Hello, I have a problem with the OpenSsh services which fails, but I don't find the reasons of these regular failuresI need help for reading the logs inserted below I have several SSH connexions between :- a File Server in which the Ssh server based on OpenSsh 6.6.1p1-3(Windows 2008 SP2 64bits) has been installed,- a Ssh client OpenSsh 4.3P2, installed on a SANTOS Linux distribution, - others Ssh clients based on OpenSsh 6.2p2-1(Windows 2008 SP2 64bits) Note : The problem was also present with the version setupssh-6.2p2-1-v1.exe, which have been firstly installed on my File server my configuration is based on RSA authentification (sshd_config attached) I have also changed the following parameters, but without any successLoginGraceTimeThe server disconnects after this time if the user hasnotsuccessfully logged in. If the value is 0, there is no time limit.Thedefault is 600 (seconds).LoginGraceTime 30 KeepAliveSpecifies whether the system should send keepalive messages to theotherside. If they are sent, death of the connection or crash of oneof the machineswill be properly noticed. However, this means thatconnections will die if theroute is down temporarily, and some peoplefind it annoying. On the other hand,if keepalives are not send,sessions may hang indefinitely on the server,leaving "ghost" usersand consuming server resources. he default is"yes" (to send keepalives), and the server will noticeif the networkgoes down or the client host reboots. This avoidsinfinitely hangingsessions.KeepAlive yes ClientAliveCountMax – This indicates the total number of checkalive message sent by the sshserver without getting any response from the ssh client. Default is 3.ClientAliveCountMax 0 · ClientAliveInterval – This indicates the timeout in seconds. After x numberof seconds, ssh server will send a message to the client asking for response.Deafult is 0 (server will not send message to client to check.).ClientAliveInterval10 It's seems it's the linux client (IP : 192.168.32.30 ) which provokes the failure of the OpenSsh service on my File Server? In my EventViewer, I have the logs : (PRESENT) sshd: PID 5236: debug1: attempt 1 failures 0 sshd: PID 5236: debug2: input_userauth_request: try method publickey sshd: PID 5236: debug3: userauth_finish: failure partial=0 next methods="publickey,password,keyboard-interactive sshd: PID 5236: debug1: userauth_send_banner: sent sshd: PID 5236: debug2: input_userauth_request: try method none sshd: PID 5236: debug1: userauth-request for user operateur service ssh-connection method publickey sshd: PID 5236: debug1: test whether pkalg/pkblob are acceptable sshd: PID 5236: debug1: temporarily_use_uid: 1000/513 (e=500/513) sshd: PID 4604: debug3: session_unused: session id 0 unused sshd: PID 4604: debug1: do_cleanup sshd: PID 4604: debug3: channel 0: status: The following connections are open:\r\n #0 server-session (t4 r619955 i3/0 o3/0 fd -1/-1 cc -1)\r\n sshd: PID 4604: debug1: session_close: session 0 pid 3864 sshd: PID 4604: Transferred: sent 5328, received 687736 bytes sshd: PID 5236: debug2: parse_server_config: config reprocess config len 442 sshd: PID 5236: debug2: input_userauth_request: setting up authctxt for operateur sshd: PID 4604: Closing connection to 10.101.8.2 port 2388 OpenSSHd: PID 2340: service `OpenSSHd' failed: signal 11 raised sshd: PID 5248: debug2: channel 0: close_read sshd: PID 5248: debug2: channel 0: input open -> drain sshd: PID 5248: debug2: channel 0: read failed sshd: PID 5248: debug2: notify_done: reading sshd: PID 5248: debug2: channel 0: read<=0 rfd 8 len 0 sshd: PID 5248: debug2: channel 0: ibuf empty sshd: PID 5248: debug3: channel 0: will not send data after close sshd: PID 5248: debug2: channel 0: rcvd close sshd: PID 5248: debug2: channel 0: send close sshd: PID 5248: debug2: channel 0: send eof sshd: PID 5248: debug2: channel 0: input drain -> closed sshd: PID 5248: debug2: channel 0: request exit-status confirm 0 sshd: PID 5248: debug1: session_exit_message: release channel 0 sshd: PID 5248: debug1: session_exit_message: session 0 channel 0 pid 3080 sshd: PID 5248: debug1: Received SIGCHLD. sshd: PID 5248: debug1: session_by_pid: pid 3080 sshd: PID 5248: debug2: channel 0: write failed sshd: PID 5248: debug2: channel 0: read 0 from efd 10 sshd: PID 5248: debug2: channel 0: closing read-efd 10 sshd: PID 5248: debug2: channel 0: output open -> closed sshd: PID 5248: debug2: channel 0: close_write sshd: PID 5248: debug2: channel 0: send eow sshd: PID 5248: Transferred: sent 430056, received 2368 bytes sshd: PID 5248: Closing connection to 192.168.32.30 port 56963 sshd: PID 5248: debug1: do_cleanup sshd: PID 5248: debug3: channel 0: status: The following connections are open:\r\n #0 server-session (t4 r0 i3/0 o3/0 fd -1/-1 cc -1)\r\n sshd: PID 5248: Connection closed by 192.168.32.30 sshd: PID 4604: debug2: channel 0: window 1998376 sent adjust 98776 sshd: PID 4604: debug2: channel 0: window 1966472 sent adjust 130680 sshd: PID 4604: debug2: channel 0: rcvd close sshd: PID 4604: debug2: channel 0: window 1966472 sent adjust 98010 sshd: PID 4604: debug2: channel 0: window 1966472 sent adjust 130680(PAST) regardsEmmanuel _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
