tshark (CLI) from wireshark (GUI) {gonna sniff your packets}

there is a wonderful CLI utility tcpdump to handle packet sniffing... but there is also one similar utility with the power of Wireshark at command line known as TSHARK (if you don't know)


so, to use it you just need to install Wireshark in plain old-skool way like

#yum install wireshark

and then to start 'tshark', you need to simply run it like

#tshark

but in some cases, on running '#tshark' if it gives error like 
tshark: error while loading shared libraries: libsmi.so.2: cannot open shared object file: No such file or directory

so, you just need to install one more library, which gets failed to install automatically still required

#yum install libsmi

and then run '#tshark' smoothly
