I have been trying to set up an LDAP server for a development environment as part of an internship for a week now, and I cannot get past this point. I have been following the 10.04 server guide to set up LDAP here: URL...Once I get to the following point in the guide, it just hangs:"As an example of modifying the cn=config tree, add another attribute to the index list using ldapmodify:"I've been working on this for a week and can't understand why this won't work. I am fairly certain that I've followed the guide to a 'T.'Any idea why am I receiving a permission denied error? Is this a permissions issue with one of the config files?
We have a COM Express carrier board with Intel Atom processor.What happens is COM board issues a reset signal every 3 sec.I am not sure whether its entering BIOS or not..I could not hear any beep..It is difficult to probe the POST error codes on port 80 in this board.And there is no way for display also..Is there any fatal errors where BIOS resets the CPU..?..As far as I know it just halts on encoutering a fatal error..
I've scanned my computer (I'm using Ubuntu 8.04 Hardy Heron) and ClamAV has issued it has found a virus called Exploit.PDF-9669. What seems strange to me is that such a warning always happens (or, at least, in the most cases) in the same folder tree "sys" and ClamAV issues the very same virus/malware warning (Exploit.PDF-9669).
An example: sys/devices/virtual/vtconsole/vtcon0/uevent: Exploit.PDF-9669 FOUND sys/devices/virtual/net/ppp0/address: Exploit.PDF-9669 FOUND sys/devices/virtual/net/ppp0/broadcast: Exploit.PDF-9669 FOUND sys/devices/LNXSYSTM:00/device:00/uevent: Exploit.PDF-9669 FOUND
My ClamAV version is 0.94.2/10275/Fri Jan 8 22:06:46 2010. It has been not updated since I installed Hardy in my computer last year. Is my computer in danger?
I am having a weird problem here. The open programs are closing secretly without giving any indication or issuing error. For example I open couple terminal and some minutes later I look at my screen, boom they are not there anymore. This issue is not just limited to terminals, other gui apps suffer from the same thing. Does anyone know if any program or service would do such a thing?. I am scratching my head here to figure out why that is the case It just started happening today.
We are experiencing problems copying files from a server to server where the machine issuing the copy is a 32-bit lucid and the mount drive is a 64-bit server. I have no other information but the md5's are consistently different after doing a copy. The files are > 8mb.
I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
I am using openSUSE 10.3.When I install software from tarball then to record time required I send output of date to beg.txt(when installation begins) and end.txt (when installation finishes).How can I append output of date to a file so I don't need two files?
I want to be able to use Ctrl+R to have reverse-i search. Also if I press Shift+Up Arrow after typing the first few characters of a recently executed command then the shell should complete the command by finding the most recent commmand having the same first few characters.
Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?
When you run the following cp command in the BASH terminal, how does Linux know which files are the source and which are the destination when copying multiple files from one location to another?How does Linux know that the services, motd, fstab, and hosts files are the source and the /home/fred/my_dir is the destination?This question came up in a Linux class and I was not sure of the answer. I was thinking it is based on the source path entered ending with a file path and the destination being a directory, but was not sure.
i'm trying to redirect the output of a command to the input of the next command. not sure if i'm going about this the right way. an easy method would be just to store the output of the previous command in a file and redirect input to read that file, but i'm curious to see if this can be done without writing to any files.
Up until now I've been using plink to remotely compile a project I'm working on. But recently the administrator from the remote server updated the distribution and messed up some configurations. My project has a lot of scripts written for tc shell (tcsh), and now the default shell is bash. There is no way to change this. Another problem is that now I need to run newgrp to change my default user group.
So... to work around this problem I've changed my .bashrc to run newgrp and then tcsh. If I do a normal connection using SSH, everything works as expected, but when using plink, or SSH to remotely execute commands, the shell gets stuck on the newgrp command. I think it's because both applications need a return value from newgrp to send the command I need to execute. Remotely running scripts that call a shell also get stuck like newgrp (newgrp also opens a new shell and that's why it gets stuck) my .bashrc is as follows:
Code:
user_grp=`id -g` if [ $user_grp != 4919 ]; then newgrp new_group_id else

I have a script which builds a project and then runs junit tests. However, if the build fails, the junit tests fail with the same error message.Therefore the command which runs the junit tests should only be executed if the build was successful.
I want to run gsettings list-schemas (which return a list of about 100 names separated by spaces)and somehow direct each name one at a time as the input to this command:gsettings list-recursivelyI've tried it with awk, and standard | piping and also as a string variable strvar=$(gsettings list-schemas) and using the $strvar as the input butam missing something in between I'm sure like for - while or proper syntax of awk etc
I want to use the output of a previous command as a parameter to another command. For example: to know where "nice" is stored i typed: which nice output: /usr/bin/nice now the second command i typed is: ls -l /usr/bin/nice Is there a way to have a single command like: ls -l which nice ?
I have a file and it has some content . Now I want to check for some text in that file and if does not exist I want to append it . So I need to first grep and then do "echo "content" >> s.txt" . Is there any way to execute this two commands in a single command .
Im not getting able to neither add new users using command useradd nor delete existing users using command userdel. And even Im not getting able to login into any existing users except root. It was ok before. Im having this problem very recently on my linux server. Im using RHEL5.
I'm timing how long it takes to run a command foo. I'm looking to append the results from the time command to a file, and discard the results from the foo command. I tried the following, but it didn't do what I want:
$ time ./foo > /dev/null >> output_from_time_command.txt
