Tor with Shadow

[suriasarath]

I am new to Shadow. Previously, I'm currently attempting to run Tor with Shadow, but I'm encountering the following issue. Could you please help me fix it?

The following error I received from shadow.log.

How did you generate the Shadow configuration? With tornettools? Or is this from an example?

The tor and tor-gencert processes are exiting with a non-zero exit code indicating that they had an error. Can you post the stdout/stderr logs for one of the failed processes? For example: shadow.data/hosts/relay1/tor.1000.stdout and shadow.data/hosts/relay1/tor.1000.stderr.

Can you also post the output of tor --version?

Thanks for the replay. Tor version is 4.7.13, I am using shadow configuration from example.

If you still want help, we'll need details from the log files. As requested by @stevenengler, you should post the stdout/stderr logs for one of the failed processes. For example, you should post the contents of:

• shadow.data/hosts/relay1/tor.1000.stdout and
• shadow.data/hosts/relay1/tor.1000.stderr.
