  • Dynamips Virtual Router not pinging external host after bridging

    - by maiky
    I have setup a virtual router image with dynamips and setup bridging between tap0 interface of the virtual router and eth0 and br0 with commands [root@cisco_host]# brctl addbr br0 [root@cisco_host]# ifconfig br0 up [root@cisco_host]# ifconfig eth1 0.0.0.0 [root@cisco_host]# brctl addif br0 eth1 [root@cisco_host]# ifconfig br0 192.168.0.100 netmask 255.255.255.0 up In dynagen configuration I have: f0/0 = NIO_tap:tap0 So, [root@cisco_host]# brctl addif br0 tap0 [root@cisco_host]# ifconfig tap0 up router(config)#int fa0/0 router(config-if)#ip address 192.168.0.101 255.255.255.0 router(config-if)#no shutdown After the configuration above I was expecting that from inside the router I could ping an external machine with IP 192.168.0.1 Actually from the host I can ping the external host 192.168.0.1 as well as 192.168.0.100 and 192.168.0.101. So what am I missing here? tap0 is bridged with br0 and in turn with eth1. So why the router is not pingable from 192.168.0.1 and vice-versa??

  • Port forwarding (portmap) works only locally

    - by Tag Wint
    There are four hosts hostA winXP hostB Win2003 hostC Linux RHEL hostD Linux RHEL hostA cannot connect to C and D directly, but B can hostA connects to hostB using VPN hostB and hostC belong to the same subnet1 hostD is in subnet2 From hostA I need to connect to hostC and hostD by SSH. Now I can do it as follows: 1.connecting from hostA to hostB by RDP logon and there: 2.start putty client. I'd like to omit step 1 and connect from A to C and D directly On hostB I have admin acoount and configure port forwarding as follows: netsh interface portproxy add v4tov4 listenport=N1 connectaddress=hostC_IP connectport=N2 netsh interface portproxy add v4tov4 listenport=N3 connectaddress=hostD_IP connectport=N2 netsh interface portproxy show all: Listen on IPv4: Connect to IPv4: Address Port Address Port --------------- ---------- --------------- ---------- * N1 hostC_IP N2 * N3 hostD_IP N2 Now from hostB I can connect to either C and D: ssh localhost:N1 ssh localhost:N3 from hostA ssh hostB:N1 works too, but ssh hostB:N3 DON'T I guess the reason might be different subnets, still have no idea how to fix it. What should I do?

  • Connecting to VPN via Proxy

    - by Rodrigo
    Hi, My company's VPN server is located in Netherlands, from my current location this is a really crappy place in terms of connectivity, connection keeps dropping, it's slow and keeps being reset during high traffic times. I have a dedicated server over USA which is able to connect to VPN server without this issues, connection is stable and fast. My question is, how do I connect to this VPN using a proxy running on my dedicated server? I'm on Windows 7 using a VM on XP to connect to the VPN. Thanks.

  • Robocopy to a drive connected to a wlan router fails

    - by Ville Koskinen
    I have a wireless router and an USB hard drive connected to it. Basic file access on the command line and Explorer works flawlessly after having set up some options on the router and mapping to some folders with net use k: \\ROUTER\Folder1 /user:MYLAPTOP\Me password /persistent:yes net use n: \\ROUTER\Folder2 /user:MYLAPTOP\Me password /persistent:yes Robocopy (and using SyncToy for that matter) to a network drive however fails: robocopy c:\Files k:\Backup /MIR /Z gives There is not enough space on the disk. 2010/01/05 09:52:11 ERROR 112 (0x00000070) Accessing Destination Directory N:\ Waiting 30 seconds... The error message is misleading: there is plenty of space on the disk and the folders I'm copying are small. The router is an ASUS WL-500gp with a standard firmware. I'd appreciate if someone would be able to explain what is causing the problem and, if possible, how to fix it.

