Yes, you have to be root. Or, to quote the fine man page (note the "Under Linux" section): ----- DESCRIPTION Tcpdump prints out the headers of packets on a network interface that match the boolean expression. Under SunOS with nit or bpf: To run tcpdump you must have read access to /dev/nit or /dev/bpf*. Under Solaris with dlpi: You must have read/write access to the network pseudo device, e.g. /dev/le. Under HP-UX with dlpi: You must be root or it must be installed setuid to root. Under IRIX with snoop: You must be root or it must be installed setuid to root. Under Linux: You must be root or it must be installed setuid to root. Under Ultrix and Digital UNIX: Once the super-user has enabled promiscuous- mode operation using pfconfig(8), any user may run tcp- dump. Under BSD: You must have read access to /dev/bpf*. ----- -- Steve On Wed, 26 Feb 2003, Jeff Wong jwong-at-high-tower.com |TCPdump Workers| wrote:
Hello, I am running on a linux system. I am trying to execute the command pcap_open_live and I'm getting the error socket: Operation not permitted in my errorbuffer. I am running as a regular user and I'm not sure if I have to be root instead.
