I apologize I should have looked closer at this the first time - apparently
I could not either - see date stamps below on these snapshots of the source
code - I was on 7702 when I responded the first time the other day - note
7702 was pulled 5 Min after 7704.

I have since moved up to 7737 - but as I am writing this EMAIL noticed my OS
had crashed - SIE issue - and I noticed in the change log there have been
some changes in this part of the hercules code recently - so I might be
headed back to 7702.

I did - I thought you had gotten further with FC15

Not sure - I started on FC11 and updated it to FC12 in place - skipped FC14
and installed from scratch FC15 - FC15 seems really stable to me have not
had any issues -

Those dates match what I have here from the ISO DVD for FC15 

So I pulled the latest Source code snapshot - 7747 compiled it - and tried
to boot the install images - 
it just loops never getting past - the Linux message - "Trying to unpack
rootfs image as initramfs..."

Went back to 7702 and it came up to the network configuration fine.

I definitely can get that far on 7702

Are you running hercules under Windows or Linux?

It also depends if you are using CTCs - it would be the IP address at the
other end, if you are using LCS devices it should be your router or gateway
to the internet.   LCS Devices are simpler to use on Linux you do not need
to add routes just a change to sysctl.conf to
net.ipv4.conf.default.proxy_arp = 1 

And the Linux guest just appears as another machine on your network - this
setting is for RHEL/Fedora Linux  

Here is the final config - copied from
/etc/sysconfig/network-scripts/ifcfg-eth0 - highlighting the things you will
be prompted for during the install. 

From herc Config 
0740.2 LCS -n /dev/net/tun 192.168.100.121

From FC15 networking config 
DOMAIN="dpcomputersolutions.com"

DNS Server used on your network
IPADDR="192.168.100.121"                                      // IP of

>> Do I have to have the modules for TUN and brothers loaded ( via the
hercules.init script ) in order to get access to anything from FC15 ?

Typically I do not - and Hercules loads everything required from the search
path - so I have nothing in my config using LDMOD 

Hopefully this helps -
