  1. NAT

    Find the MAC address associated with the public IP. If the router's WAN has not been cloned, you can determine who manufactured the router. Then you can figure out what the default LAN IP is and the default DHCP scope. You can assume the first few IPs in the scope have been assigned to the computers on the LAN... This also assumes the user has not changed the LAN IP, adjusted the DHCP scope, and has their computers setup to obtain IPs automatically. Even with this info, there is not much you can do... NAT routers block all unsolicited inbound requests and use private IPs on the inside. Unless a port has been forwarded to an internal IP, you won't be able to get in.
  2. You're absolutely right. If I understood Linux and * enough to compile it on my own, I would probably have the answer. Baby steps...I admit, I'm a just n00b "dinking" around. Gotta start somewhere though....
  3. I'm trying to figure out how to change the festival voice in asterisk@home. I want to use the female voice included with @home. Can anyone provide me with some info on this? Is there a specific config file to modify? I looked in the asterisk festival.conf file, but didn't see the voice declared. If that's where you do it, I don't know the syntax to use. I also tried festival>(voice_name_of_the_voice), but it didn't seem to work... Any help would be appreciated.
  4. I finally found some time to look in to this topic some more. Looks like I need a bluetooth channel for Asterisk, which doesn't exist yet... Has anyone messed with this?
  5. Can you point me to some info that explains why/how double nat is bad? Not trying to challenge you, I'd just like to learn what you know. Thanks!
  6. I have a cell with BT support, a BYOD TA (open), asterisk, and a BT dongle. My phones connect to the TA. The TA connects to asterisk. The comp running asterisk has a BT dongle. My celli can pair with the dongle. Is it possible to use my phones at home to dial out and receive calls from my cell phone? If I place a call on a phone connected to the ta, id like asterisk to associate with my cell and call out. If I receive a call on my cell, Id like asterisk to ring the phones on my TA. Does that make sense? I think Uniden might make a phone like this... I really didn't look to hard for the answer on my own before posting... sorry. Call me a n00b then kindly point me in the right direction
  7. "If you wanted just an AP, should've bought one" Not necessarily... You can turn a router in to an AP, and its quite easy. Disable DHCP and don't use the WAN. Now you have an AP + switch with a bunch of extra functionality that you can use later. Double NAT will segment the LAN side of the Netgear router from the LAN of the Linksys. It sounds like you want what's on the LAN of the NG to talk to the rest of your network. If you want to take advantage of the speeds offered by your new wireless gear, then you really don't want to do double NAT. Here is what you should do: Start by unplugging the network cable to the Netgear. 1. Determine the LAN IP range on the Linksys. On a computer connected to the LAN, enter IPCONFIG from a command prompt. I think the default is for the network address on Linksys... 1.1 for the LAN port. You will be assigning the LAN IP of the NG an address in this range, so figure out a free address. 2. Connect wirelessly to the Netgear. From a command prompt, enter IPCONFIG/RELEASE, then IPCONFIG/RENEW. Note the Default Gateway address. Thats the LAN IP of the netgear. Enter that address to access the web config. If you can't pull an IP, either DHCP is off on the Netgear, or you don't have a good "physical" connection. My guess is the latter. 3. From the Netgears config, disable the DHCP server (you will use the Linksys for as DHCP). 4. Assign the Netgear a new LAN IP. Give it a free address on the same network as the Linksys ( ??). This step isnt really necessary, but it will allow you to access the config again from a computer connected to your network. Remeber this address. You will use it to get back in to the config of the NG. 5. From a LAN port on the Linksys, connect to a cable to the LAN port on the Netgear. Check for solid link lights. 6. Connect wirelessly to the Netgear. From a command prompt, enter IPCONFIG/RELEASE then IPCONFIG/RENEW. You will obtain a new address from the Linksys DHCP server. 7. ENABLE WPA! 8. Enjoy the improved performance on your wlan. I'd like to add that double nat can be useful. Use one LAN as a "DMZ" (P2P, network testing, honeypot, shit you dont care if its compromosed), and the other for your "protected" network. Hope that helped...
  8. Sure you could use it in your home network. Probably overkill, but it's possible! I'd say the main beneift is that it is way more robust that your typical Linksys or D-Link NAT router, but that can make it more difficult to configure. The Cisco router has better processing power, QoS support, and supports more dynamic routing protocols giving you more control of the traffic on your network. Most residential routers don't support QoS and primarliy run NAT. They may support static, RIP1 and RIP2 routing. The Cisco router is configured via a command line and NAT routers are configured via a pretty web interface. Have you tried to log in to it? Is it locked down with passwords? I'll take it if you can't use it
  9. If you have a networked machine, you can arpspoof and run msgsnarf. I believe you can find both tools on the knoppix-std live distro. I've olny tested with msgsnarf once just to see how it worked. I can't remember if it, alone, can log the messages. Only use these tools if you have permission to monitor the conversations.
  10. Use the latest drivers from Disable any other network adapters installed on the machine. After you connect wirelessly, can you pull an IP? Can you ping your AP? has the Atheros driver, but I don't think that will do much good in 98... 2000 and XP have built in wireless utilities, and it will work well in those OSes. For Linux, I think you want the MadWiFi drivers. Should work out of the box in knoppix.... google madwifi for more info Try iwconfig and see if it list ath0. If so, the drivers are there and you just need to configure your wireless settings.
  11. Yes and Yes. Not necessarily. You could always access the site by entering your public IP in a web browser.. If you have a router that supports DDNS, Check out (free) and read up on Dynamic DNS. DNS is what resolves domain names to the IP where its being hosted. dyndns will let you set up a friendly name, like, and map that to your public IP address. You will need to configure your router with your DDNS credentials. If your WAN IP changes, it will notify dyndns of the change and will get remapped to your new IP. If you are behind a router, you are going to need to forward port 80 (default) to the private IP of the computer running the web server. Make sure your ISP doesnt block port 80... Hope that helps.
  12. the more connections the better ← Dont do double NAT (LAN to WAN)... it could cause some headaches if you are port forwarding. Choose which one you want to be the router. The disable DHCP on the other, check to make sure the LAN IPs of the routers are unique(but in the same subnet), and connect LAN to LAN. Then you got a router and a switch with a bunch of features you arent using.
