Hi @meotimdihia,

Is the ssh program able to parse the file? Any chance your known_hosts file was generated or edited by a windows program?

I did some basic tests in a win10, using git bash and mole is working fine.

I still ssh to my server with this file for years. It seems Mole has more problems with known_host files. I tried to delete lines in known_hosts (in Vim) and get a new bug: known_hosts:30: knownhosts: missing host pattern"

edit: I fixed it by deleted the problem lines.

And I have a question, can Mole replace autossh? I can't install autossh on windows. I always use this command to tunnel my server and connecting to my Postgres database: ssh -nNT -L5432:localhost:5432 myserver

It will be hard trying to fix this issue without having the specific line that is creating the trouble. Would you mind posting it here?

That is probably happening because mole is not capable of generating an entry in your knownhosts file when you connect to the ssh server.

Mole has an auto connection restart mechanism through the --connection-retries flag.
It also sends synthetic packets to the server that acts as a keep-alive mechanism, through the --keep-alive-interval flag.

Sorry, I deleted those lines with no backup 😃.
I read the documentation and can't figure how to replace the command ssh -nNT -L5432:localhost:5432 myserver with mole.
Can you give me an example, thanks?

That's all right. I am closing the issue since this is not reproducable. Feel free to re-open it if you see a need.

mole start local --source :5432 --destination 127.0.0.1:5432 --server myserver

Since myserver is not a domain or ip address, it will look for its entry on your ssh config file.
