DNS/DHCP nightmare with my network - Spiceworks - Page 2. JohnLF wrote:Wow lots of good advice here guys, thanks a lot.
I am heading towards one of the DCs being at fault. There is no pattern to the issue, the at-fault machines can be on any of the physical switches and getting an IP address from any of the DHCP servers. To cap it all, I have even seen the issue today on a couple of PCs where I assigned static IP addresses. Other PCs continue to work absolutely fine (my own included which is DHCP-assigned) I ran DCDIAG and one of the servers reported it wasn't authorised to replicate as it was a workstation not a server, even though replication appeared to be running fine and no other issues where being reported on it.
No errors on any of the switches either btw. A DC can replicate fine and still be broken. it just means it is a broken server with correctly functioning replication. you definitely need to demote the DC you think may be bad. Eye P.A.: Visual Packet Analysis. Go into detail with the Packets Tab In Eye P.A.’s Packets Tab, you’ll find a table that breaks down the packet traffic in your capture as it happened.
Being able to see the RSSI, Data Rate, and other specific packet-level details provides even more insight into the cause of a WLAN’s problems. Just like with the treepies, the packets table will update to reflect whatever filters and timespan you’ve set. You can also customize the columns to only show what you’re interested in. iBwave Wi-Fi Mobile.
A cloud-connected mobile app that makes it radically simpler to survey, design, validate and share your Wi-Fi network projects. iBwave Wi-Fi® Mobile is part of the iBwave Wi-Fi product suite, focused on helping you design and deliver great Wi-Fi networks in less time.
With seamless cloud connectivity between the mobile app and the desktop solution, you can access your Wi-Fi projects from anywhere, anytime. Take iBwave Wi-Fi® Mobile to complete your site survey and a preliminary design on-site – and then send it to the cloud and finishing working on it at your desk with iBwave Wi-Fi and its advanced 3D modelling capabilities. Note: iBwave Wi-Fi desktop will be launching in March. Stay tuned to hear more! Assess the network’s performance with active and passive surveys. See the network’s throughput with an active survey.

Wireshark 802.11 Display Filter Field Reference. OSX : inSSIDer. Scan the Wi-Fi networks around you and track their signal strength over time. inSSIDer scans all the Wi-Fi networks within the reach of your computer’s wireless card, tracks their signal strength over time, and determines their security settings.
Track open or secure wireless networks. Determine the best channel for your own wireless network. DOWNLOAD Use the Networks Table to view all nearby access points and their details. See Received Signal Strength, Security, Channel, Hardware Vendor, Max Rate, Network Type, and MAC Address for each access point. Use the Time Graph to view the strength of nearby access points. Click on any network listed in the table and the associated time graph line below will become bold, helping you identify a single network amongst many. WiFi Pineapple Mark V Standard – HakShop. The WiFi Pineapple is a unique device developed by Hak5 for the purpose of WiFi auditing and penetration testing.
Since 2008 the WiFi Pineapple has grown to encompass the best rogue access point features, unique purpose-built hardware, intuitive web interfaces, versatile deployment options, powerful software and hardware development aids, a modular application ecosystem and a growing community of passionate penetration testers. Robust The WiFi Pineapple is the only hardware with dual integrated radios custom built for advanced wireless attacks. The Mark V generation is based on the formidable Atheros AR9331 system on a chip (SoC), which includes a 400 MHz MIPS processor, 16 MB ROM and 64 MB RAM. Onboard is the infamous Realtek RTL8187 radio with monitor and injection capabilities, a Micro SD memory expansion port, a bank of configurable auto-attack mode switches, a USB 2.0 host port and 10/100 Ethernet port. Simple Intelligent Integrated Effective Reconnaissance Visualize WiFi landscape. Open Source Captive Portal Access Controller and RADIUS Software.

While tools to measure network performance. Iperf was orginally developed by NLANR/DAST as a modern alternative for measuring TCP and UDP bandwidth performance. Iperf is a tool to measure maximum TCP bandwidth, allowing the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss. Iperf features TCP Measure bandwidth Report MSS/MTU size and observed read sizes. AirMagnet Archived Webinars. Archived Webinars Surveys shouldn't just be for pre-deployment any longer.
This webinar covers how to use AirMagnet's SurveyPro to make sure your Wireless LAN design meets or exceeds the initial design parameters. You wouldn't turn over a cable install without validating your cable plant - so don't turn over a Wireless LAN without first 'proving' it meets your design goals. We'll cover what some industry standard goals are for a variety of WLAN types - and how you can measure, validate, and report these for your Wireless networks. Presented by Keith Parsons - who's taught thousands of people to maximize the use of the AirMagnet SurveyPro software. »Download. WiGLE - WIFI Database. OSX :EaKiu. Wireless Technologies.

Correspondance entre puissance en Watts (W) et puissance en décibels "milliwatts" (dBm): (dBm= 10*log10(P/ 0.001)) Les cartes Orinocco ont une puissance d'émission de 30mW Les cartes Proxim (Home RF) ont une puissance d'émission de 100mW Perte dans un cable coaxial à 2.45 GHz Valeurs typiques pour quelques cables coaxiaux courants: RG 58 (trés courant, utilisé pour les réseaux Ethernet par exemple): 1 dB par mètre. Antenne Le gain d'antenne est normalement donné en décibels isotropiques [dBi]. Antenne parabolique: Le réflecteur parabolique est indépendant de la fréquence, il affecte seulement le gain de l'antenne.
