New Configurable Resolver Options
The timeout value is a function of the RES_RETRY and RES_RETRANS
options of the resolver routines. It is currently hardcoded as 5000
milliseconds for RES_RETRANS and 4 milliseconds for RES_RETRY. This
results in a timeout value of 75 seconds. This timeout value is obtained
when you assume that there is one nameserver. When there are multiple
nameservers, the timeout value will increase. Hence, to help achieve
shorter timeout values, and better performance, the resolver options
RES_RETRY and RES_RETRANS are now configurable.
These resolver options can be configured using any of the three methods
shown below. They are listedin priority order withthe first listed method
having the highest priority.
1. Use environment variables.
2. Use resolver configuration file /etc/resolv.conf.
3. Use the new APIs defined in (set_resfield).
The RES_RETRY and RES_RETRANS options can be set with any positive
non-zero integer.
“PAM-ized” rexecd and remshd
The rexecd and remshd services on HP-UX 11i now use Pluggable
Authentication Modules (PAM) for authentication.
You can take advantage of using an authentication mechanism of your
choice like DCE Integrated Login, UNIX, or Kerberos by making a
change in the /etc/pam.conf file. By default, if you do not edit the
/etc/pam.conf file, the rexec and the remsh services will use the
authentication mechanism specified by the OTHER directive in the
/etc/pam.conf file.
The earlier version of rexecd and remshd allowed only those UNIX users
who were included in /etc/passwd to use the rexecd and remshd
