• Separate 2 networks with 1 Windows Server

  - by SamuGG

  The situation is: I have 1 router 192.168.1.1, 1 switch, 1 windows server and a basic LAN of devices accessing it. I need to split into 2 separate LANs with full Internet access each, but isolated from each other. Given that, the server is a Windows Server 2008 R2 with 2 NICs: NIC1: 192.168.1.2 NIC2: 192.168.2.2 The router has no dhcp configuration. Please, can anyone explain gracefully, step by step, what do I need to do? What would be the 2 NICs full configuration? What services do I need to install? I don't want devices on either network to see devices on the other network, they must be completely separate. I guess I'm missing the routing procedure step, but I have no idea how is that done. For example: tell the server that devices with gateway 192.168.2.2 must send traffic for internet to 192.168.1.1 router. Thanks in advance.

• ASUS WL-500gP v2 network between two local machines

  - by Epsiloncool

  I have two windows XP machines in my home networks, connected with ASUS WL-500gp V2 which also used as internet router. Problem is: while I have both computers normally goes to internet (used DHCP, static routes is ON, routing table is empty, operation mode is Home Gateway). I see both computers listed on the Network Neighborhood on 1st computer (wired to router), can enter to my own computer, but can not enter to other. I see only one computer (2nd) on the Network Neighborhood on 2nd computer (connected thru Wi-Fi), can enter to itself, getting error when trying to enter 1st computer address in address line (like \My1stComp). What is the problem? I totally crazy founding problem about 3 months.

• Why can't my FreeBSD 6.1 (vmware player client under Win7) do DNS in Bridged mode.

  - by Walter Stickle

  I have a 64-bit FreeBSD 6.1 client, running under Windows 7 (64-bit) via VMWare player 3.0, with networking set to bridge mode. DHCP goes fine on boot... I get correct adress/gateway/nameserver info... I have good connectivity to the world in that I can ping any host I can name by IP addr, (including both of the nameservers in resolv.conf,) ...but I can't resolve any names. Inside the Windows box, the network interface has VMWare Bridge Protocol enabled, and the windows side of things has full connectivity. dig replies with: ;; connection timed out; no servers could be reached ...even if I use "dig @server_ip_addr" to point it at a pingable, working nameserver If I set VM networking to NAT mode, I can get outbound connectivity (with happy DNS) but, of course, can't do INBOUND connectivity, which I need. Thoughts?

• Server 2012r2 VPN DNS

  - by Tyron Gower

  Have an issue where onsite clients cannot resolve VPNusers. but VPN users can resolve onsite machines. example. USER! uses LAPTOP1 USER1 connects to VPN gets internal IP address of 10.243.0.200 USER1 pings SERVER1 - resolve to ip and gets reply USER1 RDP into SERVER1 (inside VPN) USER1 pings LAPTOP1 from SERVER1 resolves to ip address last assigned by DHCP (10.243.0.139) ping fails USER1 pings 10.243.0.200 from SERVER1 gets reply. Running Server 2012r2 It is a domain controller, DNS and VPN server. VPN is just configured with basic default settings. All VPN users have static IP setup in AD. Not sure where to go from here.

• how to design LAN connectivity between private and corporate ?

  - by maruti

  there is a bunch of servers connected to shared storage in a private LAN (10.x.x.x). this privateLAN is managed by a windows server (DHCP, DNS and directory services). how can these hosts be accessed from outside of this privateLAN? Eg. Remote desktop. can the NIC2 on each of the hosts be connected to the other public LAN (compromising speed or security? what are improtant considerations: additional hardware? like switches? routing&DNS software?

• How can I solve Windows PPTP VPN issues?

  - by Robin M

  I'm having persistent problems with Windows PPTP VPN connections. The VPN appears up whilst the tunnel won't transfer traffic (ping to a remote IP within the VPN works for a while, and then fails). The client receives routing information via DHCP. When the connection fails, the routing table is still correct so I don't think it's a routing problem. My internet connection is via an ADSL2 line. There's software to deal with PPTP problems, like TunnelRat, but I don't want to install v1.1 of the .NET framework and I'd rather get to the bottom of the problem (I have multiple VPN connections and some are more unreliable than others). What can I do to get to the bottom of this? Alternatively, what can I do to keep the connection alive?

