Hi all, I noticed a change in SSH server session close behavior, as I
upgraded from 4.3.10 to 4.4.5.
Doing calls such as
ssh -p 8101 karaf@localhost feature:list
still works fine. However with 4.4.5, the ssh client now sporadically
reports
Connection to localhost closed by remote host.
The difference seems in the session shutdown.
In the "good" case it is:
debug2: channel 0: rcvd eof
debug2: channel 0: output open -> drain
debug2: channel 0: obuf empty
debug2: channel 0: chan_shutdown_write (i0 o1 sock -1 wfd 5 efd 6 [write])
debug2: channel 0: output drain -> closed
debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
debug2: channel 0: rcvd close
debug2: channel 0: chan_shutdown_read (i0 o3 sock -1 wfd 4 efd 6 [write])
debug2: channel 0: input open -> closed
debug2: channel 0: almost dead
debug2: channel 0: gc: notify user
debug2: channel 0: gc: user detached
debug2: channel 0: send close
debug2: channel 0: is dead
debug2: channel 0: garbage collecting
debug1: channel 0: free: client-session, nchannels 1
Transferred: sent 2064, received 28800 bytes, in 0.1 seconds
Bytes per second: sent 23511.4, received 328065.6
debug1: Exit status 0
In the "bad" case it is:
debug2: channel 0: rcvd eof
debug2: channel 0: output open -> drain
debug2: channel 0: obuf empty
debug2: channel 0: chan_shutdown_write (i0 o1 sock -1 wfd 5 efd 6 [write])
debug2: channel 0: output drain -> closed
debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
debug1: channel 0: free: client-session, nchannels 1
Connection to localhost closed by remote host.
Transferred: sent 2048, received 28768 bytes, in 0.0 seconds
Bytes per second: sent 41302.3, received 580168.6
debug1: Exit status 0
Seems a timing issue, interacting with the new SSHD code?
