- move the analysis server out of simtrace2_pysniff into simtrace_analyser;
simtrace2_pysniff stays as the simtrace2-sniff replacement capture utility
- new server CLI: simtrace-analyser-server; python -m simtrace_analyser
(simtrace2-pysniff-server and python -m simtrace2_pysniff.server dropped)
- simtrace2_pysniff lazy-imports hardware symbols, so the server no longer
pulls PyUSB at startup; the GSMTAP/PCAP codecs work without libusb
- version 2.0.0 everywhere (was 1.22.21); PWA SW cache simtrace-analyser-v54
- frontend: server name, clone URL and i18n strings updated; vendored-parser
reference otaman -> SIMple
- README/README_RUS reworked product-first (analyser first, utility second)
- DB dir ~/.simtrace-analyser, /api status payload and hosted PWA unchanged
pcap.py: LINKTYPE_GSMTAP (155) was wrong — 155 is DLT_USER8, so
Wireshark showed 'USER 8 / DLT=155'. Now write Ethernet-encapsulated
PCAP (LINKTYPE 1): each GSMTAP message wrapped in Ethernet + IPv4 +
UDP (port 4729), with correct checksums — matching a real tcpdump
capture of GSMTAP-over-UDP and how Wireshark's gsmtap dissector is keyed.
gsmtap.py: GSMTAP_TYPE_SIM was 0x07 (WiMAX burst) — corrected to 0x04;
GSMTAP_SIM_APDU was 0x02 (PPS req) — corrected to 0x00; added PPS_REQ/
PPS_RSP. These match libosmocore/Wireshark packet-gsmtap.h.
Verified with tshark: PCAP now decodes as GSM SIM (SELECT/STATUS/ATR)
instead of 'USER 8'.
tests: pcap tests assert Ethernet linktype + framing + GSMTAP payload.
pcap.py: build_pcap(packets) — build PCAP bytes in memory (same format
as PcapWriter)
database.py: get_messages_raw() — raw elapsed/type/data without decode
server.py: GET /api/sessions/<id>/pcap generates a GSMTAP-encapsulated
PCAP (ATR/TPDU) with real timestamps and downloads it as
<session-name>.pcap (ASCII filename fallback + RFC 5987 UTF-8 for
spaces/unicode via _content_disposition)
tests: build_pcap + _content_disposition (67 total)
