  • Failed to open the Parallels networking module

    - by user49204
    I'm running Parallels Desktop 7 on OSX Lion and encounter the issue in the subject on every time I'm trying to launch Parallels VM. The error message contains a hint to restore to network configuration default which does not help. As been advised by some forums to ran the following script: sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_hypervisor.kext" sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_hid_hook.kext" sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_usb_connect.kext" sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_netbridge.kext" sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_vnic.kext" The output of: sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_netbridge.kext" is: Diagnostics for /Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_netbridge.kext: Warnings: The booter does not recognize symbolic links; confirm these files/directories aren't needed for startup: /Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_netbridge.kext/Contents/CodeDirectory /Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_netbridge.kext/Contents/CodeRequirements /Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_netbridge.kext/Contents/CodeResources /Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_netbridge.kext/Contents/CodeSignature Dependency Resolution Failures: No kexts found for these libraries: com.parallels.kext.prl_hypervisor I've noticed that prl_netbridge is not being loaded (when I'm trying to unload it, I'm notified it is not loaded). Am I doing something wrong? What can be the reason for such behaviour?

  • iPhone Remote with iTunes Library via VPN

    - by sudo work
    Alright, so I'm currently behind a network router (not under my control). The router performs NAT and somehow prevents a computer from scanning other nodes. At least, you're unable, in this instance, to locate an iTunes library. You can, however, communicate with a node's open ports if the local IP address is known, as well as the port. I haven't actually tried port scanning a specific IP using nmap or another tool yet. So I've tried one solution to remove the contribution of the router entirely (to verify that it works without the influence of the routers). I set up an access point using my iPhone and tethered my computer (with the library) to it. From here, I was able to pair my library and the iPhone Remote application. Control of the library was normal as well. This solution is not ideal, however, because I am actively using bandwidth with my computer and cannot afford to be tethered to my 3G connection. A viable solution for me is to use a common VPN connection, which I have set up on a Ubuntu (Intrepid) server that is remote. Both my computer and iPhone are able to access the VPN via PPTP. The server is setup with PPTPD as the VPN-server; I'm using IPTables to perform IP masquerading and forwarding traffic. I however, still cannot connect the library to the phone. I can however, see both devices on the VPN subnet (192.168.0.0/24). SSH'ing and such works fine. What settings on the VPN server must I change to get this to work? Also, how can I assign static IP addresses to various PPTP clients based on MAC addresses?

  • Unable to receive any emails using postfix, dovecot, mysql, and virtual domain/mailboxes

    - by stkdev248
    I have been working on configuring my mail server for the last couple of weeks using postfix, dovecot, and mysql. I have one virtual domain and a few virtual mailboxes. Using squirrelmail I have been able to log into my accounts and send emails out (e.g. I can send to googlemail just fine), however I am not able to receive any emails--not from the outside world nor from within my own network. I am able to telnet in using localhost, my private ip, and my public ip on port 25 without any problems (I've tried it from the server itself and from another computer on my network). This is what I get in my logs when I send an email from my googlemail account to my mail server: mail.log Apr 14 07:36:06 server1 postfix/qmgr[1721]: BE01B520538: from=, size=733, nrcpt=1 (queue active) Apr 14 07:36:06 server1 postfix/pipe[3371]: 78BC0520510: to=, relay=dovecot, delay=45421, delays=45421/0/0/0.13, dsn=4.3.0, status=deferred (temporary failure.

  • DD-WRT PPTP VPN problem

    - by Tobias Tromm
    I try to configure a DD-WRT as a PPTP client. The VPN Server is Windows Server 2003. This is my scenario: The Windows 2003 Server has set to give to the VPN Client the 10.0.0.81 fixed IP and to add a network route to the remote home. At the remote home I have changed the PPTP Options at DD-WRT to make the connection. The VPN connection is successfully established. ...and Windows successfully add the route to the remote home 192.168.2.X. From the remote home I can successfully access any computer from the VPN server side. The problem is when I try to access the remote home from the Server side. From Server side I only can access\ping DD-WRT ( by VPN Client IP - 10.0.0.81). What's wrong? How I need to do to be a site-to-site VPN? This is what happen when I try to tracert the remote home from local home.

