Hi Friends, I cannot find older threads which dealt with similar problem, if any thread exists I apologize. This is my problem. When I try to execute the command "ebtables -A FORWARD -p IPv4 --ip-src 172.16.1.4 -s ! 00:11:22:33:44:55 -j DROP" (I take this command from one of the example in ebtables website.) I am getting the following error message. Unable to update the kernel. Two possible causes:1. Multiple ebtables programs were executing simultaneously. The ebtables userspace tool doesn't by default support multiple ebtables programs running concurrently. The ebtables option --concurrent or a tool like flock can be used to support concurrent scripts that update the ebtables kernel tables.2. The kernel doesn't support a certain ebtables extension, consider recompiling your kernel or insmod the extension. Details on Platform: 1. I have cross compiled ebtables v2.0.10-2 by removing the codes parts which are corresponding to IPv6. (The target I am using does not support IPv6 features). The compilation was successful and I can see the ebtables executables. 2. I have the following modules available in the /lib/modules/net/bridge/netfilter directory of my target: ebt_802_3.ko ebt_dnat.ko ebt_mark.ko ebt_snat.ko ebtable_broute.koebt_among.ko ebt_ip.ko ebt_mark_m.ko ebt_stp.ko ebtable_filter.koebt_arp.ko ebt_limit.ko ebt_pkttype.ko ebt_ulog.ko ebtable_nat.koebt_arpreply.ko ebt_log.ko ebt_redirect.ko ebt_vlan.ko ebtables.ko 3. The ebtable kernel components are compiled as modules. 4. The filesystem of the platform is read only. The /var partition with some small size is readable although. 5. Before trying the execution of the command, I did insmod for all the modules listed above. Please assist me to get the issue resolved, I am a newbie to ebtables. Thanks in Advance CheersVENKATESWARAN Bug the Bugs -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
