I found the answer on the Engenius site, which directed me to use a null modem cable to Telnet into the bridge and perform a reset. All is well now.

Need user manual for a Lanex/Verint netDVR. Also need the procedure to reset the netDvr to its default status. Thanks in advance for your assistance.


Let me guess - you aquired a netDVR with no hard drive and put one in and it doesn't work. The hard drives are encoded with some data that is specific to Lanex, so you have to buy the hard drive from them at a large markup. This is my only pet peave with Lanex as otherwise they are one of the best on the market. Do you have the application to talk to the netDVR? If you do then the default password is 'admin'. this should let you in to make changes to the configuration.

DHCP Server configuration in Linux


Linux is a UNIX based operating system. It is a server operating system. REDHAT Linux is Enterprise version of Linux. Now a day's Most of corporate sectors use red hat Linux as server in their company because it is secure very much.

Full form of DHCP "Dynamic Host Configuration Protocol. DHCP server assigns IP addresses and other network configuration information like subnet mask, broadcast address, etc to computers on a network. The DHCP assignments are the following.

Lease Request: Client broadcasts their request to DHCP server with a source address of 0.0.0.0 and a destination address of 255.255.255.255.
IP lease offer: DHCP server replies with an IP address, subnet mask, network gateway, name of the domain, name servers, duration of the lease and the IP address of the DHCP server.

Lease Selection: Client receives offer and broadcasts to al DHCP servers that will accept given offer so that other DHCP server need not make an offer.

The DHCP server then sends an ack to the client. The client is configured to use TCP/IP. Lease Renewal: When half of the lease time has expired, the client will issue a new request to the DHCP server.

Installation of DHCP server: First of all while install the RedHat Linux enterprise version server be careful about the ports and the services must be turned on. To create DHCP server in Linux first download DHCP RPM package and install with "rpm-ivh" command. Where I have done it there I have create YUM server, so easily I have download and install it by YUM (yum install dhcp version). DHCP package will locate in /usr/share/doc/at Linux file system. I copied the DHCP's files from /usr/share/doc/ to /etc/dhcpd.conf.. Then I started to configure the dhcpd.conf file to route the DHCP server in there local network. I have open the configuration file with "vi" command. Then commented out the lines from "default gateway to option netbios" because system don't read the commented lines. After that I set the range of IP address in dynamic- bootp of their local assumption of system. I have change the "next-server" with the dhcp server name and have also change the fixed address with the dhcp server IP address (end range of dynamic IP). It is very easy job to configure DHCP server. After configure the .conf file of dhcp just turn on the service with "chkconfig" command and restart the dhcp service. After that entire job I reboot the system. And after rebooting of server I turned on the other client system. While startup the client system without static IP address all of those picked up IP from dhcp server and going on successfully. I have prefer the command line mode to do the total job.
The DHCP server configure file is following:

ddns-update-style interim
ignore client-updates

subnet 192.168.1.0 netmask 255.255.255.0 {
# The range of IP addresses the server
# will issue to DHCP enabled PC clients
# booting up on the network

range 192.168.1.201 192.168.1.220;
# Set the amount of time in seconds that
# a client may keep the IP address

default-lease-time 86400;
max-lease-time 86400;

# Set the default gateway to be used by
# the PC clients

option routers 192.168.1.1;
# Don't forward DHCP requests from this
# NIC interface to any other NIC
# interfaces

option ip-forwarding off;

# Set the broadcast address and subnet mask
# to be used by the DHCP clients

option broadcast-address 192.168.1.255;
option subnet-mask 255.255.255.0;

# Set the NTP server to be used by the
# DHCP clients

option ntp-servers 192.168.1.100;

# Set the DNS server to be used by the
# DHCP clients

option domain-name-servers 192.168.1.100;

# If you specify a WINS server for your Windows clients,
# you need to include the following option in the dhcpd.conf file:

option netbios-name-servers 192.168.1.100;

# You can also assign specific IP addresses based on the clients'
# ethernet MAC address as follows (Host's name is "laser-printer":

host laser-printer {
hardware ethernet 08:00:2b:4c:59:23;
fixed-address 192.168.1.222;
}
}
#
# List an unused interface here
#
subnet 192.168.2.0 netmask 255.255.255.0 {
}

Get error 323 - restore the factory defaults for your router - reset router to factory - cannot access new router or gateway


Once you've reset it to factory defaults, you'll probably need to establish your initial connection to it using a Cat 5 cable - possibly crossover. Then you can visit it's internal web page (address in manual) to enable WiFi, etc.

What model was that?

How do i configure my dlink 302g modem to my new ISP's settings?


