理光复印机关闭2049等端口
症状客户对网络进行安全扫描时，发现理光MFP机器开启了2049端口，但在机器的Web页中未找到相关的设置。维修过程在智能面板与MFP控制器进行通讯时使用了一些端口，同时对外部网络开放，造成进行安全扫描时出现警告。出于安全原因，可以关闭这些端口。
使用的端口包括：- 111/tcp- 1022/tcp- 1023/tcp- 2049/tcp- 18315/tcp- 54080/tcp- 54443/tcp- 65000/tcp1- 65001/tcp1- 111/udp1,2- 1022/udp- 1023/udp1这些端口预计在之后的固件中进行修复；2端口111/udp 今在以下机型中出现：D219/D220/D214/D196/D236, D259, M0B0/D0A0
要关闭这些端口，需要确认并升级固件；
