Network problem after sys-unconfig
I am running Solaris 8 and I have problem with configuration of the network after running sys-unconfig command:
- I ran "sys-unconfig" command then the system reboot to "ok" prompt. I did a "boot disk" command and the system reboot
- I lost all system info including host name and all addresses and dns as a name resolve
- I went back in after reboot and ran the "ifconfig" command for the IP address, mask, and use the "route add default" command for the default router
But all lost again after I reboot the system. My questions are
1) How do I ran the "ifconfig" command so that the system keep all the config after reboot.
2) How do I put back the host name to the system? (I went into /etc and try to change the host name but the "hosts" file is "read only" and I went in as root.)
Manny thanks for help

Hi,
I performed a sys-unconfig on a solaris 10 server twice and it did not ask for a new hostname. I did a fresh install. most of the time I have experienced that it asks for a new hostname. what happened?
I know I could have edited some files but I prefer not to.
thanks in advance,

I did a sys-unconfig to change the domainname, Ip, subnet, hostname, and pretty much everything else that sys-unconfig handles. Upon reboot, it is toast. I did this all without the network cable plugged in.

reboot
REBOOT(8) BSD System Manager's Manual REBOOT(8)
NAME
reboot, halt -- stopping and restarting the system
SYNOPSIS
halt [-lnq]
reboot [-lnq]
DESCRIPTION
The halt and reboot utilities flush the file system cache to disk, send all running processes a SIGTERM (and subsequently a SIGKILL) and,
respectively, halt or restart the system. The action is logged, including entering a shutdown record into the wtmp(5) file.
The options are as follows:
-l The halt or reboot is not logged to the system log. This option is intended for applications such as shutdown(8), that call reboot
or halt and log this themselves.
-n The file system cache is not flushed. This option should probably not be used.
-q The system is halted or restarted quickly and ungracefully, and only the flushing of the file system cache is performed (if the -n
option is not specified). This option should probably not be used.
Normally, the shutdown(8) utility is used when the system needs to be halted or restarted, giving users advance warning of their impending
doom and cleanly terminating specific programs.
SEE ALSO
wtmp(5), shutdown(8), sync(8)
HISTORY
A reboot utility appeared in Version 6 AT&T UNIX.
