I installed a while ago two CentOS 5.3 servers. One of them was running Samba and another OpenLDAP. I configured Samba to act as a PDC on the network and everything was working fine. I was already on policies configuration and desktop migrations.
The following problems are Samba server problem, LDAP server is on hold until I figure out the first problem.
Software conf:
Hardware conf:
One day, both servers began crashing, and after a while, it showed the following during the boot on Samba:
After that, ALL CentOS installations had this problem after yum update, epel installation and some smb.conf modifications:
I figured out it might be EPEL (i did installed yum-priorities and tryied updating the base sistem BEFORE epel installations), so I installed the system without EPEL yum repository. After some good and relieving 15 min working, the system crashed AGAIN after yum base update and showed the following on boot time:
And it stops right there.
Maybe some wrong kernel update? the first time it crashed in one way, with running updated system (After the first update, no manual update was done). The sequel problems were all after Kernel update and EPEL. The last one was just after Kernel update. I'll try one last time with NO updates, but i can't run the system like that.
I can't do anything that might one day crash, it's a 6000-7000 user gov environment, but i don't want to install another distro, so if I don't figure it out, they will order me to.
I have a machine running on RH with 4G memory and 8G swap.Just now I'm having a problem when loging in with a user - just call it "userX" -.Each time I'm logged in I got a message Code:-bash: fork: ource temporarily unavailableAnd almost everytime I entered any command, it gives me the same warning. In some time (rarely) it will give me proper result, but almost any time it gives me the warning and no result.When I use 'top' command, it shows that I still have 500M free memory and about 8G free swaps. Plus the process for userX is less than 20 processes, and each of them are short processes (less than an hour, mostly just few seconds).As a note this problem only occur on userX, for any other user on the machine everything works just fine.
I'm working a program to implement a simple multi-process browser. The browser works by having a ROUTER process as the parent of everything else in the program. There's another process called the CONTROLLER which is part of where the user can input information. To tell the ROUTER to make a new tab in the browser the user activates a function from the CONTROLLER to send the create new tab information to the ROUTER:
I have had ubuntu installed for a few months now and have been loving it. Yesterday I wanted to get JDK installed for a found a forum that said how to install it on ubuntu. The installation was not a success (I am not sure why because I am not skilled when it comes to the command line and I didn't understand the error). Later, I tried to install a different application just through the ubuntu software center and it said it was waiting for a different software manager to finish. I didn't understand what was still running because I had all other applications closed that I know of.
Once I restarted the problem was the same. Then I found a bug where people had the same problem with the software manager and they entered this and fixed it: sudo dpkg --configure -a Now whenever I try to apt-get anything I get: E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
Today when tried to install a software from the terminal...d command dint work. Check this.
calvin@calvin-desktop:~$ sudo apt-get install pidgin [sudo] password for calvin: E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? calvin@calvin-desktop:~$
It says that it cannot get lock! I have installed ubuntu along with windows! and drive E: is in windows.
I am running ubuntu 10.04 and am trying to get updates via the update manager but continue to get the following errors: "E: could not get lock /var/cache/apt/archives/lock - open(11:Resource temporarily unavailable) E: Unable to lock the download directory"
I have a few updates that I can install using the Update Manager but when I click the "Install Updates" button I get this pop up window message E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable) E: Unable to lock the download directory How to get the updates?
I was just mucking about in xfce, trying out new window buttons in conjunction with the black theme - dusk?? - when POW! - X shut down. Rebooting didn't restore things. Error is along these lines:
xfce4-session: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0. xfwm4: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0. [Code]....
Is there a config file I can edit to get away from the window button setting it dislikes, or is reinstalling xfce the only option?
When i connect windows server 2003 from ubuntu these error displayed .When i installing the tsclient, by executing these following command from a Terminal window:
sudo apt-get install tsclient
When i run these command the following error displayed.
E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
I recently installed Ubuntu 11.04 on an old Sony Vaio laptop. I was following some of the steps here..[url]
The step "Enable Full DVD Playback(Dual Layer DVD Support)" did not finish correctly doh and now I can't use 'sudo apt-get' for anything or the software center or using the 'Update Manager' does not work.
The update manger says it may be caused by an update not finishing correctly which sounds correct as explained above. The apt-get command gives me back the following....'Could not get lock /var/lib/dpkg/lock resource temporarily unavailable' 'unable to lock administration directory /var/lib/dpkg is another process using it?'
I tried the obvious restart but that hasn't worked.
I've been running Samba on Gentoo as a PDC for a Windows XP domain for several years. We are using the IdealX smbldap tools to maintain users, we are storing accounts in OpenLDAP, and everything has been just golden for quite a while. However, for various reasons, we are migrating our servers away from Gentoo and onto Ubuntu 10.04 (64-bit). Unfortunately, replicating our Samba PDC/OpenLDAP backend on Ubuntu is kicking our backsides.I've got Samba 3.4.7 running. I've got OpenLDAP running. ldapsearch/ldapmodify/ldapadd all work correctly. However, when I try to mount a Samba share on another Ubuntu machine, I get...:
I have pidgin2.5.2. I want to install pidgin2.6.6.How can I do that?E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
I just found out that there are some weird files on my harddisk: they have a filename that starts with "._", have a size of 4096 bytes, and contain a string that sais "This resource fork intentionally left blank".Does anyone know what put them there?
