  • Functional implications of differences in SSL and TLS

    - by Randell
    I know that TLS is essentially a newer version of SSL, and that it generally supports transitioning a connection from unsecured to secured (commonly through a STARTTLS command). What I don't understand is why TLS is important to an IT Professional, and why given the choice I would pick one over the other. Is TLS really just a newer version, and if so is it a compatible protocol? As an IT Professional: When do I use which? When do I not use which?

    My Wordpress tables appear to be in need of optimization so I looked into the commmand OPTIMIZE TABLE .

Is this normal? How can I optimize my database to keep things working correctly?

  • Remote Control Adapter for PC

    - by Kairan
    Does there exist a product out there that attaches to your PC (preferably USB) that enables Infrared signals to be received (by a regular remote control) ? It seems a novel idea to be able to get a programmable remote that can be used to manipulate windows (like the Harmony remote control series) along with some programmable software (preferably Windows supported) to convert any button on a regular remote to some command on the PC. Does this exist? What is it called? This particular instance you are REQUIRED to use the crappy supplied remote, and this is not what I am looking for

  • How to solve "Broken Pipe" error when using awk with head

    - by Jon
    I'm getting broken pipe errors from a command that does something like: ls -tr1 /a/path | awk -F '\n' -vpath=/prepend/path/ '{print path$1}' | head -n 50 Essentially I want to list (with absolute path) the oldest X files in a directory. What seems to happen is that the output is correct (I get 50 file paths output) but that when head has output the 50 files it closes stdin causing awk to throw a broken pipe error as it is still outputting more rows.

  • Core i7 on linux loses its multithreading capability after suspend

    - by rafak
    On my debian-linux system, with a core i7 920 , each time I resume after the command "pm-suspend" (suspend to RAM), mutlithreading capabilities almost disappear. More specifically, two distinct programs can use 2 distinct cores at full rate, but a single program is limited to only one core (for one instance of a multithreaded program as well as multiple instances of a monothreaded program, e.g. "make -j 4" for gcc). So I end up rebooting the system. Any help appreciated!

  • Best way to override 1024 process ulimit

    - by CamelBlues
    On CentOS distros, there is an /etc/security/limits.d/90-noproc.conf that sets a process limit for all users: # Default limit for number of user's processes to prevent # accidental fork bombs. # See rhbz #432903 for reasoning. * soft nproc 1024 I'd like to keep this limit in there, but allow one user to have more than 1024 processes. Because of how the server is puppetized, I'm unable to use the built-in bash ulimit command.

  • How do I do an exact whois search?

    - by brianegge
    When I execute the following whois command on my Ubuntu server, I get all sorts of other domains which contain google.com in the name, but clearly aren't owned by google. As this appears to be some sort of spam, I won't paste the output here. I'd like to check for exactly the name I typed in. I thought the following would work, but it doesn't. What is the proper way to do an exact match? whois -Hx google.com

  • Why does PSEXEC work if I don't specify a password?

    - by Kev
    When I run PSEXEC to launch a process on a remote machine, if I specify the password in the command line it fails with: PsExec could not start cmd.exe on web1928: Logon failure: unknown user name or bad password. psexec \\web1928 -u remoteexec -p mypassword "cmd.exe" If I just specify: psexec \\web1928 -u remoteexec "cmd.exe" and type in the password it works just fine. The originating server is Windows 2003 and the remote server is Windows 2008 SP2.

  • Cannot Install JDK

    - by Vince
    For the life of me, I can't install the JDK on Windows Vista. I keep getting the error, "This Software Has Already Been Installed on Your Computer. Would you like to reinstall it?" Problem is, it's evidently not on my computer, since I can't a) run Eclipse - I get "Could Not Find Java SE Runtime Environment" or b) Find any reference to Java from the command line when typing java -version - I get "Error opening registry key 'Registry/JavaSoft/Java Runtime Environment." Any ideas?

  • I just restarted Apache and now the server is down

    - by James
    I am pretty terrified right now. I'm scared I'm going to get a call in a couple minutes from a hundred people saying the website doesn't work. I was at the terminal changing some configuration files when I went to restart the server to update the .conf files with this command: /etc/init.d/apache2 graceful After I ran that, none of the websites work and I have no idea what to do. There are about 100 errors I am getting according to the log files. They all begin with "PHP Notice" and most relate to "use of undefined constant" Also, I just spoke with a coworker, describing what I did, and he noticed that there are two installations of apache on the server and that I restarted the one that we don't use. This is what the error log says (assuming it's the correct error log): [Wed Jan 05 11:52:06 2011] [notice] Graceful restart requested, doing restart Warning: DocumentRoot [/u/apps/staging/antetr/current/public/] does not exist [Wed Jan 05 11:52:08 2011] [warn] NameVirtualHost *:80 has no VirtualHosts (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs (2)No such file or directory: apache2: could not open error log file /u/apps/production/madfilmdash/current/log/apache-error.log.

Unable to open logs (2)No such file or directory: apache2: could not open error log file /u/apps/production/madfilmdash/current/log/apache-error.log. Unable to open logs FINAL UPDATE: Ok, I fixed it. The problem was (as you experts facepalming probably know) that it couldn't access an error log in the directory I was working in. I created an empty error log file and tried the restart command again and now all the sites are back up... Though my original problem is still there.. Thanks to all those who offered advice, it really helped and let me breathe for a moment.

    I can't use the ia64-version of devcon.exe on my Windows7 professional x64 (AMD CPU). error message tells me, that the version of this applcation is not suitable for this version of windows and I should check whether I need to use a x64 or x86 version of this application. The x86 version starts correctly, but all operations (remove, restart, disable etc) fail. Running from a command line with full privileges. Any ideas how to solve this?
