Full Discussion: Core Dumping?
Operating Systems Linux Red Hat Core Dumping? Post 302500341 by fpmurphy on Monday 28th of February 2011 09:21:40 AM

kdump is for kernel crash dumping - not core dumps.

Assuming abrtd is not running, to find the core dump pattern do:
Code:
# sysctl -a | grep core_pattern

and then search for that.

For example
Code:
# sysctl -a | grep core_pattern
kernel.core_pattern = /tmp/core.%p

This means that the core dump files will be generated in the “/tmp” directory. The “%p” extension is used to append the process id of the application that crashed. BTW, the variable kernel.core_pattern can also used to change the name of core dump files so they are not necessarily named "core"

VCONFIG(8)						      System Manager's Manual							VCONFIG(8)

NAME
vconfig - VLAN (802.1q) configuration program. SYNOPSIS
vconfig [lots of long options] DESCRIPTION
The vconfig program allows you to create and remove vlan-devices on a vlan enabled kernel. Vlan-devices are virtual ethernet devices which represents the virtual lans on the physical lan. OPTIONS
add [interface-name] [vlan-id] Creates a vlan-device on [interface-name]. The resulting vlan-device will be called according to the nameing convention set. rem [vlan-device] Removes the named vlan-device. set_flag [vlan-device] 0 | 1 When 1, ethernet header reorders are turned on. Dumping the device will appear as a common ethernet device without vlans. When 0(default) however, ethernet headers are not reordered, which results in vlan tagged packets when dumping the device. Usually the default gives no problems, but some packet filtering programs might have problems with it. set_egress_map [vlan-device] [skb-priority] [vlan-qos] This flags that outbound packets with a particular skb-priority should be tagged with the particular vlan priority vlan-qos. The default vlan priority is 0. set_ingress_map [vlan-device] [skb-priority] [vlan-qos] This flags that inbound packets with the particular vlan priority vlan-qos should be queued with a particular skb-priority. The default skb-priority is 0. set_name_type VLAN_PLUS_VID | VLAN_PLUS_VID_NO_PAD | DEV_PLUS_VID | DEV_PLUS_VID_NO_PAD Sets the way vlan-device names are created. Use vconfig without arguments to see the different formats. NOTES VLAN will use Broadcom's NICE interface when the network device supports it. This is necessary, since usually the hardware of these devices already removes the vlan tag from the ethernet packet. The set_flag option on vlan-devices created on such a physical net- work device will be ignored. Dumping the network-device will show only untagged(non-vlan) traffic, and dumping the vlan-devices will only show traffic intended for that vlan, without the tags. FILES
