The FreeBSD Project is excited to take part in the Google Summer of Code 2005. This project endeavors to fund students to contribute to an open source project over the summer break.
With SCSI disks, you don't have the same performance problem that you do with ATA disks doing tagged queueing (or not), because:
1. All modern SCSI disks can do tagged queueing.
2. With SCSI disks, the status phase is completely decoupled from the data phase. There is no ordering constraint. Since a tag number comes along with the status, the controller knows which command completed. 0751動け動けウゴウゴ２ちゃんねる2005/06/17(金) 01:58:49ID:mundipDW0 確かにはいってるにははいってるんだけど、SCSIほど深くないのですよね。＞キュー そーすは忘れた。 0752root▲ ★NGNG>>751 その後質雑のほうでいろいろと情報を教えてもらいました。 どうも、そういうことみたいですね。

ServerTokens Minimal ServerSignature Off 0767動け動けウゴウゴ２ちゃんねる2005/06/23(木) 22:03:24ID:LCKfhbrS0 個人的な意見だけどFreeBSDでports使いならServerSignatureなんて隠さなくてもOk Gentooを含めたありとあらゆるOSの中でもportsのcurrentのすばやさはトップクラス だとおもうから。 0768動け動けウゴウゴ２ちゃんねる2005/06/23(木) 22:42:14ID:TXbu4uLA0 確かに（メンテナにもよるが）Portsの更新は早いけど隠さないに越したことはないと思う。 で、ServerTokensはMinorでもいいんでは？ 0769動け動けウゴウゴ２ちゃんねる2005/06/24(金) 01:30:54ID:bXJx3lGS0 まぁ「隠しているから多少セキュリティアップデートが遅くてもいいか」と 油断するという要素さえなければ、そのあたりはどうでもいいことだと思う ので、ポリシーしだいということで。 0770 ◆Reffi/bQ.c ＠ｒｅｆｆｉ@報告人 ★2005/06/24(金) 02:30:09ID:???0 Problem Report amd64/82555: Kernel Panic - after i connect to my "amd64" from another network bsd box [ssh session].

20050624: AFFECTS: users of lang/perl5.8 AUTHOR: tobez@FreeBSD.org
lang/perl5.8 has been updated to 5.8.7. You should update everything depending on perl. The easiest way to do that is to use perl-after-upgrade script supplied with lang/perl5.8. Please see its manual page for details. 0782root▲ ★NGNG あと、これも影響あり。

ProFTPd binary moved from ${PREFIX}/libexec to ${PREFIX}/sbin. People using proftpd with inetd must use ${PREFIX}/sbin/in.proftpd (or ${PREFIX}/sbin/proftpd which is just the same).
