  • Advice on selecting programming languages to concentrate on? (2nd year IT security student)

    - by Tyler J Fisher
    I'm in the process of considering which programming languages I should devote the majority of my coding studies to. I'm a 2nd year CS student, majoring in IT security. What I want to do/work with: Intelligence gathering Relational databases Virus design Snort network IPS Current coding experience (what I'm going to keep): Java - intermediate HTML5 - intermediate SQL (MySQL, Oracle 11g) - basic BASH - basic I'm going to need to learn (at least) one of the following languages in order to be successful in my field. Languages to add (at least 1): Ruby (+Metasploit) C++ (virus design, low-level driver interaction, computationally intensive applications) Python (import ALL the things) My dilemma: If I diversify too broadly, I won't be able to focus on, and improve in a specific niche. Does anyone have any advice as to how I should select a language? What I'm considering + why I'm leaning towards Ruby because of Metasploit support, despite lower efficiency when compared to Python. Any suggestions based on real-world experience? Should I focus on Ruby, Python, or C++? Both Ruby, and Python have been regarded as syntactically similar to Java which my degree is based around. I'm going to be studying C++ in two years as a component of my malicious code class. Thanks, Tyler

  • MS Bing web crawler out of control causing our site to go down

    - by akaDanPaul
    Here is a weird one that I am not sure what to do. Today our companies e-commerce site went down. I tailed the production log and saw that we were receiving a ton of request from this range of IP's 157.55.98.0/157.55.100.0. I googled around and come to find out that it is a MSN Web Crawler. So essentially MS web crawler overloaded our site causing it not to respond. Even though in our robots.txt file we have the following; Crawl-delay: 10 So what I did was just banned the IP range in iptables. But what I am not sure to do from here is how to follow up. I can't find anywhere to contact Bing about this issue, I don't want to keep those IPs blocked because I am sure eventually we will get de-indexed from Bing. And it doesn't really seem like this has happened to anyone else before. Any Suggestions? Update, My Server / Web Stats Our web server is using Nginx, Rails 3, and 5 Unicorn workers. We have 4gb of memory and 2 virtual cores. We have been running this setup for over 9 months now and never had an issue, 95% of the time our system is under very little load. On average we receive 800,000 page views a month and this never comes close to bringing / slowing down our web server. Taking a look at the logs we were receiving anywhere from 5 up to 40 request / second from this IP range. In all my years of web development I have never seen a crawler hit a website so many times. Is this new with Bing?

  • What are Information Centers?

    - by user12244613
    Information Centers are similar to product pages in the Oracle Sun System Handbook Many customers like the Oracle Sun System Handbook concept of a home page with all the product attributes, troubleshooting etc. access from a single home page. This concept is now available for a range of Oracle Solaris, Systems, and Storage products. The Information Center for each product covers areas such as: Overview, Hot Topics, Patching and Maintenance. The Information Center pages are dynamically generated each night to ensure the latest content is available to you. Here are the top Solaris, Systems, and Storage Information Centers: Oracle Explorer Data Collector Oracle Solaris 10 Live Upgrade Oracle Solaris 11 Booting Information Center Oracle Solaris 11 Desktop and Graphics Information Center Oracle Solaris 11 Image Packaging System (IPS) Information Center Oracle Solaris 11 Installation Information Center Oracle Solaris 11 Product Information Center Oracle Solaris 11 Security Information Center Oracle Solaris 11 System Administration Information Center Oracle Solaris 11 Zones Information Center Oracle Solaris Crash Analysis Tool(SCAT) - Information Center Oracle Solaris Cluster Information Center Oracle Solaris Internet Protocol Multipathing (IPMP) Information Center Oracle Solaris Live Upgrade Information Center Oracle Solaris ZFS Information Center Oracle Solaris Zones Information Center CMT T1000/T2000 and Netra T2000 CMT T5120/T5120/T5140/T5220/T5240/T5440 Systems M3000/M4000/M5000/M8000/M9000-32/M9000-64 Management and Diagnostic Tools for Oracle Sun Systems Netra CT410/810 and Netra CT900 Network-Attached Storage (NAS) Oracle Explorer Data Collector Oracle VM Server for SPARC (LDoms) Pillar Axiom 600 SL3000 Tape Library Sun Disk Storage Patching and Updates Sun Fire 3800/4800/4810/6800/E2900/E4900/E6900/V1280 - Netra 1280/1290 Sun Fire 12K/15K/E20K/E25K Sun Fire X4270 M2 Server Sun x86 Servers T3 and T4 Systems Tape Domain Firmware V210/V240/V440/V215/V245/V445 Servers VSM (VTSS/VLE/VTCS)

  • A bounce-rate attack to manipulate SEO ?

