Topic: additional lan adapter

[Stefano]

hi all

I have a SME 7.3 running as a guest on an ESX machine.. I have no control on ESX..

SME is setup as server only..

for backup purpose, sysadmin has connected a nas on the second physical lan adapter of ESX host, added an second virtual lan adapter on each virtual machine and told us to use it to store backup.

10.0.0.X/8 is internal lan, currently used by SME and all the other servers and clients
192.168.1.X/24 is the secondary lan for virtual servers and nas only for backup purpose.

I'm in the need of configure eth1 and make its setup persistent..

the script I'm using to backup is something like

Code: [Select]

ifup eth1
mount //nas_storage /my_mount_point
do backup into my_mount_point
umount
ifdown eth1

all is working fine, but each time I run the signal-event post-upgrade command I loose my ifcfg-eth1 file.

I've already tried to create a template in /etc/e-smth/templates-custom/etc/sysconfig/networks-scripts/ifcfg-eth1/ but without success.

any hint?

what's the SME's way to achieve this setup?

TIA

The post-upgrade event does not expand this template fragment directly.  Access the directory templates2expand in the post upgrade event and add your fragment there.

Hi Greg..

do you mean I have to put my template directly into /etc/e-smith/events/post-upgrade/templates2expand?

thanks

Hi Greg..

It is even easier than that.  Simply create an empty file in templates2expand representing the configuration file you want to expand templates for.  For example: touch ~/templates2expand/etc/sysconfig/networkscripts/ifcfg-eth0.  Of course, you'll very likely need to create the directory where the config file lives in templates2expand first.

No, you do not have that need. Someone just needs to configure a router between 10.0.0.X/8 and 192.168.1.X/24. Or if such a router already exists, you just need to use the local networks panel so that SME server knows about the router.

@Charlie: do you know if such a setup is possible on ESX?

I mean.. ESX physical server has 2 lan adapter, each one has been associated with different virtual network.. could be this router a virtual one?

TIA

I'd be very surprised if it was not, but I don't use ESX so I don't know. [Google suggests esxcfg-route might be useful to you.]
