View 5 Replies View Related3 PCs With Crossover Cables?
Jun 26, 2011I'm currently training at a PC store.Me and this other guy are trying to figure out some networking.So far we've file shared 2 PCs with 1 crossover cable.Now we're trying to figure out how to do this with 3 PCs and NO hub, switch, router, etc.I have my theory and he has his.
His theory: One of the computers need an ethernet card so 2 crossover cables can be plugged into it.(The MOBOs only have one port to plug in Cat5s)
My theory: Cut 2 crossover cables in half. And put the three ends together so the wires are touching each other, then tape it. For example green to green to green, orange to orange to orange, etc.Here's an example picture: Now I know my theory would work with audio but me co-trainee isn't so sure if it will work with networking.
How To Identify Optical Cables
Dec 19, 2012I've seen where the micron is printed on a fiber strand, and that you can identify the connector type, but how do identify the difference between a 50 micron OM4 MMF, a 50 micron OM3 MMF, and a 50 micron OM2 MMF?

View 1 Replies View RelatedTwo MDI-X Devices Using Only Straight Through Cables?
Aug 31, 2011I purchased a D-Link switch that supports MDI-X so I should be able to use only straight through cables according to the manual. My Router (Wrt54gs) also supports MDI-X, yet when I plug a straight through cable from port 4 on router to port 1 on the switch -> then a straight through from port 2 on the switch to my computer, I don't get an IP address.If I connect a crossover cable from the router to port 1 on D link switch -> then straight through from port 2 to computer, it works just fine.I am going to purchase an extra crossover cable to use for this but I'm really curious as to why it wont work this way? DES-1105 is the model of the switch. "THE DES-1105 CAN BE CONNECTED TO ANOTHER SWITCH OR OTHER DEVICES (ROUTERS BRIDGES ETC) VIA A TWO-PAIR CATEGORY 3,4,5 UTP/STP STRAIGHT THROUGH OR CROSSOVER CABLE."

May 16, 2011I had one straight through cable connecting one switch and a pc in my office. The cable is approx 90 metres in length. The cable has been cut in between by rat. Now can I join those 2 cables by a coupler, if so will it increase latency, what type of crimping is required, straight through or cross cables. I think 2 cross cables connected by a coupler becomes straight.

ISP Blocks Default Gateway Address

View 1 Replies View RelatedEdimax Blocks All Incoming Connections?
Nov 5, 2011i have with my Edimax router. I could not make any progress with Edimax personnel in Taipei.
If i connect my vista box directly w/o the router, i can see that port 21 (Filezilla) is open, using WhatsMyIP.org | Port Scanners/Sniffers
When I insert the Edimax br6215srg router, the port is in timeout as reported by aforementioned site (guess the port scanner gets no synack nor reset back to the syn it sends)
The router is set to "disable firewall" or to "enable firewall and DMZ enabled" with as client's ip the one that is configured in the router's dhcp table for the vista box. The NAT module is set to forward port 21 to the same ip. ipconfig confirms that i do get the ip programmed in the router's dhcp table.
I do not want to believe that this edimax box is unable to forward connections!
D-Link DIR-615 :: Access Control Blocks Too Much
Oct 24, 2012I have tried to setup access control by setting up a policy that restricts certain MAC addresses during a period during the day from certain websites. I set up the website filter and a schedule and selected them for the policy. Instead of blocking just the websites on the filter list during the time setup in the schedule, it blocks all websites all the time.I made sure that I setup the policy to 'block some access' NOT 'block all access'.The only thing that seems to work is that only the computers with the MAC address selected are effected.
View 3 Replies View RelatedD-Link DIR-655 :: Blocks DNLA To / From PS3 And Plex
Dec 28, 2012I have a simple set-up: a DIR-655 with 2 devices plugged in to it. The Plex Media Server runs on Ubuntu Linux and acts as the DLNA server to a PS3 DLNA client. Both are hard-wired with ethernet cables to the DIR-655. In this set up the PS3 has trouble discovering the PLEX server via DLNA. A 'search for DLNA devices' on the PS3 fails to return the PLEX. Eventually, after some strange time interval ranging from 2-30 minutes, the PLEX server will show up on the PS3's list.
I attached a simple ethernet switch to the DIR-655 and then attached the PS3 and Plex/linux server to it. The PS3 now finds the Plex DLNA server INSTANTLY ... without even having to scan for servers.
It appears that the DIR-655 is trying to be 'useful' in some way by filtering some sort of traffic; multicast/igmp I assume. There don't appear to be any settings in the GUI to alter the Multicast/IGMP/DLNA/UPnP behavior in the LAN ... other then "turn UPnP on."
Note that this is hardware B1 and firmware 2.00NA.

