- yjftsjthsd-h 3y agoIIRC, xz was used by a systemd library, and that systemd library got added to sshd so it could tell systemd when it had started or something like that. SSH itself doesn't use xz.
- riddley 3y agoxz is a compression library.
- yjftsjthsd-h 3y agoI'm aware? It's a compression library that is used by systemd, including in a systemd library that got added to sshd in some distros.
- fullstop 3y agossh out of the box also does not use libsystemd, except on systems which were patched to do so.
- pwg 3y agoSSH does not support/use lzma/xz compression method for the SSH protocol. The xz linkage was indirect through a systemd library that some systemd systems link into sshd.
