2022 Feb. 23 (Wed.) [qmail] badmailfrom
_ [server] antiSPAM
いい加減 SMAP にうんざりなので管理下の qmail の
設定
badmailfrom
に、もういいやと思って
.cn .biz .work .cloud
と記述。
翌日 log をみてみる
cat /var/log/maillog| grep badmailfrom| awk '{print $9}'
と、それっぽいものが抑止されていてゆけている気も
しましたが、
@biscuit.ocn.ne.jp @sage.ocn.ne.jp @return.nmc.smbcnikko.co.jp
とかも抵触しているようで、どうやら badmailfrom
は正規表現が効いてくれるみたい。

2021 Dec. 20 (Mon.) TeraTerm & mysql: 漢字 / 日本語 入力
_ [server] 背景
where 句に日本語が入っている sql
select * from customer where username='漢字'\G
をコピペしたら、漢字部分が反映されなかった。
ので
select * from customer where username=''\G
となる。
_ 環境
shell 自体では漢字は入力できるし、DB は下記で、
問題ないようにみえる。
mysql> show variables like '%char%'; +--------------------------------------+----------------------------+ | Variable_name | Value | +--------------------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | | validate_password_special_char_count | 1 | +--------------------------------------+----------------------------+ 9 rows in set (0.01 sec)
