• Remote Access Problems with DRAC 5 on Dell PowerEdge 1950

  - by Darin Peterson

  Today I received my first Dell PowerEdge 1950 server with a DRAC 5 card. On my local network I have static configurations on my Linux systems using this for instance: iface eth0 inet static address 192.168.1.210 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 dns-nameservers 8.8.8.8 8.8.4.4 For the DRAC card, I configured the LAN like this: address 192.168.1.215 netmask 255.255.255.0 gateway 192.168.1.1 For the advanced LAN settings I used dns-nameservers 8.8.8.8 8.8.4.4 I've tried many different IP addresses, but cannot communicate with the card. Is there anyone who might know if I have configuration issues, or maybe if the card might be bad?

• How to define a layered model for Storage Architecture ?

  - by Berkay

  i don't have enough knowledge about storage systems but have to tell my audiences about how storage works in organization data centers. For this purpose to keep things simple, first i want to show them a layer model then from top to bottom and then i want to explore all these layers. What i mean by layered model in storage architecture? i want to start my presentation something like that, first layer can be applications, application request a data from storage and then ... ... (the topics i want to cover are file sytems, metadata,the physical implementation of storage (das, nas etc.) ... the request comes to the storage device and storage device (depends on the technology) goes through the disk and disk send back the data using iscsi protol, we can say that the iscsi protocol managing the path between... ... if you help me explain these steps layer by layer by examples and key technologies to be defined, really appreciate it. thanks.

• Looking for FTP server that allows user management from database

  - by hughesdan

  I'm planning a server application that will handle files uploaded via FTP. The application must parse text documents that it receives and write them to a database (most likely a document-oriented database like Mongo). And the application must also relay all large binary files it receives to Amazon S3 for storage and hosting. I'd like to manage all aspects of the FTP server programmatically. For example, when a user registers via a web page the application should be able to create the user account in the database and provision a directory on the server for receiving files. I'm using a Linux server but am otherwise open to considering any programming language or framework. I experimented with VSFTPD but didn't like the way the application relies on config files and the creation of users and directories via the command line. Can someone please recommend what server framework I should consider? I'm a little biased toward solutions that leverage Javascript/Nodejs or Python. However, I'm open to anything that can run on a Linux box.

• Sar data not collected for 10 minutes

  - by Ichorus

  We have a RedHat server whose only job is to run a JBoss server. Monitors said that memory usage spiked (we have the JVM limited to far less than the total memory on the system) and JBoss crashed. We restarted and everything seems ok now. Odd thing is that sar data for 10 min leading up to the crash is simply not there. Load average got up to the 50s. I have seen severely busy systems (350+ Load Average) still collect sar data. Does anyone have any idea what could cause sar to stop collecting data?

• Google and Yahoo redirect my site to malware, but direct url works fine. Any computer

  - by UserZer0

  I can go directly to the site doublewing.org or www. without issue, but if I click on the link in google or yahoo it redirects to spam sites. Swagbucks works though! This is not on a single computer this happens on systems isolated from each other(Try it, avast blocks it) . The site is runing joomla 1.5.25 . I deleted .htacces, put fresh index.php and index2.php files. and still get the same results. Any ideas?

• Problem with Nobody and PhP

  - by user39190

  We use Cpanel/WHM and have just used EasyApache to upgrade to Apache 2.2 and PhP 5.3.2 As a result of the upgrade process, the user "Nobody" who runs php can no longer access directories or create directories in the various owners web directories. For instance, with Word Press we can no longer upload images. We have tried rebuilding with SuEXEC on and off, SuPHP on and off and nothing makes any difference. It feels as if the user "Nobody" has got its permissions messed up, but that is a wild guess. How can we get back to where we started which is, I assume, that "Nobody" had the rights to the file systems in the web directories?

• Why the huge difference between etch and lenny MySQL

  - by rmarimon

  I've been working on a program for the last year. The development environment is working with a database in MySQL running on debian etch version mysql Ver 14.12 Distrib 5.0.32, for pc-linux-gnu (i486) using readline 5.2. The production environment is working on debian lenny with version mysql Ver 14.12 Distrib 5.0.51a, for debian-linux-gnu (i486) using readline 5.2. I was just timing some database access and what takes in the development environment 150 seconds, takes 300 in the production environment. I checked the /etc/mysql/my.cnf files on both systems and the only differences are # development bind-address = 10.168.1.82 log_bin = /var/log/mysql/mysql-bin.log # production bind-address = 127.0.0.1 myisam-recover = BACKUP #log_bin = /var/log/mysql/mysql-bin.log I dump a database from the production and load it into the development and with the same server everything takes half the time !!! What should I check?

