  • Dual NIC internet access

    - by JavaRocky
    Q1. If a computer had two NICs, lets say windows, on which interface would HTTP traffic (or any for that matter) go out on. Not sure how the routes table would look like. Q2. If one of the NICs link becomes unresponsive, would traffic be automatically routed to the other NIC? Thanks.

  • Network connection to Firebird 2.1 became slow after upgrading to Ubuntu 10.04

    - by lyle
    We've got a setup that we're using for different clients : a program connecting to a Firebird server on a local network. So far we mostly used 32bit processors running Ubuntu LTS (recently upgraded to 10.04). Now we introduced servers running on 64bit processors, running Ubuntu 10.04 64bit. Suddenly some queries run slower than they used to. In short: running the query locally works fine on both 64bit and 32bit servers, but when running the same queries over the network the 64bit server is suddenly much slower. We did a few checks with both local and remote connections to both 64bit and 32bit servers, using identical databases and identical queries, running in Flamerobin. Running the query locally takes a negligible amount of time: 0.008s on the 64bit server, 0.014s on the 32bit servers. So the servers themselves are running fine. Running the queries over the network, the 64bit server suddenly needs up to 0.160s to respond, while the 32bit server responds in 0.055s. So the older servers are twice as fast over the network, in spite of the newer servers being twice as fast if run locally. Apart from that the setup is identical. All servers are running the same installation of Ubuntu 10.04, same version of Firebird and so on, the only difference is that some are 64 and some 32bit. Any idea?? I tried to google it, but I couldn't find any complains that Firebird 64bit is slower than Firebird 32bit, except that the Firebird 2.1 change log mentions that there's a new network API which is twice as fast, as soon as the drivers are updated to use it. So I could imagine that the 64bit driver is still using the old API, but that's a bit of a stretch, I guess. Thanx in advance for any replies! :)

  • ESXi 4.1 CentOS 6.X eth0 unnavailable

    - by L.K.
    I don't usually ask for help so directly, usually google have all i need but this time i'm seriously lost. Hope you can help me .s The thing is, i have a server with Vmware ESXi 4.1 and 5 already running and configured virtual servers, but whenever i try to make a new one on CentOS 6.X it leaves me without eth0 to be activated in any way. When installing CentOS, in the screen of localhost.localdomain i try by the button in the left down corner of the screen to make eth0 connect automatically but it tells me a NetworkManager Error: cannot start eth0. So...in command line once the CentOS is already installed, i have configured ifcfg-eth0 and manually tried to take up the eth0 but when i restart network service "Bringing up eth0: Failed" and sometimes even "shutting down eth0: Failed" Thanks in advance

  • Windows 7, network connection with no default gateway: any way to change the "Unknown network" statu

    - by e-t172
    Hi, I have a computer running Windows 7 Pro RTM. This computer has two network connections: A Wi-fi connection to the Internet (through a home router) which works just fine. An OpenVPN virtual network connection. More precisely, this is a virtual Ethernet connection which behaves exactly like a physical Ethernet wired connection. My problem is that the "Network and sharing center" shows "Unknown network" for the OpenVPN connection. After some research I found that logical networks (outside a domain) are identified by the MAC address of the default gateway of the connection. Problem is, the OpenVPN connection has no default gateway: it is a private network, so I don't need one... Consequently, the "Unknown network" is always considered public, so the firewall is always in "public mode", which I don't want. Plus, I can't rename "Unknown connection" or anything (which makes sense), so it is kinda ugly. My goal is to define a proper logical network for the OpenVPN connection with the private profile. I know of some workarounds (disable the firewall, modify security policy to make all unknown networks "private") but they're still workarounds. I just want my clients to connect to the VPN without having to disable their firewall settings, without changing global configuration with potential side-effects (the "security policy" solution) and without having to look at an ugly "Unknown connection" in the Network and sharing center. Is there any way I can do this? I tried to check what was going on in the registry (HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList is interesting), but I still didn't find a way to "force" the OpenVPN connection to be assigned to a logical network. Any help would be very appreciated. A related question showed up at Superuser: http://superuser.com/questions/37355/windows-7-cant-identify-network/37422

  • Iomega Home Media Network Hard Drive: Accesing the data in the disk?

