Hello, Thanks for the response. I have to write an application where I have to send icmp pings when I receive certain data in my eCap adapter. But I am stuck at this issue and not able to move forward. I am running squid with cache_effective_user root. What else I would have to do to be able to open socket in my eCap adapter.
