[SunHELP] newbie unclear on post installation steps of solaris 8 on ultra sparc...

[Marvin Cummings]

Whenever I modify the /etc/hosts file to show a FQDN for my sun box,
mysunsrvr.mydomain.com, I'm no longer able to ping any internal or
external resources. This is after I modify the file and reboot the
system. However if leave my system name as it is, mysunsrvr, and reboot
then all is fine. I'm able to ping internal and external resources. I'm
still unable to access any external sites via the Netscape browser.

If you're using vi, do :w!<ENTER> and it will write it anyway.

I had a few problems initially, but I think the problem was my hardware
was
set up wrong. I recommend you read both the FAQ and the install manual
before
installing, and make sure you have things like the IDE drive on
IDE0:master,
and so on. 

There's also a web site with a lot of good post-install stuff, hmm, hold
on...

Only thing I haven't seen anywhere is how to block outside ping
requests,
which is important to me (both for stealth and because I've been ping
flooded
in the past). I figured that out well enough. It doesn't seem to stop a
traceroute, but it no longer responds to pings from outside, does
respond to
them from inside, and also accepts ICMP responses (when you ping an
outside
system from inside). 

It's not perfect, but it's free, and it beats the heck out of what I had
before. And "free" is pretty important right now.
