ftpdctl_selinux(8)

okay so bestie, welcome to the ftpdctl_selinux(8) manual page 💅 — it's literally the SELinux policy page for ftpdctl, and we are gonna get into it, no cap 🫶✨

✨ NAME ✨

ftpdctl_selinux — Security Enhanced Linux Policy for the ftpdctl processes. That's the whole vibe: it's the SELinux policy for ftpdctl, periodt 💖.

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the ftpdctl processes via flexible mandatory access control. Iconic behaviour, honestly.

The ftpdctl processes execute with the ftpdctl_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep ftpdctl_t

🦋 ENTRYPOINTS 🦋

The ftpdctl_t SELinux type can be entered via the ftpdctl_exec_t file type. That's the doorway, iykyk 🚪✨.

The default entrypoint paths for the ftpdctl_t domain are the following:

/usr/bin/ftpdctl

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. Main character energy for every single process, honestly.

You can see the context of a process using the -Z option to ps.

Policy governs the access confined processes have to files. SELinux ftpdctl policy is very flexible, allowing users to setup their ftpdctl processes in as secure a method as possible.

The following process types are defined for ftpdctl:

ftpdctl_t

Note: semanage permissive -a ftpdctl_t can be used to make the process type ftpdctl_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So like, it's not a free pass — the receipts still show up 😭.

💅 BOOLEANS 💅

SELinux policy is customizable based on least access required. ftpdctl policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ftpdctl with the tightest access possible. Tightest access = the look, obviously.

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

🎀 FILE CONTEXTS 🎀

SELinux requires files to have an extended attribute to define the file type. It's the file's little label, bestie 🏷️✨.

You can see the context of a file using the -Z option to ls.

Policy governs the access confined processes have to these files. SELinux ftpdctl policy is very flexible, allowing users to setup their ftpdctl processes in as secure a method as possible.

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the ftpdctl, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t ftpdctl_exec_t '/srv/ftpdctl/content(/.*)?'
restorecon -R -v /srv/myftpdctl_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies stay winning 🌈.

The following file types are defined for ftpdctl:

• ftpdctl_exec_t — Set files with the ftpdctl_exec_t type, if you want to transition an executable to the ftpdctl_t domain. Slay that transition ✨.
• ftpdctl_tmp_t — Set files with the ftpdctl_tmp_t type, if you want to store ftpdctl temporary files in the /tmp directories. Temp files but make it labeled 💖.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels. So like, chcon is the quick fix, semanage fcontext + restorecon is the permanent glow-up 💅.

🌟 COMMANDS 🌟

• semanage fcontext can also be used to manipulate default file context mappings.
• semanage permissive can also be used to manipulate whether or not a process type is permissive.
• semanage module can also be used to enable/disable/install/remove policy modules.
• semanage boolean can also be used to manipulate the booleans.
• system-config-selinux is a GUI tool available to customize SELinux policy settings.
