For this reason I disabled CONFIG_PROC_SYSCTL. I have figured out the hard way that this functionality implements the successful randomisation of source ports, it might be responsible for the initialisation of net.ipv4.ip_local_port_range. Effectively, booting a kernel with ip=dhcp works. Ping-pong (ICMP) to and from an address works. DNS queries (UDP/53) don't because the source port remains 0, a connection to a typical webserver also seems to result in a no reply situation. -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