    - by Denis Volovik
    This is a question to experienced people that might help us shed some light on the issue. We noticed a very strange behavior on our site, in Google Analytics. Some dude from Finland, namely, from Kouvola city is hitting one of our pages - only one page on our site, 'bout a hundred times per day, all with an average bounce rate of 90%+... This is causing our overall bounce rate to go up by 1 to 3% per day... which is very disturbing.. since we're trying to do our best in order to keep it as low as possible. And obviously having it jumped from ~24% to 27%, just because of that crazy dude is not making us happy at all... We tried implementing a geo-targeted script in order to catch this particular visitor and deliver him a juicy message, and it seemed like it helped in the beginning, it has stopped for a day or two, but now he's back... The geo-targeted script was also logging all IP addresses for page requests originating from Finland in order to find out more details and (in order to block them on the server level, later).. but thing is, it was all mainly cable or DSL connections with various, but not constantly repeating IPs... we are all wondering what is he up to really ? I think that this page should be kept updated with ideas on how to combat this and perhaps someone could also shed light on what it might be ? What is the reason for doing this "bounce-rate attack", as I call it? There was a similar question asked on stackoverflow earlier, with no meaningful answer - here - How to stop bounce rate manipulation.

  • Advice for programming a lobby for a network multiplayer game?

    - by Milo
    I'm working on learning network programming. I'm working on a simple card game. The basic idea is: Players enter the lobby Players see tables Players sit at an empty seat Once they sit, they do not need any information from the lobby, they see the card table and the data about the other players and so forth. I've programmed the server portion for the game itself. The clients connect to my server object and the server then receives and sends messages; quite simple. The tricky concepts for me are: What's a good way to run many tables at the same time? What's a good way to keep the lobby consistently updated for each person in the lobby (eg: MSG_TABLE_FILLED, 22) Ideally I'd like to have 1 server exe for all of this and to have to deal with multithreading as little as possible. I'm going to use the enet library. I was thinking that each time a game session starts, I push a new Game and I map the client IPs to that table, then I just route messages from those clients to that Game. Since enet supports channels I was thinking of using 2 channels per table, one for the game messages and one for in game chat. Would something like this work? Does anyone have any advice / design ideas for a game with a lobby and many tables? Is there a usual way this is done that I'm overlooking? Any conceptual ideas or even c/c++ code examples would be very helpful. Thanks

    Mit Solaris 11 bringt Oracle das erste Betriebssystem für die Cloud auf den Markt. Wir hatten es angekündigt, das Thema Cloud wird uns hier im Blog so schnell nicht loslassen: Am Freitag hat nun Oracle sein erstes Unix-Betriebssystem auf den Markt gebracht, das explizit für die Cloud designt wurde: Solaris 11 heißt es und hier ist die Assoziation zu Stanislaw Lems gleichnamigem Science Fiction-Roman durchaus angebracht: Schließlich gilt Cloud Computing als die Technologie der Zukunft schlechthin. Was bietet Solaris 11, welchen Nutzen können die Oracle Partner daraus ziehen? "Kunden können ihre Betriebsabläufe vereinfachen, die Kapazitäten ihrer Rechenzentren erhöhen und Unternehmensanwendungen von Oracle und anderen in einer sicheren, skalierbaren Cloud oder in einer klassischen Unternehmensumgebung laufen lassen“, fasst John Fowler, Executive Vice President, Systems zusammen. Darf‘s auch etwas konkreter sein? Bitte: Oracle Solaris 11 dient ganz einfach dazu, selbst anspruchsvollste Unternehmensanwendungen in privaten, hybriden und Public Clouds zu betreiben. Als vollständig virtualisiertes Betriebssystem verfügt es über integrierte Virtualisierungs-Funktionen, sowohl für Betriebssystem- als auch für Netzwerk- und Speicher-Ressourcen. Die Server-Virtualisierung sorgt für sichere Live-Migration und flexible Einsatzmöglichkeiten – basierend auf Oracle VM für x86- und SPARC-Systeme. Höchste Verfügbarkeit wird erreicht, indem Solaris 11 ein umfassendes Management über die gesamte Infrastruktur hinweg ermöglicht. Oracle Solaris 11 bietet bereits im Standardbetrieb aktive Sicherheit „by default“, wie rollenbasierten Root-Zugriff und Überwachungsfunktionen. Die Daten- und Speichermanagement-Basis für Oracle Solaris 11 ist Oracle Solaris ZFS. Neben garantierter Datenintegrität erlaubt das Tiered Storage das Einrichten von Pools mit Flash-Speicher und zudem Hochgeschwindigkeitsverschlüsselung. Ein Blick in die Presse zeigt, dass Solaris 11 durchaus für Aufsehen in der Fachwelt sorgt, so äußert sich etwa die Netzwelt sehr positiv: „Die neue Paketverwaltung IPS trägt wie die genannten Neuerungen dazu bei, dass Solaris es in Version 11 durchaus wieder mit den etablierten Linux-Distributionen aufnehmen kann. Das Betriebssystem macht nicht nur im Server-, sondern auch im Desktop-Einsatz eine sehr gute Figur und glänzt mit hoher Stabilität.“ Hier die direkten Links zu weiteren Berichten über Solaris11 in der Fachpresse: Heise onlineZDNetGolem.deSilicon.deAll about SECURITYIT DirectorPro-Linux.deTech ChannelLinux Magazin

  • Which problem(s) do YOU want to see solved?

