HP-UX DHCP Client

[Alex_145]

Hi All,
Have two questions.
How I'll be able to find out: is HP-UX using DHCP and if using - what is DHCP server's IP (or/and Name).
Thx.

Hi,

Check /etc/rc.config.d/netconf

INTERFACE_NAME[0]="lan0"
IP_ADDRESS[0]=""
SUBNET_MASK[0]="255.255.255.255"
BROADCAST_ADDRESS[0]=""
INTERFACE_STATE[0]=""
DHCP_ENABLE[0]=1

Interface 0
ipadres not configured
dhcp =1 is enabled.

Hope it helps,

Robert-Jan.

Hi,
to see if your hpux is on dhcp,
you should look at

/etc/rc.config.d/netconf


If, for an interface, the DHCP_ENABLE is equal to 1, it is a dhcp client.

For netconf:
# DHCP_ENABLE Determines whether or not DHCP client functionality
# will be enabled on the network interface (see
# auto_parms(1M), dhcpclient(1M)). DHCP clients get
# their IP address assignments from DHCP servers.
# 1 enables DHCP client functionality; 0 disables it.
#


The dhcp server is obtained using a broadcast on the net, nut i don't know how to find it.

Thanks. But how about second question? Where I can find DHCP server's adderess? I know about /etc/dhcpclient.data file, but it's format is not enough clear for me (see HP-UX Reference N B2355-90688, section 1M-167). Is this plain text file or binary? When it's text file -why in the example I see "08 4 0"?

Robert-Jan, Massimo,
may be BROADCAST_ADDRESS[i] is 'sought quantity'?

[Allyn Fratkin]

as root, run this command: /usr/lbin/dhcpdb2conf

[Alex_145]

Allyn,
would you please send needed dhcpdb2conf command string and it's output (as an example).
Thanks.

Hi,
i'm not sure about the meaning of "sought quantity", but usually any value other than 0 mean to activate the dhcp.

Massimo, I'd in view that probably BROADCAST_ADDRESS[i] is DHCP Server's address for corresponding i-th interface. What do you think (or know) about BROADCAST_ADDRESS == DHCP Server address?

Hi Alex,

Take a look at this question.
