Q: sessionctx_sniffer.py does not seem to dissect large SSL/TLS records properly.Ī: In order to fully reconstruct sniffed SSL/TLS records one needs to defragment the sniffed IP packets and reassemble them to TCP segments. Note: This has been addressed with >=v1.2.3 where the system-wide import has preference. Make sure to update to >=v1.2.3, or run sessionctx_sniffer.py from a different directory, or uninstall scapy-ssl_tls to use it directly from the project directory, or remove the from scapy_ssl_tls.ssl_tls import * import lines from the example. Q: sessionctx_sniffer.py does not seem to detect SSL/TLS or does not show any sniffed SSL/TLS sessions.Ī: This is problem caused by the import magic in sessionctx_sniffer.py where the example might mix up imports from the projects directory with the ones installed with pip or via setup.py install. ssl_tls import TLS > TLS #> scapy # with layers autoloaded via config.py > SSL > TLS > TLSRecord Troubleshooting ssl_tls import TLS > TLS #> scapy # via site-packages > from scapy_ssl_tls. Installation Option 1: pip - download latest release from the python package index 🐍 Note: an experimental python 3 compat mode is available on the p圓compat branch and is planned to be merged into master once fully tested (see issue #39). support with scapy before v2.4 is broken due to major changes in scapy. ✔️ maintenance: only bug-fixes will be released ✔️ not fully backwards compatible with v1.x due to interface changes ⚠️
