Show HN: nfsdiag - a NFS diagnostic application

A tiny new tool called nfsdiag just landed on Show HN, and the reaction was less “neat utility” and more group therapy for traumatized system admins. The app is basically a client-side detective for shared network drives: point it at a server, and it checks the usual chaos zones like connectivity, permissions, missing services, file locks, stale file errors, and whether the server is secretly treating users differently than expected. In plain English: it helps answer the cursed office question, “Why is the shared folder broken this time?”

The strongest reaction by far was pure relief. One commenter basically said this tool would have saved them at a past job, which is Hacker News code for “I have battle scars and receipts.” Another called it a “very powerful little helper,” giving the project the kind of approving nod that usually means, “finally, someone built the obvious thing nobody wants to build.” And then came the most emotionally charged hot take: debugging Kerberos login issues — the extra security layer often used in corporate setups — is, in one commenter’s words, a total nightmare. That line carried the thread’s biggest laugh, because everyone who’s touched old-school file sharing knows that pain is deeply, tragically real.

There wasn’t much outright fighting in the comments, but the drama came from the shared mood: NFS is the villain, this tool is the medic, and the commenters are survivors swapping war stories. The vibe was part applause, part flashback, and part “where was this when my weekend got ruined?”
