- FreeBSDにmgetty + sendfaxをいれてFAX試験環境を作る
仕事で使う８回線ＦＡＸサーバのデバッグのための評価環境としてPCを使った擬似多回線FAX
受信システムを作りました
パソコン1台に対し2台のFAXモデムを接続し、受信したFAXはイメージファイルに
変換して、ネットワーク経由でWIndowsクライアントからそのファイルを見られる
ようにしました。
ファイル形式はPBMです。これはPaintShopProとかで扱える形式です
JPEGかなんかにするフィルターを通してもいいんですが、これで見えるから
エエことにしました
パソコン側はOSにFreeBSD 3.4R、FAX受信ソフトはmgetty+sendfax
ファイルのネットワーク共有にsambaを使っています。
NTと違って遅いマシンでも動くし設定が楽でいいです。
仕事的には2時間くらいでセットアップ可能ですので人件費を考えても
・実機のFAX＝＠30000 2台で60000円
に比較して
・人件費 ＠5000円ｘ2時間 = 10000円
・FAXモデム ＠6000円 ｘ ２ = 12000円
・パソコン ＝ 廃物 ロハ
・FreeBSD、sendfaxなど ＝ ロハ
なんで経費削減効果はあきらか！
おまけに消耗品代はタダなので、何かの機器の評価で夜中連続で運転したい
ときなんか紙代もかからないしジャムったり紙がきれたりして評価中断なんて
悲しい目にもあわなくてすむのでうれしさ満点！
という理由で、どしどし職場にFreeBSDを導入しましょう！！
参考までに作業メモです
イメージファイルのパーミッションを666にしてますが、これは工場でジグ
として使うために敢えてイージーアクセスを優先した結果です

# This is the main Samba configuration file. You should read the

# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
