Service Bloat
I have (finally) upgraded my home workstation/server/router to Fedora 22. Newer Fedora releases have an anti-feature called "product": one cannot simply install "Fedora", the "Fedora Product", such as Fedora Workstation, should be selected first. For a system with X session (two X sessions, in my case), "Fedora Workstation" seems to be a natural choice. It is not: "Fedora Workstation" can be translated from Fedora Newspeak to an ordinary English as "Fedora GNOME 3". So this is a no-go.
A time ago, I came across a suggestion that "Fedora Server" is probably
the closest thing to former "Fedora". So I upgraded my home box to
"Fedora Server". Today, after a routine inspection of open ports on my
home server, I discovered that something is listening on port 9090
on INADDR_ANY (and IN6ADDR_ANY as well). One fuser -n tcp,
and I discovered that the listening process is called cockpit-ws.
Digging further into it, it seems that this is a web-based administrative
interface (do you remember linuxconf, anyone?), probably another futile
attempt to encapsulate the strength of all the configuration files to some
useless web-based interface. Moreover, it cannot be uninstalled, as it
depends on the fedora-release-server package.
A side note: the cockpit-ws package contains font files,
which is probably against Fedora Font Packaging Guidelines.
I wonder what happened to the "no unnecessary services should be enabled by default" philosophy. It seems that Cockpit is a blatant example of an unnecessary service, which is not only installed by default, but also enabled by default in Fedora Server 22. I recommend to run the following commands:
# systemctl stop cockpit.socket # systemctl disable cockpit.socket
What other kinds of service-bloat did you find on your computers? Watch for newly opened ports after Fedora upgrades.
