  • Intranet Setup for Small business any resources?

    - by Rogue
    Want to setup an intranet for a small business setup. Current Setup 28 computers running Windows ( few older pc's run Windows Xp but most run Windows 7) Spare Dell Pentium 3 which can run as a server. 6 switches spare NIC's and lots of lan cable available for networking. 3 Independent Internet connections Currently we have 3 independent networks which share internet connections, each network uses a different internet connection. Current network is setup solely to share the internet connection. What I need to achieve in this intranet Setup one common network. Instant file transfer via local network (maybe setup a file server?) Local text and voice messenger software Bridge the 3 internet connections and route all the internet connections from the main server Ability to allow or deny internet access to any computer on the network. Remote access from the main server to the client pc's on the network to debug software issues What operating system should I use on the main server? Do I need a hardware firewall? Any setup guides / resources or how-to's on how I can achieve the above requirements.

  • Bypassing SQUID on freebsd with PF

    - by epema
    I have PF+SQUID31 on FREEBSD-9.0, and I want to have some hosts(aka goodguys) to bypass the proxy, so that torrents are not logged. Also, I am not sure about transparent. It means that I dont have to configure proxy settings on the client side right? I have tried doing a redirect no rdr on $int_if inet proto {tcp,udp} from 192.168.1.233/32 to any However, no luck :( Here is a quick look of my conf files: SQUID /usr/local/etc/squid/squid.conf http_port 192.168.1.1:8080 transparent RC /etc/rc.conf: gateway_enable="YES" pf_enable="YES" pf_rules="/usr/local/etc/pf.conf" pflog_enable="YES" squid_enable="YES" I have squid31 installed from ports with SQUID_PF "Enable transparent proxying with PF" on PF /usr/loca/etc/pf.conf: int_if="re0" ext_if="bge0" localnet="{ 192.168.1.0/24 }" table <goodguys> const { "192.168.1.219", "192.168.1.233" } set block-policy drop set skip on lo0 scrub in all fragment reassemble scrub out all random-id max-mss 1440 block in on $ext_if pass out on $ext_if keep state block in on $int_if pass in on $int_if inet proto tcp from $int_if:network to $int_if port 8080 keep state pass in on $int_if inet proto udp from $int_if:network to $int_if port 21 keep state pass in on $int_if inet proto udp from $int_if:network to $int_if port 22 keep state pass in on $int_if inet proto udp from $int_if:network to $int_if port 53 keep state pass in on $int_if inet proto tcp from $int_if:network to any port { smtp, pop3 } keep state pass in on $int_if inet proto icmp from $int_if:network to $int_if keep state pass out on $int_if keep state What lines should I add in conf files? I am assuming that the problem is on the firewall(pf).

  • pfsense, active directory, local domain

    - by Dalton Conley
    First things first, I have no idea what I'm doing. Certainly not afraid to admit that.. but here is my network setup. I have 2 servers, one of them in a domain controller. Both are running windows server 2008. They have replicated directories. Each server is at a different location and has its own firewall for the network at that location. Both firewalls are using pfsense. Recently a firewall went down and my coworker reinstalled pfsense, and everything seems setup correctly. Again, I have no idea what I'm doing so I'm not sure. I have records from when the previous IT person had setup this network and the firewall settings are the same but those records could have been extremely old. Now, I have a domain name for my network.. we'll call it "mydomain.net". I use to be able to access this domain name and it would bring up the servers replicated drives(i.e. \\mydomain.net). Now I cannot. I can however access the servers individual host names on my network(i.e. \\server1 , \\server2). We didn't change anything on the server which is what makes me think its something to do with the firewall. I know this is probably a very general question and I don't have a lot of detail to add but could anyone give me some insight on to what could be causing this, or some debugging techniques I can apply to this? I'm a programmer, not a network administrator.

  • Using PowerShell, in Active Direcotry, how would I change all the DNS A records that have a given IP to a new IP?