  • forwarding packets from wireless nic wlan0 to another Wireless nic wlan1

    - by user179759
    I have two wireless interfaces wlan0, wlan1 I want wlan0 to be connected to the internet via a wireless router and I want wlan1 to be in AP mode acting as a router to give internet access to whoever connectes to it. So basically all packets coming through wlan1 should be forwarded to wlan0 = Router = Internet. That's including DNS/DHCP/etc.. [A]~~~~~(Wi-Fi)~~~~~~v [B]~~~~~(Wi-Fi)~~~> [me] ~~~~(Wi-Fi)~~~~~>[AP/Router]------->[internet] [C]~~~~~(Wi-Fi)~~~~~~^ Any idea how can I do this? ps: I tried using bridges but I always get 'operation not supported' using the brctl tool.

  • 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 !

  • Ubuntu 12.04 on VMware Player loses network configuration

    - by d4ryl3
    I've been having this issue for 2 weeks now with my VMware Player-hosted Ubuntu 12.04. I only use it for my LAMP stack. I've had no issues with it before until about 2 weeks ago when it almost always (once per day at least) loses its network configuration. On boot it shows: Waiting for network configuration... Waiting up to 60 more seconds for network configuration... Booting system without full network configuration... Then when I do ifconfig -a it doesn't show an IP Address and couldn't get online. The only resolutions I've found so far was either to reinstall VMware Tools or use the VMware Player installer and choose Repair. This is frustrating to me because even when the issue was resolved after doing either of the steps I mentioned, the IP Address gets changed. Then I'd have to update the Remote Configuration of my IDE (Netbeans) and my database manager. What could possible cause this? Please help. Thank you. Additional details: I'm using a laptop with Windows 7 and connected to the office WiFi, which is unrestricted as far as I know. Thanks again.

  • 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?

  • Can't get network bridging to work

    - by Antonis Christofides
    I'm trying to make network bridging to work on a Debian squeeze (I'm experimenting in order to make a QEMU/KVM virtual machine that will be visible to the outside network as if it were a distinct machine). The problem is that when I type brctl addif br0 eth0 then I lose connectivity to the network until I type brctl delif br0 eth0. More specifically, here's how my machine looks like before I do anything (essentially eth0 is listening on 147.102.160.153): root@laura:/home/anthony# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 8c:73:6e:db:1c:1b brd ff:ff:ff:ff:ff:ff inet 147.102.160.153/24 brd 147.102.160.255 scope global eth0 inet6 2001:648:2000:a0:8e73:6eff:fedb:1c1b/64 scope global dynamic valid_lft 2591848sec preferred_lft 604648sec inet6 fe80::8e73:6eff:fedb:1c1b/64 scope link valid_lft forever preferred_lft forever 3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN qlen 1000 link/ether 4c:ed:de:8e:44:d7 brd ff:ff:ff:ff:ff:ff 4: vboxnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 0a:00:27:00:00:00 brd ff:ff:ff:ff:ff:ff 5: pan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether ee:7c:88:59:d0:e8 brd ff:ff:ff:ff:ff:ff Now let me add the bridge: root@laura:/home/anthony# brctl addbr br0 root@laura:/home/anthony# ip tuntap add dev tap0 mode tap root@laura:/home/anthony# ip link set tap0 up root@laura:/home/anthony# brctl addif br0 tap0 Until here everything continues to work normally. Finally, I try to add eth0 to the bridge: root@laura:/home/anthony# brctl addif br0 eth0 At this point, I no longer have a network connection. If I try to ping something, it tells "Destination Host Unreachable".

(If there's another way to achieve what I want, I'm also interested.)