    - by buu700
    My team and I are meeting tonight to come up with a business plan and some community input would be amazing. I've been mulling over this issue for the past few months and bouncing ideas off of others, and now I'd finally like some input from the community. I have come up with a fair selection of ideas, but most of those amount to either fun projects which could potentially be profitable, or otherwise solid business models that have one or two major hurdles (usually related to resources or legality). For our team meeting tonight, my idea is to take inventory of our available skills, resources, and compelling problems which interest us. The last is where I would greatly appreciate some community input. Hell, even entire business ideas/plans would be appreciated. No matter how big or small your thoughts, any input would be appreciated. We're a team of computer scientists, so our business will be primarily based around software/technology/Web solutions. Among my relevant available resources (entire Internet aside), I have the following: A pretty reliable connection to an SEO company a large production company. A stash of fairly powerful server hardware. A fast network with static IPs. The backend for Hackswipe, which includes credit card payment processing and a Google Voice-based SMS gateway. This work in progress design for something completely unrelated but which is backed by some fairly decent infrastructure. Direct access to the experts in just about any relevant field (on-campus Carnegie Mellon professors). A sexual relationship with the baron of a small nation. For further down the line, some investor relationships. Not likely to be so relevant, but a decent social media presence (Stack Overflow reputation, modship in some major reddits, various tech forums). The source code for Eugene fucking McCabe. Pooled with the other team members, the list of projects we can build off of would be longer (including an Android app). So, what are your thoughts? Crossposted to reddit

  • I need advice on laptop purchase for university [closed]

    - by Systemic33
    I'm currently in University studying Computer Science/IT/Information Technology. And this first year i've managed to do with the laptop I had; an ASUS Eee PC 1000H with a 10.1" screen. But this is getting way too underpowered and small for programming more than just quick programming introduction excercises. So I'm looking to buy a more suitable laptop. It's not supposed to be a desktop replacement though, since I've got a pretty good desktop already with a 24" monitor. So the kinda laptop I want to buy is one suited for university. If this bears any significance, I'm working in Java atm, but I will likely work with lots of other things incl. web development. I'm looking to spend about $1700 plus/minus. And it should be powerful/big enough for working on programming projects as well as the usual university stuff like MATLAB, Maple, etc out "in the field", and sometimes for maybe a week when visiting my parents. What I'm looking at right now is the ASUS Zenbook UX31A with the 1920 x 1080 resolution on 13.3" IPS display. But I'm kinda nervous that this will be too petite for programming. In essence i'm looking for a powerfull computer, that has good enough battery, and looks good. I would love suggestions or any type of feedback, either with maybe a better choice, or input on how its like programming on 13" laptops. Very much thanks in advance for anyone who even went through all that! PS. I don't want a mac, or my inner karma would commit Seppuku xD But experiences from working on the 13" Macbook Air would kinda be equivalent to the Zenbook i'm considering, so I would love to hear that. tl;dr The quick brown fox jumps over the lazy dog ;)

  • New Oracle Solaris 11 Administration book

    - by glynn
    During the development of Oracle Solaris 11, one of the main goals was to modernize the operating system and remove some of the existing frustrations that our administrative audience had in deploying and using the platform within data centers around the world. That meant a comprehensive clean out of some existing technologies to provision the operating system (replacing Jumpstart with Automated Installer) and manage system software (replacing SVR4 with IPS packaging), consolidate the vast spectrum of networking configuration, and enhance the user environment to provide familiarity for those who were used to administering Linux environments among many other things. While some considered the changes to Oracle Solaris 11 as a negative change, most will be impressed at how far we've come - the deeper integration of key technologies, presented in a consolidated and consistent form. It is easier to administer the Oracle Solaris platform that ever before, and I have no doubt that administrators coming from other platforms will be hugely impressed with what they see, especially if they're judging based on past experiences of Solaris 8 and Solaris 9. In fact I'd go further to say that Oracle Solaris 11 is a more powerful, integrated and usable platform that most Linux platforms I've seen. But as with anything, there's always an initial learning curve to get through. We've provided a significant selection of learning materials out on the Oracle Solaris 11 pages on Oracle Technology Network and some great training and certification options. One more option is now available in the form of a book, the Oracle Solaris 11 System Administration The Complete Reference. This provides an exceptional reference to help administrators learn about Oracle Solaris 11, especially those who have come from the Linux platform. As is quoted in the first chapter of the guide: Linux users and developers will find in Oracle Solaris 11 a familiar and quickly productive working environment; we point out similarities and differences between the Linux and Solaris kernels and system administration tools, and describe how typical open source Web development tasks are accomplished in this OS. So I would encourage you to take a read of it and start seriously considering Oracle Solaris 11 to be a platform choice for your data center. Oracle Solaris 11 System Administration The Complete Reference - yours for only $32.50 (if you successfully use the promotion code - otherwise worth shopping around to pick up a good deal).

  • Why do people crawl sites without downloading pictures?

