Operating Systems Linux Red Hat Centos 4 32 bit - New kernel ethX MAC address order issue Post 302605357 by Corona688 on Wednesday 7th of March 2012 10:01:10 AM

It can be difficult to force a device into being eth0 when there's already another eth0. For this reason, when I need to force ethernet adapters into a specific order, I name them other things -- 'wan' or 'lan0' for instance.

When -- not if -- something new autodefaults to eth0, it won't "eat" the names you're using, making the order you want impossible from the get-go.

SHOREWALL-MACLIST(5)						  [FIXME: manual]					      SHOREWALL-MACLIST(5)

NAME
maclist - Shorewall MAC Verification file SYNOPSIS
/etc/shorewall/maclist DESCRIPTION
This file is used to define the MAC addresses and optionally their associated IP addresses to be allowed to use the specified interface. The feature is enabled by using the maclist option in the shorewall-interfaces[1](5) or shorewall-hosts[2](5) configuration file. The columns in the file are as follows (where the column name is followed by a different name in parentheses, the different name is used in the alternate specification syntax). DISPOSITION - {ACCEPT|DROP|REJECT}[:log-level] ACCEPT or DROP (if MACLIST_TABLE=filter in shorewall.conf[3](5), then REJECT is also allowed). If specified, the log-level causes packets matching the rule to be logged at that level. INTERFACE - interface Network interface to a host. MAC - address MAC address of the host -- you do not need to use the Shorewall format for MAC addresses here. If IP ADDRESSESES is supplied then MAC can be supplied as a dash (-) IP ADDRESSES (addresses) - [address[,address]...] Optional - if specified, both the MAC and IP address must match. This column can contain a comma-separated list of host and/or subnet addresses. If your kernel and iptables have iprange match support then IP address ranges are also allowed. Similarly, if your kernel and iptables include ipset support than set names (prefixed by "+") are also allowed. FILES
