sounds similar to unsupported encryption schema that resolvable by compiling super-fresh libssh, cannot find issue, but AFAIR @singalen posted it (and resolved) some time ago

unxed commented 4 years ago

Stupid question, but: how to tell far2l prefix of custom openssh build?

elfmz commented 4 years ago

not openssh, but libssh try: cmake -DCMAKE_BUILD_TYPE=Release -DLIBSSH_LIBRARIES=/home/user/projects/libssh/libssh-0.9.0-build/lib/libssh.so -DLIBSSH_INCLUDE_DIRS=/home/user/projects/libssh/libssh-0.9.0/include ../far2l note that include dirs root differs from libs - it points to sources, while libs points to build results. Be careful with that include path - if you will specify wrong path - it will look into system's include directory and if you have libssh installed there - will use it instead of correct one.

unxed commented 4 years ago

Did

cmake -DCMAKE_BUILD_TYPE=Release -DLIBSSH_LIBRARIES=/home/unxed/far2l/test_libssh/far2l/libssh-0.9.2/build/lib/libssh.so -DLIBSSH_INCLUDE_DIRS=/home/unxed/far2l/test_libssh/far2l/libssh-0.9.2/include ../far2l

Still "key auth failed" :(

Did apt remove libssh-4 libssh-dev to verify that correct libssh version is used, repeated cmake & make.

Still the same error.

Custom libssh build is used for sure: if I rename the folder with it, sftp broker fails to start.

elfmz commented 4 years ago

ok, need logs from netrocks open terminal, type there: export FAR2L_STD=- export NETROCKS_VERBOSE=3 ..and finally run far2l (in GUI mode) from that terminal - it will write much debug logs

unxed commented 4 years ago

Oh, it was entirely my fault :) Closing :))
