🌸 NAME 🌸

okay so bestie, locktest — it finds differences in locking between two SMB servers. that's the whole assignment. 💅

(also hi, this is LOCKTEST(1) from the Test Suite section of the manual, so you're in the right place 🫶)

🦋 SYNOPSIS 🦋

locktest {//server1/share1} {//server2/share2} [-U user%pass]
         [-U user%pass] [-s seed] [-o numops] [-a] [-O] [-E] [-Z]
         [-R range] [-B base] [-M min]

✨ DESCRIPTION ✨

locktest is that utility for detecting differences in behaviour in locking between SMB servers. like, it's a whole detective 🔍

here's the tea: it runs a random set of locking operations against //server1/share1, and then runs the exact same random set against //server2/share2, and then it shows you the differences in the responses it gets. side by side, no cap. 😭

and who uses this? the Samba team does — they use this utility to find differences in behaviour between Samba and Windows servers. iconique behaviour tbh 👑

💅 OPTIONS 💅

  • -U user%pass — tell it the user and password to use when logging on on the shares. and listen, you can specify this parameter twice — once for the first server, once for the second. one for you, one for your bestie 🫶
  • -s seed — seed the random number generator with the specified value. so your chaos is at least reproducible chaos ✨
  • -o numops — set the number of operations to perform.
  • -a — print the operations that are performed. so you actually see what it's doing 👀
  • -A — backtrack to find minimal number of operations required to make the response to a certain call differ. it's giving minimalism, it's giving forensics 💀
  • -O — enable oplocks.
  • -u — hide unlock fails. shhh. 🙈
  • -E — enable exact error code checking. be precise, bestie.
  • -Z — enable the zero/zero lock.
  • -R range — set lock range.
  • -B base — set lock base.
  • -M min — set min lock length.
  • -k — use kerberos.

🌈 VERSION 🌈
