@Peasant Thanks for your reply. As an FYI, I have put the above question to Oracle and am waiting for a reply. This is a new x86 machine with no prior O/S installed. What makes this more of a mystery is that a further reboot (cold) invoked the original static ip?
Beadm shows default grub2 as expected:
You raise a good point, however, on NWAM. It is my understanding that NWAM would dynamically respond to either user input or a change in network configuration. Which begs the question "what happened at re-boot"? because AFAIK nothing changed. A I am fairly new to this, what advice could you offer on which log files I should tail/interrogate. Again, many thanks.
***Newbie alert***
What's the easiest way to accomplish this? An admin left our company and I have taken over his HP Workstation and moved it to a different location that is on a different IP segment.
I have performed a number of google searches but the steps I have followed haven't worked.

Hi All,
I am facing a connection problem with Oracle 10g on Solaris 10 when my application (started by /etc/rc3.d at node reboot) tries to establish a session after reboot of the node where my application is running (NCR UNIX (MP RAS)).
I find that my application (run as a deamon process)... (1 Reply)
I have a USB Wireless Adapter using the rum0 driver. All I want to do is set a perminent static IP for the onboard wired interface elxl0. I can plumb the wired interface up fine on the fly, but when I try to save the static IP over a reboot, I lose the IP address assigned to rum0 from my wireless... (1 Reply)
I am pretty new to this. My router was earlier configured to enable DHCP, thus my UNIX box is using the dhcp address, i.e. I have to do a ifconfig dhcp hme0 start. Since I am planning to use my NT as a web server, I needed to use the static IP address. How do I configure the unix box to use the... (5 Replies)
I am trying to write a set of scripts for my Ubuntu 810 Server to allow a user to change from DHCP to a user-supplied Static IP, Subnet, Gateway and DNS Servers.
So far I have the following, where $USERCHOICE is a user-entered value in each case:
ifconfig eth0 down && ifconfig eth0 $USERCHOICE... (1 Reply)
Hi,
I am using RHEL 5.1 and i would like to know,
how to find the whether my system is using DHCP or STATIC IP
with out looking at /etc/sysconfig/network-scripts/ifconfig-eth0 configuration file.

Hey guys ,
YEs this is probably silly for most but i am new to this forum and solaris . i am curious to know if the ip address we have for our solaris server is static or dhcp . how can i tell ? will ifconfig -a tell me this ? or other commands?
Thanks in advance (1 Reply)
Hi All,
Could you please explain the purpose of assigning the static IP by using the DHCP Concept. Like by using the clients MAC address we assign the static IP Address. Waiting for your reply. Thanks in Advance. (6 Replies)
Hi,
I can find the IP details whether it is Static or dynamic in Linux machine from the location /etc/sysconfig/network-scripts/ifconfig-eth0 configuration file.
Can someone suggest a location to find the same in HP UX machines?

We have 2 solaris 10 t5240 servers with static IP addresses on nxge0 I/F which were rebooted a few days back with a known good config that has been in place for years (for /etc/hosts, /etc/hostname.nxge0, /etc/netmasks, etc)
They are not using dhcp.
About the same time today, both of their... (7 Replies)

dhcp - Dynamic Host Configuration Protocol
DESCRIPTION
Dynamic Host Configuration Protocol (DHCP) enables host systems in a TCP/IP network to be configured automatically for the network as they
boot. DHCP uses a client/server mechanism: servers store configuration information for clients, and provide that information upon a
client's request. The information can include the client's IP address and information about network services available to the client.
This manual page provides a brief summary of the Solaris DHCP implementation.
Solaris DHCP Client
The Solaris DHCP client is implemented as background daemon, dhcpagent(1M). This daemon is started automatically during bootup if there
exists at least one dhcp.interface file in /etc. Only interfaces with a corresponding /etc/dhcp.interface file are automatically configured
during boot. Network parameters needed for system configuration during bootup are extracted from the information recieved by the daemon
through the use of the dhcpinfo(1) command. The daemon's default behavior can be altered by changing the tunables in the /etc/default/dhc-
pagent file. The daemon is controlled by the ifconfig(1M) utility. Check the status of the daemon using the netstat(1M) and ifconfig(1M)
commands.
Solaris DHCP Server
The Solaris DHCP server is implemented as a background daemon, in.dhcpd(1M). This daemon can deliver network configuration information to
either BOOTP or DHCP clients. The Solaris DHCP service can be managed using the dhcpmgr(1M) GUI or the command line utilities dhcpcon-
fig(1M), dhtadm(1M), and pntadm(1M).
DHCP Configuration Tables
The Solaris DHCP server stores client configuration information in the following two types of tables:
dhcptab tables Contain macros and options (also known as symbols), used to construct a package of configuration information to
send to each DHCP client. There exists only one dhcptab for the DHCP service. The dhcptab(4) can be viewed and mod-
ified using the dhtadm(1M) command or dhcpmgr(1M) graphical utility. See dhcptab(4) for more information about the
syntax of dhcptab records. See dhcp_inittab(4) for more information about the DHCP options and symbols.
DHCP network tables DHCP network tables, which contain mappings of client IDs to IP addresses and parameters associated with those
addresses. Network tables are named with the IP address of the network, and can be created, viewed, and modified
using the pntadm command or dhcpmgr graphical utility. See dhcp_network(4) for more information about network
tables.
