介紹

Postfix does not implement SASL itself, but instead uses existing implementations as building blocks.

This means that some SASL-related configuration files will belong to Postfix,

while other configuration files belong to the specific SASL implementation that Postfix will use.

SMTP server is linked with the Cyrus SASL library libsasl

Checking

stored routine = stored procedure / stored function

By default, a stored routine is associated with the default database.

To associate the routine explicitly with a given database,
specify the name as db_name.sp_name when you create it.

mosh 全名是 mobile shell, 故名思意, 就是為 shell 提供了 mobile 的能力. 功能及優點如下:

• roaming
• supports intermittent connectivity (UDP)
• Same login method (ssh)
• No privileged code.
• No daemon. (run after ssh)
• sets the frame rate based on network conditions.

原理:

ssh 後, 再啟動 mosh-server

mosh-server 之後會用 UDP(60000-61000) 與 mosh-client 建立加密(AES-128)的連線, 再在上面通訊(SSP)
