similar to: Deleting a KVM virtual machine from the command line

What am I doing wrong here? I need to be able to write to /var/cvs. This used to work before I moved these groups into an LDAP directory instead of /etc/group: [scarolan at watcher:/var/cvs]$ touch test.txt touch: cannot touch `test.txt': Permission denied [scarolan at watcher:/var/cvs]$ ls -ld drwxrwsr-x 4 cvs cvsgrp 4096 May 18 2008 .

Hi, Until today, I hadn't found a way to cleanly remove a KVM virtual machine through command line on CentOS 6 or 7! I had to run 'systemctl restart libvirtd' or 'service libvirtd restart' After several months (!!!), I found this thread: https://github.com/pradels/vagrant-libvirt/issues/107 Now, I know how to cleanly remove a KVM virtual machine (with default file location):

I'm up for a cell phone contract renewal and am considering upgrading my handset. I looked at some devices at my local AT&T store but nothing really jumped out at me. I'm particularly interested in a cell phone that has a reliable ssh client, with ssh-agent and public key authentication abilities. Those of you who administer systems remotely, what mobile ssh client do you recommend?

I have a server that is undergoing some patching soon and would like to make note of any files that have changed after the patching is complete. Can you recommend a tool that uses md5sum snapshots to do a quick before and after test, showing anything that's changed on a particular file system?

Has anyone had any luck deploying rails apps in a Linux VM image on a production MS Server 2003 with IIS ? If so which image did you use a a base? I am currently using a Gentoo image and have installed ruby and rails but after performing a rails testapp and running webrick with ruby script/server I get a page timeout when trying to visit http://0.0.0.0:3000or http://127.0.0.1:3000 and I get no

I really like gnu screen and use it everyday but there's one thing that is a bit inconvenient, and that's the odd line wrapping and terminal size issues that seem to pop up. The problem crops up when I type or paste a really long command, and then go back and try to edit it; the text starts to wrap over itself and you have no idea what you are editing. Any fixes for this?

I have a perl script which runs from a cron job. How would you limit the amount of RAM that this script is allowed to consume? Is there a ulimit setting that will accomplish this? If so does ulimit have to be run each time the script is run, or is there a way to set it permanently?

Can anyone help make sense of this? This is an ext3 partition. It's only showing 403GB out of 426GB used, but then it says only 632MB available? Where'd the extra ~25GB go? [scarolan at server]$ df -H /disks/vrac5 Filesystem Size Used Avail Use% Mounted on /dev/sdb2 426GB 403GB 632MB 100% /disks/vrac5

I would like to block all DNS queries that come from one particular ip address. I used TCPdump to verify that the queries were in fact, coming from this IP: [scarolan at server:~]$ sudo tcpdump -n udp port 53 and src 10.100.1.1 tcpdump: listening on eth0 11:12:17.162100 10.100.1.1.19233 > 10.100.1.61.domain: 14270+ A? server.domain.com. (32) (DF) Could someone help with the proper syntax

Is there a flag for the df command to get the total disk space used on all filesystems as one number? I have a server with a lot of mounted shares. I'm looking for a simple way to measure rate of data growth across all shares as one total value.

Hi, I'm currently fiddling with Samba, trying to make it work on CentOS 7. Before that, I ran Samba successfully in a mixed environment with Slackware64 14.1 on the server and Slackware/Windows Seven on the client side. I have three sandbox machines running CentOS 7. One has a minimal install with only the samba and samba-client packages. Just to be on the safe side for fiddling,

I'm attempting to block access to port 53 from internet hosts for an internal server. This device is behind a gateway router so all traffic appears to come from source ip 10.100.1.1. Here are my (non-working) iptables rules: -A RH-Firewall-1-INPUT -s 10.100.1.1 -m tcp -p tcp --dport 53 -j REJECT -A RH-Firewall-1-INPUT -s 10.100.1.1 -m udp -p udp --dport 53 -j REJECT Further down the

I have an odd situation here, maybe one of you can help.? We have a script that runs via a cron job.? It's purpose is to decrypt PGP-encrypted files in a certain directory.? I have tried the command two different ways, both fail with the same error message: gpg --decrypt $file > ${file%.txt}.decrypted.txt gpg --output ${file%.txt}.decrypted.txt --decrypt $file (Don't even ask about

I'm having trouble getting the GDM login screen to show up when I connect from a remote host. I'm using Xming on the local Windows machine, but every time I connect to the remote server all I get is a gray window with the X cursor. I have "Enable=true" in the [xdmcp] section of /etc/gdm/custom.conf. IPtables is disabled. I've googled around and read through the xdmcp page

We have a directory full of installation and configuration scripts that are updated on a fairly regular basis. I would like to implement some sort of version control for these files. I have used SVN and CVS in the past, but I thought I'd ask if anyone can recommend a simple, easy-to-use tool that would be better than cvs or subversion for this fairly simple setup.

I have a large (1.5TB) partition with millions of files on it. e2fsck has been running nearly 12 hours and is still on "Checking directory structure".

I have a string, "2012_10_16"; let's call this $YESTERDAY How can I rsync a file tree from a remote machine to the local one, including *only* filenames that contain the matching string? I've read the man page and googled around but can't seem to get the syntax right. I either end up syncing all the files, or none of them. Here's how the code looks now (I will remove
