交互式全景图的免费软件？

4

是否有任何免费软件可以在 Ubuntu中创建交互式全景图（360º，比如这个）？

编辑： 我不仅需要一种创建静态全景图的方法（例如，JPG 文件），还需要一种将其转换为某种交互式格式（swf、mov ....）或某种实现方式的方法它在网页中，以便可以平移，旋转等（缩放也很好，但不是严格要求）。

使用 Evolution 备份 Gmail“已发送文件夹”

4

我想检索（最初通过 POP）我的 Gmail 帐户邮件，但这个想法只是为了保留这些邮件的备份。但 Gmail“已发送”邮件会被检索并与收到的邮件一起放入我的 Evolution 收件箱。如何从 Evolution 获取 Gmail“已发送”文件夹中的邮件？

（如果我也能获得我的 Gmail 标签，那就太好了，但这不是主要目标）

fail2ban 的日志 iptables “返回的 NNN” 条目是什么？（Fail2ban 未能禁止）

4

在我fail2ban.log的文章中有一些我不明白的条目（并且没有找到搜索）......我有几个“监狱”，我创建了一个特定的一个当他们尝试连接时禁止IP的Web 服务器搜索脚本，我猜....这些是来自给定 IP 的一些条目（对不起，长日志）：

为了防止这种情况，我在以下位置设置了一个自定义监狱/etc/fail2ban/jail.local：

[apache-404-slowattackers]
enabled = true
port = http,https
filter = apache-404-slowattackers
logpath = /var/log/apache*/*access.log
bantime = 344000
findtime = 172800
maxretry = 12

这是/etc/fail2ban/filter.d/apache-404-slowattackers.conf

[Definition]
failregex = (?P<host>[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}) .+ 404 [0-9]+ "
ignoreregex =

（与默认/etc/fail2ban/filter.d/apache-404.conf过滤器相同）

Fail2ban 确实会在某些 IP 对某些过滤器起作用时禁止某些 IP，但对我的自定义过滤器则没有。一些行来自/var/log/fail2ban.log：

如您所见，尝试禁止对我的自定义过滤器的攻击时失败（因此检测到此类攻击，但未正确禁止，我不知道为什么）

所以我的问题是：

这些错误是fail2ban问题还是问题iptables？
这些错误是什么意思？......以及......如何避免它们？
我做错了什么，或者我该如何纠正这种行为？

编辑：

也许这对回答这个问题（或不是）很有用，但iptables -L没有显示 my 的痕迹apache-404-slowattackers，而其他监狱存在：

这是否提供了进一步的线索？

如何将邮件（mailutils）配置为默认使用 Maildir 架构？

10

当我输入mail命令时，我得到一个“没有给 USER 的邮件”的答案，但确实有邮件（在/home/USER/Maildir/new）

我想这与邮箱采用 Maildir 格式而不是 mbox 有关，但我不知道如何告诉 mailutils（特别是 mail 命令）使用哪种格式。

为什么我的根文件系统总是在启动时被扫描？

5

我总是在启动时暂停说正在检查我的文件系统（也带有“按 C 取消”注释）。实际上（看到boot.log）我认为是/fs，它位于/dev/sdb5

这里有几个问题（希望这不会违反任何规则）：

这是正常的吗？
我可以（或者我什至应该）防止这种情况发生吗？
根据 boot.log（如下），fs 似乎并不“干净”，或者至少，它处于使 fsck 始终可以在一段时间内（仅几秒钟）出错的状态或条件。我该如何解决？

编辑：这是我的 boot.log：

输入特殊字符的方法？Alt+数字键可以吗？

18

我知道有这个问题如何输入像ë这样的特殊字符？，但我想知道是否有可能将键盘配置为使用窗口风格插入特殊字符（Alt+Code in numpad）。我知道这可以用Ctr++Shift代码来完成，U但是......

我必须启用 ibus，但不知道如何默认启用它
~~十六进制代码比十进制代码长~~ Ctrl+ Shift+ U+十六进制代码组合比Alt+十进制代码长
作为前 Windows(TM) 用户，我已经习惯了......

我经常使用的两个角色示例，比较 win 风格和 gnome 风格

Tilde (~) character
Windows -> Alt+1-2-6
gnome -> Ctrl+Shift+U+7-e

Superscript 2 - square (²) character
Windows -> Alt+2-5-3
gnome -> Ctrl+Shift+u+b-e

如果您尝试这些“组合键”，Windows 样式会更容易键入（不是主观的：同时使用的手指更少，按下的键也更少）。

由于我不想以某种主观的方式表达，我的问题是我可以将键盘配置为使用Alt+Numpad 样式，或者我是否需要坚持使用Ctrl+ Shift+U 组合（或组合键替代）

Inkscape 标尺中的奇怪故障

在使用 Inkscape 时，我遇到了一个奇怪的故障。标尺中显示当前光标位置的小箭头仍然存在，不会被删除。所以我以满是它们的尺子结束，或者只是用一条粗黑线结束。很明显，这会使这个功能变得毫无用处，因为我无法分辨光标的真实位置。这是一个例子：

同步 WM6 <-> Evolution.... opensync-module-python 丢失？

1

我正在尝试安装opensync-plugin-synce以将我的 wm6 手机与 Evolution 同步，但是当我尝试（从突触，也使用 ap-get）时，是：

Depende: opensync-module-python  but it is not installable

事实上，我还没有在存储库中找到 opensync-module-python。

有什么提示吗？有什么方法可以同步 WM6 和 Evolution（例如，最好没有像 Gmail 这样的中间在线同步）？

更新：opensync-module-python存在于以前版本的 Ubuntu 的存储库中（我的是 10.10）......我可以从那里安装它还是会毁掉一些东西？

更新：我应该将此标记为不可能吗？现在似乎无法将 WM6 手机与 Evolution 同步....
