铁威马的系统配置和常见Linux系统配置不一样，搞了好半天。
假设需要启用IPv6的网卡为eth1
编辑 /etc/network 添加或修改配置为：
[eth1]
SLAVE=0
MTU=1500
DHCP=YES
IPV6_CONF=auto
IPV6_DEFROUTE=yes
IPV6INIT=YES
MtuStatus=0
echo 0 > /proc/sys/net/ipv6/conf/eth1/disable_ipv6
DHCP 获取IP
killall -2 nasips
因为要配置防火墙，需要固定NFS mount的绑定端口。之前的做法是配置/etc/default/nfs-kernel-server，配置RPCMOUNTDOPTS="--manage-gids -p 2050"。现在该配置文件已经失效，需要修改/etc/nfs.conf
[mountd]
# debug="all|auth|call|general|parse"
manage-gids=y
# descriptors=0
port=2050
| TCP Port | Where | Notes |
|---|---|---|
| 443 | vCenter Server, ESXi Host | Default port used for connections to VMware infrastructure (vCenter server and ESXi host). Must be opened on vCenter Servers and ESXi hosts. |
| 902 | ESXi Host | Port used for data transfer and moving. Must be opened on ESXi hosts. |

本文规定了 OI Wiki 中数学符号的推荐写法，并给出了一些应用范例。
本文参考了 GB/T 3102.11-1993 和 ISO 80000-2:2019 修订，故基本与国内通行教材的符号体系兼容。
符号的 LaTeX 写法请参考 本文章的源代码
| 编号 | 符号，表达式 | 意义，等同表述 | 备注与示例 |
|---|---|---|---|
| n1.1 | $p \land q$ | $p$ 和 $q$ 的合取 | $p$ 与 $q$. |
| n1.2 | $p \lor q$ | $p$ 和 $q$ 的析取 | $p$ 或 $q$;此处的 “或” 是包含的，即若 $p$，$q$ 中有一个为真陈述，则 $p \lor q$ 为真。 |
| n1.3 | $\lnot p$ | $p$ 的否定 | 非 $p$. |
| n1.4 | $p \implies q$ | $p$ 蕴含 $q$;若 $p$ 为真，则 $q$ 为真 | $q \impliedby p$ 和 $p \implies q$ 同义。 |
| n1.5 | $p \iff q$ | $p$ 等价于 $q$ | $(p \implies q) \land (q \implies p)$ 和 $p \iff q$ 同义。 |
| n1.6 | $(\forall~x \in A)~~p(x)$ | 对 $A$ 中所有的 $x$, 命题 $p(x)$ 均为真 | 如果从上下文中可以得知考虑的是哪个集合 $A$, 可以使用记号 $(\forall~x)~~p(x)$.$\forall$ 称为全称量词。 $x \in A$ 的含义见 n2.1. |
| n1.7 | $(\exists~x \in A)~~p(x)$ | 存在一个属于 $A$ 的 $x$ 使得 $p(x)$ 为真 | 如果从上下文中可以得知考虑的是哪个集合 $A$, 可以使用记号 $(\exists~x)~~p(x)$.$\exists$ 称为存在量词。 $x \in A$ 的含义见 n2.1. $(\exists!~x)~~p(x)$（唯一量词）用来表示恰有一个 $x$ 使得 $p(x)$ 为真。 $\exists!$ 也可以写作 $\exists^1$. |

创建Admin账号
sudo runuser -u _gvm -- gvmd --create-user=Admin --new-password=12345
重置Admin密码
sudo runuser -u _gvm -- gvmd --user=Admin --new-password=12345
应用目录下storage/app/backup-temp的所有者是root，改成www-data即可。
登录Hermes SEG提示要做动态口令认证，因为是测试环境，所以决定取消该认证。
Register device
因为无法登录网页控制台，所以通过修改数据库修改配置。结果发现"access_control" 是"one_factor"，用户配置并没有开启。
ESXi的评估许可只有60天，如果不想重装虚拟环境的话，可以重置评估许可。操作如下：
rm -r /etc/vmware/license.cfgcp /etc/vmware/.#license.cfg /etc/vmware/license.cfg/etc/init.d/vpxa restartbootfile-name bootnetx64.efi
next-server 10.0.2.2
H3C交换机DHCP配置中关于PXE的部分，bootfile-name是启动文件，next-server是PXE服务器。
