Hello, A known problem with hydra 5.4 is that it only compiles with libssh 0.11. this patch [1] applied to hydra lets it compile with libssh 0.2 and higher (the next release will be out in a few weeks). Regards, Aris [1] : http://0xbadc0de.be/libssh/hydra-libssh0.2.patch
Thank you for report, Aris. Patch was added in hydra-5.4-r2.
