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/udp
1  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;
