  • Need to open links in new tab in ie8 !

    - by BHOdevelopper
    I have a sidebar (right sided iframe) and when i click on a link in it, it opens a new window in IE8, (in firefox it open a new tab). What do i need to do to open links in IE8 in a new tab. I already set the Tools-Internet Options-Settings- 'Always open pop-ups in a new tab' and 'A new tab in the current window' open in new tab but still doesn't work. My links are pretty simple, what am i missing ? exemple: text. Also some site are saying to register Regsvr32 actxprxy.dll to fix this problem, still doesn't work. And i want this to work with a simple click, no 'right-click-open in new tab' option. I also hope i won't get the 'can't change how ie8 works' answer. ;)

  • Why are people trying to connect to me network on TCP port 445?

    - by Solignis
    I was playing with my new syslog server and had my m0n0wall firewall logs forwarded as a test, I noticed a bunch of recent firewall log entries that say that it blocked other WAN IPs from my ISP (I checked) from connecting to me on TCP port 445.

  • how to pass traffic for port 80 not through openvpn?

    - by moti
    Is there a way to configure OpenVPN clients to route traffic for HTTP port 80 and HTTPS port 443 directly (i.e. not through the VPN), but through the regular default gateway the clients have. All other traffic should go through the VPN. My client is running OpenVPN on Windows and my current configuration looks like this: client dev tun proto tcp remote my-server-2 1194 resolv-retry infinite nobind persist-key persist-tun ca ../keys/ca.crt cert ../keys/client1.crt key ../keys/client1.key ns-cert-type server verb 3 route-metric 1 show-net-up dhcp-renew dhcp-release route-delay 0 120 hand-window 180 management localhost 13010 management-hold management-query-passwords management-forget-disconnect management-signal auth-user-pass

  • Full speed internal switch bandwidth but per-port set external bandwidth?

    - by garg
    I am in an environment where all the machines are behind a switch that I don't have access to. Each ethernet wall port has limited bandwidth depending on how much has been paid for each port. The problem is that some people have 10Mbps connections and some have 100Mbps connections and this causes problems with local intranet file transfers and operating system/software deployments. Operating systems can take hours to be deployed if the machine is on 10mbps. Do you know if it is possible with most switches to set a rule that would limit bandwidth coming in/going out to an extranet, but keep full bandwidth if the packets are destined to go to a local machine? For example, the internet might be limited to 10Mbps, but internal servers would get gigabit speeds? Thanks

  • Networking switch setup

    - by Crash893
    I have two 48 port gigabit netgear switches with 2 SFP ports each (i also have two Mini-GBIC copper transceiver modules) Is it best to set the ports up by using the built in ports (ie plug port 1 of switchB into port 48 of switchA and port1 of switchA into the router) or is there an advantage to using the mini-gbic? (lets call the sfp ports 49 and 50) router - port 49 on switchA, port 50 switchA - port 49 SwitchB

  • How do I connect to the serial console port os a Sunfire 280R?

    - by DrStalker
    We have a Sunfire 280R (old SPARC/Solaris server) that is refusing to come up after being relocated. We're trying to connect to the serial console port, but all we get is random gibberish on the screen. We've tried both connecting with a DB25DB9 adapter and using a DB-25-RJ45 adapter with a cisco RJ45-DB9 adapter to a windows laptop. We're configuring the laptop to 9600 baud, 8 bit, 1 stop bit, no parity. We've tried both no flow control and Xon/Xoff. We get the same results hooking up to the serial port on a working SPARC server, so it's probably something in our setup rather than a fault with the server. How do we get access to to serial console so we can work out what is stopping this box from getting to the network? Is there a special sun adapter we need to get/make to get the serial link working?

  • Just one client bound to address and port: does it make a difference broadcast versus unicast in terms of overhead?

