我在我的 ubuntu vm 中安装了 opensearch 和 opensearch-dashboard。当我尝试使用以下命令找出 opensearch-dashboard 使用的资源时

top -U opensearch

我刚刚得到

Tasks: 125 total,   1 running, 124 sleeping,   0 stopped,   0 zombie
%Cpu(s):  0,2 us,  0,1 sy,  0,0 ni, 99,6 id,  0,0 wa,  0,1 hi,  0,1 si,  0,0 st

我认为这种信息聚合了 opensearch 和 opensearch-dashboard，我怎样才能找出仪表板使用的内存、CPU 和磁盘空间？

我继承了一个 ubuntu 8.10 服务器，它当前作为 samba 服务器和 apache web 服务器运行。我想用 ubuntu 19.10 制作一个新服务器并复制该服务器上的现有配置。我通常从头开始，我从未将 samba 配置为与活动目录集成。smb.conf 中的这个配置就够了吗？

# Global parameters
[global]
        workgroup = domain
        realm = domain.com
        server string = %h NEWSAMBASERVER (Samba %v)
        security = ADS
        password server = domaincontroller.domain.com
        #security = DOMAIN
        passwd program = /usr/bin/passwd %u
        passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n .
        username map = /etc/samba/smbusers
        syslog = 0
        max log size = 1000
        name resolve order = wins host bcast
        socket options = IPTOS_LOWDELAY TCP_NODELAY SO_SNDBUF=4096 SO_RCVBUF=4096
        load printers = No
        preferred master = No
        local master = No
        domain master = No
        wins support = Yes
        invalid users = root
        hosts allow = 10.100., 127.
#       printing = lprng
#       lppause command = lpc hold '%p' %j
#       lpresume command = lpc release '%p' %j

我想使用 netplan 更改 ubuntu 19.04 的网络掩码。我编辑了唯一的 yaml 文件，即 \etc\netplan\50-cloud-init.yaml

network:
    ethernets:
        ens160:
            addresses: [10.100.0.78/24]
            gateway4: 10.100.0.253
            dhcp4: no
            nameservers:
                addresses: [10.100.0.8,10.100.0.9]
            optional: true
    version: 2

但如果我给命令 ip a

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: ens160: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:50:56:bc:ff:52 brd ff:ff:ff:ff:ff:ff
    inet 10.100.0.78/24 brd 10.100.0.255 scope global ens160
       valid_lft forever preferred_lft forever
    inet6 fe80::250:56ff:febc:ff52/64 scope link
       valid_lft forever preferred_lft forever

我希望网络掩码为 255.255.0.0 。网络掩码设置在哪里？

我有一个带有ubuntu 17.10的hp pavilion笔记本，当我使用windows时，我可以运行死岛。在同一台机器上的 linux 下，游戏在第一个等待屏幕时崩溃。例如，如果我使用启动选项 -nologos -safemode 运行游戏，我会得到 Palm 屏幕、带有等待消息的黑屏，然后游戏就崩溃了。我还注意到游戏没有生成任何配置文件，因为文件夹设置：/DI/out/Settings/ 不存在。我仔细检查了游戏文件的完整性。我还可以提供 crash.log 文件（非常长的日志文件），因为我自己无法解决问题。

要解决我在 dota 2 中遇到的 glx 问题，我必须 sudo apt-get install libtxc-dxtn-s2tc0 dota 2 工作正常，死岛不是。

我有以下有趣的实验。我使用live usb在插入intel ss4200-e的usb上安装ubuntu server 12.04 i386和webmin，我想用它制作一个无头samba服务器。webmin 在分区菜单上显示以下情况：

Disk name       Total size      Make and model      Partitions      Actions   
SCSI device A   7.39 GB     Kingston DataTraveler 3.0   3   Identify drive

SATA device E   953.83 GB   ATA Hitachi HDE72101    1   IDE parameters | Identify drive

突袭菜单显示：

/dev/md0    clean   RAID5 (Distributed Parity)  2.60 TB     /dev/sdb1 | /dev/sdc1 | /dev/sdd1 | /dev/sde1

然后 \dev\md0 选项卡显示

fstab 看起来像这样：

# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a

例如，如何在启动时将该 /dev/md0 挂载到 /mnt/raidarray 中？

在 lubuntu 16.04 xenial 机器上，我想安装 quake2，更多的是用于测试。然后我想安装一个 quake 2 服务器，但首先要做的事情是：我已经从我的 windows 分区复制到我的 lubuntu 桌面，来自 windows 安装的旧 quake 2 游戏文件夹。所以在桌面上我有一个 Quake2 文件夹，里面有：baseq2、rogue、xatrix 子文件夹。我已经用 apt 安装了 quake2 二进制文件： apt-get install quake2

我想要做的是弄清楚如何让游戏包管理器为完整的 quake2 (baseq2)、reckoning (rogue)、ground zero (xatrix) 制作相关的 deb 文件。

有没有人成功完成它，或者有没有人知道它的语法？

我正在使用 Ubuntu 14.04。当我在 nautilus 中打开特定 DVD 时，出现此错误。

你能帮我找出问题吗？

我设法在 hp pavillion 笔记本上安装了 ubuntu 并对其进行了双重引导。为此，我必须在按下电源后立即按 esc 和 f10，才能访问 bios。在 bios 的引导选项中启用 legacy。然后我很好地安装并配置了 linux（debian ubuntu 和 arch linux）。只要我保留启用传统选项，我就会在启动后得到 grub。我想要实现的是，如果我在 BIOS 中禁用旧版支持，笔记本会提示我使用 grub2。现在，如果我禁用旧版，笔记本电脑将启动 Windows 10 并忽略 grub2。我认为这与 efi 有关，但我有限的知识仅限于此。

我正在使用 ubuntu、lubuntu、kubuntu：

Linux sysop 3.19.0-33-generic #38-Ubuntu SMP Fri Nov 6 18:18:12 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

在具有 Nvidia Ion 卡的 Asus Eee PC Seashell 系列 1215n 上。安装以下软件包后：

sudo apt-get install nvidia-346 nvidia-settings nvidia-prime

lightdm gdm sddm 无法启动。如果我想获得图形环境，我必须：登录 tty，然后执行以下操作：

sudo nvidia-xconfig
startx

有人可以帮我让桌面管理器工作吗？

在常规 Ubuntu 15.04 安装中安装 Lubuntu-Desktop 之后，我现在拥有了在登录后自动启动的 Libreoffice-Writer。我记得我在从 Ubuntu 13.04 升级后在 Ubuntu 14.04 中发现了同样的问题，但我不记得如何解决这个问题。什么会导致 libreoffice-writer 在登录后自动打开？有人能帮忙吗？
