windows 作为 samba server

https://github.com/samba-team/samba

server 配置

创建目录 New-Item -Path “C:\Share” -ItemType Directory -Force

然后在图形界面中，右键配置共享

在 linux 中执行如下即可:

smbclient -L //10.0.0.8/ -U "martins3\97936"

如果可以看到如下的结果，那么说明是可以联通的:

Password for [MARTINS3\97936]:

        Sharename       Type      Comment
        ---------       ----      -------
        ADMIN$          Disk      远程管理
        C$              Disk      默认共享
        IPC$            IPC       远程 IPC
        Share           Disk

手动连接:

sudo mount -t cifs //10.0.0.8/Share mnt \
    -o username=97936,password=1@3456aB,domain=MARTINS3,vers=3.0,iocharset=utf8

client 配置

不要使用密码

sudo mkdir -p /etc/samba sudo vim /etc/samba/credentials_martins3

username=97936
password=你的实际密码
domain=MARTINS3

sudo chmod 600 /etc/samba/credentials_martins3 sudo chown root:root /etc/samba/credentials_martins3

sudo mount -t cifs //10.0.0.8/Share mnt
-o credentials=/etc/samba/credentials_martins3,vers=3.0,iocharset=utf8,uid=$(id -u),gid=$(id -g)

自动 mount

最后添加到 /etc/fstab 中如下内容:

//10.0.0.8/Share  /home/martins3/hack cifs  credentials=/etc/samba/credentials_martins3,vers=3.0,iocharset=utf8,uid=1000,gid=1000,file_mode=0755,dir_mode=0755,nofail  0  0

执行 sudo mount -a

基本观察

可以看看 linux 上的 Samba 的源码是哪里的

  ├─samba-smbd.service
  │ ├─  4169 /nix/store/mcyfbsbxr2hjr53v2yyvqnsnlg894xk2-samba-4.20.1/sbin/smbd
  │ ├─  4229 smbd: notifyd
  │ ├─  4231 smbd: cleanupd
  │ └─760872 smbd: client [10.0.0.8]

性能测试

[global]
time_based=1
runtime=1000
ioengine=io_uring
iodepth=1024
numjobs=2
bs=4k

[trash]
rw=randread
filename=/home/martins3/mnt/a.dump
size=10G

trash: (g=0): rw=randread, bs=(R) 4096B-4096B, (W) 4096B-4096B, (T) 4096B-4096B, ioengine=io_uring, iodepth=1024
...
fio-3.39

q^Cs: 2 (f=2): [r(2)][28.7%][r=84.1MiB/s][r=21.5k IOPS][eta 11m:54s]

考虑到网络只有 1Gb ，所以其实还是还不错的。

问题

在映射的目录中，linux 无法构建软连接

ln: failed to create symbolic link '/home/martins3/hack/vm/fedora/iso': Operation not permitted

在映射的目录中，linux 无法构建unix domain socket

这些报错都是完全看不懂的

🧀   nc -l -U a.sock
nc: Permission denied

 sudo nc -l -U a.sock
[sudo] password for martins3:
Ncat: bind to a.sock: Permission denied. QUITTING.

有时候遇到这个错误

如果 linux 虚拟机和 client 断开之后，那么就会遇到这个错误