    - by Michael
    Let me show you what I mean: IP Pages Hits Bandwidth 85.xx.xx.xxx 236 236 735.00 KB 195.xx.xxx.xx 164 164 533.74 KB 95.xxx.xxx.xxx 90 90 293.47 KB It's very clear that these person are crawling my site with bots. There's no way that you could visit my site and use <1MB bandwidth. You might say that there's the possibility that they could be browsing the site using some browser or plug-in that does not download images, js/css files, etc., but the simple fact of the matter is that there are not 90-236 pages that are linked from the home page (outside of WP files), even if you visited every page twice. I could understand if these people were crawling the site for pictures, but once again, the bandwidth indicates that this isn't what is happening. Why, then, would they crawl the site to simply view the HTML/txt/js/etc. files? The only thing that I can come up with is that they are scanning for outdated versions of WordPress, SQL injection vulnerabilities, etc., which makes me inclined to outright ban the IPs, but I'm curious, is it possible that this person is a legitimate user, or at the very least, not intending to be harmful?

  • RDA and Fusion Middleware Diagnostic Framework Integration

    - by Daniel Mortimer
    Further to my last blog entry "FMw Diagnostic Framework : Automatic Capture of Diagnostic Data Upon First Failure!" I have spent some time exploring how Remote Diagnostic Agent (RDA) integrates with Diagnostic Framework. Remote Diagnostic Agent, by default, collects the information about the last 10 incidents which have been captured in the Automatic Diagnostic Repository (ADR). This information can be located via RDA's Start Page Menu system. See screenshot below. Screenshot - Viewing Diagnostic Framework Incident Information in a RDA Package Note: In the next release of RDA - version 4.30 - the Diagnostic Repository menu label will have it's own position in the weblogic managed server sub menu hierarchy rather than be a child menu item of the logs menuDiagnostic Framework is also capable of launching RDA engine and including the output in an incident package. This is achieved via the command "IPS GENERATE PACKAGE". The RDA output is written to DOMAIN_HOME/servers/<server name>/adr/diag/ofm/<domain name>/<server name>/incpkg/pkg_[number]/seq_[number]/rda The RDA collected files are best viewed (as shown in the screenshot above) by opening the RDA Start Page - "DFW__start.htm" - from this directory in a browser. If you do not have a browser available on the host machine, zip the contents of the rda directory and transfer and extract to a machine which has a browser.  The explanation of the integration goes a little deeper. If you want to know more, read My Oracle Support document: Understanding RDA and FMW 11g Diagnostic Framework Integration [Document 1503644.1]

  • An adequate message authentication code for REST

    - by Andras Zoltan
    My REST service currently uses SCRAM authentication to issue tokens for callers and users. We have the ability to revoke caller privileges and ban IPs, as well as impose quotas to any type of request. One thing that I haven't implemented, however, is MAC for requests. As I've thought about it more, for some requests I think this is needed, because otherwise tokens can be stolen and before we identify this and deactivate the associated caller account, some damage could be done to our user accounts. In many systems the MAC is generated from the body or query string of the request, however this is difficult to implement as I'm using the ASP.Net Web API and don't want to read the body twice. Equally importantly I want to keep it simple for callers to access the service. So what I'm thinking is to have a MAC calculated on: the url, possibly minus query string the verb the request ip (potentially is a barrier on some mobile devices though) utc date and time when the client issues the request. For the last one I would have the client send that string in a request header, of course - and I can use it to decide whether the request is 'fresh' enough. My thinking is that whilst this doesn't prevent message body tampering it does prevent using a model request to use as a template for different requests later on by a malicious third party. I believe only the most aggressive man in the middle attack would be able to subvert this, and I don't think our services offer any information or ability that is valuable enough to warrant that. The services will use SSL as well, for sensitive stuff. And if I do this, then I'll be using HMAC-SHA-256 and issuing private keys for HMAC appropriately. Does this sound enough? Have I missed anything? I don't think I'm a beginner when it comes to security, but when working on it I always. am shrouded in doubt, so I appreciate having this community to call upon!

  • Domain changes required for SSL integration

    - by user131003
    Currently my site supports regular payment options (User is taken to Payment Gateway/PG website). Now I'm trying to implement "seamless" PG integration. I need SSL for this. I'm having a dedicated server with 5 static IPs from Hostgator/HG. options: I take SSL for www.my_domain.com. According to HG, I need to change IP of main site as current IP is not really dedicated as it is being shared by cpanel etc. So They need to bind another dedicated IP to main domain for SSL to work. This would required DNS change for main website and hence cause few hours downtime (which is ok). I've noticed that most of the e-commerce websites are using subdomains like secure.my_domain.com for ssl/https. This sounds like a better approach. But I've got few doubts in this case: a) Would I need to re-register with existing PGs (Paypal, Google Checkout, Authorize.net) if I switch to subdomain? Re-registering is not an option for me. b) Would DNS change be required for www.my_domain.com in this case. This confusion arose because of following reply from HG : "If the sub domain secure.my_domain.com is added to an existing cPanel it will use the IP for that cPanel so as long as it is a Dedicated IP that will be fine. If secure.my_domain.com gets setup as its own cPanel it will need to be assigned to a Dedicated IP which would have a DNS change involved.". Please suggest?

