Re: technical problem

Quick reply, I'm leaving on a long drive...

Has #9 worked or is this a new install?

Either way you must be sure that firewalls (if any) are set right, priviledges and other security are set, and if a server, the program itself must recognize users/computers.

When pinging, it only proves that the CPUs see each other electrically.

Besides the above problems it could be a protocol/driver problem or such.

Yes it could be the NIC as suggested earlier. But I am a proponent of not running out and buying anything until we hit a bump while diagnosis.

The more inofmation you give the easier it is to diagnose. So yes, knowing what OS, server software, firewalls, etc are inportant to know. What hub/switch? Wireless router?

If your more specific I can be with an answer.

Re: technical problem

Is there a server involved and what os are you running on all the machines, If all machine are equal, you might want to replace the Network card

When sending the ethernet signal from my modem to my GreyFox F7810 home system through the wall, I sometimes get the 100mbps download that I should be getting but other times I only get 10mbps, how ca

how are you checking this speed.
the speed you appear to be quoting at the computer is the speed the lan network socket is running at. it's probably rated at 10/100
some peripherals only have a 10M interface hence you only get a 10M reading and sometimes will slow the whole network down.
not sure what you mean when you send your network 'through the wall'. if that's using a powerline adapter, the connection between them often only runs at 10M. I've got 500m powerlines and they're often down to 10M, sometimes 100M but not very often.

Set up a home office LAN which access internet through USB wireless gadget

The following networking job I have done in this Lab. It is enough for a small office to access or transfer file Printing and access of shared Internet in different type of operating system.

We have recently set up a home office (small laboratory) LAN. All the computers access the internet through a USB wireless (CMDA) dongle. The USB stick is Huawei EC168C and internet service provider is Reliance Infocom (India). But any USB internet dongle can be use to share internet in a LAN in the following way. And you don't need a router for that. In the areas where ISP cannot give wire line internet connection this type of USB wireless sticks are really helpful for home office.

Basic LAN Connection:

Here this lab has 4 PCs. One Windows XP, another Windows Vista starter and two RedHat Linux server systems. Here in this lab I have done the basic LAN connection using cat5 cable & RJ45 connector and an 8 port hub. I have connect the two windows based OS. Using cross cable I have connected two windows system with the hub. Then I put static IP address in Ipv4 of TCP/IP. After that I set workgroup name to join in a workgroup in windows PCs. Then I tried to ping the systems, and it was pinging. Then I have setup a home or small office network in both windows system. That I have enabled the Printer sharing. After that I can share file, data and printer through the system gateway.

Now I have to connect other two Linux PCs in this network. With same cross cable I have joined the both Linux system with the hub. Then to detect the Ethernet device I have put down "DEVICE=eth0" entry in /etc/sysconfig/network-scripts/ifcfg-eth0 file. Then I set IP address in Ethernet device in network configuration in graphical mode (or System-config-network in text mode).After doing this job I restart the network service with "service network restart" command. Then I am trying to ping the systems to one another, And It was pinging.

Now Linux system can access with each other and files also shared through SSH, Telnet,FTP using process and command.

Linux Configuration:

I have configured the Linux system in the following way. First I have set the host name in /etc/sysconfig/network file by VI editor. Next I have edit /etc/sysconfig/network-scripts/ifcfg-eth0 file with "Device=eth0" to detect the Ethernet device. After that I have put the IP add in network configuration file and Restart the network service. To keep the eth0 on permanently I also use the chkconfig command.

After doing this job File sharing can be possible through network file sharing (Nfs). I have install Nfs package & shared the nfs dir by editing exports file. Then I am trying to automount the NFS dir by automounting process. So that I put automounting entry of nfs file in fstab file. After that it's automounted in other system's mount location.

Windows & Linux Networking:

Through basic LAN both OS can only ping each other. To share file or data samba server (a client server in Linux) must be configured in Linux system. So I Install smb rpm package from yum repository. Then I have Configure the samba/smb.conf file. I put the Workgroup name on Workgroup column of samba/smb.conf file. Then I Set the network IP without host to route in network in Host allow column. At last I put down all details of Samba dir, users at the end of the configuration file set the samba password. After that I restart the samba demon to up the samba server. Now files can shared through samba server. In windows I Set the workgroup name pairs with samba server and also set username and password same as samba server. Now I trying to send or access file through samba in both OS and it happened.

USB Net Connect:

Here in this lab workers are use internet from an Usb net connect. So it must be shared in Network. It is too fast so shared internet can be access easily. In Windows XP system I connect the USB netconnect & share it in network. IF all the network setting is ok then all the systems can access shared internet through gateway. Here all users use this shared internet now.

Access of Another System:
VNC Server & Viewer is software through which we can access of another system easily. I just install the software & set the password. Then I run the vnc server. After that I Put the IP add of vncserver from vncviewer of another system and type the password & start access the vnc server system. It can be access form WAN also. I just Run the Vnc server and connect the internet and I got a Wan IP add provided by ISP.

One static IP has internet. how on a LAN?


You need two network adopters in your system.
Connect Internet connection in first Network card and from the other network card give it to your Switch or hub
If you are using XP system you can use Internet connection sharing to share the internet in your LAN systems.
Follow the steps to enable using ICS

1.Enable Internet Connection sharing in the LAN properties in the first network card.
2.Now your second network card automatically get an IP address in the range of 192.168.*.* series
3.Connect other systems in the LAN and make sure the system has selected Optain IP atomatically from DHCP.

You are all set.

There is also an advanced way to setup this .
Install IPCOP firewall in a system with two network cards and u can share the internet with the firewall settings

How a conect to internet

METHOD 1 - Using Internet connection using DSL or cable connection.
1st. If you wish to connect to the Internet with a LAN cable or a wirelessly and if your computer doesn't have a LAN card or wireless LAN card you need to purchase a LAN card (to configure the wireless router) and if you want a wireless connection you will also need to purchase a wireless LAN card.
2nd. You need to select an Internet Service Provider in your area with a plan and cost to suit your requirements.
3rd. You need to decide what type of broadband connection you need, DSL or cable modem with or without a built-in wireless router, the Internet Service Provider can assist you with this.
5th. The Internet Service Provider can supply these items or advise you what make and model to purchase. They will also provide information on how to connect and setup your Internet connection.

METHOD 2 - Using USB wireless adapter that plugs into the laptop's USB port. It doesn't need a wireless router or a cable or DSL modem.
This is used mostly on laptop computers which allows Internet access anywhere the Internet Service Provide has a wireless transmitter. It uses the G3 mobile system.
This type of service usually costs more and again you need to select an Internet Service Provider that can provide the wireless coverage, the plan and costs that suit your requirements.
Installation and setting up information is supplied by the ISP.
