  • Steps to diagnose performance bottlenecks on Mac OS X

    - by Dave Cahill
    If you wanted to track down performance issues on a machine running Mac OS X and find out what was causing slowdowns, which command-line or graphical tools would you use, and how would you use them? I'm interested in advice on the best tools, and explanations of how to use them - when a machine slows down or freezes up, I'd like to be able to dig down and understand what's going on, memory / disk / CPU-wise. Thanks.

  • Windows 7 Task Scheduler Hidden setting doesn't work

    - by Joshua Frank
    I've got a daemon process that I run on my machine every hour, and even though I've checked the Hidden box, it doesn't work. Every hour, the task runs, but it shows the black command window, in which my .NET Console app is running. This stays visible until the task completes, and then disappears. This is very annoying, because it pops up and interrupts whatever I'm doing: I really do want it hidden, so how can I fix this?

  • Sync local directory with remote FTPS?

    - by A T
    How do I keep my local directory in sync with my remote FTPS directory? Note that I've tried WinSCP, but found that it only works a few times then I need to restart it to get it going again. Also I've tried all the utilities mentioned here but only a few supported the connection requirements (explicit SSL over FTP), and those that did didn't have "realtime" directory sync. Also note that a curl, rsync or wput command which I can put into "scheduled tasks" will suffice, if it can do directory sync.

  • Descending list ordered by file modification time

    - by LanceBaynes
    How can I generate a list of files in a directory [for example, "/mnt/hdd/PUB/"] ordered by the files modification time? [in descending order, the oldest modified file is at the lists end] ls -A -lRt would be great: https://pastebin.com/raw.php?i=AzuSVmrJ But if a file is changed in a directory, it lists the full directory, so the pastebined link isn't good [I don't want a list ordered by "directories", I need a "per file" ordered list] OS: OpenWrt [no Perl - not enough space for it :( + no "stat", or "file" command].

  • RHEL json gem installation requires make?

    - by Salahuddin559
    When I try to install json gem (gem install json), at first it fails to do so, because of some dev package issue. After fixing it, it fails saying that "sh: make: command not found" and "ERROR: Error installing json: ERROR: Failed to build gem native extension.". Why is it failing on make? Notice this is not Mac, this is in RHEL 5 (4 or 5, not sure). Why is it not able to do some "build gem native extension"?

  • Run verilog on Mac

    - by Gabe
    I need to simulate verilog on my Macbook Pro for school. I've tried downloading, configuring, and installing icarus and veriwell. The make test works for icarus, but not for veriwell, neither of them are recognized by the terminal. The command I'm using is: iverilog hello.vl and veriwell hello.vl Terminal claims that neither of these commands exist... I'm very new at configuring tools with the terminal, but I think the issue is just USING the program afterwards. Any ideas?

  • ssh during low bandwidth

    - by kfmfe04
    I currently invoke the following ssh command over my home wifi (from OSX to Ubuntu): ssh -XYC -l my_username -c arcfour,blowfish-cbc -XC my_local_server This works great, except during low bandwidth situations, like if I'm streaming music over the Web, while I'm coding. In these situations, the ssh often drops, within a minute or two. Is there a better setting or configuration that I can try over low-bandwidth situations?

  • How to Setup Ubuntu Mail Server with Google Apps?

    - by Apreche
    I have a domain, let's call it foobar.com. All of the MX records for foobar.com point to Google's mail servers because I am using Google Apps for your domain to manage it. It's great because everyone gets all the advantages of GMail, but our e-mail addresses aren't @gmail.com. I also have a server. Primarily, it's a web server, but it also serves other things. One of the things it serves is the web site for foobar.com and also sites for various virtual hosts such as shop.foobar.com and forum.foobar.com. The server is running Ubuntu 8.04, because I like using LTS releases in production. The thing is, there are various applications running on the server that need the ability to send out emails. Various applications, like the cron jobs, send me e-mails in case of errors. Some of the web applications need to send e-mail to users when they forget their passwords, to confirm new registered users, etc. Lastly, it's nice to be able to send e-mail from the command line using the mail command, or mutt. How can I setup the mail on the web server to go through the Google apps mail servers? I don't need the web server to receive mail, though that would be cool. I do need it to be able to send mail as any legitimate address @foobar.com. That way the forum application can send mails with [email protected] in the from field, and the ecommerce application will have [email protected] in the from field. Also, by sending the mail through the Google servers, we can avoid a lot of the problems with the e-mails being blocked by various spam filters on the web. Google's SMTP servers are trusted a lot more than mine would be. I'm pretty good with administering Linux systems, but I am absolutely brain dead when it comes to e-mail. I need step by step directions from beginning to end on how to set this up. I need to know every thing to install, and every single change to the configuration files that is necessary. I have tried following various howtos and guides in the past, but none of them were quite right. Either they didn't work at all, or they offered a configuration that is not what I wanted. Please help. Thanks.

