  • Detecting man-in-the-middle attacks?

    - by Ilari Kajaste
    There seem to be many possible ways to create man-in-the-middle attacks on public access points, by stealing the access point's local IP address with ARP spoofing. The possible attacks range from forging password request fields, to changing HTTPS connections to HTTP, and even the recently discovered possibilit of injecting malicious headers in the beginning of secure TLS connections. However, it seems to be claimed that these attacks are not very common. It would be interesting to see for myself. What ways are there to detect if such an attack is being attempted by someone on the network? I guess getting served a plain HTTP login page would be an obvious clue, and of course you could run Wireshark and keep reading all the interesting ARP traffic... But an automated solution would be a tiny bit more handy. Something that analyzes stuff on the background and alerts if an attack is detected on the network. It would be interesting to see for myself if these attack are actually going on somewhere.

  • Proxification rulte for System process

    - by kseen
    I'm trying to configure Microsoft Visual Studio 2010 remote debugging and ran into issue: while connecting to remote computer running MSVSMON, client computer sends SYN request for connection. It makes it under the System process (as I see it in TCPView). As every network apps should be configured to use proxy in our network, I'm trying to add devenv.exe to proxification rules to make its traffic goes thru LAN's proxy server. It doesn't help. So my question is how can I make that low-level-system traffic will go through local area network proxy server?

  • BUILD 2013 Session&ndash;Testing Your C# Base Windows Store Apps

    - by Tim Murphy
    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/27/build-2013-sessionndashtesting-your-c-base-windows-store-apps.aspx Testing an application is not what most people consider fun and the number of situation that need to be tested seems to grow exponentially when building mobile apps.  That is why I found the topic of this session interesting.  When I found out that the speaker, Francis Cheung, was from the Patterns and Practices group I knew I was in the right place.  I have admired that team since I first met Ron Jacobs around 2001.  So what did Francis have to offer? He started off in a rather confusing who’s on first fashion.  It seems that one of his tester was originally supposed to give the talk, but then it was decided that it would be better to have someone who does development present a testing topic.  This didn’t hinder the content of the talk in the least.  He broke the process down in a logical manner that would be straight forward to understand if not implement. Francis hit the main areas we usually think of such as tombstoning, network connectivity and asynchronous code, but he approached them with tools they we may not have thought of until now.  He relied heavily on Fiddler to intercept and change the behavior of network requests. Then there are the areas you might not normal think to check.  This includes localization, accessibility and updating client code to a new version.  These are important aspects of your app that can severely impact how customers feel about your app.  Take the time to view this session and get a new appreciation for testing and where it fits in your development lifecycle. del.icio.us Tags: BUILD 2013,Testing,C#,Windows Store Apps,Fiddler

  • KVM CLI install for CentOS 6.3 defaults to Minimal Install

    - by i.h4d35
    So I now I've installed KVM (and its associated tools and packages- libvirt, VMM etc.). On the GUI (i.e using the VMM), installation works as its supposed to. However, when I try to create a VM using the command line interface, the OS (I am working with CentOS 6.3) defaults to a Minimal Install instead of giving me options to choose from at the time of installation. I am trying to install using the following command: virt-install \ --connect qemu:///system \ --virt-type kvm --name testVM2 \ --ram 512 --disk path=/var/lib/libvirt/images/testVM2.img,size=8 --vnc \ --cdrom /media/db18de8e-0853-49fb-80de-5c794d58a46f/CentOS-6.3- x86_64-bin-DVD1.iso \ --network network=default Specifying the OS-type or the OS-variant parameters doesn't make a difference. Is there something that I am missing out on or some other parameter that I must specify? Thanks in advance.

  • Bridging VirtualBox over OpenVPN TAC adapter on Windows

    - by Sean Edwards
    I'm trying to configure a virtual machine (VirtualBox guest running Backtrack 4) with a bridged adapter over a VPN connection. The VPN is is hosted by the cybersecurity club at my university, and connects to a sandboxed LAN designed for penetration testing against various servers that the club has built. My host (Windows 7 Ultimate) connects to the VPN fine and is assigned an IP through DHCP, but for some reason the VM can't do the same thing, and I'm not sure why. It's like OpenVPN is filtering out packets from the MAC address it doesn't recognize. I want the virtual machine to bridge over the VPN connection, because our IT office has very strict policies about what you can and can't do on the network. I want to be able to run active attacks (ARP spoofing, nmap, Nessus scans) in the sandbox environment without risking the traffic accidentally going over the university network and getting my internet access revoked. Bridging over the VPN connection and running all attacks from inside the VM would solve that problem. Any idea why the host can use this interface, but the VM can't?

