• thought on real time web analytics

  - by Linus

  we have a few web servers and am planning to create a dashboard to show the real time stats ip address,geo-location and other custom data based on database lookups. Splunk sort of fits perfectly but wondering if there are any open source alternative . i have looked at logstash and graylog2, but to my knowledge they are more of a log analysis tools. Piwik is sort of interesting except that i cannot put any javascript on the webpages. All i have access to is apache web log. Any recommendations please..

• IIS site hacked with ww.robint.us malware

  - by sucuri

  A bunch of IIS sites got hacked with a javascript malware pointing to ww.robint.us/u.js. Google cache says more than 1,000,000 different pages got affected: http://www.google.com/#hl=en&source=hp&q=http%3A%2F%2Fww.robint.us%2Fu.js http://blog.sucuri.net/2010/06/mass-infection-of-iisasp-sites-robint-us.html My question is: Did anyone here got hacked with that and still have any logs (or network dump) available for analysis? If you do, have you spotted anything interesting in there? Sites as big as wsj.com got hacked and some people are saying that maybe a zero-day on IIS/ASP.net is in the wild...

• *nix OS that is easy to update to latest software

  - by rjstelling

  I need to configure a server (*nix) that runs our (bespoke) CMS and Applications. In the past I have defaulted to using Cent OS 5, but I find this outdated difficult to upgrade the software to the versions we require. For example, we need PHP 5.3, but CentOS 5 has 5.2. Updating is fine but breaks something else (normally MySQL support in PHP). Eventually it will get to a situation where I can't upgrade because of missing dependancies and incompatible versions. Error: Missing Dependency: httpd = 2.2.3-43.el5.centos.3 is needed by package httpd-devel-2.2.3-43.el5.centos.3.i386 (updates) Is there a better alternative OS for hassle free updates, I need: Apache 2.2.17 (the development version for apxs) MySQL 5.5.8 PHP 5.3.5

• Windows service running as network service - how does it authenticate? Breaking change in W2K8?

  - by Max

  A Windows service running as "Network Service" talks to services on other machines (here: SQL Server and Analysis Services), using Windows authentication. For authentication, we have to grant permissions to the machine account of the service. E.g. if service runs on server MYSERVER in domain MYDOMAIN, it'll authenticate itself as "MYDOMAIN\MYSERVER$". - Am I correct, so far? Now here's my question: does this still apply when talking to a service on the SAME machine? Or will it authenticate with something like "NT AUTHORITY\Network Service" instead when connecting to a local service? And: is there any chance this is a breaking change from Windows 2003 to Windows 2008? We're having an actual issue in our system where the account was able to connect to local services with only the machine account having permissions in W2K3. In W2K8, this doesn't seem to work anymore: authentication to local services now fails, but still works to remote machines.

• Can I set up a 2nd home wireless router, with router2 connecting to the internet through a desktop which is wirelessly connected to router1?

  - by gil b.

  Hi, I apologize for the crudeness of my MSPaint drawing, but please view my diagram of what I'd like to accomplish: Proposed home network architecture Currently, all devices are connected to 1 wireless router. I would like to make my own subnet, with a box in-between my subnet and the shared wireless router, so that I can learn about IDS, traffic analysis, etc. I was also given a cisco PIX firewall to play around with, and it'd be an added bonus if I could incorporate that into my network. The reason for this proposed architecture is so that I can monitor all MY traffic, without seeing anything going on with my roommates' traffic. my MAIN Question is, is it possible to have my desktop connect to the wireless router with internet via wireless card AND share that connection via the ethernet card, hooked to wireless router 2? cable modem - wireless router - desktop pc connected wirelessly - wireless router 2 getting internet from wired connection to desktop pc - laptops connected wirelessly The PIX can be left out for now, but I'm wondering if it could eventually be incorporated? THANKS!

• In Enterprise Architect I modified an interface, how to update the realizing classes?

  - by Timo

  I've created an interface in a class model. This interface has two methods, A and B and method A takes an argument (a) and method B does not take an argument (yet). Additionally I've created a class that implements this interface, overriding both methods. After a discussing the model method B now should also take a parameter (b), so I modified the interface to reflect this change. However the class realizing this interface is not updated automatically. For one class it's possible to add the method by re-creating the link between the interface, specify the which method should be implemented and deleting this link again. Then the OLD method signature has to be removed as well. This is a lot of work if there is more then one class implementing the modified interface, not to mention error-prone. Does anybody know how to make an entire class model update this type of dependency?

