  • Failed pinging a LAN card of the server from the client using shared internet connection

    - by bobo
    The server (Windows XP Pro SP3) has two LAN cards (LAN card A and B) and is connected to the internet using ADSL. The ADSL connection is shared to LAN card B using Internet Connection Sharing. The client (Windows XP Pro SP3) has one LAN card, and is connected to LAN card B of the server so that it has access to the internet. The IP address on the LAN cards are defined as follows: Server: LAN card A: 192.168.0.3/24 (manually defined by me) LAN card B: 192.168.0.1/24 (manually defined by Internet Connection Sharing) Client: LAN card: 192.168.0.123/24 (assigned by DHCP) Default gateway: 192.168.0.1 From the server, I can ping 192.168.0.123 successfully. From the client, it can access the internet without any problem. I can also ping 192.168.0.1 successfully but for 192.168.0.3, it failed with the Request Timeout error message. Why did the ping fail, and what should be done to make the ping possible? (all firewalls have been turned off.)

  • Cloudstack virtual machines can't communicate with virtual routers when they are on different hosts

    - by Jorge Suárez de Lis
    I'm using Cloudstack 2.2.14 on a Ubuntu 10.04 set of hosts, and I have a problem on my setup. I have two hosts running. When a virtual router is created on host 1 and a virtual machine using that virtual router is created on host 2, or vice versa, I have no connectivity at all on the virtual machine. First of all, I have to setup the network manually on that virtual machine -usually DHCP is working, but not here-. Then, I can't ping to the virtual router from the virtual machine or vice versa. When both virtual router and virtual machine are created on the same host, everything works! Maybe those packages are being filtered somehow? I have no clue on how to proceed. Both hosts can communicate directly outside the virtualization.

  • why would you create two different subnets on the same physical network?

    - by xirtyllo
    I'm working at a messy location, one of the strange (for me) things is that on the same physical network there are two different subnets. Specifically some computers will have 10.0.0.0/24 and some others will have 172.16.0.0/24. There is only one DHCP server, which gives IPs on the 10.0.0.0/24 range, and there are two internet gateways, one with IP 172.16.0.1 and one with IP 10.0.0.1 . To give an example, I can easily swap one PC from one subnet to the other just by changing its IP and gateway settings. I am trying to imagine why they created the network this way, and which may be the possible advantages and/or drawbacks of having two different subnets on the same physical network. Any thoughts?

  • How do I configure custom routes when an interface is configured?

    - by ManicDee
    Other Superuser questions have addressed the issue of adding custom routes to access e.g.: multiple networks of a corporate network through one interface, while accessing the Internet through another interface. So assuming that I have a script to add specific routes when en0 is configured, and a separate script to add specific routes when en1 is configured, is there some way I can trigger those scripts to run automatically when Mac OS X/Darwin starts and configures those interfaces? Back in my Linux days, it was possible to add an option in /etc/network/interfaces along the lines of: iface eth0 inet dhcp up /usr/local/sbin/eth0-routes-up Is there something similar for Mac OS X?

  • Windows 7 recognises the wrong router.

    - by Henry
    I have a cable router connected to my cable ISP. On the LANs are 4 computers, one of which is a dual boot XP/Win7 machine. I was given an ADSL wireless router which I connected to one of the LAN sockets on my cable router. I don't have an ADSL connection. All the machines connect correctly, some wirelessly, when my dual boot machine is in XP or off. However, when I go into Win 7 on that machine it finds the ADSL router and wants to connect through that (there's no ADSL connection) instead of my cable router and modem. I've turned DHCP off on the ADSL modem and even tried bridging its connections but neither of these have any effect. To get 7 connected, I have to either disconnect the ADSL router, or switch it off. Remember, the SAME computer on the same LAN works perfectly with the same router connected in XP! How then, can I get Win 7 to recognise the correct router?

  • Vmware sphere setting up external network

    - by Tom Beech
    I've just setup vmware vsphere 5 on a remote server (rented dedicated server). I've added my first VPS (centos 5.8) barebones. It's not finding any IP (internal or external) on boot. I've had an extra external IP assigned to my server that I wanted to use on the VPS. I tried editing the eth0 config and adding the IP in there and turning off the DHCP, but it can't find any IP or ping google or do any networking type things. How do I route the IP to my VPS so I can access it remotely?

