Hello, I have some routers running OpenWRT (latest nightly) and that I have to access remotely (using reverse SSH). When I restart networking (/etc/init.d/network restart), clients on the LAN can no longer obtain an IP address using DHCP. If I restart networking locally, DHCP works as expected after the network is back up.
In order to try and figure out what is going on, I have checked/tried the following: * I started out by checking if dnsmasq has been restarted and if the DHCP socket has been created. I can always see the socket in netstat. * I then took a look at the firewall. I can see the DHCP packets in the INPUT chain in filter, which according to my understanding of Netfilter-internals is the last stop before a packet is delivered to a socket. * I then instrumented dnsmasq and added some logging in dhcp_packet() in dhcp.c. This function is never called, as none of my log-messages are written to syslog. I checked that the logging works by checking for my messages when DHCP is working. * Restarting dnsmasq makes DHCP work again. I can't see any difference in for example netstat-output. Does anyone have any idea on what to try or where to look next? After having spent a couple of days on this issue, I am quickly starting to run out of ideas. Thanks in advance for any help, Kristian _______________________________________________ Dnsmasq-discuss mailing list Dnsmasqemail@example.com http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
