Hi, I just updated to linux kernel 2.1.22 and when trying to use iptables, I get the following answer: # iptables -L iptables v1.3.8: can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. I read on other forums that it could come from the /boot/config file. And it should be true, when I compare my file to old ones I see that lot of things aren't configured. Let's look at its Networking part: ============================================# # Networking # CONFIG_NET=y # # Networking options # CONFIG_PACKET=y # CONFIG_PACKET_MMAP is not set CONFIG_UNIX=y # CONFIG_NET_KEY is not set CONFIG_INET=y CONFIG_IP_MULTICAST=y # # added by seb on 08/13/07 # enables conntrack #CONFIG_NF_CONNTRACK_ENABLED=m # CONFIG_NF_CONNTRACK=m CONFIG_NF_CONNTRACK_IPV4=m # CONFIG_IP_ADVANCED_ROUTER is not set CONFIG_IP_FIB_HASH=y CONFIG_IP_PNP=y CONFIG_IP_PNP_DHCP=y # CONFIG_IP_PNP_BOOTP is not set # CONFIG_IP_PNP_RARP is not set # CONFIG_NET_IPIP is not set # CONFIG_NET_IPGRE is not set # CONFIG_IP_MROUTE is not set # CONFIG_ARPD is not set # CONFIG_SYN_COOKIES is not set # CONFIG_INET_AH is not set # CONFIG_INET_ESP is not set # CONFIG_INET_IPCOMP is not set # CONFIG_INET_XFRM_TUNNEL is not set CONFIG_INET_TUNNEL=y # CONFIG_INET_XFRM_MODE_TRANSPORT is not set # CONFIG_INET_XFRM_MODE_TUNNEL is not set # CONFIG_INET_XFRM_MODE_BEET is not set CONFIG_INET_DIAG=y CONFIG_INET_TCP_DIAG=y # CONFIG_TCP_CONG_ADVANCED is not set CONFIG_TCP_CONG_CUBIC=y CONFIG_DEFAULT_TCP_CONG="cubic" # CONFIG_TCP_MD5SIG is not set CONFIG_IPV6=y # CONFIG_IPV6_PRIVACY is not set # CONFIG_IPV6_ROUTER_PREF is not set # CONFIG_IPV6_OPTIMISTIC_DAD is not set # CONFIG_INET6_AH is not set # CONFIG_INET6_ESP is not set # CONFIG_INET6_IPCOMP is not set # CONFIG_IPV6_MIP6 is not set # CONFIG_INET6_XFRM_TUNNEL is not set # CONFIG_INET6_TUNNEL is not set # CONFIG_INET6_XFRM_MODE_TRANSPORT is not set # CONFIG_INET6_XFRM_MODE_TUNNEL is not set # CONFIG_INET6_XFRM_MODE_BEET is not set # CONFIG_INET6_XFRM_MODE_ROUTEOPTIMIZATION is not set CONFIG_IPV6_SIT=y # CONFIG_IPV6_TUNNEL is not set # CONFIG_IPV6_MULTIPLE_TABLES is not set # CONFIG_NETWORK_SECMARK is not set # # CONFIG_NETFILTER is not set # netfilter configuration by seb: # CONFIG_NETFILTER_NETLINK=m CONFIG_NF_CT_NETLINK=m CONFIG_NF_CONNTRACK_EVENTS=y # CONFIG_IP_DCCP is not set # CONFIG_IP_SCTP is not set # CONFIG_TIPC is not set # CONFIG_ATM is not set # CONFIG_BRIDGE is not set # CONFIG_VLAN_8021Q is not set # CONFIG_DECNET is not set # CONFIG_LLC2 is not set # CONFIG_IPX is not set # CONFIG_ATALK is not set # CONFIG_X25 is not set # CONFIG_LAPB is not set # CONFIG_ECONET is not set # CONFIG_WAN_ROUTER is not set # # QoS and/or fair queueing # # CONFIG_NET_SCHED is not set # # Network testing # # CONFIG_NET_PKTGEN is not set # CONFIG_NET_TCPPROBE is not set # CONFIG_HAMRADIO is not set # CONFIG_IRDA is not set # CONFIG_BT is not set # CONFIG_AF_RXRPC is not set ================================================= hope you can help me, thanks Sebastien. _________________________________________________________________ With Windows Live Hotmail, you can personalize your inbox with your favorite color. www.windowslive-hotmail.com/learnmore/personalize.html?locale=en-us&ocid=TXT_TAGLM_HMWL_reten_addcolor_0607