• VMware ESXi - vSphere - Can't exit VM console access

  - by caleban

  I'm running ESXi 4.1 on a Dell T110 Server I connect to ESXi using vSphere vSphere is running inside a Windows 7 VM The Windows 7 VM is running in VMware Fusion on my Mac OS X system When I'm in vSphere and I've selected a VM and I click the console tab on some systems the VM console won't release me when I press the control + command keys. pfSense (FreeBSD) and Ubuntu Server behave like this. I can't exit their console screen. I have to shut down these VM's to be released from their VM console access. Windows, Ubuntu Desktop, etc. all behave like I'd expect; When I press the control + command keys I'm released from the VM console and I'm able to navigate in vSphere. Does anyone know what might be causing this or a way around this? Thanks in advance.

• How much processor speed and cores do I need for these tasks?

  - by ajay

  I am planning to buy a new laptop as I find my current one very slow. My question here is specifically related to RAM size and CPU power. I will mostly be doing development (not much games). I would be dabbling in distributed computing, multithreaded and data intensive parallelizable tasks on multi-cores. For e.g. I would want to be able to Concurrent programming in Scala/Java/Clojure etc. and be able to see parallelization. Furthermore, I would want the RAM to be enough. But from a developer machine standpoint, do you think 4GB RAM and 2.53GHz Dual Core processor would be enough. I'm basically looking at this model: http://store.apple.com/us/configure/MC118LL/A?mco=MTM3NDcyODk (link dead)

• Open Source project that does SSL Inspection

  - by specs

  I've been assigned to research out and spec replacing our old and decrepit http content filtering system. There are several open source filtering packages available but I've not come across one that does SSL inspection. The new system will scale to many branches of different sizes, from say 10 users to a few hundred, so purchasing an appliance for each branch isn't desirable. When we're further along, we will do custom programming as we have a few unique needs in other aspects of filtering, so if the suggestion takes a bit of customization, it won't be a problem.

• HTTP-DAV on IIS 7.0

  - by Ismail

  I wan't to integrate .NET Application Updater Component in my application for auto update of client application. It says The .NET Application Updater component uses HTTP-DAV to download the application update and thus requires a Web server that supports HTTP-DAV. IIS 5.0 that comes with Windows 2000 and newer operating systems support HTTP-DAV. My server is a Windows 2008 Server and runs IIS 7.0. Does IIS 7.0 support "HTTP-DAV"? And if yes how can I enable it?

• Tutuorial for Quick Look Generator for Mac

  - by vgm64

  I've checked out Apple's Quick Look Programming Guide: Introduction to Quick Look page in the Mac Dev Center, but as a more of a science programmer rather than an Apple programmer, it is a little over my head (but I could get through it in a weekend if I bash my head against it long enough). Does anyone know of a good basic Quick Look Generators tutorial that is simple enough for someone with only very modest experience with Xcode? For those that are curious, I have a filetype called .evt that has an xml header and then binary info after the header. I'm trying to write a generator to display the xml header. There's no application bundle that it belongs to. Thanks!

• Authenticating Linux users against AD without Likewise Open

  - by Graeme Donaldson

  Has anyone got their Linux systems authenticating against Active Directory without using Likewise Open? We are close to implementing Likewise Open, but first we need to rename roughly 70 of 110 Linux servers so that their hostnames are not longer than 15 characters. This is required because Likewise Open actually joins the Linux computer to the domain, and it fails to do so if the hostname is too long due to some legacy NetBIOS naming limitation. Is there a way to authenticate via AD, using only LDAP perhaps? What are the advantages/disadvantages over doing it like that vs just using Likewise?

• Why does Windows Update download updates for 32-bit Win 7 when I have 64-bit and how to solve it?

  - by verve

  I have my Windows Update set to "I'll choose when to install" instead of updates installing automatically; good thing too because 90% of the updates are for 32-bit systems! Am I suppose to install them? Shouldn't I only install 64-bit version updates? And, how to I make Windows Update download the proper updates only? Side question: Is there a way to "unselect all" in the Windows Update app? Win 7 64-bit. IE 8.

  - by SBWorks

  In a situation where you are running: VMware Infrastructure 4.x with multiple hosts Over 150 VMs with a wide variety of operating systems (Linux in a half dozen distros, Solaris, every MS version, etc.) in multiple languages with almost every mix of installed software (luckily, no Exchange mail servers) Using an EMC fiber channel SAN The VWs that need need to be backed up use about 2 terabytes of data (total) The goal is to keep backups for about 3-months At this rough scale, what backup solutions have worked well for you? And, as an add-on question, did any of them have de-duplication that you thought was effective and useful?

• Mysterious problem...can remotely connect to a system but can't browse back out.

  - by GregH

  I have LogMeIn installed on my home system. I went on travel and my wife called saying that none of our home systems could browse the internet. I thought I would try to connect to my home system using logmein. Surprisingly, I was able to connect to my home system and log in without any problems using logmein. When I opened a browser from my home system, I indeed could not browse. I opened a command prompt and tried to ping my router (192.168.1.1) and it failed/timed out. How is this possible? I can remotely connect to my system but once logged in cannot even ping my router. What's up with that?

