  1. If the video stops always in the same point and if you jump over that point it continues to play means it is probably not network related but a codec issue (the decoder used in kaffeine is too old and the video have a new feature added in a later revision, for example). Sometimes you can find problems with buffering when using a "kde player" in gnome or a "gnome player" in kde. It was worse in the past. IIRC it's because the underlying libraries that access network resources can't pipe with the ones that decode the data (but I am not sure, I read the explanation a few years ago). You can try another player or mount the shared folder on one local folder and play from there.
  2. You can know a lot of things about computers, how to make an über-PC with 4 GPU, overclocked with liquid nitrogen and for only a dime but have no clue how networks work. On the other side, you can be someone who can develop and code your own exploits or read wireshark logs like a newspaper and can't mount your own PC or know the differences between crossfire and SLI. In a sense, yes, they can be totally different things.
  3. I understand how forwarding, NAT and DDOS works and that's why I asked: If the request if TCP, it reaches the router, then it is forwarded to an IP:port where no program is active (no socket binded and listening there, maybe not even a host in that IP). If there is no one who can send a SYN/ACK packet therefore the connection is not stablished and packets are dropped or a destination unreachable ICMP is sent to the sender. If you forward a port to a dynamic IP or you assign dynamic IPs in the same range where your servers are, then security is not the only problem you have. Remember, always use manual/fixed IP when you forward ports (they can and will change with time) and never mix DHCP and manual ranges in the same network (or you will end with duplicate IPs). Anyways, I was asking if there was some kind of attack that can exploit an orphan port forwarding in a way similar to this (minutes 1 to 14): That's my point. I asked because of this affirmation:
  4. Does one of the blades touch anything?
  5. It the problem is the wifi itself (wifi card, interferences, etc), yes. If the problem is in the connection, the PC or the router, no.
  6. Uhmm... I have a two questions: - What difference makes having a forwarded port in DDOS? - Forwarding a port doest not "open" it. How can it be exploitable if there is nothing to listen there?

    Oh, I missed the K. Then... "I think you get your speed as it is intended since AFAIK you pay for 120 Kbps down and 15 up. "

  9. It is not about how you connect them physically, but how you configure them. A router, by definition, separates 2 or more networks. What you need to do is to configure one of them as a bridge.

    Wheel on a budget

    Don't get anything cheaper than the Driving force GT. The quality drop is big under that price point. You can try to find a second hand G25 or G27. My G25 is from 2007 and it is still going strong.
  11. I don't care if you call low-end, mainstream or just X, as long as they will offer VR level performance for 200-250 $ (dreaming)

    Wi-Fi issues

    can he ping the router from the pc?
  13. In fact it is just the opposite with the current output. Alkaline cells outperform NiMH batteries only if the discharge current is low. Here is an example of LOTS of comparisons between flashlights (most of them don't use AA, but the ones who do have both alkaline, and NiMH): http://www.flashlightreviews.ca/reviews.htm edit: I would use eneloops AND a good smart charger. Using timed chargers will torture and kill your batteries.
  14. Do not connect switches in cascade Learn how to set up and troubleshoot a DHCP server Labeling your cables is a good idea. Test them. Do your maths with the amount of power you will need (tip: it will be a lot) and how big the electrical cables need to be. Be prepared to find some ungrateful people who will complain for stupid things.
  15. MAC, not Mac https://en.wikipedia.org/wiki/MAC_address
  16. The most important thing you can control is how do you use the available connection. It does not matter having 1 Gbps at home if you saturate the line, for example using torrent or syncing a virtual drive over the internet. ...and use cable, not wifi

    3 SSIDs?

    Some routers have a "guest" network you (or your ISP if the router is theirs) can activate. To be sure if the SSID is yours, just unplug the router and check which names disappear from the list.
  18. I see the Define S as a R5 with no 5.25''' bays and moving the 3.5 HDD to the side (and reducing the amount of them to 3) to make room for liquid reservoirs. I have a R5. The rack zone is well insulated and even if you use a couple of HDD for big storage capacity the case will remain silent. OTOH, if your PSU, CPU or graphic card are noisy, you will hear them because of the back grill.
  19. A set of Zalman coolers. When I bought my Athlon XP back in the day the system was so loud I really had headaches when using my computer. Then I bought a CNPS6000-Cu, a passive heatsink for the graphic card and and another for the northbridge. Since I had a very silent PSU (made by fortron) and the quietest HDD ever (a 40 GB seagate) I went from headaches to "is that on?" even when CPU was 100%.
  20. I used this in the past, http://vb-audio.pagesperso-orange.fr/Cable/index.htm, which is the same but free.
  21. As long as your CPU is not too hot, it does not mind. I never saw a CPU wearing out with a stock cooler and 60ºC but a lot of them breaking when mounting an aftermarket one incorrectly or trying too much voltage when overclocking (yes, I know these forums are for the enthusiast, don't kill me). I think it is more important having the cooler dust-free and good airflow in and out the case if you are short on money.
  22. Is the wireless on in the laptop? Is there any wireless connection icon in the control panel? Does it show anything wireless related if you do "ipconfig" in a command prompt?
  23. A heater is the P4 is a Presshot