    - by JJarava
    Hi all! I have an Iomega Home Media Network Hard Drive, 1TB, and lately I can't access the data on the drive. The shares (both built-in and created by me) are there, the security works, but when trying to access the data I get a "The network path was not found" message which is worrying, to say the least. I'd like to know if there is a way to get the data off the disks somehow, as some of the data in the drive (ie, pictures and videos of my 1.5 yrs old son) is hard if not impossible to find otherwise. Thanks a lot Javier

  • Why Does Wireless Gear Degrade Over Time?

    - by bahamat
    I saw this originally posted on slashdot, but their comment format is not conducive to actually getting a correct answer. Having directly experienced this phenomenon myself, I'm now asking here where I think I can actually get an educated answer. Here's the original question verbatim: Lately I have replaced several home wireless routers because the signal strength has been found to be degraded. These devices, when new (2+ years ago) would cover an entire house. Over the years, the strength seems to decrease to a point where it might only cover one or two rooms. Of the three that I have replaced for friends, I have not found a common brand, age, etc. It just seems that after time, the signal strength decreases. I know that routers are cheap and easy to replace but I'm curious what actually causes this. I would have assumed that the components would either work or not work; we would either have a full signal or have no signal. I am not an electrical engineer and I can't find the answer online so I'm reaching out to you. Can someone explain how a transmitter can slowly go bad? Common (incorrect, but repeated) answers from slashdot include: Back then your neighbors didn't have wifi, now they do. They drowning you out. I don't think this is likely because replacing the access point with a new one and using the same frequencies solves the problem. Older devices had low transmit power. Crank that baby. As mentioned by a FreeBSD wireless developer this violates regulations and can physically damage the equipment. It was also mentioned that higher power in one direction is not necessarily reciprocated. This shows higher bars, but not necessarily a better connection. Manufacturers make cheap crap designed to wear out. This one actually may be legitimate although it is overly broad. What specifically causes damage over time? Heat? Excessive power? So can anyone provide an informed answer on this? Is there any way to fix these older access points?

  • Cisco ASA: Routing packets based on where the connections started from

    - by DrStalker
    We have a Cisco ASA 5505 (version 8.2(2)) with three interfaces: outside: IP address 11.11.11.11, this is the default route inside: IP address 10.1.1.1, this is the local subnet newlink: 22.22.22.22, this is a new internet connection. We need to move VPN users from the 11.11.11.11 address to the 22.22.22.22 address, and we're using SSH on the ASA as to test and sort out the routing. The problem we have is this: If we define a particular IP as being on a static route out the newlink interface then it can SSH to 22.22.22.22 fine. If we do not define a static route then the traffic hits the ASA, but the return traffic does not come back over newlink; presumably it gets sent over the outside interfcae as that is the default route. We can't define a static route for each remote endpoint because there are dialup VPN users, who obviously change IP a lot What we need to do is configure the ASA so if a connection comes in on the newlink interface then the outgoing packets for that go over the newlink interface, not the default route. With iptables this should be do-able by marking the connection and doing mark-routing, but what is the equivalent for a Cisco ASA?

  • PXE booting LACP hosts on Force10 S50N with FTOS

    - by lolwutreddit
    Hardware: S50N Firmware: FTOS 8.4.2.6 Problem: We're trying to PXE boot some servers that are connected via port-channel interfaces with LACP. Current Work-around: we PXE boot a server with a single interface (eth0), and then use a Perl script to turn up the port-channel interfaces after the server is built. Details: Is anyone doing anything similar on Force10 S50 switches with FTOS? If not, is anyone doing this on another S series, or larger chassis-based Force10? I'm wondering if Native VLAN will solve this, since ports in a port-channel cannot explicitly have a VLAN set, and they don't seem to use the tagged or untagged VLAN that the port channel is in. I will confirm this next (I think it's the only thing I haven't tried) Juniper Example: http://broken.net/openindiana/how-to-pxe-boot-systems-on-lacp-using-juniper-switches/ Cisco: there are plenty of documented ways to solve this issue on IOS and Nexus Update/Edit: since there seems to be no way to use interface or port-channel mode commands to get the individual interfaces to show up in spanning-tree (rtsp in this case), the ports should never go into a forwarding state. I'm not going to mess with it anymore unless a) someone that has experience passes it on, or b) Force10 comes up with a solution for this (I'm guessing it will only be introduced on other S platforms (S55, S60), since the S50 seems to be near EOL). I'm basing that on the fact that the Open Automation type features are only being supported on the newer switches.

