Hi,
few weeks agoe I had sometimes the problem that batmand (experimental) exits silently. Today I found maybe one reason for this. When you have batman running and insert the iptable rule
iptables -I OUTPUT -o eth1 -j DROP
batmand exits. This also happen for additional interfaces controlled by batmand.
actually this is logged to syslog and debug level 4. A "logread -f" on OpenWRT systems should show something like that:
Error - can't send udp packet: Permission denied. Does your firewall allow outgoing packets on port 4306 ?
