Strange Error in HPUX 11.0 Sendmail

[Guest_imported]

Hi,

I have configured sendmail to use MS Exchange. However, it will only works if i use /etc/resolv.conf. By doing so, i found that my system cannot will not read /etc/hosts file.
Meaning, some of the hosts defined in HOSTS cannot be ping using hostname. But disabling RESOLV.CONF everything will back to normal - but can't sendmail again.
Pls advise .

Lets have a look at your /etc/resolv.conf file.

Hi rjdscs,

Pls look at below log,

# ping ultra5
PING ultra5: 64 byte packets
64 bytes from 192.168.1.147: icmp_seq=0. time=0. ms
64 bytes from 192.168.1.147: icmp_seq=1. time=0. ms

# ping ultra5

# cat /etc/resolv.conf

# mv /etc/resolv.conf /etc/resolv.bak
# ping ultra5

# uname -a
HP-UX sakura B.11.00 U 9000/785 2016365696 unlimited-user license

I also try to edit RESOLV.CONF to this way,
domain mydomain.com
nameserver 192.168.1.10

Somehow after setting the DNS, the system do not read the hosts file anymore !


Thank you for your attention .

Hi folks

I have just solved my problem. There is some priorty settings for name resolution. Just create a /etc/nsswitch.conf file. Put this parameter ,
hosts: files

That's all !

Cheers :>))))