  • Oracle with Kerberos authentication and Windows 2003 Server as KDC

    - by Supaplex
    I am running Oracle 10.2 on a Windows 2003 Server SP2 which is also the domain controller on the network. I wish to switch authentication method from NTS to Kerberos. I have spent a lot of time trying to configure Oracle with Kerberos authentication from the Oracle Advanced Security option from the Net Manager utility. I have disabled NTS so Kerberos is promoted as the preferred authentication method. But as soon as the configuration is saved from Net Manager and I restart the Oracle server service, Oracle will not start. I don't know what Oracle is complaining about, because I don't know where to look for the Oracle error log. My first question is: how can I figure out what's bugging Oracle? My second question: is there a good tutorial for setting up Oracle on a Windows 2003 with Kerberos Authentication, where the Windows 2003 Server is the KDC? Maybe there is a book I can get? I have read Oracles own guide, but it is mostly for Linux/Unix. Thanks a lot!

  • Advice on networking career

    - by fmysky
    Hello! I need some insights on a networking career. I have a valid CCNA and few months of experience as a Jr. network analyst. My focus is a type of job where I can administer networking/storage hardware and possibly managing servers/workstations too. I am new to this job area, specifically new to city like LA. I am currently unemployed and so, my question is: should I continue with my cisco certifications(routing/wireless) or other comptia certs or both to get a reliable job? I am really interested in CCNA wireless but watching craigslist(LA) and other job sites, it seems people need more cisco voice people. While, some others also ask for Net+ certs. I have scarce financial sources so, its better to make some good decisions. I have not been applying yet due to some personal problems but I will soon. Thank you! P.S. I don't know if I can ask questions like this here. Sorry about that.

  • How can I add a wireless router to a wired router?

    - by Tester101
    The Setup: wired D-link (EBR-2310) router connected to my cable modem. Wireless NetGear N300 (WNR2000v3) router connected to a LAN port on the wired router. What I'm trying to do: I'm trying to setup the wireless router to be a separate network, that only accesses the internet through the wired router. What I've done so far. I setup the wireless router's WAN port to get an address from ISP (which should be coming from my wired router running DHCP), and the LAN as a subnet (192.168.1). Wired router's LAN is 192.168.0. The problem: I'm not able to connect to the internet from the wireless router. At one point my wired router showed that it was handing out an IP to the wireless router, but that is not happening anymore. The question: Is what I'm trying to do possible? Am I not thinking about this properly? Do I need to buy a better wired router, with 2 WAN ports? How can I configure these routers to work together?

    Has anyone been able to use jumbo frame support on their 2010 Macbook Pros? This is kind of negative news here, but I am seeing many reports that this is not available anymore due to Apple's choice of network card in the new machines. I cannot set my MTU speed over 1500 on my new 2010 MBP i7, but my old early 2008 MBP (Core2) has the 9000 MTU setting for use. Everything I have is setup to use jumbo frames and I thought apple kept that feature in their "pro" lineup. It sounds like the Mac Pro still has it. Did they decide to use a chipset that doesn't support it? I am trying to pinpoint some solid chipset numbers and the feature support. Maybe they just need to update the drivers? Is there some more official information about this feature? This might seem minor, but this is really frustrating if apple removed this feature from their pro laptop line. From what I have read so far, it sounds like I am not alone in my frustrations with this. http://discussions.info.apple.com/message.jspa?messageID=12258067 http://discussions.apple.com/thread.jspa?messageID=12130158 Anyone have any experience or further knowledge about this issue ... beyond typing my question into google and giving the top 5 results as answers? :)

