Surebackup - linux proxy

[frankive]

I use SureBackup a lot and everything works like exptected.
But today I want to do some softwaretesting on a linuxserver so i create a new application grou p and virtual lab and also choose "use proxy for internet access port 8080".
In the linux terminal i try to run " export http_proxy=http://192.168.98.2:8080 " but I still cant ping 8.8.8.8
192.168.98,2 is the gateway in production for the linuxserver and it respond to the ping (192.168.98.2 is the proxy in the lab)

What am i missing here?

must be some linuxgurus here?

Question for you. Is the Veeam Virtual Proxy picking up a DHCP address on the production-facing interface or is it static. Also, which version of B&R is this v7 or v8?

[frankive]

The interface is DHCP. It is version 8, with latest patch.
I can confirm the proxy is working since if I use a windows vm and enable proxy in internet explorer it is working as exptected.

One thing you're missing is that setting the HTTP proxy doesn't have anything to do with being able to ping. Ping happens at a much different level in the IP stack while HTTP proxy happens at the application level. By setting this environment your telling any application that honors this environment setting to send all of it's HTTP requests to the proxy rather than directly to the servers in question. Setting this won't allow you to ping since ping isn't HTTP.

If the application also uses SSL/TLS you'll likely need to also set the https_proxy environment:

Code: Select all

export http_proxy=http://192.168.98.2:8080
export https_proxy=$http_proxy

Also, remember that setting the environment variables impact only your specific session unless you change them in the global environment. There are also some application that simply don't honor these options and instead require you to set proxies via their own config.

But no matter what, you probably won't be able to ping, because these settings don't impact ping.

Tom, you could have simply said that ICMP and TCP are two different protocols even if they both use IP as their transport, and HTTP uses TCP

I will try to do dig some more into the apt-get environment to see if I can proxy that traffic through the virtual lab proxy
I will post the results as soon as I have them.

Merry Christmas!
