A company I work for has a number of virtual servers with ElasticHosts. They are setup in such a way that eth1 is on a private VLAN connecting them to each other. This is so backups sent between servers are not charged at the same rate as external data transfer.
My understanding of how VLANs and network interfaces work is sketchy at best.
How can I make ssh, rsync, etc. transfer data through the VLAN?
My final solution:
I spent a while trying to figure this out,
For all servers involved, edit /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1 BOOTPROTO=static ONBOOT=yes HWADDR=YOUR_MAC_ADDR IPADDR=192.168.0.100 NETMASK=255.255.255.0
Where HWADDR should already be set and the last octate of IPADDR should be different from each other.
Then run, on all servers
After this the IP addresses specified by IPADDR can be used directly as any other IP address.
