start static ip from comand line

[slackeast]

Ok, I know how to restart my dynamic ip over command line.

ifconfig eth0 down
ifconfig eth0 up

dhcpcd eth0

However, when I try to static.


ifconfig eth0 192.168.0.112 netmask 255.255.255.0 broadcast192.168.0.255 up

I try to access the internet but can't.

so I think I need a nameserver so I add

route add default gw 192.168.0.1

SIOCARDDRT: Network is unreachable

Any ideas what I'm doing wrong. I can always just start up /etc/init.d/net.eth0 but I'm just curious. J

of course it is quite long, but taking a look at the script to which /etc/init.d/net.eth0 points to may clear things up.

[slackeast]

ya i looked through the script......from what I understood, which is probably very little, i couldn't figure out how they get the gateway in the routing table. I did see the nameserver correctly in resolv.conf. J

Look up an example very much easier for your day to day

This is your /etc/conf.d/net file

Code: Select all

dns_domain_lo="yourdomain"

config_eth0=( "10.0.0.2 broadcast 10.0.0.255 netmask 255.255.255.0" )
routes_eth0=( "default gw 10.0.0.1" )
dns_servers_eth0="200.45.191.35 200.45.191.40"

And this is the way you can bring up your network

Code: Select all

/etc/init.d/net.eth0 start

Now, you'll need to edit the first file just once.

ifconfig eth0 inet 192.168.0.112 netmask 255.255.255.0
route add -net 192.168.0.0 netmask 255.255.255.0 eth0

These two commands suffice to get network going. If you want domain names to resolve put a valid nameserver into /etc/resolv.conf. That's it. Of course, this won't survive reboot.

ifconfig eth0 inet 192.168.0.112 netmask 255.255.255.0
route add -net 192.168.0.0 netmask 255.255.255.0 eth0

These two commands suffice to get network going. If you want domain names to resolve put a valid nameserver into /etc/resolv.conf. That's it. Of course, this won't survive reboot.

That adds no default gateway or any kind of route to the internet or another network.


This guy just needs to do as daschapa suggests and use the config file /etc/conf.d/net, I can't really think of a good reason why not to use the config file If the user regularly needs to switch from dhcp to a static IP address they should just create two config files and symlink the one that's needed to /etc/conf.d/net before restarting /etc/init.d/net.eth0
