使用scp / rsync后Manjaro / Arch Linux中无响应的ssh会话

Question

我在笔记本电脑上重新安装了Manjaro 20.2。现在，我尝试通过scp / rsync在本地网络和外部服务器(我相信是Ubuntu20.04)和另一台笔记本(kubuntu18.04)之间传输文件。

在这两种情况下，在我的Manjaro笔记本电脑上对rsync的初始调用将传输一些文件，然后暂停，最后中止：

laptop% rsync -rtvvvuL --progress user@webserver:/directory/ /home/user/directory/
[snip]
Timeout, server webserver not responding.
rsync: connection unexpectedly closed (112760 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(228) [receiver=v3.2.3]
[receiver] _exit_cleanup(code=12, file=io.c, line=228): about to call exit(12)
rsync: connection unexpectedly closed (100412 bytes received so far) [generator]
rsync error: unexplained error (code 255) at io.c(228) [generator=v3.2.3]
[generator] _exit_cleanup(code=12, file=io.c, line=228): about to call exit(255)
rsync: [generator] write error: Broken pipe (32)

如果在我的kubuntu笔记本上调用rsync与Manjaro同步文件，也会发生这种情况，所以Manjaro机器是服务器还是客户端并不重要。

如果在此之后，我再次尝试通过SSH连接到get服务器，则成功验证了我的身份，但没有得到命令提示符：

laptop% ssh -vvv user@webserver

而且，如果我再次调用rsync，它将什么也不做：

laptop% rsync -rtvvvuL --progress user@webserver:/directory/ /home/user/directory/
opening connection using: ssh -l user webserver rsync --server --sender -vvvuLtre.iLsfxCIvu . /directory/  (10 args)

在我的kubuntu机器上，我可以在没有问题的情况下与服务器进行ssh/scp/rsync。而且，从我的Android到我的kubuntu机器的连接是没有问题的，但是在Manjaro上它是挂起的。我在三个不同的妻子身上观察到了这个问题，这让我觉得这与网络无关。

ssh/sshd配置(或Manjaro机器上的任何配置)无关紧要，因为我可以使用Manjaro20.2 KDE系统再现问题。

Answer 1

我找到了解决办法。造成SSH问题的原因是我的wifi芯片组的驱动程序。我正在使用Broadcom BCM4311并安装broadcom-w驱动程序，解决了我的问题.我首先为所有已安装的内核安装了linux头包，然后安装了驱动程序。

sudo pacman -Syyu
sudo pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')
sudo pacman -S broadcom-wl-dkms

在重新启动之后，应该启用“w”驱动程序，我可以用以下命令确认这一点：

laptop% inxi -Fxz | grep BCM4331
           Device-2: Broadcom BCM4331 802.11a/b/g/n vendor: Apple AirPort Extreme driver: wl v: kernel port: efa0 

驱动程序应该是wl，而不是 bcma-pci-bridge。

以下网站为我指出了解决方案：

Answer 2

我在2013年macbook视网膜显示器(manjaro i3版)上挂着ssh也有类似的问题。我遵循了你提到的命令：

sudo pacman -Syyu
sudo pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')
sudo pacman -S broadcom-wl-dkms

我的无线网络也停止工作了。运行sudo pacman -S broadcom-wl修复了我用前面的命令中断的wifi。

对我起作用的是安装Linux510头(linux510- headers )，它与我使用sudo pacman -Syyu更新系统后的内核版本(Linux5.10.42-1)相匹配。
