The wiki says SOCKET_WRAPPER_PCAP_FILE can be used from *within* the testenv
shell. I guess that's still the case, but that's only for the commands
you execute within that shell.

That's only an internal helper variable.

SOCKET_WRAPPER_PCAP=1 and SOCKET_WRAPPER_KEEP_PCAP=1 are the controls for make test

I typically use this:

TDB_NO_FSYNC=1 make -j test FAIL_IMMEDIATELY=1 SOCKET_WRAPPER_KEEP_PCAP=1 TESTS='samba3.blackbox.smbclient.s3.SMB3.plain.member_creds.nt4_member'

Under the selftest prefix there's a 'w/pcap/' subdir, with files like these:

env-nt4_dc-nmbd.pcap   env-nt4_dc-smbd.pcap      env-nt4_member-setup.pcap  env-nt4_member-winbindd.pcap
env-nt4_dc-setup.pcap  env-nt4_member-nmbd.pcap  env-nt4_member-smbd.pcap