    - by djsumdog
    We've been moving data centers and I have a lot of old records that were not correctly but in DNS as CNAME records, but A records that have a direct IP (e.g. 192.168.100.n) and they're all moving to a new subnet (10.19.100.n). I just need to write a powershell script to change all those records. I found this site: http://www.indented.co.uk/index.php/2008/12/30/administering-microsoft-dns-in-powershell/ and from it I made this simple script: $dnsServer = "meldc2" $scope = New-Object Management.ManagementScope("\\$dnsServer\root\MicrosoftDNS") $path = New-Object Management.ManagementPath("MicrosoftDNS_Zone") $options = New-Object Management.ObjectGetOptions($Null,[System.TimeSpan]::MaxValue, $True) $ZoneClass= New-Object Management.ManagementClass($scope,$path,$options) $Zones = Get-WMIObject -Computer $dnsServer -Namespace "root\MicrosoftDNS" -Class "MicrosoftDNS_Zone" $Zones | Get-Member foreach($Z in $Zones) { $Z | Select-Object Name,DsIntegrated,ZoneType,Reverse,Data } but that only gets me a listing of root zones. I don't understand how to iterate over all the entries in each of the zones. Also, all the examples I've seen involve adding new zones, but there aren't any examples I can find on modifying existing A records.

  • In search of a good audio player for Ubuntu 9.10

    - by Joe Casadonte
    If this should be marked Community Wiki, please let me know. I'm switching from XP to Ubuntu, and I have been very disappointed with the selection of media players available. I'm primarily interested in an audio player, but integrated video and library management is OK, too. My criteria: Must be able to play audio CDs (I'm shocked how many apps this does away with, right away) Must be able to play MP3 & WAV; OGG, SHN, FLAC are all bonuses Repeat and Shuffle modes are a must FreeDB / GraceNote through a proxy is a must (if it can read a PAC file, that would be awesome) It needs to be really small, e.g. skinnable or an applet Ability to execute a playlist is a plus Gapless MP3 playback a plus I'm running Gnome, but I'm not totally adverse to a KDE app. Command-line only is also a viable option. Some that I've tried: RhythmBox - probably the best of the lot that I've tried; I don't like its mini mode (doesn't show the song being played) and I can't figure out how to get it to hit FreeDB/GraceNote through a proxy Songbird - can't play CDs, playlist management is atrocious Banshee Jajuk Maybe a couple of more. Thanks! UPDATE I tried out VLC, Amarok and Songbord (again). VLC I eventually got to work (I had some kind of bad configuration). It seemed way more involved than I was looking for out of a music player, and in general more geared to video than audio. I couldn't fathom its library management, which I think it has; maybe it doesn't, and that's why I couldn't figure it out. Amaork looked very promising but the library management was not to my liking, and the way it handled a playlist with both MP3 and WAV is inexplicable at best. I did like some aspects of the UI, but not enough to keep it. Songbird is very finicky, but I like the library management. Sort of. It kept telling me my Watch folder was invalid, even thought it clearly was accessible. Playlist management is bizarre, and the message that it was deleting source files whenever I deleted a playlist had me too worried to keep using it. Had it been able to play CDs, maybe I would have persevered. Audacious, while a bit odd at times, does seem to do what I want. If it had a library manager, I wouldn't have bothered trying any of the others. Thanks for the help, everyone!

  • Hyper-V: Dedicated NIC for Guests VMs

    - by TheLizardKing
    I have two NIC cards and created a private virtual network for my virtual machines and unchecked "Allow management operating system to share this network adapter" which basically turns my Guest NIC into this sorta shell of a NIC card on the host machine and the only thing checked in it's properties is "Microsoft Virtual Network Switch Protocol" which I am fine with. Everything works and everything is connected. My issue is that for some reason my guest (Ubuntu Server with legacy network drivers) is not talking properly to my DHCP server. Specifically my DHCP server reserves the guest's IP address using it's MAC address but the guest isn't picking it up. It's picking up any old IP it can get and I can't even ping the hostname from another PC on the network but it pings fine if I use the IP. I see the guest showing up in my DHCP table but I can't get the reservation to stick. Is there some reason it's only partially communicating with my DHCP server? Pinging it's hostname on itself reveals it's using 127.0.0.1 instead of it's network IP. Is this an issue with the legacy drivers used in Hyper-V?