  • HP Procurve Issue Passing Multiple VLANs over a link

    - by MichaelRwat
    Just to start off with I am a Cisco guy that got placed into an HP project. Basic topology overview from outside in: ASA 5505 with two Ethernet connections to a 2910-24 port switch. This switch is then (Cisco Trunking) to a 2626 switch passing vlan (1 untagged and 100 tagged)between them. I created SVI's on each of the switches for both VLAN's for testing purposes. I can not get vlan 100 to pass across this link. I also have trunks configured to AP's off of the switch and can not ping the vlan 100 BVI on the AP's but can reach the vlan 1 BVI. Port 25 on Access layer (2626) connects (trunks) with port A1 of 2610. STP is not running at all on any switch (this is not my network I can't change this nor did I design this) Distribution Sw: MP1-0# show run ip default-gateway 10.100.100.100 vlan 1 name "DATA" untagged 1-22,24-A1,B1 ip address 10.100.100.6 255.255.255.0 no untagged 23 exit vlan 100 name "GUEST" untagged 23 tagged 24-A1 ip address 10.100.102.6 255.255.255.0 exit Access Sw: ip default-gateway 10.100.100.100 vlan 1 name "DEFAULT_VLAN" untagged 1-26 ip address 10.100.100.5 255.255.255.0 exit vlan 100 name "GUEST" ip address 10.100.102.5 255.255.255.0 tagged 15,25 exitt From the ASA I can ping the vlan 100 address of the 2610 but not the 2626 (10.100.102.6)[Not passing the "trunk"] If I plug into an access port vlan 100 of the 2626 I can ping the SVI for vlan 100 as intended. I can not ping across the "trunk" over vlan 100 but I can across vlan 1. There may be something obvious I'm missing but please review my configuration and thank you for the assistance.

  • How to make DD-WRT router's (configured like a repeater) devices be accessible on LAN? (i.e. integrate DHCP for both routers)

    - by Annonomus Penguin
    I have a D-Link DIR-600-A1 router running DD-WRT (using the 601's firmware: except for the model number, they are near identical). It has an Atheros chip, so there is no "repeater" option. You can bypass this by setting the main radio as a client to the main router, and adding a virtual radio configured as an AP. You can then set up the credentials for connecting to the main router and allowing devices to connect to the repeater/router. I have a few devices on my network: Ethernet computers Server with Samba running WiFi devices connected to the main router I then wanted to add a repeater. I have a couple of other things on the repeater: WiFi Computer Other WiFi devices. Anyway, I wanted to connect my WiFi computer to the share on my server via Samba. However, for some reason, my router treats the main router as WAN, not another device. I've tried disabling the SPI firewall: However, that doesn't work. I've tried pinging my WiFi computer from my server. However, I can ping my server from my WiFi computer. AFAIK, they are on the same subset, just using different IPs: the main one uses 192.168.0.x and the repeater uses 192.168.1.x (starting at 100 for some reason). It seems as I need to configure my router(s) to work together for DHCP. I noticed there was a "DHCP forwarder" option, but I have no idea what that would do. A quick note: for some reason (that's beyond me) my ISP disabled the capability to bridge a WiFi to ethernet connection with the router they provide (something about PPPoE or similar...). The service rep I talked to when I was having issues after I changed ISPs said that, but they couldn't explain exactly what they were "blocking." How can I get DD-WRT to not treat the client connection as WAN and the router to recognize the devices connected to the repeater?

  • Wifi Drops Connections with WPA2-PSK

    - by graf_ignotiev
    I run a small computer lab made up of 10 computers of identical hardware and software (Dell Latitudes with Windows 7 x64 Enterprise) and I use a ZyWALL 2WG as a router/firewall. Nine of the computers connect to the router over wifi using WPA2-PSK encryption while the last one is connected by ethernet cable. I'm having a problem where any computer connected to the wi-fi occasionally drops off the network (it cannot be pinged and the client cannot ping the gateway). It only happens on the wifi side and only when the encryption is WPA2-PSK or WPA-PSK. I tried using another router with a different make and model and had no problems. Thinking it could be a software error, I reset the router to factory defaults and installed the newest firmware (V4.04(AQI.8) | 04/09/2010), but still have the problem. The 802.1X log gives the following error User logout because of user disassociation. with this note WPA2-PSK:00242c582ece:logout where 00242c582ece is the mac address of the device. At this point I'm out of things to try and leads to follow. It looks like this user had the same or similar problem, but none of those proposed solutions work for me.