  • route lan traffic through wirless mifi

    - by Randall Blake
    I have a Windows 7 laptop accessing the internet through Verizon wireless MIFI configured as 192.168.1.1. It supports only 5 wireless connections, so I don't want to use up connections unnecessarily. That laptop has an ethernet nic which I have given a static IP of 192.168.0.5. Everything else on the 192.168.0.0 network acquires an address via DHCP from a DLink router whose address is 192.168.0.1. Also on that network are a printer, some network cameras, and a linux pc. The linux pc does not have a wireless card (and I don't want to buy one). The linux pc is located at 192.168.0.122. I can ping the linux pc from the windows pc. But I cannot access the internet from the linux pc. I can ping everything on the 192.168.0.0 network EXCEPT the ethernet card in the Windows PC. It seems as though my DLink router will not route requests to the 192.168.0.5 nic on the windows pc. My windows pc has a default route pointing to the 192.168.1.0 network. It also has a route telling it to route all traffic destined for the 192.168.0.0 network through the 192.168.0.5 interface. I have tried adding a default route to the linux pc to "gateway" 192.168.0.5, but that does not work. I have also tried adding a default route to the linux pc to the gateway 192.168.0.1 (the DLink router) but that will not give me internet access either (over the 192.168.1.0 network). I tried these two different routes at different times - I did not set them both at the same time. I suppose this is a simple problem to solve, but I cannot seem to solve it. How can I give internet access over the 192.168.1.1 MIFI to my linux pc on 192.168.0.122? Thanks EDIT: Additional Info Internet | | MIFI (192.168.1.1) (wireless) | | (192.168.1.3) (wireless) Windows 7 PC Dlink Router (192.168.0.1) ------------ (192.168.0.5) (wired) | | |linux pc (192.168.0.122) (wired) | |printer (192.168.0.100) (wireless) | |network cameras, etc (192.168.0.103) (wireless) Only the windows pc is multi-homed with a wireless nic that connects to the MIFI wirelessly, and an ethernet nic with a wired connection to the DLink router. (The DLink permits both wired and wireless connections.) I don't want to use Windows internet connection sharing because I believe it will set up the ethernet nic as a gateway on 192.168.0.1 and a DHCP server. I already have the Dlink performing that role and I don't want to change that if I do not have to. (The Dlink permits me to make DHCP reservations and I really like that feature. I don't want to lose it.)

  • IPv4 not enabled in Windows 7

    - by RidDeBakTiYar
    I have a Netbook with Win 7 Starter edition. I am not able to get IPv4 enabled/installed in the Netbook and hence not able to network/connect to Internet. It says "Limited access" when I check connections. It all began when my system crashed and I was not able to get thro beyond the boot screen. The system advice me to try repair with the original OS cd and I did the same. After that the Netbook has booted, but is not able to network. On a detailed study I found that the Network adapter has both IPv4 and IPv6 Protocols, but there are some differences. The IPv4 is not having the "Properties" enabled to configure, while the IPv6 is having "Properties" enabled. I have only a IPv4 Wired and Wireless at home and its not able to get the Netbook connected as it cannot I had tried uninstalling the Adapter to allow windows to automatically detect and install. Using the "netsh" command to uninstall and install, but not having any change in status. There is a option to "Have disk" under add Protocol, but I don't know how to give the standard IPv4 for installation (asking for *.inf). Any help in solving the issue will be very much appreciated

  • WHS - Windows Update Failure

    - by Kyle B.
    Clicking "Update Now..." inside my EX470 control panel for Windows Update produces the following error message: "Windows Home Server updates installation can not complete. Please try again later. If the problem persists, please restart the server." I have rebooted the server numerous times, and I have also used remote desktop to connect to the machine to perform the update this way, however the browser is unable to pull up http://windowsupdate.microsoft.com. This is very strange behavior because I am able to access all other sites (gmail.com, serverfault.com, etc). Would it be possible for someone to explain to me how I can check to see what is blocking the connection of this device, which apparently has a valid internet connection, to the Microsoft Windows Update site? note #1 Using the shortcut: %SystemRoot%\system32\wupdmgr.exe does not work either. It says "Connecting to 65.55.200.155..." but nothing ever happens. This is strange because all other sites seem fine. Also, I can connect to windowsupdate.microsoft.com on my local desktop so I know this is running as well

  • How to backup a networked drive?

