Hi. I have installed Solaris 8 and I am trying to configure the network settings. For some reason every time I reboot, my card loses its configuration. I can run ifconfig and the only IP address bound to my card (on either interface) is I can change that to a valid IP address on my network and connect to the network, but I cannot access anything outside. I do not know where to tll UNIX my gateway IP address. I guess this is really two questions. Thanks in advance for any help.

The network information is all stored in text files in the /etc directory. The installer should have prompted you for this information during the install and written all this information to disk.

/etc/defaultrouter contains the IP (or hostname if it's in the hosts file) of the gateway

/etc/hosts contains the IP and hostname of hosts known to the computer including the hosts own IP

/etc/nodename contains the hostname

/etc/resolv.conf contains DNS info in the format of:
nameserver {DNS_server_IP}

If this gets you on the Internet but you are unable to resolve hostnames (DNS), you need to edit the /etc/nsswitch.conf file and add dns into the hosts line.

There should be man pages on these filenames defining the exact format. Information plugged into the system with ifconfig is only temporary and is flushed when you reboot.

Hi there,
you must do the above mentioned things, of course, but there may be another mistake you made, if i really understood your problem:
The is the loopback address, and as far as i know, you must not delete this adress, but leave it in your /etc/hosts as localhost.
(again: as far as i know....)

The loopback interface is different than a hardware interface. Loopback is internal to the kernel and never sees an external device. For example, an ifconfig output:

eth0 Link encap:Ethernet HWaddr 00:A0:24:80:52:9F
inet addr: Bcast: Mask:
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
Interrupt:11 Base address:0xd800

eth1 Link encap:Ethernet HWaddr 00:00:C0:31:B3:95
inet addr: Bcast: Mask:
RX packets:1463590 errors:0 dropped:0 overruns:0 frame:0
TX packets:1401027 errors:0 dropped:0 overruns:0 carrier:0
collisions:170 txqueuelen:100
Interrupt:10 Base address:0x310 Memory:cc000-d0000

lo Link encap:Local Loopback
inet addr: Mask:
RX packets:4492 errors:0 dropped:0 overruns:0 frame:0
TX packets:4492 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
Note that the loopback interface is not the same as the ethernet interfaces.

more solaris questions

We may be having the same issue.....more details...
I'm attmpting to attach this box through a cable modem receiving DHCP addresses. The ifconfig command only returns a single interface lo0, with the loopback line mentioned above. Using webstart3.0 doesn't get networking done properly. I'm assuming that since I can only resolve the loopback interface that I need to initialize the ethernet card via a command line? I'm also not sure I've been able to resolve the MAC address correctly, is there a command line query for the MAC address?

Sun Docs are no help at all so far.

Thanks in advance

Try this thread for some discussions on arp, loopback, and virtual interfaces:

half solved looks like i'm halfway's what I learned (trial and error)

The lo0: interface (loopback) cannot be configured to DHCP, it must be a default system setting. However, by creating a file hostname.hme0 in the /etc directory (just a blank datafile) I was able to get the ifconfig command to initialize a useable interface. The following command got me a pingable connection out

ifconfig hme0 dhcp

thats the halfway part....I can ping numerical addresses etc., but cannot resolve names such a suggestions?
