarified. Can anyone confirm or deny my understanding so far:
1) Program is written in high level language, such as C. File(s) of the program are the 'source code'.
2) Program is then 'compiled' to turn it into low-level code that is both hardware - i.e. Intel/AMD/ARM processor specific, and also Linux distribution specific. This resulting files are called the binaries.
3) I can go from source code to installed and usable program by doing these steps:
./configure
make
make install

View 3 Replies View RelatedUsing CentOS 5.5. I have ssh setup to use a radius server for authentication. When I use filezilla to test sftp I can successfully authenticate and get directory listings, but every time I try to download or upload a file filezilla attempts to re-authenticate which fails because the radius server uses token auth with one time passwords, so the original password used to authenticate is no longer valid. However I can browse directories all I want and it never tries to re-authenticate.
1. is this re-auth just how sftp protocol was designed? like re-auth anytime a user tries a different action, like browse vs download vs upload?
2. or am I just missing something? (very likely, I'm not real experienced with linux)

Which is why I'm glad KDE still values the good old desktop paradigm. I'd like to use unity, but unfortunately, it is impossible to customise in any significant fashion. I will be switching to Kubuntu now. I think a "start bar" is the perfect mouse & keyboard GUI paradigm.
My recomendation to the Ubuntu devs is to give unity an option to replace the awkward (for a mouse) application finder with a "start menu", and also give an option to have the old style of task bar as well.
I am not complaining here. like I said, I like KDE and have no problem switching over. The only reason I care about unity is; I don't want somebody to try Ubuntu, find out you can't customise the GUI at all, then go right back over to windows or OSX.

View 2 Replies View RelatedI am writing a script that is designed to verify an application is running. The if...else statement in question is the following:

I hope this post stands in the right section.I have a commandline i need to enter in terminal when i want to run a program. i tought lets put that piece of command in an .sh file and just click the file to run the program (then i dont need to open terminal first an give in the command) however the .sh file does not open the program. so i propably need to make a executable (application/x-executable).

I see from dumping executables that seg selector 0x10 is assigned to my stack segment and to my data segments (.bss .data COMMON). The code is using 0x08. My question - how can I control this? I've looked at all the command line options and don't see it. I have a different program that uses 0x10 for code and 0x18 for data. I note that the second program has i386 in the architecture field in the linker script, whereas the first one referenced has i686. Is this what causes the difference? I understand that this architecture field triggers something regarding a library named BFD - is this where I should look? If so, where do I find it? I am runnig fedora. Is there a way to control the association of sections in the linker script with segment registers? I can set up segments in the gdt and can asign them to segment registers. I can - when writing in assembler - assign code to a section. I can relate a segment in the gdt with a register.But I dont see how to tell the section which segment register it is associated with Finally I see that the gcc compiler decides - based on how I initialize a variable - whether to put it into bss or data or COMMON. Do I have any control over this?

View 1 Replies View RelatedUsing gnome terminal (Ubuntu 10.10), is there a way to execute the default application associated to a file type, only by typing its name, as it is possible with Windows ?
For example, say I create a mime type associated to every file with the pattern *.abc. Lets say I associate this file type to application 'my_app'.
If I have file 'my_file.abc' in current folder, what I want is that when I enter only 'my_file.abc' at the prompt, it executes 'my_app' feeding it with 'my_file.abc' as first argument. (assuming of course 'my_app' is in the path)

View 5 Replies View RelatedI just bought a new mouse - just a cheapie usb wheel mouse but it has an extra 'thumb' button which I thought I might as well set up to do something useful. I used 'xev' to determine the numbers that the OS had assigned to the buttons, and I found it wasn't quite what I was expecting:
left = 1
wheel-as-button = 2
right = 3
wheel-up = 4
wheel-down = 5
thumb = 8
I thought the right button would be '2' and the 'wheel-as-button' would be 3 - that's just how I've always seen them referred to in explanations, and I thought it was standardised. Not a big deal - the context menus still pop up when I click the right button so it all works ok. (And I just discovered the wheel-as-button does a 'paste' operation when it's clicked. Weird - I've never noticed that before...) But the thing that I find particularly odd: why is the thumb button assigned as '8'. What happened to '6' and '7'? Does the operating system assign these numbers, or are they built into the hardware in the mouse itself? Again, no big deal, I know I can remap the buttons if I need to, but I was just curious as to how this all works and google didn't help.
