I'm out of ideas and I want to know if someone can answer me this question:I have 15 linux servers, with the same OS, on my network and I have to delete a user (the same in all the servers) but I don't have time to do it one by one.Some know a way to do this task
View 3 RepliesI am a non-root user, and have made a directory into which other users in my group can write. The directory is setgid, so files and directories within it have the same group.I can delete files placed into this directory, but if a user creates a subdirectory with files in it, I can't seem to delete those. Is there something special I can do (other than, say, bothering the user in question or the sysadmin about it) to get rid of this subdirectory?
EDIT: Inevitably, of course, someone asks "why?"The shared folder in question is a mercurial repository. We can't use a shared-account ssh-key-based server for this like mercurial-server, and we can't just host it externally for various reasons. But that part works fine.We use Redmine for project management, but it does not yet read the repo index for file contents - it reads the working directory. So the working directory must be kept up-to-datecrontab has been disabled by the sysadmin, so that's out. So I naïvely put a changeset hook in the shared repo that performed an "hg update". This seemed to work fine initially, until, of course, someone pushed a commit with a new directory. While I had vague thoughts of trying to make a setuid script for the hook, I'll probably just consider safer avenues.
I have a: debian squeeze(with last updates),sound system(Bose companion 5 USB) and Alsa Version 1.0.21. Sound system is work(good work) in:Ubuntu 9.10,Suse 11 and Windows But in Debian i have a starange problem:periodic sound is disappear(simply so or when i'm switch differents video files). It's not a problem with video players. /etc/init.d/alsa-utils restart(stop|start) not help. Remain only restart all system, but it's not always help.Sometime it's help only 3 or 5 restart time. Mother board audio card is disabled(in BIOS). Detailed about strangeness:
1 Variant: sound is disappear when i'm swich differents video files(simply video or online video).
2 Varian:When Debian is starting:sound eat in logins form(sound a drop),but at once sound is disappear.

However,overwriting existing files is still allowed (to support upload resume) . Ifyou want to disable this too, add -r (--autorename) .This is pretty much what I want to do, but I only want this done to ONE user on the server. I have many user accounts, but only one of them I want to prevent users from issuing the "delete" command and deleting everything.

Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.
View 9 Replies View RelatedI am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.
I can set it right by coping the hareware time to system time with this command:
Code:
hwclock --hctosys
I want to run a crontab to have that command run every minute. But it don't seem to run.

I'm here of course because I would like to know what would be the SSH command to issue if I need to delete certain files that meet certain criteria. For instance, in this case, I simply have files that almost bear the same name but still have some very minor differences.
Let me give you an example:
L0619000.log
L0619001.log
L0619002.log
L0619003.log
L0619004.log
Those in bold are those I'd like to have removed, while the "L0619004.log" is obviously to be left intact.
I received an alarm on a server stating that the /boot partition was 90% used. The partition contains several old kernels so I removed all but the current and previous 2 known stable versions using apt. This did not purge the files from the /boot partition.The /boot partition still contains the kernel files for 12 old versions. Is it safe to delete these files after the kernel has been removed using apt? Below is the output of the /boot partition.

View 2 Replies View RelatedI am currently in a project to set up an LTSP server with 10 thin clients. I am using Ubuntu 9.10 (Karmic).
Installing server and booting clients are working fine. Now, according to the need, I have to restrict user session numbers and allow resuming previous user session.
I have achieved to do the first one, but still could not able to setup the second one. As per requirement, if some thin can have power failure, the same session should be restored back. I am confused here, if I need to focus on saving xsessions or saving gnome sessions. I am looking for a concrete solution as I am running out of time.
Okay so I am a total newb to linux. I installed Ubuntu using Wubi and am trying to figure out how to get my wireless connection working. It occurred to me I may not have the right driver for use with Ubuntu for the wireless connection at my house. I couldn't find anything on the web to help..it appears I have a realtek RTL8102E wireless card in my laptop. I have absolutely no idea how to resolve this situation..I've looked on the web, but everythings pretty confusing. If I could get the wireless working it would be a good first step.

I'm using a fedora install mainly for audio work and have everything working well out of the box. My setup is simple:
-Direct cable from Guitar 1/4" > Sound Card input>Rakarrack Guitar Effects>Ardour>System Out
(Occasionally I put a synth/plugin like Zynaddsubfx or jackrack before or after rakarrack depending on what sound I'm going for)
-Jack for all audio transport with synthesizers
I have real time support with Jack and all other programs except Rakarrack. When I launch Rakarrack in the terminal, I get this message:
Code:
rakarrack 0.6.1 - Copyright (c) Josep Andreu - Ryan Billing - Douglas McClendon - Arnout Engelen
Try 'rakarrack --help' for command-line options.
Cannot lock down memory area (Cannot allocate memory)
Cannot use real-time scheduling (RR/15)(1: Operation not permitted)
AcquireRealTime error
However, running rakarrack in root does not display this output, and I assume it has no problem getting real-time scheduling in that case. I did some google searches but the only similar issues that I find are that people can't get RT support in jack except in my instance, I do have RT scheduling with jack, but for some reason I can't get it in rakarrack unless I'm root.
[Edit] I actually have to run jackd and rakarrack in root to get rakarrack to use real time scheduling. But, it isn't necessary for any other jack compatible program that I know of. I'm actually not getting any real time scheduling with any jack application, even though Jack is reporting to be running in Real Time. However, running everything in root fixes the issue even though I would prefer to not have to run as root.
I need to edit the system time as a not-root user. I am carrying out the following actions in my program.
1. Read the User Id of the process. User_ID= getuid()
2. Printing Capabilities(Permitted, Efffective, Inheritable)of the process
3. Setting UID = 0, using setuid(0)
4. Calling the prctl(), function to keep capabilities
5.Switching the UID from root to User_ID of the process
6. What we have now is a process with root capabilities as a non root user
7. On printing Permitted, Effective, Inheritable capabilities, I get the following
--> Permitted = 0xfffffeff = Effective
Inheritable = 0x0; with UID = 1001;
8. I then try and set the system time with --> system("date -s 10:00");
9. I get an error: date: cannot set date: Operation not permitted
10. I am unable to understand as to why I cannot set the time even thought the capability bit CAP_SYS_TIME in the Permitted and Effective sets are SET.

this idea to me right now seems stupid and impractical so I'm also looking for solutions outside of this one. I'm creating a set of highly available servers. They currently utilize pacemaker to manage a shared IP address, apache management, mysql management and also drbd handling. They currently replicate, properly failover and run fine. However, this is a shared web hosting setup and everytime a new user is added to the system a username and password is created and the httpd.conf file is updated for their site. I need a way to replicate those changes to the other server. For httpd.conf I'm pretty sure I can just stick it on the apache drbd resource and create a symbolic link. However, for the passwd and shadow files that is not a realistic solution.
