  • Route return traffic to correct gateway depending on service

    - by Marnix van Valen
    On my office network I have two internet connections and one CentOS server running a website (HTTPS on port 443). The website should be publicly accessible through the public IP of the first internet connection (ISP-1). The other internet connection, ISP-2, id the default gateway on the network. Both internet connections have routers (the household-kind) with NAT, SPI firewalls etc. The router on ISP-2 is a Netgear WNDR3700 (aka N600) with original firmware. The problem is that the website is unreachable. Looks like incoming traffic on ISP-1 will reach the server but the returning traffic is routed through ISP-2, effectively making the site unreachable. As far as I can tell I can't do port based routing on the WNDR3700. What are my options to make this work? I've been looking at implementing an iptables / routing based solution on the server itself but haven't been able to make that work. Update: Note that the server has one network interface connecting it to both routers.

  • USB seems to pause system

    - by Marco van de Voort
    I've an application that does some simple measuring, for which it polls a few 100kbs several times a second (8-25 times) The behaviour is not really dependant on chipset (happens on several mobo's intel 965- P55) and OSes (XPsp3 and win7). Also the make of the USB keyboard doesn't seem to matter. I notice that sometimes when an USB kbd is plugged in, the system pauses for say 500-1000ms. (about 900-1000ms on disconnect, and 400-500 on the subsequent connect) It also happens for other USB devices (most notably mice and massstorage devices), but only the first time such device is connected to an installation. This disrupts the measurement and I really would like to get rid on this. I already tried to disable as much as possible. (powersave, teletubby mode (*) etc), and while this helped with the non-USB related disruptions of the measurement, it doesn't help with the USB related ones. (*) fyi, turning off themes (to resp. classic/non-aero), and turning off effects in system solved problems that occured when minimizing/maximizing the app. Any pointers to look into? I'm a bit stuck with this.

  • Tar dereference only 1 level

    - by Bart van Heukelom
    I use the following pseudo-script to create a TAR of my installed software mkdir tmp ln -s /path/to/app1/bin tmp/app1 ln -s /and/path/going/to/the-app-2 tmp/app2 tar -c --dereference -f apps.tar tmp I need the --dereference option here to follow the links I just made in tmp. The reason I make the links in the first place is to store the directories with a different name in the archive than they have on the filesystem. Until now it has worked fine. However, I now have the situation that /path/to/app1 also contains links, and those I don't want to follow. Is this possible with some changes to the tar command? Or do I need to completely switch around the way I build the archive?

  • Two SSL certs for a domain in DirectAdmin

    - by Bart van Heukelom
    If I were to get 2 SSL certificates, one for example.com and one for www.example.com, is there a way to install them both on the site example.com in DirectAdmin? The default interface only allows installing one for both versions. If not, can I separate the 2 domains into 2 sites? One of them would only be a redirection, so there wouldn't be any duplication of site files. (Please don't answer with "one certificate should work for both". It doesn't always. This is a DirectAdmin question)

  • VNC unattended Server (No user Interaction)

    - by Louis van Tonder
    I worked on a proof on concept a while ago.... whereby I managed to get VNC going in full "unattended" mode... I.e. The VNC Server dials into the viewer... which is running in Listening mode. The same concept of how single click works, but without the user interaction. I cant seem to locate my source files for this concept I worked on... although I have found my shortcut that worked on the Viewer side to listen. "C:\Program Files\UltraVNC\vncviewer.exe" -listen 5007 /noauto /256colors I can not however remember/locate my demo of what the server is doing.... how to configure it. If I remember correctly, the server was also started with command line params that "dialed" into a remote IP/port, that the viewer is listening on. Any ideas? Thanks

  • sbs-server with 2 nics and 2 connections to the internet with different providers not working as it

    - by erik-van-gorp
    We have the following configuration : A sbs-2003 server in a domain (mydomain.com) with 2 network cards, each connected to a different network (provider), with different gateways, one for web and one for mail and clients. (we do this because the bandwitdh we get from our providers is too small to handle all the mail(+spam) traffic and webservices, so we took 2 providers) DNS is as follows : www.mydomain.com 1.2.3.4 mail.mydomain.com 5.6.7.8 NIC 1(192.168.1.3) is connected to to the internet through a firewall at 192.168.1.1, having wan address 1.2.3.4 NIC 2(10.0.0.3) is connected to to the internet through a firewall at 10.0.0.1, having wan address 5.6.7.8 Both nics have their default gateway installed at their corresponding routers. Also the metrics are set equal. (i know this isn't a supported config, but it works more or less). In this configuration i can use RDP on both wan adresses, and telnet to port 25 works as well on both. The issue now is that since a few weeks , we get regular disconnections, and website hickups(timeouts), several per hour. If we set one router to a higher metric, that route no longer works. In short, I want the mails to route through NIC2 and the web through NIC1. Any better configuration (without installing a second mail server) ?

