AFAIK there is _always_ the initial agent -> server communication before any calls. This is trivial to detect. On 10/24/06, Andrew Hay <andrewsmhay () gmail com> wrote:
Has anyone, in practice...not in theory, been able to create and validate a snort signature that is able to classify Skype traffic? I've been researching for days and am having a hard time. I know that TippingPoint has a way of classifying (and blocking) Skype traffic but from what I hear they don't appear to be sharing the 'secret sauce'. Any input would be greatly appreciated. -- Andrew Hay [NSA/CCSE Plus/CCNA/Security+/RHCE/GCIA/SSP-MPA/SSP-CNSA] blog: https://www.andrewhay.ca email: andrewsmhay || at || gmail.com ------------------------------------------------------------------------- Using Tomcat but need to do more?
