Hi

Ok, I'm still setting up my HP.

My /etc/resolv.conf looks like

domain <my subdomain>
nameserver <dns-server-1>
nameserver <dns-server-2>

When I go to http://66.94.230.33, I get a nice Yahoo Page (minus graphics)

However, when I go to http://www.yahoo.com, the domain name cannot be
resolved. The DNS servers are correct; I use them on other machines.

I tried putting my router ip in /etc/defaultrouter, which fixes this
problem in Solaris, but apparently HP does not use the same convention.

My host search order is /etc/hosts, nis, dns.

What do I have to do to get my computer to be able to surf the net?

Thank you,
Tony G.

hp-ux is no solaris /etc/defaultrouter has no meaning in this case.
Can you ping the dns servers? If not set the route correctly. Easiest done
with sam. go to network settings and find something like default gateway.
Check your netmask also.

If you don't use nis remove the nis entry in the /etc/nsswitch.conf name
lookup list.

If you're able to reach the web site via IP address, the problem isn't
routing. However, HP-UX configures this through /etc/rc.config.d/netconf
(along with IP addresses for the interfaces).

The form of the resolv.conf looks good and if you use the same nameservers
on other systems with no problems, things should work for you. And you say
you have nsswitch.conf configured to use files, nis, then dns so that should
be good too.

The one thing that comes to mind is to check the permissions on
nsswitch.conf and resolv.conf. I vaguely recall having some difficulties at
my previous job while trying to lock some file permissions down and
discovered that if resolv.conf wasn't world readable, things didn't work.

First of all, thank you for the suggestions so far...

I have removed the nis entry from nsswitch.conf, but with no luck.


I'm quite frustrated by this. I have tried to provide all the
information anyone might need to diagnose this problem... I'm sure the
solution is very simple, but I just don't know hpux well enough. And I
have not been able to find any good answers in the admin manuals I have
downloaded; perhapse I am looking in the wrong place.

Will this help anyone?

SUMMARY

My computer has access to the local LAN. It has access to the internet,
and can see my Domain Name Servers and even Yahoo.com when asked via IP.
I have a sane routing table (afaik), but cannot add a new route. It
seems as though hpux simply does not know to use the DNS servers to
resolve domain names.

Thank you again for any help you might provide,
Tony G.

Oh, one more thing that might help:

Lan config:
===============================
# ifconfig lan0
lan0: flags=843<UP,BROADCAST,RUNNING,MULTICAST>
inet <my-ip-address> netmask ffffff00 broadcast 192.168.0.255

The NOTFOUND=return after files prevent the use of the dns if the host
is not found in the /etc/hosts. Check the man page or the examples
files.

Excellent, thank you

I changed my nsswitch.conf so that it was:
hosts: files [NOTFOUND=continue...dns...

Now internet works. Thank you so much.

In Linux, it just assumes that if you have more than one entry, you want
to move from one to the next. It doesn't distinguish between
unavailable and not found. Neat. Perhaps this is the default behavior
in hpux too (if one were to exclude the [NOTFOUND...].

Anyway, thanks again.
Tony G.

P.S. I love your email signature... will have to use that sometime.

The behavior is the same on HP-UX as on Linux. The "[... ]" is not required and
there is an implied behaviour of "[SUCCESS=return NOTFOUND=continue
UNAVAIL=continue TRYAGAIN=continue]".
