HP-UX ifconfig question.
This will most likely be a real dumb question for a HP-UX admin, but here it goes anyhow.
lan0 - is up and configured
lan1 - is down, I want to bring it up.
lanconfig....ifconfig is there a difference?
My real question is, in solaris there is an /etc/hostname."?" file, is there a corresponding file in HP-UX. I see one, for the existing NIC but the naming convention seems strange to me.
I.E. HP-UX: /etc/hostname.btlan4
lanscan shows no lan4, rather a lan0 and 1.
If someone could point me to the documentation or give me a quick reply it'd be much appreciated.
HP-UX 10.20 (Yah she's old)

SHMIF(4) BSD Kernel Interfaces Manual SHMIF(4)
NAME
shmif -- rump shared memory network interface
SYNOPSIS
#include <rump/rump.h>
int
rump_pub_shmif_create(const char *path, int *ifnum);
DESCRIPTION
The shmif interface uses a memory mapped regular file as a virtual Ethernet bus. All interfaces connected to the same bus see each others'
traffic.
Using a memory mapped regular file as a bus has two implications:
1. The bus identifier is not in flat global namespace.
2. Configuring and using the interface is possible without superuser privileges on the host (normal host file access permissions for the
bus hold).
It is not possible to directly access the host networking facilities from a rump virtual kernel using purely shmif. However, traffic can be
routed to another rump kernel instance which provides both shmif and virt(4) networking.
An shmif interface can be created in two ways:
o Programmatically by calling rump_pub_shmif_create(). The bus pathname is passed in path. The number of the newly created interface is
available after a successful call by dereferencing ifnum.
o Dynamically at runtime with ifconfig(8) or equivalent using the create command. In this case the bus path must be configured with
ifconfig(8) linkstr before the interface address can be configured.
Destroying an shmif interface is possible only via ifconfig(8) destroy.