  • Configuring a Genius GW-7200 Access Point

    - by alex
    I came across an access point we had a few years ago. I'm now trying to get it set up to work on our network. here are a couple of pictures: http://twitpic.com/194u06/full http://twitpic.com/194u0v/full I have plugged this into our network via the network port on the back. I set up a DHCP reservation, based on the MAC address on the back of the access point, however I cannot ping it, nor access the web interface. I've held down the reset button for 10 seconds, to see if that would do anything. Google doesn't come up with anything on the matter :-(

  • Linux (Kubuntu 9.10): Strange DNS problem [seems to be IPv6 issue]

    - by Homer J. Simpson
    Hi, I'm experiencing strange problems with my Kubuntu 9.10 when doing DNS requests from various applications. The requests are extremely slow, so loading any pages in Firefox or Konqueror, doing package installations in Kpackagemanager and other apps is really painful, while for example Opera doesnt have any problems, and ping is normally fast as well for DNS pings. I checked the proxy settings of both the used applications as well as of the general system and there are none, so to me it doesn't seem as there was something inbetween.. Does anybody have an idea on what to check for possible problem sources or how to solve this ? I'm behind a DSL home router which does the DHCP (and works well with my other computer). Any kind of advice would be really helpful. Edit: It seems to be some kind of IPv6 problem, as I could get it to work by disabling IPv6 explicitly in Firefox. Is there a general solution to this ?

  • Free IP address management software

    - by TiFFolk
    We are choosing a system for managing our IP address space. So we are looking for a special free software like IPPlan. So what we have nowadays: Ipplan (Does not support IPv6) SolarWinds IP address tracker (IPv6 support unknown ) IP module of The NOC Project (BTW, take a look of it, seems to be very promising project) (IPv6 support unknown ) phpIP (Does not support IPv6) IP management from RackTables (Does not support IPv6) Do you know about any other special software, like written above? But: No Wiki No DNS No DHCP No spreadsheet Software should provide: Clear view of available addresses Detail listing of all addresses by subnets/search pattern/owners/additional info It must support adding additional info like owner of IP, domain-name, contacts, etc Multi user support Easy interface Software has to be specially written for address management. Scalability Any OS: win, lin, sol, web

  • Broadcast UDP over VPN

    - by ibmz
    I have OpenVPN configured and have 5 dd-wrt router clients. I would like the machines on those routers to be-able to UDP Broadcast across all 5 networks. I cannot bridge the interfaces(to my knowledge) because each router needs to be able to operate on its own should the VPN connection die (dhcp needs to work). currently each router has its own /24 (eg 192.168.1.x) network. Is there a way to use IPTables to mangle the udp and forward them to all VPN Clients? To summarize i need 1)to UDP broadcast to all routers and their clients 2)for all routers to be able to operate independently should the VPN go down

  • How to find the static ip address of my router? [migrated]

    - by Wintermute
    I bricked my Linksys WRT54GS router when trying to change the firmware on it from dd-wrt to open-wrt. In order to unbrick it, I need to be able to do an ftp transfer to it. The problem is that it isn't using DHCP addressing and I can't just use the default ip address of 192.168.1.1. I have to use the ip address it was set at before it got bricked. The problem is I forgot what that number was. Is there some program or script that can find it out?

  • static routes, cisco ASA, remote locations

    - by Jeff
    192.168.3.1(ASA) - 192.168.2.1(ASA) - ( internet ) - 192.168.1.1(ASA) DomainController, FS, Exchange 192.168.0.1(ASA) - above is a rough idea what my network setup looks like. each internal ip (192.168.x.x) is located behind an ASA. Each location has a different gateway for the internet. They all talk to the 192.168.1.1 network for dns, dhcp, dc, exchange and so on. They can only see the 192.168.1.1, they can not see each other. In my Static Routes on my 192.168.1.1 ASA, should i have them configure as follows? example: 192.168.x.x 255.255.255.0 Locations_Internet_Gateway_IP OR 192.168.x.x 255.255.255.0 Main_Locations_Internet_Gateway_IP not sure which configurtation is correct, thanks in advance for any help!

  • NFS-Root not working when booting over PXE

    - by Randy
    I am desperately trying to get a diskless client running over PXE-Boot using a NFS-Share as a root file system. I did this before some years ago but for some reason I am stucked at this since days. The TFTP-Server itself is running fine and booting a netinstaller works also fine. The kernel and initrd are loaded also but the bootprocess stops with this (screenshot) kernel panic. I'm using the squeeze standard i386-Kernel and I have prepared the initrd with this config: MODULES=most BUSYBOX=y KEYMAP=n COMPRESS=gzip BOOT=nfs DEVICE= NFSROOT=auto I also tried MODULES=netboot with the same outcome. My PXE-configuration looks like this: LABEL linux KERNEL diskless/debian-default/vmlinuz-2.6.32-5-686 APPEND root=/dev/nfs initrd=diskless/debian-default/vmlinuz-2.6.32-5-686 nfsroot=192.168.140.2:/storage/nfs-boot-images/default-squeeze ip=dhcp rw Furthermore I have captured the network communication of the client via tcpdump and learned that the client isn't even trying to connect to the NFS-share. Does anybody has got an idea what is going wrong here?

