hi zusammen,

ich habe gerade ein reconnect script für den Dir-615 rev: D3 mit dd-wrt v24 und einem Kabel Modem von cisco gebastelt.

Was mir jedoch nicht gelungen ist, dass die MAC-Adresse von vlan2 einen Reboot des Routers überlebt.Diese wird jeweils auf einen default Wert zurückgesetzt.
/edit: die nvram variable def_hwaddr überlebt den reconnect kann diese direkt wieder benutzt werden?
Kann mir jemand sagen, wo die default startup config von dem vlan2 interface definiert ist?
Generell wenn jemand Verbesserungsvorschläge hat nur her damit.
Das größte Problem ist wohl, dass man keine Optware auf dem Router installieren kann. Somit muss das Modem via curl von Windows neu gestartet werden.

grüßle psy

1.) Batch für Windows
curl.exe und WinSCP in neuerer version vorrausgesetzt
Code:

@echo off
curl -d "SADownStartingFrequency=1" http://192.168.100.1/goform/gscan
c:\Programme\WinSCP3\WinSCP.com /script=c:\Programme\WinSCP3\script.txt

1.1) WinSCP-script
Code:

open scp://root:PASSWORT@192.168.0.1:22
call /tmp/etc/reconn.sh
close
exit

2.) Startupscript für dd-wrt firmware
Code:

echo "#!/bin/sh" >> /tmp/etc/reconn.sh
echo "MAC=\`(date; cat /proc/interrupts) | md5sum | sed -r 's/^(.{10}).*$/\1/; s/([0-9a-f]{2})/\1:/g; s/:$//;'\`" >> /tmp/etc/reconn.sh
echo "echo "00:\$\{MAC\}"" >> /tmp/etc/reconn.sh
echo "ifconfig vlan2 down" >> /tmp/etc/reconn.sh
echo "ifconfig vlan2 hw ether "00:\$\{MAC\}"" >> /tmp/etc/reconn.sh
echo "ifconfig vlan2 up" >> /tmp/etc/reconn.sh
echo "nvram set wan_hwaddr="00:\$\{MAC\}"" >> /tmp/etc/reconn.sh
echo "kill -USR2 \`cat /var/run/udhcpc.pid\` 2> /dev/null" >> /tmp/etc/reconn.sh
echo "killall udhcpc 2> /dev/null" >> /tmp/etc/reconn.sh
echo "udhcpc -i vlan2 -p /var/run/udhcpc.pid -s /tmp/udhcpc" >> /tmp/etc/reconn.sh
chmod +x /tmp/etc/reconn.sh

kill -USR2 \`cat /var/run/udhcpc.pid\` 2> /dev/null

udhcpc -i vlan2 -p /var/run/udhcpc.pid -s /tmp/udhcpc" > /tmp/etc/reconn.sh
chmod +x /tmp/etc/reconn.sh


und dannpack das ins startup or custom script
