  • "destination host unreachable" while ping attempt between 2 pc on 1 network

    - by Roberto Sadfasdf
    I have 2 computers in my network ones ip address is 192.168.2.31(PC-A) and the others is 192.168.2.33(PC-B). When I'm trying to ping from PC-B to PC-A it says: Pinging 192.168.2.33 with 32 bytes of data: Reply from 192.168.2.31: Destination host unreachable. Reply from 192.168.2.31: Destination host unreachable. Reply from 192.168.2.31: Destination host unreachable. Reply from 192.168.2.31: Destination host unreachable. Ping statistics for 192.168.2.33: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss) And when i'm trying the otherwise it tells me same message with ip address switched..They are both can connect to the Internet

  • smbclient -L host works. ping host doesn't work. What is missing

    - by DrorCohen
    I upgrade my ubuntu desktop to 13.10. When I say upgrade I mean installed on a new partition from scratch (old partition is available if To the problem: I'm trying to ping a host (Drobo-FS server) by it's netbios name. I get "Unknown Host". However running smbclient -l HostName - give me all the output in the world. Stracing the ping I can it tries to use resolv.conf (expected fail) and then when accessing mdns stuff it fails (no mdns.allow file) and exits. Here's the host line from /etc/nsswitch.conf: hosts: files wins mdns4_minimal [NOTFOUND=return] dns mdns4 I've added wins right after files (and also tried before dns. Nothing helps. Reboot after every change. What am I missing?

  • Why is Windows 7 not following all routes?

    - by GigabyteProductions
    My computer is connected to my secondary router that's running the 192.168.42.0/24 network and my computer also has a route that directs anything on that network to the router, but for anything on that network other than the router itself, it get's the ICMP response of Reply from 192.168.42.194: Destination host unreachable. (with 192.168.42.194 being my computer). Every other network works, like all of the internet, or addresses on my primary router like 192.168.1.*, just not on the 192.168.42.0/24 network... route print returns: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.42.1 192.168.42.194 276 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 192.168.42.0 255.255.255.0 On-link 192.168.42.194 276 192.168.42.194 255.255.255.255 On-link 192.168.42.194 276 192.168.42.255 255.255.255.255 On-link 192.168.42.194 276 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 192.168.42.194 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 192.168.42.194 276 =========================================================================== Persistent Routes: Network Address Netmask Gateway Address Metric 0.0.0.0 0.0.0.0 192.168.42.1 Default =========================================================================== The only time anything is supposed to send an ICMP Host Unreachable response is when there's no route to it, right? So, why is my own computer sending that to ping or tracert when I have the route of 192.168.42.0 with the mask of 255.255.255.0? An IP address of 192.168.42.2 surely fits into that route. If I explicitly add a route for the IP address i am trying to access, it works, like: route add 192.168.42.2 mask 255.255.255.255 192.168.42.1 (the 192.168.42.1 right after mask is gateway, or the device to send the packet to so it can route it further), but why wont it work for the implicit route that's automatically on the table? I disabled my firewall, too (I use Comodo if anyone thinks this still serves as a problem). I'v even tried explicitly adding the gateway of 192.168.42.1 to the 192.168.42.0/24 route instead of it routing through 0.0.0.0's gateway, which is what On-link does. but that didn't work either, so it's not a gateway specification problem. If the host was really unreachable, it would be the router's IP address (192.168.42.1) sending that to me... This network is all of my creation, so there's no problem such as an administrator locking me out, because i am the administrator.

  • Can I make Windows behave like an ethernet hub?

    - by dromedary
    I have two machines A and C mutually connected to NICs on a third machine, B, as follows: A-B-C B is a Windows 7 machine configured with a bridge containing the A-B and B-C NICs, so that A and C can communicate. So far, so good. I need frames from A destined for B to also arrive at C. Essentially, I would like Windows to behave like a hub rather than a switch. Is there any way to do this? If you have any ideas at all, no matter how hacky or roundabout, I would love to hear from you! I have been tearing my hair out over this and by now I am willing to try anything. My only limitations are that I can't touch A or change to a different operating system on B.

