CentOS 5 Server :: Writing Init Script For Wrapper - Start As Root Run By User
Nov 27, 2009
I have installed the Apache Directory Server (ApacheDS) Now I need a iniscript that startining the App as Root, so that it can use the Port 389. After them a unprivileged User (apachds) should run the Service. The same solution I am searching for Glassfish. What can I use for them? RHEL and compatibles doesn't have a start-stop-daemon like Debian.

As root, firefox shows that no plugins are installed - does not see flash-plug. For the other user the flash-plugin is there however it only load for the first instance and then will only start again if I reload the page.
Yes I am new to Linux - I have just installed Centos 5.3 and via yum install adobe flash-plugin - lots of searching on the web to get this far.

Basically I have a USB flash drive currently formatted under vfat. I can log in as root and the system automatically picks it up and automounts the drive successfully. What needs to happen is that a non-root user needs to be able write to this device while root has mounted this device. Due to other program constraints, I can not mount the device using another user so I have to do it with root.

I have inherited ownership of a Debian server process that logs its error message to stdout/stderr. Currently its initscript has lines like:
start-stop-daemon [options] --exec $DAEMON -- $DAEMON_ARGS < /dev/null 2>&1 | logger $LOG_OPTIONS 2> /dev/null &
I have tried to abstract as much of that away as possible. The options specify a pid file, to make a pid file. A subsequent line tries to establish whether the process is up, though I think several conditions are not checked for. This script seems pretty ropey to me. I am trying to start again with the lsb-base one in /etc/init.d/skeleton though that is going to require a lot of modification. get the code change to use the syslog API however that is out of the question at least for now.
1.) Create a named pipe
2.) Start up a logger daemon that reads from the named pipe
3.) start up the server process that writes to the named pipe
It would be ideal for this if start-stop-daemon offered options to specify where the IO of the daemon process should be redirected to. However I am not about to offer to adopt that package (with ~400 bugs) so I doubt that will happen. Trying to specify the redirection on the command line does not work. In the case of the logger daemon start-stop-daemon seems to hang on the system call. In the case of the server process the pipe gets closed when start-stop-daemon exits, so the logger daemon exits. None of that seems surprising.So what I am doing now is to write simple wrapper scripts for the server and logger processes. Both wrapper scripts have this structure:
1.) sanity check the arguments
2.) exec program [suitable redirection of IO]
Then the start-stop-daemon can call the wrapper scripts as daemons. From my experiments so far this seems to work. However I feel a bit uncomfortable with this. It introduces several new wrapper scripts.I cannot think of any obvious security holes but I suppose race conditions are inevitable.

I wrote a custom init script for a java application. The script resides in /etc/init.d and follows the convention for the init.d scripts. However, the script runs the java process as root. I need these processes to run as a non-root user. Is there a way besides using sudo or su in the script (seems inelegant), to run the script as a specific non-root user? Perhaps using a .conf file in /etc/init or a daemon wrapper? What would the Ubuntu way of doing this be?

I'm working to make guest OS run as no privileged user. I've found a script made by an Italian guy that should start the guest instance during boot. Unfortunately the script was made for Debian and as I'm not confident with bash, I'm having some difficulties in making it work under RedHat 5.3 launched as root
vbox-ithaca start
vbox-ithaca: line 116: log_daemon_msg: command not found
sudo: VBoxManage startvm ithaca --type vrdp: command not found
vbox-ithaca: line 119: log_end_msg: command not found
these errors to me basically say that those commands aren't in PATH, but I couldn't find them anywhere

I installed Centos 5.5 on a home PC to be used remotely.
All server daemons work fine but only start if the user is logged in.
How do I set the SSH server to start whenever the PC is turned on, rather than when the user is logged in? I read the chkconfig man page online but couldn't find anything.
Plus I put a script in my startup services to be run whenever the computer boots (I'm guessing when the users logs in). How do I go about setting that to run too whenever the system boots instead?

