Trying to build a script which will do the following:
1.) Due to continued stalling after each reboot will consider the uptime of the server and if it is less than 30 sec to load the following settings on your network.
essentially
2.) What interests me primarily is to make a script which only runs to enter the following settings on your network.
shell comparisons do not work that way. Shell operations don't have a <= operator either, it's called "-le" for "less than or equal". Nor are you feeding the output of the uptime command into the comparison, you're just giving it the name of the command. And uptime doesn't report the system uptime in any manner the shell could sensibly compare it anyway, at least on my system.
My system has the file /proc/uptime which the system uptime can be read from in seconds. It has two decimal places, which will need to be removed for the shell to understand it as a number.
# We don't care about G, but if we only specify one variable here, it'll cram both numbers into one variable.
read A G < /proc/uptime
# Remove decimal point
A="${A/.*/}"
if [ "$A" -lt 30 ]
then
echo setup network card
ifconfig wlan0 192.168.1.101 netmask 255.255.255.0 up
route add default gw 192.168.1.1
iwconfig wlan0 essid linksys
iwconfig wlan0 key 123abcd123
fi
Also, you don't need semicolons at the end of a command unless you want to put more than one command on the same line.
Do you have static DNS servers set up in /etc/resolv.conf ?