  • how to switch played music when someone enters

    - by ymajoros
    My wife has a small shop, and she plays free licensed music. She can't legally play her own music when people outside of the family circle are present in the shop. How can I automatically switch music when someone enters? I was thinking of some bluetooth door detector and some custom software, but can't seem to find either. I'm a software architect/dev and can write it if necessary, but I'd prefer to use some existing solution. Any ideas on good hardware and software for this?

  • Windows has automatically mapped my network drives to my local disk - how do I stop it doing so?

    - by cyborg
    Windows XP decided when I logged on that because the network was unavailable at the time that two of my network drives should be mapped to my local drive so that data would be saved. All well and good but I need it to stop now so I can use my network drives again. I can't find anything relating to the feature but I can't remember the specifics of the message it gave me when it started this operating mode and Google searches for the sort of terms above leads me to a slew of irrelevancies. Any ideas? Thanks.

  • Router as primary DNS server, Server as alternate? (or vice versa)

    - by Jakobud
    We have a very small business network, with a typical cable modem hooked into a DD-WRT router. We also run a basic CentOS server that does a variety of things, including acting as the primary DNS server for the office. The reason we need an internal DNS server is because we do a lot of internal web development and use the DNS server to add/remove various local network URLs for internal website testing (like www.testsite.com.local). It's very important for us to be able to add/remove URL aliases easily to the DNS. The problem with this setup is that if we ever need to restart the CentOS server or take it offline for upgrades or whatever, then internet access for all computers on the network is lost. That's because each computer relies on that DNS server to access the Internet I guess? The router is online all the time and very very rarely has to be restarted. It would be nice if we could setup my router to be the primary DNS server but still be running DNS on my server. So we could still add my local testing website URLs to the DNS server in CentOS, but be able to also take down the CentOS server without loosing Internet access on the network. How would this be setup? Would I simply need to add both router + server IP addresses to each computer's IP settings? Is the router primary DNS and server secondary DNS server? Or vice versa? Or can one of the two serve as a fallback for the other? What (if anything) needs to be configured on both the router and server in order for them to recognize that the other DNS server exists on the network? Does anyone have any newb-friendly resources for setting up something like this?

  • DHCP server can't see other machines

    - by William
    Hi, I setup a private network from virtual machines and one of the machines is the DHCP server for the group. I want to specify a next-server for the DHCP server but I'm having trouble connecting to any of the machines that I lease IPs to. I'm just trying to do a simple ping/ssh to 10.0.0.252 (a machine with a lease) but it doesn't seem to respond. Any advice? I'm assuming I need to be able to connect to my next-server but maybe I'm wrong. Thanks.

  • Internet really slow or stops working on my computer but fine on my laptop and ipad

    - by Fr0zen1
    I know you are going to say that this has been answered already, but it hasnt. None of those solutions worked for me. So this is the problem, and it only occurs on my computer, my laptop,ipad and iphone are just fine. When I`m browsing the net, it laods webpages slow(my speed is 30mb down and 3mb up) and when I start downloading with a another application(steam, utorrent), my browser completely stops working, but the application thats downloading(steam, utorrent) continues to download with a fast spead(2-3mb/s) and I do not know why. I have this issue on all browsers. I have tried chrome, internet explorer and firefox. I have restored my windows but still the same issue and I also have kubuntu installed and it also has the same issue. I do not know why. Any help? Thank you

  • How to combine with openvpn, dynamic-ip?

    - by asfasdv
    Dear everyone, I am currently using openvpn to surf online to bypass censorship. Let me show you the initial scenario: before openvpn is turned on: IP: 1.2.3.4 (hypothetical, checked by visiting whatismyip.com/) after openvpn is turned on IP: 10.2.3.4 (this is also checked with whatismyip.com/, I assume this is where the vpn's exit point's IP ) Situation: Once I enable openvpn, I can still ssh into this computer by sshing into 1.2.3.4, even though visiting whatismyip.com/ says it's 10.2.3.4. However, I am on dynamic IP, I run a website, and am using tools (inadyn in particular) which pings the freedns.afraid.org (my dns server) and updates my ip. The messed up part is when inadyn does so, my dns changes the ip to 10.2.3.4, which is presumably the exit point of my vpn. How do I get around this? (Note that sshing into 1.2.3.4 STILL works).

