Please help me to understand, service ulogd start; tailf /var/log/ulogd/ulogd.log Starting ulogd: [ OK ] Sun Apr 30 22:49:51 2017 <5> ulogd.c:940 building new pluginstance stack: 'ct2:NFCT,ip2str1:IP2STR,json1:JSON' Sun Apr 30 22:49:51 2017 <8> ulogd_inpflow_NFCT.c:1293 error opening ctnetlink Sun Apr 30 22:49:51 2017 <7> ulogd.c:910 error starting `ct2' Sun Apr 30 22:49:51 2017 <8> ulogd.c:1543 not even a single working plugin stack ^C [root@darshan-2 ulogd]# ulogd -d [root@darshan-2 ulogd]# tailf /var/log/ulogd/ulogd.log Sun Apr 30 22:48:16 2017 <5> ulogd.c:940 building new pluginstance stack: 'ct2:NFCT,ip2str1:IP2STR,json1:JSON' Sun Apr 30 22:48:16 2017 <8> ulogd_inpflow_NFCT.c:1293 error opening ctnetlink Sun Apr 30 22:48:16 2017 <7> ulogd.c:910 error starting `ct2' Sun Apr 30 22:48:16 2017 <8> ulogd.c:1543 not even a single working plugin stack Sun Apr 30 22:49:51 2017 <5> ulogd.c:940 building new pluginstance stack: 'ct2:NFCT,ip2str1:IP2STR,json1:JSON' Sun Apr 30 22:49:51 2017 <8> ulogd_inpflow_NFCT.c:1293 error opening ctnetlink Sun Apr 30 22:49:51 2017 <7> ulogd.c:910 error starting `ct2' Sun Apr 30 22:49:51 2017 <8> ulogd.c:1543 not even a single working plugin stack Sun Apr 30 22:51:40 2017 <5> ulogd.c:940 building new pluginstance stack: 'ct2:NFCT,ip2str1:IP2STR,json1:JSON' Sun Apr 30 22:51:40 2017 <5> ulogd_inpflow_NFCT.c:1399 NFCT plugin working in event mode Thanks, Darshan Ghumare -- 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
