UX 11iV2 - No ping by hostname

netwalker · #1 (**permalink**) 08-25-2007

Hi.

I just installed the HP-UX 11i V2.
I have problems with CDE - it is inoperative (after logon there is a message box: messaging system failure - or something like that, it asks to check /etc/hosts and network settings).

nslookup works by hostname and IP, hostname shown the correct hostname.
Internet addresses are also accessabble from my computer (for example google).

About ping:
1. It pings to "localhost"
2. It does not ping to my hostname (host name is set via /usr/sbin/sam on file /etc/hosts)

3. It pings to my IP (from remote computers too)

This computer is set to permanent IP address and custom set hostname, no DHCP. Network is based on ADSL modem+router (it provides DNS and DHCP by demand) and switch.

Please help me, to find why there is no ping to my hostname. I beleave, that all problems with CDE destop are comming from this issue.

Please post the contents of these two files:

/etc/resolv.conf

and

/etc/hosts

/etc/resolv.conf

Code:

domain
nameserver 192.168.200.1
nameserver 192.168.200.40
nameserver 127.0.0.1

The last two, I added them in hope, that computer will try to resolve it's hostname from itself.
Maybe I should to start DNS server on it?

/etc/hosts

Code:

127.0.0.1 localhost
192.168.200.40 hp-j5000 loghost

Looks like there is no affect of this file on my system. Without this file the same behavior - nslookup still resolves correctly hostname and IP.

Also, nslookup shows the following warning:

Code:

*** Warning - the local domain os not set.
*** Either hostname should be a domain name,
*** the domain should be specified in /etc/resolv.conf,
*** or shell variable LOCALDOMAIN should be set.

I tryed the set the domain name (I set it as hostname - hp-j5000) in /etc/resolv.conf the behavior was the same, just no that warning.

Type "man 4 resolv.conf" to get the documentation you need.

You have not specified a domain in resolv.conf e.g.

domain murphy.com

You also need to modify /etc/rc.config.d/netconf to include the hostname of your
computer e.g.

HOSTNAME=fpm.murphy.com

Thanks fpmurphy.

No there is no warning during nslookup.
There was a hostname in /etc/rc.config.d/netconf
it was:

Code:

HOSTNAME=hp-j5000

I changed it to:

Code:

HOSTNAME=hp-j5000.magnet.com

Also I added domain to resolv.conf:

Code:

domain magnet.com

However, there is still the same problem:

Code:

#hostname
hp-j5000.magnet.com

#nslookup hp-j5000
Name Server: mygateway1.ar7
Address: 192.168.200.1

Trying DNS
Trying NIS
tooking up FILES
Name: hp-j5000
Address: 192.168.200.40
Alieases: loghost

#ping hp-j5000
ping: unknown host hp-j5000

In other words, the system is still unable to resolve the hostname.
In DNS client, /usr/sbin/sam shows that one of DNS sources is /etc/hosts, but actually the system doesn't apply to this file and still not resolving names.
How to make the system applying to /etc/hosts too?

Thanks.

Your name server at address 192.168.200.1 is not set up correctly.

Is this your DNS server? Did you configure it yourself?
