MPTCPIZE(8)

💖 MPTCPIZE(8) 💖

okay bestie, so you know how some services are stuck in their TCP era? mptcpize is literally the glow-up they need. it's a program from the System Management Commands corner of your system that turns on multipath TCP for existing legacy services. no rewrite, no drama, just vibes. ✨

and COMMAND has to be one of these three, no cap:

🌸 the commands

🦋 run [-d] prog [args]

runs the target program with the exact command line arguments you give it, but forcing MPTCP socket usage instead of TCP. slay.

and if you pass the -d argument? it dumps messages on stderr whenever a TCP socket gets forced to use MPTCP. so you can literally watch it happen. iykyk. 👑

🎀 enable unit

updates the systemd unit file, forcing the given service to run under the launcher from above. main character energy for your service fr fr.

🧚 disable unit

updates the systemd unit file, removing that launcher. it's giving... closure. 💅

✨ OPTIONS ✨

mptcpize</purl> accepts the following command line options, bestie:

• -?, --help — displays mptcpize help information 💖
• --usage — displays brief mptcpize usage information 🌸
• -V, --version — displays mptcpize version information ⭐

lowkey important: the synopsis is mptcpize [-?V] [--help] [--usage] [--version] COMMAND, so yes, you can stack -?V like that. iconic behavior honestly.
