Cannot connect even locally - Failed a call to readAll: Broken pipe

Open miker985 opened this issue 1 year ago • 3 comments

I'm experiencing failures connecting to etserver on localhost. ssh localhost works

I see that after et localhost is run but before I actually respond to the password prompt things already appear to be broken

Here's the etserver log output

miker985@miker985-x1:~$ etserver -p 2022 -v 9 --logtostdout

Removing ~/.ssh changes nothing except prompting to confirm the key fingerprint.

ET is built from scratch as of a few minutes prior to this issue post with the following script. In a former life I ran a lot of software out of my user account at ~/usr but on this machine there is only 1 other piece of software: bitlbee and I do not think it is having any sort of impact.

What is the path to etterminal? /usr/bin/etterminal? I'm guessing you need to pass the path prefix as the default isn't finding etterminal hence the error:

auto passKeyIndex = sshBuffer.find(string("IDPASSKEY:"));
    if (passKeyIndex == string::npos) {
      // Returned value not contain "IDPASSKEY:"
      CLOG(INFO, "stdout")
          << "Error in authentication with etserver: " << sshBuffer
          << ", please make sure you don't print anything in server's "
             ".bashrc/.zshrc"
          << endl;
      exit(1);
    }

Try running: et -v9 --logtostdout --terminal-path=/usr/bin/etterminal localhost

What is the path to etterminal?

Both bash sessions (the one running etserver and et) have etterminal on their PATH

miker985@miker985-x1:~$ which etterminal
/home/miker985/usr/bin/etterminal

Try running: et -v9 --logtostdout --terminal-path=/usr/bin/etterminal localhost

etserver

miker985@miker985-x1:~/bin$ etserver  --logtostdout -v9

EDIT: I tried manually linking etterminal to /usr/bin and get the same error

Can you print/log sshBuffer from here https://github.com/MisterTea/EternalTerminal/blob/master/src/terminal/SshSetupHandler.cpp#LL75C9-L75C9 to see what it is returning. Also do you have any errors in your etterminal log file (server side)?
