I am porting over the portable version of openssh to our uCLinux implementation. Everything has worked with minimal effort and I appreciate all the work. But, I am having a problem whereby the sshd executable is crashing and I really could use some help on where to look at this in more details. Here is how I start up the sshd for testing. /usr/sbin/sshd -D -ddd -f /etc/ssh/sshd_config -p 65 Then I connect to it with the folloiwng command sshd -vvv admin@<ip addr> -p 65 It connects with no problem. But, when I hit the return key I get a big fat error.. I've attached the debug output at the end of this email. Any advice on where to start debugging this is most appreciated. Thanks. -brad w. /bin # /usr/sbin/sshd -D -ddd -f /etc/ssh/sshd_config -p 65 debug2: load_server_config: filename /etc/ssh/sshd_config debug2: load_server_config: done config len = 852 debug2: parse_server_config: config /etc/ssh/sshd_config len 852 debug3: /etc/ssh/sshd_config:18 setting AddressFamily inet debug3: /etc/ssh/sshd_config:21 setting ListenAddress 192.168.0.2 debug3: /etc/ssh/sshd_config:27 setting HostKey /etc/ssh/ssh_host_key debug3: /etc/ssh/sshd_config:29 setting HostKey /etc/ssh/ssh_host_rsa_key debug3: /etc/ssh/sshd_config:30 setting HostKey /etc/ssh/ssh_host_dsa_key debug3: /etc/ssh/sshd_config:34 setting KeyRegenerationInterval 1h debug3: /etc/ssh/sshd_config:35 setting ServerKeyBits 1024 debug3: /etc/ssh/sshd_config:43 setting SyslogFacility AUTHPRIV debug3: /etc/ssh/sshd_config:54 setting RSAAuthentication yes debug3: /etc/ssh/sshd_config:55 setting PubkeyAuthentication yes debug3: /etc/ssh/sshd_config:72 setting IgnoreUserKnownHosts yes debug3: /etc/ssh/sshd_config:74 setting IgnoreRhosts yes debug3: /etc/ssh/sshd_config:77 setting PasswordAuthentication yes debug3: /etc/ssh/sshd_config:78 setting PermitEmptyPasswords yes debug3: /etc/ssh/sshd_config:79 setting PasswordAuthentication yes debug3: /etc/ssh/sshd_config:83 setting ChallengeResponseAuthentication no debug3: /etc/ssh/sshd_config:111 setting UsePAM no /etc/ssh/sshd_config line 111: Unsupported option UsePAM debug3: /etc/ssh/sshd_config:116 setting X11Forwarding no debug3: /etc/ssh/sshd_config:129 setting UseDNS no debug3: /etc/ssh/sshd_config:140 setting AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES debug3: /etc/ssh/sshd_config:141 setting AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT debug3: /etc/ssh/sshd_config:142 setting AcceptEnv LC_IDENTIFICATION LC_ALL LANGUAGE debug3: /etc/ssh/sshd_config:143 setting AcceptEnv XMODIFIERS debug3: /etc/ssh/sshd_config:146 setting Subsystem sftp /usr/local/libexec/sftp-server debug1: sshd version OpenSSH_6.7, OpenSSL 1.0.1g 7 Apr 2014 debug1: private host key: #0 type 0 RSA1 debug3: Incorrect RSA1 identifier debug1: key_parse_private2: missing begin marker debug1: read PEM private key done: type RSA debug3: Incorrect RSA1 identifier debug3: Could not load "/etc/ssh/ssh_host_rsa_key" as a RSA1 public key debug1: private host key: #1 type 1 RSA debug3: Incorrect RSA1 identifier debug1: key_parse_private2: missing begin marker debug1: read PEM private key done: type DSA debug3: Incorrect RSA1 identifier debug3: Could not load "/etc/ssh/ssh_host_dsa_key" as a RSA1 public key debug1: private host key: #2 type 2 DSA debug1: rexec_argv[0]='/usr/sbin/sshd' debug1: rexec_argv[1]='-D' debug1: rexec_argv[2]='-ddd' debug1: rexec_argv[3]='-f' debug1: rexec_argv[4]='/etc/ssh/sshd_config' debug1: rexec_argv[5]='-p' debug1: rexec_argv[6]='65' debug2: fd 4 setting O_NONBLOCK debug1: Bind to port 65 on 192.168.0.2.
