[ale] Multi-homed server networking

[Jeff Lightner]

I don't see how bonding would do what he wants.  He wants to separate
traffic - not combine it.

 

What we do for separate traffic (we do it for a backup LAN on GigE
network while primary is on 10/100) is simply assign the IPs to a
different <hostname>b instead of just <hostname>.  The only traffic that
can find other hosts on the backup LAN have to look for it by that
secondary name with the "b" appended.  

 

For example:  hostname = winsuck then the secondary IP would only be
known by winsuckb.   A configuration for Samba expecting shares from
winsuck wouldn't see them from winsuckb even if they were there because
it wouldn't be looking for anything at that name.

What you want to do is enable channel bonding. It's a fairly easy setup
(google 'linux bond0') and make sure your switch supports fast
etherchannel or some other compatible trunking protocol.

I have a series of Linux servers that, for reasons beyond my control,
have only 10/100 Ethernet for connecting to their clients.  Because the
servers are multi-homed, however, I have the option of connecting them
to each other via a 10/100/1000 switch on a private IP range and that's
what I would like to do.  However, I don't want doing so to make this
"backchannel" visible to the client population in an untoward way.

For instance, if one of the servers is a Samba server and Samba
listens/talks over both eth0 and eth1, I don't want machines on either
eth0 or eth1 see the Samba server twice, i.e., once directly and again
"through" the server itself to the other side.  I don't want Windows or
other Samba clients to freak.
