motd
motd
is a crate for printing the current MOTD (message of the day)
on linux. Most of the logic lives in the motd
crate, and the dump-motd
tool is a thin wrapper which provides a command line interface for the
crate.
Dependencies
You must install libpam headers to build this crate. On debian based systems you can do so with
sudo apt-get install libpam0g-dev
Features
There are two modes of operation for the motd
crate. By default, it
will load and call into the pam_motd.so
file used by the pam stack,
but you can instead use a pure rust reimplementation of the logic found
in pam_motd.so
if you want. The downside of the pure rust implementation
is that it no longer uses the same source-of-truth logic to resolve the
motd, though this is likely not a huge deal because pam_motd
is fairly
stable. The pure rust implementation has the advantages that it uses zero
unsafe code, does not require a (sometimes slow) directory walk to
locate pam_motd.so
the first time it is run, and requires many fewer
dependencies.
The feature for calling pam_motd.so
directly is socall
, and it is
enabled by default. To use the pure rust implementation, disable
default features. This will change the signature of a few functions.
