安裝scapy

pip3 install scapy-python3yum install libffi-devel
pip3 install cryptographyln -s /opt/python/bin/scapy /usr/bin/scapy

安裝完成后運(yùn)行scapy:

[root@localhost ~]# scapy
INFO: Can't load Python libreadline or completerWARNING: No route found for IPv6 destination :: (no default route?). This affects only IPv6
INFO: Please, report issues to http://m.lncdfzh.com.cn/phaethon/scapyWARNING: IPython not available. Using standard Python shell instead.
Welcome to Scapy (3.0.0)>>>

解決Can't load Python libreadline or completer的問(wèn)題：

yum install readline-develyum install patchpip3 install readline

再次運(yùn)行scapy,這時(shí)已經(jīng)支持自動(dòng)補(bǔ)全了:

[root@vnode33 ~]# scapy
WARNING: No route found for IPv6 destination :: (no default route?). This affects only IPv6
