Those *mem* sysctl values under net/core/ aren't going to modify TCP behavior at all. You need to change the ones named net/ipv4/tcp_*mem. They are documented in the file named "Documentation/net/ip-sysctl.txt" in the kernel sources and probably elsewhere. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
