Operating Systems AIX Can not Ping Gateway Post 302400531 by cdub50 on Wednesday 3rd of March 2010 12:44:25 PM

I configured en0 interface and I have a cable plugged into port 1 in the back of the server as there is only one nic installed with two interfaces and I have configured en0. Below is the output of the netstat -rn command.



Code:
#	netstat	-rn
Routing	tables
Destination	Gateway	Flags	Refs	Use	If	Exp	Groups

Route	Tree	for	Protocol	Family	2	(Internet):
default	10.52.44.1	UG	0	65	en0	-	-

Route	Tree	for	Protocol	Family	24	(Internet	v6):

#

it looks like when I ping the ip I set 10.52.44.250 it is replying through the loop back interface and not en0 why? Is there something else I need to configure to communicate on the network?

Thanks for the Help Smilie

NAME
en -- device driver for Midway-based ATM interfaces SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device en device atm device utopia Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_en_load="YES" DESCRIPTION
The en device driver supports Midway-based ATM interfaces including the Efficient Networks, Inc. ENI-155 and Adaptec ANA-59x0. Midway is an AAL5 SAR (Segmentation and Reassembly) chip. For configuring the card for IP see natmip(4). The following sysctls are recognized by the driver additionally to those handled by utopia(4): hw.atm.enX.istats Contains an array of uint32_t with internal driver statistics. hw.atm.enX.debug This is a bit map of debugging options. This variable is only available when the driver is compiled with debugging support. The driver supports the media options sdh, noscramb and unassigned (see utopia(4)). DIAGNOSTICS
en0 <Efficient Networks ENI-155p> rev 0 int a irq 5 on pci0:16 en0: ATM midway v0, board IDs 6.0, Utopia (pipelined), 512KB on-board RAM en0: maximum DMA burst length = 64 bytes en0: 7 32KB receive buffers, 8 32KB transmit buffers allocated CAVEATS
The driver extensively uses DMA on PCI. The first generation PCI chipsets do not work or exhibit poor performance. SEE ALSO
natm(4), natmip(4), utopia(4), ifconfig(8), route(8) AUTHORS
Chuck Cranor of Washington University implemented en driver in 1996 for NetBSD. BSD
