• Unable to access internet if wireless enabled

  - by balki

  The following is my route output. eth0 is my wired network and eth1 is my wireless network. Only wired one has access to internet. If I enable wireless, I am not able to access internet, it tries to access via eth1 and I get 404 page of the wireless router. Why does eth1 have higher preference though default is eth0 (link)?

• Can't connect to the internet in Windows Vista

  - by Kola

  I have a Windows Vista computer which i have used for about 2 years without any issues. Recently, i started having problems connecting to the internet with this Vista computer. My other XP Computers are fine and can connect to the Internet. Regardless of wired or wireless connection, i am unable to get the Vista computer connected to the web. The Status remains "Limited" for IPv4 and IPv6. It also shows unidentified Public Network, and is able to connect to the router. However, there's a disconnection between the router and the internet. Any help will be greatly appreciated, i have been on this for 4 weeks now.

• Failover NIC with Windows 7 running Apache Server

  - by Benjamin Jones

  I have a Apache Server running on a Windows 7 Desktop for a internal website (Intranet). I am trying to figure out how I can make this system as failover safe as possible. One thing I want to do is use the 2nd NIC card that is currently disable. I only have one gateway address to my router. I do not have any computer running a Server O/S. If NIC1 crashes by chance(just humor me!), how could NIC2's IP take on the host name (I have mapped in host file) . I don't really care if the static IP of NIC2 changes seeing that the host name is the only thing I need. Could I add two IP's to the host file, with same host email and maybe create some script that will run IF NIC 1 fails? OR is there any failover software that will do this for me?

• What is the fall off of subsecond throughput on Ethernet Network Interfaces

  - by Kyle Brandt

  On a network interface, speeds are given in term of data over time, in particular, they are bits per second. However, in the uber-fast world of computing -- a second is kind of a really long time. So for example, given a linear falloff. A 1 GBit per second interface would do 500MBit per half second, 250Mbit per quarter second etc. I imagine at certain units of time, this is no longer linear. Perhaps this is set by ethernet frequencies, system clock speeds, interrupt timers etc. I am sure this varies depending on the system -- but does anyone have more information or whitepapers on this? One of the main reasons I am curious is to understand output drops on interfaces. Even if the speed per second is much lower than the interface can handle -- perhaps there are spikes that cause drops for only small numbers of milliseconds. Perhaps various coalescing would hide this effect -- or perhaps increase it on the receiving interface? Do queues make a difference here? Example: So given if this is linear down to the MS we would have 1Mbit/MS, and if Wireshark isn't distorting what I see, should I see drops when I have a spike beyond 1Mbit?

• Siege - running a stress test benchmark

  - by morgoth84

  I need to do a benchmark test of a HTTPS server using Siege, to see how it behaves under massive load. I'm initiating tests from another machine which is quite powerful and it is connected to the same physical switch the server is connected on. But when I initiate a test, I can't get it to make more than 170 requests per second. With this load the server's CPU usage is at 15-20% and the average response time for a request is approx. 0.03 seconds. Load of the client machine is approx. at 10%. So, I gradually increase the number of users in Siege (the number of worker threads) and request rate linearly increases up to 170 reqs/sec, but it never gets over it. No matter how many more worker threads I start, the load on the server is never more than 20% (and the client's load also doesn't increase any more). How can I overcome this? I've googled a bit and found out that after a request is completed, a socket associated with one ephermal port remains in WAIT_TIME state for some time during which it can't be reused. I tried to overcome this by doing these things: sysctl -w net.ipv4.ip_local_port_range="1024 65535" echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle Oh, and the client machine is a Linux (RedHat, I think, but I'm not sure). Any help would be appreciated.

• Lenovo tools for windows 7: can't re-enable wireless

  - by pcampbell

  Consider a netbook - Lenovo S10e with Windows 7 and the S10 Lenovo power management tools. Machine has factory BIOS. Fn+F5 is the key combo to toggle the wireless radio on/off. The tool allows the disabling fine; works as expected. The problem is that the re-enable doesn't work, or is confusing on how to re-enable. Previously tried without success: Fn-F5 Fn-Ctrl-F5 Fn-Shift-F5 Fn-Alt-F5 Here's the onscreen display: Question: How can you re-enable the wireless radio using the Function key on a Lenovo netbook?

• OS X: How to force traffic through a specific SOCKS proxy on a per-app basis?

  - by GJ.

  I'm running a certain desktop app (actually via AIR if it makes any difference) which doesn't have any built-in proxy configuration settings. I need to get all traffic just from this app directed through a secure SOCKS proxy. This implies I can't use the global network preferences, as these would affect many other apps. Is there any way to force all network communication through a given SOCKS proxy on a per-app basis?

