KPROP(8)

💖 KPROP(8) 💖

okay bestie, welcome to the MIT Kerberos manual, section 8, and today's main character is kprop — she's the one who carries your whole database across the internet and hands it to your backup server. iconic behaviour, honestly. 🫶

✨ NAME ✨

kprop — propagate a Kerberos V5 principal database to a replica server 🌸

---

🦋 SYNOPSIS 🦋

kprop [-r realm] [-f file] [-d] [-P port] [-s keytab] replica_host

---

💅 DESCRIPTION 💅

So kprop is the girl who does the secure drop-off. She takes a Kerberos V5 database dump file from the primary Kerberos server and propagates it over to a replica Kerberos server — and which replica? That's literally what replica_host is for, she's not guessing. 🎀

⚠️ okay but fr fr, the dump file has to be created by kdb5_util first. Don't show up with a random file, she will not be vibing with that. 💀

---

⭐ OPTIONS ⭐

• -r realm — tells her which realm the primary server is repping. pick your realm, bestie. 👑
• -f file — the filename where the dumped principal database file is hanging out. by default the dumped database file is normally /var/kerberos/krb5kdc/replica_datatrans ✨
• -P port — the port she uses to contact the kpropd server on the remote host. so like, which door are we knocking on. 🚪
• -d — prints debugging information. she gets chatty, she tells you everything she's doing. lowkey the best setting for when things are weird. 🔥
• -s keytab — the location of the keytab file. yes, that keytab. don't lose it. 😭