  • Cannot run a VM with more than three network interfaces with KVM

    - by Bostonvaulter
    I'm running KVM on top of Ubuntu 10.10 Server I can create VM's (Virtual Machine) and network interfaces fine but I cannot seem to add more than three network interfaces. As soon as I have a VM with four network interfaces it gets stuck on startup at the starting SeaBIOS page with this message: Starting SeaBIOS (version pre-0.6.1-20100702_143500-palmer) So far I've verified this with two VM's, a Ubuntu 10.10 desktop and a Vyatta router. The specific network hardware I assign to the VM's doesn't seem to matter. I'm trying to have one bridged interface and three private networks using Vyatta to route between them. Does anyone know why I can't run a VM with more than three network interfaces? Edit: Additionally the KVM thread responsible for the specific VM hangs using ~100% CPU (i.e. one core). Here's the command for the process that is hanging: /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name vyatta -uuid 6dff7c94-6810-423e-5fea-fec10da0e9b7 -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/vyatta.monitor,server,nowait -mon chardev=monitor,mode=readline -rtc base=utc -boot c -drive file=/home/rams/virtual-machines/vyatta.img,if=none,id=drive-ide0-0-0,boot=on,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -device rtl8139,vlan=0,id=net0,mac=00:54:00:be:cc:4b,bus=pci.0,addr=0x3 -net tap,fd=97,vlan=0,name=hostnet0 -device rtl8139,vlan=1,id=net1,mac=52:54:00:da:59:ed,bus=pci.0,addr=0x5 -net tap,fd=98,vlan=1,name=hostnet1 -device rtl8139,vlan=2,id=net2,mac=52:54:00:ce:22:b6,bus=pci.0,addr=0x6 -net tap,fd=99,vlan=2,name=hostnet2 -device rtl8139,vlan=3,id=net3,mac=52:54:00:1e:bc:46,bus=pci.0,addr=0x7 -net tap,fd=101,vlan=3,name=hostnet3 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -vnc 127.0.0.1:0 -k en-us -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 Edit: I've also found an error in dmesg that might be related (it also shows up when running virtd in verbose mode): 14:47:24.399: warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit status '1', qemu probably failed I've also tried disabling app armor but that doesn't seem to make a difference.

  • KVM-Guests can't get past bridge - no internet connection

    - by tmn29a
    I'm running a backported KVM on a Debian Squeeze. ATM the KVM-Guest can't connect to the internet through the bridge I have set up. The guests can reach each other, the host but nothing outside. I can neither ping, nslookup or do anything to a remote address. The guest are configured to have a static IP. When I didn;t have the bridge but a virtual bridge (the KVM-default) the guest could connect fine. After setting up the bridge things broke, so I think the problem lies there. # The loopback network interface auto lo br0 iface lo inet loopback # Bonding Interface auto bond0 iface bond0 inet static address 10.XXX.XXX.84 netmask 255.255.255.192 network 10.XXX.XXX.64 gateway 10.XXX.XXX.65 slaves eth0 eth1 bond_mode active-backup bond_miimon 100 bond_downdelay 200 bond_updelay 200 iface br0 inet static bridge_ports eth0 eth1 address 172.xxx.xxx.65 broadcast 172.xxx.xxx.127 netmask 255.255.255.192 gateway 172.xxx.xxx.65 bridge_stp on bridge_maxwait 0 Thanks in advance for your help !

  • Magento - Users unable to login from corporate networks with Bluecoat / F5 Load balancers

    - by user1330440
    Hoping someone has come across this issue before with Magento and corporate clients. We have two clients for our Magento site who both have their internal networks setup using bluecoat security devices and F5 load balancers. Some users within these networks are unable to login to Magento - Magento eventually is sending a 302 redirect to /index.php/ when users attempt to log in. Through our testing, the problem appears to be isolated to this setup - we can log into the accounts in question from anywhere outside of these networks without issue, and if the client tries to access the site without going through the F5 load balancer, they are able to log in successfully. Strangely enough, the issue only started occurring for the two sites the day after we introduced a system upgrade which added a new site to the Magento installation. The system upgrade should not have affected any standard login functionality, and as said, the problem does not appear to be with the users in question, but with where the users are accessing the site from. Initially we thought the issue might have something to do with communications between the client's networks and the network which the server was hosted on, so we've tried moving the server to different hosts, but this has not helped. I'm currently waiting for more info from the clients on exact devices / models used in their network setup. I will update this post if more information becomes avaliable. Magento version is enterprise edition of ver. 1.9.0.0 Does anyone know of any tucked away Magento settings that might be able to cause this kind of behavior? Experience with this kind of set-up and ideas for things to look at? All help and ideas for things to follow-up would be appreciated - as this is a current production issue for a large number of users. I will respond asap with any requests for additional information on the topic, but currently am not able to disclose any identifying information on the project in question, and/or the clients experiencing issues. Thanks in advance for any assistance offered :) Note: This question has also been posted on the Magento forums: http://www.magentocommerce.com/boards/viewthread/277917/ And also on Stack overflow (Moved here as a commenter thought this site may be better suited): http://stackoverflow.com/questions/10133978/magento-users-unable-to-login-from-corporate-networks-with-bluecoat-f5-load

