explain strange behavior
by Dan Hyatt 19 Aug '16

19 Aug '16

In my bin directory, most of the binaries are linked to it. It is in my path. I have googled this and cannot find anything close. I am running bash on centos6.8 When I run "which command" most of the files in this custom bin directory show up. When I run "which file.jar" it cannot see it, but I can *ls* the file (soft link) as which only works on executables (according to man page), I created a dan.jar empty file and did a which on dan.tar and found it. can anyone explain what is happening and how I can soft link the jar files to my bin directory so which can see them? Dan

BUG: soft lockup - CPU#0 stuck for 36s! [swapper/0:0]
by correomm 18 Aug '16

This bug is reported only on the VM's with CentOS 7 running on on VMware ESXi 5.1. The vSphere performance graph shows high CPU consume and disk activity only on VM's with CentOS 7. Sometimes I can not connect remotely with ssh (timeout error). The details of last issues was reported to retrace.fedoraproject.org. ¿Do you have a hint?

I followed the instructions (I thought) for hfsplus on C7. Installed elrepo Then installed hfsplus hfsplus-tools and kmod-hfsplus kmod-hfs rpm -qa | grep hfs clearly shows the items kmod-hfsplus-0.0-2.el7.elrepo.x86_64 hfsplus-tools-540.1.linux3-4.el7.x86_64 kmod-hfs-0.0-2.el7.elrepo.x86_64 When I do my mount command mount -t hfsplus -o loop Mac.dmg /mnt/mac mount: unknown filesystem type hfsplus What did I miss? Thanks, Jerry

firewalld and just a routing between local lans
by lejeczek 16 Aug '16

16 Aug '16

hi how much different iptables are in 7 from 6 I'm just learning, I expected that since IFs belong to the same zone traffic between them would pass, be forwarded without any extra settings/configuration but, I'm wrong it turns out. Am I missing something and there actually is a simple way, designed to make that routing between lans/interfaces just work - a one liner, one option/setting in that comprehensive(?) firewalld configuration? How does firewall make your centos a router of directly connected LANs? many thanks L.

local routing puzzle
by lejeczek 16 Aug '16

hi everyone I'm having a bit of a puzzle on one centos system, I have four interfaces: nm-team1 10.5.6.100 em1 192.168.2.17 em2 192.168.2.18 p3p3 172.25.12.222 I do: ping 10.5.6.17 -I em1 PING 10.5.6.17 (10.5.6.17) from 192.168.2.17 em1: 56(84) bytes of data. 64 bytes from 10.5.6.17: icmp_seq=1 ttl=64 time=0.367 ms the same for -I em2, for -I em1 and naturally for -I nm-team1 - all good. but: $ ping 10.5.6.17 -I p3p3 PING 10.5.6.17 (10.5.6.17) from 172.25.12.202 p3p3: 56(84) bytes of data. and nothing, ping waits and no reply, Ctrl+C with such a simple setup rules based routing should not be involved, kernel should figure it out, right? many thanks.

tcpdump loses lots of packets
by Anand Buddhdev 16 Aug '16

16 Aug '16

Hi folks, I've got a Dell R320 running CentOS 7, and a 10G NIC. I'm 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 sending from another server (the source). The filter is seeing them. However, not all of them make it into the pcap file. First I was writing to the disk, and thought it might be a bottleneck, so I tried to write to /dev/shm. You'll see I've also increased the buffer size with -B, but none of this helps. The packet rate is also not that high. From the sending side, this is what I have: # tcpreplay -i qtx:p1p1 5min.pcap Actual: 6882162 packets (620533334 bytes) sent in 317.08 seconds. Rated: 1951900.0 Bps, 15.61 Mbps, 21648.97 pps Flows: 4254416 flows, 13382.96 fps, 6882162 flow packets, 0 non-flow This is a very modest rate. Any ideas why tcpdump loses so many packets? And how to make it do better? Regards, Anand