  • VPN Error 619: Behind Cisco Router WRT310N

    - by ty91011
    I've researched a lot on all the forums and this error is too generic for any of the proposed solutions to work. I'll try to give as much detail and tried solutions. I'm running a CentOS PPTP server behind a Cisco WRT310N Router. Multiple clients from outside with different OS have failed with the same error 619, along with turning off windows firewall and disabling antivirus. I believe this is a router and IP routing issue, and not a client issue. When I connect from a client on the same router as the VPN server, it works when I use the 192. network address- but doesn't work with the public IP address. I've tried telnet to port 1723 from an outside server and I get in. I've opened up the VPN port (1723) on the router, VPN udp port (500), and the GRE port (47) to route to the VPN server's ip. Also, the server's router is behind a DSL modem. I had a glimmer of hope when this site: http://www.chicagotech.net/casestudy/vpnerror619.htm suggested that the PPoE authentication should reside on the router and not the modem. But I still came up empty. So does anybody know what the problem is?

  • Gluster bricks are offline and errors in logs

    - by Roman Newaza
    I have substituted all the IP addresses with hostnames and renamed configs (IP to hostname) in /var/lib/glusterd by my shell script. After that I restarted Gluster Daemon and the volume. Then I checked if all the peers are connected: root@GlusterNode1a:~# gluster peer status Number of Peers: 3 Hostname: gluster-1b Uuid: 47f469e2-907a-4518-b6a4-f44878761fd2 State: Peer in Cluster (Connected) Hostname: gluster-2b Uuid: dc3a3ff7-9e30-44ac-9d15-00f9dab4d8b9 State: Peer in Cluster (Connected) Hostname: gluster-2a Uuid: 72405811-15a0-456b-86bb-1589058ff89b State: Peer in Cluster (Connected) I could see mounted volumes size change on all the nodes when I execute df command, so new data is coming.

  • Adding Static IP's to the NIC

    - by Brett Powell
    We are currently working on migrating a lot of new machines to our network, and my job this morning was to setup all of the IP Addresses. I worked on this all morning, and when I got back tonight I was informed that they had all been setup incorrectly, and had to be removed and re-added. I am quite confused as I have been setting up IP's on machines for a long time and I am curious as to what the issue is. Just taking into account this example... 72.26.196.160/29 255.255.255.248 A /29 block is 5 usable IP's. With the script I wrote and used, the IP Addresses .162 - .166 were added to the NIC. I can't remember now what the name for .161 was, but isn't it the broadcast address or something which isn't assigned to the NIC when adding additional IP Blocks? I am curious as to where my logic is failing me. Not to mention even if .161 was to be added, there is no reason why all of the IPs would have to be removed, as .161 could just be added in addition to these.

  • sql developer cannot establish connection to oracle db with listener running

    - by lostinthebits
    I am working from home and connected to my work's vpn. I have tried to connect to the work db with sql developer (the latest version and the previous version) on the following environments: mac os x 10.8.5 (with sql developer launched and installed directly on the iMac. sql developer launched and installed directly on a vm on same computer (guest Ubuntu 12.04 LTS) sql developer launched and installed directly on a vm on same computer (guest Windows 7.0 Professional) I get Status Failure Test Failed : IO Error - The Network Adapter could not establish the connection. I have read dba forums and googled and the most common suggestion is that the oracle listener is not up and running. I can conclusively say this is not the case because I have the option of using remote desktop and accessing the oracle db in question on my work computer. If the listener was down, according to my DBA, no one would be able to connect. My sysadmin and dba are stumped so I assume it is something unique to my home system. The reason I do not want to continue with the remote desktop workaround is because remote desktop has an annoying (infuriating often) lag.

  • run as dialog always pops up

    - by user12006
    I recently got some malware on a machine that I don't use for much (partly intentional). I've cleaned it, but now everytime I open any .exe the 'Run As' dialog pops up asking me which user I want to use to run the program. What causes this, and what's the fix for it? edit My process to remove the malware was as such: Disconnected from the network Deleted DisableTaskMgr reg key Inspected with Process Explorer and Task Manager and noticed that all applications were being run within another executable located in Documents and Settings...\Temp\Some.exe The system tray application was also in Documents and Settings...\Temp\SomeOther.exe I suspected that a service was in place as the system tray application would restart if it was killed, but couldn't find any service that I didn't recognize. Removed permissions from Some.exe and SomeOther.exe (on those files only) Restarted and deleted Some.exe and SomeOther.exe Deleted startup entries that were created Ran AVG Free and Windows Defender to remove anything else (they would be killed immediately before the two .exe's were removed) Cleaned registry via CCleaner note that system restores would finish saying something to the effect of 'couldn't restore system: there were no changes made'. I attempted to restore to a week ago, and I only got the malware yesterday.

