Jean-Baptiste Onofré commented on KARAF-5473:
---------------------------------------------
Enabling the keep alive on OpenSSH client seems to work. Especially, on sshd
side, I can see:
{code}
14:14:58.222 DEBUG [sshd-SshServer[892cb82]-nio2-thread-2]
sendResponse(ChannelSession[id=0,
recipient=0]-ServerSessionImpl[karaf@/127.0.0.1:44282]) request=window-change
result=ReplySuccess, want-reply=false
14:14:58.223 DEBUG [sshd-SshServer[892cb82]-nio2-thread-2]
sendResponse(ChannelSession[id=0,
recipient=0]-ServerSessionImpl[karaf@/127.0.0.1:44282]) request=window-change
mismatched channel type: shell
{code}
I'm testing adding keep alive on the Karaf client.
