I want to add some users to multiple groups. syntax of the file to pass to ldapadd? or would I use lapmodify? Does one add/modify a user record to specify the groups that user is a member of? Or does one add/modify each group record to specify which users are members?
I have installed phpldapadmin 1.2.0.5 Using commands in shell I have added two users and some groups into a base (ldif-file) and I see them in phpldapadmin. But when I try to add users or groups by using graphical interface (phpldapadmin) I can't do this correctly because I can't to select a type of new entry and I see a tip "classes of objects from XML does not support LDAP-server". So I can't to create a new entry by using graphical interface. Here is my slapd.conf
I'm building a new ldap server, my first, oh yea. I'm trying several tilities to see which I like best to work with ldap. One of those is phpldapadmin. I downloaded it and put it in the webroot but when I goto http://localhost/phpldapadmin I don't get an webpage for phpldapadmin I get a directory listing.
I am following the way given in the website : [URL]... but after configuring when i am trying to connect to the site [URL]... Authentication Fails and I am not able to log in with my LDAP user "Manager" I am using openldap version 2.4.21
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 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 want secondary users can able to change the files permissions of primary group?user MAC is having www as a primary and httpd as secondary group. But he want to change the file permissions (chmod) httpd group files. Is it possible or not? I think its not possible. If it`s possible then let me know how?
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 found out from here that it is not enable URL...I ran the command mount | grep "shm" and got.none on /dev/shm type tmpfs (rw,nosuid,nodev)So how do I enable it?It is need for my ATI graphic card.
I have 2 threads and both of them are deleting memory at the end nedded by both.
My problem is that maybe it can happen that a thread start and finish before the other one starts and so it deletes the memory nedded by the other thread. How can I synchronize them so that this can't happend.
As a design my threads look like this:
Code:
The other thread looks the same, but this isn't unoff to stop thread1 to finish before thread2 starts.
It is known that binaries with the SetUID bit enabled are a threat for the system.I saw on this ArchLinux wiki[URL].tead_Of_Setuida way to limit the use of SetUID bit thanks to POSIX capabilities.It looks very interesting.Does anyone of you used it already?Is it a burden for the system afterwards (like binaries not working, needing to be fixed); or is it seamless
I've implemented a program URL... which reads digital IF data from a radio receiver through a named pipe, measures power levels, and sends the result to stdout. The program is interactive; there is a thread that reads from stdin to watch for commands, a thread that constantly either reads data from the named pipe or throws data away, and an array of processing threads. The program uses GTK+extra to plot the signals. The IF data stream bandwidth exists at the limits of today's technology (is very very fast).
Problem Statement:The program works fine with a few bugs. I've learned since I've made it that using global state variables to coordinate threads isn't a good way of doing it. I also only had knowledge of mutexes and polled the state variable instead of using other methods.My reimplementation will use the following:
- One "Stdin Command Monitoring" thread - One "Get data from named pipe" thread - One post-processor thread - N Processing threads
All threads are alive during the life of main()There are N buffers. Data will come in from the named pipe, and the "Get data" thread will write the data to an "available" buffer. When the buffer is full it will be marked as "full". There will be N processing threads, one for each buffer. When a processing threads' buffer is full, it will process the buffer and save the result to a final buffer. At the end of a number of averages, the post-processor thread will perform a final process on the final buffer and send the results to stdout.

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?
All my LC environment variables are currently set to POSIX at boot, though I can't find the startup script that does this. I've grepped through /etc/rcS.d and /etc/rc2.d but no luck. In /etc/default/locale, LANG is set to en_GB.UTF-8, which is my preferred locale. But this doesn't stop all the LC's being set to POSIX. Consequently, my dates follow the American convention, which I find hard to read.
I tried resetting with update-locale LC_TIME=en_GB.UTF-8. This changed all the locales to en_GB but only for the session. When I rebooted, everything went back to POSIX. The only change is that en_GB.utf-8 is now in the /etc/default/locale file as the value of LC_TIME as well as LANG.
