  • where to put core services in two-node cluster

    - by Veniamin
    I'm currently configuring two-node HA cluster based on CentOS with DRBD. Most services are packed in virtual machines with migration available. I have not made decision where to put some core services as: dhcp, ldap, dns - which are critical for all network infrastructure. There are two possibilities: Configure them as redundant HA services on cluster hosts. Pack them all into dedicated virtual machine. What is the best practice?

  • Routing protocols, distance vector vs link state

    - by Artem Barger
    I'm trying to figure out the differences(pros/cons) between two routing protocols approach and I would be great-full for any help, advice and explanation. As far I can say that it seems like distance vector is more static and more local based routing, since it doesn't know the network state whereas link state is more aware of current states therefore it seems more natural to use it over distance-vector, but I have a feeling like I'm missing something. And I would be glad to here about more aspects and different issues I have to consider while choosing one of them.

  • Server Density or Scout-like Services for Windows?

    - by Michael Gorsuch
    Hi all. I've been very impressed with agent-based / SaaS-like monitoring services such as Scout and Server Density. They both provide very nice trending, alerting, and reporting capabilities for my *nix boxes, and I need to find something similar for Windows. Can anyone out there recommend such a tool? It is important that this tool is a centralized service in line with the aforementioned products, as the deployment environment is owned by a lean team with limited resources. Thanks!

  • On demand upload server

    - by stimms
    I'm looking for a simple application which will do something like Allow user to sign up for an ftp account -> ask admin for approval -> create ftp account for that user now it doesn't have to be FTP, in fact I would be happy with a web based tool which supported upload via some sort of java applet or something similar. I don't care about what platform it runs on, although if we could avoid PHP that would be cool. Any ideas?

    - by BSI Support
    I have a half dozen front-end servers all running IIS 6.0-based/hosted applications. (primary .NET 2.0 web apps.) Basically, I'd like to take some basic performance data from each one, through such into a spreadsheet, and compare. CPU load, RAM load, whatever... If anyone can point out a very simple/stupid "here's how you do that" type of tutorial, that would be wonderful.

  • Linux ncurses outliner options

    - by geek
    I'm looking for a replacement for hnb, which served me well but seems to be abandoned. Please do not suggest text-editor based approaches like emacs org mode or vim outliner. I want a stand-alone tool, preferably written in Python, with ncurses interface (so it could run on Linux with no X server).

  • Move data from Interspire Web Publisher to Wordpress

    - by Paul
    We have our helpdesk staff making small articles with Interspire Web Pushlisher, and would like to move that system over to Wordpress. Wordpress seems to be able to import data directly from most blogging platforms directly, but IWP is not one of them. Since they are both PHP-based i figure there has to be an easier way than c-c c-v over and over. Any ideas?

  • How can I use Zend Studio for Java development?

    - by Itay Moav
    I have the Zend Studio, which is a PHP editor based on Eclipse. I want to use it now to develop some Java. I think Zend has disabled all the Java centric project/views/perspectives that come with Eclipse (or may be not included the right plugins?) What steps should I take to use it, instead of having two Eclipse instances open at the same time.

  • Outlook automation

    What do people here use to automate work with outlook? Programming scripts to filter messages instead of using the GUI? A macro to email out notices based on an Excel list with dates? I'm looking for further ideas on automating the paperwork parts of my day.

  • Best filesystem choices for NFS storing VMware disk images

    - by mlambie
    Currently we use an iSCSI SAN as storage for several VMware ESXi servers. I am investigating the use of an NFS target on a Linux server for additional virtual machines. I am also open to the idea of using an alternative operating system (like OpenSolaris) if it will provide significant advantages. What Linux-based filesystem favours very large contiguous files (like VMware's disk images)? Alternatively, how have people found ZFS on OpenSolaris for this kind of workload?

  • 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?

  • Rename/Move file only if destination does not exist

    - by mikeY
    I would like to know if there is any way a file can be moved only if the destination does not exist - in other words, move only if it does not lead to overwriting. mv --update seemed first to be the solution, however, if the timestamp of the source path is newer than the destination, move will overwrite it and all attempts to circumvent this by modifying the timestamp before the move will fail. I need this behaviour to implement a simple file based lock where existence of a 'lock' file indicates that the lock is acquired.

  • How to approach taking a very diverse hybrid network and making something lean and cohesive

    - by Gregg Leventhal
    I am going to have an opportunity (from the role of Linux Sysadmin) to work on optimizing a corporate server network that has a lot of different application servers from LAMP stacks to JBOSS to IIS based ASP/.NET systems of all sorts. I am interested to hear how you would approach evaluating and consolidating a network in a situation like this where you are walking in cold? What are some of your go-to techniques?
