装的是ubuntu-mate，和windows通过samba传输文件，自适应网卡没法用100M，总是自动用10M，请问该怎么办？
网卡是NVIDIA的板载网卡，谢谢

Ethernet Interface Settings
sudo apt-get install ethtool
pre-up /sbin/ethtool -s eth0 speed 1000 duplex full
1-1. 上面的 1000 是 1000 Mb/s
1-2. http://manpages.ubuntu.com/manpages/tru ... ool.8.html
ethtool - query or control network driver and hardware settings

如果還有疑問 請提供你的 ubuntu 版本

把结果全部复制贴上来

闪了一下就直接返回了，没有任何结果

或者详细说明你的硬件型号 规格

sudo ethtool -s enp0s7 speed 1000 duplex full
Cannot set new settings: Invalid argument
not setting speed
not setting duplex

最新版的 ubuntu-mate

我不知道什么命令看型号规格，以前windows直接可以看到，换了linux就看不了

把结果全部复制贴上来

samba 传输数据的最大速度是多少？

samba 传输数据最大是1M/s

1. pre-up /sbin/ethtool -s eth0 speed 1000 duplex full
不是下指令
而是寫在連線設定檔裏
啟動連線時 就生效
2. 連線設定檔 /etc/network/interfaces
3. sudo ifconfig -a
確定 你的有線網卡界面是 enp0s7
4. 1000 M 需要你的網卡/路由支援
如果不支援 試試 100 M


5. 版本 指 14.04 15.10 ...

6. 你這裡已是 100M

1.per-up: command not found
per-up 是什么意思呢？
2.要修改interfaces吗？
3.确定是enp0s7了
4.我的是10/100m，所以我只要100M，现在是自动选择10M

从这里看 协商的速度等于 100000000 == 100M
samba 速度慢可能另有原因

1. 是 pre-up

2. http://manpages.ubuntu.com/manpages/sau ... ces.5.html
pre-up command
Run command before bringing the interface up. If this command
fails then ifup aborts, refraining from marking the interface as
configured, prints an error message, and exits with status 0.
This behavior may change in the future.
在網卡界面啟動前 先執行 /sbin/ethtool 設定連線速度

3. 對

4. 如果你使用
pre-up /sbin/ethtool -s enp0s7 speed 100 duplex full
如上 2 所述 只有 100 M 可以連線
否則 網卡啟動失敗 並且出現失敗訊息通知你
4-1. 實測傳輸速度
還要看其他網路相關環境的硬件/驅動/程式 而定

好的，谢谢大家
