General :: Starting VNC Upon Boot-up Using Specific User
Oct 27, 2010
So right now VNC is starting a session using :1. When I connect to that session, the terminal is logged in as root. I'd like for the terminal to be logged in as a different user as some of my end users are going to be using this and don't require such privileges. I found that I can "su" to a different user and start a new VNC daemon on :2 and when I connect to that session, the terminal is logged in as that user. What I want to do is get that to run at boot-up.
I have a need to run a specific app as a specific user when the machine boots into init 3. I can not run this as root so I need to specify a user. Can someone tell me how to accomplish this?I usually have to log in and start this application by typing check -D which starts this app and daemonizes it. I want to be able to run that at boot with my normal user not root.I hope I explained this correctly.I have added it to rc.local but it runs as root.
I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.
I deleted some files on the command line and would like to learn if it's possible to recover them. It's not a terrible thing if they are gone, but I want to see what I can do. The server is configured as a hardware RAID5+1 (ext3, Debian Stable) and I *really* don't want to take a dd of the entire disk.
ls -id gets me the inode value of the directory(155655)
I'd like to create a disk image starting at that specific inode. Then there is the issue of picking an outer boundary of the disk image. I'm hoping there's a dd/ext3 genius out there to advise.
Im writing a script that extracts part of the path name:I drop a file in terminal and set the directory name of the file to x using dirname $0note: ( directory is different every time since not all files are from the same location)
ex. x="/home/Downloads/yesterday/photo/.../image.png" /image.png /.../ means I dont know the name of folders between but I know the path name always starts
A function by name abc is called in many files. I want to copy all the lines with the function call to an output file.A simple grep on function name doesn't help me as the function call is spanning across multiple lines as follows:
abc(parameter1, parameter2, parameter3);
So I want to copy all the three lines (till semicolon) to the output file.The problem is because there are more than 200 calls for the same function and I cannot do it manually
How do I give permission to a logged in user to stop/start a specific service without entering a root/sudo password? So they can do a simple "service SomeService stop|start" It is for a headless Ubuntu server.
my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)
I am looking for a way to deny telnet and ssh to one specific user. So far I've only tested with telnet and my attempts have been limited to various hosts.deny entries:
None of these work. The only thing I've found that does work is:in.telnetd : IP_addressBut this is only a semi-viable solution because we will soon have multiple logins for the one username from different servers and sub-nets. Ideally, I'd like to be able to deny telnet and ssh access to this username regardless of where the login originates. I suppose it would be possible to specify each server IP, but that'll be a bear to maintain
i have created a file (by root user) called test.txt. Then i created a user bob. Now i want only bob to read/write/execute this file and no other user shall have any permission on it.
I run the openssh daemon on port 22 and have the proftp running on port 21. I would like to block SSH for a specific user.I use proftpd.I would like to prevent the SSH access for this user and leave the FTP working for this user specific.Into /etc/passwd, I tried to change the /bin/bash to /bin/false, but this blocks both SSH and FTP access for this account.
Im trying to add users to my nfs server with a specific home directory that already exists. Can this be done? I've done some research on google and other forums but cant seem to find the answer.
I did some digging on the sudo command and I do know the config file is /etc/sudoers Read the manual for sudoers and found out that I must use visudo to edit the file I read some of the examples at the bottom of the file and tried entering my own account in following the example. one of the commands I was trying to allow my account to perform without root login is the mount command So I tried adding this in (kreid8 /bin/mount ALL) I then saved & exited the file and logged out of root and tried sudo mount -t vfat /dev/sdc1 /media. I got an error saying I had to be root in order to do that But when I use the visudo -l option it shows that I have that privellege. Did I edit the file incorrectly?
I have two machines between which I need to share a folder.On server1, I have the user 'appuser' that needs to access (read/write/delete) on this share.On server2, 'root' accesses this share and writes to it.I have the following in /etc/exports on server1:/home/app-share 999.999.99.99/28(rw,insecure,sync,no_root_squash)where the number is the IP address. How can I change this to allow 'appuser' access?
allow specific user permission to read/write my folder
I have a folder called /TAR/Sketch
I added a new user, named Snoopy, I want to grant this user the ability to add files & directories to this folder which is under the group Sketches and the owner is me.