View 1 Replies View RelatedCisco VPN :: ASA 5550 Blocks Traffic For Some IP
May 14, 2013In our company we use ASA 5550 as a VPN server (failover pair, FW 8.2(5)). Long time we used Cisco VPN client (easyVPN) only and some time ago we started to use L2TP/IPsec VPN from Windows clients.From this time we can see strange behavior. Some ip addreses (we use ipv4 only) from local VPN ip pool are getting unusable for clients. When client gets this ip address the traffic from client to intranet is ok but the traffic from intranet to the client is blocked. This behavior affect both L2TP/IPsec and easyVPN clients with this ip address.The packet trace shows that the traffic will be blocked because implicit deny ACL but ACL for the connected user is created:
Phase: 10
Type: ACCESS-LIST
Subtype: vpn-user
Result: DROP
Config:
Additional Information:
[code].....
We use RADIUS for authentication and ACL. Failover to the standby ASA solves the problem but this terminates all L2TP/IPsec VPN connections.We use Cisco Anyconnect VPN too and when Anyconnect client gets this „strange“ ip address he can communicate normally without problems. It looks like that this problem is related to IPsec. how to discover why ASA uses -implicit deny- instead of user ACL?
Cisco VPN :: 5510 L2L IPSec VPN Blocks SQL
May 17, 2012I have an ASA 5510 running 8.4(2) which has a site to site IPSec VPN to a 3rd party who run some form of Checkpoint. The VPN establishes and allows access to a server in our DMZ on all ports that we have tested (so far HTTP, SSL, RDP, FTP) except for SQL which doesn't even seem to reach the server. I've got Wireshark running on the DMZ server and if the 3rd party initiates a TCP conversation from their server on any of the working ports to the server I see all of the expected packets arrive with the correct IPs etc (no NAT takes place across the VPN) but when an ODBC client attempts to query the SQL server on our DMZ box the packets do not arrive at the server. What I can see is the RX byte count on the VPN increasing each time the query is run but definitely no SQL arriving at the server.
Also if I revert the ASA back to the old PIX it has replaced with the same VPN config but on version 7.x then it works just fine.
Home Network :: Run A Longer RG6 Or CAT6 Cables
Aug 19, 2012There are 2 locations to choose from. One location requires me to run longer CAT6 cables. 7 of them. The other location requires me to run a longer RG6 cable. (the CAT6 runs would then be about the shortest they could get)So, I guess I need to know which can handle running parallel with power cables better, 25feet of RG6 or CAT6?The parallel with power cable is only for about 6-8 feet, but that's already more than it should be for CAT6.
View 4 Replies View RelatedRange Extending - Cables And Speed Limits?
Jun 3, 2011I'm an electrical engineer by trade, and fairly inept at networking. That being said, I am looking to extend the maximum range of my networking equipment. I have a job which requires around 500' between switches, and am trying to find a clever way to bridge the gap. The span is direct-burial cat5e, and has very low bandwidth requirements. I know you can buy off-the-shelf range extenders, but they are expensive, so I thought maybe I could avoid it.
1. It my understanding that the lower speed protocols (10 Mbps rather that 100, 1000) have a longer maximum operating length, because they utilize a lower frequency and consequently see a lower impedance. If so, are there network switches that I can force to use the lower baseband frequencies?
2. Should I bother trying to find a cable with the lowest characteristic impedance (or will they all be similar)? Cat 5e is pretty good, yes?
3. Should I do half or full-duplex; is this something I can control as well?
4. What network switches are cheap and allow this type of configurability?
5. If I attach other switches to the ends of this 500' ethernet bridge with auto-negotiating feature, will there be any conflicts or they will all get along?

D-Link DIR-655 :: Connect LAN Cables Between Modem / DIR / Stationary PC?
Jan 4, 2011I bought a DIR-655 last week and have a very odd problem: have set up the DIR router after my Modem/Router Netgear DG834 when i connect a laptop with LAN cable to one of the LAN ports on the DIR i can access internet without any problem.When i search wireless network from my laptop the DIR turns up and have excellent reception(4-5bars).
This works fine when i start for ex. google, but then after clicking on a link or trying to access any other webadress, the internet disconnects?? (i still have excellent reception between the router and laptop.)It also seems that the internet connection is reestablished automatically after 1-2 min, but disconnects again after a few minutes. I have the same issue with WII, the WII console finds DIR but when I'm trying to update the firmware in the WII console the connection stop working.
One more Q: when i connect LAN cable from modem to DIR i get no internet access, should it be that way? How u are suppose to connect LAN cabels between modem/DIR/stationary PC?

The new block is a /29 range and I would need to use just two of those IP addresses. Here is the situation I am facing.A company we partnered with wants to set up a VPN, they will send us 2 Cisco 861s to put behind our ASA. Is it possible to assign these 861's with public IPs from the block that we are not currently using? (the /29 range)? I know that it might require an upgrade to the Security Plus.