• SQL Server cluster performance baseline

  - by Dwight T

  Currently I'm tasked with getting a good performance baseline on a SQL 2005 cluster. The main db on the server is for Sharepoint, but I would like to add other dbs on the cluster. I do have access to Quest's Performance Analysis tool to help. What are key factors to look at to see if the cluster can handle additional dbs? Do you look at different performance indicators for a cluster vs a stand alone sql server? One db will be a low usage transactional db and a read only db that is used for sales data. Thanks Dwight

• Installing Apache to CentOs 5.7 (problems with repo)

• How do I install hiphop-php in CentOS 6?

  - by Dai

  I've been trying to install hiphop-php on CentOS 6 with no luck. I found an .rpm for it but it fails dependency checks on boost which fails to install because it depends on curl which fails to install because it can't overwrite /etc/lib64/libcurl.so.4 I can't remove the current curl version because half the system seems to depend on it. Has anybody had any luck doing this? It's driving me mad. I tried compiling from source but that's even more hellish and I really have no idea what I'm doing anyway.

• need recommendation for running PHP/Zend based optimizer

  - by senorsmile

  Firstly, I must admit that I don't know much about setting up PHP beyond the basics. I have an Ubuntu 10.04 server system (hosted) running primarily as an FTP store for a commercial store software. The server that the commercial store is installed on is unfortunately not very reliable, and would like to move that to this Ubuntu 10.04 server. (We've already received permission from the store vendor to do this.) My problem is that they use Zend optimizer which is only compatible with PHP 5.2. I have tried a couple of "hacks" to downgrade PHP to 5.2, but it breaks so many other things that it doesn't seem worth it. My idea is to install some sort of container of Ubuntu 8.04 (like OpenVZ) on the server to house a native install of PHP 5.2 to meet the dependency of the store software. However, it appears that OpenVZ is no longer supported on Ubuntu. Is there another solution similar that I could run on a hosted server to installed a separate "container-like" 8.04 system?

• How can I scrape specific data from a website

  - by Stoney

  I'm trying to scrape data from a website for research. The urls are nicely organized in an example.com/x format, with x as an ascending number and all of the pages are structured in the same way. I just need to grab certain headings and a few numbers which are always in the same locations. I'll then need to get this data into structured form for analysis in Excel. I have used wget before to download pages, but I can't figure out how to grab specific lines of text. Excel has a feature to grab data from the web (Data-From Web) but from what I can see it only allows me to download tables. Unfortunately, the data I need is not in tables.

• curl installation and upgrade

  - by user26202

  On a centos 5.7 machine we had curl 7.15 installed . We also have PHP installed in it as some of the PHP libraries are linked to curl. We wanted to upgrade curl to 7.19 but yum update was failing . Then we manually installed 7.19 with the sources. Now we have two curl versions /usr/bin/curl points to 7.15 /usr/local/bin/curl points to 7.19 And PHP still uses curl 7.15 .How to do delete curl 7.15 without removing the dependency (like PHP and make PHP start using curl 7.19?

• installing and running google-chrome on an old Ubuntu 7.10 legacy system

  - by 12632

  I am trying to get google-chrome to work on Ubuntu 7.10. I installed it with --force-depends and got it to install, but now when I try to run it, I get this error: /usr/bin/google-chrome: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory Is there a way to still get google-chrome to load even without this dependency satisfied? This is an old system that needs to keep this old 7.10 Ubuntu version and I would like to have google-chrome if possible installed, even if it means no sound or other features that are not compatible.

• Network email alerts

  - by stephenfalken

  I would like to buy or d/l an application that will alert our sysadmin in the event of network failure, like via email and/or phone call. I've looked around the net before posting this question, but I have one main concern: if our network goes down, how can a network monitoring application send email to alert us that it's down? Doesn't this have to be an external application that looks at our network from outside? Well anyway, I want to find something that will handle this for us - freeware if possible, sice we're not looking for heavy analysis - just simple alerts. Advice is appreciated.

• Fill a table from a RAND based formula in Excel 2010

  - by Greg Reynolds

  I am trying to do a Monte Carlo simulation using Excel, but a lot of the tutorials I have found are either for older versions of the product, or are not quite what I am after. A simple example of the kind of think I am after is: Cell A1 contains the formula to simulate (for example int(6*rand())+1 to simulate rolling a dice). I have 10 rows of "Trials". What I want is to somehow point each row at a different calculation of the formula in A1. So I would end up with something like Trial Value 1 2 2 5 3 6 4 2 5 1 6 3 7 2 8 4 9 2 10 1 I have tried playing with some of the "What-if Analysis" tools, but I am a bit lost.