• Can i change the subnet on the vpn side of a server without having to change its whole lan (to avoid collission)

  - by Gusty

  Ohai, ive got a xp server with a client connecting via VPN. Problem (as we all know) is that sometimes the subnets clash. Instead of changing the whole server network every time this happens, cant i just have the server appear to have a different subnet to vpn clients? I have no interest in accessing other computers than the server on its LAN. I tried just turning off automatic dhcp in the servers vpn settings and changed it to 172.31.255.x. The client gets the address assigned alright and it can ping 172.31.255.1 but i cannot ping the server name (because the dns on the clients vpn connection points at 192.168.0.1?) wisdom? PS everything worked until the client hit a network with the same subnet as the server lan. thanks

• Two NICs, one server.

  - by kobrien

  I have two NICs on a fresh install of Ubuntu 10.04 LTS. Both are config'd be dhcp. Both cards are on the same lan with same gateway. everything about the cards is the same except the IPs they get, which is what I want. What I'm trying to achieve is having both NICs operational at the same time. Currently when the server boots, it activates both NICs, but the server can't resolve any domains. If I ifdown one of them and bring it back up, the server is able to resolve domains, but the NIC I bring up won't respond to any traffic. Any ideas?

• parallel vms in VMWare Server - how to configure network so they can ping each other?

  - by IronGoofy

  I'm using VMWare Server (currently on Version 1.0.7) and have two VMs that I would like to run at the same time. However, I'm having problems in setting them up so they can ping each other. I've configured them to use 'Bridged' networking. They both obtain an IP address from the DHCP server on my network, but after that they can't ping each other. It seems that only the first one has a functioning network connection (I can ping it from the host machine and Internet connection works), but the other one does not. If it helps, both VMs are running XP SP 3. Any ideas? Thanks!

• I want to "image" 40+ laptops quickly...i welcome suggestions on reliable software

  - by Joldfield101

  I often have batches of laptops/PC's to re-image and have tried various methods, but each of them has been problematic and often take more time to troubleshoot than it would have been to image them individually! For example, i have tried to use ghost - i installed ghostcast server on my laptop but the clients never seem to boot to LAN successfully, or it takes an hour to get everything sorted (drivers, LAN, DHCP etc etc). I want a reliable tool that makes imaging quick and easy - and i don't mind paying for it if it's going to work (but obviously free = always good!)

• What protocols will/are ISPs use for IPv6 deployment?

  - by rbeede

  Currently ISPs deal out addresses via DHCP for IPv4 dynamic (single) addresses. What protocol will/are ISPs going to use for IPv6 when they can hand a customer an entire /64 (or /48 if they are nice) block? DHCPv6, RA? For ISPs that support true end-to-end IPv6 will they provide gateway devices (similar to cable modem or true DSL bridges for example) that receive border information for that specific customer? I'm just trying to get an idea of how your common residential service customer will have to configure things in an IPv6 Internet (whenever that comes). Will it be something customers are expected to statically configure on their home wireless router? Today with IPv4 I do it like this: Modem (bridge) passes public IPv4 obtained via DHCPv4 from ISP to second device (wireless router). It in turn has its own DHCPv4 service it provides on the internal lan.

• Windows XP clients do not update server 2008 DNS forward lookup zone.

  - by whatsisname

  I have a Cisco 5505 working as a DHCP server, and a server 2008 DNS server running an AD domain. I am having problems with all XP computers not updating the forward lookup zone. The reverse lookup zone updates are working. Windows vista and 7 computers update just fine. Additionally the DNS server accepts both secure and non-secure updates. When people are connected through the Cisco's VPN, they cannot resolve to any machines that have reverse lookup zones, but they can resolve entries in the forward lookup zone. I have tried ipconfig /registerdns, but the forward lookup zone entries for the XP clients are not being populated. How can I get the XP Dynamic DNS client to make the updates, or what can I do to debug what's going on? Thanks

• How do I transform a LAN subnet to another? (VPN)

