如何从 Mac 按需访问 SMB 网络共享？

我经常在运行 Leopard 的 Mac 上使用公司网络上的 samba 网络文件共享。当我通过 shell 或 Finder 访问代表性路径时，如何按需自动挂载这些共享？

理想情况下，我希望它像通过 /Volumes/smb/[host]/[share] 之类的路径从具有 UNC 路径（又名 \\[host][share]）的 Windows 访问网络共享一样简单。

我尝试使用 autofs‘可执行映射’支持，如以下链接所述：

下面是我稍微调整过的 auto.smb 脚本，但是它不起作用，我很困惑：

#!/bin/bash

# $Id: auto.smb,v 1.3 2005/04/05 13:02:09 raven Exp $

# This file must be executable to work! chmod 755!

# IC patch
# The problem with the original file was that it was executing smbclient -gL $key
# But $key contains the full path e.g.: server/share/subdir
# This was causing auto.smb to go to an endless loop
# This modified file corrects this problem by passing just the host to smbclient
# and in addition it provides a simple method to locate the credentials file
# The changed parts are marked as "IC patch"
# Please read the creddir variable description to see how to provide credentials files
# Note: When you search for an inexistent share, or you authentication fails the script behaves the wrong way
#       This is because smbclient does protest, it just falls back like calling it
#       as smbclient -gL host
#       A check at the smbclient output should be done to avoid this, but I haven't figured it out yet

# IC patch
# Look for credentials files under the creddir
# If $key is just the host name, then $credfile=$creddir/$host

您没有过多讲述您尝试了什么以及具体为何失败，因此很难提供帮助。

  • 您是否实际创建了 creddir“/etc/auto.smb.credentials”？

  • 您是否已使用包含您的凭据的 $host 文件填充了它？请向我们展示
    ls -Al /etc/auto.smb.credentials

  • 您的 auto.smb 脚本是否可执行，并从 /etc/auto_master 引用？让我们看看 cat /etc/auto_master 和ls -Al /etc/auto.smb

  • 您的 Mac 日志中有什么有趣的东西吗？我不确定 Mac 如何记录这些内容，但也许
    egrep 'auto(mount|fs)' /var/log/*会打印一些有用的信息？
