SSH session not properly closed by Karaf
Hi,
After using < client > script, the tcp socket is not closed by karaf (4.3.2) and remains in CLOSE_WAIT state. The session is only closed after ssh timeout is reached.
For instance with a SSH timeout set to 30 s :
$ ./client "bundle:list"
$ netstat | grep 8101
tcp6 0 0 localhost:8101 localhost:47844 CLOSE_WAIT
$ tail karaf.log
INFO | sshd-SshServer[2f716f77](port=8101)-nio2-thread-1 | ServerSessionImpl | 46 - org.apache.sshd.osgi - 2.5.1 | Session karaf@/127.0.0.1:47844 authenticated
INFO | sshd-SshServer[2f716f77](port=8101)-timer-thread-1 | ServerSessionImpl | 46 - org.apache.sshd.osgi - 2.5.1 | Disconnecting(ServerSessionImpl[karaf@/127.0.0.1:47844]): SSH2_DISCONNECT_PROTOCOL_ERROR - Detected IdleTimeout after 30415/30000 ms.
Do you have a fix for this issue ?

Hi,
I guess the connexion is cleanly closed when you do:
$ bin/client
And then CTRL-D
Right ?