    - by nute
    I have a networked drive (Iomega Media Drive). To be safe in case the drives crashes, I've decided to buy an additional networked drive (WD MyBook World). Now, how do I backup one onto the other continuously? The WD drive came with a backup software (trial version, they didn't say that when i bought it), however it doesn't allow me to select a networked drive, only local drives. How do I backup a NETWORKED DRIVE ONTO A NETWORKED DRIVE? Thanks

  • TIME_WAIT connections not being cleaned up after timeout period expires

    - by Mark Dawson
    I am stress testing one of my servers by hitting it with a constant stream of new network connections, the tcp_fin_timeout is set to 60, so if I send a constant stream of something like 100 requests per second, I would expect to see a rolling average of 6000 (60 * 100) connections in a TIME_WAIT state, this is happening, but looking in netstat (using -o) to see the timers, I see connections like: TIME_WAIT timewait (0.00/0/0) where their timeout has expired but the connection is still hanging around, I then eventually run out of connections. Anyone know why these connections don't get cleaned up? If I stop creating new connections they do eventually disappear but while I am constantly creating new connections they don't, seems like the kernel isn't getting chance to clean them up? Is there some other config options I need to set to remove the connections as soon as they have expired? The server is running Ubuntu and my web server is nginx. Also it has iptables with connection tracking, not sure if that would cause these TIME_WAIT connections to live on. Thanks Mark.

  • How To Fix Samba File Permission Issues in Mac OSX

    - by user1867768
    I've had this problem for a long time, here is the basics of it... I use a mixed environment of Windows 7/8 computers with Mac OSX Lion/Mountain Lion. Whenever a Windows computer creates a file on a SMB share on the Mac it no longer has group permissions, only the person who created or updated it can access it. My solution has been to go onto the Mac system and reset permissions for the entire directory structure then everyone can see it again. About the only thing on this that I can find was for OSX pre Snow Leopard that mentioned editing the SMB.CONF file to fix their particular problem (similar to mine, http://www.gladsheim.com/blog/2009/09/19/osx-leopard-and-samba-permissions/). The problem is that now Lion and Mountion Lion no longer have an SMB.CONF file (another web search pointed to the com.apple.smbd.plist (http://kidsreturn.org/?s=smb.conf) but it's an XML file now and I'm not clear on what should be done to THAT to fix the problem. So, short of me writing an Applescript to run every hour to fix permissions, does anyone know a solution to this very frustrating problem? Thank you in advance for any advice or solutions you can offer!

  • 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?

  • Accessing network shares on Windows7 via SonicWall VPN client

    - by Jack Lloyd
    I'm running Windows7 x64 (fully patched) and the SonicWall 4.2.6.0305 client (64-bit, claims to support Windows7). I can login to the VPN and access network resources (eg SSH to a machine that lives behind the VPN). However I cannot seem to be able to access shared filesystems. Windows is refusing to do discovery on the VPN network. I suspect part of the problem is Windows persistently considers the VPN connection to be a 'public network'. Normally, you can open the network and sharing center and modify this setting, however it does not give me a choice for the VPN. So I did the expedient thing and turned on file sharing for public networks. I also disabled the Windows firewall for good measure. Still no luck. I can access the server directly by putting \\192.168.1.240 in the taskbar, which brings up the list of shares on the server. However, trying to open any of the shares simply tells me "Windows cannot access \\192.168.1.240\share You do not have permission to access ..."; it never asks for a domain password. I also tried Windows7 native VPN functionality - it couldn't successfully connect to the VPN at all. I suspect this is because SonicWall is using some obnoxious special/undocumented authentication system; I had similar problems trying to connect on Linux with the normal IPsec tools there. What magical invocation or control panel option am I missing that will let this work? Are there any reasonable debugging strategies? I'm feeling quite frustrated at Windows tendency to not give me much useful information that might let me understand what it is trying to do and what is going wrong.

