10.3. Fixing Common Problems

10.3.1. LN Manager sees processes from another instance

instance name must be set to a unique name

10.3.2. LN Manager cannot start processes on other hosts

secure-shell setup needs to allow for password-less logins

10.3.3. LN Manager cannot connect to daemon, error message about wrong DSA keys for daemon

might need to delete and re-generate keys?

10.3.4. Cannot import links_and_nodes python module

is the PYTHONPATH correctly set?
are you running the right Python version?
possibly you need to use the excevpe process flag? (explain when to use it)

10.3.5. LN Manager cannot start process

possibly path name wrong
might use relative path but the CWD is not set

10.3.5.1. Topic names with trailing slashes

work sometimes (in python, but not always)

10.3.5.2. Conan environment for CPP Builds

One needs to define the environment as follows:

conan install links_and_nodes_manager/[~2]@common/stable -if conan -g virtualenv -g virtualenv_python -g virtualrunenv -g virtualbuildenv

Here, you should replace links_and_nodes_manager/[~2]@common/stable by the current LN version, which is links_and_nodes_manager/[~2.6]@common/stable.