• Vista to Vista network visability issue

  - by Sk93

  Hi All, I've got a Vista Business PC and a Vista Business Laptop connected via a virgin media router (Netgear CG2100D) and I cannot get the two machines to see each other correctly over the network. The laptop is connected via wireless, whilst the pc is wired. Both are set to recieve their network settings automatically (DHCP) and both have the windows firewall (the only firewall on either) turned off completely. I can ping each machine fine from one another using the ip addresses, and I can also connect via \. However, connections via \ fail, and I cannot see the machines in the network map. I have tried turning netBIOS to be "always on" on both adapters, but this makes no difference. I've been messing around pretty much for 6 hours now and am getting quite fustrated by this! (my original aim was to get media sharing working, but I've pretty much abandoned that for now). Any ideas?

• Can't get nmap to work under Windows 7 64 bit

  - by jitbit

  I'm trying to install and run the nmap tool to test my server, but it keeps saying Note: Host seems down. If it is really up, but blocking our ping probes, try -P0 and showing all the server ports are closed. Which is not true - the server is up and has lots of open ports. Any ideas? UPDATE: Just to clarify - the server can be pinged and port-scanned fine by other programs. It's juts nmap that does not work. Even "google.com" seems to be down for nmap.

• Why PowerConnect and Juniper are so rare ? Why do enterprises stick with Cisco ?

  - by Kedare

  Hello ! I have a little question, I'm actually studing in IT in France, and when looking on alternative on the very [...] very expensive Cisco equipment, I've found Juniper and DELL PowerConnect pretty attractive on features and price, but I rarely see something else than the classics Cisco/LinkSys, HP Procurve and Netgear.. Why it's so rare to find those switch ? They looks really great but... I've never seen any Juniper or Powerconnect... Why do enterprises stick with the expensive Cisco ? I've tried to find how to buy both, it's quite easy with PowerConnect, everything is on the DELL website, but it looks it's very hard to find Juniper equipment in France :( Thank you !

• XenServer 5.6.1-fp1. Can't get network working

  - by casey_miller

  I have a PC where XenServer 5.6.1 fp-1 has been successfully installed. I've manually set the network settings: 192.168.1.50 255.255.255.0 192.168.1.1 but it's set to xenbr0 iface. While eth0 is empty. When I click on "Configure Management Inteface" it shows that eth0 is connected. But when I ping a default gateway (which is 100% should be accessible) it fails. I used to another shell (Alt+F3) and logged as root. I also failed to ping. with both: ping -I eth0 192.168.1.1 and ping -I xenbr0 192.168.1.1 Be assured that: Cable works Ethernet adapter is 100% functional (prev OS was Ubuntu it was working) There is no firewall rule to deny anything. (everything is allowed) So the question is: What is a problem???

• How do I bridge a connection from Wi-Fi to TAP on Mac OS X? (for the emulator QEMU)

  - by penx

  I'm trying to setup a bridge between my Wi-Fi connection and an emulator (QEMU). I need a virtual machine to be on the same LAN as the host, with its own IP address. QEMU requires using a TAP (virtual network device) so I have installed tuntaposx, have it running, and can open up QEMU using a TAP: qemu-system-arm -kernel zImage.integrator -initrd arm_root.img -m 256 -net nic -net tap,ifname=tap1 -nographic -append "console=ttyAMA0" I have a script that configures the bridge once QEMU has opened up the TAP interface: sysctl -w net.link.ether.inet.proxyall=1 sysctl -w net.inet.ip.forwarding=1 sysctl -w net.inet.ip.fw.enable=1 ifconfig bridge0 create ifconfig bridge0 addm en1 ifconfig tap1 0.0.0.0 up ifconfig bridge0 addm tap1 ifconfig bridge0 up If I manually set an IP on the VM, I can ping from the VM to the host, but not from the host to the VM. Also, I can't access the rest of the network from the VM - including not being able to set an IP over DHCP. Any ideas?

• Forward all traffic from one IP to another Ip on OS X

  - by Josh

  This is related to this question I just asked... I have two IP address on my iMac I want to "bridge". I'm not sure what the proper terminology is... here's the situation. My iMac has a firewire connection to my laptop and an ethernet connection to the rest of my office. My laptop has an ip of 192.168.100.2 (on the firewire interface). My iMac has an IP of 192.168.100.1 on the firewire interface, and two IPs, 10.1.0.6 and 10.1.0.7, on it's ethernet interface. If I wanted to forward all traffic coming in from 192.168.100.2 on my OS X machine to go out on IP 10.1.0.7, and vice-versa, can this be done? I assume I would use the ipfw command. Essentially I want to "bridge" the firewire network to the ethernet network so my laptop can see all the machines on the 10.1 network, and all those machines can see my laptop at 10.1.0.7. Is this possible?

• Detecting what causes the delay between entering a domain name and load of the page

  - by Quintin Par

  My website takes awfully long time after entering the domain name and before the content starts showing up. I assume this is something to do with the dns resolution or the networks. How do I go about troubleshooting this problem? Where do I start and what tools do I need? I know I’ll need nslookup and traceroute. What else will I need?

• How to know my wireless card has injection enabled?

  I am playing around with aircrack.

• How can I make VNC faster?

