Unable to use with Bastion Server (err255) #153
Description
the bastion server in question is (sshPortal)[https://github.com/moul/sshportal]
something in this chunk of code in sshcode.go
errors out with Error Code 255
Dont know exactly what is causing it, but my therory is it is trying to do things on the bastionserver before it is proxied across to the target,
To reproduce, do the following
install sshportal
"invite" a new user, and add a host,
create invite <email, can be false>
# read the readme of the program for how to do so
host create user@host:port --name <hostname, can be anything>
then ssh through sshportal to the host, to verify it is configured properly
ssh <hostname>@portal -p 2222
Then test sshcode to verify this issue
sshcode --skipsync --ssh-flags "-p 2222" <hostname>@portal
If you are unable to reproduce this issue, go ahead and close this
if o.uploadCodeServer != "" {
flog.Info("uploading local code-server binary...")
err = copyCodeServerBinary(o.sshFlags, host, o.uploadCodeServer, codeServerPath)
if err != nil {
return xerrors.Errorf("failed to upload local code-server binary to remote server: %w", err)
}
sshCmdStr :=
fmt.Sprintf("ssh %v %v 'chmod +x %v'",
o.sshFlags, host, codeServerPath,

sshCmd := exec.Command("sh", "-l", "-c", sshCmdStr)
sshCmd.Stdout = os.Stdout

err,

}
} else {

dlScript := downloadScript(codeServerPath)
// Downloads the latest code-server and allows it to be executed.
sshCmdStr := fmt.Sprintf("ssh %v %v '/usr/bin/env bash -l'", o.sshFlags, host)

@Merith-TK please post logs from sshcode.
