FreeBSD12　qjailでジャンボフレームの設定とLR-LINK製のNIC「LREC6860BT」による作動

Last updated at Posted at 2019-05-26

はじめに

qjailでジャンボフレームの設定の方法が分からず、トライ・アンド・エラーでqjailの設定ファイルを手動で設定し可能になった。今回報告する方法は、なんの根拠もなく、また問題が潜んでいる可能性がある。本来のやり方があってドキュメントの見落としをしてるかもしれなく、わかる方教示いただければと思います。
次に、LREC6860BTは以下の報告で熱の問題がありましたが、解消でき今回のジャンボフレーム設定を行った。しかし、問題が発生し解決に至らなく、その内容を報告する。結果としてbridge接続で使用できない（単独での使用は可能）ので、windowsで使用していたintelのX540-T1と交換することにした。

qjailでジャンボフレームの設定

「FreeBSD 12で自宅サーバの構築　基本システム編その３」で以下のように簡単に設定ファイルを作成できた（インタフェースを機器に合わせem0からre0に変更）。

# qjail create -4 192.168.1.41 jail1
Successfully created  jail1
# qjail config -w re0 -v none jail1
Successfully enabled vnet.interface for jail1
Successfully enabled vnet for jail1

この場合re0に"mtu 9014"のようにジャンボフレームを設定するとepair1aとブリッジ接続するときにエラーが発生する。epair1aに"mtu 9014"が設定できれば問題ないと思われる。
そこで考えたのが、予めブリッジ接続をしてからqjail startすることにする

手動でブリッジ接続設定

rc.confを設定する

/etc/rc.conf
cloned_interfaces="epair0 epair1 bridge0"
ifconfig_epair0a="up mtu 9014"
ifconfig_epair1a="up mtu 9014"
ifconfig_re0="up mtu 9014"
ifconfig_bridge0="addm re0 addm epair0a addm epair1a up mtu 9014"
ifconfig_bridge0_alias0="inet 192.168.1.31/24"

この設定で立ち上げると以下が確認できる

# ifconfig

qjailの設定

qjailの設定がよく分からず、トライ・アンド・エラーで結果以下で落ち着いた。

/usr/local/etc/qjail.config/jqil1
jail1 {
allow.sysvipc       =  "1";
host.hostname       =  "jail1.example.jp";

確認

以下のようにqjailを開始すると２つのjailは正常に作動する。
rc.confでqjail_enable="YES"と設定することでパワーオンでjailが正常に作動する
jail作動後のネットワークは以下になる。

問題

まだ問題が少し残っているが、通常運用には差し支えがないのでこれで良しとしている。
問題は、qjailを停止してもepairxbが復活しないことがある。その場合は停止後にepairを作成し直さないと開始ができない。
（少し待つと復活する場合もある）

LREC6860BTの使用について

ネットワークインターフェースをre0からtn400に変更するだけでできるはず

ネットワーク設定と確認

qjailの設定ファイルからネットワークの実インタフェース名がないので、rc.confの変更のみで行ける。

/etc/rc.conf
cloned_interfaces="epair0 epair1 bridge0"
ifconfig_epair0a="up mtu 9014"
ifconfig_epair1a="up mtu 9014"
ifconfig_tn400="up mtu 9014"
# ifconfig_re0="up mtu 9014"
ifconfig_bridge0="addm tn400 addm epair0a addm epair1a up mtu 9014"
# ifconfig_bridge0="addm re0 addm epair0a addm epair1a up mtu 9014"
ifconfig_bridge0_alias0="inet 192.168.1.31/24"

起動すると先ほどと同様の内容が確認できる。

ただ、sshで接続するときに時間がかかっている。この症状は、初回のみで2回目からは問題ない。

問題点

他のホスト（192.168.1.30）にピングを飛ばしても届かない

しかし、他のホスト（192.168.1.30）からのピングには応答し、その後は他のホスト（192.168.1.30）へのピングが通るようになる。

# ping 192.168.1.30

tcpdumpで確認すると自ホスト(bridge0)ではarpが送信されているが、他のホストではarpが届いていないことが分かった。加えて、bridgeを組まない場合はarpが他のホストまで届き、ifconfigの内容が以下のようになり、tn400のflagsにRUNNINGが示されているが、bridgeを組むとRUNNINGがない。

どうも、bridge0がtn400の機能を無効にできないとエラーを吐いているようです。

re0に比べ少し時間がかかったが正常に起動したようだ。

結論

LREC6860BTとbridgeを組み合わせるとLREC6860BTのflagsのRUNNINGが消えarpが出ていかないため、接続に問題が発生する。
bridge接続を組まず、LREC6860BT単体の場合はRUNNINGとなりarpも出るため正常に接続ができる。

intelのX540-T1

LREC6860BTを購入時に最悪windowsに使用するが当たってしまった。

全く問題なく作動した。

転送速度

以下３台で実施する。中間のX540-T2は2ch(ix0,ix1)をブリッジ接続している
Windows10(LREC6860BT) - FreeBSD12(X540-T2) - FreeBSD12(X540-T1)
約9GByteのファイルをWindows10とFreeBSD(X540-T1)でコピーして速度を観測した。

  • Windows10からFreeBSD12へ

  • FreeBSD12からWindows10へ

FreeBSD12のディスクは古いSSDであることからこのような差が出たと思うが、まずまずですね。