  • can't resolve host (A) but FQDN is fine

    - by user1431356
    I am getting inconsistent name resolution locally with DNS I have 3 2012 Standard servers and some weirdness on 1. It is a standard install with IIS role added. TEST01 is a dev server. 192.119.1.220 with a host header of TEST01. DATA01 runs internal DNS on .240 and all servers and clients point here for DNS. There is a forward in DNS to 192.119.1.1 (router) with ISP external DNS #s mapped. if I ping TEST01 from a non AD machine, it I get "Could not find Host TEST01" If I ping TEST01 from a domain machine(another server), it resolves the IP but does not respond. if I ping TEST01.AD.local, DNS resolves the IP, but times out. I can access IIS by entering http://test.WWWDOMAIN.com and I can RDP to it, just not ping. Any idea where I should start?

  • Cross platform support for network attached USB hubs?

    - by larsks
    I am looking at network-attached USB hubs in order to run licensed software in a virtualized environment when hardware dongles are required. Are there any solutions that will work with both Linux and Windows? Most of the dedicated devices -- such as the Zonet ZUH2214 or the (oddly expensive) Digi AnywherUSB/2 -- appear to be Windows-only. Linux has the the USB/IP project, for which there appear to be Windows drivers, but the last "News" post on the site was in 2007, so I'm not entirely confident about the viability of the project. Has anyone out there found a solution that will work well in both environments?

  • Running a small IPTV station

    - by nixterrimus
    I'm looking to run an iptv station for my dorm. I know I can serve multicast so that's not a problem. The station will serve out podcasts and other cc licensed content. The target endpoint is xbmc- a media center. So far I know that I need to serve an rtp stream over udp that's streaming an mpeg-4 avc main or high profile with aac ( or ac3 ?) audio. I've had some luck using vlc with vlm to stream but it seems limited. What are my other options?  Everything has to run on Linux- hopefully open source. How can I use playlists and not live streams? What are my software options?

  • Cannot access virtual machine via ping from the physical host machine

    - by Kenni
    I'm installing a FreeBSD Server on VirtualBox. I set up the IP address (192.168.10.5) for the virtual server to run a mail server and the host computer(Windows 7) with 192.168.10.184. The two machines cannot communicate or connect to each other. I cannot ping from the virtual machine to the host and vice versa. The host machine connects to a LAN. I want the mail server to run frm a VMachine. I think it's a problem with the network configuration of the virtual machine.

  • How could two processes bind onto the same port?

    - by Matt Ball
    I just ran into an issue where a request made to localhost:8080 from curl was hitting a different server than the same request made from inside Node. lsof -i :8080 revealed that two processes were both binding onto the same port: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME node 51961 mball 14u IPv4 0xd980e0df7f175e13 0t0 TCP *:http-alt (LISTEN) java 62704 mball 320u IPv6 0xd980e0df7fe08643 0t0 TCP *:http-alt (LISTEN) How is this possible? Were they binding onto different interfaces? Or was it the IPv4 vs 6? If you're curious, node was hitting the other node process, curl was hitting the java process. The java process was started after the node process.

  • How do I add a broadcast IP to the loopback interface under os/x using ifconfig when my machine has no network?

    - by bandodeotarios
    I'm new to advanced network administration and I would like to do some testing with UDP broadcasting, so I need a broadcast address on my loopback interface. The machine is offline, in other words, there is no network. How can I accomplish that through ifconfig without having to buy a switch as one user in the comments suggested. In Linux all i have to do is use 127.255.255.255 and broadcasts work fine without any network or any switch. If I have a network i can just use 255.255.255.255, obviously.