  • Reaping the Benefits of the Image Packaging System

    - by rickramsey
    source One of the promises made about Oracle Solaris 11 was easier installation. Remember? Do you also remember how involved installing Oracle Solaris Cluster used to be? It was so involved, in fact, that we (when we were Sun Microsystems) wouldn't even let you do it yourself. How times have changed. New - How to Automate The Installation of Oracle Solaris Cluster 4.0 Thanks to the new image packaging architecture in Oracle Solaris 11, you can now automate the installation of Oracle Solaris Cluster 4.0. Why is that such a big deal? As Lucia Lai explains it: "Without the AI, you would have to manually install the cluster components on the cluster nodes, and then run the scinstall tool to add the nodes to the cluster. If, instead, you use the AI, both the Oracle Solaris 11 and the Oracle Solaris Cluster 4.0 packages are installed onto the cluster nodes directly from Image Packaging System (IPS) repositories, and the nodes are booted into a new cluster with minimum user intervention." Lucia goes on to explain how to set up and configure the AI server, how to plan your cluster configuration for the automated installation, how to use the scinstall utility, how to set up the DHCP server, and more. A thorough, well-written article. - Rick Website Newsletter Facebook Twitter

  • Network: Incoming connections work, outgoing fails

    - by anirvan
    i recently set up my own server at home to run Ubuntu 12.04 server ed. on booting up, i noticed that a message related to networking comes up, and the booting process pauses. the message read something like - waiting for network configuration and after a while - waiting another 60 seconds... on booting up, I realised that any command which requires a network connection was not working - ping, apt-get install, etc. on firing the ifup eth0 command, I get the error RTNETLINK answers: File exists. Failed to bring up eth0. I also realised, while searching the web for this problem, that this is probably one of the most common networking related issues - however, most of the questions are around setting up multiple IPs for the same machine. ifdown eth0 also fails, stating that eth0 is not configured. my /etc/network/interfaces file has a simple configuration for a static IP: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx gateway xx.xx.xx.xx dns-nameservers xx.xx.xx.xx The strangest part of this problem is that, while I can't connect to anything outside, I can ping to this particular server using the static IP configured in the interface file, and, i can even SSH into it! I'm really at ends here with this problem, and any guidance is much appreciated. Thanks!

  • use subdomain on different host

    - by Roy
    I want to accomplish something that I thought was simple. My wish is as follows: I have a domainname with hosting, a WordPress multisite (with subfolder setup) installed and running: gangleri.nl. I have another domain at another host and without hosting: monas.nl I created a subdomain on gangleri.nl: monas.gangleri.nl and the domain redirects to that subdomain. Now what I want is to have monas.nl act like a website, not a website in a subdomain. I would like to have post urls as in monas.nl/posttitle. I first thought to do this with the DNS settings of Monas.nl. I now have an URL forward, CURL is not what I want and I did not manage to get A-records or CNAMEs to work. I tried using the htaccess file of the WP installation in monas.gangleri.nl. I tried 301, rewrite and whatnot, but also without success. Meanwhile, I have been reading so much that I no longer have a clue what to do. A-record doesn't sound probable, since I have no IP for the subdomain, so an A-record would point to gangleri.nl rather than using the subdomain. Also I have no idea if I should do something in the DNS settings of gangleri.nl or monas.nl, both, one of them and something somewhere else. I have the idea that I've tried everything, but the more I try and read about it, the less I can get my head around. People talking about A-records to subdomains while I can only use IPs, CNAME settings that my host doesn't support or something. Could somebody tell me if what I want is possible and if so, take me by the hand and guide me through it?

  • Solution for lightweight LAN peer discovering?

    - by DevilWithin
    I built a library for purely cross-platform programming. My games made with it run fine in Android , Pc, Linux, Mac etc. The networking capabilities are provided by ENET library, therefore all communication between my apps is not TCP or UDP compatible, but only in the custom protocol, even tough its based on the UDP ultimately. I don't think its possible to do what i want with ENET, thats why I ask here for help! Lets say I have the same game running in my Android phone, my laptop and my pc. They are all in the same wifi network, and therefore in a LAN, whether its Wifi hotspot(?) or the household router. I need each of those 3 peers to discover the other two in the network. This is meant only to find the IP of alive apps in the LAN network, to be able to host multiplayer games between them. I can only think of one effective way to do this, UDP broadcast, wait responses, but if that is the solution, i need something small, since its the only purpose of the implementation. Other way could be to try to connect to all IPs in the LAN address subrange, but I don't think the OS would be with me on this one :p Sorry for the long question!

  • Dell M4600 with nVidia Quadro 2000M hangs on boot when external monitor is connected

    - by vladeta
    I have a problem with my fresh installed Ubuntu 12.04 LTS on my Dell M4600: nVidia quadro 2000M i7-2860 16GB ram 128GB SSD Dell/Samsung 750GB HDD IPS RGB laptop display When it is connected via DP++ to the external Dell U2311H monitor, it hangs on boot or when wakening from suspend. If I detach the DP cable it boots normally. I have tried all combinations that I have found, as adding to grub: "no splash", "boot=pci", "acpi=off", etc... I have also changed in nVidia X settings that external monitor is the primary one and also tried to delete monitor.xml file. There is no change it hangs each time after grub. It starts to load daemons then both screens are blank and then completely hangs with beep sound. What I discovered is if I detach the cable and wait for about 2 sec after grub starts booting and then physically connect DP cable while the Ubuntu is still booting everything works normally and I have a picture on my external screen while the laptop screen is off, just as I wanted. Do you maybe know how to solve this issue? Thank You.

