[debian-users:17334] [Q]afbackup didn't work on slink

いつみ と申します

ネットワーク指向のバックアップユーティリティ afbackup を使いたいのです
が、うまく動いてくれません。御指導を賜わりたく存じます

不具合の為再投稿しています、二重投稿となっているかもしれませんが
お許しください


現象

ストリーマーの付いているマシンに次に示すように slink のサーバークライアント

[Manbo:501]dpkg -l *afbackup*
Desired=Unknown/Install/Remove/Purge
| Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed
|/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad)
||/ Name            Version        Description
+++-===============-==============-============================================
ii  afbackup        3.1beta1-1     Client-Server Backup System (Server side)
ii  afbackup-client 3.1beta1-1     Client-Server Backup System (Client side)

両方をSlink環境にインストール、 /usr/doc/afbackup/{INTRO,CONFIG}に従っ
て設定をおこなった。なお使用するストリーマは、HP のＤＤＳ２で、device name
は /dev/nst0 である。tar 、taper 等では問題なく読み書きできている。


デビアンのインストーラによって 次のように /etc/services /etc/inetd.conf
には適切な記述が追加されたのを確認した。

/etc/services より抜粋
afbackup        2988/tcp                        # Afbackup system
afbackup        2988/udp                        # Afbackup system

/etc/inetd.conf より抜粋
afbackup stream tcp     nowait  root    /usr/sbin/afserver -b  server /etc/afbackup/serv
er.conf

念のため リブートしてから、ルートになって

#cartis 1;cartis -i 1 1

とカートリッジの数をシステムに教えてから、afclinet で(今教えたカートリッジの数を確認する
コマンドを打ってみたところ

# afclient -h localhost -q
Error: Cannot get the greeting message from server.

というエラー出力がされた。ps aux | grep afserver としてみると、サーバーが動いていないので
手でサーバーを立ち上げると

# afserver &			       ; -b オプションを付けても同じ結果だった

このときのサーバーのログを以下に示します。クライアントの方もログを取る設定にしてあるのですが
クライアントはログを吐きませんでした。


Sun Aug  1 18:23:24 1999, Warning: Could not get name of connected peer: Socket operatio
n on non-socket
sh: -c: line 1: syntax error near unexpected token `<unknown>'
sh: -c: line 1: `<unknown>'
Sun Aug  1 18:23:24 1999, Warning: Executing init command <unknown> returned exit status
 512.

これを見ると、ネットワークの設定がおかしいような感じですが、他のネットワーク機能今のところ
きちんと使えています。

この状態で、再び、ローカルホストでクライアントを動かしても、先程と同じエラーが出るだけです。
バックアップ等他機能のオプションをクライアント起動時に付けても全く同じエラーが出ます。

#  afclient -h localhost -X full_backup -k /etc/afbackup/cryptkey 
Error: Cannot get the greeting message from server.

何が悪いのか、見当も見当もつき。御指導をおねがいします

最後に /etc/afbackup/{server|client}.conf を付けます
