Linux File Sharing, Client Connectivity
You may need to be aware of how to
access network-shared files in a Linux network for the Network+ exam.
By default, Linux uses the standard
UNIX file-sharing protocol NFS (Network File System, developed
by Sun Microsystems) for its file sharing activities. Client Linux
machines can connect to network file resources by using the mount
command from the clients command line, specifying tnfs,
to tell Linux to look for a network file share by that name, as in:
mount tnfs my.srv.com:/shareddir
This will provide access to the shared
resources shareddir on the server my.srv.com, for the local
To share files between a Linux
machine and a Windows machine, you must either install
Samba on the Linux box (which allows the Linux box to speak the
Windows File Sharing protocol), or install NFS on the Windows box
(which allows the Windows box to speak the NFS protocol).
Multiple NIC cards
Multiple ISA based NICs can be configured by using the following lines in the /etc/conf.modules file:
alias eth0 ne
alias eth1 ne
Use PCI NICs
PCI has been available long enough to not waste time/energy on an ISA card for any O/S. Use PCI wherever possible.
If you didnt take the advice to use PCI use:
netconf command for old hardware
It is common to see old hardware getting new life as a proxy server or firewall using LINUX. As we mentioned earlier in discussing what an IP Proxy server is, this typically means two more NICs are installed in the old box. If the O/S is not seeing both eth0 and eth1, use netconf from a command line, selecting the enabled box in the device tab and configure each card separately.
To set up a NIC from the command line in Linux, use the ifconfig command. ifconfig is also used in Linux (and UNIX) environments to display information about a network interface (such as IP address, subnet mask, etc.), similar to ipconfig or winipcfg in a Windows environment
Do not confuse ifconfig with the Windows command IPCONFIG, which displays TCP/IP configuration information.
