Raspberry PIサーバ アクセス不能 (3)

前回の続き．

/etc/wpa_supplicant/wpa_supplicant.conf に暗号化したパスフレーズを記載してみたもののWRONG_KEYで再接続に失敗する症状は変わりませんでした．

ところで気づいたのですが，16:10頃にcarrier lostになることが多いようです．16時には別の高負荷のcron jobを流しています．ネットワークが高負荷になるときに問題が発生するのか．謎．

Raspberry PIサーバ アクセス不能 (2)

前回の続き．

調べているがよく分からない．

そこで，方向を変えて，↓こっちのメッセージを疑ってみることにする．つまり「WLANでときどきCarrier Lostするのはそういうもので，そのときに再接続できないのが問題」だと．

Nov 12 02:14:50 raspberrypi wpa_supplicant[516]: wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="XXXX" auth_failures=1 duration=10 reason=WRONG_KEY

/etc/wpa_supplicant/wpa_supplicant.confには正しいSSIDとpassphraseが平文で記載されていたので，wpa_passphraseコマンドでencryptしたパスフレーズを記載するようにしてみた．

ここが問題だとすると，boot時には接続できることが説明できない気がするけど，とりあえずこれで様子をみる．

Raspberry PIサーバ アクセス不能

終夜稼働させているRaspberry PIサーバが時々アクセスできなくなります．LEDは通常通り点滅しているので生きてはいそうなのですが，外部からsloginすることができず，pingにも反応しません．

仕方なく電源Off/Onで再起動して，/var/log/daemon.logを確認したところ，以下のようなlogが残っていました．前回同様の症状がでたときにも同様のlogが残っていたのでこれが関係しているのは間違いなさそうです．

Nov  8 16:12:13 raspberrypi wpa_supplicant[508]: wlan0: WPA: Failed to set GTK to the driver (alg=3 keylen=16 keyidx=1)
Nov  8 16:12:24 raspberrypi wpa_supplicant[508]: wlan0: CTRL-EVENT-DISCONNECTED bssid=00:3a:9d:68:c7:3f reason=1 locally_generated=1

Nov  8 16:12:59 raspberrypi systemd-udevd[16348]: '/sbin/crda' [16349] terminated by signal 9 (Killed)
Nov  8 16:13:05 raspberrypi dhcpcd[681]: wlan0: carrier lost
Nov  8 16:13:39 raspberrypi systemd-udevd[16348]: timeout '/sbin/crda'
Nov  8 16:13:39 raspberrypi systemd-udevd[16348]: timeout: killing '/sbin/crda' [16351]
Nov  8 16:13:39 raspberrypi systemd-udevd[16348]: '/sbin/crda' [16351] terminated by signal 9 (Killed)

なんだろう？

ImageWriter

Raspberry PIのSDカードのバックアップにImageWriterを使っているが，ReadとWriterの向きがいつも分からなくなるのでメモ．

• Read : SDカードからImageファイル
• Write : ImageファイルからSDカード