  • Browsing Playstation 3 from Ubuntu Box

    - by zfranciscus
    Hi, My Goal here is to be able to transfer files from my Ubuntu 10.04 box to my PS3 over a wireless network. My PS3 and my Ubuntu Box is on the same home network. These are some stuff that I tried: I can't see my PS 3 from 'Places ? Network' nor other computer that is running on windows. I am still puzzled by this fact. I have not tried ping-ing my PS3. I'll try that later today and post the result in the forum I install PS3MediaServer (http://code.google.com/p/ps3mediaserver/). Someone in the PS3 chat forum (http://www.ps3chat.com/playstation-3...lp-please.html) claims that it will enable your ubuntu box to browse PS3. So I downloaded PS3MediaServer, and ran the software. The status tab keep showing "Waiting ...". It seems that PS3MediaServer can't find my PS3. Some how I feel that 1 and 2 are related somehow.Perhaps that there is something wrong with my Ubuntu network settings that is preventing my ubuntu box from looking up other device on the network. I can go to the Internet fine, but I can't see other device on my network. Does anyone have any experience in this area. I would like to hear your experience and perhaps some solution. Any kind of hints or help will be greatly appreciated. Cheers

    We've got about 3 procurves linked up with about 5 linksys srw248g4p. Pinging between the Procurves I get ping time between 1-2 ms and pinging between the linksys the ping time are averaging 40 ms. I have evening tried pinging between two linksys switches that are connected to each other directly using the GB ports. There have no modification done to the switches and the firmware seems to be uptodate. Any suggestions would be appreciated.

  • 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

  • Draytek Vigor 2820 static IP's

    - by dannymcc
    I have a Draytek Vigor 2820 router which is connected to our ADSL provider (British Telecom, BT). We currently have one static IP address which is accessible from anywhere outside of our network and points at a simple web server on port 80. We have just been given 5 more static IP addresses which I would like to point at five servers that have static IP's. As an example: Current static IP - 80.123.123.123 New Static IP's - 100.100.100.100-105 Server IP's - 192.168.1.129-133 I have confused myself completely between NAT addresses, static routes and WAN IP aliases.

  • Does using cat5e cables yield any disadvantages in combination with cat6/cat6a network?

    - by agent154
    If I were to have a fully compliant cat6 or cat6a network running through my walls... that is to say, wires and jacks... What would be the concequence of plugging a cat5e wire into one of the jacks? I'm assuming that it would still run at cat5e standards, but obviously not cat6/6a standards because the whole connection is not cat6. I only ask because it seems silly to me to make a bunch of cat6 patch cables for connections that don't really matter, like standard desktop computers and other equipment. Or will doing so hamper the whole network?

  • How do I tell ubuntu to send traffic to a single IP through eth6?

    - by flashnode
    I want to ensure that all IP traffic going to 172.16.60.62 uses eth6. Please provide complete commands because my linux-fu is rusty. The host is running Ubuntu Precise 12.04 user@host:~$ ifconfig eth3 eth3 Link encap:Ethernet HWaddr 00:e0:81:72:fe:c9 inet addr:172.16.60.122 Bcast:172.16.60.255 Mask:255.255.255.0 inet6 addr: fe80::2e0:81ff:fe72:fec9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:128500 errors:0 dropped:0 overruns:0 frame:0 TX packets:29082 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:67524823 (67.5 MB) TX bytes:2217634 (2.2 MB) Interrupt:71 Base address:0x6000 user@host:~$ ifconfig eth6 eth6 Link encap:Ethernet HWaddr 00:60:dd:47:81:35 inet addr:172.16.60.61 Bcast:172.16.60.255 Mask:255.255.255.0 inet6 addr: fe80::260:ddff:fe47:8135/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:9000 Metric:1 RX packets:109610 errors:0 dropped:0 overruns:0 frame:0 TX packets:109388 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:10785630 (10.7 MB) TX bytes:10754350 (10.7 MB) Interrupt:70 user@host:~$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 172.16.60.1 0.0.0.0 UG 0 0 0 eth3 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth6 172.16.60.0 0.0.0.0 255.255.255.0 U 1 0 0 eth6 172.16.60.0 0.0.0.0 255.255.255.0 U 1 0 0 eth3
