how to setup/config network
I have a new SUN Ultra5 box
I need to setup TCP/IP network
I have got IP, netmask, broadcast and gateway addresses
I don't know how to set tcp/ip up using commands
when I excute some ifconfig and netstat commands, I have the following outputs:
# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,
inet 127.0.0.1 netmask ff000000
hme0: flags=1000842<BROADCAST,RU
inet 10.251.11.109 netmask ffffff00 broadcast 10.251.15.255
ether 8:0:20:ff:e2:52
# netstat -rn
Routing Table: IPv4
Destination Gateway Flags Ref Use Interface
-------------------- -------------------- ----- ----- ------ ---------
127.0.0.1 127.0.0.1 UH 2 13 lo0
#
the interface to be setup is hme0
when I tried
route add default gateway 10.251.11.1
had error
gateway: bad value
I am sure that the physical network connection is OK as I swap the cable with the other machine and the other machine works OK
Can someone help please?
I need to use commands not GUI

What samri writes is correct except for the netmasks
file.
In this file you shoild enter the base network and the mask you you want to put on that network.
In your case the base network is a class A network (10.0.0.0).
This is maybe not the best choice for a small network, better to use one of 192.168.0 - 192.168.255 (reserverd for private networks not on the net or hidden behind NAT gateway.
Anyway, put 10.0.0.0 255.255.255 in the netmasks file
file.

# route add default <ip of default router/gateway> 1
If you are not sure what is your default router/gateway, you might want to check with your network guy.
And if you want to make it permanent there are a few files that you need to look at.
/etc/hosts
/etc/hosname.hme0
/etc/defaultrouter
/etc/netmask
in /etc/hosts
10.251.11.109 yourhostname
and in /etc/hostname.hme0, put
yourhostname
The entry in /etc/hostname.hme0 must correspond with <yourhostname> in /etc/hosts
in /etc/defaultrouter key in the ip address of your defaultrouter. For example
10.251.11.254
in /etc/netmasks
add a line :
<you network number> <your netmasks>
10.251.11.0 255.255.255.0
And then reboot your machine.
good luck