  • How do I bridge connections in Debian?

    - by Josh
    In windows I can select Local Area Connection and Wireless Network Connection, right click and select Bridge Connections How can I achieve the same effect in Linux? (Debian to be exact) Pretty much I want Computer B to connect to Computer A via ethernet cable. Well Computer A is connected wirelessly. Allowing Computer B to get on the internet. == UPDATE == I've enabled IP forwarding and used the following iptables command: iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE I'm still unable to access the internet from Computer B though.

  • My Router is fast when i reset it but slows down seconds later

    - by hglocke
    I have a Belkin N wireless router which until recently worked perfectly fine. Now i have to reset the router every few minutes, otherwise it slows down to a crawl. What can I do? I have tried turning the routers firewall off, but it does not make any difference. As far as I'm aware there have been no recent firmware updates. EDIT: The other devices on my network (laptop and iphone) do not have this problem. I connect to the router using a TP-Link wireless network card and I have already tried uninstalling and installing the driver. Hopefully this will narrow down the problem significantly.

  • Mirror network packets from WiFi to Ethernet in an ASUS Router RT N53

    - by fazineroso
    I have an ASUS RT N53 router, running the default firmware (Linux 2.6.22 with busybox and uclibc). I need to capture data packets from some Wi-Fi devices I have connected to that router (iPad and some smartphones), but the router is not forwarding any package coming from Wi-Fi devices to the Ethernet Ports. Any idea how can I proceed? Available tools in the router are iptables (no tee option, though), ebtables, brctl... Currently the ethernet and Wifi devices are forming a bridge: # brctl show bridge name bridge id STP enabled interfaces br0 8000.50465dc06be2 no vlan0 eth1 No ebtables rules: # ebtables -L Bridge table: filter Bridge chain: INPUT, entries: 0, policy: ACCEPT Bridge chain: FORWARD, entries: 0, policy: ACCEPT Bridge chain: OUTPUT, entries: 0, policy: ACCEPT

  • Bringing the xenbr0 interface up on XEN under Ubuntu 8.04

    - by iyl
    I installed XEN on Ubuntu 8.04 using this tutorial: http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories but after I reboot with the XEN kernel, I don't have xenbr0 device. I see that network-bridge script runs and it creates peth0 device, but not xenbr0. I have a very basic IP setup, with a single static IP defined in /etc/network/interfaces. The only unusual thing is that my hosting (1&1) gave me a netmask 255.255.255.255, so I had to add the default gateway with this script: /sbin/route add -host 10.255.255.1 dev eth0 /sbin/route add default gw 10.255.255.1 Everything else is plain vanilla Ubuntu 8.04.

  • Is 50% download speed on a wireless G network normal?

    - by Bartlomiej Skwira
    I have a wired connection of about 36Mb/s, but my wireless speed is max at about 18-19Mb/s. I have a WRT54G-TM (T-Mobile, 802.11G) router with DD-WRT firmware - I've upgraded it to latest build. Done some settings changes: changed channel - 13 wireless network mode - G-only ACK Timing - 0 Fragmentation Threshold and RTS Threshold - 2304 Basic Rate - All Signal/Noise ratio: -46/-94, signal quality ~50-60%. Is this normal with G networks? Edit: The AP is located about 2 meters from laptop, no walls or metal objects, but its next to a TV. I've done a channel scan (had problems locating it, go to "Status - Wireless - Site survey" - lame naming) and everybody else is on channels 1 and 6. Switched to channel 11 but it didn't help. As for trasmit power I got best results with default 71mw. The antenna might be a factor, I'm using the default 2 antennas.

  • Outbound ports to allow through firewall

    - by dunxd
    This question was asked before, but in a rather general way. I'm asking more specifically based on my current requirements. We have a number of remote offices made up of a bunch of PCs and an ASA 5505 which is used as firewall and VPN termination point. In the offices we share the internet connection with one or more other organisations over whom we have very little control, asides from the config on the ASAs. For a bunch of reasons I'd like to lock down these ASA 5505s to only allow outbound traffic to ports used by applications we know we need. I'm putting a standard config to roll out to all the ASAs, and if we need to open up ports for the other orgs we can do it on request. But I want to leave open the most commonly required ports so we can get up and running without waiting on other folks technical staff to get back. I plan to allow the following TCP ports to support commonly required resources: POP3 (110 and 995) HTTP (80 and 443) IMAP4 (143 and 993) SMTP (25 and and 465) The question really is, what other ports do I need to leave open to allow for "normal" working. I've seen UDP port 53 for DNS as one. Are there any others that would be worth opening up? Just to note - I'll also be setting up monitoring systems to keep an eye on the ports we do allow. Any of the above could be misused of course. We'll also back all this up with signed agreements. But I'm aiming for a technical solutions where I don't have to start out with the full requirements of everyone we share connections with. See also: outbound ports that are always open

  • Blacklist a single access point of a wireless network

    - by Zr40
    At my university, one of the wireless access points is failing. When something tries to associate to the network using that access point, it deassociates the client, claiming 802.1X authentication failure. Other access points do work normally using the same credentials. The issue has been reported, but after a month it still has still not been fixed. Now, I'm looking for a way to blacklist the access point's BSSID, so the OS prefers other access points on the same SSID. How can I blacklist specific BSSIDs in either Mac OS X Snow Leopard or Windows 7?

  • Windows clients cannot access machine running DHCP server

    - by science9712
    I'm trying to setup a small LAN, using an Ethernet switch, an Arch Linux server, and around 10 Windows XP machines. This network has no outside connections. The Arch machine has a self configured ip address (configured with ip addr add 192.168.0.1 dev eth0), and acts as a DHCP server(using dhcpd). This portion works great, windows clients get IP addresses, the correct gateway settings, perfect. However, the clients cannot connect to each other, or to the dhcp server. When I run ping 192.168.0.1 on any client, I get no response, same happens if I try to ping any other client. On the gateway machine, I can't ping any of the clients either. Any help would be much appreciated!

  • Network bandwidth usage dashboard?

    - by SkippyFlipjack
    I have a couple of wifi access points hooked up to my home network, one of which I keep unsecured for some development I do; there are only a couple other homes within range and they've got their own wifi so it's not a big concern. I also have a Sonos system, Tivo, Roku, a couple laptops, a couple phones, an iPad and a desktop machine, all of which are internet-smart. So when my internet bandwidth tanks and it takes five minutes to load a YouTube video, I want to know what's going on, and there are many potential culprits. I'd like to be able to plug my MacBook into the primary router and see a nice little dashboard of the units on the network and what kind of bandwidth each is using at that moment. I could figure this out from WireShark or tcpdump but figure there has to be an easier way. I've tried a few different commercial products but none really presented the right info. Suggestions? (This may be a question for superuser since my Apple Time Capsule's SNMP capabilities are limited, but I figure admins of small business networks would have dealt w/ the same issue..)

  • Throughput and why do ISPs sell too much bandwidth?

    - by jonescb
    I hope the question made sense how I worded it. :) I've been wondering, maximum theoretical bandwidth is measured as RWIN/RTT (Window size / round trip time) Source 1 and Souce 2 So if a major city only 100 miles away gives me a ping of 50ms, and I have the default 64kb TCP window size then my maximum throughput will be 12.5Mb/s. Everything further away would give me a higher ping and therefore a lower throughput. Is there any reason to buy something like FiOS with a 50Mb/s or greater connection? Will you ever be able to reach that kind of speed? I know you can increase the TCP window size to increase throughput, but it has to be at both ends which is a deal breaker because you can't control the server. I'm assuming other network protocols like UDP aren't quite as affected by latency as TCP is, but how much of overall network traffic does non-TCP make up vs TCP. Am I just misguided about how throughput works? But if the above is correct, then why should a consumer like me buy way more bandwidth than can be realistically used. Maybe the only reason is for downloading multiple things at once, or one thing from multiple servers/peers?
