Help with routing question.
Hi James,
Simply remove the GATEWAY line from the eth0:192 interface config :D
Then you'll had only one default gateway. And the source IP to all unknown address
will be the routeable one.
Att.,
Antonio.

Simple routing question
We use a dual homed CentOS-6.3 host for our Internet gateway router.
Its internal nic (eth1) is configured such that the address
192.168.0.1 is one of its aliases.
# cat /etc/sysconfig/network-scripts/ifcfg-eth1:192BOOTPROTO=none
BROADCAST=192.168.255.255
DEVICE=eth1:192
IPADDR=192.168.0.1
IPV6INIT=no
MTU=""
NAME="LAN - Non-routable"
NETMASK=255.255.0.0

Cannot get kvm guests to connect to network
I installed a new CentOS-6.3 kvm guest on a recently provisioned kvm
host also running CentOS-6.3. This guest will not connect to the
network and the host cannot connect to it via its public IP address. I
had previously installed a guest system on thst same kvm host using
the same ISO and that system connects to the network without problem.

OT: RIP settings for private netblocks
I am contemplating converting some of our internal networks from routable
to private IPv4 address space. I have a question about RIP as implemented
under Cisco IOS 12.x.
Presently the setting for rip is:
router rip
version 2
passive-interface [[FastEthernet]]0/0
network aaa.bbb.ccc.0
no auto-summary
What I would like to know is how one routes the entire 192.168/16 address
space using rip.

Vpn Trouble
I am trying shorewall as my previous post With alisias on eth1 loc and 4

The odd thing is when I enter one of the vpns in interfaces such as vpn1 it
works.
But if I enter the vpn in the hosts file shorewall blocks the vpns.

[OT but please read] ORBS blacklisting ns1.samba.org
Some lists and emails are distributed via ns1.samba.org. For those of
you that use ORBS, you'll find it is blacklisted now. There is no
mention of it on the website and it doesn't return a positive when you
enter it for testing but it has slipped into the ORBS blacklist
somewhere.
Samba.org admins may wish to force all ns1 outbound email via another

CentOS-5.4, KVM, QEMU, Virt-Manager and kvm-qemu-img
What is the correct combination of packages to configure and manage
VMs via virt-manager undet CentOS-5.4? If I use qemu then while
virt-manager works I obtain SELinux alerts with respect to the
real-time clock. If instead of qemu I use kvm-qemu-img then
virt-manager simply does not work. It starts but it does not find
any form of qemu and the selection boxes are all greyed out.

Reality check: IPFW sees SSH traffic that sshd does not?
This note is essentially a request for a reality check.
I use IPFW & natd on the box that provides the interface between my home
networks and the Internet; the connection is (static) residential DSL.
I configured IPFW to accept & log all SSH "setup" requests, and use natd
to forward such requests to an internal machine that only accepts public
key authentication; that

CentOS as a router
I am setting up a small CentOS-5.3 host to act as a router. I have
the device configured and working. What I am trying to accomplish
now is configuring the firewall so as to protect both the router and
the LAN.
The host configuration has the WAN attached to eth0 (IP_ADDR = A)
and the LAN attached to eth1 (IP_ADDR = B). The default gateway for
B is A. The default gateway for B is B-1. There

Anonymous SIP calls
We have a FreePBX-12 / Asterisk-12 setup that supports about 24
extensions, most internal Snom870s but six or so external (Jitsi-2.8).
we use TLS and SRTP everywhere on our side of the fence. The server
host is a dedicated atom(tm) box using the FreePBX distro (CentOS-6.x)
and is up-to-date. Registrations require very long random passwords
and registrable devices are further restricted by