  • Improved Performance on PeopleSoft Combined Benchmark using SPARC T4-4

    - by Brian
    Oracle's SPARC T4-4 server running Oracle's PeopleSoft HCM 9.1 combined online and batch benchmark achieved a world record 18,000 concurrent users experiencing subsecond response time while executing a PeopleSoft Payroll batch job of 500,000 employees in 32.4 minutes. This result was obtained with a SPARC T4-4 server running Oracle Database 11g Release 2, a SPARC T4-4 server running PeopleSoft HCM 9.1 application server and a SPARC T4-2 server running Oracle WebLogic Server in the web tier. The SPARC T4-4 server running the application tier used Oracle Solaris Zones which provide a flexible, scalable and manageable virtualization environment. The average CPU utilization on the SPARC T4-2 server in the web tier was 17%, on the SPARC T4-4 server in the application tier it was 59%, and on the SPARC T4-4 server in the database tier was 47% (online and batch) leaving significant headroom for additional processing across the three tiers. The SPARC T4-4 server used for the database tier hosted Oracle Database 11g Release 2 using Oracle Automatic Storage Management (ASM) for database files management with I/O performance equivalent to raw devices. Performance Landscape Results are presented for the PeopleSoft HRMS Self-Service and Payroll combined benchmark. The new result with 128 streams shows significant improvement in the payroll batch processing time with little impact on the self-service component response time. PeopleSoft HRMS Self-Service and Payroll Benchmark Systems Users Ave Response Search (sec) Ave Response Save (sec) Batch Time (min) Streams SPARC T4-2 (web) SPARC T4-4 (app) SPARC T4-4 (db) 18,000 0.988 0.539 32.4 128 SPARC T4-2 (web) SPARC T4-4 (app) SPARC T4-4 (db) 18,000 0.944 0.503 43.3 64 The following results are for the PeopleSoft HRMS Self-Service benchmark that was previous run.

The PeopleSoft HRSS benchmark kit is a Oracle standard benchmark kit run by all platform vendors to measure the performance. It's an OLTP benchmark where DB SQLs are moderately complex. The results are certified by Oracle and a white paper is published. PeopleSoft HR SS defines a business transaction as a series of HTML pages that guide a user through a particular scenario. Users are defined as corporate Employees, Managers and HR administrators. The benchmark consist of 14 scenarios which emulate users performing typical HCM transactions such as viewing paycheck, promoting and hiring employees, updating employee profile and other typical HCM application transactions. All these transactions are well-defined in the PeopleSoft HR Self-Service 9.1 benchmark kit. This benchmark metric is the weighted average response search/save time for all the transactions. The PeopleSoft 9.1 Payroll (North America) benchmark demonstrates system performance for a range of processing volumes in a specific configuration. This workload represents large batch runs typical of a ERP environment during a mass update. The benchmark measures five application business process run times for a database representing large organization. They are Paysheet Creation, Payroll Calculation, Payroll Confirmation, Print Advice forms, and Create Direct Deposit File. The benchmark metric is the cumulative elapsed time taken to complete the Paysheet Creation, Payroll Calculation and Payroll Confirmation business application processes. The benchmark metrics are taken for each respective benchmark while running simultaneously on the same database back-end. Specifically, the payroll batch processes are started when the online workload reaches steady state (the maximum number of online users) and overlap with online transactions for the duration of the steady state. Key Points and Best Practices Two PeopleSoft Domain sets with 200 application servers each on a SPARC T4-4 server were hosted in 2 separate Oracle Solaris Zones to demonstrate consolidation of multiple application servers, ease of administration and performance tuning. Each Oracle Solaris Zone was bound to a separate processor set, each containing 15 cores (total 120 threads). The default set (1 core from first and third processor socket, total 16 threads) was used for network and disk interrupt handling. This was done to improve performance by reducing memory access latency by using the physical memory closest to the processors and offload I/O interrupt handling to default set threads, freeing up cpu resources for Application Servers threads and balancing application workload across 240 threads. A total of 128 PeopleSoft streams server processes where used on the database node to complete payroll batch job of 500,000 employees in 32.4 minutes.

  • PXE in an 802.1X environment

    - by newmanth
    My organization is about to implement 802.1X on our enterprise, but we currently use PXE-based OS deployment sequences in SCCM. I'm looking for a way to continue using PXE in an 802.1X environment. Our infrastructure uses Cisco network gear running at 12.2 (or newer). We are an all Windows network and all clients support 802.1X. All new workstations have Intel AMT available (but not factory configured). In a worst case scenario, we'll use a guest vlan for OSD, but I'd rather have the OSD occur in an authenticated session. I've seen white papers that describe using AMT to act as a supplicant for PXE boot, but can't find any implementation details...

  • CentOS Failover Cluster - SIOCADDRT: No such process (when adding a loopback)

    - by Steve Rolfe
    I'm trying to configure two web servers for a load balancing server. The load balancing aspect works fine (it sees both server, kills 'em if it needs to, and seems to direct traffic fine). The only issue is with the servers looping: /etc/sysconfig/network-scripts/ifcfg-lo:0 DEVICE=lo:0 IPADDR=<Virtual IP> NETMASK=255.255.255.255 ONBOOT=yes NAME=loopback Everytime I try a "service network restart" I get a SIOCADDRT: No such process when loading the loopback interface. Anyone have an idea what's causing this?

  • Can I setup a link SQL server connection between servers on different networks?

