Net::Op...STracer(3)

🌸 NAME 🌸

okay so welcome to Net::Op...STracer(3), bestie — this is from the User Contributed Perl Documentation, and it's the manual page for Net::OpenSSH::OSTracer: trace the master ssh process at the OS level. Like, literally at the operating-system layer. 💅

✨ SYNOPSIS ✨

vibe check: here's the synopsis, bestie:

use Net::OpenSSH;
$Net::OpenSSH::debug |= 512;

Net::OpenSSH->new($host)->system("echo hello world");

system "less /tmp/net_openssh_master.*.strace";

💅 DESCRIPTION 💅

This is a helper module for Net::OpenSSH that lets you trace the master ssh process at the operating system level, using the proper utility that's actually available on your system (for example strace, truss, ktruss, tusc, etc.). iconic. 🦋

Use it when you're debugging your programs or when you want to report bugs on the module. 🐛✨ main character debugging energy.

It's enabled by setting flag 512 on the $Net::OpenSSH::debug variable:

$Net::OpenSSH::debug |= 512;

By default, the tracer's output files are saved as /tmp/net_openssh_master.$pid.$tracer_type.

Also, the output that the tracer sends to stdout/stderr is saved as /tmp/net_openssh_master.$pid.txt.

🎀 The global variables (config girlies, iykyk) 🎀

The module can be configured through the following global variables:

• $Net::OpenSSH::OSTracer::type — By default, the module decides which tracer to use based on the operating system name. This variable lets you select a different tracer. Currently accepted types are: strace (Linux), ktrace (*BSD), tusc (HP-UX) and truss (Solaris and AIX). periodt.
• $Net::OpenSSH::OSTracer::cmd — Command to execute for tracing the ssh process. By default, it infers it from the selected tracer type.
• $Net::OpenSSH::OSTracer::output — Basename for the destination file. The PID of the ssh process and the tracer type will be appended.
• $Net::OpenSSH::OSTracer::sudo — This variable can be used to request the tracer to be run with sudo (some operating systems, for example Ubuntu, do not allow one to attach tracers, even to your own processes, unless you do it as root). The variable has to be set with the path of the sudo binary. For instance: $Net::OpenSSH::OSTracer::sudo = '/usr/bin/sudo';

If you need to pass a password to sudo, set the environment variable SUDO_ASKPASS. For instance: SUDO_ASKPASS=/usr/bin/ssh-askpass

• $Net::OpenSSH::OSTracer::delay — This variable can be used to delay the ssh execution so that the tracer can attach the process first. This is especially handy when using sudo with a password.

🫶 BUGS 🫶

highkey, this module has not been tested under all the operating systems it says to support. 😭 ngl, fr fr.
