tcpdump loses lots of packets
...running a DNS server on it, for testing. As part of my testing, I'm attempting to capture all the DNS queries arriving on the server, using tcpdump. However, tcpdump's performance is abysmal, and it loses lots of the packets. Here's the output when I stop the capture: # tcpdump -nn -i p1p1 -w /dev/shm/queries.pcap -B 65536 dst host 193.0.14.129 tcpdump: listening on p1p1, link-type EN10MB (Ethernet), capture size 65535 bytes ^C4096558 packets captured 6882162 packets received by filter 2785604 packets dropped by kernel The number 6882162 is exactly the number of DNS queries I am se...

Mixed bonding and vlan on plain adapter possible?
...ng mode. My first tests were only with iSCSI in place to verify connection is ok I followed these Dell guidelines, for both multipath and sysctl configs for network adapters: http://en.community.dell.com/techcenter/extras/m/white_papers/20442422 iSCSI vlan is 100 so that the configured devices are p1p1.100 and p1p2.100 and my sysctl config is: net.ipv4.conf.p1p1/100.arp_announce=2 net.ipv4.conf.p1p2/100.arp_announce=2 net.ipv4.conf.p1p1/100.arp_ignore=1 net.ipv4.conf.p1p2/100.arp_ignore=1 # net.ipv4.conf.p1p1/100.rp_filter=2 net.ipv4.conf.p1p2/100.rp_filter=2 So far so good and my lun is viewed...

CentOS 6 : Network Interface Naming
Hello All, I have one CentOS 6 KVM virtualization server that I built around a year ago (best I can tell it was in October 2012) at which time I would have been installing 6.3 [0]. That particular install used the Consistent Network Device Naming [1] conventions (PCIe NICs are p1p1, p1p2). I started to build out a new KVM virt server (kickstarting a 6.4 install now as compared to 6.3 back then) and the interface names are back to the old ethX convention for the PCIe NICs. See below for my snippets from udev persistent rules on the two hosts. I'm working off of [older]...

tcpdump loses lots of packets

It seems like the qtx module is somehow interfering with the packet capture, but I...
