systemctl disable daytime-udp

这个命令用于禁用 "daytime-udp" 服务的自动启动。

具体而言，systemctl命令用于管理系统服务。通过执行 "systemctl disable daytime-udp" 命令，你可以禁用 "daytime-udp" 服务的自动启动，这意味着该服务将不会在系统启动时自动运行。

请确保你有足够的权限来执行此命令，并且确认 "daytime-udp" 服务存在并且可被管理。注意，禁用某些服务可能会影响系统功能，所以在执行此命令之前，请确保你了解其影响并做出相应的决策。

这些命令用于禁用或停止一些服务，具体解释如：

chkconfig rpcbind off
chkconfig printer off
chkconfig tftp off
chkconfig lpd off
chkconfig nfs off
chkconfig nfslock off
chkconfig ypbind off
chkconfig daytime off
chkconfig daytime-udp off
chkconfig sendmail off
chkconfig ntalk off
chkconfig ident off
chkconfig bootps off
chkconfig kshell off
chkconfig klogin off
chkconfig snmpd off
chkconfig time off
chkconfig time-udp off
chkconfig echo off
chkconfig echo-udp off
chkconfig discard off
chkconfig discard-udp off
chkconfig chargen off
chkconfig chargen-udp off

使用`chkconfig`命令将rpcbind、printer、tftp、lpd、nfs、nfslock、ypbind、daytime、daytime-udp、sendmail、ntalk、ident、bootps、kshell、klogin、snmpd、time、time-udp、echo、echo-udp、discard、discard-udp、chargen和chargen-udp服务的自动启动设置为关闭。

systemctl disable rpcbind
systemctl disable printer
systemctl disable tftp
systemctl disable lpd
systemctl disable nfs
systemctl disable nfslock
systemctl disable ypbind
systemctl disable daytime
systemctl disable daytime-udp
systemctl disable sendmail
systemctl disable ntalk
systemctl disable ident
systemctl disable bootps
systemctl disable kshell
systemctl disable klogin
systemctl disable snmpd
systemctl disable time
systemctl disable time-udp
systemctl disable echo
systemctl disable echo-udp
systemctl disable discard
systemctl disable discard-udp
systemctl disable chargen
systemctl disable chargen-udp

使用`systemctl`命令将rpcbind、printer、tftp、lpd、nfs、nfslock、ypbind、daytime、daytime-udp、sendmail、ntalk、ident、bootps、kshell、klogin、snmpd、time、time-udp、echo、echo-udp、discard、discard-udp、chargen和chargen-udp服务的自动启动设置为禁用。

service rpcbind stop
service snmpd stop
systemctl stop telnet.socket
systemctl stop rlogin
systemctl stop rpcbind

使用`service`和`systemctl`命令停止rpcbind、snmpd、telnet.socket和rlogin服务。

"Run the following commands to disable `daytime` -dgram and `daytime` -stream: ``` # chkconfig daytime-dgram off # chkconfig daytime-stream off ```"

这条指令包含两个部分：

第一部分是运行以下命令来禁用 `daytime-dgram`：

# chkconfig daytime-dgram off

`chkconfig` 是一个命令行工具，用于管理系统服务的启动和停止。在这个例子中，我们使用 `chkconfig` 命令将 `daytime-dgram` 服务的自动启动设置为禁用。这是一种良好的安全实践，因为 `daytime-dgram` 服务可能会被攻击者利用来进行 DDoS 攻击。请注意，此命令需要使用 root 用户权限才能执行。

第二部分是运行以下命令来禁用 `daytime-stream`：

# chkconfig daytime-stream off

`chkconfig` 命令的用法与第一部分相同，我们使用 `chkconfig` 命令来禁用 `daytime-stream` 服务的自动启动。同样，这是一种良好的安全实践，因为 `daytime-stream` 服务也可能会被攻击者利用来进行 DDoS 攻击。请注意，此命令需要使用 root 用户权限才能执行。
