oncedoc 硬件版本，安装官网最新2988版本后，无法使用原来的隧穿服务.
操作：
1. 将之前/onceai备份为了/onceaibak
2.按照教程安装了2988版本/onceai目录
3. 将/onceaibak中的 /onceaibak/oncedoc/mod/onceair目录copy回到/onceai/oncedoc/mod/onceair
4. 在/onceai/oncedoc目录下的USER_CONFIG文件中添加了onceair
5.在/onceai/oncedoc目录下的config中module——required部分添加了onceair
6.reboot
问题：
无法打开onceair隧穿功能。
（另外，查看onceair目录中的onceair.js，其中有验证license部分，是否该处与2988版本存在兼容问题。）

1. USER_CONFIG和 config.js 只面只需要改一处就可以了，因为模块加载了两次，所以出了重复翻译的ERROR，不过不影响使用。
Error: Variable already exists in app.model: local
2. build.2800 以后的模块注册加载的路径机制改过了，由绝对目录改成了相对当前目录。
\onceai\oncedoc\mod\onceair\svr\onceair.js
中最新的应该是
app.mod('onceair', '../web')
以前是绝对目录。改成这样可能可以解决。
下周我们把最新的onceair模块单独编出来发给你吧。
可以试试这个压缩包： http://onceoa.com/download/onceair.zip
谢谢，已经安装了最新版本的onceair，在“设置”的“服务"里也出现了内网穿透的选项 ”禁用外网访问 （内网穿透）“选的”否“，然后SSH远程登录和数据库远程登陆都打开了，网页端口8064.
1.现在问题是，在onceair.com网站绑定的网卡mac地址不变，但是无法连接上，上面显示最后在线时间10月25，
2.然后，同一局域网使用局域网查找，找不到onceair（2520版本的时候可以找到），同一件设备，隧穿的设置可能没有真正工作起来。
3. 另外提个建议，优化下控制面板中的选项，把第一个”系统“更改为”状态”或“性能“，第二个”系统“换成”应用或服务“最后的”服务“才应该改成”系统设置“。误解的可能性会更小。
感谢建议，会考虑更改。
你提到的问题，可能是服务器指向错误，可以尝试手动更改config.js： 将 MAIN_CONFIG.remoteSvr 改成 http://onceair.com
var MAIN_CONFIG = {
//domain name of this server
mainSvr : 'localhost:' + ONCEIO_CONFIG.port
//, remoteSvr : 'http://onceoa.com'
, remoteSvr : 'http://onceair.com'
, language : 'zh-CN'
, textEncoding : 'gbk'
问题已解决，谢谢。