  • Block users from Social networking websites while firewall is down

    - by SuperFurryToad
    We currently have a SonicWall firewall, which does a pretty good job a blocking Social networking websites like Facebook and Bebo. The problem we are having is that sometimes we need to temporarily disable our firewall blocklist so we can update our company's page on Facebook for example. Whenever we do this, have see an avalanche of users logging on to their Facebook pages during work time. So what we need a way to block access while the firewall is down. For the sake of argument, we have two groups of users - "management" and "standard users". "standard users" would have no access to Facebook, but "management" users would have access. Perhaps something like a host file redirect for non-management users. This could probably be enforced via group policy that would call a bat file to copy down the host file, depending if the user was management or not. I'm keen to hear any suggestions for what the best practice would be for this in a Windows/AD environment. Yes, I know what we're doing here is trying to solve a HR problem using IT. But this is the way management wants it and we have a lot of semi-autonomous branch offices that we don't have a lot of day to day contact with, so an automated way of enforcing this would be the most preferable method.

  • Linux wireless disconnect every 20 minutes

    - by james
    My laptop uses CentOS 6.3 with kernel 2.6.32-279.el6.x86_64. My wireless adaptor is Intel Corporation Centrino Wireless-N 1000. My wireless connection always get off after about 20 minutes. The network applet shows the connection is still on with good signal strength, but I just cannot load any web pages even the configuration page of the wireless router. The problem will continue until I disable and reconnect the wireless. Other devices like my cell phone uses the same wireless network without the problem. Even yesterday I'm using the same laptop with Fedora 17 without this problem. I also searched the internet and someone said running services NetworkManager and network simultaneously may be a problem. But I cannot stop any one of them because: if I stop network and start NetworkManager, the network service will start automatically; if I stop NetworkManager and run network, it says "Device does not seem to be present, delaying initialization." when trying to bringing on the wireless. What shall I do to get rid of the problem? Thank you very much!

  • Connect by Wifi to Sql Server from another computer

    - by Bronzato
    I try to connect by Wifi to Sql Server with Sql Server Management Studio from another computer but it failed. I have a computer with Windows Seven & Sql Server 2008 (lets say the server computer). Next to it, I have a fresh installed computer with Windows Seven & Sql Server Management Studio (let's say the client computer). What I do on the server computer: configure firewall by enabling port 1433 enabled network protocols (TCP/IP) inside Sql Server Configuration Manager checked "Allow remote connections to this server" on server properties in Sql Server Management. started Sql Server Browser restarted services (Sql Server Browser is stopped but I think it is not neccessary, isn't it?) Next, I successfully tested a ping on the port 1433 from my client computer with a tool named tcping (ex: tcping 192.168.1.4 1433). But I still cannot connect from my client computer to Sql Server on my other computer. Ok, something new on this problem: until now, I successfully connected to my "server computer" with Management Studio. What I do is typing the computer name in the server name field in the connection window of Management Studio. My previous (failed) attempt was to type the computer name followed by the instance of sql server (ex: COMPUTER_NAME\SQL2008). I don't know why I only have to type the computer name... Nevermind. Now my new challenge is to succeed connecting my VB6 application to this remote database located on my "computer server". I have a connection string for this but it failed to connect. Here is my connection string: "Provider=SQLOLEDB.1;Password=mypassword;User ID=sa;Initial Catalog=TPB;Data Source=THIERRY-HP\SQL2008" Any idea what's wrong? Thanks