Hi Nitangel
Before proceeding with modem installation you need to gather your connection details from your Internet Provider. You will need to know or find out the following information about your new ADSL connection from your Internet Service Provider:

Connection Type:
PPPoE
PPPoA
Bridge RFC1483

Default IP address: 10.1.1.1 (USB 10.1.1.2)
Username: admin
Password: admin

· Username / password (PPP connections only)
· IP address / Subnet Mask / Default Gateway (Bridge connections only)
· DNS IP Addresses (optional)

To set up, log into the modem using your WEB browser: type http://10.1.1.1 in the address bar and press Enter.
Enter username 'admin' and
password 'admin' (default setting).

Go to Quick Configuration page.
Set Refresh Rate to "No Refresh".

If it is a PPPoE or PPPoA CONNECTION:
Select Operation Mode: PPP.
In the Connection Type drop-down menu select PPPoE or PPPoA profile.
Enter username and your password.
Select CHAP under Authentication Type (check with your ISP if not sure).

If it is a BRIDGED RFC1483 CONNECTION:
Select Operation Mode: Bridge. If you do not see "Bridge" options please update your modem's firmware at http://www.dlink.com.au/tech/
Select LLC or VC Mux as suggested by your provider.

Make sure your VPI/VCI is set according to your ISP requirements:

Click on "Save & Reboot" to save settings.

Then give modem a minute or two to reboot and reconnect. Restart your computer and you should be able to access the Internet.

You do not have to run any login client on your computer or router because your modem logs to your ISP automatically.

Hope this information helps if I can help further let me know.

How to protect my belkin 54g wireless connection from intruders. Please help me with that


There is no sure way to stop intruders - if they want to get in they can and will.

However in saying that you can certainly be smarter than the average jo driving around an estate looking for open wireless routers.

First thing first, always change the default password for the router (admin, password). If you can, change the username also (from admin to something else).

Secondly I would recommend that you enable some kind of WPA (or WEP) protection. This basically means that anyone attempting to connect to your wireless will require a "password" to connect to you. The more bits the password has the longer the password is and usally the harder it is to crack (via a brute force attack).

Thirdly - Hide your SSID. All routers by default show to the world they exist. If someone doesnt see it broadcasting generally they wont know its there.

Forthly. I would recommend setting up access lists. On every network card (be it wired or wireless) has a unique identifier called a MAC address. An access list restricts which MAC addresses can physically connect to your router. To find out your mac address click Start - Run. Type CMD. Type IPCONFIG /ALL

Fifthly - This may require a bit more fiddling around between both the router and PC's but may be worth it in the long run. Most routers broadcast whats called DHCP. This is what gives you an internal IP address. If your router allows you setup the DHCP settings to something incorrect EG: Different Subnet mask, DNS settings, Default Gateway. Then setup your home PC's manually to the correct settings. This way if someone does end up cracking your router it will throw another curveball at them as they will not be able to surf the net, view your shared files, without more fiddling.

As far as PC based security goes, I would suggest that you check any shared files or folders you may have and disable, setup how many people can use it at once, permissions etc for them. Best way to check would be Click Start - Run. Type \\127.1.1.0 <- This will connect to your pc via the network.

Wireless connection to netgear Rangemax Wireless router, see's router but won't connect?


Check your router to see if the DHCP server is enabled. If not, then either enable that, or manually assign your wireless network card an IP etc.

Also check the router to see if it is set to have access restrictions like mac address filtering. Even with the right IP setup on your wireless card, you will still need to be authorised in the mac address list of the router to gain access.

If you don't have another computer there, or a lan cable to connect to the router, then do a reset to default and it should have most if not all of the security features off and the DHCP server on.

Wireless internet hookup


What seems to be the problem of your wireless internet?

I have a new wireless router and the set up cd cant find my router even tho i can access the internet through a wire


if you have a wireless router that has some lan ports.. there is no problem..
  1. You should connect an ethernet cable from wall jack directly into the WAN port on your router/access point.
  2. We recommend that you have some kind of encryption enabled- at least WEP, and preferably WPA or WPA2 which are far more secure than WEP.
  3. We also recommend (for increased security) that you enable MAC filtering. This feature allows you to identify which wireless cards the router will "speak" to, and it can specify that your router ignore all other ethernet cards. This ensures that only computers you approve of can use your access point. You can find your MAC address by clicking Start -> Run, typing "cmd", clicking "Ok", and then typing "ipconfig /all" in the console window that pops up. Your MAC address is listed next to Physical Address. If you have more than one network adapter, such as an ethernet and wireless, you probably have more than one MAC address. Make sure to use the one from the wireless adapter.
then:
  • Open Internet Explorer (with the computer connected to the Router)
  • Enter 192.168.1.1 into the Address Bar, push Enter
  • Leave the User Name field blank
  • Under the password field enter “admin
  • Click “OK
some routers have a quick set up... try that firts.. then.. you could get to make your connection a bit secure... by changing the password.. its really simple.. just tour around the options.. and if you need help, just post your problems
