2024-12-29Better ns0 network namespace configsXiao Pan
Enable nft. Use different nft config for ns0. Host open emails port. ns0 open wireguard and qbt ports. ns0 configure wireguard. host not configure wiregurad, so also no need ip forwarding sysctl kernel parameters. ns0 use /etc/netns/ns0/nftables.conf that will bind mount to ns0. Host and ns0 both run dnsmasq for dns cache. ns0 dnsmasq I disable dbus because it will conficts with host dnsmasq dbus. Dnsmasq use dbus for config cahnge? I disable systemd-resolved and switch to dnsmasq because systemd-resolved use dbus for dns query? which is maybe easy for dns leak, e.g., when systemd-resolved is only running on host, ns0 with different /etc/resolv.conf still get dns from host open public ip when run resolvectl query, although drill does not leak. sye add enabled systemd units

Note I also change opt-level to 3 because https://doc.rust-lang.org/cargo/reference/profiles.html shows opt-level 3 is all optimization which I want.

dovecot no auto delete Junk, read junk first to determine if it is spam. Trash only auto delete after 10 days, because consider in the future I may only do backup weekly, 10 days can make sure it is backuped.

postfix log warning "/etc/postfix/main.cf: support for parameter "smtpd_use_tls" will be removed; instead, specify "smtpd_tls_security_level"". I am already using smtpd_tls_security_level, so I just removed smtpd_use_tls. Also see https://github.com/LukeSmithxyz/emailwiz/issues/112 `man 5 postconf` has documentation about smtpd_tls_security_level

2024-04-18sshd accept COLORTERM env to fix ls no colorXiao Pan
If client use alacritty, after ssh into this remote server, ls doesn't show color. Can be workarounded by server sshd accept COLORTERM and client sshd send env. More see my comments in alacritty.toml config.
