Hi,
I am currently building tcpdump on Ubuntu 10.04 - 03 edition.
$ ./tcpdump -h
tcpdump version 4.4.0-PRE_GIT_2012_05_28
libpcap version 1.0.0
Usage: tcpdump [-aAbdDefhHIKlLnNOpqRStuUvxX] [ -B size ] [ -c count ]
[ -C file_size ] [ -E algo:secret ] [ -F file ] [ -G seconds ]
[ -i interface ] [ -M secret ]
[ -r file ] [ -s snaplen ] [ -T type ] [ -w file ]
[ -W filecount ] [ -y datalinktype ] [ -z command ]
[ -Z user ] [ expression ]
I even tried adding -static flag but I have got errors regarding dlopen and
dlclose. Not sure of exact error but will try again the same.
Regards,
Ajith
