  • Exposing server uptime a potential security vulnerability?

    - by Edward Mazur
    I run a browser-based game and as part of a page with a bunch of game statistics, I have the server uptime listed. It's currently at 177 days and so someone mentioned to me that I shouldn't do this because a long uptime indicates the kernel is old and therefore missing security updates. This certainly sounds logical, but I searched around and couldn't find any evidence to support it. So I'm just wondering, is this indeed something I should not have exposed?

  • cluster live postgres 8.3 server

    - by bobinabottle
    Our web application is getting more and more traffic, which is making our poor pg8.3 database server have a little trouble keeping up. I've had a look into using pgpool II for clustering the db to relieve a little strain, and I was wondering how this should be done to minimise downtime considering I would be clustering a live database. Has anyone had experience with this or know of any guides to follow? Cheers :)

  • recommendation for good chassis (case) for first time PC builder

    - by studiohack
    I've been thinking about building my own machine for some time now, and whenever I look at the PC case market, it seems like cases are a dime-a-dozen. As a result, I'm wondering what cases Super Users would recommend in the areas of ease of use, cable management, cooling, etc...in other words, an all-around case for a first time PC builder. Thanks!

  • Bad idea to keep htop running?

    - by Michael T. Smith
    I'm now monitoring multiple servers (3) and in the coming weeks that'll increase (towards 5 or 6). I've been keeping three terminal windows open running htop via SSH and I'm now wondering if there are any downsides to having a connection constantly open to production servers?

  • where does https on apache get it's configuration?

    - by Matthew
    So originally my host (mediatemple dv) has two default directories for the roots: 1)httpdocs/ 2)httpsdocs/ In the conf directory I changed the vhosts.conf and httpd.include and others to change from httpdocs to custom folders. Now I installed a new ssl certificate and https://example.com goes to the default page located at httpsdocs. I'm just wondering where configurations for apache are stored for ssl. Ideas?

  • Sync windows live and gmail

    - by vener
    I was wondering how could I sync the emails between two accounts? I know I can forward them to one of the email accounts but that is not how I want it. Both emails account should have the same email from the same person and their status such as read/unread status synced.

  • Replicate From OpenDJ to OpenLDAP?

    - by Joel K
    I am considering retiring some of our older OpenDJ LDAP servers and replacing with OpenLDAP. (seems to be more widely supported) I am wondering if it's possible to replicate directly from OpenDJ to OpenLDAP as an interim solution to remove the OpenDJ slaves and then flip the master over later. Is LDAP replication implementation specific or more general? I guess I'll have to just go give it a try, but I was looking for advice from someone who's been down this road.

  • Command line raw image processing tools in Linux?

    - by ???
    I'm wondering if there is any command to process raw images, for example, cat raw1.img | raw2jpg -w 640 -h 480 -pitch 1024 -pixelformat R8G8B8 and more examples: cat raw1.img raw2.img >y-merge.img tr='transpose -pitch 1024 -depth 24' cat <(cat raw1.img | $tr) <(cat raw2.img | $tr) | transpose -pitch 480 >x-merge.img and something like this: cat gamebitmap.dat | ( w=`readint32` h=`readint32` raw2png -w $w -h $h -depth 24 -pixelformat R8G8B8 ) | png2svg -extractoutline -fuzzy -error 8 -smooth Seems a little tricky, but is it possible? does ImageMagick support such raw formats?

  • Understanding the nop byte(s)

    - by Cole Johnson
    Ok, so I was reading through the AMD64 manuels and knowing that nop is really an xchg eax, eax, I looked at the xchg and found something interesting, that it seems a byte can be encoded into the instruction for specifying the registers (apologies I'm on my iPod): picture. So what I am wondering is how does the processor know if there is a byte after to work with or is it that that extra register has to be of type rAX causing it to actually still be the one byte 0x90

  • Why does localhost and 127.0.0.1 resolve to different locations on Mac OSC 10.8?

    - by Greg Wiley
    I set up a local server without MAMP, for various reasons. I used this tutorial: http://coolestguyplanettech.com/downtown/install-and-configure-apache-mysql-php-and-phpmyadmin-osx-108-mountain-lion I'm just wondering why the local IP and localhost resolve to two different locations. Right now the IP resolves to a Virtual Host I set up and the localhost resolves to the DocumentRoot established by httpd.conf

  • Issues when upgrading OpenSSL?

    - by Zed Said
    We are running an old version of OpenSSL 0.9.7e and would like to upgrade to the most current. Our server is running Debian, and I am wondering if there would be any issues with just upgrading it using apt-get? Would we have to worry about anything breaking, or updating any configurations?

  • How do I fix a corrupted copy of .Net Framework on Windows 7?

    - by David
    I receive the following error when trying to run applications that require .net Framework 3.5: "Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The module was expected to contain an assembly manifest." I've tried numerous fixes, such as reinstalling through ad/remove software, copying the .net folder over from a clean windows 7 install, and running the .net cleanup tool. Just wondering if anyone has run into this issue before, or has an idea on how to fix it.

  • Rack layout tools

    - by Luke
    I'm wondering if there's any tools (preferably offline) that would allow me to layout all of the new equipment that will be going into several standard racks. Currently I'm using Excel to map out all of the slots columns for the data but I suspect that there is some better method of doing this. Suggestions? Edit: Dell has an online tool, but doesn't seem very good at actually saving the data that you're working on (and obviously it's geared towards Dell hardware).

  • Group Policy fault - Students force

    - by Richard 'Bean' Williams
    Work at a school and we've got a scenario. We block F8 on all computers so students cannot access Safe Mode to bypass Group Policy... But students are logging into their accounts using AD, and they are turning them off half way through. Then they are claiming that when they login next time, they have Local Administrator accounts. Is this right, but we have blocked F8 and Startup repair, so wondering how they actually did it. Cheers Richard

  • Compacting solr indexes

    - by womble
    I've got a sizeable Solr server which is chewing a pile of disk. Whilst it is indexing a large amount of data, I'm wondering if there's any operation that will reduce the size of the index, by say dropping deleted-but-still-allocated data in a similar manner to a VACUUM FULL in PostgreSQL, or are the solr indexes kept fairly tidy, and my only option is to just allocate a pile more diskspace?

  • installing a linux iso from within a university network

    - by pepperdreamteam
    In order to install gentoo, I need to connect to a university wireless internet network. It requires a username and password login/authentication. I'm wondering if anyone has any advice in terms of how to configure the internet connection. The Gentoo installation documentation recommends the use of net-setup, pppoe, pptp, dhcp and iwconfig. I can't figure out how to configure this connection, as the only way I understand is to select the network from a list and enter in authentication data from within a browser.

  • Factors affecting network latency

    - by cornjuliox
    I frequently play games like Urban Terror and True Combat Elite, and I was wondering what factors come into play when calculating response time? Is it simply the distance between you and the server? Or does bandwidth fit in here somehow?