  - by Krishath

  I've set up a VPN with a LAN behind it. VPN : 10.2.1.X LAN : 192.168.1.X When I connect from outside where the router via DHCP assigns me a similar IP to my "original LAN" (192.168.1.X) everything starts to be messed up. I can't route my traffic through the VPN and (obviosly) I can't reach my "real" LAN behind my VPN. How can I always reach my LAN? I thought that I can fake my LAN subnet to something like "10.2.2.X" to those PCs out of my VPN but in this way my VPN server should translate 10.2.2.X to 192.168.1.X (locally).[Is this S/D-NAT?] Is this possible? How can I accomplish that? Thank you very much!

• Port forwarding with router in bridged mode

  - by jipje44

  let say R1 and R2. R1 is in bridged mode and connected to R2. R2 is a dhcp server. To R2 is an internet camera connected. When i am on R2 and i do enter the ip of the camera then it will work without a problem. However i want to acces the camera from the outside. So in R2 i forwarded a port (done this one other networks without problems). However I can't connect from the outside. Can R1 blocking the port? I cant log in on R1 as long as it is in bridged mode.

• EC2 Windows 2008 VM import Not Working

  - by remack

  I am trying to upload a Windows 2008 SP2 server image to Amazon EC2, but once the process is complete, I can't connect to it. I had ops export a VMDK from our datacenter. The image appeared to have a fixed IP, so I loaded it in VMWare player and enabled DHCP. I uploaded it following amazon's instructions: http://aws.amazon.com/ec2/vmimport/ I start the new instance and try to RDP to the public DNS; connection fails. My two thoughts are: Loading it in VMWare player messed it up somehow, since the instructions say use an ESX image. The image they made me had the wrong network adapter type. The image has an Intel(R) PRO/1000 MT adapter using the E1G60I32.sys driver.

• Ubuntu 12.04 LTS Wireless Asus USB-N53 (rt3572sta) driver installation issue

  - by Jake Thompson

  My purchase of the Asus USB-N53 just came in today and I spent several hours Googling and researching drivers for this device. When I first plugged the device in it connected fine to my open system, WEP, DHCP configured access point. I opened Google Chrome and a few pages loaded, everything seemed fine. 30 seconds later... Boom! It disconnected and showed attempts to reconnect and asked for the WEP key and just showed a state of infinite connection time until it asked me for the password again. I'm using amd64 (64 bit Ubuntu desktop 12.04 LTS) The official driver can be found here although I had no luck with it. lsusb: Bus 003 Device 002: ID 0b05:179d ASUSTek Computer, Inc. uname -a Linux Jake 3.2.0-31-generic #50-Ubuntu SMP Fri Sep 7 16:16:45 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ----------------------------------------------------------------------------------Solved: I must of done something wrong when I originally installed the latest drivers from the chipset manufacturers website. I tried reinstalling and did modprobe rt3572sta and waited maybe 10 minutes??? and I connected then I rebooted and everything seems to be working so far. What I did do before hand is unplug the device and typed into the terminal (once for every source I attempted to install): cd '<directory of the driver source>' make uninstall make clean Then I went into the 2.5.0.0 directory and installed that with make make install Then I typed modprobe rt3572sta This was all in superuser.

• Begin the Clone Wars Have!