I have a pthread waiting forever on a POSIX message queue and then call mq_close and mq_unlink on the POSIX message queue. I've found that the pthread never wakes up from it's call to mq_receive and remains blocked indefinitely. Is there a way to wakeup all pthreads blocked on a POSIX message queue after calling mq_close/mq_unlink? The goal is to include error handling during message queue deletion to avoid leaving any pthreads blocked forever.
I'm in the process of writing a program that is a server- it will accept connections and stuff, and spawn a child process for each. However, i've run into a small problem. I do NOT want to bother with keeping track of the processes unless i need to. So, i set SA_NOCLDWAIT (#ifdef) on a SIG_IGN to the SIGCHLD handler through sigaction interface. The standard says that it the kernel will then keep track of reaping zombie processes for me (a HUGE plus). However, upon receiving a SIGINT signal, i want to stop the server from accepting new connections (done), and then wait for there to be no new connections. I was thinking of just putting a loop like so:
However, I'm not *sure* that this will work, especially with SIGCHLD still ignored. So how can i tell if there are still child processes? I can't find any call like int getnumchld(pid_t proc); (i wish). Plus it would be inefficient to spin on that function anyway. OTOH, i would rather *NOT* have to do the same thing in a loop with a system("ps |...>file"); read(file); etc. either. Is there a way i can portably implement this feature (I was hoping i could run it on linux and the major BSDs, at least).
TO SUM IT UP:
How can i tell if a process has no child processes if i've SIG_IGN'd SA_NOCLDWAIT'd the SIGCHLD? Is there a _reasonably_ portable way to do so? I *don't* want to manually wait for EVERY process. Maybe only those still active at the time of SIGTERM, but that requires keeping track of the number of connections and whether those have terminated...
EDIT: Does anyone know if the above code *would* work, even with SIGCHLD ignored and the kernel cleaning up zombies *for* me? I checked the manpage and it doesn't say much.
EDIT1: Note that all of the processes are in the same process group and session. SO i can find them through this as well. Perhaps even setting the uid/gid and finding all processes run by that group?
EDIT2: i have an idea if the above isn't feasible. If there is no "elegant" way to do it, i could reduce the complexity by sending a SIGUSR1 to the whole process group. Each process would then set a flag telling it to send a SIGUSR1 in reply and send a SIGUSR2 when it is done executing. Then i could keep a count of signals. Maybe that would be *easier*. Or perhaps a count of all child processes and just a termination signal to decrement the counter.
I want to communicate between two threads, each belonging to a different process. Iam using message queues for this. I use mq_open()call. I created the queues with the same queue name starting with a '/'. But when I open the queue, the queue ID is different in both the process. What should I do so that both the process have the same queue ID?
In the main thread, i have put up a timer which generates a signal periodically when it expires, which reults in execution going to signal catcher function.when this function is invoked, under certain condition it goes to thread 1 and under another condition it goes to thread 2. The problem lies here that when it goes to thread2,i have a loop to process but it doesnt come out of the loop and hence from thread2, even though timer has expired.
I am running into a Brick wall with this. And thought that the knowledge and expertise here would be a good place to seek help.I have CentOS 5.4 server running Samba on a WinBloZ network. I have the groups all setup and that aspect works fine. But here lies the issues.In a shared directory with group permissions set if someone on the group with permission to this directory creates a file they are the only person that can edit / modify that file. That file need to be editable by the entire group. But the only way thus far I can achieve this is to manually chmod the files in the directory. I know there is a way to fix this, but I have not found it. Can someone please explain how to make this work for me.
This is a interesting confusing problem.Ok I have group with 3 users.I have a folder in /home with owner as root, and group that has read/write permissions.However if a user opens up a file and saves it via samba, the owner changes to the user, and the group members only have read permissions on the file.
