SSH to change IP

[frosezz]

I am sshing from a windows box to fedora. I am attempting to write a batch file in windows that will ask a few questions assign the variables etc etc. The issue is when I am trying to change the ip address of a linux machine, permanently. The ips have to be static and can change every so often. So I can ssh into fedora no issues and I can use ifconfig to change temporarily, till restart. The script should be automated so use clicks it asks a few questions then poof ip is changed for good. I am at a loss of how to do this. I am reletively new at this.

Is there a way to do it this way? or do I need to have a script in fedora that this file connects to and runs? can you pass variables this way? I hate to ask this but if that is the case how would you write it. thanks and i am sorry if this is not structured very well in thought.

instead of using ifconfig, simply edit the config file for the device, it will be in /etc/sysconfig/network-scripts and it will be called something like ifcfg-eth0, but that will depend on the device, you need to be root or have sudo privilege to change this file, then you can restart network with /sbin/service network restart (also requires root/sudo)

yea i know how to do this. but this script will go to an end user that doesnt. they need to be on a windows box click the go button it ask them a few questions then the script needs to do all the work. thanks though.

Would the code below work on Fedora as a shell script?


#!/bin/sh

#setting up variables
ip=$1
mask=$2
gate=$3
export ip
export mask
export gate

#Modifying the ifcfg-eth0 file
awk -v ip=$ip -v mask=$mask -v gate=$gate '/ONBOOT=yes/{
print
print "DEVICE=eth0"
print "BOOTPROTO=static"
print "IPADDR=" ip
print "NETMASK=" mask
print "GATEWAY=" gate
next cd
}1' /etc/sysconfig/network-scripts/ifcfg-eth0> /etc/sysconfig/network-scripts/temp1

sed -e's/no/yes/' /etc/sysconfig/network-scripts/temp1 > /etc/sysconfig/network-scripts/temp2

rm /etc/sysconfig/network-scripts/ifcfg-eth0
mv /etc/sysconfig/network-scripts/temp2 ifcfg-eth0
chmod 644 /etc/sysconfig/network-scripts/ifcfg-eth0
rm /etc/sysconfig/network-scripts/temp1
rm /etc/sysconfig/network-scripts/temp2