How can I mount a device with specific user rights on start up? I still have some problems figuring it out. I would like to mount the divide with uid=1000 and gid=1000. My current entry to the /etc/fstab/ file looks like this:
Can advise if I want to have a alert message when a specific user is login to the system , what can I do ? that mean if a specific is login to system then send me a alert message ( by any way ) to inform me the user is login , what is the method ?
I'm trying to do something like thisi created a group called www and made this group the owner of the directory/var/www/htmlso i can read and write to it.of course I've add my self to this group, but it seems i can't read and write.the syntax i used was something like chown :www /var/www/html.didn't workonly when i used chown samurai:www /var/www/html i could finally could create new file.the reason i don't want to specify the user name is because I'm thinking of a scenario when i need to give permission to a large group of ppl and don't want to do it user by user.
I am using CentOS 5.5 and I created few users (useradd john etc.) and now I want to assign privileges to this user on some directories and files in those directories. For example I want to give read privileges to directory "/documents" and all of files under that directory.
I have a workstation dedicated to monitoring. The goal is to have multiple web sessions and other applications running across dual screens on multiple virtual desktops. I have a nice Perl/TK/wmctrl script that will automatically rotate the desktops. All is working great.
The problem is, I need a solution to automatically start the applications on the correct desktop, with the correct window size, in the correct location on the desktop. That way we can start the monitor boxes in the morning and have everything start in the correct place. It is a really cool effect to have wall mounted monitors with cube rotation showing off multiple graphs and more.
Do any of you pros know how to start an application with a specific window size and define where on the desktop it is placed? The box is running OpenSUSE 11.4 KDE. Is that kind of control possible?
I have Ubuntu 10.10 installed on my pc with XBMC installed. It's set to boot into xbmc on start up and works fine. I also have squeezebox server (a music server for my network) installed and again don't have any trouble. I'd now like to get squeezeslave running, a client for squeezebox server so I added the following lines to /etc/init.d/local:
I am having a Lenovo Thinkpad SL400c laptop running on c2d (64 bit) processor. The problem is, Linux Mint doesn't boot in this laptop but boots well in other laptops( I tried it in dell inspiron and compaq ones)and desktop. I tried all versions (from Linux mint 7 till 10 and both 32 and 64 bit versions). What actually happens is that, the BIOS loads the CD (doesn't even asks "press any key to boot from CD" as it asks for Windows) and abruptly results in a blank screen. It remains blank even for hours. But Opensuse, Ubuntu, and even open solaris all run fine on this system. Don't know why it resists only Linux mint.
I am working as a Linux administrator in a very small data centre with 5 servers with following routine tasks.
1. Managing SAMBA shares and giving user specific access for the shares. 2. Scheduling backup of some mount points with rsycn to store data in remote hard disk 3. User and group administration, with sudo access. 4. Creating and Managing Xen Virtual machines and giving access to other project teams. 5. Automating some tasks with Shell Scripting. 6. Managing FTP server for user uploads.
I have practiced a lot in my home laptop without RHEL training, Cleared RHCE and LPIC1. I want to do some advanced system admin tasks, but do not have option in my current data centre. With Above skills is it possible to get a job ?
I would like to create an alternative booting possibility in my GRUB menu that does not start some services (listed by chkconfig) like cups.
I would use this boot during travel where I surely does not need these services and shorter bootup time is preferable. Permanent removal of such services is not an option because I could not miss them during normal daily work.
i wanted to know how can I make my programs or script automatically start at boot time ,for example if I restart my server at any time they start at boot time automatically with no need to any body to start them.
I'm using RHEL 4.6. auditd was set on for run levels 1-5. I changed something (?), now my system won't boot. It hangs on "Starting auditd:". I tried adding "enforcing=0" to GRUB. I tried adding "selinux=0" to GRUB. I tried adding "auditd=0" to GRUB. I've tried them separatly, as well as, in various combinations. I've tried entering "I" to go into interactive mode but, I'm not fast enough to hit that millisecond window. How can I skip/get pass the "Starting auditd:"?
