I'm a college professor and was assigned a new course called Distributed Operating Systems. I'ts new material for me. And in research for class I have found that several machines can be connected together to build a bigger computer like a supercomputer. How could I connect several PC's and make them work together like parallel computing, o something likea super computer?

View 1 Replies View RelatedI am trying to put a wireless router behind another router. I have DHCP on the wireless router disabled and connected wireless router LAN port to wired router LAN port. The wired ports on the wireless router work fine. The wireless signal strength is good and shows a good connection. But wireless connectivity to the internet is poor. Ping to the main router shows most packets are lost. I have assigned the wireless router an address outside the DHCP range but in the same group. Main router is 192.168.15.1, wireless is 192.168.15.2, DHCP range is 192.168.15.100 to 192.168.15.130. I though the router might be bad as it is an older one so I got a new one - same issue.Update - found the problem. The wireless on the old router was still connected and running. Had some trouble getting wireless turned off for it. First speedtest.net run on new wireless showed low download speed (0.35 Mbps) but later showed same as wired (1.3Mbps). Not sure why the first test was so low as I have tested several times and now get the higher number. The old router (DI-524) even seems to display its web interface slowly although the wired ports still seem to work ok at least LAN to LAN.

View 2 Replies View RelatedOur ISP will give us a single drop with two public IP blocks - one primary, one secondary. I would like to configure and run 2 firewalls:
firewallA will have a public ip from primary interface
firewallB will have a public ip from secondary interface
I'm very new to networking, and trying to find out how I can do it. We have a cisco 2901 router.
I'm considering
connect the drop to the WAN side of a router (2901)
configure both the primary and secondary interfaces on the router
configure the router in bridge mode
assign the public ips to the firewalls and connect them to the LAN interfaces of the router
(I know I can use 1 firewall and configure both interfaces on it without the router, but I would like to know if the above setup will work).
Obviously you do not want your cat6 lines running too close to your power lines especially when in parallel. The question though is how close can it be without causing interference?In my situation the wall I want to connect my main router to has a power outlet in the middle of it which honestly is where I would have preferred my network ports. Will I be OK if I run my cat6 in the wall channel directly next to the channel that contains the power line? It would be a standard U.S. interior wall residential power line. I should be able to get from 12 to 24 inches of distance between my cat6 and power line while still keeping my network outlet in a semi-central location.
View 1 Replies View RelatedI'm trying to estimate the potential throughput I will be able to achieve on a network we are building. The core ring of the network will be composed of ruggedized industrial ethernet Cisco IE 3000-8TC-E, possibly each equipped with a IE 3000-8TM expansion module. We will be using 1000BASE-BX SFPs on the IE-3000s to form a 1Gbps backbone on a single fiber. The issue is that I want to establish branch connections out from each IE-3000 node on my ring to routers which can support 1Gbps, but I have no 1Gbps downlink ports available on my IE-3000's. Therefore, I was thinking of paralleling as many 100BASE-TX copper links from the IE-3000 to my routers, so as to emulate a 1Gbps link and achieve maximum throughput. Both sides will have 16x 100BASE-TX connections available... but what is the maximum number I can parallel together and what achievable real throughput can I assume given the innefficieny of paralleling multiple connections?
View 3 Replies View RelatedCurrently my setup works fine except that I need another ethernet port.I have a E4200V2 with a HP laserjet 4000N printer connected via JetDirect ethernet and I am able to print with any of my devices.However, because I have need of another ethernet port, I am wondering if anybody has tried using a parallel to usb cable? The parallel side of the cable being connect to the printer and the usb side to the router.
Or if I really want that port made available, will I have to get some type of external print server?
I know that HP makes a JetDirect Card with a USB port, however, I don't want to spend the $80 on ebay to get a used one if a $10 new cable will work.
I am using a cable company called Cox.net for the internet. The cable modem is Motorola brand.Sometimes, the modem got disconnected due to outage in my area. But after Cox fixed the outage, I have to reset the modem. The problem is I do not know when the outage is fixed. Sometimes, I reset the modem and call cox all day long. Is there a modem which can reset itself after there is the internet signal?The second question is my desktop pc, which connected to the wireless router through a cable, sometimes displays a error page in IE8 (Internet Explorer). At the same time, the laptops using wireless can view IE8 pages.I think what happened is there is a internet signal outage in my house but the laptops got re-connected to the internet automatically and the desktop did not re-connect. Sometimes, I can ping a website on the desktop but I cannot see the pages in IE. Re-open IE does not fix the problem. The solution is to re-boot the pc. Is there a network card or software I can use to re-connect to the web after the internet signal becomes available? My pc's mother board has the network device to plug in the cable. The brand is Gigabyte.
