Hi, This seems very close to what I was looking for. Thanks. Just one more thing- is there any way of making the LD_PRELOAD associate with socket() calls from only a particular 'pid'. If I set the LD_PRELOAD environment variable for only one shell would it affect the socket calls which are initiated by other programs? I only need to hijack socket calls() emanating from a particular pid. thanks, Ronak Quoting Gilad Ben-Yossef <gilad@codefidence.com>: > > > > Henrik Nordstrom wrote: > > On Thu, 26 Aug 2004, Anupam Kapoor wrote: > > > >> how about limiting the packet through a specific interface via the > >> SO_BINDTODEVICE socket > >> option ? i guess that's what you (henrik) means. right ? > > > > > > That is one way of many.