  • how to setup a bridge with 2 NICs and few virtual machines

    - by Bond
    Here is my situation. I have a server with 2 NICs. I have installed virtual box and I have created a few Guest Operating Systems on it. I want these Virtual Machines to be using a bridge.NIC2 would be used to setup this bridge and NIC1 would be connected to corporate network.I am not clear with how should I go on doing this. /etc/network/interfaces is the file which I am trying to modify etc. My approach is following 1) Define a configuration file /etc/network/interfaces 2) Create IPTABLES as how NIC1 will forward the packets to Bridge on NIC2 Now comes the problem I do not understand what is the meaning of following lines in the configuration file auto lo iface lo inet loopback # The primary network interface auto eth2 iface eth2 inet manual auto br0 iface br0 inet static address 192.168.1.14 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.10 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 192.168.13.2 dns-search myserver.net bridge_ports eth2 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off So any pointers to what should be the entries of /etc/network/interfaces file. So that I understand which parameter is to be used when and where that would help me.

  • Wireless router setup for 1-1 NAT

    - by Carlos
    What I have: A linksys router WAG160N with firmware version 2 A "pool" of 5 external static IP's provided by my ISP 213.xx.xxx.n All the required configuration values for the static IPs such as (Subnet Mask, Gateway and static DNS 1, 2, 3) Current WAN Configuration: Encapsulation: RFC 2364 PPPoA Multiplexing: VC QoS type: UBR DSL modulation: MultiMode What's connected to the network: 1 x Server (That I want to make available to the outside) 5 x Desktops with static internal IP's, such as 192.168.0.xx 2 x Network printers, also with internal static IP's 2 x Laptops 1 x NAS (Network Attached Storage) also on static IP What I want to do: I would like to make the server available from outside the network, for example from your house. The problem is that Im not really sure how to do this. I have tried following the steps on the instruction manual in Linksys but they do not seem to work, once I set it up as shown bellow, I loose internet and all hell breaks loose. Going into further detail, I would prefer if the network is changed as little as possible, by this I mean that all the computers stay networked within eachother and only the server is accessible from the outside the network. What I need HELP with: I have read around that it is possible to set a 1-1 NAT (I know where it is in the menu but have no clue what it does...) so that I can NAT a single public IP directly to a single private IP (in our case the server). But please, How do I do that? Or maybe an alternative?

  • Sparc Solaris 2.6 will not boot

    - by joshxdr
    I have a very old Sparc Solaris network that was working fine last week, but after a power outage none of the workstations will boot. The network looks like this: host A: solaris 2.6, shares /export/home to network by NFS host B: solaris 8, runs NIS server. Mounts /export/home/ by NFS. host C: RHEL5, shares /share to network by NFS. Mounts /export/home/ by NFS. I figured that the main problem was host A, since you need the home directories available for the other workstations to boot(?). Host A does not mount anything by NFS as far as I know. However, this workstation will NOT boot. The OBP bootup sequence looks like this: Boot device <blah> configuring network interface le0 Hostname <hostname> check file system <everything ok> check ufs filesystem <everything ok> NIS domainname is <name> starting router discovery starting rpc services: rpcbind keyserv ypbind done setting default interface for multicast: add net 224.0.0.0: gateway <hostname> <HANGS at this point> Is there some kind of debug mode so that I can get more detail as to why the workstation won't boot? Is my network structure inherently susceptible to power outage? Is there a way I can boot up to command line so I can at least turn off the NFS mounting?

