  • 'Auto' option missing for TreeView subclass

    - by Jared
    I've created a custom control that subclasses TreeView. Right now it's completely empty, doesn't override anything. However when I place an instance in the designer the 'Auto' value for the Width and Height fields is no longer available as it is with the default TreeView. What am I missing?

  • How to execute a command on multiple hosts using IPv6 only?

    - by math
    First of all there is pdsh which is essentially a parallel distributed shell which may execute commands on a list of given hosts. However, I find myself in an IPv6 only problem setting. It seems that pdsh is not able to use IPv6, as I am getting error messages: pdsh -w ^hostnames my_command pdsh@myhost: gethostbyname("foobar") failed I also tried to use IPv6 addresses only, which also didn't work. So how do you run a single shell script for administrative purpose (no SGE stuff, or similar) on a bunch of hosts that is IPv6 reachable only?

  • Config deployment on multiple servers.

    - by user66601
    I have multiple servers in WEB cluster (identical configuration for all of them, despite the IP) How do you deploy changes in configs on multile servers? I make the new config, then create config per every server (placing correct IP), and next: upload them on every server, replacing old ones (rsync over ssh) set on every server a job which reloads webserver at the same time (servers use ntp). - this done by issuing commands by script (to save time for logging in) before adding a job for server reload - there's checksum test of the config on the server) - an a notification in case of fail How do you see such method? What should be the "professional way :) ? (I don't say my way doesn't work... it works and saves my time not used for logging on every webserver.) Regards,

  • Why does deleting from the command line take significantly less time than from a GUI?

    - by Jordan Plahn
    So this is probably the dumbest question you'll read today, but it's something I just wondered about as I was deleting a dozen or so images from my computer. With a quick rm -rf command on the directory's contents, all the images were gone in a snap. When I drag the same dozen or so images to a trash can/recycle ban, it takes sometimes 10 seconds or more. Now I'm sure some of it comes from the overhead of the GUI and such, and some of it may be the fact that the file still "exists" in some form if it's put into the recycle bin, but is there anything else that accounts for such a huge time disparity? Are "rm" and "delete" just such fundamentally different commands so I'm trying to compare apples and oranges? Enlighten me, please!

  • Ubuntu from console/command-line/shell

    - by Xolve
    Earlies linux distros though required lot of manual work they were quite good to use from commandline. If the X-server didn't start or you just want a shell to work they all supported. Network was configured by init; sound was up and ready; new devices inserted would be configured and their configureation was placed in fstab. Also there were small scripts I found on many distros which on X used windows while on console they switched to ncurses. But now this all needs GUI with a desktop manager (KDE, GNOME) for the new paradigms :'-( require GUI (NetworkManger, hal etc.). So if on just command line you have to be root, looks like they believe only geeky admins need that, and need to edit config files or type big commands. Any way so that this is easy in Ubnubtu through shell again.

  • Why would anacron not be running?

    - by Rory
    I have a Ubuntu system that has anacron installed. However I'm pretty sure it's not running. It's not running the commands in /etc/cron.daily to rotate the syslog files (I'm using sysklog, which has its own rotating log method, not using logrotate). The last time the logs were rotated were in October 2009. /var/spool/anacron/cron.daily exists and the contents are 20091015. AFAIR we had a power outage then, and everything rebooted. How can I debug anacron? How can I see why it's not running? My first instinct is to look for /var/log/anacron, but that's not there. How can I fix it to make it run again?

  • Nagios remote monitoring: NRPE Vs. SSH

    - by sam
    We use Nagios to monitor quite a few (~130) servers. We monitor CPU, Disk, RAM and a few other things on each server. I've always used SSH to run the remote commands, purely because it requires little to no additional config on the remote server, just install nagios-plugins, create the nagios user and add the SSH key, all of which I've automated into a shell script. I've never actually considered the performance implications of using SSH over NRPE. I'm not too bothered about the load hit on the Nagios server (It's probably over-speced for what it does, it's never been over 10% CPU), but we run each remote check every 30 seconds and each server has 5 different checks performed. I assume SSH requires more resources for each check but is there a huge difference? (I.E. enough of a difference to warrant the switch to NRPE). If it's any help, we monitor a mix of physical servers (Normally with 8, 12 or 16 physical cores) and Amazon EC2 medium/large instances.

  • persistent view controller

    - by derrichh
    Im building an iphone radio application and I want to have the controls, play, pause, stop, etc. in a tool bar (a custom view controller) at the bottom of the application. I want to keep this there throughout all the views so you can control the audio while navigating through the other parts of the application (multiple view/table controllers). Is there a way to create a view that stays in place like a tab bar?

  • Where should I keep my log files?

    - by ripper234
    We keep most of our logs in a dedicated database table. We have written custom appenders for log4j and log4net, have a fixed log schema with lots of handy columns, and are quite happy with it. Is that the "best practice" (for sites smaller in scale than Facebook, where a simple DB table just won't scale)?

  • oracle virtualbox doesn't work for host Kubuntu since Lucid Lynx 10.04

    - by 13east
    I have a thinkpad edge 14 core i3 2.4 ghz and 4g ram; I have tried kubuntu 10.04, 10.10, 11.10, 12.04 and 12.10 (all x64 architecture); Both oracle and ose virtualbox only works properly to install XP and windows 7 quest system on kubuntu 10.04; For every other kubuntu release since, the guest installation goes as far as formatting the virtual drive, freezes at this step, and doesn't even go as far as copying files to hard-drive to begin installation. But virtualbox has not stopped responding to commands; I can kill that one specific window with the problem installation ("machine" - "close" - "power off the machine") and start over again without having to force-kill virtualbox application. If anyone knows how I can go about addressing this problem, any help you can provide would be very much appreciated. Thank You.

  • Vim: What do these short names / verbs like <leader>, <C-r> mean?

    - by Ambidex
    I'm using Vim for a while now, starting to like it more and more. But when searching for some new features that Vim has in it's goodie bag, I'm often slapped in the face with things like <Leader> <C-r>, etc... I'm feeling really stupid for not being able to relate these to keys, commands, or what soever they should mean. I've also been searching multiple times for the use of these verbs, but I think I'm not using the correct search queries to get to the right explanation pages. Could someone give me a push in the right direction or maybe summarize the meaning / workings of these verbs? I thank you in advance!

  • Why does MOVE command in DOS treat wildcard patterns oddly in this case?

    - by Adisak
    I am using the "move" command with a wildcard pattern in the CMD prompt under Windows 7. In my source directory, I have the following files: movie1.avi movie1.avi_metadata movie2.avi movie2.avi_metadata If I type the command move source\*.avi dest it will move all four files even though I would expect it to only move the two *.avi files and not the *.avi_metadata files. As expected, move source\*.a dest and move source\*.av dest don't move any files. However when the length of the extension for the wildcard pattern is 3 characters, it will move all extensions that begin with those first three characters. Is this a bug in the "move" command or expected behavior and is it documented anywhere? Edit: John Watts notes that this is probably do to "short" filenames. Is it possible then to make commands in the CMD interpreter only operate on long filenames and to ignore short filenames?
