TRY-FROM(8)

💖 TRY-FROM(8) 💖

okay bestie, welcome to the try-from manual page — it lives in the Linux Programmer's Manual section 8, and it's about to be your new fave little detective tool. 🕵️‍♀️✨

---

🌸 NAME 🌸

try-from — it's a test program for the tcp_wrapper, no cap. that's literally its whole job and it does it flawlessly. 💅

---

✨ SYNOPSIS ✨

try-from

that's it. that's the whole thing. no flags, no arguments, she's low maintenance and highkey iconic. 👑

---

🎀 DESCRIPTION 🎀

so here's the vibe, bestie: you call try-from via a remote shell command, and it goes and figures out three little things for you, like a tiny gossipy messenger: 💌

• whether the hostname and address are properly recognized by the tcp_wrapper library 🦋
• whether username lookup actually works 🔍
• and — SysV only, so don't come for me if you're on something else — whether the TLI on top of IP heuristics work 🧚

all the diagnostics get reported through syslog(3) and redirected to stderr, so you'll get the tea from both directions fr fr. 😭💖

🍓 Example 🍓

rsh host /usr/sbin/try-from

run it, read the diagnostics, slay. that's the whole ritual. ✨

🌈 SEE ALSO 🌈

• hosts_access(5)
• hosts_options(5)
• tcpd(8)

go read those too, they're giving main character energy and they're basically the rest of the lore. 📚💜
