SSH Authentification very slow on HPUX

Two steps:

1>  Check DNS :
  • check  /etc/resolv.conf
  • check /etc/nsswitch.conf (hosts and also ipnodes should have files...dns.. entry)
  • check /etc/hosts (FQDN & short host name)
2> Purge  /var/adm/wtmp and /var/adm/wtmps
  • cd /var/adm
  • rm wtmps wtmp
  • touch wtmps wtmp
  • chmod 664 wtmps wtmp
  • chown adm:adm wtmps wtmp
If those steps did not help; then check following :

  1. network to make the speed & duplex.
  2. sshd_config to turn off the DNS checkd and turn KerberosAuthentication off if you do not use.
