testing remote hosts with different source address
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
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

It's not in the current version, but I do have code for this in the current development version. There is a patch available at http://henrik.hswn.dk/srcaddr.patch - this should apply to the 4.2.2 version:
- save the file to /tmp/srcaddr.patch
- cd xymon-4.2.2
- patch -p0 < /tmp/srcaddr.patch
- make
- cp bbnet/bbtest-net ~xymon/server/bin/
With this patch, you can specify the source address using "@IP" in the test-spec in bb-hosts. E.g.
10.0.0.1 myhost # ftp at 172.16.1.1 ssh
will cause the ftp-test to run with a source-address of 172.16.1.1
It doesn't support specifying the source for http/https tests.
Regards, Henrik
Now that is really cool. Thank you!

I may have misunderstood what was originally asked for but...
I have a Hobbit server that connects to two completely different networks and monitors servers on both those networks. The interfaces on the Hobbit server are 10.0.0.2 and 192.168.10.2.
Servers on the 10.0.0.0/24 network are configured to connect to the Hobbit server at 10.0.0.2 whilst servers in the 192.168.10.0/24 network are configured to connect to the same Hobbit server, only on 192.168.10.2 instead. In this scenario if the Hobbit server config has:
10.0.0.1 my10host # ftp ssh 192.168.10.1 my192host # ftp ssh
When it tests an FTP connection to 10.0.0.1 the network will takes the shortest path and route out of 10.0.0.2. When it tests FTP on 192.168.10.1 routing will send the packets out of the 192.169.10.2 interface. The same for the ssh connection.
Is this not what lchiavacci at netartis.com wanted?

Hello Martin, what I asked for is what Henrik has introduced in the patch he mentioned. I have multiple IP addresses assigned to the same network interface and I cannot use the routing solution that you mention.I would like to use one of these addresses based on the host that I am testing .
I will try the patch that Henrik mentions in his message after upgrading to 4.2.2 version. Thank you all for the replies.
