- [[ネットワーク空間>./ネットワーク空間]]
- [[構成>./構成]]
** 特徴 [#summary]
- コントロールパネル画面から、コンソールリダイレクションの機能が備わっており、GRUB、Linuxのコンソールが取れる
-- Firewall の設定をミスした場合や、トラブル発生時、コンソール画面を取得することが出来る。
-- ''コピペも可能''
- sit0といった、トンネルデバイスの作成が可能
-- IPv6トンネルの作成が可能
- swapファイルの作成が可能
- 生のCentOS5.5 64bit版
- KVMをつかった仮想化
- IPv4のみ
-- 59.106.172.0/23
-- ルータ(Defaultgateway)は、Brocade、VRRPを実装
-- IPv6は初期値で有効
-- IPv6トンネル作成可能
- CentOS5.5 64bit
-- LANG="C" <- 結構重要!
- ntpは本来CentOSの最小構成ではインストールされていないが、別途インストール及び設定済:)
''今後個人的に提供して貰いたい物''
- IPv6ネットワーク及びv6のDNS権限委譲
- IPv4逆引き
-- メールベースではなく申請フォームみたいなのも併せて。
- 今後FreeBSD等も対応予定とのことだが、Ubuntsu, Debian も載せて欲しいという要望もあり
- メモリ、swapの使用量も、コントロールパネルに表示して欲しい
''微妙な内容''
- anaconda のログは消しましょう
- yum レポジトリは、専用サーバと同じように設定して欲しかったな
- VPSのコンパネ
-- UIがリセットしかないので、わかりやすい表記 &br; 状況に応じて、リセット/電源ONに切り替わる若しくは各操作として、ボタンの配置を行う等
-- トラフィックログが100Mbpsが上限で表示される
** ハードウェアスペック [#hwinfo]
- Intel(R) Core(TM)2 Duo CPU T7700 @ 2.40GHz (2Core)
- MEM 512MB
- SWAP 2GB
- HDD 20GB
概要(仮想化環境で見えるところを抜粋)
※ qemu でエミュレートしたCPUがT7700の可能性もあるので、%%実態のCPUは分かりません。%% [[QuadCore の Xeonのようです:http://twitter.com/kunihirotanaka/status/18593480844]]。
ハードウェアについては、[[富士通のPRIMERGY:http://twitter.com/kunihirotanaka/status/18601936314]]を使用しており、現在、www101v.sakura.ne.jp 〜 www118v.sakura.ne.jp の計18台稼働していると思われます。arpを見る限り、00:22:4D 及び 00:40:D0 のOUIを確認することができ、MITAC(TYAN)のベンダを確認することが出来ます。尚、backup1v.sakura.ad.jp (59.106.172.3) はバックアップ用?でSuperMicroのOUIを確認することが出来ました。

SAKURAは確か、出荷時にSAKURAのレポジトリを使用するように出荷されていたケースが多かったのですが、今回はその設定はされていませんでした。クローズベータテストだからでしょうか。

サブネットが、/23 となっているので、512台ほど詰めれることが出来る。
少なくとも今回、/23を着ると言うことは、モニタについては、256台を超えるという事が考えられる。~
現在の申込みは300を超えたそうだ(15日 18:00頃の情報)
*** ルータ [#router_vrrp]
# tcpdump -i eth0 not src port 22 and not dst port 22
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
IP 59.106.172.1 > VRRP.MCAST.NET: VRRPv2, Advertisement, vrid 111, prio 255, authtype simple, intvl 1s, length 20
ゲートウェイのルータはVRRPで実装。

? (59.106.172.2) at 00:04:80:EC:CB:24 [ether] on eth0
172.1 はVRRPなので、実態アドレスではないため、実態と思われる172.2 のIPを見ると、
000480 (base 16) Brocade Communications Systems, Inc
となっていることから、ルータはBrocadeを使用されていると思われる。

見ての通り、MacAddressの最後の4桁及びホスト名が一致しており、且つ、最後にuという名前がついている。
上記の事から、
fe80::5054:ff:fe00:1001: www1001u.sakura.ne.jp
fe80::5054:ff:fe00:1002: www1002u.sakura.ne.jp
fe80::5054:ff:fe00:1009: www1009u.sakura.ne.jp
…
というのが分かり、更にnslookupすれば、v4アドレスも分かる。~
って、v6は現時点でデフォルトで提供されていないので、NETWORKING_IPV6=no にしたらいいのに、と思った。~
若しくは一意性の無い名前など。