  • Unable to free space in /boot

    - by wadesworld
    Running: Linux ips-svf-1 3.0.0-22-server #36-Ubuntu SMP Tue Jun 12 17:56:20 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I'm trying to free space in /boot with apt-get -y purge, but every time I run the command I get an error about unmet dependencies: sudo apt-get -y purge linux-headers-3.0.0-12 Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: linux-headers-3.0.0-12-server : Depends: linux-headers-3.0.0-12 but it is not going to be installed linux-image-server : Depends: linux-image-3.0.0-26-server but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). However, I can't run apt-get -f install since /boot is full. I also tried running dpkg --purge and dpkg --remove manually, but both give the same unmet dependency error. Any suggestions on how I can successfully free space in /boot? Is there anything I can delete with rm?

  • Solaris 11.1: Changes to included FOSS packages

    - by alanc
    Besides the documentation changes I mentioned last time, another place you can see Solaris 11.1 changes before upgrading is in the online package repository, now that the 11.1 packages have been published to http://pkg.oracle.com/solaris/release/, as the “0.175.1.0.0.24.2” branch. (Oracle Solaris Package Versioning explains what each field in that version string means.) When you’re ready to upgrade to the packages from either this repo, or the support repository, you’ll want to first read How to Update to Oracle Solaris 11.1 Using the Image Packaging System by Pete Dennis, as there are a couple issues you will need to be aware of to do that upgrade, several of which are due to changes in the Free and Open Source Software (FOSS) packages included with Solaris, as I’ll explain in a bit. Solaris 11 can update more readily than Solaris 10 In the Solaris 10 and older update models, the way the updates were built constrained what changes we could make in those releases. To change an existing SVR4 package in those releases, we created a Solaris Patch, which applied to a given version of the SVR4 package and replaced, added or deleted files in it. These patches were released via the support websites (originally SunSolve, now My Oracle Support) for applying to existing Solaris 10 installations, and were also merged into the install images for the next Solaris 10 update release. (This Solaris Patches blog post from Gerry Haskins dives deeper into that subject.) Some of the restrictions of this model were that package refactoring, changes to package dependencies, and even just changing the package version number, were difficult to do in this hybrid patch/OS update model. For instance, when Solaris 10 first shipped, it had the Xorg server from X11R6.8. Over the first couple years of update releases we were able to keep it up to date by replacing, adding, & removing files as necessary, taking it all the way up to Xorg server release 1.3 (new version numbering begun after the X11R7 split of the X11 tree into separate modules gave each module its own version). But if you run pkginfo on the SUNWxorg-server package, you’ll see it still displayed a version number of 6.8, confusing users as to which version was actually included. We stopped upgrading the Xorg server releases in Solaris 10 after 1.3, as later versions added new dependencies, such as HAL, D-Bus, and libpciaccess, which were very difficult to manage in this patching model. (We later got libpciaccess to work, but HAL & D-Bus would have been much harder due to the greater dependency tree underneath those.) Similarly, every time the GNOME team looked into upgrading Solaris 10 past GNOME 2.6, they found these constraints made it so difficult it wasn’t worthwhile, and eventually GNOME’s dependencies had changed enough it was completely infeasible. Fortunately, this worked out for both the X11 & GNOME teams, with our management making the business decision to concentrate on the “Nevada” branch for desktop users - first as Solaris Express Desktop Edition, and later as OpenSolaris, so we didn’t have to fight to try to make the package updates fit into these tight constraints. Meanwhile, the team designing the new packaging system for Solaris 11 was seeing us struggle with these problems, and making this much easier to manage for both the development teams and our users was one of their big goals for the IPS design they were working on. Now that we’ve reached the first update release to Solaris 11, we can start to see the fruits of their labors, with more FOSS updates in 11.1 than we had in many Solaris 10 update releases, keeping software more up to date with the upstream communities. Of course, just because we can more easily update now, doesn’t always mean we should or will do so, it just removes the package system limitations from forcing the decision for us. So while we’ve upgraded the X Window System in the 11.1 release from X11R7.6 to 7.7, the Solaris GNOME team decided it was not the right time to try to make the jump from GNOME 2 to GNOME 3, though they did update some individual components of the desktop, especially those