  • On a router, how do I block wan access for a particular machine without blocking its access to the local network?

    - by HappyEngineer
    On my tp-link TL-WR1043ND router I want to prevent a particular machine from having access to the WAN while still allowing that machine to access other machines on the LAN. My assumption is that I need to do something in the "Access Control" section, however the problem is that it wants an ip range or domain name for the target of the rule. The router uses DHCP to get an address from the WAN, so I don't have any guarantee what the ip address of the wan will be. If the answer is that it's not possible with this router, could someone describe how to do it using OpenWRT instead?

  • Setting up D-link AP2100 as a repeater

    - by Mersan
    Hi, I have two D-Link AP2100, one is connected to a switch (with cable). The second one I would like to use as a repeater, using the WiFi connection to the first and not connected to the switch. Does anyone know first if this is possible, and second and most important, how does one do it. I have tested to set the second AP in repeater-mode, and it is connected to the first, I have full strength to the second one, but I'm not receiving any IP från the DHCP-server, so no access out. Any ideas? /Mersan

  • Windows 7 / Windows Vista won't connect to 802.1x RADIUS Server

    - by Calvin Froedge
    I've deployed Radius and have no problems connecting with TTLS, PEAP, or MD5 using linux, mac, and windows xp. For Windows 7 and Vista, I'm never prompted with the dialog box to enter username & password after configuring 802.1x support on the client. Steps taken: Enabled Wired Autoconfig in services.msc Set to use PEAP Set to require user authentication When I enable the network connection it says "Trying to authenticate" then fails with no error log / message given. The radius server gives no indication that there was ever a request (no Access-Reject - the client simply never tries to authenticate). On the windows 7 client, I can see that the DHCP server does not assign an IP to the client when 802.1x is enabled on the client (though it does when it isn't). How can I debug this further? Has anyone else run into a similar situation? My radius server is freeradius on Ubuntu 11.10.

  • Can't connect to Apple Time Capsule in home network using Home Plugs from Win 7 Machine

    - by Eugene
    I have the following home network setup with subnet 255.255.255.0 but recently moved my time capsule to a different location when I added a third Home Plug and can no longer ping or map a network drive to it from the Windows 7 Machine. However using Airport Utility on the Windows 7 machine I can manually configure the Time Capsule. Using a Macbook on WIFI Network 1 or 2 - I can backup to the time capsule, so its accessible via both the router wifi network and the time capsule wifi network. The Time Capsule is set to BRIDGE function - ie no NAT or DHCP server enabled. Any bright sparks out there that can help diagnose the problem? Router (192.168.1.254) WIFI Network 1 | | |---- Home Plug one |---- Home Plug Two | |---- Computer A Windows 7 (192.168.1.160) | |---- Printer (192.168.1.69) |---- Home Plug Three | |---- Apple Time Capsule (192.168.1.150) WIFI Network 2 |---- Smart TV (192.168.1.70) | |---- Apple TV (192.168.1.4)

  • Windows 2003 shutdown instead of reboot

    - by The_cobra666
    Hi all, I've got a very strange problem. On the net I can only find problems with Server 2003 pc's, that reboot instead of shutting down, but in my case... (go figure) it does the opposite. When I choose to reboot, the system shutdown. Yes I am sure I used the reboot button. It happens via start == reboot and it happens when clicking on the reboot button when the update's have been installed. Nothing changed to the system's hardware. Only update's have been installed on the system. I did notice something odd in the logs when rebooting: Description: Timed out sending notification of target device change to window of "C:\WINDOWS\Explorer.EXE" KB: http://support.microsoft.com/kb/924390 They talk about a removable drive, but in my case, it's explorer.exe :s it appears 4 times. OS: Windows Server 2003 R2. Services: AD, DNS, DHCP, WSUS. Thanks in advance! Greetings from Belgium Shane

  • firehol (firewall) with bridge: how to filter

    - by Leon
    I have two interfaces: eth0 (public address) and lxcbr0 with 10.0.3.1. I have a LXC guest running with ip 10.0.3.10 This is my firehol config: version 5 trusted_ips=`/usr/local/bin/strip_comments /etc/firehol/trusted_ips` trusted_servers=`/usr/local/bin/strip_comments /etc/firehol/trusted_servers` blacklist full `/usr/local/bin/strip_comments /etc/firehol/blacklist` interface lxcbr0 virtual policy return server "dhcp dns" accept router virtual2internet inface lxcbr0 outface eth0 masquerade route all accept interface any world protection strong #Outgoing these protocols are allowed to everywhere client "smtp pop3 dns ntp mysql icmp" accept #These (incoming) services are available to everyone server "http https smtp ftp imap imaps pop3 pop3s passiveftp" accept #Outgoing, these protocols are only allowed to known servers client "http https webcache ftp ssh pyzor razor" accept dst "${trusted_servers}" On my host I can connect only to "trusted servers" on port 80. In my guest I can connect to port 80 on every host. I assumed that firehol would block that. Is there something I can add/change so that my guest(s) inherit the rules of the eth0 interface?

