✨ pptp_selinux ✨

okay bestie, so you want to know about SELinux policy for pptp? say less, i got you 💅 this is the manual page for pptp_selinux, and it's literally all about keeping your pptp processes secure and cute. no cap, this is important stuff.

---

💖 NAME 💖

pptp_selinux — the Security Enhanced Linux Policy for real, for the pptp processes. periodt.

---

🦋 DESCRIPTION 🦋

so like, Security-Enhanced Linux secures the pptp processes via flexible mandatory access control. it's giving protective bestie energy, honestly. 🫶

the pptp processes execute with the pptp_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 pptp_t

---

🌸 ENTRYPOINTS 🌸

the pptp_t SELinux type can be entered via the pptp_exec_t file type. that's the gateway, the main character entrance, if you will.

the default entrypoint paths for the pptp_t domain are the following:

/usr/bin/pptp

---

🎀 PROCESS TYPES 🎀

SELinux defines process types (domains) for each process running on the system. yes, every single one gets its own vibe check.

you can see the context of a process using the -Z option to ps. iconic, truly.

Policy governs the access confined processes have to files. SELinux pptp policy is very flexible allowing users to setup their pptp processes in as secure a method as possible. slay for customizable security 🔥

the following process types are defined for pptp:

pptp_t

Note: semanage permissive -a pptp_t can be used to make the process type pptp_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it's still watching you, just not blocking. iykyk 👀

---

🧚 BOOLEANS 🧚

SELinux policy is customizable based on least access required. pptp policy is extremely flexible and has several booleans that allow you to manipulate the policy and run pptp with the tightest access possible. we love a configurable queen 👑

• daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

• fips_mode — 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

• nis_enabled — if you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

---

🌈 PORT TYPES 🌈

SELinux defines port types to represent TCP and UDP ports. ports are like the doorways, and SELinux is the bouncer checking IDs. 💅

you can see the types associated with a port by using the following command:

semanage port -l

Policy governs the access confined processes have to these ports. SELinux pptp policy is very flexible allowing users to setup their pptp processes in as secure a method as possible. again with the flexibility, we stan 🫶

the following port types are defined for pptp:

pptp_port_t

Default Defined Ports:

tcp 1723
udp 1723

---

💜 MANAGED FILES 💜

the SELinux process type pptp_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. note: the processes UID still need to have DAC permissions. so like, SELinux isn't doing everything, your user permissions still matter, bestie.

cluster_conf_t

/etc/cluster(/.*)?

cluster_var_lib_t

/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?

⭐ FILE CONTEXTS ⭐

SELinux requires files to have an extended attribute to define the file type. it's like giving every file a little name tag, cute right? 🎀

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 pptp policy is very flexible allowing users to setup their pptp processes in as secure a method as possible. (yes, again. we get it, it's flexible. and we love that for us 💅)

🌸 STANDARD FILE CONTEXT 🌸

SELinux defines the file context types for the pptp, 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. it's a two-step process, bestie, don't skip steps.

semanage fcontext -a -t pptp_exec_t '/srv/pptp/content(/.*)?'
restorecon -R -v /srv/mypptp_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex is iconic and powerful, just like you 🫶

the following file types are defined for pptp:

• pptp_exec_t — set files with the pptp_exec_t type, if you want to transition an executable to the pptp_t domain. this is the glow-up pipeline for your executable ✨
• pptp_log_t — set files with the pptp_log_t type, if you want to treat the data as pptp log data, usually stored under the /var/log directory. logs are the receipts, and now they have a label 💅
• pptp_var_run_t — set files with the pptp_var_run_t type, if you want to store the pptp files under the /run or /var/run directory. runtime files need love too 💖

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 a quick fix, semanage fcontext + restorecon is the forever solution. choose wisely 😌

---

🔥 COMMANDS 🔥

semanage fcontext can also be used to manipulate default file context mappings. it's multifunctional, flexible, a real one.

semanage permissive can also be used to manipulate whether or not a process type is permissive. you decide who gets a pass 👑

semanage module can also be used to enable/disable/install/remove policy modules. module management, we love to see it.

semanage port can also be used to manipulate the port definitions. ports need managing too, bestie.

semanage boolean can also be used to manipulate the booleans. booleans are like little on/off switches for policy behavior, and you get to flip them 🔘

system-config-selinux is a GUI tool available to customize SELinux policy settings. for when you want to click buttons instead of typing commands, no judgment here 🖱️
