Using 3Com LanModem with HP-UX 11.0

Jim Pryde_1 — Fri, 15 Sep 2000 14:54:49 GMT

I have a small LAN using a 3Com 56k LanModem model 3C886A. The 3Com acts as a DHCP server and a modem. Have added a HP workstation to the network..
Can ping and logon to the LanModem, But can not get Netscape to connect to my isp. Have another system running Linux that works fine. I have setup the HP as a DHCP client. The LanModem has an IP of 192.168.1.1. Any ideas on what I may have overlooked with the 11.0 setup would be appriciated.. Called 3Com support, but they don't seem to know how UNIX works.

A couple of clarifications and suggestions:

1. Does your HP box successfully get an IP address from the LanModem?
2. If it does, is it a valid IP? Is the LanModem doing some sort of Network Address Translation? (because 192.168.X.X are unrouteable addresses)
3. you said that you can ping the lanmodem - can you ping past the lanmodem? (ie. can you ping your ISP)
4. If you can get past the lanmodem, try the following -
# telnet your_isp's_web 80
GET /
this is what netscape would do if you tried to contact the ISP's webserver.

5. Have you tried poking your ISP's IP address in your browser?
6. Can you provide more information when you say that netscape cannot contact your ISP? what is the error message.

I don't think I have DHCP set up correctly.. After booting the /etc/auto.parms.log states that dhcp in not enabled. The file /etc/rc.config.d/netconf the line for DHCP
should be set to 1. BUT when the system boots it somhow gets reset to 0.
So, The answer to the first question would be NO. In netconf I put in the address
192.168.1.4 as the IP address. I tried leaveing this field blank -to be filled in by DHCP,
but then CD would not load.

If CDE is not working after the changes, try setting the /etc/nsswitch.conf
host: files
and make sure that you have a localhost definition in your /etc/hosts file.

I would suggest that you use you SAM to set up DHCP. it would help if you would post some of your error logs.
