我怀疑我的卡已经处于 IT 模式，但我想在连接驱动器之前确定一下。似乎sas2flash无法在 Ubuntu 上安装（至少sudo apt install sas2flash不起作用。我确实尝试过这个命令：

这条线路Protocol=(Initiator,Target)听起来像是卡处于 IT 模式。有人能确认这是否是在没​​有启动到装有 sas2flash 的 USB 的情况下进行验证的正确方法吗？

我正在尝试明确设置我的 DNS 服务器，因为我想知道我的媒体服务器速度慢是否是由于糟糕的 Verizon DNS 造成的。但是我到处搜索，却找不到任何可行的方法。检查我的 DNS 时显示以下内容：

❯ resolvectl dns
Global: 1.1.1.1 1.0.0.1
Link 2 (eno2): 192.168.1.1

或者

❯ nmcli device show eno2 | grep IP4.DNS
IP4.DNS[1]:                             192.168.1.1

我的理解是我的 DNS 是通过 DHCP 设置的，但尝试使用它来更改resolvetl dns eno2 1.1.1.1它却无法持久，并且将其添加到也无法持久/etc/systemd/resolved.conf.d/dns_servers.conf：

[Resolve]
DNS=1.1.1.1 1.0.0.1

还尝试设置此文件/etc/systemd/network/eno2.network：

[Match]
Name=eno2

[DHCPv4]
UseHostname=no
UseDNS=no
UseNTP=no
UseDomains=no

[DHCPv6]
UseHostname=no
UseDNS=no
UseNTP=no

[Network]
DNS=1.1.1.1 1.0.0.1
Domains=cloudflare-dns.com

但那也不起作用。

我认为这是我的问题：

❯ cat /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

但是我不知道如何覆盖网络管理器。nmcli似乎什么也没做，或者也许我执行了错误的命令：

❯ nmcli con
NAME                UUID                                  TYPE      DEVICE

❯ nmcli device show eno2 | grep IP4.DNS
IP4.DNS[1]:                             192.168.1.1
❯ sudo nmcli con mod "Wired connection 1" IP4.DNS "1.1.1.1 1.0.0.1"
Error: invalid or not allowed setting 'IP4': 'IP4' not among [connection, 802-3-ethernet (ethernet), 802-1x, dcb, sriov, ethtool, match, ipv4, ipv6, hostname, tc, proxy].
❯ resolvectl dns
Global: 1.1.1.1 1.0.0.1
Link 2 (eno2): 192.168.1.1

我目前无法物理访问这台机器，因此无法使用 UI 设置 DNS，也没有为 RDP 打开端口。但肯定有某种方法可以仅通过 CLI 进行设置吧？

我想升级我的 openssh 版本以解决CVE-2024-6387问题，运行后apt update我apt upgrade看到以下输出：

❯ sudo apt upgrade openssh-client

openssh-client is already the newest version (1:8.9p1-3ubuntu0.10).

❯ ssh -V

因此，我的 openssh-client 和 openssh-server 都使用修补版本 8.9p1-3，但运行时ssh -V我看到的是 8.9p1，这似乎是未修补的版本。这是预期的行为吗？ssh -V还是它以某种方式指向了错误的版本？如果是这样，我该如何修复？
