***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.

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:

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?

I'm trying to figure out what circumstances would cause an Open Solaris 11.2 host to switch itself from a static to a DHCP ip address upon reboot. This has only happened once but is a cause for some concern as this machine will be part of a web server pool.
Nothing has changed on the LAN that... (2 Replies)

They are not using dhcp.

sigset(3C) sigset(3C)
NAME
sigset(), sighold(), sigrelse(), sigignore() - signal management
SYNOPSIS
DESCRIPTION
The system defines a set of signals that can be delivered to a process. The set of signals is defined in signal(5), along with the meaning
and side effects of each signal. An alternate mechanism for handling these signals is defined here. The facilities described here should
not be used in conjunction with the other facilities described under signal(2) and sigspace(2).
allows the calling process to choose one of four ways to handle the receipt of a specific signal. sig specifies the signal and func speci-
fies the action handler.
sig can be any one of the signals described under signal(5) except or
func is assigned one of four values: or a function address. The actions prescribed by and are described under signal(5). The action pre-
scribed by and function address are described below:
Hold signal.
The signal sig is held upon receipt. Any pending signal of this signal type remains held. Only one signal of each type
is held.
Note: the signals and cannot be held.
function address Catch signal.
func must be a pointer to a function, the signal-catching handler, that is called when signal sig occurs. specifies that
the process calls this function upon receipt of signal sig. Any pending signal of this type is released. This handler
address is retained across calls to the other signal management functions listed here. Upon receipt of signal sig, the
receiving process executes the signal-catching function pointed to by func as described under signal(5) with the follow-
ing differences:
Before calling the signal-catching handler, the defined action of sig is set to During a normal return from the signal-
catching handler, the defined action is restored to func and any held signal of this type is released. If a non-local
goto (longjmp(3C)) is taken, must be called to restore the defined action to func and release any held signal of this
type.
holds the signal sig. restores the defined action of sig to that specified previously by and are used to establish critical regions of
code. is analogous to raising the priority level and deferring or holding a signal until the priority is lowered by
sets the action for signal sig to (see signal(5)).
RETURN VALUE
Upon successful completion, returns the previous value of the defined action for the specified signal sig. Otherwise, a value of is
returned and is set to indicate the error. is defined in
For the other functions, a 0 value indicates that the call succeeded. A -1 return value indicates an error occurred and is set to indicate
the reason.
ERRORS
fails and the defined action for sig is not changed if any of the following occur:
The func argument points to memory that is not a valid part of the process address space. Reliable detection of this
error is implementation dependent.
and and fail and the defined action for sig is not changed if any of the following occur:
sig is not a valid signal number.
An attempt is made to ignore, hold, or supply a handler
for a signal that cannot be ignored, held, or caught; see signal(5).
WARNINGS
These signal facilities should not be used in conjunction with signal(2) and sigspace(2).