I had a LiveUSB of CentOS 5.5, so I decided the install it.With no installer,I just copied the files to my hard drive.his was in a multi boot with Windows 7, Ubuntu 9.10, and FreeDOS.I updated GRUB2 and it detected CentOS. I loaded my entry and it failed to mount the root filesystem.I took the initrd0 file from the LiveUSB syslinux folder and added that ramdisk to the entry. Now it finds the root filesystem (/dev/sda9 as Ext3).But it fails shortly after loading /sbin/init. It talks about an init error where it says "File not found!!!".The previous lines involved umounting old filesystems, like /dev.

I have two ubuntu servers. I have upgraded them to 10.04. Now I have serious problems at startup: iscsitarget and heartbeat scripts do not start all the times I reboot.I have installed monit to try to start iscsitarget and heartbeat and guess what? It does not start too at boot.In one of the two server sometimes it also starts with ethernet cards swapped.

I just installed the ventrilo server daemon on CentOS 5.3 and I'm having 2 issues with the init.d script I wrote. Issue 1: the stop command does not work. I suspect due to an issue with where the daemon puts the pid file. Issue 2: chkconfig says that the "service ventrilo does not support chkconfig". The script is below.
#!/bin/bash
# ventrilo server
# Pull in init.d functions
. /etc/rc.d/init.d/functions
VENPATH=/etc/ventrilo
VENBIN=/usr/bin/ventrilo_srv

I'm not a database guru, so be patient with me: Is there some kind of "wrapper" software you can put around an SQL database (MySQL perhaps) that allows you to internally configure database rules on a higher level than the database itself can actually implement? (E.g., "rows in table A can be deleted, but only if there are no related rows in table B and only if column x for the row in table A is in state y.")The idea would be to keep from having to trust this kind of logic to the client programs, while also avoiding the need to write a full fledged server daemon just for your application. The clients submit their SQL insert requests to the wrapper daemon, and the daemon passes them on to the database if they pass a rules table defined for that particular database.

I did a NMAP on a 10.4 desktop system. Found tcp wrapper on my system with an open port. Again I do not run a server. etc/host-deny and etc/host-allow contain no active elements. I know tcp wrapper as a great tool to secure a server. Closing the port with ufw gives no result, tcp wrapper still show up.

I'm trying to get Xorg running on a Dell 2850.I can't get it to work.I installed xorg-x11-drivers via yum, and used both "Radeon / ati" drivers, including the default vesa.
Here are the main errors (error log file attached):
Could not init font path element unix/:7100, removing from list!
(**) RADEON(0): RADEONSaveScreen(2)

and at the end it says:

I am going to remove root access via SSH which seems fine but I don't know how to add a new user, do I have to create a group first or are there existing groups I can add a user to, and does it matter which group I add a user to if I want this user to have root access with sudo?

I'm configuring a new Centos 5.5 server in replacement of an old W2K server.The topology of our network is simple : one file/dhcp/dns relay server and workstations (PC's and some MAC's) plus network printers and scanners.All the workstations have dynamic IP addresses (easier because a lot of 'dynamic' changes : new persons with their own laptop, ...) and the server and printers/scanners have fixed IP addresses.I edited the dhcpd.conf (see here underneath), I have the file dhcpd.leases but it doesn't start !

I forgot the root passwd for linux (via the "single" mode) and, according to all confirms, did so successfully! I then try to log on to Centos as root, and I can't....it says "incorrect passwd"! So then I log on as another, regular, but not root, user, with that passwd, and boot up into Centos. if I try to "su" to root, with the new root passwd, again it says its incorrect. there is no "system admin" passwd set. I checked!. I need root access within Centos!

I'm running a server with CentOS 5 where the software that needs to run on the server uses ifconfig to verify the system IPv4.The problem is that /sbin isn't set for the user that is supposed to run the software (sadmin) which means the software can't execute ifconfig and thus terminates.now the workaround I've been using is simply to input.

Can someone assist me with recovering/resetting the password for Root via Single User Mode in CentOS v5? I've modified the kernel line using Single, S, and 1 but it appears that these commands are being totally ignored as the server continues with the boot process and displays the GUI logon screen. The server in question is a VM box running on ESX v3.5 U4. The person that created this VM is no longer employed here and I've exhausted everything I know regarding Single User Mode.