  • How to configure a Router (TL-WR1043ND) to work in WDS mode?

    - by LanceBaynes
    I have a WRT160NL router (192.168.1.0/24 - OpenWrt 10.04) as AP. It's: - WAN port: connected to the ISP - WLAN: working as an AP, using 64 bit WEP/SSID: "MYWORKINGSSID", channel 5, using password: "MYPASSWORDHERE" - It's IP Address is: 192.168.1.1 Ok! It's working great! But: I have a TL-WR1043ND router that I want to configure as a "WDS". (My purpose is to extend the wireless range of the original WRT160NL.) Here is how I configure the TL-WR1043ND: 1) I enable WDS bridging. 2) In the "Survey" I select my already working network. 3) I set up the encryption (exact same like the already working one) 4) I choose channel 5 5) I type the SSID 6) I disable the DHCP server on it. After I reboot the router and connect to this router (TL-WR1043ND) over wireless I'm trying to ping google.com. From the ping I see that I can reach this router, that's ok, but it seems like that this router can't connect to the original one, the WRT160NL (so I don't get ping reply from Google). The encryption settings/password is good I checked it many-many-many times. what could be the problem? I'm thinking it could be a routing problem, but what should I add to the "Static Routing" menu? I tried to change the IP address of the TL-WR1043ND to: 192.168.1.2 So if this a routing issue then I should add a static routing rule that says: If destination: any then forward the packet to 192.168.1.1 p.s.: I updated the Firmware to the latest version. It's still the same. p.s.2: The HW version of the TL-WR1043ND is 1.8 p.s.3: Could that be the problem that I use different routers? (If I would buy.. another TL-WR1043ND and use it instead of the WRT160NL, and with normal Firmware, not OpenWrt, then it would work?? The "WDS" is different on different routers?) p.s.4: I will try to check the router logs@night - and paste it here! :\

  • Can't connect to a Hyper-V VM from anywhere but the host OS

    - by Elbelcho
    I have an unusual situation on hand where I'm able to connect to a Hyper-V guest VM from the HOST, but not from anywhere but the host. The VM is running WIn2k8R2 and has IIS installed and Remote Desktop enabled. If I browse to the IP from the host OS, the IIS7 page displays. I can also RDP into the guest OS from the host as well as ping. From OFF the host, RDP, web and ping all fail. If I completely shut off the guest VM's firewall, ping will then start to respond, but all RDP and port 80 still don't. The physical host machine has 2 nics installed, but only one is plugged in. The one plugged in has a static IP. I have one Hyper-V virtual network and it's set to external. The guest VM has one NIC with a different static IP than the host, but both are on the same subnet. The host machine is joined to the domain, the guest VM is not. Any sugestions? Thanks so much for any help you may be able to provide!

  • Cisco "copy startup-config tftp" results in a 0 byte file on the server?

    I'm pulling my hair out figuring this out. My startup-config is good, I can view it with a show command. I'm trying to copy it to a tftp server: asa5505# copy startup-config tftp Address or name of remote host []? ipaddress Destination filename [startup-config]? t !! %Error writing tftp://ipaddress/t (Timed out attempting to connect) On my TFTP server (SolarWinds), I get the following: binary, PUT.

Interrupted by client, cause: The process cannot access the file 'C:\TFTP-Root\t' because it is being used by another process I've used tftpd32 with same results. I've tried different servers, even one on the same network as the asa ... same results. It'll create a 0 byte file and never do the dump. What's going on? Everything is working normally except for this.

  • Why is my cat5e cable not okay?

    - by torbengb
    My LAN cable seems to work (indicator LED lights up) but the computer can't find a connection. What's wrong? Setup: I had to run a network cable from a router in one room to a computer to another room, through a hole in the wall that was too small to pass the RJ-45 plug through. The plug was cut off and the cable passed through the wall. Then a new plug was crimped on using this detailed explanation. The connection didn't work because the (factory-made!) plug in the other end used a non-standard wire order. I crimped a new plug on again, using the exact same order of the factory-made plug. The LED indicator lights up on both ends, but the computer cannot find a connection. What can be wrong? How can I find out? I don't have a cable tester. By visually inspecting my new plug, I think it's good; the wire order matches the other end, and all wires are all the way inside the plug and reach the connector piece. I've used the cable before (with both factory-made ends) so i don't think that the cable itself has a defect.

