RSpecでテストする際に、「Warning: you should require 'minitest/autorun' instead. Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'」と警告された。

Ubuntu14.04にCCNXをインストールする
Installing CCNxに書いてあるものをすべてインストール
$ sudo apt-get install autoconf libssl-dev libexpat-dev libpcap-dev libecryptfs0 libxml2-utils automake gawk gcc g++ git-core pkg-config libpcre3-dev openjdk-6-jre-lib
実行結果残ってないけど確か、
E: Sub-process /usr/bin/dpkg returned an error code (1)
とか
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
とかちょくちょくエラーが出てた気がするけど気にせずに進む(ぐぐって色々試したけど改善されなかった)。
その後、ccnx-0.8.2のフォルダに移動して、
$ ./configure $ make $ make test $ make install
で完了。
VLCをインストール
$ apt-get install vlc libvlc-dev
を実行する。
その後terminalでvlcを実行して($ vlc)VLC media playerが立ち上げればOK。
/ccnx-0.8.1/apps/vlcに移動し、その中にあるMakefile.LinuxをMakefileという名前に変更する。
その後、
$ make
すると、libaccess_ccn_plugin.o、libaccess_ccn_plugin.soという2つのファイルが/vlc内に入っている。
が、makeしてもエラーが出る。
解決方法
まず、Synaptic Package ManagerをSoftware Centerから入手。
その後起動し、検索欄に"libvlccore-dev"と入力しこれをインストール。
もう一度makeするとちゃんと通る。
$ sudo make install
でおしまい。

Terminal、bash、zshの設定の際に参考にしたサイトまとめ
WiresharkのTSharkを使いパケットキャプチャ
* <div style="padding:4px 5px;border-color:#f1c40f;border-width:0 0 0 6px;border-style:solid;">TSarkについて勉強</div>
ネットワーク分析の授業でTCPDUMP or Wiresharkを使って、パケットキャプチャデータを収集するというものがあったので、今後も使うことになりそうだしその際に参考にしたサイトのまとめ。自分はWiresharkのコマンドラインで実行する版のTSharkを使用した。
・WireSharkの裏技 〜 コマンドラインで実行できる「TShark」 〜
・パケットキャプチャ術で秘密もちょっぴりこぼれた？ (1/5)
・Wireshark Display Filter Reference: Frame
・Export pcap data to csv: timestamp, bytes, uplink/downlink, extra info
上4つが特に参考になった気がする。
* <div style="padding:4px 5px;border-color:#f1c40f;border-width:0 0 0 6px;border-style:solid;">実際にターミナルで実行したコマンド</div>
>|zsh|
% tshark -D
1. en0 (Wi-Fi)
2. p2p0
3. en4 (Thunderbolt 1)
4. lo0 (Loopback)
||<
これでこのPCに備わっているNICの一覧が表示さる。
>|zsh|
% tshark -i 1 -a duration:3600 -w homework.pcap
||<
「1」というのは先のコマンドでのNICの番号に対応している。
「-a duration:3600」で3600秒=1時間たったらキャプチャをやめる事ができる。
「-w homework.pcap」でhomework.pacpにキャプチャしたものを保存する。
>|zsh|
% tshark -r homework.pcap -T fields -e frame.number -e frame.time -e frame.len -e frame.protocols > homework.csv
||<
課題では.pcapファイルを.csvに変換し、グラフを作成する必要があったのでこのように変換した。
frame.numberはフレームのNo
frame.timeは年/月/日/時、分、秒/経過時間
frame.lenはパケットのサイズ
frame.protocolsはプロトコル
を表している。
実際にWiresharkのように、経過時間のみを表示したいときは、
frame.time_relativeを使用すれば良い。
詳しいことは上から3つ目の記事を参考になります。
* <div style="padding:4px 5px;border-color:#f1c40f;border-width:0 0 0 6px;border-style:solid;">P.S</div>
有名なアプリケーションなのになぜWiresharkはこんなにもださいデザインなのか。ということで「Wireshark ださい」で検索したらこんな記事が出てきた。一部引用する。 ネットワークパケットを収集分析するWireShark
>>
この世とは思えないほどのださいデザインの画面が開きますが壊れているわけではありませんし、レスキューモードになっているわけでもありません。エンジニアとはこれぐらいのデザインでちょうど良いのです。

そんなものなのだろうか…？(笑)
ウインドウの幅くらい変えられるようにして欲しいなあ…。
