Why do I have to run sys-unconfig every day on my U2, otherwise it
stops seeing the internet or email?

Nothing fancy here. A straight, unmodified install of Solaris 9
on a dual 200 MHz Ultra 2 with a gig of RAM, HME0 onboard ethernet
in use, HME1 10/100 ethernet NOT in use, 2 9.1gb drives, and that's
about the total extent of it.

When I power it up in the afternoon or evening or whenever it is that
I want to use it (It doesn't stay on 24/7 for a number of reasons
including heat, noise, and political reasons), it NEVER sees email
or the internet unless I sys-unconfig it and reconfigure it, and then
it's good to go until I shut it off.

Any ideas?

A few more details would be helpful. How does it connect to the
internet? How do you read email? Does it have a fixed IP ? Contents of
/etc/hosts ? contents of /etc/resolv.conf ...

I'm no networking expert, but know enough to know you have not
supplied sufficient information for anyone to really help you.

Connection is via DHCP, direct line from the HME0 port to a 4 port hub,
sharing a cable modem with my PC. Mail client is Netscape, as is the
browser.

This configuration is as dead simple as I know how to make it. Once
I run sys-unconfig and then reconfigure it, DHCP is enabled, no name
service, and regional settings as appropriate. That's ALL. Straight
to the hub, then to the cable modem.

And the funny thing is, not too long ago, it always worked without
monkeying with it...but I know now that the Solaris install I was using
then was INCOMPLETE. The entire 2nd disc's contents had NOT been
installed.

I would replace the hub with a broadband router, most cable ISP only
provide single dynamic/static IP at all time, if you have both of your
machines
on, your cable modem will not know which MAC to choose from.

Does this problem happen all the time or only after someone use the PC
to connect first?

Has your ISP recently extand their DHCP server IP releasing time?
If you don't want to change the hub into a router, you might want to release
the ip manually after each use in case their DHCP server doesn't renew the
client database too often.

That's about as much as I know....

Good morning all!

Post your technical queries to ap-csc-english@sun.com if you are based in
the Asia Pacific region (including Australia and New Zealand). This is the
Technical Support area. They should be able to point you in the right
direction.

However, unless you have a Cobalt machine - all other hardware and software
support requires you to have a valid maintenance contract number with Sun.
If you don't have one, be prepared to pay for time and materials costs.

Best regards
Andrew