  - by Antony Reynolds

  Creating a New Virtual Machine from an Existing Virtual Disk In previous posts I described how I set up an OEL6 machine under VirtualBox that can run an 11gR2 database and FMW 11.1.1.5.  That is great if you want the DB and FMW running in the same virtual image and it has served me well for some proof of concepts and also for some testing of different JVMs.  However I also wanted to run some testing of FMW with the database running on a separate physical machine.  So in this post I will show how to take a VirtualBox image and create a new image based on the disks from that original image. What are my Options? There is more than one way to skin a cat, or in this case to create two separate VMs that can run on different hardware.  Some of the options include: Create new virtual disk images for each new VM. Clone the existing disk images and point the new VM at the cloned images. Point the new VM at the existing snapshots. #1 is too much like hard work, install OEL twice, install a database again, install FMW again, run RCU again!  Life is too short! #2 is probably the safest way of doing things.  VirtualBox allows you to clone a disk image for use in a separate machine.  However this of course duplicates the disk and means that it is now occupying 3 times the space, once for the original disk and twice more for the two clones I would need. #3 is the most space efficient way of doing things.  It does mean however that I can only run the new “cloned” images if I have access to the original image because that is where the base snapshots reside.  However this is not a problem for me as long as I remember to keep all threee images together.  So this is the approach we will follow. Snapshot, What Snapshot? As we are going to create new virtual machines based on existing snapshots we need to figure out which snapshot to use.  We do this by opening the “Media Manager” from within VirtualBox and moving the mouse over the snapshot images until we find the snapshots we want – the snapshot name is identified in the “Attached to:” comment.  In my case I wanted the FMW installed snapshot because that had a database configured for FMW alongside the FMW software.  I made a note of the filename of that snapshot (actually I just noted the first 5 characters as that was all that was needed to uniquely identify the snapshot file). When we create the new machines we will point them at the snapshot filename we have just checked. Network or NotWork? Because we want the two new machines to communicate with each other when hosted in different physical machines we can’t use the default NAT networking mode without a lot of hassle.  But at the same time we need them to have fixed IP addresses relative to each other so that they can see each other whilst also being able to see the outside world. To achieve all these requirements I created two network adapters for each machine.  Adapter 1 was a standard NAT mapping.  This will allow each machine to get a dynamic IP address (10.0.2.15 by default) that can be used to access the external world through the VBox provided NAT gateway.  This is the same as the existing configuration. The second adapter I created as a bridged adapter.  This gives the virtual machine direct access to the host network card and by using fixed IP addresses each machine can see the other.  It is important to choose fixed IP addresses that are not routable across your internal network so you don’t get any clashes with other machines on your network.  Of course you could always get proper fixed IP addresses from your network people, but I have serveral people using my images and as long as I don’t have two instances of the same VM on the same network segment this is easier and avoids reconfiguring the network every time someone wants a copy of my VM.  If it is available I would suggest using the 10.0.3.* network as 10.0.2.* is the default NAT network.  You can check availability by pinging 10.0.3.1 and 10.0.3.2 from your host machine.  If it times out then you are probably safe to use that. Creating the New VMs Now that I had collected the data that I needed I went ahead and created the new VMs. When asked for a “Boot Hard Disk” I used the “Choose a virtual hard disk file…” link to find the snapshot I had previously selected and set that to be the existing hard disk.  I chose the previously existing SOA 11.1.1.5 install for both the new DB and FMW machines because that snapshot had the database with the RCU completed that I wanted for my DB machine and it had the SOA software installed which I wanted for my FMW machine. After the initial creation of the virtual machine go into the network setting section and enable a second adapter which will be bridged.  Make a note of the MAC addresses (the last four digits should be sufficient) of the two adapters so that you can later set the bridged adapter to use fixed IP and the NAT adapter to use DHCP. We are now ready to start the VMs and reconfigure Linux. Reconfiguring Linux Because I now have two new machines I need to change their network configuration.  In particular I need to change the hostname, update the hosts file and change the network settings. Changing the Hostname I renamed both hosts by running the hostname command as root: hostname vboxfmw.oracle.com I also edited the /etc/sysconfig file and set the correct hostname in there. HOSTNAME=vboxfmw.oracle.com Changing the Network Settings I needed to change the network configuration to give the bridged network a fixed IP address.  I first explicitly set the MAC addresses of the two adapters, because the order of the virtual adapters in the VirtualBox Manager is not necessarily the same as the order of the adapters in the guest OS.  So I went in to the System->Preferences->Network Connections screen and explicitly set the “Device MAC address” for the two adapters. Having correctly mapped the Linux adapters to the VirtualBox adapters I then set the Bridged adapter to use fixed IP addressing rather than DHCP.  There is no need for additional routing or default gateways because we expect the two machine to be on the same LAN segment. Updating the Hosts File Having renamed the machines and reconfigured the network I then updated the /etc/hosts file to refer to the new machine name add a new line to the hosts file to provide an additional IP address for my server (the new fixed IP address) add a new line for the fixed IP address of the other virtual machine 10.0.3.101      vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.2.15       vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.3.102      vboxfmw.oracle.com      vboxfmw # Added by NetworkManager 127.0.0.1       localhost.localdomain   localhost ::1     vboxdb.oracle.com       vboxdb  localhost6.localdomain6 localhost6 To make sure everything takes effect I restarted the server. Reconfiguring the Database on the DB Machine Because we changed the hostname the listener and the EM console no longer start so I need to modify the listener.ora to use the new hostname and I also need to rebuild the EM configuration because it also relies on the hostname. I edited the $ORACLE_HOME/network/admin/listener.ora and changed the listening address to the new hostname:       (ADDRESS = (PROTOCOL = TCP)(HOST = vboxdb.oracle.com)(PORT = 1521)) After changing the listener.ora I was able to start the listener using: lsnrctl start I also had to reconfigure the EM database control.  I first deconfigured it using the command: emca -deconfig dbcontrol db -repos drop This drops the repository and removes any existing registered dbcontrols. I then re-configured it using the following command: emca -config dbcontrol db -repos create This creates the EM repository and then configures and starts dbcontrol. Now my database machine is ready so I can close it down and take a snapshot. Disabling the Database on the FMW Machine I set up the database to start automatically by creating a service called “dbora”.  On the FMW machine I do not need the database running so I can prevent it auto-starting by running the following command: chkconfig –del dbora Note that because I am using a snapshot it is not a waste of disk space to have the DB installed but not used.  As long as I don’t run it, it won’t cost me anything. I can now close the FMW machine down and take a snapshot. Creating a New Domain The FMW machine is now ready to create a new domain.  When creating the domain I can point it at the second machine which is running the database.  I can potentially run these machines on two separate physical machines as long as I have the original virtual machine available to both of the physical machines. Gotchas in Snapshotting VirtualBox does not support the concept of linked machines in a network like some virtualization technologies so when creating a snapshot it is a good idea to shut both VMs down and then take a snapshot on both of them.  This is because we want to keep the database in sync with the middleware.  One way to make sure that this happens would be to place all the domain configuration files on the database server via an NFS share, this would mean that all we would need to snapshot would be the database machine because that would hold all the state and configuration. The Sky’s the Limit We have covered a simple case of having just two machines.  I have a more complicated configuration in which two machine run a RAC database off the same base OS image, and two more machines run a SOA cluster based on the same OS image.  Just remember what machine holds state and what are the consequences of taking a snapshot.

