HPUX 11.11 - HomeNetwork - Setup

[Dietmar_P]

Hi, I recently bought a sencond hand C3700 Workstation for study purpose.
All PC'S workstations are connected through a router (smc barricade) which is connected to the ISP (PPOE). After editing the /etc/hosts file I can reach all the PCs attached to the router but I can't get access to the internet. I configured static ip addresses on the systems. I did not setup a DNS Server in my Environment. Using the MS Windows Systems the access to internet works right away.
How do I need to configure the HPUX system to be able to get into the internet? Rgds Dietmar

Hi Dietmar,


Make sure the DNS address is set in your /etc/resolv.conf file...


ex:
#more /etc/resolv.conf
domain testdrive.hp.com
nameserver 15.170.178.132

Since you have connected the system to your router directly which uses PPOE connection for internet, i think in you case the nameserver IP can point to ur router IP itself. If this does not work, try using the DNS IP provided by your service provider directly in /etc/resolv.conf file.

To test the setup, you could for example try the following from ur HPUX box once you make changes to resolv.conf file,

ping www.yahoo.com

and see wether it gets resolved and pings.

Hi - thanks for the quick response. I changed the the ip address from 192.168.2.22 (local address) to 192.168.2.1 and a traceroute to i.e. www.hp.com works.

But now I run into another problem.
I use KEA!X (a X-Window Tool) on my Windows PC to access the HPUX Box (CDE). When starting mozilla now I receive following error.

# mozilla

Gtk-WARNING **: cannot open display: tiger:0.0
#

Before I could start mozilla to view local html pages.

Any idea? Rgds Dietmar

Hi Dietmar,

I understand from my response that u have changed the IP address. But make sure you change using the command "set_parms" this would take care of updating the required files.

After changing the IP, using set_parms and rebooting, I think ur set up should be working.

Shalom,

For new learners, the set_parms approach is more efficient. However look at the configuration files it generates to get a feel for how the networking works.

Good Luck, have fun.

Hi Senthil,

I ran set_parms addl_netwrk, approved the settings for
Subnetwork mask: 255.255.255.0
Gateway IP address: 192.168.2.1

Domain name: testit.com
DNS server address: 192.168.2.1

and receive following error/warning:
_______________________________________________________________________________

WARNING: This system's current hostname (LION) and address (192.168.2.22)
could not be verified with the name server.

Some possible reasons include:

- This system has not been registered with the name server
- This system's host name or address is incorrect
- The domain, name server host name or address is incorrect
- The name server is unresponsive

If some of the networking parameters for this system are incorrect,
you may adjust them by re-executing "/sbin/set_parms initial" and changing
anything necessary.


Well - the problem now still is - that the X-Session won't run anymore and I can't login to the HPUX using X anymore. I use putty to login.

What would I need to modify to be able to run the X-Sessions again?

Hi Dietmar,

via putty, issue the command "nslookup", in the secondary prompt give the command "policy". Then exit nslookup command. If the policy output gave you dns as the first entry, please modify the hosts part your /etc/nsswitch.conf looks something like this....

hosts: files [NOTFOUND=continue] dns


regards,

P.S: anyway can you paste the output of policy command when run after nslookup.

In my system it looks like this...
--------------------------------------------
td192> nslookup
Using /etc/hosts on: td192

> policy
#Lookups = 2
files [RCCC] dns [RRRR]
> td192>
--------------------------------------------

I have attached my /etc/nsswitch.conf file, so that it could of some help to you.

Hi,

Please reboot the system after u make the change to nsswitch.conf file, so that your CDE subsystem could be reinitiated.

Hi Senthil,

there was no /etc/nsswitch.conf.

I created it manually with following entries:

hosts: files [NOTFOUND=continue] dns
ipnodes: files [NOTFOUND=continue] dns
services: files
networks: files
protocols: files
rpc: files
publickey: files
netgroup: files
automount: files
aliases: files

than ran set_parms addl_netwrk again - and rebooted the system. Now I can connect to the box again using X and connect to the internet.

nslookup returns this. Is that a normal behavour or would I need to modify something else.

# nslookup tiger
*** Can't find server name for address 192.168.2.1: Non-existent domain
*** Default servers are not available
Using /etc/hosts on: LION

looking up FILES
Name: tiger.testit.com
Address: 192.168.2.13
Aliases: tiger

Hi Dietmar,
That means your DNS server was not able to find tiger and hence it used files as i.e. /etc/hosts to seacrh for teh server it got that tiger.

Yes it looks normal.

[Senthil Kumar .A_1]

It looks fine.

Anyway you can cross check by issuing "policy" command after you enter nslookup interactively. Just type the command nslookup.


If file comes first and then later DNS and NIS ... I rechon then the setting is fine.

in my case the output is ...

files [RCCC] dns [RRRR]


Anyway, glad that,it has solved your issues..
