| | | | | | | | | | | | | | Add support for using CIDR notation in --{orig,tuple}-{src,dst} arguments, instead of free-form formatting netmask in --mask-{src,dst}. Example: conntrack -L -s 2001:db8::/56 Instead of: conntrack -L -s 2001:db8:: --mask-src ffff:ffff:ffff:ff00:: Signed-off-by: Asbjørn Sloth Tønnesen <ast@fiberby.dk> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* conntrack: add zone direction supportDaniel Borkmann2015-09-291-1/+9
| | | | | | | | | | | | | | | | This patch adds support for zone directions. Since all options have the orig/reply as a prefix, I named it --orig-zone and --reply-zone to stay consistent with the rest of the cmdline options. As for the option chars, there was no unallocated reasonable combination, thus only long options are officially exposed in the help, similarly as in other cases. Test suite results, after patch: OK: 79 BAD: 0 Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* man: fix hyphen used as minus signArturo Borrero2014-09-251-11/+11
| | | | | | | | | | | | | | Report from Debian's lintian: This manual page seems to contain a hyphen where a minus sign was intended. By default, "-" chars are interpreted as hyphens (U+2010) by groff, not as minus signs (U+002D). Since options to programs use minus signs (U+002D), this means for example in UTF-8 locales that you cannot cut and paste options, nor search for them easily.

* conntrack: add support for mark maskFlorian Westphal2011-06-151-2/+6
| | | | | | | | | | | | | | | Extend --mark option to optionally take a mask, seperated by '/', e.g. --mark 0x80/0xf0. When used with -L, only test those bits of the mark that are in the mask range (behaves like iptables like -m mark). When used with -U, zero out those bits indicated by the mask and XOR the new mark into the result (behaves like iptables -j MARK --set-xmark).

| | | | | | | | | This patch adds `-S' command to display kernel statistics. Using raw `cat' on /proc and the hexadecimal output is not very handy. This option parses the /proc entry and display the information is a more human friendly way. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| | | | | | | | | | This patch adds the -C command, to display the table counter. In the case of `-C conntrack' the tool reads the proc interface. For expectation, it loops on the table to count the number of entries (as there is not proc interface to display the number of expectations). Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
