* doc: fix typo SocketBufferSizeMaxGrowth in example conffilesPablo Neira Ayuso2008-12-173-3/+3
| | | | | | | | This patch replaces SocketBufferSizeMaxGrown by SocketBufferSizeMaxGrowth. Both clauses are still valid but better to use the one that has no typos in the configuration files. Signed-off-by: Pablo Neira Ayuso <>
* config: move `Checksum' inside `Multicast' clausePablo Neira Ayuso2008-11-303-18/+21
| | | | | | | | | This patch moves `Checksum' into the `Multicast' clause. This property is dependent of the multicast configuration. This patch is required to introduce the redundant dedicated link support that is on the way. Signed-off-by: Pablo Neira Ayuso <>
* filter: CIDR-based filtering supportPablo Neira Ayuso2008-11-253-0/+9
| | | | | | | | | | This patch adds CIDR-based filtering support. The current implementation is O(n). This patch also introduces the vector data type which is used to store the IP address and the network mask. Signed-off-by: Pablo Neira Ayuso <>
* filter: choose the filtering method via configuration filePablo Neira Ayuso2008-11-183-6/+30
| | | | | | | | | | | | | | | | This patch changes the current behaviour of the filtering selection. Up to now, conntrackd has used the kernel version to select the filtering method based on the following logic: If kernel is >= 2.6.26 we use BSF-based filtering from kernel-space, otherwise, default to userspace. However, this filtering method still lacks of IPv6 support and it requires a patch that got into 2.6.29 to filter IPv6 addresses from kernel-space. To fix this issue, we default to user-space filtering and let the user choose the method via the configuration file. Signed-off-by: Pablo Neira Ayuso <>
* ftfw: rise the size of the acknowledgment window in the examplePablo Neira Ayuso2008-10-211-2/+11
| | | | | | | | | This patch increases the size of the acknowledgment window based on some experiments in my testbed with oprofile. The previous default value was too small. This resulted in too many cycles to empty the resend queue. Signed-off-by: Pablo Neira Ayuso <>
* doc: remove example about CacheWriteTroughPablo Neira Ayuso2008-10-213-27/+0
| | | | | | | | | | | | | | | This patch removes the documentation about the CacheWriteTrhough clause. This feature is scheduled for removal since the asynchronous nature of conntrackd does not allow multi-path routing support. I'm lying, actually there's a chance to support it, but we have to guarantee that the RTT in the message synchronization between the firewall is smaller than the RTT between the peer and the firewalls. Moreover, this option has made more bad than good since people enable it when things don't work. Making the whole troubleshooting more complicated. Signed-off-by: Pablo Neira Ayuso <>
* doc: rise default size of the hashtable in the example filePablo Neira Ayuso2008-10-203-6/+6
| | | | | | | This patch rises the default value of the hashtables in terms of buckets and entries to the default value in nf_conntrack. Signed-off-by: Pablo Neira Ayuso <>
* manual: add initial user manualPablo Neira Ayuso2008-10-134-0/+634
| | | | | | This patch adds the manual in docbook format to the conntrack-tools. Signed-off-by: Pablo Neira Ayuso <>
* config: use /var/run to create the UNIX socket filePablo Neira Ayuso2008-09-184-4/+4
| | | | | | | | This patch removes the use of /tmp to create the UNIX socket file to communicate with conntrackd in the example configuration files. This was OK in the early alpha days, but not anymore. Signed-off-by: Pablo Neira Ayuso <>
* cache iterators: rework cache_reset_timersPablo Neira Ayuso2008-08-075-1/+45
| | | | | | | | | | | This patch adds the clause PurgeTimeout that sets the new timer when conntrackd -t is called. This command is particularly useful when the sysadmin triggers hand-overs between several nodes without rebooting as it reduces the timers of the remaining entries in the kernel. Thus, avoiding clashes between new and old entries that may trigger INVALID packets. Signed-off-by: Pablo Neira Ayuso <>

* script: rework scripts that enable interaction with keepalivedPablo Neira Ayuso2008-08-0210-104/+100
| | | | | | | | | | | This patch reworks the documentation section. It removes the replicated keepalived.conf files and merge all the scripts into one to reduce confusion and improve maintainability. It's likely that the documentation directory will suffer more restructurations in the near future. Signed-off-by: Pablo Neira Ayuso <>
* doc: remove duplicated example filesPablo Neira Ayuso2008-08-0112-632/+108
| | | | | | | | This patch removes the directories node1/ and node2/ since the differences are few small and the user should be able to get it running if he RTFM. Signed-off-by: Pablo Neira Ayuso <>
* fix: wrong information related to default logging actionPablo Neira Ayuso2008-08-017-21/+21
| | | | | | Logging is set off by default instead of what the example files state. Signed-off-by: Pablo Neira Ayuso <>

* Major rework of the user-space event filteringPablo Neira Ayuso2008-07-227-165/+279
| | | | | | | | | | This patch reworks the user-space filtering. Although we have kernel-space filtering since Linux kernel >= 2.6.26, we keep userspace filtering to ensure backward compatibility. Moreover, this patch prepares the implementation of the kernel-space filtering via libnetfilter_conntrack's high-level berkeley socket filter API. Signed-off-by: Pablo Neira Ayuso <>