• Set up a GUI managed stateful filtering firewall?

  - by Azendale

  What ways are there of setting up a stateful filtering* firewall whose rules can be managed by a GUI? Can GUFW do it? FireStarter? (or should that be avoided because it is supposedly no longer updated?) *By filtering, I'm mean the traffic I am setting rules up for is not destined for this computer. It is either from or to other computers on my LAN. Say, for (a simplified, hypothetical) example: I have an ethernet connection at my dorm that I have plugged into eth0. It gets an address of 192.168.1.185 and I also have 192.168.185.0/24 routed to me, so I don't have to do any NAT. I have a hub attached to my second ethernet port (eth1) with a few Windows computers and I give addresses out of my 192.168.185.0/24 block with DHCP. How can I use my Ubuntu box to block incoming connections from eth0 that are being routed to my Windows computers and let through just a few specific ports (so fellow students can't see what files my Windows boxes are sharing via SMB)?

• [MINI HOW-TO] Remove a Network Computer from Windows Home Server

  - by Mysticgeek

  One of the cool features of Windows Home Server is the ability to backup and monitor the computers on your network. If you no longer need a machine on to be monitored or backed up, here we show you how to remove it. Remove Computer from WHS The process if straight-forward and basic –Open Windows Home Server Console and click on Computers & Backup. Right-click on the computer that you no longer need and click Remove. You’ll be prompted to verify that you want to remove the machine and delete all of its backup data. Check the box I am sure I want to remove this computer then click the Remove button. That’s all there is to it! The computer and all of its backup data is removed. Remember that if you remove a computer, all of its backup data will be deleted as well. If you no longer have the computer, you probably don’t need the backed up data anyway, but you’ll want to be sure you no longer need it before removing it.

