我有使用nmap的“((22-'Invalid arguments')')”。 我用谷歌搜索了https://seclists.org/nmap-dev/ 但是关于它,当我使用此错误时,它谈论的是IPv6 IPv4在任何地方都没有提及IPv4,为什么我会得到 这个奇怪的错误吗?
我输入了
nmap --send-eth --release-memory --nsock-engine=epoll --allports --fuzzy
--randomize-hosts --log-errors --max-os-tries=9 -n --reason --append-output
--scanflags=URGACKPSHRSTSYNFIN --max-retries=6 --host-timeout=225s
--stats-every=10m --ttl=255 --min-hostgroup=5 --max-hostgroup=25
--max-rtt-timeout=60s --scan-delay=250ms --max-scan-delay=25s
--stats-every=1 -v5 -sT -sV -A -p 80-82 0.18.0.0
得到了:

尝试较少争论时nmap -p 80-82 0.18.0.0

尝试使用ncat时,我得到了:
marc@platinum:~/NCat_test$ nc -vvv 0.18.0.0 80
0.18.0.0: inverse host lookup failed: Unknown host
(UNKNOWN) [0.18.0.0] 80 (http) : Invalid argument
sent 0, rcvd 0
marc@platinum:~/NCat_test$ nc -vvv 0.18.0.0 81
0.18.0.0: inverse host lookup failed: Unknown host
(UNKNOWN) [0.18.0.0] 81 (hosts2-ns) : Invalid argument
sent 0, rcvd 0
我仍然有“无效的论据”,但是这次不是22,而是获得了帖子编号和服务
80(http) 81(hosts2-ns)
这引发了一些问题
1)ncat和nmap的“无效参数”是否与同一件事相关?
2)我如何使nmap信息化而不是打印22?
3)我怎么能说由于防火墙而使远程端口真正关闭或真正打开并拒绝?
感谢您的帮助

0.0.0.0/8
网络中的IP地址(第一个位置带有0
的任何地址)保留为“当前网络”,仅作为源地址有效。 Nmap通常倾向于不禁止诸如无效地址或端口号之类的异常事件(大多数实现中类似地保留端口0),因为当您违反约定时会发生有趣的事情。但是,当Nmap调用系统的网络功能时,它们可能会产生这样的错误。
