Trying to run Dachstein v1.0.2-1680
On boot, system recognizes and finds NICs
Receives DHCP configuration from Shaw cable service
On boot, get message:
Starting interface: eth1: unable to get IRQ 10
SIOCSIFFLAGS: Resource temporarily unavailable
eht1
When trying to ping internal network,
system uses eth0 instead of eth1
Any idea what I am doing wrong?
Thanks in advance,
Demian Marshall
The system:
AST Cyrix Cx486 DX2/66
20M ram
Three ISA slots
The NICs:
Intel Etherexpress pro io=0x300 IRQ=10
(eth0: connected to cable modem)
D Link DE220p io=0x320 IRQ=11
(eth1: connected to private network)

# Brief instructions for this file
########################################################################
#######
#
# VERBOSE=(YES/NO) Default: Yes
# Be verbose about settings.
#
# MAX_LOOP=(int) Default: 10
# Maximum number of incrementable entries to search for.
# IE: If you create a DNS7=, and MAX_LOOP=7, it will not be reached.
# (DNS0 - DNS7 == 8 entires)
# Setting this value too high will decrease the speed of the
configuation
# system.
#
# IPFWDING_KERNEL=(YES/NO/FILTER_ON) Default: NO
# Enable IP forwarding in the kernel. FILTER_ON means forwarding will
# only happen when IP filtering rules are loaded
#
# IPALWAYSDEFRAG_KERNEL=(YES/NO) Default: NO
# Enable IP Global defragmentation in the kernel.
#
# **WARNING** - If this was turned on everywhere in a network of
routers,
# it can result in TCP connections failing and TCP connection resets.
#
# ONLY turn this on if the box is a firewall or the single point of
# entry for a network, or an endpoint for port forwarding or a load
# balancer for a WWW server farm. DO NOT turn this on if the box is a
# conventional router as it breaks the TCP/IP RFCes. This option is
# needed when using IP NAT, IP masquerading, IP autofw, IP portfw,
# transperent proxying or other kernel operations that intercept a
# packet flow and redirect it.
#
# It is a usful tool when using a packet filtering router to protect
# directly attached ethernet networks of servers as it stops fragment
# attacks on the servers in behind the router. Another use is packet
# filtering router to protect dial-in Internet users on NASes
# (Portmasters, TC racks etc) from various SMB and fragment attacks
# and to redirect all WWW connections into a WWW proxy-caching server.
#
# CONFIG_HOSTNAME=(YES/NO) Default: NO
# Create /etc/hostname file using HOSTNAME entry.
# Any current hostname file will be **OVERWRITTEN**
#
# CONFIG_HOSTSFILE=(YES/NO) Default: NO
# Create /etc/hosts file using HOSTSx entries.
# Any current hosts file will be **OVERWRITTEN**
#
# CONFIG_DNS=(YES/NO) Default: NO
# Create /etc/resolv.conf file using DOMAINS and DNSx entries.
# Any current resolv.conf file will be **OVERWRITTEN**
#
# IF_LIST Default: "$IF_AUTO"
# A space seperated list of interfaces that can be ACTIVE on this
machine
# This controls which interfaces can be brought up and down manually.
#
# IF_AUTO Default: "eth0"
# A space seperated list of interfaces that get started on boot.
Tunneling
# interfaces like CIPE should be after the raw interfaces they depend
on.
# The interfaces are started in the order they occur on the list, and
are
# shutdown in the reverse order of IF_LIST.
#
# IPFILTER_SWITCH=(none|router|firewall) Default: "none"
# Selects the basic IP filtering/firewalling setup of the router.
"None"
# is used for a straight through router, "router" for a filtering router
with
# IP spoof protection and Martian protection and "firewall" for a basic
IP
# masquerading/NAT firewall. The basic filter types are provided in
# /etc/ipfilter.conf. If you want more than what is provided read the
man
# pages for ipchains or ipfwadm and BE CAREFUL when you edit this!
