| + | *macosでnmapをつかってみる [#l0657cc7] | ||
| + | **はじめに [#ze3cf5ae] | ||
| + | |||
| + | masscanをネットワークスキャナとして使って見たけれど，TCPのみという制限があるので，UDPにも対応しているnmapを使って見る．Linuxだとnmapはインストールされているような気がするけれど，macには入ってないのでインストールするところから． | ||
| + | |||
| + | **nmapのインストール [#k9256523] | ||
| + | |||
| + | HomeBrewなので難しいことはないです． | ||
| + | まずは情報を確認． | ||
| + | |||
| + | $ brew info nmap🆑 | ||
| + | nmap: stable 7.80 (bottled), HEAD | ||
| + | Port scanning utility for large networks | ||
| + | https://nmap.org/ | ||
| + | Conflicts with: | ||
| + | ndiff (because both install `ndiff` binaries) | ||
| + | Not installed | ||
| + | From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/nmap.rb | ||
| + | ==> Dependencies | ||
| + | Required: openssl@1.1 ✔ | ||
| + | ==> Options | ||
| + | --HEAD | ||

| + | build-error: 0 (30 days) | ||
| + | $ | ||
| + | 現在のバージョンは7.80とのこと．次にインストール． | ||
| + | |||

| + | **nmapを使ってローカルマシンをスキャンする [#la85b162] | ||
| + | |||
| + | まずは，自分自身をスキャンして見る． | ||
| + | |||
| + | $ /usr/local/bin/nmap 192.168.20.32🆑 | ||
| + | Starting Nmap 7.80 ( https://nmap.org ) at 2019-11-26 18:44 JST | ||
| + | Nmap scan report for 192.168.20.32 | ||
| + | Host is up (0.00017s latency). | ||
| + | Not shown: 969 closed ports, 30 filtered ports | ||
| + | PORT STATE SERVICE | ||
| + | 3283/tcp open netassistant🈁 | ||
| + | |||
| + | Nmap done: 1 IP address (1 host up) scanned in 5.45 seconds | ||
| + | $ | ||
| + | |||
| + | 5秒で完了．masscanより速いなぁ．デフォルトでスキャンする対象ポートが違う野田ロイと想像． | ||
| + | 空いているポートについて，今回の場合3283ポートがnetassistantが使っているという風に，masscanより情報が多いのは好印象． | ||
| + | |||
| + | **nmapでポートとプロトコルを指定してスキャン [#jbaad294] | ||
| + | |||
| + | 次にプロトコルをTCP限定，ポートを1から1024までのwelknownポートのみで，別のマシンをスキャンしてみる． | ||
| + | |||
| + | $ /usr/local/bin/nmap -sT -p 1-1024 192.168.20.30 | ||
| + | Starting Nmap 7.80 ( https://nmap.org ) at 2019-11-26 18:50 JST | ||

| + | |||
| + | Nmap done: 1 IP address (1 host up) scanned in 5.46 seconds | ||
| + | $ | ||
| + | |||
| + | この結果も5.46なので，nmapのポートを指定しない場合のスキャンはこのパターンでしょう．マニュアルを見ないで言っているけど．．． | ||
| + | |||
| + | **全ポートスキャンを１台のマシンに対して実行して見る [#l7a0c8c8] | ||
| + | |||
| + | ウェルノウンポートだけだと5秒強で終わりましたが，全ポートで実行するとどうなるか． | ||
| + | |||
| + | $ /usr/local/bin/nmap -sT -p 1-65535 192.168.20.30🆑 | ||

| + | $ | ||
| + | |||
| + | 約688秒なので11分程度ですね．ちょっとわからないものもたくさん出てきましたが，ちなみこのスキャン対象マシンはmacOS 10.14(Mojave)です． | ||
| + | ちなみに，Windows 10のマシン（Surface Pro 2）にスキャンして見ました． | ||
| + | |||
| + | $ /usr/local/bin/nmap -sT -p 1-65535 192.168.20.149🆑 | ||
| + | Starting Nmap 7.80 ( https://nmap.org ) at 2019-11-26 19:14 JST | ||
| + | Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn | ||
| + | Nmap done: 1 IP address (0 hosts up) scanned in 3.05 seconds | ||
| + | $ | ||
| + | これはWindows Firewallが稼働しているから，速攻で拒否されています． | ||
| + | ping(ICMP)も通りません． | ||

| + | $ | ||
| + | |||
| + | **スキャン相手のFirewall有無を調べる [#qc9d3a78] | ||
| + | |||
| + | オプションに-sAをつけると，ファイアウォールの有無を調べられるというので，実行して見る． | ||
| + | まずは，先に検査してFirewallが稼働してないことが明らかなmacOSを対象に． | ||
| + | |||
| + | $ nmap -sA 192.168.20.32🆑 | ||
| + | Starting Nmap 7.80 ( https://nmap.org ) at 2019-11-26 19:03 JST | ||
| + | Nmap scan report for 192.168.20.32 | ||
| + | Host is up (0.000047s latency). | ||
| + | All 1000 scanned ports on 192.168.20.32 are unfiltered🈁 | ||
| + | |||
| + | Nmap done: 1 IP address (1 host up) scanned in 9.71 seconds | ||
| + | $ | ||
| + | unfilteredとでているので，フィルタ＝ファイアウォールでブロックされてないと判断されている．1000個のポートをスキャンしているとあるけれど，1-1024のウェルノウンポートで5秒強だったのが10秒近くかかっているので，より代表的なポートを使ってスキャンしていると思われる． | ||
| + | そして次に，Windows 10のマシンをスキャンしてみる． | ||
| + | |||
| + | $ nmap -sA 192.168.20.149🆑 | ||
| + | Starting Nmap 7.80 ( https://nmap.org ) at 2019-11-26 19:08 JST | ||

| + | |||
| + | Nmap done: 1 IP address (1 host up) scanned in 98.21 seconds | ||
| + | $ | ||
| + | 今回はfilteredとでた．100秒近くかかっている． | ||
| + | |||
| + | **nmapを使って対象マシンのOSを調べる [#k0f39171] | ||
| + | |||
| + | TCP/IPの通信において，RFCとかで規定されているけれどOSによってやっぱり手順に特徴があったりとかで，その違いを観察すればOSの違いがわかると聞いたことがある． | ||
| + | nmapのオプションで-O(オー)を使うとOSがわかるというので実行して見た． | ||
| + | |||
| + | まずは，macOS 10.14(Mojave)のマシンを． | ||

| + | 推測するにWindows XP SP2らしい．Firewallで通信が止められているので，判明できる情報からはそうなるのだろうなぁ．逆にいうとTCP/IPスタックはその頃から変わってないと言えるでかな． | ||
