Ok, that seems to solve it. Stupid me was trying ifdown eth0.2
Somehow I quickly read radio0.network1 and I confused it with "wlan"
instead of "wan" ... (O//o) :shame:
Many Thanks !
PS:
Here is the script for the interested. If someone wants to improve this
gibberish feel free!
#!/bin/sh
oldip==`ifconfig br-wan | sed -n -e 's/.*inet addr:\([0-9]*\.[0-9]*
\.[0-9]*\.[0-9]*\)\ .*/\1/p'`
echo "Old ip was $oldip"
oldsubnet=`ifconfig br-wan | sed -n -e 's/.*inet addr:\([0-9]*\.[0-9]*
\)\..*/\1/p'`
echo "Old subnet is $oldsubnet"
number=$(awk 'BEGIN{srand(); print int(255 * rand()) }')
sleep 1
number2=$(awk 'BEGIN{srand(); print int(255 * rand()) }')
pid=`pidof udhcpc`; /bin/kill -SIGUSR2 $pid
udhcpc -r "$oldsubnet.$number.$number2" -i br-wan
newip==`ifconfig br-wan | sed -n -e 's/.*inet addr:\([0-9]*\.[0-9]*
\.[0-9]*\.[0-9]*\)\ .*/\1/p'`
echo "New ip was $newip"
ifup wan
exit
If you do not want to store it in your config you can obviously call it
like
#!/bin/bash
ssh 192.168.1.1 -l root 'sh -s' < /home/martin/bin/open-wrt/script.bash
exit
and use a password-less key for automation