  • DHCP Relay setup in ubuntu server

    - by jerichorivera
    I have a network appliance (QNO) that works as traffic load balancer and dhcp server. I would like to add a linux server in between the network appliance and the client computers. The linux server will be used to monitor bandwidth usage. My problem is I still want DHCP to be served by the network appliance so that load balancing will still work efficiently. We are afraid that if we setup the linux server as the DHCP server the network appliance will not be able to load balance the traffic if it only sees the linux server as a single client connecting to it. I've been searching all over for a tutorial on how to setup DHCP relay but have not found any. How do I setup DHCP relay on my linux server given there are two NICs attached to it, one connects the linux server to the network appliance and the other connects the linux server to the client computers. EDIT Router (DHCP) ---- [eth0] Linux Server (Relay agent) [eth1] ----- PC (network) Router IP is 192.168.0.100 eth0 is on DHCP eth1 is static 192.168.2.11 (if I need to change this I can) Tried to do dhcrelay -i eth1 192.168.0.100, but the PC was not getting any DHCP lease from the DHCP router. I might be missing something here.

  • Debian Wheezy IPv6 isn't configured with ifup post-up hook

    - by aef
    We recently set up a server on Debian Wheezy Beta 3 (x86_64) which has a native IPv6 connection. We configured the eth0 interface to get the IPv6 configuration through some post-up hook commands in /etc/network/interfaces. The result is, that after the booting the system up, there is only IPv4 and an auto-configured link-local IPv6 address configured on the interface, as if the command has never been executed. When we additionally place the commands after the call to ifup -a inside the /etc/init.d/networking init script, everything works as expected and we have a fully configured interface after booting up. This is quite an ugly way to configure the interface. What are we doing wrong with the ifup post-up hooks? Or is this a bug? The section from /etc/network/interfaces looks like this (IP-addresses changed): allow-hotplug eth0 iface eth0 inet static address 1.2.3.1 netmask 255.255.255.192 network 1.2.3.0 broadcast 1.2.3.63 gateway 1.2.3.62 dns-nameservers 8.8.8.8 dns-search mydomain.tld post-up ip -6 addr add 2001:db8:100:3022::2 dev eth0 post-up ip -6 route add fe80::1 dev eth0 post-up ip -6 route add default via fe80::1 dev eth0 I also tried it in this alternative way: auto eth0 iface eth0 inet static address 1.2.3.1 netmask 255.255.255.192 network 1.2.3.0 broadcast 1.2.3.63 gateway 1.2.3.62 dns-nameservers 8.8.8.8 dns-search mydomain.tld iface eth0 inet6 static address 2001:db8:100:3022::2 netmask 64 gateway fe80::1 What we added to /etc/init.d/networking: … case "$1" in start) process_options check_ifstate if [ "$CONFIGURE_INTERFACES" = no ] then log_action_msg "Not configuring network interfaces, see /etc/default/networking" exit 0 fi set -f exclusions=$(process_exclusions) log_action_begin_msg "Configuring network interfaces" if ifup -a $exclusions $verbose && ifup_hotplug $exclusions $verbose # Our additions ip -6 addr add 2001:db8:100:3022::2 dev eth0 ip -6 route add fe80::1 dev eth0 ip -6 route add default via fe80::1 dev eth0 then log_action_end_msg $? else log_action_end_msg $? fi ;; …

  • Wireless Access Point stopped working

    - by Alex Pritchard
    I have a simple LAN set up at home using a Linksys WRT54GSV4 as my primary router and an Encore ENHWI-2AN3 as an access point. I connect the Encore to the Linksys by running a cable from one of the Linksys LAN ports into the Encore WAN input. I originally configured this using the Encore setup wizard, setting the device up in AP Router Mode. It detected the input network and worked about as expected, creating a second network that used my primary network to connect to the internet. It worked fine for about 2 weeks, then abruptly cut out today. I checked to make sure the network was still live through the cable going into the Encore (provides internet when connected to a laptop directly) and that devices are still able to connect to the network being broadcast by the Encore. When I try to rerun the connection wizard on the Encore, I receive the message "No Services found in WAN port." The WAN Settings is no longer retrieving a dynamic ip from the line. I tried providing a static IP, assigning an IP address within the subnet range of my primary router that wasn't being used and pointing the Default Gateway to the Linksys IP, but this did not work either. When I plug the cable into the WAN port, an internet light comes on that is not lit when a live network is not connected. I've tried doing a hard reset on the Encore (held down the rest button until the lights flashed, reconfigured from scratch), but the WAN settings are still not detected. Also tried powering off and on the modem, linksys, and encore. Any suggestions would be appreciated!

