Caught Signal 11 for process: 1234

[Eric Dykstra]

Hello again everyone,

I am using the SSH2 functionality in SilkJS to connect to a remote server.

It seems that no matter what command I pass to ssh.exec(), the ssh.response(con) always returns:

        Caught Signal 11 for process: 1234     (Where 1234 = PID)

I've tested with a command to simply 'touch /path/to/some/file' and that works as expected, but I still get the above error.

This doesn't help me debug commands with many more possible failure modes on the remote server, like 'git pull'. But, in trying to work-around this, I redirected the 'git pull' output to a file on the remote server using the command 'git pull > logfile.txt'. While it does create the file, it is empty. So - still no luck moving forward.

When I Google on the above error, I only get hits related to SilkJS, but none seem to help.

Thoughts?

Thanks in advance.

Just to close this out for anyone else coming here ....

Offline, Mike walked me through the solution. Short answer ... I was using the builtin/ssh when I should have been using the module.

Thanks Mike!

To clarify…

The builtin functions are really meant to be wrapped with a proper JavaScript class written in JavaScript.  The builtins are super low-level sorts of things.

In the spirit of "C" style programming, if you pass garbage (like a bad file descriptor) to a builtin function (like read or write), it will segfault or Signal 11.

The error checking of parameters is supposed to be done in the JavaScript code, not the C++ code.

If you find the classes I wrote and provide are insufficient for your needs, feel free to write your own.  The last thing I wanted to do was force anyone into some paradigm that doesn't fit the way they want to code.
