Does it copies actual data in packet? 3)Also can anybody explain me function int ip_build_xmit(struct sock *sk,int getfrag (const void *,char *,unsigned int, unsigned int),const void *frag, unsigned length, struct ipcm_cookie *ipc, struct rtable *rt, int flags) and its parameter usage??? regards, linux_lover __________________________________ Do you Yahoo!?