  • Puppet Exec fails executing useradd

    - by chris
    From what I understand, puppetd runs as root. As root, I launch puppetd --onetime --no-daemonize --verbose So I don't understand why this doesn't work: exec { "useradd -m testuser": path => "/bin:/usr/bin", } I just get: ...Exec[useradd -m testuser]/returns: change from notrun to 0 failed:useradd -m testuser returned 1 instead of one of [0] at... If I execute the command directly, it works just fine. Any ideas?

  • batch file infinite loop when parsing file

    - by Bart
    Okay, this should be a really simple task but its proving to be more complicated than I think it should be. I'm clearly doing something wrong, and would like someone else's input. What I would like to do is parse through a file containing paths to directories and set permissions on those directories. An example line of the input file. There are several lines, all formatted the same way, with a different path to a directory. E:\stuff\Things\something else (X)\ (The file in question is generated under Cygwin using find to list all directories with "(X)" in the name. The file is then passed through unix2win to make it windows compatible. I've also tried manually creating the input file from within windows to rule out the file's creation method as the problem.) Here's where I'm stuck... I wrote the following quick and dirty batch file in Windows XP and it worked without any issues at all, but it will not work in server 2k8. Batch file code to run through the file and set permissions: FOR /F "tokens=*" %%A IN (dirlist.txt) DO echo y| cacls "%%A" /T /C /G "Domain Admins":f "Some Group":f "some-security-group":f What this is SUPPOSED to do (and does in XP) is loop through the specified file (dirlist.txt) and run cacls.exe on each directory it pulls from the file. The "echo y|" is in there to automagically confirm when cacls helpfully asks "are you sure?" for every directory in the list. Unfortunately, however, what it DOES is fall into an infinite loop. I've tried surrounding everything after "DO" with quotes, which prevents the endless loop but confuses cacls so it throws an error. Interestingly, I've tried running the code from after "DO" manually (obviously replacing the variable with the full path, copied straight from the file) at a command prompt and it runs as expected. I don't think it's the file or the loop, as adding quotes to the command to be executed prevents the loop from continuing past where it's supposed to... I really have no idea at this point. Any help would be appreciated. I have a feeling it's going to be something increadibly stupid... but I'm pulling my hair out so I thought I'd ask.

  • Mount Windows share on Linux boot

    - by Delameko
    I'm running VirtualBox in Windows. I have Linux 10.04 installed as a VM. Whenever I log in I have to run to following command to mount my shared Windows web dev folder: sudo mount.vboxsf web_apps /mnt/web_apps Where can I put this line (minus the sudo) so that it will run once when Linux boots up? I'm guessing there must be a root .profile or .login script that runs at some point?

  • Evaluate cron expression

    - by Jake A. Smith
    Is there a command line tool that will simply evaluate a cron expression and return a bool response if it is supposed to be running right now? I'm looking for something I can use as a utility in another bash script. Something like so: run_script=$(/tools/evaluate-cron-expression "02 4 * * *") if [ "$run_script" -eq "1" ] # etc etc I know, I know, I could just setup a real cron job, but I'm playing with the idea of wrapping all of my scheduled scripts inside of another script.

  • using tcpdump to display XML API requests without headers or ack packets

    - by Carmageddon
    I need assistance, I am trying to use tcpdump in order to capture API requests and responses between two servers, so far I have the following command: tcpdump -iany -tpnAXs0 host xxx.xxx.xxx.xxx and port 6666 My problem is, that the output is still hard to read, because it sends the Headers, and the ack packets. I would like to remove those and only see the XML bodies. I tried to use grep -v, but apparently this is all one request, so it filters the entire thing... Thanks!

  • What is a good GUI FTP client for Linux with synchronization features?

    - by VoY
    I would like to find an FTP client for linux (preferably GTK, but if it's for KDE and does what I need, then I'm fine with it) with very good synchronization features. What I want to use this for for is synchronization of local websites to their online production versions. I know there are command line tools, which works fine, but I'm looking for a GUI roughly like Total Commander has.