  • How does enterprise failover, such as with google.com, actually work?

    - by Alex Regan
    We have a few fedora systems that are configured for web, FTP, and email services. We'd like to mirror these services, so that we can provide near 100% reliability for our users. I'm a fairly experienced Linux administrator, but don't have much experience with redundant systems. What is the best way to do this? How does google and amazon do it? Google.com resolves to multiple IP addresses, but if my local desktop caches one of the IPs that are unreachable, I'm going to get a failed connection message. How do they prevent that from happening? If one of their servers goes down, how is it automatically redirected to another system, without the end-user ever knowing it? I understand there are failover devices, but they're only for failing over the system itself, not a complete network. Let's say we have the worst-case scenario, such as my primary system becomes inaccessible. What are the fundamental components that are used on Linux systems to provide this capability? I'm looking for concepts, or approaches, not answers like "check out openstack". What are the actual pieces that make up the solution? What has to be done to implement this capability? Hopefully my question is clear. I'd like to know what the pieces are that make up a failover system and what approach is taken by successful organizations that implement it. Thanks again, Alex

  • What's the best way to telnet from a remote Windows PC without using RDP?

    - by Rob D.
    Three Networks: 10.1.1.0 - Mine 172.1.1.0 - My Branch Office 172.2.2.0 - My Branch Office's VOIP VLAN. My PC is on 10.1.1.0. I need to telnet into a Cisco router on 172.2.2.0. The 10.1.1.0 network has no routes to 172.2.2.0, but a VPN connects 10.1.1.0 to 172.1.1.0. Traffic on 172.1.1.0 can route to 172.2.2.0. All PCs on 172.1.1.0 are running Windows XP. Without disrupting anyone using those PCs, I want to open a telnet session from one of those PCs to the router on 172.2.2.0. I've tried the following: psexec.exe \\branchpc telnet 172.2.2.1 psexec.exe \\branchpc cmd.exe telnet 172.2.2.1 psexec.exe \\branchpc -c plink -telnet 172.2.2.1 Methods 1 and 2 both failed because telnet.exe is not usable over psexec. Method 3 actually succeeded in creating the connection, but I cannot login because the session registers my carriage return twice. My password is always blank because at the "Username:" prompt I'm effectively typing: Routeruser[ENTER][ENTER] It's probably time to deploy WinRM... Does anyone know of any other alternatives? Does anyone know how I can fix plink.exe so it only receives one carriage return when I use it over psexec?

  • DIY NAS - links for Instructions

    - by Kaushik Gopal
    Good folk of SU, I'm planning to build a NAS (Network Access Storage). I'm planning to do it cheap (:read Old PC Config + Open source software). I was looking for good DIY links . Before you shoot this down as a Repost, I'm only looking for good links containing detailed instructions for setting up a NAS. I did a fair bit of searching and found these links (so please suggest others. While these links are great they delve more on the hardware side, i'm looking for more instructions in the software side). For the sake of the interwebs: Ubuntu: http://snarfquest.com/wiki/index.php/Setting_up_a_Home_NAS http://www.smallnetbuilder.com/content/view/27962/77/ http://jonpeck.blogspot.com/2006/11/how-to-configure-80-fileserver-in-45.html FreeNAS http://www.smallbusinesscomputing.com/webmaster/article.php/3719706 http://www.codeproject.com/KB/system/homemade_nas.aspxhttp://www.codeproject.com/KB/system/homemade_nas.aspx There was one at rubbervir.us that everyone points to, but apparently the site has gone down. A couple of other queries: Is Printer/Scanner sharing a possibility with NAS devices? Many talk of torrent support with NAS Devices, a little more light on this? Does this mean, an auto download of torrent through a feed into NAS, or just support for storing Torrent download files onto the NAS(don't see the difference between the latter and a normal file tranfer)
