KEY.DNS_RESOLVER(8)

💖 KEY.DNS_RESOLVER(8) 💖

okay bestie, gather round, because this is the key.dns_resolver page from the Linux Key Management Utilities and it's literally the backstage crew of your hostname lookups 🎀

✨ NAME ✨

key.dns_resolver — the upcall for request-key that handles dns_resolver keys 🦋

🌸 SYNOPSIS 🌸

/sbin/key.dns_resolver <key>
/sbin/key.dns_resolver --dump-config [-c <configfile>]
/sbin/key.dns_resolver -D [-v] [-v] [-c <configfile>] <desc>
<calloutinfo>

💅 DESCRIPTION 💅

okay so here's the tea ☕ — this program gets invoked by request-key on behalf of the kernel whenever kernel services (think NFS, CIFS and AFS, the whole squad) wanna do a hostname lookup and the kernel doesn't have the key cached yet. it's giving "emergency backup dancer." and ngl, it is not ordinarily meant to be called directly, so don't just go running it for funsies 🙈

the program has internal parameters, and you can change them with a configuration file (peep key.dns_resolver.conf(5) for more info, iykyk). the default configuration file lives in /etc, but bestie you can override that with the -c flag 💫

you can also call the program in debugging mode to test its functionality by passing a -D or --debug flag on the command line. for that to actually work, the key description and the callout information must be supplied — no skipping steps, queen 👑. and if you want it extra chatty, just supply one or more -v flags. verbosity goes up, vibe goes up 📈

the program may also be called with --dump-config to show the values that configurable parameters will have after parsing the config file. it's the "what's in my bag" reveal but for config 🎀✨

😭 ERRORS 😭

all errors will be logged to the syslog. every single one. no secrets here, it's all going in the group chat 📝

🔥 SEE ALSO 🔥

• key.dns_resolver.conf(5)
• request-key.conf(5)
• keyrings(7)
• request-key(8)

lowkey important reminder bestie: this is an upcall handler, so if you're calling it by hand, you're probably doing it for debugging reasons. <desc> and <calloutinfo> are not optional in debug mode, fr fr 💀

and that's the whole page, mwah 💋 this one's from the Linux key management utilities, dated 18 May 2020, and it's filed under KEY.DNS_RESOLVER(8) — periodt. go forth and resolve those hostnames, main character 💖✨🦋
