ifconfig 2

[Scunningham99]

Hi

have a unix test box, netmasks is set correctly, and name in /etc/hosts

however machine cannot ping.

noticed in netstat -rn there is no devive for hme0().

ifconfig -a returns hme0 with ip 0.0.0.0.

can i type
# ifconfig 10.128.2.26 to set device with ip.
Basically what is the syntax for ifconfig +address!! and will a reboot hold these changes?

Thanks In advance

you should do the following:

# ifconfig hme0 unplumb
# ifconfig -a (you will not see hme0 anymore)
# ifconfig hme0 plumb
# ifconfig hme0 IP address broadcast + netmask +

(netmask + sets the network mask as defined in /etc/netmasks, broadcast + sets the broadcast address accordingly)

I forgot the last command :

# ifconfig hme0 up

to show all current devices do:

ifconfig -a

to add a device that exists in the /dev directory do:

ifconfig <device> plumb

to set the ip address of the device do:

ifconfig <device> <ip-addr> up

these changes will not stay there after boot ...

to make these changes stay put an entry in /etc/hosts that points at <ip-addr> then create a file called /etc/hostname.<device> and put the name associated with <ip-addr> in that file.

eg on my machine i have /dev/iprb0 so to add this device from scratch i would type
ifconfig iprb0 plumb
ifconfig iprb0 10.10.0.1 netmask 255.255.0.0 up

and in the files i would add
in /etc/hosts:
hosta 10.10.0.1

and in /etc/hostname.iprb0
hosta

i would need to make sure the netmasks were correct as well