  • Both screens always stay on after adding second monitor

    - by J.Merrill
    I had a single 1920x1080 monitor on a Windows 7 desktop PC and, per "power management" (not screen saver), the screen would go blank after 10 minutes. I added another monitor (2560x1600 if that matters) and since then, neither screen has ever blanked. I've tried turning on the "blank" screen saver, but that didn't help either -- I can go away for hours and when I come back, both screens are on. I've seen others with similar issues apparently caused by e.g. wireless mice that seem to move infinitesimally, but I've got the same wired mouse I had before. I can't understand why neither the screen saver nor power management is doing what it should to blank the screens, when "power management" used to do it when there was only one monitor. Maybe it doesn't matter so much with current LCD display technology (no "burn in") but doesn't a monitor use more power when "power management" hasn't turned off the display? Thanks for any suggestions.

  • Why is piping dd through gzip so much faster than a direct copy?

    - by Foo Bar
    I wanted to backup a path from a computer in my network to another computer in the same network over a 100MBit/s line. For this I did dd if=/local/path of=/remote/path/in/local/network/backup.img which gave me a very low network transfer speed of something about 50 to 100 kB/s, which would have taken forever. So I stopped it and decided to try gzipping it on the fly to make it much smaller so that the amount to transfer is less. So I did dd if=/local/folder | gzip > /remote/path/in/local/network/backup.img.gz But now I get something like 1 MB/s network transfer speed, so a factor of 10 to 20 faster. After noticing this, I tested this on several paths and files and it was always the same. Why does piping dd through gzip also increase the transfer rates by a large factor instead of only reducing the bytelength of the stream by a large factor? I'd expected even a small decrease in transfer rates instead, due to the higher CPU consumption while compressing, but now I get a double plus. Not that I'm not happy, but just wondering. ;)

  • Query specific nameserver for a particular domain upon VPN connect

    Some background: I have a work laptop with Ubuntu 9.10 on it. I have a small network at home where I've been running some basic services (for myself/my family) for 10 some years. In my home network there is a nameserver (Fedora) running Bind 9 with two "views". One view is the "outside" view and it provides name resolution (to the Internet at large) for email, a wiki, and a couple of blogs. The "inside" view provides name resolution (to the internal RFC1918 addresses of theses servers) as well as all the inside hosts, network equipment, ...etc. I connect with an openvpn client to my home network from outside (such as work). What I'd like to be able to do is resolve names on my internal network across this VPN (so I get the RFC1918 "inside" responses) without fully changing my resolver to the DNS server at my hose. For example, if I connect to the VPN from work, I can change my resolver (by editing resolv.conf) to the DNS server at my house (across the VPN) and then successfully resolve all of the inside DNS names on my home network. The issue I have with this is that now I'm no longer able to resolve "inside" names provided by my work's DNS servers (because I'm using my home DNS server). Alternatively, I can connect to the VPN and access my home severs via IP addresses directly, but this is inconvenient and causes issues with Apache name-based hosting (among other things). In the end, the effect I'm trying to achieve is as follows: When I connect to the VPN I automatically start sending DNS requests for *.myhomedomain.com to my home nameserver, but any other requests continue to go the the nameserver I was using before (the one I received on my company LAN via DHCP). When I disconnect the VPN, requests for *.myhomedomain.com go back to the local LAN DNS server (e.g. all requests are going there now). I'm looking for suggestion at to how this can be accomplished.

  • What can be done to improve time synchronization on networks with sporadic internet access?

    - by anregen
    I'm looking for advice setting up time servers for a very non-typical network. I support many closed networks that have occasional access to the internet. A network would get access most days for a few hours, but would frequently go 1-3 weeks blacked-out. The computers/servers on this network are mostly *nix-based, but not all the same flavor. The entire network is mobile, so when it connects, it will have very different hops/latency to internet time servers. The servers on the closed network are powered-off frequently (at least daily). Right now, my gut tells me to use NTP (because I hate re-learning all the stuff that someone else already got working pretty well). But I have several issues, and am looking for someone with experience in this type of strange situation. I currently have no solution in place, I'm simply letting the internal clocks drift. This results in errors of ~600s in a majority of networks. I have seen mismatch worse than 10,000s. Is there something "better" than NTP in this situation? I know NTP likes to have very frequent, consistent access to servers that give nearly identical answers. I won't have that. How many internal NTP servers should I configure, so that during periods of internet blackout, I have internal time that is consistent within the closed network? There is no human access. No matter how large the mismatch, the server(s) must attempt to correct itself. Discrete steps are very bad. No matter how large the mismatch, the correction must be "slewed", not "stepped". I understand that this could take many hours to correct.

  • Configuring WPA WiFi in Ubuntu 10.10

    - by sma
    Hello, I am trying to configure my wireless network on my laptop running Ubuntu 10.10 and am having a bit of difficulty. I am a complete Linux newb, but want to learn it, hence the reason I'm trying to set this up. Here's the vitals: It is a Gateway 600 YG2 laptop. It was previously running Windows XP, but I installed Ubuntu 10.10 in place of it (not a dual boot, I removed XP altogether). I have an old wireless card that I'm trying to resurrect. I haven't really used the card in a couple years, but it seems to still work, I just can't connect to my home's wireless network. The card is a Linksys WPC11 v2.5. When I plug it in, Ubuntu recognizes the network, but won't connect to it. My home network uses WPA encryption and the only connection type that Ubuntu's network manager is giving me is WEP and then it asks for a key -- I have no idea what that key should be. So, basically, I'm asking, is there a way I can instead connect through WPA? I've tried creating a new connection in network manager, but that won't work, it keeps falling back to the WEP connection and asking me for a key. I have tried to install the XP driver using ndiswrapper but I don't know if that's working or not. Is there a way to tell if: A) the card is working as it should B) the correct drivers are installed (again, I installed the XP one using ndiswrapper NET8180.INF, but I'm not sure what to do next) Any help would be appreciated. Thank you.

  • Unable to format/add a partition to Windows XP

    - by sma
    I recently add a 1T disk to an XP machine. I found the disk in the "disk management", I click "initialize" to init it, then creates a primary partition with size 950G, then select quick format to format the disk, the "disk management" will then complains: The disk configuration operation did not complete. Check the system event log for more information on the error. Verify the status of your storage devices before retrying. If that does not solve the problem, close the disk management console, then restart disk management or restart the computer. What could be the reason?

  • setting up vpn server

    - by Lock
    I need help in visualising how to setup our VPN box when we move to our new network with Telstra. We have a safe@office 500P, which has a public IP and a private IP of 192.168.19.2. It is physically connected to our router, which has 4 different interfaces, one being 192.168.19.1. On the VPN box, we have a static route to forward everything to 192.168.19.1 which is the router, and from there it works out where to go. Now, we are moving to a Telstra WAN and things are setup a little differently. Our head office router has only 3 interfaces- 1 is for the link to the switch that has the fibre connection (so our route to the internet and other branches), 1 is for our 10.10.20.x network and one is for the local branch network. I really have no idea how to set this up as with the new setup, we will not have a port for it to plug into on the router. Could I just plug it into the 10.10.20.x network? Would I have to give it a public IP or can we just forward through the ports that it would use? Another suggestion was to VLAN our switch into two networks- one for the 10.10.20.x network and one for the network the VPN currently sits on (192.168.19.x), and setup the router to trunk between the port and the switch. Not sure how to do this. Sorry VPN's are definitely not my strong suit. Any advice appreciated!
