回复了 PowerDi 创建的主题 Windows 无法排查的内存溢出问题
这个我懂,任务管理器转到性能页面->内存页,查看"已提交"是不是接近满了。这个是 chrome 系搞出来的问题。

回复了 VMRack 创建的主题 VPS VMRack 关于流量服务故障的致歉 !
原来是把服务更改了,原来的单向不限量流量改成双向计流量了,这是欺负买家大多是瓷器国的吧,要是美国用户那得起诉了
这插件有个好处可以自己导出数据到本地,也可以导入备份。
目前好像没有其他插件支持这个功能
@iamwin su 可以,但是传统的 login 不能以传统的方式用了
找到了更多信息

A recursive login, as used to be possible in the good old days, no longer works; for most purposes [su]( https://manpages.ubuntu.com/manpages/plucky/man1/su.1.html)
is a satisfactory substitute. Indeed, for security reasons, login does a [vhangup]( https://manpages.ubuntu.com/manpages/plucky/man2/vhangup.2.html) system call to remove
any possible listening processes on the tty. This is to avoid password sniffing. If one uses the command
login, then the surrounding shell gets killed by [vhangup]( https://manpages.ubuntu.com/manpages/plucky/man2/vhangup.2.html) because it’s no longer the true owner of the
tty. This can be avoided by using exec login in a top-level shell or xterm.
以前查过 release notes ,没写到这点。搜索也不易找到。
用这样的关键词才找到一点 "debian 13 login shadow-utils util-linux"
结果有条 Debian Trixie: Nested Logins Always Failing

测试过了,没法登录到其他用户,这么重要的 breaking change 居然没有记录