  • Virtual DNS recommended setup...

    - by luison
    Hi. We are new to virtualization which we are setting up with Proxmox VE (OpenVZ + KVM). I am a bit lost about the recommended DNS forwarder config specially in the OpenVZ (Virtuosso type) of enviroiment. Our intention was to have a small dnsmasq running in one of the VM acting as backup DHCP server and serving our in-office local addresses (and PCs) by an additional resolve.conf file which dnsmasq supports, but I've read that all VM should share DNS pointing to the host machine in which case it would make more sense having it there. My problem is that I would like to have as least as possible apps in the host so a reinstall of the environment (porxmox ve) and a machine restore can be as quick as possible. Does anyone have a similar setup? Does it make sense to have the 1st virtual machine running the local dns forwarder? Also... dnsmasq seems to want to have root permissions when running on an OpenVZ container... are there any work arrounds anyone knows for that.

  • Using VMWare Workstation, to convert a physical Win2008 into a templtae

    - by SndLt
    I'm new to VMware and despite having read the documentations, I'm having trouble. I'm using VMware workstation Stand-Alone package to turn a physical Win Server 2008 R2 into a usable VM appliance. The source and destination part is getting me here. It seems using keyword "localhost" doesn't cut all the way through. Does the shared folder have to be in my local drive for that matter? For ip, am I using the simple private IP that my nearest DHCP has given me? But what if I have more than one interfaces that have two or three different private ip addresses? Thanks.

  • Wireless network unavailable, no networks found after Windows update

    - by jacobsee
    Old Dell Inspiron 8200 laptop with Linksys Wireless G network adapter card (WPC54G v2). Wireless connection was working fine. Then I ran a bunch of windows updates, I think the last one was the recent .NET 3.5 service pack update. Now wireless networks won't connect. Using windows to manage wireless, no networks show up. I'm typing right now on another laptop where wireless is working fine. I've restarted router & Dell laptop several times. Tried to Repair wireless connection and refresh network list. Also restarted DHCP and WZC service, all to no avail. I then uninstalled .NET 3.5 SP (don't remember number) and .NET 3.0 SP2. I don't remember all the windows updates that I just ran because I haven't used this laptop in a while so had to catch up on some updates.

  • Can't ping some IP addresses in the same subnet (LAN) Windows 2011 Server

    - by Ricardo
    Hi I’m running in Windows Small Server 2011 server standard (192.168.1.108), it’s my dhcp and dns server too, but suddenly all other users can’t get internet. My gateway is 192.168.1.1. After a lots of tested I can saw that my server can’t get into the router (192.168.1.1), and also into some others computers, but some other computers answer the ping command. In fact the same computer with the IP 192.168.1.9 didn't answer, but with the IP 192.168.1.63, it response! I have no routers, firewall, vlans or anything that disallow the traffic between computers, in fact when I changed the server IP address (192.168.1.109), I be able to ping the other computers and gateway, but if a back to the 192.168.1.108 the trouble comeback. I hope you can help me with this issue Ricardo

  • Should my servers boot from VHD?

    - by tony roth
    I've been testing native vhd boot on several servers. It seems to be pretty transparent in terms of deployment and with my seat of the pants testing I have not noticed any difference in performance. The main reason that I want to boot vhd is due to their transportablility between different hardware and to hyper-v servers. the following roles will be installed. dfsr dhcp iis application server dc <- haven't tested this yet but see no reason why it won't work. With the above low impact (in terms of performance) roles do you thing booting from VHD is appropriate. thx

  • Removing Exchange 2010 and SBS2011 gracefully after migration to Server 2008 Std R2

    - by user145275
    We have recently completed a server replacement for a customer. They had SBS2011 using Exchange 2010. They now have Server 2008 Std R2 and Google Apps email. We have migrated the DHCP, DNS, Filserver and all 5 FSMO roles to the new 2008 R2 server (today). During the grace period for SBS2011 we intend to decomission the old server completely. Previous experience would suggest uninstalling Exchange 2010 then demote SBS2011 then remove from the domain and switch off. Can I simply demote SBS2011 without removing Exchange? Can't really find any walkthroughs on this. My concern is that if we simply turn off SBS2011 the AD is left in a mess with legacy Exchange objects making any potential reintroduction of Exchange difficult in future, plus I want to do it the right way!
