session.setEnvVar throws ConnectionError

[selimober]

I'm testing to connect to localhost. I manage to connect and execute a command without session.setEnvVar.

With session.setEnvVar enabled it throws:

net.schmizz.sshj.connection.ConnectionException: Request failed

The code is as follows:

    SSHClient ssh = new SSHClient();
    ssh.addHostKeyVerifier(new PromiscuousVerifier());
    ssh.connect("192.168.1.99"); //localhost
    TaskRunResponse response;
    try {
        ssh.authPassword("user", "pwd");
        Session session = ssh.startSession();
        try {
            session.setEnvVar("testenv", "123");
            Session.Command cmd = session.exec("/Users/selimober/tmp/paramandenvtest.sh 10");
            cmd.join();
            String output = IOUtils.readFully(cmd.getInputStream()).toString();
            Integer exitStatus = cmd.getExitStatus();
            response = new TaskRunResponse(ExitStatus.SUCCESS, output);
        } finally {
            session.close();
        }
    } finally {
        ssh.disconnect();
    }

I'm running into this issue as well. Currently in the thick of a deadline, but I'll try to help debug/fix this when I get some downtime here.

I too am running into this issue. Any idea of a temporary work-around?

I'm connecting to a CentOS 6.6 running OpenSSH 5.3p1 if this helps.

Which version of sshj?

I meant to say that too, sorry. It's version SSHJ 0.14.0.

However, I'm starting to think it's not a bug in SSHJ as I can't use Putty to set environmental variables on initial connection either. I'm going to look into this further.

Anyone found the solution for this?

[Tuchkata]

As far as I know the server should allow setting environment variables. For OpenSSH it should be set in /etc/sshd_config.

@hierynomus I am facing this issue in CentOs 7 with SSHJ version 0.31.0. Any alternative solution for this issue to set envVars while executing the command?