with security fixes like Firefox. In other parts of the system, decisions as to what to update were prioritized based on how they affected other projects, or what customer requests we’d gotten for them. So with all that background in place, what packages did we actually update or add between Solaris 11.0 and 11.1? Core OS Functionality One of the FOSS changes with the biggest impact in this release is the upgrade from Grub Legacy (0.97) to Grub 2 (1.99) for the x64 platform boot loader. This is the cause of one of the upgrade quirks, since to go from Solaris 11.0 to 11.1 on x64 systems, you first need to update the Boot Environment tools (such as beadm) to a new version that can handle boot environments that use the Grub2 boot loader. System administrators can find the details they need to know about the new Grub in the Administering the GRand Unified Bootloader chapter of the Booting and Shutting Down Oracle Solaris 11.1 Systems guide. This change was necessary to be able to support new hardware coming into the x64 marketplace, including systems using UEFI firmware or booting off disk drives larger than 2 terabytes. For both platforms, Solaris 11.1 adds rsyslog as an optional alternative to the traditional syslogd, and OpenSCAP for checking security configuration settings are compliant with site policies. Note that the support repo actually has newer versions of BIND & fetchmail than the 11.1 release, as some late breaking critical fixes came through from the community upstream releases after the Solaris 11.1 release was frozen, and made their way to the support repository. These are responsible for the other big upgrade quirk in this release, in which to upgrade a system which already installed those versions from the support repo, you need to either wait for those packages to make their way to the 11.1 branch of the support repo, or follow the steps in the aforementioned upgrade walkthrough to let the package system know it's okay to temporarily downgrade those. Developer Stack While Solaris 11.0 included Python 2.7, many of the bundled python modules weren’t packaged for it yet, limiting its usability. For 11.1, many more of the python modules include 2.7 versions (enough that I filtered them out of the below table, but you can always search on the package repository server for them. For other language runtimes and development tools, 11.1 expands the use of IPS mediated links to choose which version of a package is the default when the packages are designed to allow multiple versions to install side by side. For instance, in Solaris 11.0, GNU automake 1.9 and 1.10 were provided, and developers had to run them as either automake-1.9 or automake-1.10. In Solaris 11.1, when automake 1.11 was added, also added was a /usr/bin/automake mediated link, which points to the automake-1.11 program by default, but can be changed to another version by running the pkg set-mediator command. Mediated links were also used for the Java runtime & development kits in 11.1, changing the default versions to the Java 7 releases (the 1.7.0.x package versions), while allowing admins to switch links such as /usr/bin/javac back to Java 6 if they need to for their site, to deal with Java 7 compatibility or other issues, without having to update each usage to use the full versioned /usr/jdk/jdk1.6.0_35/bin/javac paths for every invocation. Desktop Stack As I mentioned before, we upgraded from X11R7.6 to X11R7.7, since a pleasant coincidence made the X.Org release dates line up nicely with our feature & code freeze dates for this release. (Or perhaps it wasn’t so coincidental, after all, one of the benefits of being the person making the release is being able to decide what schedule is most convenient for you, and this one worked well for me.) For the table below, I’ve skipped listing the packages in which we use the X11 “katamari” version for the Solaris package version (mainly packages combining elements of multiple upstream modules with independent version numbers), since they just all changed from 7.6 to 7.7. In the graphics drivers, we worked with Intel to update the Intel Integrated Graphics Processor support to support 3D graphics and kernel mode setting on the Ivy Bridge chipsets, and updated Nvidia’s non-FOSS graphics driver from 280.13 to 295.20. Higher up in the desktop stack, PulseAudio was added for audio support, and liblouis for Braille support, and the GNOME applications were built to use them. The Mozilla applications, Firefox & Thunderbird moved to the current Extended Support Release (ESR) versions, 10.x for each, to bring up-to-date security fixes without having to be on Mozilla’s agressive 6 week feature cycle release train. Detailed list of changes This table shows most of the changes to the FOSS packages between Solaris 11.0 and 11.1. As noted above, some were excluded for clarity, or to reduce noise and duplication. All the FOSS packages which didn't change the version number in their packaging info are not included, even if they had updates to fix bugs, security holes, or add support for new hardware or new features of Solaris.

