ISNSD(8)

💖 ISNSD(8) — the iSNS server daemon, bestie edition 💖

okay so. this is the manual page for isnsd, section 8 of the System Manager's Manual, and I'm gonna walk you through it like we're texting at 1am. grab a snack. 🍓

✨ NAME ✨

isnsd — the iSNS server daemon. that's it. that's the whole name. short king behavior. 👑

✨ SYNOPSIS ✨

isnsd [-f] [-4] [-6] [-c filename] [-d debug-facility] [--dump-db]
[--init]

look at all those little flags. iconic honestly. let's get into it. 💅

✨ DESCRIPTION ✨

So Isnsd implements the iSNS protocol exactly as it's defined in RFC 4171. and what IS iSNS, you ask? it's a discovery protocol for iSCSI and iFCP. that's the whole vibe. it finds stuff for you. no cap. ✨

✨ OPTIONS ✨

fr fr, by default isnsd takes most of its settings from the configuration file /etc/isns/isnsd.conf — with the exception of the following options, which are the ones you get to boss around directly. 🫶

• --config filename, -c filename — this one overrides the default configuration file. you want a different conf? say less, bestie.
• --foreground, -f — by default, isnsd puts itself into the background (main character move, it doesn't want to be perceived). but with this option you can tell it to run in the foreground instead. bonus: any error messages or debug output get printed to the console rather than being sent to syslog. so you actually see them. 🙈
• -4 — tells isnsd to create an IPv4 socket only. normally it defaults to IPv6, which (fun fact) will accept both IPv4 and IPv6 connections. so this is you being like "no, IPv4 only, I said what I said." 💀
• -6 — tells isnsd explicitly to create an IPv6 socket only. and since it defaults to IPv6 anyway… this is really a no-op. it's giving "confirming the plan we already had." 😭 still valid though!
• --debug facility, -d facility — enables debugging. valid facilities are:
  • socket — network send/receive
  • auth — authentication and security related information
  • message — iSNS protocol layer
  • state — database state
  • scn — SCN (state change notification) messages
  • esi — ESI (entity status inquiry) messages
  • all — all of the above (the greedy option, we love her) 💖
• --dump-db — a helper function that reads the database from the file system and displays it in human readable form. when you use this option, isnsd will not open any sockets, and it terminates immediately after displaying the database. this one is intended to be used by the administrator when they're suspecting the database contains bad/inconsistent information. it's giving detective energy. 🔍
• --init — this option creates the server's authentication key, plus the required DSA parameters. the private key gets stored in the file specified by the AuthKey option (usually /etc/isns/auth_key). the public portion of the key is written to the same directory, with the suffix .pub appended to the key file name. so you end up with the key and the key dot pub. slay. 🎀

heads up bestie: those two helper options (--dump-db and --init) are doing their own little thing and then dipping — --dump-db doesn't even open sockets. don't expect a running server out of them.
