Hey everyone,

I could really use some advice from experienced Linux admins/engineers.

I'm currently working in IT, and due to company policies I can't disclose the company name. I've been deployed as a vendor resource, and from Monday I'll be working in an L2/L3 Linux support role.

The truth is, I don't have much real-world L2/L3 production experience, and I'm honestly a bit nervous. I don't want to fake it I genuinely want to learn and do a good job.

I'd really appreciate it if you could share:

• What does a typical day for an L2/L3 Linux engineer look like?
• What kind of tickets do you usually handle?
• How do you troubleshoot production issues without making things worse?
• How do you handle vulnerability remediation (Nessus, Qualys, OpenSCAP, etc.)?
• What Linux commands or concepts should I absolutely know before Monday?
• Any tips or mistakes to avoid for someone starting in production?

If you've ever been in this situation, I'd love to hear your experience. Any advice, checklists, YouTube channels, documentation, or even a DM would mean a lot.

I know there's no shortcut to experience, but I'm ready to learn, work hard, and improve every day.

Thanks in advance, and I really appreciate this community. 🙏

I somehow reached the office despite the rain.
