Duc, I have seen several times the /etc/hosts and /etc/netmasks files
with no symbolic links to the /etc/inet/hosts and /etc/inet/netmasks
files.
That's why every time I need to do changes to these files I change the
files in the /etc directory. After that, I have the files in the /etc
directory with different information respect to the files in the
/etc/inet directory.
I checked the Sun docs and they say that the symbolic links is used for
compatibility with the BSD-based operating systems.
In my case, I have never had a problem because of this but I really want
to know why the symbolic links were broken.

These are the files (for B/C/D-style boxes, at least) that need to be
edited/created to effect the network communication on the second
Ethernet interface:
/etc/hostname.hme[12] or hostname.le[123]
/etc/defaultrouter (new, need to create)
/etc/resolv.conf (new, need to create)
/etc/nsswitch.conf (edit to add 'dns' for hosts)
/etc/inet/hosts (edit to add 2nd port name and IP
address)
/etc/inet/netmasks (edit to add subnet mask)
The format for those files that you need to create is left as an
exercize for you (one hint: Google).
If you follow the instructions given in this archived message:
//www.freelists.org/archives/foxboro/01-2003/msg00092.html
which is essentially what I wrote earlier, there is no need to edit the
/etc/rc* files.

Yes it works but I had to put the route command in the /etc/rc2
initialisation script. One strange things happen. The 2nd Ethernet port
works fine for some time. Then the connection drops and I cannot ping =
=3D
=3D3D
remote
computer. When I see from "ifconfig -a"
The 2nd Ethernet port goes to POINT TO POINT instead of broadcast. Also
My
given netmask is not reflected in "ifconfig -a". Same is the case with
broadcast address. But still it communicates for a while.
Can you help on this.
Regards,
Kashif Ijaz

Edit /etc/netmasks and put your desired subnet mask there. For your
gateway use /etc/defaultrouter. You may have to create the file
defaultrouter if it's not already present.
I don't have an F box so you shouldn't trust me, but I believe the
procedure is the same.