    - by chrisapotek
    Scenario: I am implementing failed over for a network node, so my idea is to make the master node listens on a broadcast ip address and port. If the master node fails, another failover node will start listening on this broadcast address (and port) and take over. Question: My concern is that I will be using a broadcast IP address just for a single node: the master. The failover node only binds if the master fails, in other words, almost never. In terms of network/traffic overhead, is it bad to talk to a single node through a broadcast address or the network somehow is smart enough to know that nobody else is listening to this broadcast address and kind of treat it as a unicast in terms of overhead? My concern is that I will be flooding my network with packets from this broadcast address even thought I am just really talking to a single node (the master). But I can't use unicast because the failover node has to be able to pick up the master stream quickly and transparently in case it fails.

  • Do you really need cable management for a cabinet with just switches and patch panels?

    - by ObligatoryMoniker
    We are about to start wiring out a building expansion and our vendor has laid out the racks in the following configuration: Option 1 1U Fiber patch panel 2U Cable Manager 2U 48 port Patch Panel 2U Cable Manager 2U 48 port Patch Panel 2U Cable Manager 1U 48 port Switch 2U Cable Manager 1U 48 port Switch Total = 15U All the patch panels would be connected to the switches with 1ft+ cables fed through cable management. What I am considering instead is: Option 2 1U Fiber patch panel 1U 24 port Patch Panel 1U 48 port Switch 2U 48 port Patch Panel 1U 48 port Switch 2U 48 port Patch Panel Total = 8U All of the patch panels would be connected to the switches with .5 ft cables directly on their face with the top 24 ports of each switch patched to the patch panel above it and the bottom 24 ports of each switch patched to the patch panel beneath it which would not require any cable management. If I go with option 2 it save all of the space used by cable management and allows us to keep adding on switches and patch panels at the end without having to re-cable all of the patch panels above. Our vendor has indicated that this is not best practice and that .5ft cables will introduce cross talk. I could understand that being the case if we were connecting the .5 ft cable directly into another switch but we are connecting it to a patch panel that likely has another 150 ft cable run from the back of the patch panel out to the port in the building in which case the real resulting cable is 150.5 ft at minimum before even connecting it to a PC. It seems like it makes much more sense to go with option 2. It is easier to expand, saves space, and saves money on cabling and cable management. Does this kind of configuration make sense or is there a legitimate reason to choose Option 1 over Option 2?

  • How to stop IIS7 from listening on a specific IP address and port?

    - by webworm
    I am trying to install Apache on Windows Server 2008. The installation ends with a warning that the IP address I configured Apache to listen on cannot be bound. When I use netstat -a -p tcp to see if any processes are listening on the IP address and port I see several entires .. one of which shows as listening on 0.0.0.0:80. Here is a partial list of the output. Proto Local Address Foreign Address State TCP 0.0.0.0:80 MYSERVERNAME:0 LISTENING This looks to be IIS7 listening on all IP addresses on port 80. The confusing thing is that I stopped IIS7. All websites are shown as stopped. I tried iisreset /STOP as well as using the IIS7 Manager, yet something is still listening on 0.0.0.0:80. I have even made sure that every web site is bound to another IP address other than the one I want freed for Apache. Has anyone else run into this?

  • The cable of my USB port hub is too short - what to do?

    - by Anna
    Hi, I just bought a new USB port hub "MSY USB 2.0 4-port hub". It has two inputs: A small USB entrance input for external power (?) The problem is that the cable that comes with the hub (small USB on one end, large USB on the other - to input into my computer), is too short for my needs. Is there a solution to this? buying a longer cable might be risky, I know that it might cause problems with power. Is there anything else I can do to make it work? Thanks.

  • Can I directly open an MMF Cash Drawer through RJ-11 port?

    - by roviuser
    My aunt bought this cash drawer at an auction recently and has tasked me with figuring how to open it via a computer. We have the key (pictured) and can open it manually, but I'd like to be able to plug it directly into a computer and open it via some sort of program or script. It has a built in rj-11 cord coming out of the back of it. Initial research shows that it might usually be used with a printer, but I want to be able to connect it directly to the computer. Edit: this needs to be able to work with windows 7. Edit2: http://imgur.com/a/czEMs imgur gallery of the innards.
