If you have built VTA from the source files, please go to next topic   Using VTA
 

Configuring VTA under LINUX

The following steps are required before you run VTA binary image:

1. Enter vta-1.0/vta directory, su root, chown root pcap, chmod 4111 pcap (to make it a root setuid program ). This step is not required if you are only using VTA to read an existing traffic dump file from local disk.

2. chmod a+x getSock. This is to let every user to be able to run getSock binary. This step does not need root access.

3. Set the VTAPATH to the vta-1.0 directory path. For example, assume vta-1.0 directory is in /home/john/. Then on tcsh, you can use this command to set the VTAPATH:

setenv VTAPATH /home/john/vta-1.0

If you don't set VTAPATH correctly, you will not be able to launch the packet capturing program successfully.

4. In vta-1.0/vta directory, type in ./vta to run VTA.
