Also I cannot run two instances of zcount. First instance:
*# zcount -i zc:eth0 -c 1* ========================= Absolute Stats: 290'517 pkts (0 drops) - 241'724'964 bytes ========================= ========================= Absolute Stats: 558'359 pkts (0 drops) - 461'319'923 bytes Actual Stats: 267'802.09 pps (0.00 drops) - 1.76 Gbps ========================= ========================= Absolute Stats: 842'118 pkts (0 drops) - 699'454'776 bytes Actual Stats: 283'714.45 pps (0.00 drops) - 1.90 Gbps ========================= ========================= Absolute Stats: 1'129'661 pkts (0 drops) - 942'027'493 bytes Actual Stats: 287'499.01 pps (0.00 drops) - 1.94 Gbps ========================= Second instance: *# zcount -i zc:eth0 -c 1* pfring_zc_create_cluster error [Invalid argument] Please check that pf_ring.ko is loaded and hugetlb fs is mounted But everything seems fine: *# lsmod | grep pf_ring* pf_ring 691861 1 *# cat /etc/mtab | grep huge* none /mnt/hugepages hugetlbfs rw 0 0 If I don't use ZC at all (-i eth0) I can get many instances of Snort working (in my case, 22 instances) and everything seems to work fine. Any help will be appreciated. Regards, Jose Vila.
