Network + TLS diagnostics

v0.1.3

DNS lookups, reachability probes, TLS certificate inspection, and HTTP timing tests. All read-only. Use for "is X reachable?" and "what's the cert expiry on Y?" questions.

Pack ID

network-tls

Vendor

emisar

linux

Actions

Required binaries: curl, dig, mtr, openssl, ping, whois. Actions that call a missing binary fail at run time — install these on the host before relying on the pack.

Install

emisar pack install validates the pack and verifies its content hash before copying it into /etc/emisar/packs. The --hash below pins the install to the exact bytes on this page — a tampered copy is rejected. After install, reload the runner; it re-reads the catalog and advertises every action.

content hash: sha256:cb665e25affd9774adcc17dd37ff29dff10148b18750fd8449988288d483fa67

on the runner host

sudo emisar pack install network-tls \
  --hash sha256:cb665e25affd9774adcc17dd37ff29dff10148b18750fd8449988288d483fa67 \
  --dest /etc/emisar/packs

# Reload so the runner re-reads the catalog:
sudo systemctl reload emisar