    - by Glenn Slaven
    We have a production SQL server hosted offsite at a hosting company, and we have a staging environment within our own network. We want to be able to setup a SQL job that copies content from a table on the staging server to prod on a regular basis, and I think we need to setup a linked server connection to do this. What do I need to get the hosting company to do to allow us to set this up? We have RDP access to the production servers, I just need to know what network and security configurations need to happen from the hosting company's perspective so I can ask them to do it.

  • What are some of the best wireless routers for a price-conscious home power-user?

    - by Alain
    I'm extremely dissatisfied with the 'popular' choice for routers in homes and small offices. They are expensive (upwards of 60$), lack a great deal of useful configuration options, and seem to need to be restarted quite often. (Linksys comes to mind). I've been on the market for a good router lately, and slowly collecting a set of requirements I feel good routers should meet. Maximum number of TCP/IP connections. - This isn't something I see any routers advertise, but in terms of supporting torrent applications, I've been screwed by routers that support less than 20 here. From what I understand a fairly standard number is 200, but there are not so expensive routers that support thousands. Router configuration menu - Most have standard menu's that let you set up basic things like your wireless network encryption settings, uPnP, and maybe even DMZ (demilitarized zones). An absolute requirement for me, however, are routers with good enough firmware to support: Explicit Port forwarding Assigning static local ips to specific mac addresses, or at least Port forwarding by MAC address Port, IP and MAC filtering Dynamic DNS service for home users who want to set up a server but have a dynamic IP Traffic shaping (ideally) - giving priority to packets from certain machines or over certain ports. Strong wireless signal - If getting a reliable signal requires me to be so close to the router that I can connect an Ethernet cable, it's not good enough. As many Ethernet ports as possible. - Because I want to be able to switch from console gaming to PC gaming without visiting my router. So far, the best thing I've stumbled upon (in the bargain bin at staples) was a 20$ retail plus router. It was meant to be the cheapest alternative until I could find something better to purchase online, but I was actually blown away by the firmware capabilities. It supports defining reserved bandwidth for certain network traffic, dynamic DNS, reserving local IPs for specific MAC addresses, etc. At 2 am when my roommate is killing our Internet with their torrents, I can limit their bandwidth without outright blacklisting them. I have, however, met serious limitations when it comes to network traffic between local machines. It claims a 300Mbps connection, but I have trouble streaming videos from my PC to my console or other laptops wirelessly. It has a meltdown and needs to be reset once in a while (no more than a couple times a month), and it's got a 200 connection limit. There 4 Ethernet ports in the back but I'm pretty sure the first doesn't work. So some great answers to this question would be: Any metrics you use to compare routers, and requirements you have for new candidates. The best routers you've found for supporting home servers, file management systems, high volume torrent traffic, good price/feature ratio, etc. Good configuration advice (aside from 'use Ethernet whenever possible') Thanks for your feedback and experiences!

  • Ideas for campus Internet Login mechanism?

    - by miCRoSCoPiCeaRthLinG
    Hello, I work at this university and I'm seeking an effective solution for an internet login mechanism. We have a leased-link at our campus, which is shared by both staff & students. All systems (desktops + laptops + handhelds) connect to the internal network via wifi and can then get onto the net. However, a local govt. regulation requires us to keep track of individual internet usage and hence we need a solution (pref. free / opensource) that'll enable us to implement some sort of an authentication mechanism once a user hooks onto the network. One requirement is that the software should be able to authenticate either against LDAP or some other custom user database (MySQL based) or both. Can anyone suggest any such software or mechanism? Most of our servers are Linux based... so something that runs off such a platform will be good. Thanks, m^e

  • Netgear Wireless-n 150 wrn1000v2

    - by Jordan
    I'm not sure if this is the place to ask this question, move it if it's not. I'm trying to fix a wireless network. It only connects to a few devices and when it does work the connection is spotty. The router is a netgear wireless-n 150 wrn1000v2. Connecting to the router isn't a big problem, but connecting to the internet via WiFi is. I can't upgrade the firmware becuase it is from Comcast and it seems as though they only allow their versions of the firmware. I've monitored the network with wireshark and I see that the devices that are having trouble connecting are constantly asking "who is 192.168.1.1 tell 192.168.1.x" where x is the ip for the device. 192.168.1.1 is the router. This is from running wireshark on the wireless device. What does this mean. At this point I feel like buying a new router is the only option.

  • Strongswan and OpenVPN together

    - by cmorgia
    I have an host in Amazon EC2 which is configured with an OpenVPN Access Server. The only client to this server is acting as a gateway from a private network. I installed StrongSWAN 5 on the same host to allow windows 7 and iOS clients to connect using IPSEC. Both services works but what I cannot figure out is how to configure StrongSWAN to consider the OpenVPN tunnel endpoint as the only gateway available to clients. Basically I want all the traffic that comes from IPSEC clients to be entirely forwarded to the OpenVPN tunnel. The remote OpenVPN client that is exposing the private network has forwarding enabled and appropriate masquerading configured. The only missing point is to have the OpenVPN tunnel as the gateway for IPsEC clients