  • Adobe software does not save to network share

    - by Bart van Heukelom
    I'm running Windows 7 inside virtualbox on a linux host. I have shared my linux filesystem so it's accesible in Windows under \vboxsvr\sharename. I've mounted this share on S:. For most software, it works fine. Adobe software like Photoshop has problems with it though. I can read from S: just fine, but if I try to save something it gives me the message "There are no more files". How can I make it able to write to the share?

  • Force ID of user created by apt-get

    - by Bart van Heukelom
    Context: I'm automatically installing postgresql-9.1 on an Ubuntu server with apt-get. This creates the required postgres user. The Postgres data is on an external volume that survives reinstalls. This data is obviously owned by the postgres user. The problem I'm having is that the ownership is not recorded under the name postgres, but under the UID that postgres had at creation time. When the server is reinstalled, postgres sometimes gets a different UID, and no longer owns the data directory, and thus does not work. Question: Can I force the UID of the user postgres created by apt-get to something fixed? Or is there another way to solve my problem? (As you may have deduced, this is on Amazon EC2 with the data on an EBS volume)

  • How can I get Windows to apply its settings?

    - by Jouke van der Maas
    I have a computer with a major problem; it gives a blue screen when the login screen loads. I've been using this guide to troubleshoot the issue, and now I've run into a problem. I have determined the issue is not bad memory or a bad hard drive. According to the guide, this means the problem is in the OS. I've tried to follow the steps, but Windows (Vista SP1) somehow doesn't remember any changes. On every reboot, the computer is in exactly the same state it was in before. Any changes to system settings or files won't be recorded. As this means I can't check what is causing the problem, I can't fix my PC. Is there a way to find out what's causing this? Is it just a mode Windows goes into to protect itself, or is it some other problem? Anything to help troubleshoot will be of great help here. PS. I'm kind of new to this site. If I messed up, please tell me in the comments.

  • Determine from where is "sh" being run under apache www-data user using using PF or NETSTAT

    - by Eugene van der Merwe
    I am working with a compromised Ubuntu 8.04 Plesk 9.5.4 server. It seems that a script on the server is continuously doing reverse lookups to random IPs on the Internet. I first spotted it during by using top and then noticed flashes of this coming up continuously: sh -c host -W 1 '198.204.241.10' I wrote a this script to interrogate ps every 1 second to see how frequently this script happens: #!/bin/bash while : do ps -ef | egrep -i "sh -c host" sleep 1 done The results are that this script runs often, every few seconds: www-data 17762 8332 1 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 17772 8332 1 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 17879 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 17879 17869 1 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 17879 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' root 18031 17756 0 10:07 pts/2 00:00:00 egrep -i sh -c host www-data 18078 16704 0 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 18125 17996 0 10:07 ? 00:00:00 sh -c host -W 1 '91.124.51.65' root 18131 17756 0 10:07 pts/2 00:00:00 egrep -i sh -c host www-data 18137 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 18137 17869 1 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' My theory is if I can see who is launching the sh process or form where it's launched I can isolate the problem further. Can somebody please guide me using netstat or ps to identify from where sh is being run? I might get many suggestions that the OS is out of date and so the Plesk, but please bear in mind there are some very concrete reasons why this server is running legacy software. My question is aimed at a advanced Linux systems administrators who have in depth experience with security compromises and using netstat and ps to get to the bottom of it.

  • Clean out a large MediaWiki text table

    - by Bart van Heukelom
    I just discovered that an old MediaWiki of mine was infested with spam, and the database table named "text" (which contains the page content) is 3GB large. I've deleted all the spam pages manually, but: The table is still the same size. I wonder how it got to 3GB anyway. There wasn't that much spam (about a hundred medium-sized pages) How can I get rid of this mess? If you want to inspect the wiki, it's over here. The database is MySQL 5.0.75.

  • Wordpress on Apache is redirecting all https to http

    - by Krist van Besien
    I have a problem with a wordpress site on a server I admin. I don't know anything about wordpress however. My problem is that we want the site to be accessed over https, bot somehow all requests to https:// URLs are answered by the server with a 302, redirecting to http. The wordpress site itself is configured to use https, and we see that in the pages that are generated the links are all https links. In the apache config there are no rewrite rules and no redirects. However, any request to a https:// URL is answered with a redirect to the equivalent http URL. And I really would like to know where these redirects are coming from, what is generating these redirects. I've increased the loglevel on the webserver to DEBUG, but did not get any info there. I tried to enable debug logging in wordpress per the recipy I found here: http://codex.wordpress.org/Debugging_in_WordPress But did not get a debug.log file in the directory where one should appear. I'm really at a loss here, and need to fix this urgently. Any hints as where to start looking? Apache is 2.2.14 on Ubuntu. There are several other virtual hosts on this server, using php and https without any problem... Edit: I created a small info.php script and dropped that in the webservers' root. Calling this yields the output of the script, no redirect is generated. This suggest that it's not the webserver, but wordpress that is doing it. A second thing I noticed is that the redirect comes with several cookies, one of which has "httponly" set. Could that be it?

