Hello!As you probably know, F5 closed Moscow office in 2022, and I no longer work for F5 since then. Still, we’ve reached an agreement that I will maintain my role in nginx development as a volunteer. And for almost two years I was working on improving nginx and making it better for everyone, for free.Unfortunately, some new non-technical management at F5 recently decided that they know better how to run open source projects. In particular, they decided to interfere with security policy nginx uses for years, ignoring both the policy and developers’ position.That’s quite understandable: they ...继续阅读 (32)

Rspamd is an advanced spam filtering system and email processing framework that allows evaluation of messages by a number of rules including regular expressions, statistical analysis and custom services such as URL black lists. Each message is analysed by Rspamd and given a verdict that might be used by MTA for further processing (e.g. to reject a message, or add a special header indicating spam) along with other information, such as possible DKIM signature or modifications suggested for a message.Rspamd can act as a Milter allowing direct interaction with popular MTA systems, such as Postfix ...继续阅读 (61)

kexec是Linux内核的一种机制，它允许从当前运行的内核启动新内核。kexec会跳过由系统固件执行的引导加载程序阶段和硬件初始化阶段，直接将新内核加载到主内存并立即开始执行。这避免了与完全重新启动相关的漫长时间，并且可以通过最小化停机时间来帮助系统满足高可用性要求。moreDebian默认支持kexec，所以在Debian下我们只要安装kexec-tools就行了。apt install kexec-tools检查当前的内核banbroot@jp:~# uname -r 5.10.0-17-amd64查找目前可用的内核版本root@jp:~# ls /boot/vmlinuz-* /boot/vmlinuz-5.10.0-16-amd64 /boot/vmlinuz-5.10.0-17-amd64 /boot/vmlinuz-5.10.0-18-amd64这里最新的是 /boot/vmlinuz-5.10.0-18-amd64先查看当前内核5.10.0-17-amd64的引导参数root@jp:~# cat /boot/grub/grub.cfg | grep 5.10.0-17-amd64 echo 'Loading Linux 5.10.0-17-amd64 ...' linux /boot/vm ...继续阅读 (53)
