Any suggestions why I'd have two sets of pcap includes? Just thinking about it, I upgraded libpcap this morning from 1.0.0_1 to 1.1.1

Many thanks,
John
 
Remove libpcap and let dsniff use the one that's supplied with the base OS.
 
OK, but seeing as libpcap is needed by tcpdump, won't this cause issues if I remove tcpdump & libpcap, install dsniff and then reinstall tcpdump (along with libpcap)?
 
tcpdump is a base-system utility, so it will use the base system's libpcap:

Code: 
# ldd /usr/sbin/tcpdump
/usr/sbin/tcpdump:
        libpcap.so.7 => /lib/libpcap.so.7 (0x28118000)
        libcrypto.so.6 => /lib/libcrypto.so.6 (0x28145000)
        libc.so.7 => /lib/libc.so.7 (0x28297000)
 
And there I was thinking I needed the tcpdump port as it wasn't in the base system. Removed tcpdump & libpcap, installed dsniff and everything works fine.

Thanks.
