KEY.DNS_RESOLVER.CONF(5)

💖 KEY.DNS_RESOLVER.CONF(5) 💖

okay bestie, welcome to the Linux Key Management Utilities corner of the man pages ✨ this one's called key.dns_resolver.conf and it's literally just the config file situation for the kernel DNS resolver. sit down, grab a strawberry 🍓, we're doing this.

🌸 NAME 🌸

key.dns_resolver.conf — Kernel DNS resolver config 👑

🦋 DESCRIPTION 🦋

so this file? it's the one the key.dns_resolver(5) program reads to set its parameters. unless you've overridden it with the -c flag (iconic behaviour, respect), the program reads:

/etc/key.dns_resolver.conf

the config options go in key[=value] form, and ngl the value part is optional. if you do put a value in, you can wrap it in a pair of single quotes ('') or double quotes ("") and those quotes just get stripped right off. 💅 and if your value has special characters that are being weird about it, you can escape them with a backslash to turn them into ordinary, well-behaved little characters.

lines that start with a # are comments, full stop, ignored, not the moment. 🚫 and a # symbol anywhere after the = turns the rest of that line into a comment too — unless the # is chillin' inside a quoted section or you escaped it. iykyk.

leading and trailing spaces, plus spaces around the = symbol, all get stripped off. no extra fluff, we love a clean parse. ✨

the available options include:

• default_ttl=<number> — the number of seconds to set as the expiration on a cached record. 🕐 this gets overridden if the program manages to retrieve TTL information along with the addresses (like, if it accesses the DNS directly, for example). the default is 5 seconds. the value must be in the range 1 to INT_MAX.

the file can also include comments beginning with a # character — unless that's otherwise suppressed by being inside a quoted value, or by being escaped with a backslash. 🎀

🎀 FILES 🎀

• /etc/key.dns_resolver.conf

lowkey reminder bestie: that 1 to INT_MAX range on default_ttl is not a suggestion, it's the vibe check. stay in range. 🫶
