Reason

Solution

• Log in as a super/root user on the server.
• Edit the configuration file /opt/ssh/etc/sshd_config as shown below:

  # vi /opt/ssh/etc/sshd_config

  .
  .
  .
  #AllowAgentForwarding yes
  #AllowTcpForwarding yes
  #GatewayPorts no
  X11Forwarding yes
  #X11DisplayOffset 10
  #X11UseLocalhost yes
  #PrintMotd yes
  #PrintLastLog yes
  #TCPKeepAlive yes
  #UseLogin no
  #EnforceSecureTTY no
  #UsePrivilegeSeparation yes
  #PermitUserEnvironment no
  #Compression delayed
  #ClientAliveInterval 0
  #ClientAliveCountMax 3
  #UseDNS yes
  #PidFile /var/run/sshd.pid
  #MaxStartups 10
  #PermitTunnel no
  #ChrootDirectory none
  .
  .
  
  

• Change the #UseLogin no to UseDNS no and save the file.

  .
  .
  .
  #AllowAgentForwarding yes
  #AllowTcpForwarding yes
  #GatewayPorts no
  X11Forwarding yes
  #X11DisplayOffset 10
  #X11UseLocalhost yes
  #PrintMotd yes
  #PrintLastLog yes
  #TCPKeepAlive yes
  #UseLogin no
  #EnforceSecureTTY no
  #UsePrivilegeSeparation yes
  #PermitUserEnvironment no
  #Compression delayed
  #ClientAliveInterval 0
  #ClientAliveCountMax 3
  UseDNS no
  #PidFile /var/run/sshd.pid
  #MaxStartups 10
  #PermitTunnel no
  #ChrootDirectory none
  .
  .
  
  

• These changes will come into effect when the ssh service will be restarted. To restart the ssh service, use the below commands:

  # /sbin/init.d/secsh stop
  HP-UX Secure Shell stopped
  # /sbin/init.d/secsh start
  HP-UX Secure Shell started

Now login on to the server through PuTTY and you will be able to log in successfully without any delay.
