You could also use iptables to do source address translation. We do that in some cases where the hobbit server's default source address is not member of a VPN, but another interface's IP is.

Hello Geoff,

Thanks for the idea but I have multiple IP addresses on the same network interface and I would like to send packets from the Hobbitmon server with a different source address for different servers in the bb-hosts file.

Maybe what I am trying to do is not possible with the current version.

Not the same but couldn't you just use different routes on the Hobbit box to get it to go out different interfaces? i.e. 192.168.1.1 to gw of interface1 IP, and 192.168.2.1 to gw of interface2 IP

Hello everyone, I am using Hobbitmon 4.2 and I would like to set up a system with multiple IP addresses on network interface so that I can perform test to some hosts through an IP address and other tests through another IP address, and so on with multiple address aliases.

The hobbitping has a --source option but bbtest-net does not.

I have thought of using the LOCATION tag in bb-hosts and have multiple instances of bbtest-net in hobbitlaunch.cfg but I do not find a way to have packets exit from the system with a different source address for all TCP tests as well as ping.

Has anyone ever done such a setup?

thank you. Lorenzo Chiavacci