I am working with a C++ program consisting of two threads. The first threads receives packets through an UDP unicast connection and stores them in a buffer. The second thread reads the packets from the buffer and sends them through an UDP multicast connection. Both use blocking sockets and share a common buffer and a linked list L1, which are protected by mutexes. The program seemed to work just fine, receiving a packet and sending it almost immediately, but started giving some trouble recently. The synchronization between both thread started failing, and I decided to use a non-blocking socket in the sending thread. As a consequence, sendto() doesn't work in some cases, causing an errno 11 (Resource unavailable).
New to CentOS5.5 I'm experiencing some trouble in order to continue my configuration. I've just installed my vmware tools and configured my network card with system-config-network
Edit eth0 (eth0) - vmxnet3 -> with a static IP I rebooted my server and since then I lost my eth0. I still see it in system-config-network, but I can't active it anymore.:
/etc/init.d/network start Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring. [FAILED]
A part of the disk space is unavailable: Only 37 GB out of 80GB is accessible A part of the disk space is unavailable: Only 37 GB out of 80GB is accessible. I have a vmware instance of CentOS setup with 80GB of Hard Disk space ( Preallocated). When I login to the system I only see 35 GB.
I have the requirement that if our website receives 20 or more requests within 60 seconds, to block the offending IP address for 5 minutes, then allow them access again. My only certain mechanism to do this is iptables. I wrote the following series of commands:
Is there a way of throttling a process resources, something akin to limits but for processes not users?ie I want processX to be restricted in the amount of memory it can consume. For process cpu I guess I can simply nice the process, but total memory consumption is my primary concern.
For some reason my mail server (Postfix) seems to have stopped delivering mail.
The error in the mail logs is "status=deferred (delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]: Connection refused) against all mails.
I have researched to try and find an answer, most information on this problem seems to point to a malfunction in the Anti Virus and Spam Filtering solution.
I have checked that Amavisd and Clamd are both operating and have restarted Postfix but all to no avail, squirrelmail is not working either.. ie not even producing a login page.
I have not changed anything in the config and am just wondering if anyone has experienced similar and could point me in the right direction of a solution.
Now I'm using Centos 5.3. when I let ADP (a EDA Tools) to idle more than 1 hours. The tools will display incorrectly. The per letter will be displayed as pane. So I must close it and re-open it.When the status is displayed, the system always said:xlib resource id allocation space exhausted!Forestall I use Centos 4.7, the system always works well. But I'm using Centos 5.3.How to maintenance it
Trying to complete a RAID 1 mirror on a running system and have run into a wall at the last part. I can't add the active physical disk to the mirror. This is on a Centos 5.6 x86_64 system. Anybody know where to go from here? I've tried adding the nodmraid line to the kernel boot line with no luck. Tried removing the logical volumes from LVM, but it won't let me. Not a Linux newbie, but haven't set up a RAID in a long time.

1) Write a C program using the fork() system call that that generates the Fibonacci sequence in the child process. The number of the sequence will be provided in the command line. For example, if 5 is provided, the first five numbers in the Fibonacci sequence will be output by the child process. Because the parent and child processes have their own copies of the data, it will be necessary for the child to output the sequence. Have the parent invoke the wait() call to wait for the child process to complete before exiting the program. Perform necessary error checking to ensure that a non-negative number is passed on the command line.
2) Repeat the preceding exercise, this time using the CreateProcess () in the Win32 API. In this instance, you will need to specify a separate program to be invoked from CreateProcess(). It is this separate program that will run as a child process outputting the Fibonacci sequence. Perform necessary error checking to ensure that a non-negative number is passed on the command line.i have done with Fibonacci sequence .but i dont know how to include tht fork() function and win32 api .any one can help to finish?
As part of my ongoing project I need to put together a messaging server of sorts. So far I have coded a server which accepts multiple connections, which then runs a function that will perform a task, see below.On this sever I have a global structure which is populated using the data found in a read() buffer. However with each fork() that runs the below function each process is handed a blank structure. How could I go about allowing each fork() child process access the same structure?
My code should hopefully show what I am trying to do? Code: void listen_for_client(int sock) {
Now,I created one parent and two children. I must create some value as random in child1 and child1 has to send these values to child2.Child2 must read them.. now,I cant create some random values and i can send them.But child2 doesnt work. I have two functions. One them is writing, another one is reading. Child2 uses reading function,but it doesnt work (child2 cant call it, because writing function in endless loop) What i must do? I used wait,usleep... No way.. I attached my file and also there is code..

I'd like to upgrade my 9.10 desktop to 10.04 but I can't get past step 1.I've done alt-f2 and issued update-manager -d, but no "New distribution" option is presented.I've clicked the "check" button and updated all my repo information but that doesn't help.I've done a wireshark trace and observed that the update-manager's requests get through the corporate firewall, and responses come back.Somehow it determines that no new distro is available.I'll explore further if someone could help me out with getting hold of the relevant update-manager source code.