This is the step I'm having trouble at (I'm using eth1): Edit /etc/network/interfaces, and make it look like this: auto lo iface lo inet loopback auto xenbr0 iface xenbr0 inet dhcp bridge_ports eth0 auto eth0 iface eth0 inet manual I do this, and here is my output from ifconfig: eth1 Link encap:Ethernet HWaddr 00:17:a4:f8:79:20 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:478264 errors:0 dropped:0 overruns:0 frame:0 TX packets:2895 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:46470058 (46.4 MB) TX bytes:214620 (214.6 KB) Interrupt:17 Memory:fa000000-fa012800 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) xenbr0 Link encap:Ethernet HWaddr 00:17:a4:f8:79:20 inet addr:192.168.1.122 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::217:a4ff:fef8:7920/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:471842 errors:0 dropped:0 overruns:0 frame:0 TX packets:2795 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:37005780 (37.0 MB) TX bytes:182010 (182.0 KB) So how do I give this system a static IP address? Sorry, I'm not that familiar with networking on Ubuntu.

• Wired Network not working on Ubuntu 11.10 + Strange Behavior with Manual Conf

  - by Mauricio Cruz

  I'm new to Ubuntu - to be honest this is my very first day trying it... and I've already spent hours trying to make my wired connection work. I've been using this wired network with Windows and OSX, and in both systems I also had some trouble trying to connect in the past (and the troubleshooters did their magic and helped me get connected). Today, this is what I got: I'm running Ubuntu 11.10; ifconfig: eth0 Link encap:Ethernet HWaddr 78:2b:cb:c3:bf:8f UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:1 errors:0 dropped:0 overruns:0 frame:0 TX packets:343 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:70 (70.0 B) TX bytes:63273 (63.2 KB) Interrupt:20 Memory:e2e00000-e2e20000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1859 errors:0 dropped:0 overruns:0 frame:0 TX packets:1859 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:149368 (149.3 KB) TX bytes:149368 (149.3 KB) wlan0 Link encap:Ethernet HWaddr 10:0b:a9:82:55:c0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:15484 errors:0 dropped:0 overruns:0 frame:0 TX packets:16871 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:12048377 (12.0 MB) TX bytes:2677679 (2.6 MB) I also have some information from Windows ipconfig /all that I ran at my friend's machine Ipv6 Address: <address> preferential Ipv4 Address: 172.26.65.23 <preferential> Netmask: 255.255.254.0 Default Gateway: 172.26.64.1 DHCP Server : <address> DNS Servers : <address> DNS Suffix : <suffix> The weird thing is that I've tried to configure everything manually, using "Network Connections". When I add everything inside IPv4 Settings, the connection is finally successful, but only for 4~5 seconds before getting disconnected again... Update:I just changed the Connection Method to "Local-Link Only", and the same described above happens: At first, it says "Connection Stablished", but after a few seconds, the wired network gets disconnected. I hope someone can help me get connected! Thanks!

• What are my options for sharing music between Windows & Ubuntu on the same network?

  - by jgbelacqua

  We have a few Windows(XP & 7) and Ubuntu machines in the house sharing a wireless connection, and want to share music between them. If possible, I would like to be able to serve music from both Windows and Ubuntu (but it doesn't have to be the same time). I don't know much about sharing folders or streaming, but I'm guessing both would be options (that is, using a local client to access a shared song or a local client to access a shared stream). I want to be able to share the music between the systems as simply as possible. Bonus points (but not requirements) for cross-platform -- same application on both Windows and Ubuntu? available on startup (via daemon or autostart or whatnot) open source More info: All systems have dynamic addresses (DHCP) supplied from the ISP-supplied wireless router. There are several Gigabytes of music on one Windows XP box and one Ubuntu 10.10 The music is not well-sorted (I'm thinking this might have an impact on UI usability). Only has to be available internally (private address space behind the wireless router) bandwidth is not a problem We don't have (legitimate) admin access to the wireless router