• Domain connection shows as "unauthenticated"

  - by gareth89

  I have seen various different questions for this problem floating around but either the circumstances arent the same or the solution doesnt work so thought i would post it to see if anybody has any suggestions. Various domain PCs and laptops appear to randomly give the connection name of "lewis.local 2(Unauthenticated)" - lewis.local being our domain - and provides an exclamation mark where the network type logo is normally shown. This also appears to happen every time connecting via vpn. Our setup is: 2 servers both running windows server 2003 R2 (x32) main server has AD, DNS and DHCP installed IPv4 on approx 30 client machines (some wired, some wireless) If anybody has any thoughts on solutions i would appreciate it. I have tried removing all but AD server roles, resetting all of the systems and nothing. It doesnt prevent anything from working just like a domain connection most of the time however it is getting fustrating! Also dont know if it could have anything to do with it but the DHCP server seems to have quite a long lead time on issuing the IP address to the client.

• Satellite TV on my PC?

  - by jasondavis

  What would be a good solution for hooking up the satellite TV box (Dish network) in my room to be able to watch it on my PC and possibly record video from it? Please share with me the best cards, cables, software, anything else needed to do this in the most efficient way? I am looking at the WinTV-HVR from Hauppauge. I am not sure, for performance, what would be the best to go with, PCI, PCI express, USB2.0? Also on the Hauppauge website I saw this note: "WinTV-PVR products will not work in PC systems with 4GB or more of memory." The new PC I am building will be 12-24gb of DDR3 RAM, does that mean their products will not work at all with my memory? So confused now!

• Run application or script on Windows RDC connection

  - by NickLarsen

  I checked this thread, but it did not solve my exact problem. I need to run a script on when a connection is made across my network using windows remote desktop connection. The thread listed above works for the initial login, however, if I don't log out (which is necessary for some processes running on my network), then it wont run the script again the next time someone connects to the system using remote desktop connection. Previously we were using pcAnywhere to achieve this, however after running into some graphical issues with pcAnywhere, we have decided to move away from it to RDC. For a little more information, we need to have an email sent out anytime a connection is made to particular machines. The login name will always be the same for those systems and we do not log off when closing the connection.

• Location of truetype fonts

  - by StackedCrooked

  I would like to create a small script that installs a few truetype fonts on the user's system. On my Ubuntu machine the truetype fonts are located at /usr/share/fonts/truetype. However, I'm not sure if this location is the same on all machines. Is there a way to find out where truetypes fonts are stored on any Linux system? Update After some research I found that the path usr/share/fonts/truetype is specified in the XML file /etc/fonts/fonts.conf. It's an XML file, so I can use XPath to get the dir: xpath -q -e 'fontconfig/dir[1]/text()[1]' /etc/fonts/fonts.conf I don't know however if this file will exist on all (or most) Linux systems.

• Configuring Notepad++ to run knitr2pdf

  - by Stat-R

  Sorry for such a basic question but since I do not have a degree in programming... I am a user of R, knitr and Notepad++. I was trying to configure Notepad++ to run pdflatex and knitr(knit2pdf). By googling I found how to do it for pdflatex but I did not find anything for sweave/knitr. The following are the good ones for pdflatex http://www2.sofi.su.se/~mbe/docs/npp_r_latex.pdf http://www.tlhiv.org/ma497/software/ I inserted cmd /c cd /d "$(CURRENT_DIRECTORY)" && pdflatex.exe -shell-escape "$(FILE_NAME)" into the runrun menu in Notepad++. I do not fully understand the command though. I will appreciate any help on this. Please direct me if you can to any resource for learning these commands. I will be grateful to get any help in configuring Notepad++ for running knitr.

• Virtualmin Configuration

  - by Allen

  I am trying to get Virtualmin setup and have reached a point where my noobish sysadmin skills aren't getting the job done. This is the message I get now when I try and refresh the configuration of Virtualmin. BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server XXXXXX is not a fully qualified domain name. Sendmail is only accepting SMTP connections on the following ports : 127.0.0.1 port smtp. Email from other systems on the Internet will not be accepted. This can be changed in the Sendmail Mail Server module. Please advise what I need to do to get Sendmail configured properly. Thanks!

• How do I mount a harddrive to my /home folder in OS X?

  - by Joachim Hedberg

  Im wondering how to mount my second HDD to my /home folder like you do in other *NIX systems, making the mount point just that folder and not a standard HDD. I am aware of the method of copying my /home folder and then telling OSX via System Preferences/Users & Groups to look for the folder in a different location. What I am wondering is if there is a way to properly mount the entire HDD to become nothing more than my /home. I don't want it to even show up in Finder as an HDD. Is this even possible?

• Process for configuring network settings on a headless rack mount device

  - by PherricOxide

  I'm with a small company that plans to sell a rack mounted network appliance which is configurable via a web interface (think of a router configuration page sort of deal), and I'm wondering in large data center like environments what the process usually is for the initial setup of such systems. The main question is, if the system is headless, how do you get initial remote access to it? Do companies usually first plug a server into a monitor/keyboard/mouse in order to configure the network settings before mounting it in a rack? How else would they know what the IP address of the machine was if DHCP (and it can't be hard coded because of IP conflict potential)?
