I get option to SUSPEND/HIBERNATE or reboot/shutdown. Isn't there something similar to locking as in windows.I don't want to log out each time I want a break(think bathroom, drink).I would expect that after I have LOCKED the workstation, I would have to log back in.

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.

I'm writting a program that uses a USB webcam. Sometimes the program crashes and exits, but sometimes it crashes and becomes a zombie process, which I can't kill even with -9/-KILL signal. When that happens, all access to th USB webcam is totally interrupted and all attempts to communicate with it fail.I'm looking for a way to either force this process to terminate or to at least make it release the webcam so I can use it again. So far, the only way I've found to regain control of the camera is to reboot

I have a startup script placed in /etc/init.d wherein I make the following call:
nohup sudo -u myuser $CATALINA_HOME/bin/startup.sh 2>&1
This causes Tomcat to be run as myuser, which is expected. However after issuing the reboot command the system starts up and root is now the owner of this process. How can I force the process to be started off as myuser on reboot?

I am currently working on a Diskless Fedora10 based PXE image that should auto login and then launch the ICA client without launching the desktop (so normal autostart will not cut it)I have got the image up and running, the clients boot correctly, autologin etc, but still launch KDE, and I was hoping replace the desktop with the ICA Client.

I've asked this question more or less before on stackoverflow and believed it to be solved (hence accepted the answer) but it turns out it wasnt solved.In simple terms, I've written a python script which just outputs text constantly to stdout, thats all it does 24/7. I've linked it to this xinetd file

I have been trying to locate a good ftp client for an RHEL 5 server. The vsftp client has been locking up hard whenever there are slight network hiccups. Ideally we would like to look at something that works along side the vsftpd daemon. I had hoped that one of you could make some recommendations. This a 2.6.18-53.1.4.el5 kernel and we are running version 2.0.5-10.el5 of vsftpd, I have been looking around but cannot seem to find either a standalone client or a build that indicates that the bulid is compatible with RHEL 5.

i want to disable all DHCP request, can i turn off the client that if a MAC address changes a dhcp request is not automatically made?reason for this: I have HP blade running with an Intel NC260M mezzanine card running with virtual connect. I have experienced problems with firmware levels with this card where the virtual connect mac address is ignored and the real MAC displayed. As we are using bonds on the servers and have 6 NICs installed we have to tie down the MAC address to a bond. A blade was replaced today without the firmware update and the real MAC appeared, a dhcp request was made and my-eth[2-3] and resolv.conf files were over-written by the dhcp supplied

Is there a way for wget not to download a file but rather just access it? I use it to access a URL that triggers a process on a web server, but the actual HTML file at that location doesn't need to be downloaded and saved. I couldn't find anything in wget's help to show if there's a way to do this. Could anyone suggest a way of doing this?

I have a high priority service that I start with sudo nice -n -10 process. This process does not need superuser rights though, except for the priority elevation. But nice requires superuser privileges to elevate priority.

Code:
#include <stdio.h>
#include <unistd.h>
#include <signal.h>
[code]....
Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.

as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.

I am connected to a server with openvpn. When I try to get a file from this server to my workstation, then the error appears : ssh: 2011-04-28_10: Name or service not known
But in fact the name of the file is :
2011-04-28_10:26:45
I guess the system can not handle the time indication in the filename ?
Escaping it with does not help apparently.
