*nix split eth interfaces

[phishphreek]

Hi all!

I have a RH9 server that I've setup for several different purposes. I use it as a workstation and also as a server. Mostly it is my media server. I have ripped almost every single CD that I have to the hard drive and offer it to everyone on my home lan. (watch out RIAA!!... just cause I didn't want to keep loosing my CDs cause my brother is an idiot...) I also have some video and etc. I house my intranet page which I use only for myself for access to my ebooks from work and school. I have ssh setup so I can use VNC and have remote access.

With all that said... I have two interfaces.

For some reason, I can't get traffic from one service to go over one specific interface.

Example:

I'm transftering data over smb (samba) and I'm also downloading up2date packages.

When I do an "iptraf" and look at which interfaces are being used... only eth0 is in use.

How can I make certain services go over specific interfaces.

Ideal setup... at the moment.

eth0 for

web
remote desktop (ssh/vnc)
misc web programs

eth1 for

samba (file/print)

The reason I want to change it up is so I can get the maximum amount of data over each interface. Since I'm downloading updates, my file tranfers are slower (though not much).

Is this possible?

I haven't found too much info in regards to this. Mostly using two interfaces for a firewall/internet connection sharing/etc.

Any advise or opinions are (as usual) greatly appreciated!
Thanks in advance!

Something similar to the first section below should be in your smb.conf file

# This option is important for security. It allows you to restrict
# connections to machines which are on your local network. The
# following example restricts access to two C class networks and
# the "loopback" interface. For more examples of the syntax see
# the smb.conf man page
hosts allow = 192.168.1. 127.

For some reason some smb.conf files neglect the following:
-------------------------------------------------------------------------------------------------
# Configure Samba to use multiple interfaces
# If you have multiple network interfaces then you must list them
# here. See the man page for details.
interfaces = {IP/netmask of eth1 }

bind interfaces only = True
-------------------------------------------------------------------------------------------------
( that would be the man pages of smb.conf )

Good firewall rules should take care of the rest.

Was this what you were looking for ??

Ah, Ok. I remember seeing the interfaces in the smb.conf file.... now.
I was a bit buzzed last night when I wrote that... (my sisters 21st bday and she got engaged in the same day!)

Is there any way to make the other services use a specific interface?

I know that I can just config smb to use a separate interface and that'll take care of what I want to do... but for future reference.

Anywho.. thanks for the smb.conf info!

Heya Phishy.

With SSH, I have it listening on a specific IP on a number of dual homed boxes.

Browse to /etc/ssh and edit sshd_config.

You'll see a section like so:

#Port 22
#Protocol 2,1
#ListenAddress 0.0.0.0
#ListenAddress ::

Just specify the addy you want here. If ya need step by step NFO, PM me and I'll send you a copy of my conf file.

Thanks horsey!

I haven't had a chance to pull apart the conf files for every service yet. Guess this would be a good time to do that. I normally browse through them pretty quickly and mod a few settings... but thats about it.

Thanks for the advise on the ssh service.

I appreciate it!