• Best Guest OS for running freeswitch under Proxmox

  - by Frank Waller

  We have a lot of asterisk Systems running on dedicated machines and would like to use freeswitch to replace a number of them. One of the advantages of freeswitch is supposed to be that it is doing much better in a virtualized environment than asterisk is. However I can find very little information about people using it in Proxmox containers. I would like to know if anyone has seen any ready to run proxmox images that include freeswitch so we can test a number of things without having to deeply go into creating our own. Or at least a clue to which system images/distro images we can use to quickly get it installed not having to deal with too many dependency or different Linux version issues. Just to be clear: It should be for a more or less current Proxmox and current freeswitch. I am not looking forward to use the KVM mode but would consider it, if it is otherwise ready to run out of the box. I would rather use a real OpenVZ based container. Thanks for anyone helping!

• Real-time threat finder

  - by Rohit

  I want to make a small program that is capable to download files from the cloud onto my system. As the file reaches my system, another program on my system will analyze the file and try to find suspicious behaviors in it. I want to make a system similar to ThreatExpert (www.threatexpert.com). The suspicious data gathered by my program will be sent to Anti-Virus companies for analysis. I want to know whether this program can be written in .NET or as a PHP website. I have no experience of Cloud computing. How to retrieve files from the cloud?

• Dynamic VPN tunneling technologies

  - by Adam

  Ok, so I'm asking a more specific question this time. I'm writing a paper about Cisco's DMVPN and one of the tasks I have is to make the analysis of available network solutions which use dynamic VPN tunnels. Because the paper is about DMVPN, I have to compare those solutions to it. I know there are a lot of dynamic tunneling technologies but I'm looking for ones that can be compared to DMVPN. So the question is: are there any technologies which use dynamic VPN tunnels (not necessarily using crypto) that can be compared to DMVPN? What are those technologies?

• Need Help Debugging BSOD

  - by nmuntz

  For the last few days I've been getting a BSOD at least once a day. Apparently the crash has been caused by ntkrpamp.exe and searching on google has revealed that the issue seems to be related to bad RAM. I have run memtest and my RAM modules have no errors on them. I'm pretty sure the issue is related to drivers, but I can't figure out which one. I'm not an expert in interpreting the output of windbg so any pointers would be greatly appreciated. Here is my analysis with WinDbg. It was too long to paste it here. One strange thing i noticed is that my Windows XP is in Spanish (SP3) and ntkrpamp.exe copyright info seems to be in portuguese. Not sure if that could be an issue, perhaps i have the wrong ntkrpamp.exe... Thanks a lot in advance

• Setting up Dependencies for Nagios

  - by hfranco

  I'm trying to setup dependencies for a router and several servers. What I want to do is setup the router as the Master Host so if the router fails all other services on the servers won't alert. Unfortunately this is easier said than done. Is there an easy way to setup service dependencies for all services on a server for a Master Host (or my router)? Nagios has some documentation but it will be extremely time consuming to add a single service dependency definition for every service. http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#servicedependency

• Installing Java 6 on Ubuntu 10.04 fails on missing Java 6 JRE package

  - by David S

  I'm trying to install Java 6 on Ubuntu 10.04 and it's been harder than it should be. In another question about installing Java on Ubuntu/Linux it said that I needed to do the following: sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner" However, that failed and I kept getting: sudo: add-apt-repository: command not found The solution to this, was to run: sudo apt-get install python-software-properties So, that seemed to work and the command above to "add-apt-repository" seems to complete with no errors. And I have run the following to confirm it got added. sudo vi /etc/apt/sources.list But, now when I run the following: sudo apt-get install sun-java6-jre I get: Reading package lists... Done Building dependency tree Reading state information... Done Package sun-java6-jre is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package sun-java6-jre has no installation candidate Where do I go from here?

• A good log file analyzer for windows

  - by Raminder

  Is there a text-editor for windows that can open for me first n lines of a large file? It would be nice if it could also open a set of lines from the middle of the file. EDIT: Basically my requirement is that I want to analyze huge(2GB) log files. So any good tool that can open huge files with some analysis capabilities(searching, text highlighting etc.) would be nice. I like notepad++ but it wouldn't open a file even of about 650 MB. P.S. - Open source tools will be preferred.

• CGI error from PHP when running exec() on IIS

  - by Patrick

  Windows Server 2003 x64 PHP 5.2 IIS 6.0 The program Ink2Png.exe is set with Everyone-Read and Execute permissions. As does its dependency (microsoft.ink.dll) PHP Safe Mode is off exec() is passed [the full exe path], space, [full path to another file] This other file also has full read permissions. The output directory has full write permissions. As soon as exec() is hit, the connection dies, the browser does not even receive a full set of http headers, and it reports a CGI error. Examining the output, it appears the program was not even run. Any ideas? How can I figure out what exactly is happening and get it running again? EDIT: Also, it is a .NET application, if that is significant in any way.
