重置系统用默认账号telecomadmin nE7jA%5m 登录，开启telnet http://192.168.1.1:8080/enableTelnet.html
使用设置的telnet账号密码登录，输入;提权到root：

;
sh: syntax error: unexpected ";"
echo $USER
root
qoecmd telnetadmin #获取su密码
qoecmd Register set status 0 result 1 #修改ITMS状态为注册成功

关闭插件启动：

rm -rf /opt/upt/apps/apps && touch /opt/upt/apps/apps && reboot
#恢复
rm -rf /opt/upt/apps/apps && mkdir /opt/upt/apps/apps && reboot

修改这个文件可以开机启动，要恢复插件启动：

/opt/upt/apps/apps/opt/apps/opmaintain/diagapps/ommonitord

获取管理员密码，如果可以重置系统可使用默认账号CMCCAdmin aDm8H%MdA 登录，使用普通用户登录web，然后打开http://192.168.1.1/cgi-bin/telnetenable.cgi?telnetenable=1&key=xxxxx ，xxxxx替换为去分隔符的大写mac地址，然后登录telnet：

admin
Fh@xxxxxx  #密码 Fh@加上mac后6位

然后获取超管:

cfg_cmd get InternetGatewayDevice.DeviceInfo.X_CMCC_TeleComAccount.Username
cfg_cmd get InternetGatewayDevice.DeviceInfo.X_CMCC_TeleComAccount.Password

开启root用户登录，以管理账户登录后打开http://192.168.1.1/cgi-bin/FactoryInfoCheck.cgi 抽检模式，root账号默认密码hg2x0

一些设置：

cfg_cmd set InternetGatewayDevice.X_CMCC_UserInfo.RegMode 1 #loid认证
cfg_cmd set InternetGatewayDevice.ManagementServer.PeriodicInformEnable 0 #关闭RMS的上报
cfg_cmd set InternetGatewayDevice.ManagementServer.URL http://127.0.0.1/ #修改RMS认证地址
#查看所有参数
cfg_cmd showvalue InternetGatewayDevice. 1
#更改地区
load_cli factory
set factorymode enable
load preconfig Temp #可手工删除tr069，关闭RMS
set factorymode disable

以工厂模式启动，开机会启动telnet(root可登录)，禁用java等插件：

touch /var/factoryenable
/fhrom/bin/get_led_config
rm -rf /var/factoryenable
mount -o remount,sync,rw /fhdata
touch /fhdata/factorymodeflag
sync
mount -o remount,ro /fhdata
/fhrom/bin/get_led_config

1.先重置系统，开机后按住reset键20秒
2.使用web管理员 CMCCAdmin aDm8H%MdA 登录系统，开启文件共享ftp
3.开启telnet: http://192.168.1.1/system.cgi?telnet
4.使用光猫背后的普通用户登录telent，然后执行：

#提升管理员权限,密码为刚才登录输入的密码
su user_ftp
#修改web超管账号和密码
cfgcli -s InternetGatewayDevice.DeviceInfo.X_CT-COM_TeleComAccount.UserName admin
cfgcli -s InternetGatewayDevice.DeviceInfo.X_CT-COM_TeleComAccount.Password password
#root用户密码,后续可用root账号登录telnet
cfgcli -s InternetGatewayDevice.DeviceInfo.X_CT-COM_ServiceManage.SuPassword rootpass
#修改ITMS状态为注册成功
cfgcli -s InternetGatewayDevice.X_CT-COM_UserInfo.Status 0
cfgcli -s InternetGatewayDevice.X_CT-COM_UserInfo.Result 1

修改光猫型号为G-140W-UG：

ritool dump
ritool set Mnemonic G-140W-UG

登录web使用loid注册，手工配置网络信息，正常使用。
TR069默认不能点击删除，F12删除disable字段就可以了。

smokeping slave同步时master出现大量错误：

RRDs::update ERROR: /data/smokeping/data/Ping/alidns-v4~test.rrd: illegal attempt to update using time 1741511679 when last update time is 1741524039 (minimum one second step)

清空/data/smokeping/data/后只运行master没问题，再次启动slave就重复出现大量上面错误。
原因是fcgiwrap的运行用户和smokeping的运行用户不一样，导致读写/data/smokeping/data/__cgi/Ping/目录下文件有权限问题。
修改fcgiwrap.service运行用户和smokeping.service一样为smokeping:

User=smokeping
Group=smokeping

并调整下面文件的权限：

chown smokeping:smokeping /etc/smokeping/smokeping_secrets
chown -R smokeping:smokeping /data/smokeping/data/__cgi/
chown -R smokeping:smokeping /usr/local/smokeping/htdocs/images/

在编译smartdns时开启debug模式：

make DEBUG=1

通过valgrind启动smartdns：

valgrind --log-file=valgrind.log --tool=memcheck --leak-check=full --show-leak-kinds=all ./src/smartdns -f -c ./smartdns.conf
