Hi there, I have a newbie networking problem. I've never really done any networking before. I recently got an UltraSPARC 10 running Solaris 8, and decided it would be fun, useful, and educational to network it to my debian box.
My debian box connects to the internet sometimes via ppp, but is generally
a stand-alone. I made a cross over ethernet cable (by reversing the color
order of the subcables on one side) and connected my two boxes directly.
I installed my ethernet card and recompiled my kernel (I'm running 2.4.2)
to support it. Then in my /etc/network/interfaces file I put:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.0.2
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
as per the local network ip recommendations of the net howto. I originally
also had a gateway ip, but this interfered with ppp (since newer versions
of pppd don't override a default gateway). I don't think I need one for
a network this small, do I?
I'm not immediately concerned with naming, since I would like to establish
a connection between my two boxes in some manner first, but I edited /etc/hosts
to give my Sun a name and that seems to work (I type telnet hostname and it
attempts to connect to the correct ip, at least).
My ethernet card is constantly clicking on and off (that is, the small green
light on the back of it switches on and off, accompanied by a small clicking
sound.) I presume this is because it is probing for a network?
When I do netstat -rnv I get:
$ netstat -rnv

and from route:

and from ifconfig:

In my /etc/networks I have
localnet 192.168.0.0
I'm not sure what else I would need to set on the debian side. I guess my
question is, do you see anything more I should do or check, or can I conclude
with reasonable certainty that if I'm not getting a connection it's Solaris'
fault?
I'd imagine some of you know about Solaris networking, so if you have the
stomach for it, here is my Solaris side configuration. My SPARC does not
connect to the internet; eventually I would like to route the net through
my Debian box, but for the moment I'll be happy with just being able to ping
one from the other.
On my SPARC, /dev/hme0 is my ethernet card.
When I do a netstat -rnv, sun-side, I get
# netstat -rnv

(sorry about the formatting, Solaris doesn't believe in the 80-char rule).
When I do ifconfig -a, I get:
# ifconfig -a

inet 127.0.0.1 netmask ff000000

inet 192.168.0.1 netmask ffffff00 broadcast 192.168.0.255
ether 8:0:20:f0:d6:92
/dev/lo0 is the loopback device.
Related network setup files:
# cat /etc/hostname.hme0
mithras
# cat /etc/inet/hosts
127.0.0.1 localhost loghost
192.168.0.1 mithras
192.168.0.2 purple
# cat /etc/inet/netmasks
192.168.0.0 255.255.255.0
I have tried putting my IP directly into /etc/hostname.hme0, but it didn't
help and rtfm'ing told me that the way I have it setup is the prefered way.
At any rate, it seems to know that 192.168.0.1 is its IP.
Also, I couldn't figure out where to specify the broadcast IP, but notice
(in the output of ifconfig -a) that it correctly discerned it.
(that would be 192.168.0.255). Do any of you know where this can be
set manually?
On my sun box, when I try to telnet to my debian box I get a 'network is
unreachable' error. On my debian box, I get a 'No route to host'.
So, from this, were any of you able to tell easily which (or both) is
the culprit responsible for my non-networked-ness, and how I might be
able to fix it? Sorry to spam you all with so much Solaris crap, but
the people who claim to know solaris on IRC are most unhelpful (contrasted
to Linux people!) and the docs (when they exist) are cryptic at best.
I'm starting to get frustrated, so I hope someone on here can help me
out. I only have one monitor for my two boxes, so everytime I need to
do something on the other I have to take the cable out of one, stick
it in the other, etc... you know, major pain. It'll be delicious when
they are networked.
Thanks in advance.
