Excessive WARN messages

[mherb63]

We are using this to send a bunch of commands to a Network Interface device. For every exec() command we get one of these WARN

15:34:59.554 [http-bio-8080-exec-7] WARN  com.jcabi.ssh.SSH - Permanently added '10.24.10.38' (RSA) to the list of known hosts.

here's how we're using the tool:

  Shell shell = new SSHByPassword("10.24.10.38", 22, "user", "password");
  for (commandList: command) {
    String output = new Shell.Plain(shell).exec(cmd);
  }

Is there something wrong with the way we are using this tool? Why are you trying to permanently add the IP address on each exec() I would assume that is done once when we new SSHByPassword

@yegor256 please, pay attention to this issue

Well it seems like the ChannelExec is re-established for each exec() we invoke. Is there any way you could provide a way to keep the channel open? Once we are done sending our exec()s we could close the channel ourselves.

@mherb63 it's not possible in current design. Each exec() works with its own connection/session. This is how it is designed. If you need something more fine-grained, use jSch directly.

@mherb63 also, you can get rid of that warning through ssh configuration file: https://stackoverflow.com/a/19733924/187141
