I have a SUN WKS Solaris 2.6 & try to connect to the internet.  I asked our DNS group to added my WKS to DNS.  I can use DNS in the LAN environment, but I can't connect to the internet with netscpae. I am a stand alone wks & not part of any NIS group.  The two files I configurated are NSSWITCH.CONF & RESOLV.CONF.

The configuration files for NSSWITCH.CONF & RESOLV.CONF

#
# /etc/nsswitch.files:
#
# An example file that could be copied over to /etc/nsswitch.conf; it
# does not use any naming service.
#
# "hosts:" and "services:" in this file are used only if the
# /etc/netconfig file has a "-" for nametoaddr_libs of "inet" transports.

netgroup:   files

RESOLV.CONF

nameserver      155.1.28.22                                                    
                                                         
THX in Advance...

Can you ping your specified nameservers?
If so, does nslookup give you IP addresses for names?
If so, can you ping these names or IP addresses?
If not you have a routing problem, post result of:
  netstat -rn

Thanks for your response ahoffmann.

I changed the Resolv.conf to match the DNS I am using for Windows 95. I can ping all the servers with names & IPs.

Just to rule out the obvious, check for /etc/defaultdomain and /etc/defaultrouter.  Also run domainname from the command line, set your domain and see if that helps.  Maybe trying entering a site in /etc/hosts.  Are you trying to go through a firewall?

I checked the /etc dir & I don't have a defaultdomain file.  I have the following 2 files:

Default
Defaultrouter

I tried the enter a the yahoo.com site in the host file, it failed to connect.  I am going through a firewall.
I was able to connect to the internal intranet but not the internet.   I am thinking it might be the firewals.

Thx...

Can you ping your wks by name from a LAN PC?
Also run a tracert on a PC (WIN/NT command); it will show if it is going through a firewall:
tracert ahost.adomain.com

Yes, I can ping & telnet to my Sun WKS in the LAN environment from my PC.  When I did a tracert to www.yahoo.com from my Win95 Wks I got the following Infos.



Tracing route to www5.yahoo.com [204.71.177.70]
over a maximum of 30 hops:

  1     1 ms     1 ms     1 ms  h99a.fmr.com [155.1.243.2]
  2  h99a.fmr.com [155.1.243.2]  reports: Destination host unreachable.

Trace complete.

Thx again....

Does your site have a firewall?  Do they have a proxy server?  If so, you'll have to configure netscape to use the proxy server or have your local lan admins to punch a hole in the firewall for you.

arthurd is on the money, try setting up your proxy server to be:

155.1.243.2  (the http port is 8080)

That is the typical port number used (default);  to see if that port is active try:

"telnet 155.1.243.2 8080"

You can also download "traceroute" (I think gnu has it), compile and run that on the workstation.  

or try this:

/usr/sbin/ping -Rvs ahost.adomain.com

If all else fails:  (as root on your station)
snoop mystation >>/tmp/a.log.file
Try connecting again (different screen) and check the packet info in the logfile.  ****CAUTION:  LOG file will grow quickly!!!; don't forget to kill the snoop.

I see a
possible problem with the configuration. The /etc/resolv.conf
file is listed:

RESOLV.CONF

   domain  fmr.com
   nameserver      127.0.0.1
   nameserver      137.199.36.20
   nameserver      155.1.1.15
   nameserver      155.200.144.15
   nameserver      155.1.28.22    

The first nameserver line points to a nameserver on the local host
(127.0.0.1).  There may not be a nameserver on the local host or it
may be misconfigured.  Try commenting out that line and see if it
works.  Also, you should test with something other than netscape.  
netscape caches DNS information, so its hard to tell if it is really
using the network to answer any particular query.  It would be better
to use ping or telnet for testing.