  • How to stop registration attempts on Asterisk

    - by Travesty3
    The main question: My Asterisk logs are littered with messages like these: [2012-05-29 15:53:49] NOTICE[5578] chan_sip.c: Registration from '<sip:[email protected]>' failed for '37.75.210.177' - No matching peer found [2012-05-29 15:53:50] NOTICE[5578] chan_sip.c: Registration from '<sip:[email protected]>' failed for '37.75.210.177' - No matching peer found [2012-05-29 15:53:55] NOTICE[5578] chan_sip.c: Registration from '<sip:[email protected]>' failed for '37.75.210.177' - No matching peer found [2012-05-29 15:53:55] NOTICE[5578] chan_sip.c: Registration from '<sip:[email protected]>' failed for '37.75.210.177' - No matching peer found [2012-05-29 15:53:57] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device <sip:[email protected]>;tag=cb23fe53 [2012-05-29 15:53:57] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device <sip:[email protected]>;tag=cb23fe53 [2012-05-29 15:54:02] NOTICE[5578] chan_sip.c: Registration from '<sip:[email protected]>' failed for '37.75.210.177' - No matching peer found [2012-05-29 15:54:03] NOTICE[5578] chan_sip.c: Registration from '<sip:[email protected]>' failed for '37.75.210.177' - No matching peer found [2012-05-29 21:20:36] NOTICE[5578] chan_sip.c: Registration from '"55435217"<sip:[email protected]>' failed for '65.218.221.180' - No matching peer found [2012-05-29 21:20:36] NOTICE[5578] chan_sip.c: Registration from '"1731687005"<sip:[email protected]>' failed for '65.218.221.180' - No matching peer found [2012-05-30 01:18:58] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device "unknown" <sip:[email protected]>;tag=dEBcOzUysX [2012-05-30 01:18:58] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device "unknown" <sip:[email protected]>;tag=9zUari4Mve [2012-05-30 01:19:00] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device "unknown" <sip:[email protected]>;tag=sOYgI1ItQn [2012-05-30 01:19:02] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device "unknown" <sip:[email protected]>;tag=2EGLTzZSEi [2012-05-30 01:19:04] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device "unknown" <sip:[email protected]>;tag=j0JfZoPcur [2012-05-30 01:19:06] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device "unknown" <sip:[email protected]>;tag=Ra0DFDKggt [2012-05-30 01:19:08] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device "unknown" <sip:[email protected]>;tag=rR7q7aTHEz [2012-05-30 01:19:10] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device "unknown" <sip:[email protected]>;tag=VHUMtOpIvU [2012-05-30 01:19:12] NOTICE[5578] chan_sip.c: Sending fake auth rejection for device "unknown" <sip:[email protected]>;tag=JxZUzBnPMW I use Asterisk for an automated phone system. The only thing it does is receives incoming calls and executes a Perl script. No outgoing calls, no incoming calls to an actual phone, no phones registered with Asterisk. It seems like there should be an easy way to block all unauthorized registration attempts, but I have struggled with this for a long time. It seems like there should be a more effective way to prevent these attempts from even getting far enough to reach my Asterisk logs. Some setting I could turn on/off that doesn't allow registration attempts at all or something. Is there any way to do this? Also, am I correct in assuming that the "Registration from ..." messages are likely people attempting to get access to my Asterisk server (probably to make calls on my account)? And what's the difference between those messages and the "Sending fake auth rejection ..." messages? Further detail: I know that the "Registration from ..." lines are intruders attempting to get access to my Asterisk server. With Fail2Ban set up, these IPs are banned after 5 attempts (for some reason, one got 6 attempts, but w/e). But I have no idea what the "Sending fake auth rejection ..." messages mean or how to stop these potential intrusion attempts. As far as I can tell, they have never been successful (haven't seen any weird charges on my bills or anything). Here's what I have done: Set up hardware firewall rules as shown below. Here, xx.xx.xx.xx is the IP address of the server, yy.yy.yy.yy is the IP address of our facility, and aa.aa.aa.aa, bb.bb.bb.bb, and cc.cc.cc.cc are the IP addresses that our VoIP provider uses. Theoretically, ports 10000-20000 should only be accessible by those three IPs.+-------+-----------------------------+----------+-----------+--------+-----------------------------+------------------+ | Order | Source Ip | Protocol | Direction | Action | Destination Ip | Destination Port | +-------+-----------------------------+----------+-----------+--------+-----------------------------+------------------+ | 1 | cc.cc.cc.cc/255.255.255.255 | udp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 10000-20000 | | 2 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 80 | | 3 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 2749 | | 4 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 443 | | 5 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 53 | | 6 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 1981 | | 7 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 1991 | | 8 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 2001 | | 9 | yy.yy.yy.yy/255.255.255.255 | udp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 137-138 | | 10 | yy.yy.yy.yy/255.255.255.255 | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 139 | | 11 | yy.yy.yy.yy/255.255.255.255 | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 445 | | 14 | aa.aa.aa.aa/255.255.255.255 | udp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 10000-20000 | | 17 | bb.bb.bb.bb/255.255.255.255 | udp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 10000-20000 | | 18 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 1971 | | 19 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 2739 | | 20 | any | tcp | inbound | permit | xx.xx.xx.xx/255.255.255.255 | 1023-1050 | | 21 | any | all | inbound | deny | any on server | 1-65535 | +-------+-----------------------------+----------+-----------+--------+-----------------------------+------------------+ Set up Fail2Ban. This is sort of working, but it's reactive instead of proactive, and doesn't seem to be blocking everything (like the "Sending fake auth rejection ..." messages). Set up rules in sip.conf to deny all except for my VoIP provider. Here is my sip.conf with almost all commented lines removed (to save space). Notice at the bottom is my attempt to deny all except for my VoIP provider:[general] context=default allowguest=no allowoverlap=no bindport=5060 bindaddr=0.0.0.0 srvlookup=yes disallow=all allow=g726 allow=ulaw allow=alaw allow=g726aal2 allow=adpcm allow=slin allow=lpc10 allow=speex allow=g726 insecure=invite alwaysauthreject=yes ;registertimeout=20 registerattempts=0 register = user:pass:[email protected]:5060/700 [mysipprovider] type=peer username=user fromuser=user secret=pass host=sip.mysipprovider.com fromdomain=sip.mysipprovider.com nat=no ;canreinvite=yes qualify=yes context=inbound-mysipprovider disallow=all allow=ulaw allow=alaw allow=gsm insecure=port,invite deny=0.0.0.0/0.0.0.0 permit=aa.aa.aa.aa/255.255.255.255 permit=bb.bb.bb.bb/255.255.255.255 permit=cc.cc.cc.cc/255.255.255.255
