### Version 2.16.0 ### Bug description Using a ChannelShell to manage the connection, anything written out to an SSH server (`ChannelShell.getInvertedIn()`) gets echoed back on the input stream (`ChannelShell.getInvertedOut()`). Connecting to the exact same servers with a jsch SSH implementation does not have any output echo, so its definitely not a server configuration problem. ### Actual behavior I've tried disabling all echo flags in the PtyMode: ``` HashMap<PtyMode, Integer> ptyModes = new HashMap<>(); ptyModes.put(PtyMode.ECHO, 0); ptyModes.put(PtyMode.ECHOE, 0); ptyModes.put(PtyMode.ECHOK, 0); ptyModes.put(PtyMode.ECHONL, 0); channel.setPtyModes(ptyModes); ``` Also tried disabling agent forwarding via `ChannelShell.setAgentForwarding(false)` (even though this function has no javadoc and I have no idea what it might actually do). At this point I can only surmise there's something else going on that needs to be examined to prevent output echo. ### Expected behavior Setting echo flags to 0 should disable output echo, or some other setting needs to be made available to generally stop output from being echoed back on the input stream. ### Relevant log output ```Shell ``` ### Other information _No response_ -- This is an automated message from the Apache Git Service.