  • Podcast Show Notes: Evolving Enterprise Architecture

    - by Bob Rhubart
    The latest series of ArchBeat podcast programs grew out of another virtual meet-up, held on March 11. As with previous meet-ups, I sent out a general invitation to the roster of previous ArchBeat panelists to join me on Skype to talk about whatever topic comes up. For this event, Oracle ACE Directors Mike van Alst and Jordan Braunstein  showed up, along with Oracle product manager Jeff Davies.  The result was an impressive and wide-ranging discussion on the evolution of Enterprise Architecture, the role of technology in EA, the impact of social computing, and challenge of having three generations of IT people at work in the enterprise – each with different perspectives on technology. Mike, Jordan, and Jeff talked for more than an hour, and the conversation was so good that slicing and dicing it to meet the time constraints for these podcasts has been a challenge. The first two segments of the conversation are now available. Listen to Part 1 Listen to Part 2 Part 3 will go live next week, and an unprecedented fourth segment will follow. These guys have strong opinions, and while there is common ground, they don’t always agree. But isn’t that what a community is all about? I suspect that you’ll have questions and comments after listening, so I encourage you to reach out to Mike, Jordan, and Jeff  via the following links: Mike van Alst Blog | Twitter | LinkedIn | Business |Oracle Mix | Oracle ACE Profile Jordan Braunstein Blog | Twitter | LinkedIn | Business | Oracle Mix | Oracle ACE Profile Jeff Davies Homepage | Blog | LinkedIn | Oracle Mix (Also check out Jeff’s book: The Definitive Guide to SOA: Oracle Service Bus)   Coming Soon ArchBeat’s microphones were there for the panel discussions at the recent Oracle Technology Network Architect Days in Dallas and Anaheim. Excerpts from those conversations will be available soon.

  • Agile PLM on Developing Agile PLM: Software Lifecycle Management

    - by Kerrie Foy
    Change is constant.  That saying couldn’t be truer when applied to software development.   And with all that change comes extensive product complexity.  How do you manage it all?  As software developers ourselves, we can certainly empathize with the challenge. On April 3, 2012 Stephen Van Lare, VP of PLM Product Development, hosted a webcast to share how Oracle uses Agile to develop Agile – a PLM solution for managing a PLM solution!   Stephen passionately shared his unique insight based on 10 years of using Agile PLM to manage the development process, as well as customer use cases.  He shared our time-proven view of the software’s relationship to the product record, while pointing out that PLM is not source control.  He began with the challenges of software development, which boiled down to the deduction that “despite many great tools in the software development industry, it takes a lot more than good source control, more than good bug tracking, to get to an on-time, on-budget and quality release in your marketplace.   It requires defining the right things you want to do, managing the scope, managing your schedule, and, most importantly, managing the change to all those things over the lifecycle of the process. And this is the definition of PLM.”   Stephen then defined the relationship of PLM to the software development process by detailing the two main use cases –  Product Lifecycle and Mechatronics – which can be used simultaneously and in fact are already used in most industries today.  The Product Lifecycle use case is used to manage artifacts and change throughout product development, while the Mechatronics use case involves the software, hardware and electrical design in the BOM.  In essence, PLM is just as relevant to software as the rest of the BOM when trying to maximize profits during any phase of the lifecycle. Please take the opportunity to watch Stephen Van Lare as he details how and why based on his own experience developing Agile with Agile, as well as a lively Q&A session, in the Software PLM Webcast Replay.

  • Dutch ACEs SOA Partner Community Award Celebration

    - by JuergenKress
    When you win you need to celebrate. This was the line of thinking when I found out that I was part of a group that won the Oracle SOA Community Country Award. Well – thinking about a party is one thing, preparing it and finally having the small party is something completely different. It starts with finding a date that would be suitable for the majority of invited people. As you can imagine the SOA ACEs and ACE Directors have a busy life, that takes them places. Alongside that they are engaged with customers who want to squeeze every bit of knowledge out of them. So everybody is pretty busy (that’s what makes you an ACE). After some deliberation (and checks of international Oracle events, Trip-it, blogs and tweets) a date was chosen. Meeting on a Friday evening for some drinks is probably not a Dutch-only activity. But as some of the ACEs are self-employed they miss the companies around them to organize such events. Come the day a turn-out of almost 50% was great – although I expected some more folks . This was mainly due to some illness and work overload. Luckily the mini-party got going, (alcoholic) beverages were consumed, food was appreciated, a decent picture was made (see below) and all had a good chat and hopefully a good time. (Above from left to right: Eric Elzinga, Andreas Chatziantoniou, Mike van Aalst, Edwin Biemond) All in all a nice evening and certainly a "meeting" which can be repeated.  For the full article please visit Andreas's blog Want to organize a local SOA & BPM community?
