@Buffer2Disk 嗯，是抓包实现的，可以做 DPI，如果只是需要网卡包统计的话确实用不到。
了解了下 vnstat 直接读的系统数据，应该可以和 ifconfig 的结果对比下就知道数据对不对了吧？

@SharkIng 具体有啥影响？最新 kernel 有做了修复，不过不知是否完全修复。

这个错误我是刚重启的时候连不上 SSH 进 hyper-v console 才发现的，重启 VM 后 SSH 正常但是还是报了 2 条 unregister_netdevice，不知是否相关。

[以下有点乱，仅作个人记录]
看了下 dmesg，还伴随着很多“ docker0: port #(veth......) entered blocking/disabled state ”的 log，看了下 GCE/Vultr KVM 的 VM 也有 blocking/disabled log （但是没有 unregister_netdevice ），猜测是 packetbeat 抓包导致的。（没有 packetbeat 抓包的机子就没有这些 log。）
PS1：所有 container 都是--net host 运行
PS2：报 unregister_netdevice 的 VM 用的是 B150 主板板载 Realtek 网卡...
PS3：目前 kernel 4.10.0-19-generic，准备升 4.11 看下

贴下 unregister_netdevice 那台机器的 dmesg，当作记录：

为啥选这个工具？看了下貌似是新项目？
推荐研究下 pmacct 或 Elastic stack 的 packetbeat，最近也正在研究

@mimicom 内部只有 3 节 5 号点焊的空间，18650 放不下；功率只有 1w，比 2 节版还小，动力锂应该用处不大。
准备改 14500 锂电*1+保护板或充电板，如果能找到 4.3v 高压版 14500 锂电+迷你升压板应该更完美了。

涨的太夸张的一般都要领神券买的，比如：

@Bairrfhoinn 买米要买支持 99-30 满减叠加 99-30 （糯米杂粮叠 99-50 ）的，加运费大米每袋也才 20 不到

你设置的可能不是 CMC IP，而是 IDRAC IP。通过 COM 口改 DHCP 前默认 192.168.0.120

http://www.dell.com/support/manuals/us/en/19/dell-cmc-v1.30-poweredge-fx2/CMCFX2FX2s13UG-v1/Checklist-to-set-up-chassis?guid=GUID-767EC114-FE22-477E-AD20-E3356DD53395&lang=en-us

The default CMC network configuration is Static with the CMC IP address 192.168.0.120. If you want to change the network configuration to DHCP, connect a serial cable to serial port on the CMC.

那个灯闪？确定是绿灯不是蓝灯？绿转黄 /橙可能电源问题，应该不太可能。

多年没碰刀片了，差不多忘光了，建议仅供参考。

拿掉路由器直连猫看下

把服务器网线换到其他设备试下能 ping ？搞不好路由器 /防火墙做了 IP 隔离啥的
日志提示什么？服务器报错的话应该可以找售后了

不过原包装密封的话应该除外：

对超出查验和试用需要而使用商品，导致商品产生明显的价值贬损，视为商品不完好

https://service.tmall.com/support/tmall/knowledge-1124463.htm

商品完好指商品能够保持原有品质、功能，包括商品本身、包装、配件及附带的商标吊牌、使用说明书等齐全。买家基于查验需要而打开商品包装，或者为确认商品的品质、功能而进行合理、适当的试用不影响商品的完好。

@burndown 哭晕在厕所，之前一直直接 docker push 没发现 auto build 的选项，以为免费账号的限制，刚再研究了下，原来 docker hub 要 Profile > Settings > Linked Accounts & Services 加上 Create > Create Automated Build （ https://docs.docker.com/docker-hub/builds/ ）才是 Automated Build 的 repo。。。。
