Title: [SOLVED] How to set permanent ip address in Tiny Core Linux?
Post by: Adam on July 31, 2013, 07:17:26 PM

Hi all, ifconfig is a temporary solution to set an ip address to linux/unix. I was wondering to make this permanent on Tiny Core Linux so I don't have to re configure it again every time I reboot this machine.

Thanks in advance

In my /opt/bootlocal.sh, I have this entry:

Code: [Select]

/opt/eth0.sh &
My /opt/eth0.sh:

Code: [Select]

#!/bin/sh
pkill udhcpc
ifconfig eth0 192.168.0.3 netmask 255.255.255.0 broadcast 192.168.0.255 up
route add default gw 192.168.0.1
echo nameserver 192.168.0.1 > /etc/resolv.conf
this has been done via gui
ControlPanel -> Network

opt or opt/eth0.sh has to be listed in /opt/.filetool.lst.

Thanks for your reply. I’ve tried it but didn’t work

Configuration on the following file will be reset once I rebooted the TC

Hi Adam
You need to run a backup:

Code: [Select]

filetool.sh -b

Thanks Rich. I've run the backup and after reboot, all the config are still there.

BACKUP CONFIG

Code: [Select]

root@box:/# filetool.sh -b
Backing up files to /mnt/sda1/tce/mydata.tgzDone.

VERIFY CONFIG AFTER REBOOT

Code: [Select]

#!/bin/sh
# put other system startup commands here
/opt/eth0.sh &
root@box:~#
root@box:~# cat /opt/eth0.sh
#!/bin/sh
pkill udhcp
ifconfig eth0 192.168.10.15
root@box:~#
Unfortunately, instead of getting fix ip 192.168.10.15, I’m still getting dhcp ip 192.168.10.101.

VERIFY CURRENT IP ADDRESS

Code: [Select]

root@box:~# ifconfig | grep dd

To skip the initial dhcp request at boot use the boot code of nodhcp

-rw-r--r--    1 root     staff           50 Aug  1 00:54 eth0.sh
Second be sure /opt/eth0.sh is made executable.

Hi Misalf
Read my previous post. You might want to double check your system and make sure your syntax is correct.

Thanks Roberts for your reply. /opt/eth0.sh is executable now.

I’ve backup this config using “filetool.sh –b” and rebooted the box. Unfortunately it doesn’t work.
Quick question, may I know how to use the boot code of nodhcp?

I’ve noticed something after reboot. There are two situations now:

1.   I’ll get DHCP ip if I did not login to root
2.   I’ll get static ip if I login to root immediately

Code: [Select]

sudo su

Hi Adam
Reread reply #6 and edit your  /opt/eth0.sh  accordingly. This is not high school, spelling counts.

well you need to do the following hack

just add following line in .xsession  in ~/tc ( it works for me ...)

sleep 5

sudo ifconfig eth0 xx.xx.xx.xx netmask xxx.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx.xxx up
sudo route add gw xx.xx.xx.xx
sudo echo 8.8.8.8 > /etc/resolv.conf
other  command if needed


( where "x" is  IP address you want to set  )

Am not sure but wouldn't you use ControlPanel > Network to set static IP addresses??

Title: Re: [SOLVED] How to set permanent ip address in Tiny Core Linux?
Post by: Lee on October 22, 2013, 01:42:19 PM

The control panel network applet essentially just does the three sudo commands similar to those given in reply #12.

Post by: tinypoodle on October 22, 2013, 05:58:10 PM

A command in .xsession would be executed on every start of X11.

Post by: gerald_clark on October 22, 2013, 06:09:22 PM

.xsession is the wrong place. It is for  X and only X.
Putting configuration scripts in the wrong place will only cause support issues later when you can't figure out why the
proper config script in /opt does not seem to work.

on every reboot, eth0 gets ip from dhcp server, if you set Static IP  from control-panel, it gates flushed on reboot. You have to manually set IP address after restart.

it works for me .... really ...I do not need to go to each thin-client to change the IP address to the static which I want to assign to that machine  , I've added that command to .xsession it works like anything,

Post by: coreplayer2 on October 23, 2013, 03:21:03 AM

Thanks Gerald, I got it now.. 

write a script to set static IP, place it in /opt  and start it from an entry in bootlocal.sh on each boot

No you don't, but you have to use boot code "nodhcp".

Have you tried to see what happens when you start X for the second time?
