現場エンジニアの謎解き(学校編)
1.
現場エンジニアの謎解き (学校編) @その辺の人
2.
えんぷらコス is 何?
3.
自己紹介 文教系(学校)インフラエンジニア 民間系のお仕事もやってます
Active Directory & GPOをゴリゴリ Hyper-v RDS(Citrix Xen App) ネットワークもほんのり(L3とかVPN)
4.
勉強会をたまに https://www.facebook.com/NAWATech
5.
中・高の学校現場は基本謎い 機器・ネットワークがほぼ管理されていない あってもメンテナンスされていない
野良でいろんなモノが存在する クライアントは当たり前 いつの間にかサーバー入ってる いつの間にかスイッチ入ってる 機材が新旧オールスター勢ぞろい 10Baseハブ現役、PentiumⅡサーバー現役
6.
根本の問題 先生は年度更新で移動する(平均3~5年毎) 次の担当者への引き継ぎ一切なし(あっても1日)
入札毎に業者が入るので横の連携ほぼなし
7.
で、今年の夏に初めて行った学園 作業内容:PC教室の更新
8.
9.
で、この学園 案の定、機器・ネットワークの台帳なし LANケーブル挿す度にセグメントが変わる
どうも調べたらゲートウェイが3つ存在 印刷室でL3スイッチ発見、でも設定資料がない
10.
心境
11.
どうしたか 野良DHCPの調査 物理配線の行き先&GW装置をとにかく探す
L3スイッチの中身を抜き出し 納品書から業者調べ&電話で聞き込み ⇒とりあえず学園内を可視化 で、本来の作業
12.
まとめ 現場サバイブする能力は養われる っていうか無いと死ぬ いろいろ探索
& クエストが毎回発生 慣れると楽しい たぶん楽しい_(:3」∠)_
