PostPosted: Wed Dec 29, 2004 11:13 pm    Post subject: Setting up static ip [SOLVED] Reply with quote

I have been trying to use a static address and my ISP says I have one.Here is what I get after dhcpcd eth0 but it takes a long time,and I have to do it a few times.
Code:

gentoo david :/home/david# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:0C:F1:E4:80:F6 
          inet addr:192.168.1.97  Bcast:255.255.255.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:f1ff:fee4:80f6/64 Scope:Link
          UP BROADCAST NOTRAILERS RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1839289 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1357373 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:2367343230 (2257.6 Mb)  TX bytes:97935232 (93.3 Mb)

gentoo david :/home/david# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
loopback        localhost       255.0.0.0       UG    0      0        0 lo
default         launchmodem     0.0.0.0         UG    0      0        0 eth0

I have tried this in /etc/conf.d/net
Code:
(For static IP)
iface_eth0="192.168.1.97 broadcast 255.255.255.255 netmask 255.255.255.0"
gateway="eth0/192.168.1.0"
What am I doing wrong?

Why are you trying to dhcp if you have a static IP address? Just plug in the numbers your ISP has provided into /etc/conf.d/net and restart /etc/init.d/net.eth0

Because the numbers they provided don't seem to work and they have no clue about linux,I'm doing something wrong or the numbers are wrong.I'm going to ask them the numbers again.This is my first time setting up a static ip so I have no clue except for the doc's and some help from the nice people on this forum.

i have one of those westell dsl modems too, but it's really a NAT router

if you want to have your pc be directly on the internet, without the modem managing the firewall, you have to use the web interface for the modem to set up the single static ip configuration. so open up your browser and go to http://launchmodem and turn on the static ip (it should be in the configuration drop down menu if you have the same model i do).

No launchmodem not found, here is my /etc/resolv.conf
Code:
nameserver 192.168.1.254
nameserver 192.168.1.254
search launchmodem.com
domain tux

Should I just keep doing it the way I have been and forget about the static address?

i saw launchmodem was your default gateway from the route output you posted before, odd that it didn't find it. can you get on the internet at all? judging from the resolv.conf the modem's ip should be 192.168.1.254, so try to browse to that

I have the Westell ethernet modem with bellsouth also. Before i put in my router, I used rp-pppoe for my connection even after I changed to the static ip and it worked like a charm.

you have a static ip from your isp. the modem acts as a router at the same time and that's what it uses to get online. the modem also has dhcp/dns services, which is what your computer attached behind it actually sees, and gets its address from.

if you want you can set gentoo up to use a static ip to communicate with the modem, which has the static ip from your isp. so to people on the outside, your ip address will always be 65.12.210.216, but you can set your local ip address in /etc/conf.d/net to something like 192.168.1.5 and set the gateway and resolv.conf information to 192.168.1.254 (the modem's internal ip)

it's just a matter of personal preference, since the modem is all your isp sees

Thanks for the replys,I can't get it to work
Code:
gentoo david :/home/david# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:0C:F1:E4:80:F6 
          inet addr:192.168.1.97  Bcast:255.255.255.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:f1ff:fee4:80f6/64 Scope:Link
          UP BROADCAST NOTRAILERS RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:196 errors:0 dropped:0 overruns:0 frame:0
          TX packets:202 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:170168 (166.1 Kb)  TX bytes:20538 (20.0 Kb)

If I use these numbers it will work sometimes,I never reboot so I'm not going to worry about it,just wanted to be able to do it.I just don't seem to get it :idea: If I put another inet addr It says it is connected but it is not,then if I try ifconfig eth0 up it says network unreachable.I can allways run dhcpcd eth0 but it takes awhile or I have to redo it a few times to get connected.thanks again

Code:
inet addr:192.168.1.97  Bcast:255.255.255.255  Mask:255.255.255.0


Humm, setting the broadcast adress for your adapter to the whole internet (or actually all networks) seems a little odd idea, esp, when your netmask ist /24

Bcast should rather read 192.168.1.255, in case the Net-Mask is right.

Aside from that: did you setup the gateway properly (which should be your modems ip on the internal interface) ?

Thanks, the modem ip is 65.12.210.216 here is the other numbers my isp gave me;
Your static ip is - 65.12.210.216
Your subnet mask is 255.255.255.255 and the default gateway is 192.168.1.2. We apologize, but we're not quite sure what you're asking for when you also askedfor the Broadcast.Should I try;
Code:

ifconfig eth0 192.168.1.97 broadcast 192.168.1.255 netmask 255.255.255.255 up
route add default gw 65.12.210.216

Not sure of the syntax?

ifconfig eth0 192.168.1.97 broadcast 192.168.1.255 netmask 255.255.255.255 up
route add default gw 192.168.1.2

Shoudl read like that .... I assume .... in /etc/conf.d/net

iface_eth0="192.168.1.97 broadcast 192.168.1.255 netmask 255.255.255.255"
gateway="eth0/192.168.1.2"

And restart neth.eth0 after chnign /etc/conf.d/net

good luck .....

I was going to try it manually,so I don't have to reboot to get /etc/conf.d/net to be read.Should my default gateway be my modem address 65.12.210.216 or the one they gave me,thanks again

The one they gave you, well, as soon as you edit the conf.d/net file as I described...

you can run /etc/init.d/net.eth0 restart and everything will be set up - of course you can aswell enter the command by hand :wink:

SUCCESS :D
Thanks DarKRaveR and popcan here is what I ended up with,I learned something today
Code:
# We can also specify a broadcast
#config_eth0=( "192.168.0.2/24 brd 192.168.0.255" )
config_eth0=( "192.168.1.97 netmask 255.255.255.0 broadcast 255.255.255.255" )
gateway="eth0/192.168.1.254"
I quess subnet mask is broadcast? from my isp
Your subnet mask is 255.255.255.255
