60.30 Network Example Configurations
We present here some example network configurations. The numbers will
only make sense for very specific locations and you will need to
obtain your specific addresses from your System Administrator. We
illustrate these through the contents of
/etc/network/interfaces but it is advisable to use
Applications\(\rightarrow\){System Tools\(\rightarrow\){}Networking} as discussed above
to change the contents of this configuration file.
The simplest configuration uses DHCP to automatically obtain network information from a server that allocates addresses:
velox was initially set up to allow DHCP allocation of the IP
address. The DHCP server delivered the appropriate information as
demonstrated in /var/log/installer.log:
got dhcp offer
HOSTNAME: requesting velox
ip: 183.44.70.122
next server: 0.0.0.0
netmask: 255.255.255.0
gateway: 183.44.70.177
dnsServers[0]: 183.44.72.1
numDns: 1
domain: togaware.com
broadcast: 183.44.70.255
network: 183.44.70.0
configured interface eth0
The network has been successfully configured using DHCP/BOOTP. A manual configuration requires the information to be specified:
auto eth0
iface eth0 inet static
address 105.229.8.151
netmask 255.255.255.192
broadcast 105.229.8.191
gateway 105.229.8.190A computer with a 3Com 3c905 ethernet card:
eth0: 3Com 3c905 Boomerang 100baseTx at 0xfc80, 00:c0:4f:f7:02:bf, IRQ 10
8K word-wide RAM 3:5 Rx:Tx split, autoselect/MII interface.
MII transceiver found at address 24, status 7849.
Enabling bus-master transmits and whole-frame receives. You can check that the eth0 interface is functioning:
# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:C0:4F:F7:02:BF
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0

TX packets:21 errors:0 dropped:0 overruns:0 carrier:21

Interrupt:10 Base address:0xfc80 A computer with a SMC91C92 Ethernet network card. I had to configure
the appropriate kernel module to have this card recognised. I used
the modconf command to do this, select the Net
modules and select the smc9194 module. Configuring this
succeeded, returning the following message:
