Programming :: Applying Group Ideology To Web Applications?
Dec 2, 2010
I have built a database driven web application that has a user and group system that works in a similiar way that Linux handles user access. Breif explanation: A users can access various resources, the resources are assigned to a single group and users can have many groups.
Users
Code:
id name
-- -------
1 RedRanger
2 GreenRanger
3 BlueRanger
[code]....
Lets say that RedRanger needs to be denied access to resource a if I remove him from group 33 he can no longer access b or c which is no good. The only alternative is to change a's group and add everyone else to the new group, this isn't so bad for 3 users, but what about 3,000?

I have a text file that currently has around 150 000 usernames in it. I need to somehow group them into smaller groups of 1000 and then add that value into the DB. for example user xzy group 1 (hopefully the groups will be digits incrementing)
[Code]....
how to search for 1000 then assign them group 1 and then 1001-1999 to group 2 etc.

I'm using the serial port of a device to communicate with a hardware. (that can assume some different configurations of baud rate, data bits, etc.) Well, I can obtain that configuration, but I'm not certain in how to apply them to the serial. I'm using the struct termios to do that. I did some search, and found how to configure the baud rate and data bits. I'm doing this:
[Code]....
how I set the stop bits (1, 1.5 or 2 bits), the parity (even, odd, none, mark or space) and the flow control (hardware, software, none or xon/xoff)?

Is there a Linux system call that can be used to get the group name from the GID returned by stat()? I realize that I could parse /etc/groups (if my user had sufficient permissions).

I would like to create a bash script that creates a single group from all users in other groups.
I've been at it most of the day, and I think I'm making it too complicated. I have about 100 lines of code, and it's still now working the way I would like. I'm starting to trip over my own feet with the amount of if statements and variables.

How can I create a user group that restricts Internet privileges to only members in the group, then I will assigns certain applications to join the group for access to the Internet.
For example, I want only group net to have access to the Internet. Group net is then connected to:
Code:
So far, I am using the gnome group policy manager that is standard with ubuntu but Its not working. It is possible that im misdirected and that I should use a firewall instead?

I've been tasked with fixing a Red Hat system that dies with a kernel panic during the boot stage:
Code:
EXT3-fserror (dev sda1): ext3_check_descriptors: Inode bitmap for group 4 not in group (block 67239937)!
EXT3-fs: group descriptors corrupted!
mount: error mounting /dev/root on /sysroot as ext3: Invalid argument
I can boot into a Rescue CD, but I'm a bit out of my element because I don't use EXT3 myself, and I've never had to repair a corrupted file system before.

I have a group (GROUP) with a number of users. I recently added a new user (NEW). NEW is able to read but not write group files, whereas all the other users in the group can read and write to the group files. The permissions for the group files indicate that all members of group should have write permission -rwxrwxr-x
/etc/group indicates that NEW is a member of GROUP
...
GROUP:x:501:GROUP,OLD,OLD2,OLD3,OLD4,....,NEW
[code]....
Don't know if it matters, but both OLD and NEW write to the GROUP files over an internet connection. why NEW can't write to GROUP files? Is there a maximum number of members in a group that I might have exceeded?

I need to create a group that has the same permissions as the users group. Can I have the new group be a member of the "users" group to inherit its permissions?

I have a number of users, categorised into various groups. I would like one of those groups ("developers") to be in the wheel group as well. I don't want to just copy the people from the developers group into wheel, because then when that group changes I'll have to change it in two places. Is there a way to specify that anyone in developers is in wheel, and have that be dynamic?

I've heard a long time ago that linux applications are built by having a CLI first, and later writing a GUI above that. Does someone have any reference/links about that subject? I'm interested in the principles of this method.

If I put
Code:
$r = exec('whoami');
echo $r;
into my php script, it works fine. However, if I put
Code:
$r = exec('myX11application');
echo $r;
it doesn't (to be precise, the script still works, but myX11application is not executed). Of course, scripts are run by user "apache", who doesn't have access to X11 server and doesn't even have DISPLAY variable defined.I installed virtual framebuffer Xvfb, created a small bash script:
Code:
Xvfb :2
export DISPLAY=:2
myX11application
and called it with exec from php, but it still doesn't run since it looks like Xvfb can't start if the normal X server is running (I need that for development purposes). The reported error from Xvfb is
Code:
(EE) config/hal: NewInputDeviceRequest failed (2)
Is there a solution to have php running your X11 applications with normal X server running?

I am using ssh on windows XP to remotely connect to a UNIX server that provides web application development services. The server is called snapper and is also designed to run computer-intensive engineering and GIS applications. I have been able to successful access the server. However, when I try to run an application I get an error message saying:Application initialization failed: no display name and no $DISPLAY environment variable
The ANSYS Launcher could not be started The most likely reason is that your DISPLAY environment variable I either not set (i.e. issue setenv DISPLAY dev:0.0 where dev is your device name) or is set to a device that is not accepting the connection. I was hoping someone could explain to me what the DISPLAY environment variable is and how to set it.

I just installed GNAT GPS and would like it to display under Applications->Programming drop down menu. How does one do this? I have read about creating a .desktop file but tried that and it still does not appear under the menu I like. It does appear on the desktop but not because of the .desktop file.
OS: fedora 14 63-bit
CPU: CPU AMD-64
An example file (if needed) would be nice.
Also, just as a extra, has anyone found the GNAT GPS icon (.png) file?

I've a problem applying a patch in RHEL 3.3.
In RHEL there is a problema with ACL as can be read in: [URL]
I've downloaded the patch from "Attachments". I try to apply the patch, but I receive this error:
usr/src # patch -p0 < aclPatch.txt can't find file to patch at input line 4 Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|diff -uNr acl-2.2.3.org/libacl/acl_get_file.c acl-2.2.3/libacl/acl_get_file.c
|--- acl-2.2.3.org/libacl/acl_get_file.c 2002-09-05 08:19:54.000000000 +0900
|+++ acl-2.2.3/libacl/acl_get_file.c 2004-08-25 12:49:58.000000000 +0900
--------------------------
File to patch:
========================================================
It seem that can't find acl_get_file.c, no?
- Where can I download the src file?
- Or what's the problem?
