Hi, sorry if I've sent this to the wrong list. I'm having a strange issue where establishing an SSH connection to an AIX box running openssh v4.6 pauses for approximately 30 seconds during the connection process (I have UseDNS set to no). >From the client: --- dgreen49@linuxhost1 [~]# ssh -vvv aixhost1 OpenSSH_4.3p2-hpn, OpenSSL 0.9.7a Feb 19 2003 debug1: Reading configuration data /opt/soe/local/etc/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to 10.44.138.107 [10.44.138.107] port 22. debug1: Connection established. debug1: identity file /home/dgreen49/.ssh/identity type -1 debug1: identity file /home/dgreen49/.ssh/id_rsa type -1 debug1: identity file /home/dgreen49/.ssh/id_dsa type -1 <pauses here> debug1: Remote protocol version 2.0, remote software version OpenSSH_4.6p1-hpn12v17 debug1: match: OpenSSH_4.6p1-hpn12v17 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.3p2-hpn debug2: fd 3 setting O_NONBLOCK [...] --- >From the server: --- root@aixhost1 [~]# /opt/soe/local/openssh/sbin/sshd -ddd [...] debug1: rexec_argv[0]='/opt/soe/local/openssh/sbin/sshd' debug1: rexec_argv[1]='-ddd' debug2: fd 3 setting O_NONBLOCK debug1: Bind to port 22 on 0.0.0.0. debug1: Server TCP RWIN socket size: 65536 debug1: HPN Buffer Size: 131072 Server listening on 0.0.0.0 port 22. debug1: fd 4 clearing O_NONBLOCK debug1: Server will not fork when running in debugging mode. debug3: send_rexec_state: entering fd = 7 config len 1421 debug3: ssh_msg_send: type 0 debug3: send_rexec_state: done debug1: rexec start in 4 out 4 newsock 4 pipe -1 sock 7 <pauses here> debug1: inetd sockets after dupping: 3, 3 Connection from linuxhost1 port 1119 [...] --- sshd_config on AIX host: --- AllowTcpForwarding yes Banner /etc/issue ChallengeResponseAuthentication yes ClientAliveInterval 0 ClientAliveCountMax 3 Compression yes GatewayPorts no HostbasedAuthentication no IgnoreRhosts yes IgnoreUserKnownHosts no KeyRegenerationInterval 1h Port 22 ListenAddress 0.0.0.0 LoginGraceTime 2m LogLevel INFO MaxAuthTries 10 MaxStartups 10 PasswordAuthentication yes PermitEmptyPasswords no PermitRootLogin no PermitUserEnvironment no PidFile /var/run/sshd.pid PrintLastLog yes PrintMotd yes Protocol 2 PubkeyAuthentication yes RhostsRSAAuthentication no ServerKeyBits 768 StrictModes yes Subsystem sftp /opt/soe/local/openssh/libexec/sftp-server SyslogFacility AUTH TCPKeepAlive yes UseDNS no UseLogin no UsePrivilegeSeparation yes X11DisplayOffset 10 X11Forwarding yes X11UseLocalhost yes XAuthLocation /usr/bin/X11/xauth NoneEnabled no HPNDisabled yes --- Has anyone seen this before?
