SMCROUTE(8)

✨ SMCROUTE ✨

okay bestie, gather round 💖 this is the smcroute command — literally the command-line front door for SMCRoute, the multicast routing queen 👑. (the manual page calls her smcroute, and honestly? iconic. no notes.)

---

🌸 SYNOPSIS 🌸

smcroute [OPTIONS] [ARGS]

that's it, that's the shape of it ✨ options, then args, in that order, no cap.

---

💅 DESCRIPTION 💅

so here's the whole vibe check on the flags, one by one, and I'm giving you every single one because we do not gatekeep 🫶

• -d — start daemon. she's up, she's running, main character energy 🔥
• -k — kill a running daemon. okay we're shutting her down, respectfully 💀
• -h — this help text. your girl is lost, this is the map 🗺️✨
• -v — show version. gotta know which era we're in 🎀
• -a ARGS — add a multicast route. new route just dropped 🌈
• -r ARGS — remove a multicast route. bye bestie, we won't miss you 😭
• -j ARGS — join a multicast group. we're in the group chat now 👑
• -l ARGS — leave a multicast group. muted, not blocked, it's giving boundaries 🙈

🦋 the actual shapes 🦋

okay so here's the part where it shows you the literal traffic flow, inbound on the left, outbound on the right, and I am obsessed with the diagram:

<------------- INBOUND -------------->
       <----- OUTBOUND ------>

so pretty. so directional. ⭐

and here's how the add/remove/join/leave flags actually lay out with their args:

-a <IFNAME> <SOURCE-IP> <MULTICAST-GROUP>
       <IFNAME> [<IFNAME> ...]

-r <IFNAME> <SOURCE-IP> <MULTICAST-GROUP>

-j <IFNAME> <MULTICAST-GROUP>

-l <IFNAME> <MULTICAST-GROUP>

so like — -a takes an interface, a source IP, a multicast group, and then one or more more interfaces (note the [<IFNAME> ...], that's plural, she's flexible 💖). -r takes an interface, source IP and multicast group. -j and -l are simpler — just an interface and a multicast group, because joining and leaving don't need to know where the packets came from, iykyk 🧚

🎀 NOTE 🎀

NOTE: This is a compatibility wrapper script for SMCRoute. Intended for use with old style startup scripts.

and then, because she cares about you:

It is recommended to migrate to /etc/smcroute.conf, see the smcroute(8) man page for help. 🌸

like — the wrapper is the old way, /etc/smcroute.conf is the glow-up. she said please move on, for me 💜

🌈 SEE YA 🌈

okay that's the whole page bestie, and this is smcroute version 2.5.7, dated May 2024, from the SMCROUTE(8) family — System Administration Utilities energy through and through 💅✨ slay, go route some multicast, and hydrate 🍓🫶
