VDE_TUNCTL(8)

💖 VDE_TUNCTL(8) 💖

okay so bestie, this is a page from the System Manager's Manual — pull up a chair, we're doing TUN/TAP devices and honestly? it's giving main character energy 🎀

✨ NAME ✨

vde_tunctl</pura> — create and manage persistent TUN/TAP interfaces 🦋

✨ SYNOPSIS ✨

vde_tunctl [-f clone-dev] [-u owner] [-g group] [-n] [-t dev-name]

vde_tunctl [-f clone-dev] -d dev-name

✨ DESCRIPTION ✨

So like, vde_tunctl lets the host sysadmin (that's you, queen 👑) preconfigure a TUN/TAP device for use by a particular user. That user can open the device and use it — slay — but they cannot change any aspects of the host side of the interface. Boundaries, periodt. 💅

vde_tunctl is an extension of tunctl. It's the glow-up, fr fr. ✨

And here's the lil rule about what kind of interface you get: vde_tunctl defines tap interfaces unless dev-name begins by "tun" or the option -n appears in the command line. iykyk 🧚

✨ USAGE ✨

Wanna create an interface for a particular user? Invoke tunctl without the -d option:

# vde_tunctl -u someuser
Set 'tap0' persistent and owned by uid 500

Then, configure the interface as normal — like, business as usual bestie:

# ifconfig tap0 192.168.0.254 up
# route add -host 192.168.0.253 dev tap0
# bash -c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp'
# arp -Ds 192.168.0.253 eth0 pub

To delete the interface, use the -d option:

# vde_tunctl -d tap0
Set 'tap0' nonpersistent

And to create or destroy a tun interface (instead of tap), it's this:

# vde_tunctl -n -u someuser
Set 'tun0' persistent and owned by uid 500
# vde_tunctl -d tun0
Set 'tun0' nonpersistent

heads up bestie — those commands go in exactly as written, no cap. Copy them character for character 🙈
