sometimes things are not as stable and not-leaky as they should be.
we needed to do some interoperability testing, and for that we had to allow http client application to talk with http proxy via secure channel. on debian 11 i had to install package squid-openssl and add this line in /etc/squid/squid.conf: the ssl cert was generated by certbot certonly. that’s how i tested it:
sadly, not all of our logs are in clickhouse, meaning chewing them can be time consuming and not-so-fun.
once in a while i need to review which database accounts are used, from what IPs connections arrive. MySQL / MariaDB does not have built-in mechanism [ unless you want to allow full query log ], but there’s quite easy way to get the data.
once in a while i’m involed in moving mail servers around, to and from the could. those tools are useful each time it’s done:
rsync 3.2.0 and newer supports more compression and hash algorithms. zstd compression is well suited for slower network connections [ tens mbit/s ], lz4 – for faster. xxh3 hash is worth using regardless of the network speed. syntax:
i needed to monitor some service available via HTTP, this service is expecting to get a file posted – as if it was submitted via HTML form. so the file’s content is in the POST body, wrapped in Content-Type: multipart/form-data and stored between boundaries.