  - by NickAldwin

  I need to remotely access and use my work computer a few times a week. I want to use VNC because of the price. I've used VNC before, mostly on my own network, where it's fast. However, VNC over the internet is incredibly slow. Even at 256 colors and lower, with Aero turned off, it is unbearably slow. I recently used Ammyy Admin to connect to do something requiring a quick reaction time. Ammyy was really fast, with almost no lag, and it was running in full color with Aero on! How can I make VNC faster, like Ammyy is? I'd use Ammyy, but I would probably run into the 15hr/month limit pretty quickly. Any suggestions? [EDIT] I'm currently using UltraVNC.

• Why is Windows 7 so slow to log-on when my Wireless USB dongle is plugged in?

  - by Sam

  I'm using an Edimax Wireless USB dongle (model EW-7711UTN) on Windows 7 64-bit. The dongle works brilliantly (it was truly plug-and-play) except for one thing. I've noticed that if the dongle is plugged in whilst I'm logging on to Windows it introduces a massive delay - after I type in my password and hit enter, Windows shows the "Welcome" screen, then the screen goes black for 2 minutes or so (with just the cursor showing) before finally displaying my desktop. If I unplug the dongle before I enter my password, Windows goes straight to my desktop. Even though the dongle didn't appear to need drivers for Windows 7, I did try downloading the latest ones from the Edimax website, but that made no difference.

• How to get all IPs of a domain?

  - by DenMark

  How can I get all IPs of a domain name, say, www.google.com? Of course, nslookup and host command will give me IPs of a domain. But what shall I do if I want a list ALL (or, at least a lot more than just one or two..) IPs of that domain?

• dhcp client service won't start

  - by xyious

  I have a Laptop with 2 network interfaces and neither will get an IP address through dhcp. I found out that the dhcp client service didn't start. Upon manually starting it gives the error 2: File not found. I have checked that the files were there (both svchost and dhcpcore .dll), the local service account has read access to the system32 folder, the path in the registry is also correct and I can access the file. I have tried to netsh winsock reset and ip reset all. I have even added the local service account to the administrators group. sfc /scannow also came up clean. I have no idea what else I can try. Any suggestions are welcome. (side note it's a windows 7 32 bit, atheros wlan, deinstalled avira before any of the other troubleshooting)

• Terrible ping time with TP-Link wireless router

This happens from time to time. I'd restart the router, and then it'll have a 1-2 ms ping for a while, and then back to terrible ping. Is it just a poor quality router? Suggestions? Thank you

• VPS hosting for a social network

  - by Jana

  Hi, I've developed a social network and I've been using shared hosting for that since it was launched. With that I wasn't able to send emails in bulk in cases like "newsletters" and "invitations to join my site". Plus most importantly most of the mails I send ended up in user's SPAM list.I'm planning to move into VPS as it may not have limits added. I'm wondering what's the cheapest VPS host available. I'm not pretty much familiar with Linux commands and seeking cPanel to do the work for me. Will the following configuration suit for a "new" social network like mine which has a less load? 1000Mhz Guaranteed 512MB Guaranteed RAM 20GB (RAID) Disk Space 1000GB/month Bandwidth 2 IP(s) & 5 Backups Semi Managed Thanks in advance

• Server not resolving after restart

  - by DomainSoil

  I restarted our server today, and now cannot for the life of me get anything to resolve... I suspect it has something to do with our routes. I've tried numerous Google results to no avail. Here is as far as I've gotten: [root@www ~]# route -n Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.101 0.0.0.0 255.255.255.255 UH 0 0 0 eth1 0.0.0.0 192.168.1.101 0.0.0.0 UG 0 0 0 eth1 Things you need to know: Our server (CentOS 6.3) runs two virtual machines, one live, and one development. They mirror each other as much as possible, but I can't find where I've went wrong with the live server. The dev server works fine.

• How do I route traffic to website using a spcified network connection on Windows 7

  - by rwetzeler

  I want to route all traffic to a website over my wireless connection while the rest of the traffic using my lan. What I tried was first finding out the IP address of the website I want to go to. For example, lets say pandora.com. I found it resolves to 208.85.40.20. I have entered that entry into my hosts file. I then added that route using route add 208.85.40.20 mask 255.255.255.255 WirelessIP. It doesn't seem to work however. Instead of using the IP address, is there a way that I can just say.. this URL to route over that connection? Does anyone know of a program that I can install that will do this.. possibly some sort of proxy or a software load balancer that can do this?

• Unidentified network: How to configure TCP/IPv4 for Win7?

  - by Zolomon

  When I try to connect to internet I keep getting the error "Unidentified network". I've tried numerous attempts at restoring access without success. IP release, flushing DNS cache, reinstalling NIC, reactivating NIC, resetting router and so on... I've read several times that it's my default gateway that's wrong. Currently I've had automatic IP/DNS configuration set without any problems, and then it stopped working for some reason. Anyone know how I specify the IP? My subnetmask is 255.255.255.0, default gateway is 192.168.0.1 but I have no idea how to determine what IP I should set. I use a D-Link DIR-655 and other computers on the network have IPs like 192.168.0.194, next is 192.168.0.197. (I'm completely lost and am trying to cool down after two weekends of debugging filled with despair.)
