Networking Problems w/ Solaris 8
 

I just recently was given a Sun Ultra Sparc 2 with 2 296MhZ Processors and 1 GB of Ram and Solaris 8 installed. I have never used Solaris but have a brief knowledge of Unix. The box is freshly setup and I am having some networking problems. I did a sys-unconfig and "re-did" the network setup. This box is plugged into a switch which is intern pluged into a router. From the Sun box I am able to ping and talk to the router (Linksys router, I can bring up the GUI Admin interface on it and the router is connected to a cable modem) and from my other computers behind the router I can connect to the Sun system. The problem is I can NOT connect to any external websites. What do I need to do to do this??
Also how can I set up this system so I can remotely connect to it from Windows machines (with a GUI interface) from within the network and I want to get this set up so it can be a network (internal only) file server.
And finally in the future I would like to set this up so I can connect to it from outside the internal network I have. And security is VERY IMPORTANT to me.

Thanks!

is your DNS setting OK ?
Can you connect to outside hosts by using their IP addresses ?

No I can not connect to outside websites via IP address. Exactly how do I set up the DNS stuff on the Solaris box. Remember connecting to a router (how do i edit the system to see that router) which then connects to a cable modem to the outside world.

Do you have a default route set? Is the output of "netstat -rn" correct?

Just another note. I can connect to the router fine but when I try to connect to my other desktop that is running IIS 5.0 (via ip address) it will not connect.

Is your desktop on the same lan as your ultrasparc 2 ?
if true, perhaps have you a netmask issue.

To permanently set a defaultrouter, see man defaultrouter.

Yes they are both on the same lan. I do not have a domain just have a workgroup that is named HGOLDNET and the subnet mask is the default 255.255.255.0 so what could be going on here??

Are you saying you can connect from inside computers to the sun box but not in the reverse way ?

can you issue the commands:
netstat -rn
ifconfig -a
arp -a
and send us the results.
